ABSTRACT:
A control system for supercharging an internal combustion engine equipped with an automatic transmission includes a capacity changeable supercharger. The supercharger is controlled by a supercharging capacity controller, having data representative of at least one supercharging capacity control line, so that its supercharging capacity is charged according to operating conditions of the internal combustion engine. A transmission shift controller, causing the automatic transmission to shift according to operating conditions of the internal combustion engine, has data representative of at least one gear shift control line for a shift operation of the automatic transmission. The at least one gear shift control line has an intermediate portion, including an intersection with the supercharging capacity control line defined by a specific engine load between upper and lower middle vehicle speeds. The shift controller causes a shift of the automatic transmission prior to changing the supercharging capacity at engine operating conditions near an engine operating condition at the intersection.
