PROBLEM TO BE SOLVED: To provide a technique for detecting the flooding at a relatively low cost, in the flood measures of an on-vehicle inverter arranged in a recess.SOLUTION: An electric vehicle can select two-wheel drive and four-wheel drive, and includes a main motor for running used in two-wheel drive, and a submotor driven auxiliarily for supplementing the running torque and used in four-wheel drive. The electric vehicle includes a recess provided in the floor panel, a main inverter for supplying power to the main motor, and a sub-inverter arranged in a recess and supplying power to the submotor. An air-cooling fan for cooling the sub-inverter is also arranged in the recess. A controller included in the electric vehicle stops the sub-inverter when the number of revolution of the air-cooling fan exceeds a predetermined threshold NB2. |
