Abstract

The invention relates to the field of electric vehicle control, in particular to a pure electric vehicle energy recovery torque exit slope control method. The invention provides the pure electric vehicle energy recovery torque exit slope control method, aiming at solving the problems that the pure electric vehicle cannot quit quickly under the conditions of impact pause, power lag and emergency in the energy recovery quit process. Firstly, the current driving working condition of the vehicle is judged by monitoring the opening degree of a brake and accelerator pedal, the vehicle speed and the wheel speed of the whole vehicle, the current state of each chassis component and the like, the energy recovery torque descending slope is independently adjusted according to different working conditions, and therefore the balance of economical efficiency, comfort and safety is achieved.

Description

technical field [0001] The invention relates to the field of electric vehicle control, in particular to a method for controlling the exit slope of the energy recovery torque of a pure electric vehicle. Background technique [0002] With the rapid development of new energy vehicles, reducing vehicle power consumption, increasing cruising range, and improving driving performance and safety have become the main development direction of pure electric vehicles in the future. Current pure electric vehicles are equipped with an energy recovery system, that is, the motor applies reverse torque to generate electricity during the process of gliding and braking, and converts kinetic energy into electrical energy to charge the battery to realize the recovery of kinetic energy during gliding and braking. [0003] When the driver releases the brake pedal, depresses the accelerator pedal, or the vehicle experiences abnormal conditions such as tire slippage, the energy recovery system will ...
