Abstract
A steering system with at least one steering wheel actuator and at least one steering actuator which are connected to each other via a controlled system. Minimal steering impulses being superimposed in order to be able to determine the steering tie rod forces that occur.
Description
FIELD OF THE INVENTION
[0001] The invention concerns a steering system.
BACKGROUND OF THE INVENTION
[0002] The objective of the invention is achieved by a steering system of the type described.
BRIEF DESCRIPTION OF THE DRAWING
[0003] The invention will now be described, by way of example, with reference to the accompanying drawing in which:
[0004]
FIG. 1 is a steering system.
DETAILED DESCRIPTION OF THE INVENTION
[0005]
FIG. 1 diagrammatically shows a steering system 2 having at least a steering wheel actuator 4 and at least a steering actuator 6 connected together via a controlled system 8. Minimal steering impulses are superimposed in the steering system 2 in order to be able to determine forces that occur on a steering tie rod 10 of the steering system 2. The steering impulses are sinusoidal oscillations superimposed in the steering system 2. The steering actuator 6 comprises an electric motor which can act upon a steering mechanism of a power-assisted steering system. The steering wheel actuator 4 comprises an electric motor which transmits a torque, via a steering wheel 12, back to a driver.
Claims
- 1. Steering system with at least one steering wheel actuator and at least one steering actuator, which are connected together via a controlled system, characterized in that minimal steering impulses are superimposed in the steering system in order to be able to determine the steering tie rod forces that occur.
- 2. Steering system according to claim 1, characterized in that the steering impulses are sinusoidal oscillations
- 3. Steering system according to claim 1, characterized in that the value of the steering tie rod forces can be determined with reference to the flank shape of the steering impulses.
- 4. Steering system according to claim 1, characterized in that the steering actuator comprises an electric motor which can act upon a steering mechanism of a power-assisted steering system.
- 5. Steering system according to claim 1, characterized in that the steering wheel actuator comprises an electric motor which transmits back to the driver a torque via the steering wheel.
