AI Technical Summary

Technical Problem

Existing on-vehicle water wading detection solutions are easily interfered with by obstacles, resulting in detection failure or false alarms, affecting the reliability of water wading detection.

Method used

Multiple groups of ultrasonic sensors located at different heights are used, each group includes a transmitting end and a receiving end. By analyzing the aftershock curve and impedance curve of the envelope signal, the medium penetration of the ultrasonic signal during the propagation process is judged, the wading condition is determined, and an early warning is issued when the wading height exceeds the preset value.

Benefits of technology

The reliability of vehicle wading detection is improved, ensuring that the wading status can still be accurately identified even when there are obstacles, reducing the risk of misjudgment and providing timely warning information.

Abstract

The invention discloses a vehicle wading early warning method and device based on an ultrasonic sensor, terminal equipment and a storage medium, belongs to the field of vehicle safety and is suitable for a vehicle, a plurality of sensor groups located at different heights are arranged on the vehicle, and each sensor group comprises an ultrasonic sensor sending end and an ultrasonic sensor receiving end; the method comprises the following steps: for each sensor group, acquiring an envelope signal measured by a receiving end of an ultrasonic sensor; determining an aftershock curve and an impedance curve according to the envelope signal; determining a medium crossing condition according to the aftershock curve and the impedance curve, and determining a wading condition of the ultrasonic sensor according to the medium crossing condition; according to the heights of all the ultrasonic sensors in the wading state, the wading height is determined, and when the wading height exceeds a preset height, wading early warning is given out. According to the vehicle wading detection method and device, the problem that existing vehicle-mounted wading detection is prone to being interfered by obstacles can be solved, and the reliability of vehicle wading detection is improved.
