Patent ID: 8485940

Claim:
A power control device comprising: an engine provided as a power source for running a vehicle, equipped with a supercharger, and capable of supercharging using the supercharger; and a power control unit provided so as to control power of the engine and configured such that if an actual operating point, which is an operating point indicating a combination of actual revolution speed and torque of the engine, is located in a non-supercharging region, which is a region where supercharging cannot be carried out with the supercharger in an operation region of the engine, and if a target operating point, which is an operating point serving as a target during the acceleration, is located in a supercharging region, which is a region where supercharging can be carried out with the supercharger in the operation region of the engine, the revolution speed of the engine is increased while the torque of the engine is increased to a maximum in the non-supercharging region on a power contour line, which indicates the revolution speed and torque of the engine that actualize power equal to power at the target operating point, until the actual operating point is shifted into the supercharging region, thereby the actual operating point is shifted to a point at which the power contour line and the boundary between the non-charging region and charging region intersect, and the revolution speed of the engine is decreased after the actual operating point has entered the supercharging region, the revolution speed of the engine is decreased, thereby shifting the actual operating point into the target operating point when accelerating the vehicle.
