PURPOSE:To prevent the fall of driving force at supercharging and always insure good acceleration by detecting supercharged condition of an engine, and regulating the shift-up motion of an automatic transmission at the rise of supercharging pressure. CONSTITUTION:Output of an engine A is transmitted to driving wheels C through an automatic transmission B. On the other hand, a supercharger E is mounted on the intake air passage D of the engine A. Supercharging pressure of the supercharger E is adjusted by a supercharging pressure adjusting means F. Further, speed change of the automatic transmission B is controlled by a speed change control means G. In the above-stated constitution supercharged condition of the engine A is detected by a supercharged condition detecting means H, based on the adjusted condition of the supercharging pressure adjusting means F. The speed change control means G is regulated by a speed change regulating means J, based on the detected signal of the supercharged condition detecting means H. Namely, the shift-up motion of the automatic transmission B is regulated at the rise of supercharging pressure. Thus, the fall of driving force at supercharging is prevented. |
