Steering apparatus for vehicles, has engine for generating steering support force in steering support mode, and reaction force torque by another engine in support compliance mode of traffic line

摘要

The steering apparatus has an engine (6) for generating a steering support force in steering support mode, and a reaction force torque by another engine in a support compliance mode of a traffic line. A detection device (15) is provided for detecting the width of the traffic lane of the road and the position of a vehicle (100) in the width. A control device is provided as electronic control unit (12) to support the compliance of the lane. An ascent slope of the characteristics is changed so that required torque value is preserved as a peak value of absolute value of the reaction force torque.
