The invention provides a preview road surface detection device capable of suppressing confusion reception of detection waves transmitted from a plurality of transmitters. In order to solve the problem, the present invention provides a preview road surface detection device comprising: a distance sensor which is provided with a plurality of transmitters and at least one receiver, which face in a direction intersecting the direction of travel of a vehicle and are attached in parallel to a vehicle body member, so as to detect a value relating to the distance between the vehicle body member and a measurement point on a road surface in front of the vehicle; the measuring point corresponds to at least one part of a road surface grounding part of the wheel; and a distance calculation unit that calculates a road surface distance, which is the distance between the vehicle body member and the measurement point, on the basis of a detection value detected by the distance sensor. Wherein the transmitter transmits the detection wave in a manner having a time difference with an adjacent transmitter.
本发明提供一种预览路面检测装置,其能够抑制从多个发送机发送的检测波被混淆接收的情况。为了解决上述问题,提供一种预览路面检测装置,具备距离传感器,其具备朝向与车辆的行进方向相交的方向且并列安装在车身部件上的多个发送机和至少一个接收机,以检测车身部件与车辆前方的路面的测量点之间的距离相关的值,该测量点对应于车轮的路面接地部的至少一部分;及,距离计算部,其基于由距离传感器检测到的检测值,来计算车身部件与测量点的距离即路面距离;其中,发送机以与相邻的发送机具有时间差的方式发送检测波。
