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. In response to a malfunction of the first and/or the second braking circuits the valve unit is switchable from a first position in which it connects the valve assembly of the first and second braking circuits to the brake booster, into a second position in which it connects the valve assembly of the third and fourth braking circuits to the brake booster.

Abstract: A braking system in an at least partially autonomous vehicle, having one vehicle wheel brake per vehicle wheel and having a primary brake regulation system and a redundant secondary brake regulation system. One hydraulic actuator for actuating the vehicle brake is provided per vehicle wheel in a first vehicle axle which actuator is assigned to both the primary brake regulation system and also the secondary brake regulation system. One electromechanical primary actuator per vehicle wheel is assigned to the primary brake regulation system in the second vehicle axle and one electromechanical secondary actuator is assigned to the secondary brake regulation system.

Abstract: A method for influencing the direction of travel of motor vehicles. The motor vehicle has a first steering system, having at least one steering axle with at least two wheels. The wheels are connected to the steering axle through wheel suspensions that can be adjusted by actuators. A redundant steering system is realized by adjusting a steering roll radius of at least one of the steering axles, according to which a force component acting orthogonally to the direction of travel in the region of at least one wheel is applied to the first steering system.

Abstract: A brake system for a motor vehicle has at least a first wheel brake and at least a second wheel brake. A first inlet valve is fluidically connected, on the one hand, to the first wheel brake, and, on the other hand, to a brake pressure source, and a second inlet valve is fluidically connected, on the one hand, to the second wheel brake, and, on the other hand, to the brake pressure source. In this case, a switching valve is provided, which fluidically connects the one fluid outlet of the second inlet valve in a first switching position to the second wheel brake and in a second switching position to the first wheel brake.

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 method for determining potential damage to a vehicle battery. In the method, at least one acceleration data set relating to a vertical acceleration of a motor vehicle, which includes the vehicle battery, is determined. The at least one acceleration data set is then checked for the presence of a predetermined damage criterion, which indicates the potential damage to the vehicle battery. Finally, only for the case that the damage criterion is determined in the at least one acceleration data set, a control signal for actuating an actuator device of the motor vehicle is generated.

Abstract: A method for adjusting a zero position of a brake pedal of a brake system of a motor vehicle. A separating valve arranged at least between a main brake cylinder and the respective wheel brakes of the brake system is opened in order to reduce a volume of the brake fluid in a secondary circuit of the brake system. At least one separating valve is then closed again after the volume of the brake fluid of the secondary circuit has been reduced by the predetermined volume amount, and the brake pedal is moved to a new zero position.
