<p>PROBLEM TO BE SOLVED: To provide a submersion detector for automobile, capable of facilitating the escape of an occupant from the inside of an automobile by detecting falling of an automobile into the sea or the like, thus automatically opening a window, unlocking a door, and releasing a seatbelt. SOLUTION: A pressure sensor 1 capable of measuring water pressure is mounted below the engine of an automobile, and the signal of the pressure sensor 1 is inputted into a controller 8. The controller 8 is constituted of an amplifier 2 amplifying the inputted signal, a comparator 3 comparing the amplified signal with a reference value and outputting it when it is higher than the reference value, and a relay drive device 4 into which the signal of the comparator 3 is inputted. The respective gates of the field-effect transistors 4a, 4b, 4c forming the device 4 are connected respectively to the comparator 3, their drains are connected to a battery source (B), and their sources are connected respectively to a door lock unit 31, a power window unit 21, and a belt release unit 41.</p> |
