Abstract

The invention discloses a braking control method, a control system and a vehicle for an unmanned vehicle. The braking control method comprises the following steps: acquiring vehicle condition and road condition information of the vehicle; acquiring a brake pressure distribution model; The pressure distribution model determines the first brake pressure and the second brake pressure; drives the front axle brake device to brake the front wheels according to the first brake pressure, and drives the rear axle brake device to brake the front wheels according to the second brake pressure Rear wheel brake control. The brake control method provided by the embodiment of the present invention can customize the brake pressure distribution of the front axle and the rear axle according to the vehicle condition and road condition information, which solves the problem of unreasonable brake pressure configuration and avoids brake nodding and In the event of a rollover accident, it ensures a stable braking posture of the vehicle body, which helps to prolong the service life of the vehicle's braking device. In addition, it can solve the braking problem under some extreme working conditions, which is conducive to improving braking reliability and driving safety.

Description

Unmanned vehicle braking control method, control system and vehicle technical field The present invention relates to the technical field of braking control, in particular to a kind of unmanned vehicle braking control method, control systems and vehicles. Background technique [0002] With the development of unmanned technology, unmanned vehicles are used in the fields of logistics transportation, ferrying passengers, and emergency rescue. has been more and more widely used. At present, the braking scheme of unmanned vehicle mainly adopts traditional hydraulic braking scheme or pneumatic braking method. In the traditional hydraulic braking scheme, a brake master cylinder is usually set, and the brake master cylinder is connected to each hydraulic circuit through a hydraulic circuit. Press the brake, control the action of the brake master cylinder by collecting the brake pedal signal, and adjust the braking pressure of each hydraulic brake; The working principle of t...
