Abstract
An off-highway vehicle having an earth moving implement has a tilt function associated with the implement. For example, a bulldozer has a tilt function associated with the bulldozer blade. The vehicle has a processor adapted to receive a position signal from a position sensor associated with the tilt function of the implement. The operator engages a switch to activate an automatic tilt function. A selector switch is provided so that the operator can select between a plurality of pre-set blade angles. The selector switch outputs a target position signal associated with a pre-set angle to the processor. The processor automatically calculates a command signal for the tilt function based on the difference between the position signal and the target position signal. The processor issues the command signal to the tilt function causing the tilt function to move the implement to the pre-set angle associated with the switch position.
