摘要: A brake system for a motor vehicle comprises a normally closed circuit separation valve such that the system is configured to operate in 1) in a by-wire mode when the circuit separation valve is open, such that pressure only from a pressure chamber of a linear actuator is delivered to both first and second pairs of wheel brakes, and 2) in a circuit separation mode with the circuit separation valve in the normally closed position, such that pressure from a tandem master cylinder is delivered only to the first pair of wheel brakes, and such that pressure from the pressure chamber of the linear actuator is concurrently delivered only to the second pair of wheel brakes. The system can provide braking pressure even in the event of a by-wire braking module leak that causes inoperability of an ECU.

摘要: Vehicles according to at least some embodiments of the disclosure include a sensor, and a computing device comprising at least one hardware processing unit. The computing device is programmed to perform operations comprising capturing an image with the sensor, identifying an object in the image, and in response to an accuracy of the identification meeting a first criterion, pre-loading a braking system of the autonomous vehicle. In some aspects, the computing device may predict that an object not currently within a path of the vehicle has a probability of entering the path of the vehicle that meets a second criterion. When the probability of entering the path meets the second criterion, some of the disclosed embodiments may pre-load the braking system.

摘要: An electric brake booster for an autonomous vehicle is provided. The electric brake booster includes a body part that receives a power cylinder generating braking pressure in an autonomous driving/braking mode and a master cylinder generating braking pressure in a manual driver braking mode. A driving shaft is movable in an axial direction in the power cylinder and coupled to a piston. A first motor is connected to a first side of the driving shaft and provides driving power thereto. A second motor is connected to a second side of the driving shaft and provides driving power thereto in a direction equal to that of the driving power provided from the first motor. A controller determines whether the first or second motor normally operates and simultaneously or separately operates the first and second motors based on a magnitude of the pressure in the power cylinder or whether emergency braking occurs.
