TURNING CONTROL DEVICE

A turning control device is provided for use in a vehicle control system including a steer-by-wire system and a brake system. The turning control device is configured to calculate a braking force difference, which is a difference in braking force between the left and right tire wheels. The turning control device is further configured to perform a high turning control that provides the braking force difference to the left and right tire wheels to cause a smaller turning radius of the vehicle when a steering angle corresponding value is larger than a judgment threshold.
