Abstract
A load drive control system for a hybrid vehicle includes a zero current control execution device and an error compensating device. The zero current control execution device is configured to control a converter to output a substantially constant raised voltage that is higher than an inductive voltage generated in an electric motor. The error compensating device is configured to compensate for an attachment error of a first position detector based on a d-axis voltage command value for the electric motor calculated during zero current control.
