PROBLEM TO BE SOLVED: To suppress the lowering of drivability during torque-down control, and to suppress a delay of a response of actual torque with respect to a torque requirement of a driver at a return from the torque-down control.SOLUTION: According to an electronic control device 100, in the case that there are performed PCS torque-down control for lowering supercharging pressure Pcmout in a state that the requirement torque Tedri of a driver is maintained, and VSC torque-down control having a torque-down requirement &Dgr;Tevsc equal to or larger than a torque-down requirement &Dgr;Tepcs of the PCS torque-down control, and permitting a rise of the supercharging pressure Pcmout, the supercharging pressure Pcmout is raised at a preset change amount. In the case that the requirement torque Tedri of the driver is raised when the requirement torque Tevsc by the VSC torque-down control is maintained, a change amount of the supercharging pressure Pcmout is set large according a change amount of the requirement torque Tedri of the driver.SELECTED DRAWING: Figure 4 |
