ABSTRACT:
A collision detection device is provided which is effective for improving the detection quality for detection of displacement of a vehicle component during a vehicle collision. In one form, the collision detection device to be installed in a vehicle comprises a coil sensor. The coil sensor includes a first coil which is arranged to face a door outer panel and a second coil which is arranged near the first coil and inside the outer diameter of the first coil and centered about a line perpendicular to the coil plane of the first coil. The coil sensor detects information about induced voltage due to magnetovariation via the second coil when the door outer panel is located in a distant region and detects information about variation in impedance via the first coil when the door outer panel is located in an adjacent region.
