PURPOSE:To harmonize both demands for prevention of the occurrence of a switching shock and improvement of acceleration performance with each other according to a demand occasioned by a transmission ratio state, by a method wherein, during the starting of supercharging, the rising state of a supercharger is controlled depending upon an acceleration state and a transmission ratio. CONSTITUTION:When an acceleration state, e.g., a throttle opening speed, detected by an acceleration state detecting means C, exceeds a set value, rapid closing of, for example, a bypass control valve causes control of a supercharging state. A set value is varied with a transmission ratio detected by a transmission ratio detecting means E. During low gear running, a set value is increased to decrease production of an acceleration shock, and during high gear running, a set value is decreased to improve a supercharging response.
