To provide a device for reforming a torque as fast as possible after an ASR(Anti-slip control) mode intervening.

This torque reforming device is composed of first means 301, KFFUPSRL for forming a target intake pipe pressure value pssol from a target charge value rlsol so as to deliver a pressure ratio vpsspls of the target intake pipe pressure value with respect to a target supercharge pressure plsol through characteristic maps KFVPDKSD, KFVPDKSE, and second means 304..., 309 for changing the pressure ratio into a value which is smaller than a pressure ratio during steady-state operation, delivered from the characteristic map KFVPDKSD during dynamic running mode so as to gradually shift the pressure ratio from this value into a relatively high value. These means delivers the pressure ratio same as that obtained in the case of the dynamic running mode during the ASR intervening operation.
