Claims

[Scope of utility model registration request]

In a four-wheeled vehicle 1 having four wheels 11A, 11B, 11C, and 11D, a detection device 2A detects the maximum steering state when a wheel that is steered during a turn is maximally steered to or near the maximum steering angle. ,2B,2C,2D
and the four wheels 11A, 11B, 11C, 1
A selective braking device 3 capable of selectively braking only one of the wheels 1D; and a selective braking device 3 in which the detection devices 2A, 2B, 2C, and 2D detect the maximum steering state of the wheels; The present invention is characterized by comprising a control device 5 that controls the selective braking device 3 so that it can operate to brake the specific wheel only when the vehicle specifies a specific wheel on the inside of the planned direction of the vehicle turn. A small turning device for four-wheeled vehicles.
