ABSTRACT:
A drive system composed of an engine and a transmission is controlled in accordance with a desired wheel toque corresponding to a position of an accelerator, and a present vehicle speed in such a way that a speed ratio of the transmission is determined in consideration with torque factors such as an air-fuel ratio on the engine side, thereby it possible to optimize the control in order to reduce the emission of exhaust substance such as NOx and to enhance the acceleration performance and the fuel economy.
