Have recognized that, the braking custom of vehicle driver can the energy expenditure of appreciable impact motor vehicles, It addition, the identification of high energy efficiency route is had a significant impact by it.The braking custom of vehicle driver is also than adding Speed strategy is more important.

In scope of the present application, " energy " refers to the energy source of vehicle, its include but not limited to gasoline, Battery and electric energy.Additionally, vehicle can include internal-combustion engine vehicle (such as, the vehicle with gasoline as power), mix Close power car, electric vehicle etc..

Fig. 1 shows that (it is probably and determines high energy efficiency route the driving style for determining vehicle driver A factor) system module and the block diagram of process.The part determined as this, can be according to route The route that each section aligns travelling (or will travel) carries out classify (frame 100).Can be by from vehicle modules And/or the data that sensor (as described below) obtains are to determine this classification.In one embodiment, can be based on Navigation (such as, map) data determine the route from starting point to destination.

For these routes and/or for a plurality of possible route, can be that this route determines/predict that energy disappears Consumption state.In this respect, it is contemplated that one or more possible variations.Each bar route may be logically divided into Individually element or section, the information of these single elements or section is respectively included in map datum.Logical Cross consideration variation, the energy expenditure of vehicle can be determined when vehicle drives through each section.Can be to dividing Each in the single element of dispensing route or the energy consumption values of section sues for peace, to provide to route Energy expenditure.

Based on the energy expenditure being assigned at least one route, it may be determined that for the angle of energy expenditure Whether this route is optimum.In one embodiment, can be that a plurality of possible route determines respective The energy expenditure of prediction, based on the energy consumption values to every route can relatively determine that energy expenditure is Excellent route.High energy efficiency route can be determined by possible route overall energy consumption minimum (determined by such as, from starting point to destination) route.

Additionally or altematively, high energy efficiency route can be based on various standards or constraint (as described below) Route optimum for the angle of energy expenditure.As a non-limiting example, it is contemplated that during traveling Between (such as, required maximum time).Alternatively or additionally, it is contemplated that traffic rules so that (such as) Constraint in terms of traffic can be excluded outside this determines.Such as, the section of paying can be got rid of.? This respect, such condition can be listed in fixing exclusion standard, and/or can be included in and energy expenditure In conjunction with weighted array in.In order to briefly, expense is provided as example, but, in addition to expense or Person can be used for during this determines as other constraints one or more of the replacement of expense.

With reference to Fig. 1, can determine driver's by recording the driving data as the function of relevant parameter Driving style.Can be (not shown, such as, from being stored in from the navigation system of the GPS auxiliary as example Map datum in storage media) obtain current location and current direction that motor vehicles travel.Map datum can Represent position and the part of travel direction thereof that the motor vehicles of traffic routing network are currently located.

For each part of route, map datum can include the various piece for defining route or satisfy the need The various piece of line carries out the parameter classified.The non-limiting example of such parameter may include but be not limited to, Category of roads 102 (such as but not limited to, the suitability of traffic, the width of road, covering etc.), speed Limit 104 (based on each route portion, each travel direction and/or other traffic rules) and the gradients 106. It addition, described parameter can include relevant with crossroad, cross point, priority pass rule, traffic lights etc. Information (frame 108).

As illustrated by block 110, may also include other parameters.In certain embodiments, described parameter can be additionally Including terrain information (such as, height above sea level and bending radius).As non-limiting example, described parameter can Including in the region within whether being located at somewhere about various piece or section or outside somewhere Information.If route portion comprises more than one bend, the most described parameter may also include with bend quantity with And average bending radius or the relevant information of minimum bending radius.

Based on route parameter, can obtain or determine that (it can be one for the classification of the road currently travelled Dimension or multidimensional).Therefore, this classification could be for determining the driving style (frame 116) of vehicle driver At least one input.

Determine that other inputs of driving style can include what other modules from vehicle and/or sensor obtained The operational factor (frame 112) of motor vehicles.The such parameter that can be registered as driving parameters can include but not It is limited to speed, acceleration, braking deceleration, gear shift, gear selection, dead time, passenger and/or goods The quantity etc. of thing.

Input additionally can include destination's (frame 114) of time, date and motor vehicles.Also can collect The parameter relevant with traffic or ambient parameter, and these parameters can be used as determining the driving wind of driver The basis of lattice.

