An inspection method of the present invention performs a step of giving the electric motor an instructing for rotating a foot shaft in a reverse direction and checking whether the foot shaft is rotating in the reverse direction, and a step of checking whether hydraulic pressure acting on the hydraulic pump has reached a predetermined pressure level. By checking a rotating direction of the electric motor, it is possible to check electrical connections. By checking the hydraulic pressure, it is possible to check whether there is any trouble in a hydraulic system. Namely, the present invention can perform an electrical connection check and a hydraulic pressure check in a collective fashion.

Inspection method for inspecting electric drive apparatus

In the case where a difference between rotational speeds of right and left wheels detected by wheel speed sensors is less than a predetermined value, a right and left wheel power transmission control section distributes driving force between the right and left wheels so that a total value of the driving force of the right and left wheels does not exceed a limit value set up by a front and rear wheels power transmission control section. In the case where the difference between the rotational speeds of the right and left wheels is the predetermined value or more, the right and left wheel power transmission control section transmits the driving force up to a driving force upper limit for each wheel to the respective right and left rear wheels regardless of the total value of the driving force of the right and left rear wheels.
