<P>PROBLEM TO BE SOLVED: To provide a driving control device of a hybrid car for improving the reducing effects of energy costs when a vehicle travels. <P>SOLUTION: The driving control device of the hybrid car includes: an engine 2 and a motor generator 4 as drive sources; and a battery 13 for supplying power to the motor generator 4, and for charging the power from an external power supply outside the vehicle, and configured to travel while switching to engine traveling or motor traveling. The driving control device includes: a fuel cost calculation part 39 for calculating fuel cost during engine traveling based on the request driving force of a driver; a power cost calculation part 40 for calculating power costs during motor traveling based on the request driving force of the driver; and a drive source selection part 42 and an integral controller 20, for controlling traveling while comparing the calculated fuel costs with the calculated power costs, and selecting a drive source whose cost is more inexpensive. <P>COPYRIGHT: (C)2010,JPO&INPIT |