Determined by one or more non-limiting examples of the data being continuously recorded described above and drive The driving style of the person of sailing.Driving style may be structured to (such as) function, performance plot, or may be structured to One or more dimensions is classified.Driving style may indicate that (such as) driver behavior goes out as in various parameters Or which kind of behavior of the function of multiple parameter.As non-limiting example, driving style may indicate that driver Attempt to reach or manage to keep which kind of speed (assuming that the combination of specific parameter) and driver for accelerating or Slow down and take which measure.Therefore, (such as) crossroad, stop sign or rotary island may define spy Determine the braking action of driver or accelerate behavior.In the case of braking and accelerating, specific driver can Show specific gear shift behavior and gear housing choice behavior.When at the uniform velocity driving, specific driver may be partially Like specific transmission ratio, this gear ratio within somewhere from be probably outside somewhere different 's.Driver also can show the different behaviors of the function as time of day or destination.

Therefore, in addition to some variations, driving style (and relevant speed strategy, acceleration strategy and Braking strategy) it is also based on classification of road.So, the practical prediction to driving behavior can be conducive to, And can determine that the estimation to the consumption in route segment and/or route.

Can driving style based on specific driver be the energy expenditure that route determines prediction.When travelling During to fixed line, the driving style of driver can affect energy expenditure.In different situations, driver Driving style energy expenditure may be produced different impact.Such as, same driver is in urban traffic Descend and on backroad or highway, be likely to be of different driving styles.To this end, disappear from energy May be low-energy-efficiency for another driver to the route that driver is favourable for the angle of consumption 's.Therefore, for route, the driving style utilizing specific driver determines that the energy expenditure of prediction can be more It is accurately determined the route that energy expenditure is optimum.

As example, Fig. 2 provides the comparison of two kinds of different driving styles, so that driving style pair to be described The impact of energy expenditure.Fine rule 201 shows that the behavior of driver A, thick line 202 represent driver B Behavior, both behaviors are all for the traffic in somewhere or urban transportation.Dotted line respectively illustrates On the road under traffic outside somewhere or the on a highway behavior (line 203) of driver A Behavior (line 204) with driver B.As in figure 2 it is shown, under the traffic that driver A is outside somewhere Than accelerating faster under the traffic within somewhere, and the behavior contrast of driver B.Driver The braking deceleration of braking and braking under the traffic outside somewhere under A traffic within somewhere Braking deceleration is almost identical, and the brake percentage selected under the traffic that driver B is outside somewhere is at certain The braking selected under traffic within area is higher.

Different acceleration strategies and braking strategy not only can be according within being positioned at somewhere or be positioned at somewhere External make a distinction, and can be according to directly affecting energy expenditure and/or by the impact on driving style And other conditions multiple affecting energy expenditure make a distinction.To describe in further detail for Fig. 3 This is on the one hand.

Can be path prediction energy expenditure based on braking strategy.Single element or the section of route can determined Energy expenditure time consider braking strategy.Therefore, estimated accuracy and the high energy efficiency of energy expenditure can be improved The determination precision of route.

In one embodiment, during braking strategy may include determining whether to activate the braking of one or more types Which kind of.Such as, type of retardation can include the service brake of motor vehicles, engine braking and/or electronic Braking.As an example, when (such as) reduces speed, it may be determined that type of retardation to be used.One In the case of Xie, use system rather than the use reclaiming (such as, regeneration) energy from the kinetic energy of motor vehicles The service brake (being generally activated by brake pedal) of motor vehicles, energy efficiency may be higher.This In the case of, described system can be used with to vehicle electrical by increasing the output voltage from (such as) electromotor Charging in pond, or can use described system by using specific electrodynamic braking.In other cases, Vehicle potential energy converting and energy in negative slope can be become motor vehicles can energy be probably useful.

In another case, the use (such as, " engine braking ") of the braking effect of electromotor can affect Energy expenditure.In this case, explosive motor continues to run with during engine braking, and does not disappears Consumption fuel (contrary with such as idling mode).Can also adjust electromotor temperature critically important for efficiency of combustion Degree.In another case, vehicle slides during slowing down or before stopping completely and is likely more favorably, Rather than keep existing speed.

