Abstract
A vehicle steering system has a steering grip, in particular a steering wheel, which is operated by the driver, an actuating unit which operates steered vehicle wheels, and a manual force regulator which is coupled via a flexible coupling element with the steering grip and simulates parameter-dependent steering forces on the steering grip. A damping device is provided for reducing the formation of vibrations between the steering grip and the manual force regulator. The damping device interacts with the steering grip either directly or indirectly to damp relative motions between the steering grip and the manual force regulator.
Claims10
A steering system for a vehicle, the steering system comprising
- a steering grip operatable by a driver;
- an actuating unit for operating steered vehicle wheels of the vehicle;
- a steering angle setpoint generator for responding to the steering grip and producing a steering angle setpoint signal;
- a steering angle actual-value sensor for responding to the steered vehicle wheels and producing an actual steering angle value signal;
- a controller arrangement for activating the actuating unit as a function of a comparison between the steering-angle setpoint signal and the actual steering angle value signal;
- a manual force regulator coupled via a flexible coupling element with the steering grip, the manual force regulator for simulating steering forces on the steering grip;
- and
- a damping device for interacting with the steering grip directly or indirectly to dampen relative adjusting motions between the steering grip and the manual force regulator.
