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 shunting auxiliary braking system and an anti-collision shunting auxiliary braking method for heavy-duty vehicle on a long downhill road section. Through judging traffic flow conditions of the long downhill road section by means of a radar, the heavy-duty vehicle can be subjected to shunting guidance according to the traffic flow conditions of the road, thus the heavy-duty vehicle goes downhill separately from common vehicles, and auxiliary braking is performed on the heavy-duty vehicle. By using a communication network for data transmission, line useis reduced, the anti-collision shunting auxiliary braking system is good in universality, and a lane changing distance is reserved to facilitate lane changing of vehicles. A display screen is locatedon a horizontal road section, has a certain distance from the slope top and has a certain distance from a weighing sensor, thus a driver can observe prompt information conveniently, and sufficient time is provided for lane changing.

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...
