Abstract: A travel control device for a vehicle has a steered angle varying device 14 or a by-wire type steering device 96 which modifies a relationship of steered angle of steerable wheels to steering operation amount by a driver. When the control device decides that vehicle trajectory control is to be initiated or renewed, it calculates a target steered angle of the steerable wheels for driving the vehicle along a target trajectory which is required for the vehicle to arrive at a target arrival position in a target traveling direction on the basis of steering operation amount by a driver and vehicle speed at a time point of the decision. The control device controls the steered angle of the steerable wheels according to the target steered angle in feed-forward or feed-back manner.

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.
