ABSTRACT:
A driving power control device for a hybrid vehicle controls the engagement state of a lockup clutch so that high efficiency in regeneration is obtainable. The driving power control device for a hybrid vehicle includes an engine and a motor-generator as power sources, an automatic transmission disposed between the power sources and driving wheels with an intervening torque converter having a lockup clutch, and an ECU for controlling selection of the power sources and for controlling a slip ratio of the torque converter. In this control device, a target slip ratio of the torque converter, which corresponds to a target amount of regeneration that is retrieved using regeneration amount determining factors, is obtained by executing a feedforward control operation using friction torque determining factors, and the slip ratio is controlled in a feedback manner based on the difference between the target slip ratio and the actual slip ratio.
