Traveling vehicle collision preventing method

Abstract

The invention relates to a traveling vehicle collision preventing method. If a current traveling vehicle travels at the speed larger than the preset safety speed, the current traveling vehicle judges whether an obstacle located at the position smaller than the preset safety distance exists at the front or not, if yes, an accelerator limiting stopper abuts against an accelerator pedal, and it is maintained that thrust in the lifting direction is applied to the accelerator pedal; accident alarming information is sent backwards, a first rear vehicle judges whether the distance between the first rear vehicle and the current traveling vehicle is smaller than the preset safety distance or not after receiving the accident alarming information, if yes, the accelerator limiting stopper abuts against the accelerator pedal, and it is maintained that thrust in the lifting direction is applied to the accelerator pedal; and the first rear vehicle sends the accident alarming information to a second rear vehicle located behind, the second rear vehicle judges whether the distance between the second rear vehicle and the first rear vehicle is smaller than the preset safety distance or not after receiving the accident alarming information, if yes, the accelerator limiting stopper abuts against the accelerator pedal, it is maintained that thrust in the lifting direction is applied to the accelerator pedal, and the collision preventing effect of the traveling vehicle is achieved.

Description

technical field [0001] The invention relates to the field of automobile safety, and more specifically, relates to a method for avoiding collisions of running vehicles. Background technique [0002] The distance measurement between vehicles in the prior art adopts an active distance acquisition method, such as sending infrared rays or ultrasonic waves, and receiving reflected infrared rays or ultrasonic waves, and then completing the distance measurement. [0003] For example, Chinese invention patent application 201310224379.X discloses a driving safety automatic monitoring system, including a driving distance monitoring module for real-time monitoring of the distance of the vehicle ahead, wherein the driving distance monitoring module includes a central controller, and the input terminal of the central controller The connected ultrasonic receiving module and the ultrasonic transmitting module connected with the output end of the central controller, and the driving distance ...

AI Technical Summary

Problems solved by technology

[0005] When the ultrasonic waves are transmitted and received in a certain range or orientation, since the vehicle cannot keep facing the front vehicle all the time, when the vehicle changes direction, it is easy to receive the ultrasonic waves reflected from the side lane; when driving in the When on the lane near the green belt, it is easy to be affected by the green belt, and the ultrasonic reflection will be added back; and these situations will cause the above-mentioned invention to produce wrong judgment results during the implementation process

If all detected objects are displayed and then recognized, the implementation cost is high, the algorithm is complex, and the hardware requirements are high

Moreover, when the detection distance is less than the safety distance, it will not actively slow down or limit the speed of the vehicle, and does not provide further safety protection for the vehicle.
