Abstract
A controller for a vehicle transmission in which a continuously variable transmission mechanism able to continuously change its speed ratio and a transmission mechanism having a constant speed ratio are provided in parallel between an input shaft and an output shaft. The transmission includes a friction engagement mechanism and an intermeshing engagement mechanism, the intermeshing engagement mechanism being arranged in series with the friction engagement mechanism, the intermeshing engagement mechanism setting the transmission mechanism to a state where torque is transmittable between the input and output shaft, in changing to a state where the intermeshing engagement mechanism is engaged and the transmission mechanism is able to transmit torque to the output shaft, a torque capacity of the friction engagement mechanism is configured to be increased to a torque capacity to such extent that the transmission mechanism rotates without a delay of start of engagement of the intermeshing engagement mechanism.
