  • Patent number: 11919586
    Abstract: The application relates to a method for operating an actuator for a motor vehicle, the actuator having an actuating drive and a signal input. The actuating drive is operated as a function of a setpoint value received via the signal input and a threshold value stored in the actuator for setting an actual value of the actuator to the setpoint value, wherein the threshold value is set equal to the setpoint value when the actuator leaves an operating range of the actuator defined by the threshold value of the setpoint value. The application further relates to an actuator for a motor vehicle and a method for operating an arrangement of an actuator and a control unit for a motor vehicle.

  • Publication number: 20230174147
    Abstract: A method for controlling an active rear axle steering of a motor vehicle when steering out from straight travel with given actual dynamics of the wheel guidance of the motor vehicle, wherein an actual steering signal of the motor vehicle is received by a control circuit from at least one sensor, then from the actual steering signal a dynamic model of the wheel guidance calculates a time variation of a differential signal describing a deviation of the actual steering signal from an imaginary nominal steering signal which would be needed in order to perform the steering with a given nominal dynamics, and from the differential signal a predetermined conversion rule is used to generate a nominal steering signal for the rear axle steering and the rear axle steering is actuated with this.

  • Patent number: 11370484
    Abstract: A method for steering a vehicle that comprises a steering system with a steering wheel and a front axle as well as a rear axle with wheels, wherein it is provided that a direction of the vehicle is adjusted manually by a driver of the vehicle by adjustment of a steering wheel angle of the steering wheel, as a result of which, for the wheels of at least one of the axles, a steering angle is adjusted, which is obtained from the steering wheel angle plus a superposition angle, wherein, through an automatically adjustable steering ratio for the wheels of at least one of the axles, a ratio of the steering wheel angle to the steering angle for the wheels is set, wherein the vehicle travels into a curve on a circular path with a radius at a speed with a first value, wherein a steering wheel angle is adjusted by the driver.

  • Patent number: 11059515
    Abstract: A method for control of a rear-axle steering of a motor vehicle. A steering angle of wheels of a rear axle is set. Upon reaching a predetermined lateral acceleration of the motor vehicle, the steering angle and/or the gradient of the steering angle of the wheels of the rear axle is limited as a function of a coefficient of friction of a roadway surface on which the motor vehicle is moving.
