Abstract
A brake system of a vehicle with a regenerative braking function, such as a hybrid electric vehicle. A regenerative braking hydraulic pressure line connects a master cylinder with a wheel cylinder. A regenerative control valve opens and closes the regenerative braking hydraulic pressure line. A proportional control valve is disposed in the regenerative braking hydraulic pressure line. The proportional control valve includes a spool, and output characteristics of the proportional control valve vary in response to an amount of pressure applied to the spool. A spool operator changes the amount of pressure applied to the spool.
Claims3
A brake system, comprising:
- a regenerative braking hydraulic pressure line that connects a master cylinder with a wheel cylinder;
