ABSTRACT:
A method of controlling a power transmitting system for an automotive vehicle, having a continuously variable transmission and an auxiliary transmission which is connected with the continuously variable transmission, and which has at least two shift positions for forward driving of the vehicle. The auxiliary transmission is automatically shifted from one of the shift positions to another, based on a detected speed, a detected currently required output of the vehicle, and a detected speed ratio of the continuously variable transmission. Alternatively, the auxiliary transmission is shifted from one of the shift positions to another in response to an operation of a manual shift lever. When a predetermined condition is satisfied after the shift lever is operated to a given position, the auxiliary transmission is permitted to be shifted to the shift position corresponding to the position of the shift lever. This condition is determined based on the detected speed, the currently required output of the vehicle, and the detected speed ratio of the continuously variable transmission. Also disclosed are devices suitable for practicing the methods.
