Abstract
A motorized truck with tiller such as a pallet carrier or forklift truck has a tiller-controlled steerable wheelwhich is steered by a motor having an associated steering motor controller. The steering motor controller in a normal mode of operation detects movement of the tiller as it is rotated relative to the chassis to steer the truck, and outputs control signals to cause the steering motor to steer the wheel such that it follows the tiller angle with a fixed, predetermined offset (which may be zero or non-zero). In a realignment mode of operation, the controller can change the predetermined angular offset, and the controller can preferably align the wheel with the tiller or with an axis of the chassis. The truck can be maneuvred more easily into and out of tight spaces with the operator and tiller offset to the side of the truck. The tiller can also be offset manually from the wheel by decoupling the tiller and wheel, and thereby changing the predetermined offset for subsequent operation.
