摘要： PROBLEM TO BE SOLVED: To run a vehicle even when any failure occurs in a generator. SOLUTION: When a generator 8 fails, an electric motor 3 regenerates power, and an auxiliary battery 11 is charged without any deceleration request or braking operation (step S8). A braking action is generated in the regenerative operation, and the electric motor 3 regenerates power only when the SOC of the battery is below a lower limit value (for example, 30%)("Yes" in step S2) in order to avoid the regenerative operation as far as possible. That is, the regeneration is not executed when there is a certain amount of power. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To avoid generation heat of an inverter by locking of a motor and to maintain driving of the motor. SOLUTION: When locking tendency is judged to exist in rear wheels 12RL and 12RR driven by the motor 4, braking force is given to the rear wheels 12RL or 12RR. If locking tendency occurs in the rear wheels 12RL or 12RR driven by the motor 4 when the vehicle advances into a deep snow path and a sand path and tires are buried in snow or sand, for example, braking force is given to the rear wheels 12RL or 12RR. Distribution of driving force transmitted from the motor 4 to the wheels of one side is eliminated by given braking force. Thus, whole driving force is distributed to the other wheels and driving force of the other wheels becomes larger than running resistance. Consequently, the rear wheels 12RL and 12RR are prevented from being locked. Heating of the inverter 3 due to locking of the motor 4 can be avoided and driving of the motor 4 can be maintained.
