The main cylinder vacuum booster assembly comprises a braking pedal, an oil pot (5) and a braking main cylinder. An opening N of the braking main cylinder is connected with a pipe of an opening p of a left back wheel oil inlet electromagnetic valve of the ABS hydraulic control unit, an opening p of a normally-open electromagnetic valve of the braking energy recovery hydraulic control unit is connected with an opening M of the braking main cylinder through a pipe, an opening a of the normally-open electromagnetic valve and an opening p of a normally-closed linear electromagnetic valve are connected with an opening p of a right front liquid inlet electromagnetic valve of the ABS hydraulic control unit through a pipe, an opening a of the normally-closed linear electromagnetic valve is connected with the oil pot (5) through a pipe, and the electronic control device and the braking energy recovery hydraulic control unit are connected with the ABS hydraulic control unit through pipes.

Description

technical field [0001] The invention relates to a hydraulic device in the field of automobile braking systems, more precisely, the invention relates to a hydraulic device applied to the recovery of braking energy of automobiles. Background technique [0002] When the new energy vehicle decelerates or brakes, the motor can convert part of the mechanical energy of the car into electrical energy and store it in the battery, and at the same time generate part of the braking force to realize the deceleration or braking of the car. When the car accelerates again, the motor will store it The energy stored in the battery is converted into kinetic energy for driving the car again. Therefore, the recovery of braking energy is an effective way for hybrid and pure electric vehicles to save fuel and reduce emissions. A hydraulic system and control method for efficient braking energy recovery suitable for new energy vehicles is very urgent. [0003] The research on the braking energy rec...
