- 摘要：
This road surface detection sensor (100) is provided with: an ultrasonic sensor that transmits ultrasonic waves towards a road surface (31), and receives reflected waves from the road surface (31); and a reflecting surface (20) positioned facing the road surface (31), for bringing about repeated reflection of ultrasonic waves with respect to the road surface (31). The acoustic pressure of each of a first reflected wave through an n-th reflected wave from the road surface (31) is compared with a reference acoustic pressure corresponding to the reflected wave, and the type of road surface (31) is determined. In so doing, there is provided a road surface detection sensor with which the type of any of various road surfaces, such as those including bumpy pavement surfaces, can be determined.
