Abstract: A method for operating a brake system and a brake system. The brake system includes a primary brake actuator and a secondary brake actuator. In the method, a brake pressure is adjusted using the primary brake actuator based on a first braking specification, and a brake pressure adjusted by the primary brake actuator is read in using a control unit of the secondary brake actuator or using an additional control unit. Then, using the control unit of the secondary brake actuator or using an additional control unit, a first plausibility check of the ascertained brake pressure is carried out with a second braking specification, which was supplied to the control unit of the secondary brake actuator or to the additional control unit.

Abstract: A method for operating a brake system of a motor vehicle, with a controllable brake booster, and with a brake pedal. In the method, the brake booster is controlled, as a function of an actuation of the brake pedal, to generate a hydraulic pressure in the brake system, the motor vehicle is monitored for a standstill of the motor vehicle, an actuation path of the brake pedal is monitored for an exceedance of a specified limit value, and a holding function for maintaining the hydraulic pressure present in the brake system is activated if a standstill and a limit value exceedance are detected. At least one state variable of the motor vehicle is ascertained and that the limit value is specified as a function of the at least one state variable.

Abstract: A communication method between a brake booster of a vehicle and an ESP control unit of the vehicle. In the method, a signal is coupled into a brake fluid, transported between the brake booster and the brake control unit over a brake line filled with the brake fluid, and extracted again from the brake fluid.

Abstract: A device and to a method for controlling a highly automated vehicle, as well as a portable unit for remotely controlling the highly automated vehicle, the highly automated vehicle being able to independently carry out driving maneuvers without the intervention of the driver or a vehicle occupant. The device for controlling is connected to the portable unit. The device for controlling receives a signal from the portable unit that the portable unit has detected a dropping by the vehicle driver or a vehicle occupant. Upon detection of a free fall, the presently independently carried out driving maneuver is automatically aborted or terminated.

Abstract: A method is for operating a braking system including a primary braking actuator having a first control apparatus. The primary braking actuator is operated based on a first braking specification. The braking system further includes a secondary braking actuator having a second control apparatus. The first control apparatus and the second control apparatus and/or a further control apparatus are connected to one another by a communication device. The second control apparatus and/or the further control apparatus checks whether signals from the first control apparatus are received in the second control apparatus and/or the further control apparatus, or whether the signals received from the first control apparatus in the second control apparatus and/or the further control apparatus are faulty. When there are no received signals or when there are faulty signals, operation of the secondary braking actuator is enabled or prevented based on a second braking specification.

Abstract: A method, and device for performing the method, of compensating electromagnetic interference on the output signal of a sensor, wherein a pre-determined singular number or a plurality of at least temporarily current-carrying electrical conductors in the vicinity of the sensor are classified as interference signal sources possibly influencing the output signal of the sensor, in which the output signal of the sensor is detected, and it is determined for each of these interference signal sources whether it is currently current-carrying. Either a fixed correction variable or a correction variable determined on the basis of the detected instantaneous current strength in the current-carrying conductor is detected for each current-carrying interference signal source. The output signal of the sensor is corrected based on the detected correction variables.

Abstract: A brake control device for a vehicle. The brake control device includes a control device, which can be connected to a brake booster device, to an electric machine of the vehicle, and to a driving stability system; a pedal sensor device, which is connected to the control device, wherein the control device is configured to infer, from the pressing of the brake pedal and/or the gas pedal, a braking request from a driver, to identify an operational failure or an operational fault of the brake booster device, and, if an operational failure or an operational fault of the brake booster device is identified after and/or upon a braking request, to control a braking action by means of the driving stability system.

Abstract: A method for ascertaining an available fluid volume in a tank for brake fluid of a braking system. The braking system includes a pressure generator fluidically connected to the tank on the one hand and to at least one brake circuit on the other hand, which is activatable for generating a hydraulic pressure in the braking system as brake fluid is withdrawn from the tank. A drop below a predefined limiting value for a fill level of the brake fluid in the tank is monitored with the aid of a binary sensor assigned to the tank. It is provided that an actuation of the pressure generator is monitored and that the available fluid volume is ascertained as a function of the actuation of the pressure generator when the instantaneous fill level drops below the limiting value.

Abstract: A method for operating a vehicle brake system including a brake booster and an electronic traction control device, which is used as a fallback level in a malfunction of the brake booster. The position of an accelerator pedal is ascertained when a malfunction of the brake booster is detected, and under the precondition that the accelerator pedal is released, a predefined initial pressure is built up in a pressure chamber of a master brake cylinder of the vehicle brake system with the aid of the traction control device so that a deceleration of the vehicle is induced. A control unit which is designed to carry out the method, and a vehicle having a vehicle brake system and a control unit, are also described.
