PURPOSE:To carry out control of vehicle condition at an optimum timing by carrying out control of vehicle condition based on the actual speed change action when the actual speed change action is judged based on the width change from a changed curve point of an output axial rotational speed after the speed change of the auxiliary transmission is judged. CONSTITUTION:In a transmission controller consisting of a belt continuously variable transmission(CVT), the transmission gear ratio of which is varied continuously by a hydraulic cylinder, and of an auxiliary transmission to be connected to a rear step of the CVT, which can be switched into a plurality of forward gear steps, a speed change judgement means for judging the speed change of the auxiliary transmission and an output shaft rotational number detection means for detecting the output shaft rotational number of the CVT are provided. The speed change judgement means for detecting the actual speed change action of the auxiliary transmission based on the width change from a changed curve point of the detected output shaft rotational number, is provided. When the actual speed change action is judged by the speed change action judgement means after the speed change of the auxiliary transmission is judged by the speed change judgement means, the vehicle condition is controlled based on the actual speed change action by a vehicle condition control means. |
