Patent ID: 8073577

Claim:
An electrical control apparatus mounted on a vehicle having a height direction, said apparatus comprising: an electric circuit board that has a mounting surface and that is mounted in the vehicle so that the mounting surface is along the height direction of the vehicle; a submersion sensor that is mounted on the mounting surface of the circuit board and senses a condition that the vehicle is about to be submerged in a flooded area and outputs an electric signal showing the condition; a controller that is mounted on the mounting surface of the circuit board and performs control for securing safety of an occupant of the vehicle when the controller receives the electric signal from the submersion sensor, wherein the submersion sensor is lower in a mounted position on the mounting surface of the circuit board than the controller along the height direction; and a power supply that is mounted on the mounting surface of the circuit board such that the power supply is positionally higher than the controller in the height direction of the vehicle, converts a voltage of a power supply of the vehicle into an internal voltage available to components on the circuit board, and supplies the components with the internal voltage, the components including the detector and the controller, wherein the submersion sensor, the controller, and the power supply are aligned from a front of the vehicle in an order advancing from the submersion sensor to the power supply via the controller.
