Description
Technical field
The invention belongs to the auxiliary control field of automobile intelligent, relate to a kind of major trunk roads speed of a motor vehicle planing method based on single intersection traffic signals information, also significant for mixed power electric car, Control of Electric Vehicles.
Background technology
Oil crisis is one of major issue of China's economic development faces always.The fuel consume that reduces automobile can effectively reduce the consumption of petroleum in Urban Transportation field, and China's energy sustainable development is had great importance.The fuel consume of orthodox car and driver's acceleration and brake operation course, and dead time is closely related.When automobile moves on through street, can freely travel, the engine rotation that as far as possible remains a constant speed, fuel economy is relatively better.But, when automobile moves on major urban arterial highway, can be subject to the impact of traffic lights, constantly accelerate, the operation of braking, idling, not only the fuel consume of engine increases, and has potential safety hazard.In fact,, in order to reduce the fuel consume of automobile in the time that major trunk roads travel, running car need to be accomplished following 3 points as far as possible:
1), while avoiding by traffic intersection, accelerate fast and brake operating;
2) while avoiding red light, arrive traffic intersection, idle for a long time;
3) speed of a motor vehicle control while automobile being passed through to traffic intersection within limits.
Because driver's vision and drive reaction distance are about 75 meters, that is, the traffic intersection that automobile has traffic lights in distance is about to make in 75 meters and accelerates or brake operating just can affect automobile by the mode of traffic intersection.But because driver cannot accurately predict the situation of change of traffic lights, therefore when by traffic intersection, may take to accelerate fast or braking, and be difficult to initiatively avoid the front auto idle speed of red light.
Perfect along with the development of Modern wireless communication technology and ground communication equipment, when automobile travels on major trunk roads, reach thousands of rice even if automobile and front have the traffic intersection distance of traffic lights, still can obtain in real time this traffic intersection signal information accurately.Speed of a motor vehicle planing method plans the speed of a motor vehicle according to signal information exactly, and offers driver as steered reference, thereby controls the method for the speed of a motor vehicle of automobile as far as possible.The method not only can be avoided driver's quick acceleration and brake operating, and can maximum possible make automobile in the time of green light by traffic intersection, reduce the fuel consume of automobile.But domestic at present, the technology and the method that also do not have relevant automobile speed to plan.
When the present invention is directed to automobile and moving, set up a kind of major trunk roads speed of a motor vehicle planing method based on single intersection traffic signals information on relatively unobstructed major trunk roads.The nearest traffic lights information in front that the method obtains by wireless telecommunications system, automobilism time and acceleration are optimized, and by the speed of a motor vehicle curve of cooking up is offered to driver as steered reference, thereby make automobile can avoid the quick acceleration and deceleration operation bringing due to signal lamp, and idle, fuel consume when reduction automobile moves on relatively unobstructed major trunk roads.
Summary of the invention
Because current China is not to automobile primary arterial highway speed of a motor vehicle planing method and technology, affect to a certain extent automobile fuel ecomomy, in order to make up this deficiency, consider the impact of traffic behavior, the present invention, according to the signal information of the nearest traffic intersection in front, plans calculating to automobile speed, and running time and acceleration are optimized, then by the speed of a motor vehicle of having planned is offered to driver as steered reference, thereby reduce the fuel consume of automobile.
The present invention is achieved through the following technical solutions.A major trunk roads speed of a motor vehicle planing method based on single intersection traffic signals information, comprises the following steps:
Step 1): obtain nearest traffic lights data.Automobile enters section, first obtains nearest traffic intersection signal lamp delta data t by wireless communication system
s, s ∈ { g, r}.S is signal lamp type, and g represents green light, and r represents red light.There are two kinds of situations in signal lamp change situation, as shown in Figure 1.In the time running into signal lamp and be initially red light, define the time that is transformed to green light for the 1st time and be
the time that is transformed to red light for the 2nd time is
then the time that is transformed to green light for the 3rd time is
by that analogy.In like manner, in the time being initially green light,
by that analogy.
Step 2): obtain the distance with nearest traffic lights.Automobile enters i section, obtains the distance B of the signal lamp in automobile and i section by wireless location system
i.
Step 3): determine by traffic intersection time range.Consider the flow of road, need to reduce automobile by the time in section as far as possible.The mode of operation that the automobile shortest time arrives road cross is: first from initial velocity v
0, with the maximal value a of acceleration
haccelerate, reach the speed of a motor vehicle maximal value v that road allows
limafter, traffic intersection travels at the uniform speed.
Therefore, the acceleration time t of automobile
afor:
With speed of a motor vehicle v
limthe time of traveling at the uniform speed be:
The automobile shortest time is t by the time at crossing
t,

Automobile passes through traffic intersection
itime interval on be limited to t
l, under be limited to t
h, automobile by the time section at i crossing is
Be green light for automobile is arrived when traffic intersection, when automobile is with the shortest time during by i crossing, when the initialize signal of the traffic signals information of receiving is green light, automobile by the time interval of traffic intersection is:
If
?
If
?
In formula, k is that signal changes number of times.
Step 4): the calculation optimization speed of a motor vehicle.In order to improve the fuel consume performance of automobile, speed of a motor vehicle planning algorithm need to keep the speed of a motor vehicle constant as far as possible, reduces unnecessary acceleration or brake operating.The present invention, in the time of the planning of the enterprising driving speed of relatively unobstructed major trunk roads, adopts automobile only once to accelerate or the method for brake operating.Automobile is first with initial velocity v
0travel at the uniform speed; Then at moment t
s, the time of carrying out is t
eacceleration or brake operating by traffic intersection, acceleration is a.
In order to ensure the handling capacity of road, need to make automobile exist
in time, pass through traffic intersection.In addition, in order to improve the fuel economy of automobile, need to make the speed of a motor vehicle of automobile change minimum.Therefore, the present invention using by time and acceleration absolute value sum as optimization aim, majorized function as shown in the formula:

Step 5): judge above-mentioned steps 4) equation whether have solution.If there is solution, forward step 6 to); If without solution, forward step 7 to).
Step 6): at the uniform velocity travel with initial velocity, then with acceleration or retarded velocity operation;
Step 7): with acceleration or retarded velocity operation, more at the uniform velocity travel;
Step 8): determining step 6) whether exist with too low initial velocity and travel for a long time, if so, forward step 9 to);
Step 9): recalculate the optimization speed of a motor vehicle, calculate Accelerating running time, the time of traveling at the uniform speed and stop working time.If automobile speed of at the uniform velocity travelling when starting is too low, can cause fuel consume still very high.Therefore the present invention is carrying out after speed of a motor vehicle planning, if automobile is with initial velocity v
0while traveling at the uniform speed, v
0too small, v
0< v
