A control system for improving the fuel economy of a hybrid vehicle by evaluating a fuel to be consumed for a charging operation thereby to select a running mode. Specifically, a drive control system for a hybrid vehicle including an internal combustion engine, an electric motor and a battery device. The drive control system comprises: a first evaluator for evaluating the fuel consumption in the case assuming that the run with a demanded power is made by using the electric power reserved in the battery device, while including the fuel consumption at the time when the battery device is charged with the electric power; a second evaluator for evaluating the fuel consumption in the case assuming that the run with the demanded power is made by the motive power generated by burning the fuel in the internal combustion engine; and a motive power selector for selecting one of the run using the electric motor and the run using the internal combustion engine, on the basis of the evaluation results of the first evaluator and the second evaluator.
