Abstract
An actuator assembly for a vehicle brake system comprises a piston disposed in a bore, a reservoir, and a solenoid. A channel is in fluid communication between the bore and the reservoir, and the solenoid is disposed in the channel. The solenoid is movable between an open position and a closed position. In the closed position, the solenoid blocks fluid communication between the bore and the reservoir.
Claims20
An actuator assembly for a vehicle brake system, the actuator assembly comprising:
- a piston disposed in a bore;
- a reservoir;
- a channel in fluid communication between the bore and the reservoir;
- a two-way solenoid disposed in the channel, the solenoid being movable between an open position and a closed position, the solenoid in the closed position extending into the bore and blocking fluid communication between the bore and the reservoir;
- and
- a controller which receives sensed driver information and determines a signal to the solenoid.
An actuator assembly for a vehicle brake-by-wire system, the actuator assembly comprising:
- a piston disposed in a bore;
- a reservoir;
- a channel in fluid communication between the bore and the reservoir;
- a two-way solenoid disposed in the channel, the solenoid being movable between an open position and a closed position;
- and
- a controller, which receives sensed driver information, and determines a signal to move the solenoid to the closed position extending into the bore and blocking fluid communication between the bore and the reservoir.
An actuator assembly for a vehicle brake-by-wire system, the actuator assembly comprising:
- a piston disposed in a bore;
- a reservoir;
- a channel in fluid communication between the bore and the reservoir;
- a two-way solenoid disposed in the channel, the solenoid being movable between a normally open position and a closed position;
- and
- a controller for moving the solenoid to the closed position in response to a braking event, the solenoid in the closed position extending into the bore and blocking fluid communication between the bore and the reservoir, the controller receiving driver information including force applied to a pedal and travel of the pedal.
