Abstract: The invention relates to a motor vehicle comprising: a number of wheels; a brake system having hydraulically actuatable brakes corresponding to each wheel; at least one brake circuit via which the brakes can be actuated; a brake booster via which the brake circuit can be operated, said brake booster being actuatable via a brake pedal to be actuated by the driver; and at least one pressure generation device and/or pressure accumulator device, which can be controlled by a control device, and via which the hydraulic pressure inside the brake circuit can be modulated. At least one electric motor (9) is provided, which motor is used in the event of a detected failure inside the brake system (2) to generate a deceleration torque by automatically switching into a generator operation, in order to brake the vehicle (1) until same has reached a standstill.

Abstract: A motor vehicle includes a first and a second set of two separate hydraulic braking circuits. Each of the two braking circuits of each of the first and second set includes a valve assembly for modulating a braking pressure in the two separate hydraulic braking circuits. A valve unit is arranged downstream of a brake booster and is switchable in response to a malfunction of one or both of the two braking circuits of the first set from a first position in which it connects the valve assembly of the two separate hydraulic braking circuits of the first set to the brake booster, into a second position in which it connects the valve assembly of the two separate hydraulic braking circuits of the second set to the brake booster.

Abstract: A motor vehicle includes a plurality of wheels and a brake system, which has brakes, which can be hydraulically actuated and are each associated with a wheel. The brakes can be actuated by at least one brake circuit which can be operated by a brake booster. The brake booster can be actuated by a brake pedal to be pressed by the driver. At least one pressure-generating and/or pressure-accumulating device, controlled by a control device to modulate the hydraulic pressure within the brake circuit. A second pressure-generating and/or pressure-accumulating device is provided in the brake circuit to automatically increase the pressure within the brake circuit in dependence on demand independently of the first pressure-generating and/or pressure-accumulating device, when a malfunction is detected in the brake system.

Abstract: A motor vehicle includes multiple wheels, each having at least one assigned hydraulically actuatable brake; first and second separate hydraulic braking circuits each including multiple valves for modulating a braking pressure in the two separate hydraulic braking circuits, the multiple valves forming a valve assembly; a first control device controlling the multiple valves; third and fourth separate hydraulic braking circuits and a second control device respectively of same construction as the first and second braking circuits and the first control device; a brake booster, operably connectable to the two separate hydraulic braking circuits and the two further separate hydraulic braking circuits; and a valve unit arranged downstream of the brake booster.
