Abstract
The present invention relates to control system for a vehicle. The control system includes a manually operable control lever, such as a joystick, an actuator, a sensor and a control unit. The control lever sets a state variable of the vehicle. The actuator applies a force to the control lever. The sensor senses a vehicle parameter and transmits a parameter signal to the control unit. The control unit determines a current operating state of the vehicle. The control unit, depending on the present operating state of the vehicle, controls the actuator and causes it to apply a changed, predetermined force to the control lever, in order to make the operator aware of an unsafe operating state.
