PURPOSE:To carry out speed change conformable to the intension of a driver by making fuzzy reasoning based on signals indicating vehicle speed, acceleration, engine load, variation rates thereof and running resistance, then determining a gear position. CONSTITUTION:Operating condition signals of a vehicle detected through means for detecting vehicle speed, engine load, variation rate of engine load and running resistance are provided to a speed change ratio determining means. The speed change ratio determining means makes fuzzy reasoning based on a membership function of a fuzzy set preset by a membership function setting means and determines a specific speed change ratio. A speed change actuator is driven through a drive means based on the determined speed change ratio so as to carry out specific speed change. Consequently, the vehicle can be operated through fuzzy control with such speed change ratio as can be obtained through human judged operation. |
