A steering assistance method based on a driver assistance system, for a transportation vehicle with a steering system with steering assistance for assisting a driver during the steering of the transportation vehicle by the steering system, in which a driving situation of the transportation vehicle is detected; acting upon the driving behavior of the transportation vehicle according to the driving situation, the supporting driver assistance system defining a nominal value for at least one regulating variable of the steering system and conditionally requesting same from the steering system by a driver assistance interface; and generating a corrective action by a monitoring function downstream of the driver assistance interface and upstream of the request to the steering system, in response to the nominal value not meeting a pre-defined permissible criterion. A steering assistance based on a driver assistance system and a transportation vehicle.

Steering assistance method based on a driver assistance method, steering assistance system and transportation vehicle

A steering drive system for a steering system of a transportation vehicle having a first control unit for actuating a first winding circuit of a steering drive motor with a test circuit to make available a defined changing test signal and a second control unit for actuating a second winding circuit of the steering drive motor, wherein a test signal reception circuit of the second control unit receives the test signal, and wherein the second control unit actuates the steering drive motor based on the presence or absence of the test signal.

Electromechanical steering drive system for making available steering assistance for a steering system

An apparatus is provided for measuring a torque in a force-feedback actuator for a steer-by-wire steering system has a housing element, a control unit, a drive apparatus, and a transmission apparatus to be coupled to a steering device. At least one motion sensor detects a motion of the transmission apparatus relative to the housing element and provide a motion signal resulting from the motion to the control unit. The transmission apparatus is coupled to the housing element by way of at least one reset-reversible adjusting device which has at least one mechanical property. A torque of the transmission apparatus, and thus of a connectable steering device, may be ascertained by the control unit using the at least one mechanical property, which has at least one changing state value during the movement of the transmission apparatus, in combination with the motion signal.

An operating method for a steer-by-wire steering system having a steering gear module, a steering wheel module, and a bus connecting the steering gear module and the steering wheel module, wherein an actual position in the steering gear module is sensed and a setpoint position in the steering wheel module is adjusted in relation to the actual position in the steering gear module by using an association specification. Also disclosed is a control unit for a steer-by-wire steering system, a steer-by-wire steering system, and a transportation vehicle having a steer-by-wire steering system.

Operating method for a steer-by-wire steering system, control unit for a steer-by-wire steering system, steer-by-wire steering system, and transportation vehicle

A steer-by-wire steering system for a vehicle is disclosed, comprising a steering wheel unit, connected with a wheel unit. The steering wheel unit has a steering wheel angle sensor, a steering wheel actuator for setting a steering wheel target torque, and a steering wheel controller for actuating the steering wheel actuator. The wheel unit has a steering sensor for capturing at least one actual steering value, a wheel actuator for setting a target steering value, and a wheel controller. The wheel controller is designed to calculate a virtual torsion rod torque based on the target steering value and the actual steering value, to actuate the wheel actuator based on the calculated virtual torsion rod torque, and to transfer the calculated virtual torsion rod torque to the steering wheel unit. The steering wheel controller is designed to calculate the steering wheel target torque based on the transferred virtual torsion rod torque.