Type of retardation (such as, slowing down) more efficient for energy expenditure can be depending on and (such as but do not limits In) braking occur time initial velocity, braking occur after target velocity, the consumption of deboost phase and with Realize the distance travelled between point slowed down.

Braking strategy can be the function of one or more characteristics of route.These characteristics can include road The positive gradient and/or negative slope, speed and/or with can cause velocity variations travelling characteristic (such as but not limited to Bend, speed limit or traffic lights) between distance.Additionally, these conditions can be dependent on the shape of surrounding Condition (such as, environmental factors) and/or traffic.Such as, vehicle is under intensive traffic or when seeing The energy force rate slided when spending low is more difficult under sparse traffic.

In certain embodiments, service brake can have such condition, and electromotor may under this condition Can shut down.Such condition can include (such as) minimum down time (standing time), if super Spend this time, then cause vehicle motor to shut down.Other conditions can be there are, for brief purpose, Do not clearly state other conditions described.

When for path prediction energy expenditure, can additionally perform to identify type of retardation to be used.Such as, Forecast consumption can be carried out based on the terrain information (such as, bend, negative slope and speed limit) relevant with this route, Additionally, the various braking methods determined by terrain information can be used to carry out forecast consumption.Can be by assuming that corresponding Probability and the additional information that used can be the brake condition relevant with traffic.Accordingly, it can be determined that it is pre- The consumption surveyed and the route consuming optimum.

Fig. 3 is the example of the data stream representing the various variations worked in the calculating of energy expenditure Property diagram.As it is shown on figure 3, for the sake of clarity, each variation be divided into vehicle parameter group 300, Road parameters group 302, specific driver parameter and/or driving style group 304, ambient parameter group 306 with And traffic parameter group 308.Fig. 3 is nonrestrictive, thus can rearrange and revise these packet and/ Or the element of these packets.Additionally, one or more parameters (or parameter set) can be added to the ginseng of Fig. 3 Manifold or delete from the parameter set of Fig. 3.

As shown in dotted arrow 301, may between each variation and/or between the group of variation There is relation.Such as, weather conditions not only can directly affect fuel consumption in route segment (such as, due to Wind on the horizon or extra high temperature or the lowest temperature), and can remote-effects and driver The relevant fuel consumption of driving style.As non-limiting example, it is vaporous that driving style can be dependent on sky Condition (such as, visibility).Though not shown, other parameters one or more (such as, road condition, Travel the relevant parameter of relevant parameter, route and vehicle parameter) also can directly affect energy expenditure and/ Or by the driving style remote-effects energy expenditure of driver.

The specific driving style of driver can include the braking action (group 304) of personalization.Such as, driver Service brake, engine braking, regenerative braking or when vehicle motor remains static can be used Close electromotor.Accordingly it is contemplated that this braking action so that this braking action can be according to driver Or driving style and in different situations and occur with different frequency.Therefore, can drive based on specific The braking action of the person of sailing predicts energy expenditure.

In one embodiment, the driving style of specific driver can based on (such as) as when vehicle at the uniform velocity Function during traveling and as speed, deceleration during the acceleration and/or braking of period of giving it the gun The selection of the transmission ratio of the function of degree.Transmission ratio also can affect engine braking or energy Amount reclaims.It addition, driving style can joint based on clutch and separation, as the function of gearshift procedure, Clutch also can affect consumption.The driving style of driver be also based on resting state operational mode information or The idle pattern information of person.As example, can stop under relatively long resting state about electromotor Operating provides described information.Such information can be that different types of vehicle (especially has hand gear The vehicle of case) more accurately determine the route that energy expenditure is optimum.

The driving style of specific driver can be the function of driving environment.Therefore, the driving wind of driver Lattice can be influenced by factors, and the different piece of route or section can be played different effects by described factor.? In this case, can obtain energy expenditure in various piece or section and on whole piece route is more smart True estimation.

In one embodiment, the driving style of specific driver can be dependent on route, such as, for one Each section of bar or a plurality of route, driving style is probably different.In this manner it is achieved that in view of (example As) driving style of driver on a highway can with on the backroad with multiple bend, The driving style of the driver on narrow secondary road or under urban traffic is different, can be to drive Member predicts energy expenditure and/or determines high energy efficiency route.

