A turning controller in a vehicle controls turning of each wheel using independent turning actuators for three or more wheels that are not mechanically connected. The vehicle also features a steering command device for automated driving or a steer-by-wire system, which is separated from the turning actuators. The turning controller includes a generator that creates a final steering command value based on signals from the steering mechanism or the steering command device. A calculator within the turning controller then determines a turning angle command value for each wheel, considering the vehicle's speed; higher speeds result in reduced turning angles. Controllers for each turning actuator regulate the driving current to ensure the turning angle matches the command value.
