摘要: A vehicle brake system includes a brake pedal unit (BPU) coupled to a vehicle brake pedal and including an input piston connected to operate a pedal simulator during a normal braking mode, and coupled to actuate a pair of output pistons during a manual push through mode. The output pistons are operable to generate brake actuating pressure at first and second outputs of the BPU. A hydraulic pressure source for supplying fluid at a controlled boost pressure is included. The system further includes a hydraulic control unit (HCU) adapted to be hydraulically connected to the BPU and the hydraulic pressure source, the HCU including a slip control valve arrangement, and a switching base brake valve arrangement for switching the brake system between the normal braking mode wherein boost pressure from the pressure source is supplied to first and second vehicle brakes, and the manual push through mode wherein brake actuating pressure from the BPU is supplied to the first and second vehicle brakes.

摘要: A brake system for actuating a pair of front wheel brakes and a pair of second wheel brakes. The brake system includes a reservoir and a brake pedal unit having a housing with first and second pistons slidably disposed in the housing. The first and second pistons are operable during a manual push-through mode by actuation of a brake pedal connected to the brake pedal unit. The first and second pistons are movable to generate brake actuating pressure at first and second outputs for actuating the pair of front wheel brakes and the pair of rear wheel brakes. A first source of pressurized fluid actuates the pair of front wheel brakes and the pair of rear wheel brakes during a non-failure normal braking event. A first electronic control unit controls the first source of pressurized fluid. A second source of pressurized fluid is hydraulically connected to the brake pedal unit and actuates the brake pedal unit to cause movement of the first and second pistons for generating pressure at the first and second outputs. A second electronic control unit, separate from the first electronic control unit, controls the second source of pressurized fluid.

摘要: A pump attenuator bypass valve (40/100/200) is located at an outlet of a pump (30) in a vehicle braking system (10) between the pump (30) and an attenuator (34). The attenuator bypass valve (40/100/200) includes a bypass valve housing (41), a first fluid flow path (74, 57/179/220, 208), and a second fluid flow path (80/183). The first fluid flow path (74, 57/179/220, 208) is defined in the housing (41) and is configured to allow continuous flow of fluid when the pump (30) operates at a first pump flow rate. The second fluid flow path (80/183) is defined in the housing (41) and is configured to bypass the first fluid flow path (74, 57/179/220, 208) and to allow continuous flow of fluid when the pump (30) operates at a second pump flow rate higher than the first pump flow rate.

摘要: A brake pedal unit for coupling to a brake pedal includes a housing and a pedal simulator housed within a simulation chamber formed in the housing. The pedal simulator includes a spring for providing force feedback. A first piston is mounted in the housing. The first piston is operable to generate brake actuating pressure at a first pressure output. A second piston is mounted in the housing. The first piston is operable to generate brake actuating pressure at a second pressure output. An input piston is connected to operate the pedal simulator during a normal braking mode, and wherein the input piston is coupled to actuate the first and second pistons during a manual push-though mode.

摘要: A brake system includes first and second wheel brakes, a reservoir, and a brake pedal unit having a housing and a pair of output pistons slidably disposed in the housing. The output pistons generate brake actuating pressure during a manual push-through mode for actuating the first and second wheel brakes. The system further includes a plunger assembly having a housing having first and second ports, a motor driving an actuator, and a piston connected to the actuator. The piston pressurizes a first chamber when the piston is moving in a first direction to provide fluid flow out of the first port. The piston pressurizes a second chamber when the piston is moving in a second direction opposite the first direction to provide fluid flow out of the second port. The first and second ports are selectively in fluid communication with the wheel brakes.

摘要: A brake system includes a plunger assembly for actuating wheel brakes during a normal brake apply. The plunger assembly includes a motor mounted on the housing for driving an actuator. A first piston is connected to the actuator. The first piston is slidably mounted within the housing for pressurizing a first fluid chamber in the housing. A second piston is slidably mounted within the housing for pressurizing a second fluid chamber in the housing. A pump-less control valve arrangement includes a first control valve regulating the flow of fluid between a first fluid chamber and the first wheel brake. A second control valve regulates the flow of fluid between a second fluid chamber and the second wheel brake. An isolation valve arrangement switches the brake system between the normal braking mode and the manual push-through mode.
