  • Patent number: 11970222
    Abstract: A method for actuating a vehicle steering actuator which is coupled to a steering gear, comprising: providing an end stop return function with which a first control variable for the vehicle steering actuator can be ascertained, on the basis of which a force that returns the steering gear in the direction of a defined position can be at least partially generated with the vehicle steering actuator; ascertaining whether the steering gear falls below a limit distance from an end stop; and if this is the case: actuating the vehicle steering actuator on the basis of the first control variable ascertained with the end stop return function, which control variable has a value above a threshold value; wherein, if the limit distance is not fallen below, no control variable is ascertained with the end stop return function or a control variable with a value not exceeding the threshold value.

  • Patent number: 11338845
    Abstract: A method for operating an electrical power steering system of a transportation vehicle wherein a steering wheel angle is pre-defined by a steering wheel as a measure for a desired wheel steering angle for at least one steerable wheel of the transportation vehicle, where an electrical power drive with an electric motor provides a steering support, and where a support torque of the steering support is reduced based on a damping function in response to the combustion engine of the transportation vehicle being started. Also disclosed is an associated electrical power steering system, to a computer program, and to a control appliance.

  • Patent number: 10836422
    Abstract: A method for operating an electric power steering system of a motor vehicle, wherein a steering wheel angle is specified by a steering handle as a measurement for a desired wheel steering angle for at least one steerable wheel of the motor vehicle, wherein an electric servo drive having an electric motor provides steering assistance, and wherein an additional restoring force is provided to compensate for increased internal friction in the power steering system based upon temperature, wherein the additional restoring force is reduced based upon a desired steering direction that is detected at the steering handle. Also disclosed is an associated electric power steering system, an associated computer program, and an associated control unit.