In certain embodiments, the information can being correlated with by route is to determine that driver is to go back on the road being on duty It is to travel on next road or in its spare time.Every kind of situation all can have different time pressures, As a result, the driving style of driver can be affected.Therefore, when the driving style of specific driver can be depending on Between.Such as, time of day or in one week within one day, to can determine that whether driver is carried out relevant with work Travel or whether travel in its spare time.Due to the driving style of driver under intensive traffic with May be entirely different, so driving style may also depend upon anticipated motor vehicles and passes through under sparse traffic Some routes or the time of Some routes section.Can determine based on the time or by current traffic Such information.

In additionally or alternatively embodiment, weather conditions and the condition of road surface relevant with weather also can shadows Ring the driving style of specific driver.Such as, owing to mist or precipitation, when low visibility, drive Member can show and the diverse driving style when visibility good.Similarly, the seeing of driver Degree can be avenged or rain shadow rings.Driver can make its driving style adapt to these the most in a different manner Situation.Therefore, the driving of the specific driver of function based on the respective situation as particular way line segment Style, can realize the determination of energy expenditure and/or route.

It addition, the driving style of driver may also depend upon current vehicle parameter.Such as, the goods of vehicle Motor vehicles consumption in given section is not only worked but also is acted as the driving style of driver by thing With.Such as, compared with when the vehicle is unladen, when goods increases, driver can use the maximum of permission Speed.Additionally, driving style may also depend upon whether driver travels alone or front row seat in vehicle Chair passenger is the most also in travelling.Driving style can additionally or altematively depend on having how many other passengers or There are which other passenger in person.This can equally be well applied to trailer operational mode, and this pattern not only affects permission Maximal rate and also affect the driving style of driver.Gear selects also to can be depending on vehicle parameter.By Can change to the goods of (such as) vehicle react in a different manner in driver, so will drive Style accounts for providing more accurate adjustment for the consumption of prediction on route as the function of Current vehicle parameter Estimate.Correspondingly, also can realize the determination consuming optimum route more accurate adjustment.

It is for determining the data stream of high energy efficiency route and the exemplary diagram of system referring now to Fig. 4, Fig. 4 Show, at motor vehicles run duration, data (402) can be recorded at vehicle, to determine the driving of driver Style.The data of record can be in driving parameters, ambient parameter, traffic parameter and vehicle parameter One or more offer bases, these parameters are for following the tracks of/monitor the driving behavior of driver.

As an example, the current location of the recordable motor vehicles determined by GPS system 404 and The driving parameters of the traveling section determined by map datum 406 or characteristic.The most recordable or record alternatively Current time and/or ambient parameter, traffic parameter and vehicle parameter.Additionally, recordable driving style 414, Such as, the acceleration of driver and the activation of braking action, travel speed and shift bar, implement at some In example, the additional function relevant with consumption (such as, air conditioning system or window) of the most recordable motor vehicles. In order to determine the driving style (as the function of environmental aspect) of driver, such data can be collected, with base The behavior of driver is determined in the characteristic and situation travelling section.Can be in the case of difference as far as possible and pin Different driving parameters as much as possible are determined the driving style of driver.This individual's driving style can The energy expenditure of the prediction being stored and used for estimating in route segment or route.

Consume optimum route to determine, can be from starting point to mesh by the map datum 406 of storage Multiple sections of potential route on ground determine relevant driving parameters.In this respect, can be based on map datum 406, the current location determined by gps receiver 404 and the purpose (such as) inputted by driver Ground determines route and route segment.It will be appreciated that in the diagram only by example mode specifically Understand some relevant parameters.

In the travel route section determined by driving style, the service data of the motor vehicles of available record 402 (such as, gear selects and speed) identify driver.In certain embodiments, the road of hundreds of meter Line segment may be enough to identify driver and/or driving style.Certainly, it is not intended to units of measurement, can be according to this Invention be embodied as use other units of measurement.Additional calculations can be based on the driving with driver of storage The data that style is relevant.

In certain embodiments, by recording and service data can be evaluated together with one or more parameters (such as But it is not limited to, driving parameters) additionally or altematively determine and/or the driving style of more fresh driver.As Fruit determines the driving style that deviate from storage, then can trigger new route based on the traffic changed optimum Change.As example, change based on traffic density variation route can be determined.
