とを特徴とする全輪駆動車における駆動系切替誤
操作防止装置。[Claims for Utility Model Registration] An all-wheel drive vehicle equipped with a freewheel hub, which shifts the drive system between two-wheel drive and all-wheel drive by an actuator operated by an electric signal, and the actuator In an all-wheel drive vehicle in which the operation of the freewheel hub is performed by a changeover switch, a state detection device is provided to detect whether the freewheel hub is in a free state or a locked state, and a state detection device is provided between the changeover switch and the actuator to prevent erroneous operation. A switch is provided, and when the freewheel hub is determined to be free by the state detection device while the vehicle is running, the erroneous operation prevention switch is activated, and while the erroneous operation prevention switch is in operation, the changeover switch is activated. A drive system switching erroneous operation prevention device for an all-wheel drive vehicle, characterized in that even if operated, the actuator does not operate, making it impossible to shift from two-wheel drive to all-wheel drive.
