  • Patent number: 7729830
    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.

  • Publication number: 20090032273
    Abstract: A control system controls steering of an implement which is coupled to an agricultural utility vehicle. The control system includes a control unit, a sensor, a hydraulic system on the utility vehicle, an electronically actuatable hydraulic valve, a hydraulic actuator on the implement and a steerable wheel on the implement. A status variable of the utility vehicle or of the implement can be detected with the sensor and transmitted to the control unit. A current operating state of the utility vehicle and/or of the implement is determined by the control unit. The hydraulic valve is connected to the hydraulic system and to the actuator. The hydraulic valve can be actuated as a function of the current operating state of the utility vehicle and/or of the implement in order to block the steering of the wheel with the actuator.

  • Publication number: 20080275606
    Abstract: The invention relates to a vehicle active suspension system. There is a need for an active suspension system which can alert an operator to certain conditions. The suspension system includes an actuator for moving a second vehicle part relative to a first vehicle part. The suspension system also includes sensors and a control unit. A vehicle operator is located in or on the second part. The sensors sense vehicle parameters and transmit parameter signals to the control unit. In response to the parameter sensors, the control unit causes the actuator to move the second part in such a manner that the movement alerts the operator to the existence of a condition, such as a critical or non-optimal operating state of the utility vehicle or of an implement coupled to the vehicle.

  • Publication number: 20080275596
    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.
