<P>PROBLEM TO BE SOLVED: To provide a drive control device of a hybrid vehicle that can decrease starting frequency of an engine. <P>SOLUTION: In the drive control device 2 of the hybrid vehicle, where the engine 5 and MG2 that is an electric motor are used as the motive power of the vehicle 1 in traveling, and the MG2 has a power generation function, and in addition, the vehicle 1 can be travelled in the state where the engine 5 is stopped, the temperature of the MG2 is forecasted based on the information of the road where the vehicle 1 travels at EV traveling that is the traveling of the vehicle in the state where the engine 5 is stopped, and the power generation by the MG2 is prohibited when the forecasted temperature of the MG2 becomes equal to or more than the prescribed value. Thereby, the temperature rise of the MG2 at EV traveling can be controlled and the frequency that needs the cooling of the MG2 that is performed by starting the engine 5 and making the lubricating oil circulate can be decreased. As a result, the starting frequency of the engine 5 can be decreased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
