摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method for controlling a power brake system, for a motor vehicle engaged in piloted driving, which includes two electrically controllable actuator units. The first actuator unit includes a braking-intent detection device, and a first pressure generation unit for generating a brake pressure in a brake circuit. The second actuator unit includes a second pressure generation unit redundant to the first pressure generation unit. A first electronic control device acquires signals of the braking-intent detection device and controls the actuator unit based on the detected braking intent. In response to detected functional impairment, the first motor of the pressure generation unit ceases to be controlled, and the second motor of the pressure generation unit of the second actuator unit is controlled to generate brake pressure. Detection of a braking intent and wheel-specific modulation of the brake pressure, continue to be carried out, using devices of the first actuator unit.

摘要： An actuating apparatus for a vehicle, in particular a motor vehicle, includes (i) at least one first actuating surface for specifying a braking request, (ii) at least one second actuating surface for specifying an acceleration request, (iii) a first sensor unit for detecting an actuation of the first actuating surface, in particular an actuating force exerted on the first actuating surface, and (iv) a second sensor unit for detecting an actuation of the second actuating surface, in particular an actuating force exerted on the second actuating surface. At least one of the sensor units is provided for detecting an actuation of both actuating surfaces.

摘要： The method relates to a method for boosting the braking force in an electromotor operated slip-controllable vehicle brake system having electromechanical brake boosting. The vehicle brake system includes a braking-intention detection device, an electromechanically actuatable brake booster, and an electronically actuatable brake-pressure control device. In the event of a malfunction of the brake booster, the boosting of the brake pressure is alternatively assumed by the brake-pressure control device. In the event of a malfunction of the brake boosting, it is checked whether a generation and a transmission of a trigger signal representing the actuation of the braking-intention detection device from the first electronic control device of the brake booster to a second electronic control device of the brake-pressure control device is possible, and if this is so, the trigger signal is transmitted via an existing communications link between the control devices.

摘要： 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.
