Abstract

The invention discloses a pure electric vehicle braking energy recovery control system and method based on a DCT (Data Communication Terminal), relating to the technical field of electric vehicles. The control system comprises a vehicle-mounted storage battery, a motor, a two-gear DCT automatic gearbox, a vehicle speed sensor, a master cylinder pressure sensor, a vehicle control unit, a battery management system, a motor controller, a gearbox controller and a feedback type brake anti-lock system, wherein the vehicle-mounted storage battery supplies power for the motor, and the motor is mechanically connected with the DCT automatic gearbox; and the vehicle control unit, the battery management system, the motor controller, the gearbox controller, the feedback type brake anti-lock system, the vehicle speed sensor and the master cylinder pressure sensor carry out information communication and instruction issue through a network and hard wires. The invention also discloses the pure electric vehicle braking energy recovery control method based on the DCT. The energy utilization and the driving mileage of the vehicles are increased.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a DCT-based braking energy recovery control system and method for pure electric vehicles. Background technique [0002] Foreign pure electric vehicle solutions mostly focus on single-stage deceleration, which fully realizes the speed regulation function requirements through the motor, and covers the power requirements of the whole vehicle under all working conditions through the low-speed constant torque and high-speed constant power characteristics of the motor. However, due to the gap in the manufacturing technology of domestic motors, it is difficult to reach a maximum speed of more than 10,000 rpm, which limits the power level of pure electric vehicles and puts forward higher requirements for the high-efficiency range of the motor. Therefore, a single-stage deceleration is adopted. It is difficult to obtain good power and economy. [0003] In the development of pur...
