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.
