Braking control device for electric vehicle, has controller that regulates linear valve to generate differential pressure based on hydraulic pressure corresponding to regenerative braking power

摘要

The device has a controller (9) that regulates a linear valve (27) to generate differential pressure based on the hydraulic pressure corresponding to the regenerative braking power. The linear valve is placed in a fluid passage linked to a wheel cylinder (25) from the motor (15), pump (17) and accumulator (19). The motor, pump and accumulator are used to generate hydraulic brake pressure equal to the hydraulic pressure generated using a master cylinder (13). Another wheel cylinder (23) is connected to the master cylinder. The driving wheel of an electric vehicle is operated using the regenerative braking power generated using the battery (1), controller, and motor.
