Abstract

The invention discloses a redundant braking control method, device and system, a vehicle and a storage medium. The method comprises the following steps that the deceleration torque of a vehicle motoris determined according to the initial speed and the initial acceleration of the vehicle; the vehicle motor is controlled to enable the vehicle to decelerate according to the deceleration torque; whenthe current vehicle speed of the vehicle is less than or equal to the threshold speed, the braking pressure of a vacuum booster of the vehicle is determined according to the current vehicle speed anda preset vehicle speed pressure association table; and the vacuum booster is controlled to enable the vehicle to decelerate according to the braking pressure. According to the method provided by theembodiment, the braking control under redundant braking of the vehicle is realized, the stability of the vehicle can be improved, the instability of the vehicle is prevented, and the comfort of vehicle driving is improved.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of automatic control, and in particular to a redundant braking control method, device, system, vehicle and storage medium. Background technique

[0002] With the market share of electric vehicles increasing year by year, the related technologies of electric vehicles have developed rapidly. In the field of electric vehicles, the redundant braking system of electric vehicles is responsible for receiving the braking command sent by the upper automatic driving controller through the vehicle bus to realize the braking of the vehicle. Braking, the safety and stability of the redundant braking system of electric vehicles has become an important guarantee for vehicle safety.

[0003] In the existing technology, the redundant braking system of electric vehicles is mainly realized by hydraulic active braking, which cannot fully guarantee the safety when the braking fails. However, the mechani...
