  • Patent number: 12654560
    Abstract: A brake device for a vehicle. The brake device includes a controller, which is connected to a brake actuator device. The controller is configured to ascertain an operating state of an electric machine in generator mode and a second brake torque, which can be generated by the electric machine, and to operate the brake actuator device in generator mode as a function of the operating state. A specified total brake torque on the vehicle can be generated as the sum of the second brake torque and a first brake torque of the brake actuator device. The controller is configured to reduce or increase the generated first brake torque of the brake actuator device to maintain a specified value range of an operating parameter of the brake actuator device and/or to provide, together with the second brake torque, at least the specified total brake torque on the vehicle.

  • Publication number: 20250353477
    Abstract: A method for operating a braking system in a vehicle. First calibration data are transmitted from a first sensor arranged on a brake pedal of the vehicle to a first braking product and/or second calibration data are transmitted from a second sensor arranged on the brake pedal of the vehicle to a second braking product. First and second sensor data are generated by the first and second sensors according to an actuation of the brake pedal by a user. The first and second sensor data are transmitted to the first and/or second braking product. Based on ascertaining that the first and the second braking products are present in the vehicle, the braking system is operated in a first operating state. Based on ascertaining that only the first braking product or only the second braking product is present, the braking system is operated in a second operating state.

  • Publication number: 20250074378
    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.

  • Patent number: 12172621
    Abstract: A method for operating a brake system of a vehicle, in particular, of a motor vehicle. The brake system includes at least one electric actuator, in particular, a brake booster, which may be driven to generate a braking force, the actuator being controllable by an autonomous driving system, and as a function of manipulation of a brake pedal of the vehicle; and an emergency braking action being initiated, when the actuator is driven both by the autonomous driving system and by manipulation of a brake pedal. The control by the autonomous driving system is superimposed with a varying validation signal, a differential travel between an actuator element of the actuator and the brake pedal is monitored, and the driving of the actuator via manipulation of the brake pedal during the control by the autonomous driving system is detected, if the differential travel varies.

  • Patent number: 12122344
    Abstract: 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.

  • Publication number: 20240272020
    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.
