摘要： A vehicle steering controller includes a turning unit which is mechanically separated from a steering unit, which receives the steering input, and turns the road wheels corresponding to the steering input. The controller also includes a reaction force motor that applies a steering reaction force corresponding to the turning state of the turning unit to the steering unit, a hands-off detection sensor that detects whether the steering unit is in the hands-off state, and a steering reaction force correction component that reduces the steering reaction force from that in the hands-on state when the hands-off state is detected.

A drive torque detector is provided to detect a drive torque imparted to the steering reaction force actuator. A torque sensor is provided to detect an operating torque imparted to the steering wheel. A clutch connection determiner determines that the clutch is in a connected state when a drive torque direction detected by the drive torque detector and an operating torque direction detected by the operating torque detector are different.

The steering rack shaft is split into left and right movable rack shaft portions. Also provided is a steer angle converter enabling a differential rack stroke between left and right rack strokes of the left and right movable rack shaft portions. The steer angle converter is constructed by at least one of a variable-pitch dual rack arrangement and a dual taper-pulley arrangement of a cable back-up mechanism.

摘要： A vehicle control system has a controller comprising a first section for producing a control signal to control the rear wheel steer angle so that the rear wheel steer angle remains equal to a linear combination of a proportional term obtained by multiplying the front wheel steer angle by a proportional coefficient, and a negative derivative term obtained by multiplying the time rate of change of the front wheel steer angle by a derivative coefficient, and a second section which increases the rear wheel steering amount in the direction opposite to the front wheel steering direction by increasing the absolute value of the derivative coefficient with increase in the lateral acceleration of the vehicle or the front wheel steer angle, in order to improve the yawing characteristic of the vehicle in the high lateral acceleration range.
