Abstract
In a state a vehicle is stopped at an intersection, an infinitely variable transmission is in a neutral position, a motor/generator rotates with a low speed, an oil pump and an auxiliary equipment are in rotating state. At that time, an input clutch is disengaged, and the internal engine is stopped. When the vehicle is started, a continuously variable transmission performs continuous shift control from the neutral position using hydraulic pressure from an oil pump, and the rotation of the motor/generator is transmitted to drive wheels via a ring gear of a planetary gear. After the vehicle has started driving, the input clutch is engaged and the internal engine is started. The vehicle is driven while the motor/generator assists driving or the motor/generator charges batteries based on operation of the internal engine.
