Vehicle control system
First Claim
1. A control system for controlling a self-propelled tractor, comprising:
- a manually operable control lever for generating a control signal;
an actuator for applying a force to the control lever;
at least one sensor; and
a control unit for determining an operating state of the self-propelled tractor, the sensor supplying a parameter signal to the control unit;
wherein the control unit, depending on the operating state of the self-propelled tractor, causing the actuator to apply a predetermined force to the control lever to make the operator aware of an operating condition, and the control unit varying the force applied to the control lever as a function of the parameter signal so that the operator can re-find a setting, a deflection position or a deflection range of the control lever; and
wherein the control unit generates a visual and/or an acoustic signal.

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.
