速機の制御装置。[Scope of Claim for Utility Model Registration] The vehicle speed at the shift point is determined from the throttle valve opening of the engine based on a shift map stored in advance, and the vehicle speed at the shift point is compared with the actual vehicle speed to determine the shift speed. In a control device for an automatic transmission that includes a transmission control unit that performs determination and that changes gears upon receiving a shift control command signal from the transmission control unit, a rotation speed that detects a rotation speed difference between wheels of a vehicle is provided. An automatic gear shift characterized in that it is provided with a difference detection means and a shift-up prohibition means for prohibiting a shift-up when the rotation speed difference of the wheels detected by the rotation speed difference detection means becomes larger than a preset value. Machine control device.
