PURPOSE:To make running so as to satisfy the optimum fuel consumption characteristic or the maximum power characteristic by constituting so that, when a request for acceleration is caused, a torque ratio fixing means fixes the ratio to a target torque ratio, and that a speed-change operating means is controlled on the basis of the fixed signal from the target torque ratio setting means. CONSTITUTION:The rotating speed of an engine E is continuously changed by an automatic continuously variable transmission 1 to travel a vehicle. In this case, a target torque ratio is set by a target torque ratio setting means 121 in a control part 120 to satisfy prescribed characteristics such as the maximum power characteristic or the optimum fuel consumption characteristic, and the automatic continuously variable transmission 1 is controlled by a speed-change operating means 100 so as to meet this target torque ratio. On the basis of the signal from acceleration condition sensors, when an acceleration request judging part 200 judges that there is an acceleration request, a torque ratio fixing means 122 fixes the target torque ratio to a prescribed torque ratio within the range of a prescribed engine speed based on an acceleration sense setting means 143. Thus, when an acceleration is requested, the speed-change operating means 100 is controlled by this fixed signal from the setting means 121. |
