The device comprises a rear view mirror (1), an alarm identifier (2) and an adjusting frame (3), wherein the adjusting frame (3) is fixedly arranged on the rear view mirror (1); the alarm identifier (2) is transversely arranged on the adjusting frame (3); the position of the alarm identifier (2) on the rear view mirror (1) corresponds to the tail end of a vehicle; the alarm identifier (2) can slide on the adjusting frame (3) according to the requirement, and corresponds to the tail end of the vehicle or the rear of the tail end of the vehicle; and the driver determines the vehicle distance between a rear vehicle and the vehicle and the vehicle speed according to the alarm identifier (2) and cannot easily perform operation of overtaking, changing a lane or driving back to the original lane, so that the determination accuracy of the driver is greatly improved, and the aim of safe driving is fulfilled.
Description
Technical field
The present invention relates to the condition discriminating apparatus of a kind of spacing and the speed of a motor vehicle.
Background technology
At present, automobile driver is all known and is being overtaken other vehicles, lane change, before sailing go back to former track, the distribution situation of vehicle around all needing to observe, guaranteeing under the safe situation, just can overtake other vehicles, lane change, sail back corresponding operatings such as former track, in this process, whether driver's observation the place ahead and both sides have car all is than being easier to easily, but, distinguish the speed of rear car and the distance between front vehicle and the vehicle of oneself by back mirror, difficulty just relatively, especially when between back vehicle and this car apart from more approaching the time, but also to consider the speed of back vehicle and the speed of this car driving, see whether whether the rear speed of a motor vehicle faster than the speed of this car, night travel particularly, all vehicles are all opened headlight, under the shining of light, be difficult to more to judge front vehicle the position and with the distance of this car, and the speed of two vehicles, frequent like this owing to judging the inaccurate traffic accident that causes, caused very big harm to society.
This programme applicant's inspiration comes from the inverted image of car, when the sun when oblique upside shines vehicle body, can shadow appear on one side of vehicle, the length of shadow is very near the length of vehicle, the end points of vehicle afterbody is the starting point of shadow, chaufeur is sitting in and sees back mirror on the seat, can see shadow from back mirror, chaufeur can be observed the situation of front vehicle according to shadow in the position of back mirror, the distance of judgement front vehicle and this car reaches the speed with this car speed of a motor vehicle, can not go easily to carry out and overtake other vehicles, lane change or sail back the operation in former track improves the accuracy that chaufeur is judged greatly, reaches the purpose of safe driving, but such mode is subjected to the influence of weather, must be when daytime the sun being arranged, and the position of shadow also must be satisfied concordant with the vehicle tail end, otherwise, same judgement is inaccurate, make that the degree of utilization of chaufeur is lower, can not exist certain inconvenience equally for a long time for chaufeur provides foundation.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of driver safety of reminding to drive, prevent vehicle rear-end collision collision, the spacing that reduces the traffic accident incidence and the condition discriminating apparatus of the speed of a motor vehicle.
The technical scheme that condition discriminating apparatus adopted of the first kind of spacing of the present invention and the speed of a motor vehicle is: described condition discriminating apparatus comprises back mirror and the warning sign that is arranged on the described back mirror, and the position that described warning is identified on the described back mirror is corresponding consistent with the vehicle tail end.
Optimize, the position that described warning is identified on the described back mirror is corresponding consistent with the 3-7 rice at the rear of vehicle tail end.
Optimize, described warning sign is arranged on can slide up and down with described back mirror on the described back mirror and cooperates.
Optimize, described condition discriminating apparatus also comprises the adjusting framework, and described conditioning box frame is arranged on the described back mirror, and described warning sign is arranged on the described adjusting framework and described adjusting framework bearing fit.
Optimize, described conditioning box sets up and is equipped with scale mark, and described scale mark is corresponding with the back of vehicle afterbody.
The technical scheme that condition discriminating apparatus adopted of the second kind of spacing of the present invention and the speed of a motor vehicle is: described condition discriminating apparatus comprises camera, the read-out that is electrically connected with described camera, is arranged on the warning sign on the described read-out, and the position that described warning is identified on the described read-out is corresponding consistent with the vehicle tail end.
Optimize, the position that described warning is identified on the described read-out is corresponding consistent with the 3-7 rice at the rear of vehicle tail end.
Optimize, described warning sign is arranged on can slide up and down with described read-out on the described read-out and cooperates.
Optimize, described condition discriminating apparatus also comprises the adjusting framework, and described conditioning box frame is arranged on the described read-out, and described warning sign is arranged on the described adjusting framework and described adjusting framework bearing fit.
Optimize, described conditioning box sets up and is equipped with scale mark, and described scale mark is corresponding with the back of vehicle afterbody.
The beneficial effect of the condition discriminating apparatus of the first kind of spacing of the present invention and the speed of a motor vehicle is: because described condition discriminating apparatus comprises back mirror and the warning sign that is arranged on the described back mirror, the position that described warning is identified on the described back mirror is corresponding consistent with the vehicle tail end, chaufeur judges that according to described warning sign the distance of front vehicle and this car reaches and the speed of this car speed of a motor vehicle, can not go easily to carry out and overtake other vehicles, lane change or the operation of sailing Hui Yuandao, improve the accuracy that chaufeur is judged greatly, the present invention reaches the purpose of safe driving, so can remind driver safety to drive, prevent the vehicle rear-end collision collision, reduce the traffic accident incidence.
The beneficial effect of the condition discriminating apparatus of the second kind of spacing of the present invention and the speed of a motor vehicle is: because condition discriminating apparatus of the present invention comprises camera, the read-out that is electrically connected with described camera, be arranged on the warning sign on the described read-out, the position that described warning is identified on the described read-out is corresponding consistent with the vehicle tail end, the image that obtains by described camera is presented on the read-out, judge that according to described warning sign the distance of front vehicle and this car reaches and the speed of this car speed of a motor vehicle in conjunction with described warning sign chaufeur, can not go easily to carry out and overtake other vehicles, lane change or sail back the operation in former track, improve the accuracy that chaufeur is judged greatly, the present invention reaches the purpose of safe driving, so can remind driver safety to drive, prevent the vehicle rear-end collision collision, reduce the traffic accident incidence.
