Abstract
In a controller unit for a hybrid vehicle, a generation controller controls the quantity of electric power generated by a motor generator, and a fuel cut controller stops fuel supply to the engine if a predetermined fuel cut condition is satisfied. The generation controller controls so that the quantity of electric power generated is set at predetermined values according to the engine speed, and is set at different values, at the same engine speed, according to whether the fuel cut occurs or not. Thus, the quantity of power generation does not decrease more than needed to prevent engine stall. When the fuel cut is not performed, the generation controller in particular increases the quantity of power generation, which charges the battery more and reduces fuel consumption.
