Abstract: It is an object of the present invention to provide a controller for a steering apparatus having easy operation of an adjustment of a tilting angle. The steering apparatus comprises a tilting mechanism adjusting a tilting angle of a steering wheel, and an electrical motor driving the tilting mechanism. The controller for the steering apparatus 1 detects the tilting angle based on a rotational angle of the screw shaft. The controller defines the predetermined supplying current according to the detected amount of the tilting angle as the supplying current to the electrical motor.

Abstract: The present invention provides a steering control apparatus that controls steering of a vehicle of a steer-by-wire type, and includes steered-wheel motors that apply separate torques to right and left steered wheels respectively, a rod member that couples the right and left steered wheels so that the steered wheels can be steered, and a steering controller that controls driving of the steered-wheel motors. In each steered wheel, a center of the contact face thereof and a kingpin point thereof are offset in a lateral direction of the vehicle, and the steering controller controls driving of the steered-wheel motors so as to generate a torque difference between the right and left steered wheels, and provides a steering effort in accordance with this torque difference for each of the right and left steered wheels via the rod member, thereby to steer the vehicle.

Abstract: The steered vehicle, which may be a road vehicle or a vehicle devised to be usable upon road surfaces and also upon a rail line, has road wheels or a combination of road and rail wheels as required. The wheels are mounted upon a bogie pivoted about a generally vertical pivot and the vehicle has a main steering control to align at least some of the wheels with the intended direction of travel of the bogie, and a supplementary steering control to modify the steered path produced by that main steering control.
