摘要： In a vehicle steering device and control method, a selectively engageable clutch is positioned between a steering wheel and a turning mechanism for turning at least one wheel. The clutch has an engaged position where the steering wheel is mechanically connected to the turning mechanism and a disengaged position where the steering wheel is mechanically separated from the turning mechanism for steer-by-wire control. During steer-by-wire control, a reaction force actuator applies a force to the steering wheel, and a turning actuator applies a torque to the turning mechanism. To prevent erroneous clutch engagement caused by an increase in relative angular acceleration between the steering angle and the turning angle, a controller detects an operating condition corresponding to a risk of erroneous clutch engagement and controls at least one of the turning actuator and the reaction force actuator to reduce the relative angular acceleration.

摘要： A steering control device in which a steering portion including an electric steering reaction force actuator and a steered portion including an electric steered portion actuator are mechanically disconnectable and connectable via backup means. A steer-by-wire control means is provided for disconnecting the backup means and performing steer-by-wire control using control of the steered portion actuator to set a steered angle corresponding to the steering condition and using control of the steering reaction force actuator to add a steering reaction force corresponding to the steered condition. A steering assistance control means is also provided for connecting the backup means and performing steering assistance control by adding a steering aid force using at least one of the steering reaction force actuator and the steered portion actuator. The power supply capacity of a steered vehicle is selectively estimated and if the estimated power supply capacity reaches a predetermined value or below during the steer-by-wire control, steering is switched to the steering assistance control.

摘要： A braking force control apparatus for use with an automotive vehicle supported on road wheels each of which has a wheel cylinder for applying a braking force to the corresponding road wheel in response to a fluid pressure introduced thereto. The fluid pressure is controlled by a solenoid valve which is movable between open and closed positions in response to a control signal having a variable duty ratio. The duty ratio of the control signal is changed at predetermined intervals of time to move the solenoid valve in a plurality of steps toward the closed position.
