PURPOSE:To prevent a change gear shock by restraining the variation of the input number of revolution of an auxiliary change gear device when the difference between an input number of revolution just before L - H switching and a target value is smaller than a set value, and the time differential value of the input number of revolution just before the switching is smaller than a set value. CONSTITUTION:In an electronic control unit 120, the target input number of revolution of a non-stage change gear device 30, that is the target primary number of revolution of the device 30 is set from a throttle opening and a speed detected with sensors 161 and 167. And an input number of revolution just before the L - H switching of an auxiliary change gear device 40 is detected with a primary pulley number of revolution sensor 165, and when the difference between the input number of revolution and the target input number of revolution is smaller than a set value and the time difference value of the input number of revolution is smaller than a set value, the variation of the input number of revolution of the device 40 is restrained. By the way, when the target input number of revolution is varied by the variation of throttle opening, the restraint is released. Thus the occurrence of a change gear shock can be prevented. |
