The invention relates to a method for monitoring a ground clearance below a motor vehicle (1), on the underbody (2) of which a plurality of ultrasonic transceivers (101-109) are arranged at a distance from one another, comprising the following steps: a) selecting (S1) a first ultrasonic transceiver from the ultrasonic transceivers (101-109) and activating the first ultrasonic transceiver to transmit a transmission signal; b) selecting (S2) a second ultrasonic transceiver from among the ultrasonic transceivers (101-109) and activating the second ultrasonic transceiver (101-109) to receive a received signal as a reflection of the transmission signal transmitted in step (a); c) repeating (S3) steps a) and b), wherein various pairs consisting of the first and second ultrasonic transceivers (101-109) are selected to receive the corresponding echo signals; d) determining (S4) a ground profile below the motor vehicle (1) on the basis of the received echo signals; and e) determining (S5) a minimum ground clearance (9) below the motor vehicle (1) by comparing the contour of the ground surface (6) with the underbody contour of the motor vehicle (1).
本发明涉及一种用于监测机动车辆(1)下方离地间隙的方法,在机动车辆的车身底部(2)上布置有彼此间隔开的多个超声波收发器(101‑109),该方法包括以下步骤:a)从超声波收发器(101‑109)中选择(S1)第一超声波收发器并激活第一超声波收发器以发送传输信号;b)从超声波收发器(101‑109)中选择(S2)第二超声波收发器并激活第二超声波收发器(101‑109)以接收作为在步骤(a)中发送的传输信号的反映的接收信号;c)重复(S3)步骤a)和b),其中选择由第一和第二超声波收发器(101‑109)构成的各种对以接收相应的回波信号;d)基于接收的回波信号确定(S4)机动车辆(1)下方的地面轮廓;以及e)通过将地面(6)轮廓与机动车辆(1)的车身底部轮廓进行比较来确定(S5)机动车辆(1)下方的最小离地间隙(9)。
