IMPLEMENT/VEHICLE STEERING CONTROL SYSTEM AND METHOD
First Claim
1. A control system for steering an implement which is coupled to a utility vehicle, comprising:
- a control unit;
a sensor;
a vehicle hydraulic system;
an electronically actuatable hydraulic valve;
a hydraulic actuator on the implement; and
a steerable wheel on the implement, wherein the sensor detects a status variable of the utility vehicle or of the implement and transmits a status signal to the control unit, the control unit determining an operating state of the utility vehicle and/or of the implement, wherein the hydraulic valve is connected hydraulically to the hydraulic system and the actuator, and wherein the hydraulic valve can be actuated as a function of the operating state of the utility vehicle and/or of the implement in order to block steering of the wheel with the actuator.

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.

16. In a control system for steering an implement which is coupled to a utility vehicle, the implement having a steerable wheel, the control system having a control unit, a sensor, a vehicle hydraulic system, an electronically actuatable hydraulic valve, a hydraulic actuator on the implement, the hydraulic valve being operatively connected to the hydraulic system and to the actuator, a method of operating comprising:
-
detecting with the sensor a status variable of the utility vehicle or of the implement; transmitted the status variable to the control unit; determining with the control unit a current operating state of the utility vehicle and/or of the implement; actuating the hydraulic valve as a function of the current operating state in order to block the steering of the steerable wheel with the actuator.
