A vehicle driving safety control system

Abstract

The invention relates to the technical field of automobile braking, in particular to a vehicle driving safety control system. The system comprises a controller, a hill-start backward sliding prevention control system, a driving emergency brake control system, a reverse tooth gear shaft sleeving an automobile transmission shaft and reverse teeth on the reverse tooth gear shaft, wherein the hill-start backward sliding prevention control system comprises a backward sliding prevention switch, a first-gear switch, a gradient sensor and a backward sliding prevention electromagnetic valve; when the condition is met, the controller electrifies the electromagnetic valve, armature pusher rods moves downwards to press a lock rod to press against the reverse teeth and prevent the transmission shaft from rotating anticlockwise; the driving emergency brake control system comprises a pedal position sensor, a pusher rod extreme position switch, a reverse switch, a wheel speed sensor and an emergency brake electromagnetic valve; during electrification under the condition, the two armature pusher rods press the reverse teeth from the two sides to prevent the transmission shaft from rotating clockwise and anticlockwise. The vehicle driving safety control system has functions of prevention of a vehicle from sliding backwards and automatic emergency braking, so that the safety of the vehicle can be improved, and vehicle accidents are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a vehicle driving safety control system. Background technique [0002] Cars will encounter various situations during driving, such as starting on an uphill section and failure of service brakes. In these special situations, improper handling can easily lead to vehicle accidents and endanger personal safety. When starting uphill, if the operation is improper, the car may slip backwards, especially under heavy load, when the hand brake performance is not good. In order to avoid this from happening, it is necessary to constantly practice the driving skills of the car starting on a hill. Under normal circumstances, the hand brake, clutch and accelerator should be well coordinated when starting, so that the car can start without slipping; Difficulty is greater, the right foot has to step on the brake and also step on the gas pedal, it is difficult to control, especially t...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the hand brake, clutch and accelerator should be well coordinated when starting, so that the car can start without slipping; Difficulties are greater, the right foot has to step on both the brake and the accelerator, it is difficult to control, especially the driver with insufficient driving experience is likely to be in a hurry, and traffic accidents are likely to occur at this time

In addition, some drivers used the brake improperly and controlled improperly when going down a long slope, and the brakes failed due to flameout and coasting, causing the vehicle to lose control and lead to tragedy.

At present, the hand brake and foot brake set on tractors and transport vehicles all act on the brakes. When the brakes fail or the air pressure is insufficient, the car has no other backup emergency braking system, which is not conducive to safety.
