Abstract
A vehicle control system includes a steering wheel, such as an steering wheel, an adjusting device, a sensor and a control unit. The steering wheel may be actuated by the hand of an operator to set a state variable of the vehicle. The adjusting device applies a force to the steering wheel. A sensor senses a variable representing a state variable of the vehicle and transmits a sensor signal to the control unit. The control unit determines a state variable of the current operating state of the vehicle. The control unit, depending on the current operating state of the vehicle, controls the adjusting device so that a predetermined force is applied to the steering wheel, in order to make the operator aware of an unsafe operating condition.
Claims28
A control system for a vehicle, comprising:
- a steering wheel actuated by an operator to control a travel direction of the vehicle;
- an adjusting device for applying a force to the steering wheel;
- a sensor for sensing a vehicle parameter and transmitting a parameter signal;
- and
- a control unit for receiving the parameter signal, the control unit, depending the parameter signal, controlling the adjusting device to apply a predetermined force to the steering wheel to make the operator aware of a condition of vehicle, wherein a steering resistance is applied to the steering wheel by the adjusting device so that the steering resistance is increased with the amount of a difference between a current position of the steering wheel and a calculated position of the steering wheel, the latter representing a safe and/or optimal operating condition of the vehicle.
