Abstract

The invention relates to the technical field of automobile braking energy recovery, in particular to an automobile braking energy recovery method. The method comprises the steps that the vehicle speedand the brake master cylinder pressure of a vehicle are obtained; acquiring a required braking torque according to the vehicle speed and the pressure of a braking main cylinder, and judging a brakingstage of the vehicle, wherein the braking stage comprises a braking initial stage, a braking main stage and a braking end stage; when the vehicle is in the initial braking stage, the required brakingtorque is distributed to a motor, and a hydraulic braking system does not participate in braking; when the vehicle is in a main braking stage, the required braking torque is distributed to a hydraulic braking system and a motor; and when the vehicle is in the braking end stage, the required braking torque is distributed to a hydraulic braking system, and a motor does not participate in braking. The method can solve the problems that an existing electric vehicle braking energy recovery method is poor in braking pedal feeling, and the driving feeling is affected.

Description

technical field [0001] The invention relates to the technical field of vehicle braking energy recovery, in particular to a method for recovering vehicle braking energy. Background technique [0002] The cruising range has become the main technical bottleneck restricting the development of electric vehicles, and braking energy recovery can convert the kinetic energy during braking into electrical energy and re-store it in the battery, which can effectively improve the cruising range of electric vehicles. [0003] At present, most electric vehicles use signals such as master cylinder pressure and vehicle speed as the determination of the energy recovery target value, and then the vehicle controller performs motor energy recovery control according to the energy recovery target value. [0004] The existing vehicle kinetic energy recovery method includes: obtaining the current pressure value of the master cylinder brake fluid and the current rotation speed value of the wheel when...
