PURPOSE:To reduce an overload (excessive torque) to the driving system of an automobile, to change speed at an optimal torque, and to reduce the shift shock and the sinking of a vehicle by controlling the timing for ignition, the amount of fuel, and the clutch working oil pressure. CONSTITUTION:In an automobile provided with an engine 1, a change gear 2, and a torque converter 3, the ignition/fuel control A that will be an engine output control means, and clutch working oil pressure control B as change gear control, are carried out. A torque calculation part C for calculating torque based on the signal of an acceleration sensor 4 provided on the automobile, and a slip detection D for determining the speed change rate for the speed change, are also provided. Further, a throttle control system E provided on a suction tube, a throttle valve control F for operating the throttle control system, and a throttle sensor 5 for detecting the throttle opening, are provided. Control signal is output to each control means A, B of fuel ignition system as well as of the change gear, in a controller G, so as to carry out optimal speed change based on each input signal. |
