<p>PURPOSE:To improve fuel economy and accelerating property simultaneously by providing a calculating means for controlling the rate of a wheel seed/engine speed and air-fuel ratio simultaneously relating to each other from demanded wheel torque and vehicle speed. CONSTITUTION:A speed ratio control device 16 iis provided to control the speed ratio of a transmission 15 for transferring power of an engine 1 to an intake compressor 7, and also a valve opening/closing timing control device 17 is provided. A clutch control means 21 is provided to control a clutch 2 for transferring power of the engine to the input shaft of a transmission 3 for running, and also a speed apparatus restricting means 22 is provided control to the speed ratio of the transmission 3. Those control devices 17, 16, 21, 22 are controlled while relating to each other by control units 20, 23. Namely, for example, when the demand torque of an engine is small, the closing angle of an intake valve 9 is delayed, and compressing work is reduced so as to improve fuel economy, and also the rotating speed of the compressor 7 is reduced by a speed ratio control device 16 so as to reduce boost pressure down to near the atmosphere pressure.</p> |
