<P>PROBLEM TO BE SOLVED: To provide a vehicle controller that, when CPU is reset, keeps a system main relay (SMR) uninterrupted for a predetermined time to maintain conduction and, when the CPU is started during this period, does not hinder running. <P>SOLUTION: A hybrid automobile 10 includes a power system and a control system. The power system includes: the SMR 32 and the like that connect or disconnect a high-voltage battery 36 and a step-up converter 21; an electric inverter 24 connected to the step-up converter 21; and a vehicle motor 27 connected to the electric inverter 24. The control system includes: an SMR control signal unit 40 that transmits control signals to the SMR 32 and the like; and a control ECU 11 that outputs control signals to the control signal unit 40. A first relay controlling means includes the control ECU 11 and a control signal hold circuit 41, and a second relay controlling means includes the control ECU 11 and a forcible SMR interruption circuit 42. <P>COPYRIGHT: (C)2008,JPO&INPIT |
