Abstract
A method for operating a steering system and such a steering system are presented. The steering system includes a steering wheel which acts on a steering rack via a steering pinion of a steering column, wherein a steering torque is transmitted to the steering rack by means of the steering wheel. Furthermore, a steering assistance unit is provided, by means of which a steering assistance torque can be applied to the steering rack. A control circuit with which the steering assistance torque is regulated, is used, wherein the control circuit takes into account the mass inertia of the steering column.
Claims7
A method for operating a steering system including a steering wheel which acts on a steering rack via a steering pinion of a steering column, said method comprising the steps of:
- (i) transmitting a steering torque to the steering rack by means of the steering wheel, (ii) calculating, by means of a control circuit, a steering assistance torque as a function of a mass inertia of the steering column, and (iii) applying the steering assistance torque to the steering rack by means of a steering assistance unit.
A steering system comprising:
- a steering wheel which acts on a steering rack via a steering pinion of a steering column, wherein a steering torque is transmitted to the steering rack via the steering wheel,
- a control circuit that is configured to calculate a steering assistance torque as a function of a mass inertia of the steering column, and
- a steering assistance unit by means of which the steering assistance torque is applied to the steering rack.
