Supercharger control apparatus for the internal combustion engine of a motor vehicle comprises a control device which has as input signals the demand signal for acceleration (such as a signal based on the amount of throttle valve opening) and an engine rotational speed signal. Based on predetermined ranges of demand signal for acceleration and engine rotational speed and on the input signals, the control device regulates, through an actuator and bypass valve or through an actuator and variable capacity compressor, the amount of supercharging. The supercharge control apparatus allows a non-supercharged state, a maximum supercharged state, or an intermediate supercharged state. In the intermediate supercharged state, the amount of supercharging is in incremental steps to prevent hunting.
