Claims

[Claims for Utility Model Registration] A transmitter that transmits ultrasonic pulses toward a road surface; A receiver that receives reflected waves from which the transmitted waves are reflected on the road surface; Transmission timing of the transmitted waves and the reflection. a vehicle height calculation means that outputs vehicle height data based on a time difference with a wave reception timing; when the time difference is a value outside a preset range from a minimum time difference to a maximum time difference, a vehicle height calculation means that outputs vehicle height data based on a time difference with a wave reception timing; A vehicle height detection device comprising: prohibition means for prohibiting output of the vehicle height data.
