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

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.

Steer-by-wire steering system for a vehicle, and method for operating a steer by-wire steering system

A method for operating a transportation vehicle function based on a natural frequency and/or a moment of inertia of a steering wheel arrangement in a steering system including prespecifying an electromotive steering intervention to move the steering system by providing a steering intervention force or a steering intervention torque; ascertaining a natural frequency and/or a moment of inertia of the steering wheel arrangement depending on the response of the steering wheel arrangement based on the electromotive steering intervention; and operating the transportation vehicle function based on the ascertained natural frequency and/or the ascertained moment of inertia of the steering wheel arrangement.
