Abstract

The invention discloses a braking control method, device and equipment of an electric vehicle and a storage medium. The method comprises the steps that running data of the vehicle are obtained in real time; when the vehicle runs in the hydraulic compensation mode, the corresponding whole vehicle required recovery torque is obtained based on the current pedal opening degree, the real-time vehicle speed and the sliding recovery strength of the vehicle; a corresponding available torque of the battery is obtained based on the charging power of the power battery; the hydraulic compensation demand torque of the vehicle is determined according to the relation among the whole vehicle demand recovery torque, the battery available torque and the motor recovery torque; and the brake master cylinder of the vehicle is controlled to conduct hydraulic loading at the speed matched with the hydraulic compensation demand torque, so that braking of the vehicle is achieved. According to the braking control method, device and equipment of the electric vehicle and the storage medium, when the vehicle decelerates, compensation is provided for the braking energy recovery system by calculating the hydraulic demand torque, and therefore normal deceleration of the vehicle is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, in particular to a braking control method, device, equipment and storage medium for electric vehicles. Background technique [0002] With the continuous development of new energy technologies, electric vehicles or hybrid vehicles are gradually recognized by the market and favored by consumers due to their advantages such as quick start, zero emission, low noise, and low energy consumption. [0003] When a traditional fuel vehicle is decelerating, the wheel brakes apply braking force to the wheels, and the kinetic energy of the vehicle is converted into heat energy through braking and released into the air to achieve vehicle deceleration. For electric vehicles or hybrid vehicles , This kinetic energy wasted due to braking can be converted into electrical energy and re-stored in the power battery of the electric vehicle through coasting energy recovery technology, thereby improvin...
