  • Electrical circuit arrangement for controlling an electromotor in a motor vehicle
    Patent number: 7282817
    Abstract: A motor control arrangement includes a device connected to positive power such that device drives motor upon connecting to negative power. A switch connects to positive power upon actuation. A first transistor connects to switch via controller and connects between device and negative power. First transistor turns on causing device to connect to negative power upon switch actuation while controller is operational. A second transistor connects to switch and connects between device and negative power when controller is malfunctioned. Second transistor turns on causing device to connect to negative power upon switch actuation while controller is malfunctioned. A sensor connects to negative power upon contact with water. A third transistor connects to switch and sensor such that its collector-emitter path is connected in parallel to device.
