Abstract

The invention discloses a braking energy recovery method, a braking energy recovery device and a vehicle. The braking energy recovery method comprises the steps of obtaining obstacle information in front of a vehicle and vehicle state information, and the vehicle state information comprising the accelerator pedal state and the speed of the vehicle; determining the braking intention of a driver according to the obstacle information and the accelerator pedal state; distributing hydraulic braking force and / or motor braking force according to the braking intention, the obstacle information and thespeed of the vehicle; and acquiring the current residual electric quantity information of a battery, and recovering the braking energy according to the residual electric quantity information and thedistribution result of the hydraulic braking force and the motor braking force. According to the braking energy recovery method, the braking energy recovery device and the vehicle, the braking energyrecovery efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of braking energy recovery, and in particular to a braking energy recovery method, a braking energy recovery device and a vehicle. Background technique [0002] With the development of vehicle electrification, how to improve the cruising range of electric vehicles has become an important issue. At present, the energy recovery of the braking system is an important method that can effectively improve the cruising range. [0003] In the prior art, the braking energy recovery is usually performed after the driver steps on the brake pedal, and the braking energy recovery efficiency is low. Contents of the invention [0004] The invention provides a braking energy recovery method, a braking energy recovery device and a vehicle to improve the braking energy recovery efficiency. [0005] In a first aspect, an embodiment of the present invention provides a braking energy recovery method f...
