An iso/dump control valve arrangement is associated with each wheel brake of the plurality of wheel brakes. A pump piston is associated with at least one wheel brake of the plurality of wheel brakes. The pump piston is driven by a second electric motor for selectively providing pressurized hydraulic fluid to the iso/dump control valve arrangement. At least one electric brake motor is operative to selectively drive a selected wheel brake. A first electronic control unit is operative to selectively control the first electric motor. A second electronic control unit is operative to selectively control the second electric motor. A third electronic control unit is operative to control the at least one electric brake motor.

First and second power transmission units are configured for selectively providing pressurized hydraulic fluid during a braking event. The first power transmission unit actuates a selected one of the front wheel brakes and a selected one of the rear wheel brakes. The second power transmission unit actuates the other one of the front wheel brakes and the other one of the rear wheel brakes. First and second electronic control units control the first and second power transmission units. A pair of rear brake motors selectively electrically actuate rear wheel brakes. Multiplex control of each of the pairs of front and rear wheel brakes is provided by an arrangement of first and second parallel valves for each wheel brake.

摘要： A brake monitoring system monitors pressures in a brake system of a vehicle system at different locations in the vehicle system. Decreases in the pressures are determined at two or more of the different locations. The times at which the decreases in the pressures occurred are determined. A location of interest of a leak in the brake system is determined by comparing the times at which the decreases in the pressures occurred.

摘要： Disclosed is an electronic brake system. The electronic brake system according to the present embodiment comprises: a first block in which a mechanical part that is mechanically operated and linked with a brake pedal is disposed; a second block in which an electronic part electronically operated and controlled by an electronic control unit is disposed; and a connection line which hydraulically connects the first block and the second block. The first block and the second block can be installed at positions spaced apart from each other in a vehicle, and thus the mountability of the brake system and the degree of freedom in designing the vehicle can be improved.

摘要： A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.

摘要： In one embodiment, a system determines activation parameters for an autonomous driving vehicle (ADV), where the activation parameters include historical usages of a primary brake system or a secondary brake system. In response to determining that a brake is to be applied, the system determines whether to activate a primary or a secondary brake system based on the activation parameters. The system sends an activation flag to activate the primary or the secondary brake system based on the determining whether to activate the primary or the secondary brake system. The system sends a brake command to the primary and the secondary brake system to activate either the primary or the secondary brake system according to the activation flag.
