動制御装置。 A device for controlling the differential of a differential device in a vehicle that drives left and right wheels on the front side or rear side by a differential device having a differential limiting mechanism, the device comprising: means for detecting vehicle speed; and a steering angle. means for detecting the rotation speed of the left wheel on the front or rear side; means for detecting the rotation speed of the right wheel on the front or rear side; and a controller receiving signals from these means. A controller that calculates a rotational speed difference between the left and right wheels on the front side or rear side, calculates a reference rotational speed difference from the vehicle speed and steering angle, and compares the reference rotational speed difference with the calculated rotational speed difference. and the controller is a means for operating the differential limiting mechanism, and when the calculated rotational speed difference is within a certain range of a reference rotational speed difference, the controller reduces the differential limiting amount of the differential limiting mechanism. and operating means controlled by the differential control device.
