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.

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.

A brake-by-wire brake system for a vehicle having at least two wheels which can be braked is specified. The brake system comprises at least two brake actuator units, which each have a brake actuator assigned to one of the wheels, which can be braked, for the purposes of braking the vehicle during driving operation. The brake system furthermore comprises a driver brake actuation unit for actuation by the driver for a braking operation, having at least one sensor for detecting an activation of the driver brake actuation unit by the driver, and at least one electronic control unit which is configured to activate one or both brake actuator units in order to impart a braking force to an associated wheel, wherein the driver brake actuation unit is coupled, for transmission of signals, to the at least one electronic control unit. The driver_brake actuation unit has an interface for a controller that is independent of the brake system. A vehicle having a brake system, and a method for operating a brake system, are also specified.

A brake system (BS) includes first/second electric-power-supply-units (EPSU), and an electronic-brake-control-unit (EBCU) connected to the first EPSU. The BS includes a first axle-pressure-modulator (APM) for service-brake-chambers for a first vehicle-axle (VA). The first APM is connected to the EBCU. The BS includes a second APM for spring-brake-cylinders for a second VA. The second APM is connected to the EBCU. The BS includes a redundant-brake-pedal-sensor (BPS) connected to the EBCU.
