Power control unit
First Claim
1. A power control unit in a hybrid vehicle comprising:
- an engine and a drive motor which generate a driving force for running;
a vehicle speed sensor which detects a vehicle speed;
an accelerator sensor which detects an amount of accelerator operation; and
a control part having a reference value setting part which determines an output command reference value for said drive motor based on said vehicle speed supplied from said vehicle speed sensor and said amount of accelerator operation supplied from said accelerator sensor, characterized in that;
said control part outputs, to said drive motor, a corrected output command value obtained by adding an additional value corresponding to a rate of change in said amount of accelerator operation to said output command reference value obtained from said reference value setting part.

Abstract
A hybrid vehicle includes an engine and a drive motor which adds power to power generated by the engine in a superimposed manner to assist the engine. A power control unit includes: a fourth rotor sensor as a vehicle speed sensor which detects vehicle speed of the hybrid vehicle; an accelerator sensor which detects an amount of accelerator operation; and an ECU having an assist map which determines an output command reference value for the drive motor based on the vehicle speed and the amount of accelerator operation. The ECU outputs, to the drive motor, a corrected output command value which is calculated by adding an additional value corresponding to a rate of change in the amount of accelerator operation, to the output command reference value obtained from the assist map.
