出力する、差動制御装置。 A device for controlling the differential of a differential device in a vehicle that drives left and right wheels by a differential device having a differential limiting mechanism that can continuously change the differential limiting amount, the device detecting vehicle speed. means for detecting the steering angle, means for detecting the rotation speed of the left drive wheel, means for detecting the rotation speed of the right drive wheel, means for detecting the presence or absence of braking, and from these means The controller includes a controller that receives a signal, and means that is controlled by the controller and operates the differential limiting mechanism, and when the vehicle is traveling straight at a certain speed or higher without braking, the controller controls the left and right drive. The presence or absence of a difference in tire diameter is determined from the difference in the rotation speed of the wheels, and if there is a difference in tire diameter, the above-mentioned Outputs a differential control signal that changes according to the value after subtracting the correction value due to the difference in tire diameter, and outputs a differential control signal that changes according to the vehicle speed and steering angle when there is no difference in tire diameter. , differential control device.
