Problems solved by technology

Among them, the rear-end collision accident caused by the continuous brake failure of the heavy-duty vehicle on the long downhill section caused serious damage.
[0003] The reason why the brakes of heavy-duty vehicles fail is the long-term high-intensity braking, which causes the brake heat to fade. It will rise quickly, the friction coefficient of the brake friction pair will decrease, the braking torque will decrease, the braking deceleration will decrease, the heat of the brake will decline, and the braking efficiency will decrease

Abstract

The invention discloses an anti-collision diversion auxiliary braking system and method for heavy-duty vehicles on a long downhill road section. The traffic flow situation of the long downhill road section is judged by radar, and the heavy-duty vehicle is diverted and guided according to the traffic flow situation of the road. Ordinary vehicles separate downhill and apply auxiliary braking to them. The communication network is used for data transmission to reduce the use of lines. The system has good versatility and leaves a lane-changing distance for vehicles to change lanes. The position of the display screen is located at a certain distance from the top of the slope on the horizontal road section, and a certain distance from the load cell, which is convenient for the driver to observe the prompt information and have enough time to change lanes.

Description

technical field [0001] The invention belongs to the technical field of vehicle anti-collision on long downhill sections, and in particular relates to an anti-collision diversion auxiliary braking system and method for long downhill sections of heavy-duty vehicles. Background technique [0002] With the rapid development of expressway construction in the mountainous areas of western my country, there are more and more dangerous road sections with long downhill slopes, and the problem of driving safety has become increasingly prominent. Among them, the rear-end collision accident caused by the continuous brake failure of the heavy-duty vehicle on the long downhill section caused serious damage. [0003] The reason why the brakes of heavy-duty vehicles fail is the long-term high-intensity braking, which causes the brake heat to fade. It will rise quickly, the friction coefficient of the brake friction pair will decrease, the braking torque will decrease, the braking decelerati...
