Why does the front radar beep when there is nothing in front?

[DelRemington]

The reasons why the front radar beeps when there is nothing in front are as follows: 1. Sensor hole position and location: The sensor hole is too small or too tight, or it is installed on an iron or hard protective bar. 2. Foreign objects on the surface: There are attachments such as paint, snow blocks, or ice blocks on the sensor surface. 3. Poor sensor characteristics, or the working environment temperature is too low. 4. Sensor failure. Here is some relevant information: 1. Reversing radar: The full name of the reversing radar is reversing anti-collision radar, also known as a parking assist device. It is a safety assist device for parking or reversing a car, consisting of ultrasonic sensors (commonly known as probes), controllers, and displays (or buzzers). 2. Function: It can inform the driver of the surrounding obstacles through sound or a more intuitive display, relieving the driver's troubles caused by looking around when parking, reversing, or starting the vehicle, and helping the driver eliminate blind spots and blurred vision defects, thereby improving driving safety.
