Abstract:
1. A drive control device controlling a drive device for a vehicle, the drive device being provided with a plurality of rotating electrical machines and a drive unit driving said plurality of rotating electrical machines, said drive unit including a direct-current power supply, and a power conversion unit which converts direct-current power obtained from said direct-current power supply into alternating-current power, and supplies said alternating-current power to said plurality of rotating electrical machines, said drive control device comprising: an electrical leak detection unit detecting electrical leak in said drive device; and an operation determination unit identifying an electrical leak location based on a result of the detection made by said electrical leak detection unit, and determining which rotating electrical machine out of said plurality of rotating electrical machines is allowed to operate when said vehicle is driven next time, in accordance with said electrical leak location being identified, while said vehicle is stopped, wherein when said operation determination unit identifies at least one of said plurality of rotating electrical machines as said electrical leak location, said operation determination unit allows an operation of said plurality of rotating electrical machines other than said at least one rotating electrical machine and inhibits an operation of said at least one rotating electrical machine, and when said operation determination unit identifies said power conversion unit as said electrical leak location, said operation determination unit inhibits the operation of each of said plurality of rotating electrical machines.
