Abstract

The invention provides an energy recovery control method and system and a vehicle, the vehicle comprises a motor, the method comprises the steps of in the energy recovery process of the motor, obtaining the current vehicle speed and the current wheel speed of the vehicle, and determining the wheel slip rate according to the current vehicle speed and the current wheel speed; and adjusting the actual energy recovery torque of the motor according to the wheel slip rate. In the process of controlling the motor to conduct energy recovery, the wheel slip rate is considered at the same time, the actual energy recovery torque of the motor can be dynamically adjusted according to the wheel slip rate, the situation that wheels are locked due to the fact that the energy recovery torque is too large can be avoided, and the vehicle braking performance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an energy recovery control method, system and vehicle. Background technique [0002] At present, with the increasingly serious global environmental protection issues, new energy vehicles have developed rapidly. [0003] Compared with traditional cars, electric motors are added to new energy vehicles. The motor can be used not only to drive the vehicle, but also to turn on the energy recovery function when the vehicle is decelerating, so that the motor generates power to generate torque in the opposite direction to decelerate the vehicle, and at the same time realize the recovery of vehicle kinetic energy and prolong the driving range of the vehicle. . [0004] At this stage, most vehicles including new energy vehicles are equipped with anti-lock braking system (Anti-lockBraking System, ABS), which can prevent the wheels from Locking, so as to ensure the braking performance...
