Method for determining a steering rock force for a steering device in a vehicle, steering device and open-loop and/or closed-loop control device for a steering device
Abstract:
A method for determining a steering rack force (FR) for a steering system of a vehicle, in which a first steering rack force (RFD) is ascertained as a function of at least one force that occurs in the steering system or at least one torque (tor_RA) that occurs in the steering system. So as to provide less strong feedback on the force conditions in the steering system for reasons of driving comfort, in particular when this is currently not required, it is proposed to ascertain a second steering rack force (RFC) as a function of at least one vehicle variable (v, ang_RA), which characterizes the state of movement of the vehicle, and to generate a resulting steering rack force (FR) based on the first steering rack force (RFD) and the second steering rack force (RFC).
