Abstract

The invention discloses an unmanned vehicle brake control method, a control system and a vehicle. The brake control method comprises the following steps of acquiring vehicle condition and road condition information of the vehicle; acquiring a brake pressure distribution model; determining first brake pressure and second brake pressure according to the vehicle condition and road condition information and the brake pressure distribution model; and driving a front axle braking device to carry out braking control over front wheels according to the first brake pressure, and driving a rear axle braking device to carry out braking control over rear wheels according to the second brake pressure. According to the brake control method provided by the embodiment of the invention, the brake pressure distribution of the front axle and the rear axle can be customized according to the vehicle condition and road condition information; and a problem that brake pressure configuration is unreasonable issolved, brake nodding and rollover accidents caused by braking are avoided, a braking posture of a vehicle body is stable, the service life of the whole vehicle braking device can be prolonged, in addition, the braking problem under a part of extreme working conditions can be solved, and braking reliability and driving safety can be improved.

Description

technical field [0001] The invention relates to the technical field of braking control, in particular to a braking control method, control system and vehicle of an unmanned vehicle. Background technique [0002] With the development of unmanned driving technology, unmanned vehicles have been more and more widely used in logistics transportation, ferry transportation, emergency rescue and other fields. [0003] At present, the braking scheme of unmanned vehicles mainly adopts the traditional hydraulic braking scheme or the pneumatic braking scheme. Among them, the traditional hydraulic braking scheme usually has a brake master cylinder, and the brake master cylinder is connected to each hydraulic pressure through a hydraulic circuit. The brakes control the action of the brake master cylinder by collecting brake pedal signals, and adjust the braking pressure of each hydraulic brake; The device is connected to each pneumatic brake through a pneumatic circuit, and the action of...
