Abstract
A method for monitoring a ground clearance beneath a motor vehicle is disclosed. On the underbody of the motor vehicle, a plurality of ultrasonic transceivers are arranged spaced apart from one another. The method includes sending a transmission signal from a first ultrasonic transceiver, receiving a reflected transmission signal with a second ultrasonic transceiver, repeating the sending and receiving steps, determining a profile of a ground beneath the vehicle based on the echo signals, and determining a minimum ground clearance by comparing the ground profile with the underbody profile of the motor vehicle. Different pairs consisting of a first and a second ultrasonic transceiver are selected to receive a respective echo signal.

A method for monitoring a ground clearance beneath a motor vehicle, wherein, on the underbody of the motor vehicle a plurality of ultrasonic transceivers are arranged spaced apart from one another, the method comprising:
- selecting a first ultrasonic transceiver from among the plurality of ultrasonic transceivers and activating the first ultrasonic transceiver to send a transmission signal;
- selecting a second ultrasonic transceiver from among the plurality of ultrasonic transceivers and activating the second ultrasonic transceiver to receive a reception signal which is a reflection of the transmission signal;
- repeating selecting a first ultrasonic transceiver, sending a transmission signal, selecting a second ultrasonic receiver, and receiving a reflected signal,
- wherein different pairs consisting of a first and a second ultrasonic transceiver are selected to receive a respective echo signal;
- determining a profile of a ground beneath the motor vehicle on the basis of the received echo signals;
- and
- determining a minimum ground clearance beneath the motor vehicle by comparing the determined profile of the ground with an underbody profile of the motor vehicle.
