Abstract

The invention relates to a brake control method and device, and relates to the technical field of control. The method comprises the steps of obtaining running speed of a vehicle, and when the runningspeed is smaller than or equal to the preset first threshold value, determining a brake mode of the vehicle, wherein the brake mode comprises a feedback brake mode and a non-feedback brake mode; whenthe brake mode is the feedback brake mode, reducing the feedback brake torque of the vehicle so as to enable the running speed of the vehicle to be decreased to the preset second threshold value, andenabling the vehicle feedback brake torque to be zero. On the premise of ensuring comfort of vehicle parking, the vehicle energy recycling efficiency is improved, and the duration time is prolonged.

Description

technical field [0001] The present disclosure relates to the technical field of control, and in particular, to a brake control method and device. Background technique [0002] With the rapid development of society, the number of automobiles keeps increasing, and automobiles using traditional energy sources will pollute the environment due to the exhaust gas produced by burning petroleum fuels. At the same time, the problem of non-renewable traditional energy sources is becoming more and more serious, so vigorously develop New energy has become an inevitable trend, and electric vehicles and hybrid vehicles using environmentally friendly new energy have become a major trend in the development of automotive technology. In electric vehicles and hybrid vehicles, the drive motor can also provide braking force for the vehicle when the vehicle is decelerating, so the motor regenerative braking system and the traditional air braking system together form a composite braking system. ...
