Claims

[Scope of utility model registration request]

In a vehicle in which a vehicle height adjustment mechanism is provided between a wheel support member that supports a wheel and a vehicle body member above the vehicle height adjustment mechanism, the upper and lower limit positions of the vertical stroke of the vehicle height adjustment mechanism are detected and an upper limit signal and a lower limit signal are generated, respectively. A position sensor that emits a signal is provided, and two photocouplers, a first and a second photocoupler are arranged in parallel on the vehicle body member, and a point on the extension of the line connecting the first and second photocouplers is set as the rotation center. a large-diameter circular arc portion that is rotatably attached to the vehicle body member and rotates in conjunction with vertical displacement with respect to the wheel support member, and that blocks the optical paths of both the first and second photocouplers; A vehicle height sensor is formed by combining a disc-shaped shutter in which a medium-diameter circular arc portion that blocks only the optical path of the photocoupler and a small-diameter circular arc portion that does not block both the first and second optical paths are formed on the circumference. and operate the vehicle height adjustment mechanism from the upper limit position to the lower limit position and from the lower limit position to the upper limit position from the position sensor signal of the vehicle height adjustment mechanism and the signal of the vehicle height sensor under the condition that the vehicle speed is high. 1. A vehicle height control device for an automobile, comprising a vehicle height control circuit that emits a signal.
