Abstract

The invention discloses an electric vehicle braking system (EVBS) capable of reclaiming braking energy. The EVBS comprises a hydraulic braking subsystem, a braking energy reclaiming subsystem and a whole vehicle controller. The hydraulic braking subsystem comprises a braking pedal, a vacuum booster, a braking main cylinder, an oil storage chamber, an EVBS hydraulic unit, and an EVBS electric control unit for controlling the operation of the EVBS hydraulic unit; the braking energy reclaiming subsystem comprises a storage battery, a reversible motor controller, a motor, a transmission and a main speed reducer; and the whole vehicle controller is respectively connected with the EVBS electric control unit and the reversible motor controller. According to the system, a hydraulic brake and a motor reclaiming brake are coordinated; the whole vehicle controller cooperatively controls the reversible motor controller and the EVBS electric control unit, so that the braking safety is ensured; when the motor reclaiming brake fails, the hydraulic braking system can still work reliably; the whole hydraulic unit has a simple structure and is easy for batch production; and the EVBS has a consistent braking effect in a reclaiming or non-reclaiming state, and has the same braking sensation.

Description

technical field [0001] The invention relates to an electric vehicle braking system, in particular to an electric vehicle braking system capable of recovering braking energy. Background technique [0002] The sustainable development of the automobile industry is facing the dual pressure of energy and environmental protection. For this reason, countries around the world are vigorously developing electric vehicles with zero emissions and zero pollution. However, the mileage of electric vehicles on one charge is far less than that of traditional fuel vehicles, which seriously affects the industrialization and rapid promotion of electric vehicles. [0003] The energy consumed in the braking process of automobiles running in urban areas sometimes exceeds 40%-50% of the total energy consumption of automobiles. Braking energy recovery is an important energy-saving measure for automobiles. Compared with traditional internal combustion engine vehicles, various forms of electric vehic...
