The sensors are arranged at the rear of the special vehicle chassis, specifically: 2 ultrasonic sensors are located outside the top of the two tail lights; In the planar multi-radar reversing detection system described in the utility model, eight ultrasonic sensors are arranged at the tail of the special vehicle chassis. Such arrangement is beneficial to eliminate the blind area in the width direction of the chassis, and can detect a certain area in the height direction.

Description

A planar multi-radar reversing detection system

technical field

The utility model belongs to the technical field of reversing radar systems, in particular to a planar multi-radar reversing detection system.

Background technique

The reversing radar system has been widely used in small passenger cars as a car safety device. The reversing radar mainly uses the principle of ultrasonic waves when reversing the car. The probe installed at the rear of the car sends ultrasonic waves to hit obstacles and then reflects the sound waves, thereby calculating the actual distance between the car body and obstacles, and prompting the driver. To protect, make parking and reversing easier. In actual operation, the reversing radar system controls the buzzer to sound at different frequencies according to the distance of obstacles entering the detection area to warn the driver. The closer the obstacle, the higher the beep frequency.

The structure of special vehicles has its own particularity. On the one hand, the car body is wide, and the range covered by a single reversing radar is limited, and there are too many blind spots; on the other hand, although the reversing radar is installed at the rear of the chassis, the bodywork system often The tail basically extends out for a certain distance. At this time, the reversing radar must be able to identify its own bodywork system and rear obstacles, otherwise it will cause a false alarm and cause the driver to fail to make a correct judgment. Therefore, for special vehicles, a special reversing radar system is required.

Contents of the invention

The purpose of this utility model is to provide a planar multi-radar reversing detection system, which not only ensures that the entire vehicle section is covered without blind spots, but also can automatically identify its own bodywork system and rear obstacles, and can provide correct warning prompts to assist the driver in parking and reverse.

The technical solution to realize the purpose of this utility model: a plane multi-radar back-up detection system, the plane multi-radar back-up detection system is arranged on the chassis of a special vehicle, the bodywork system protrudes from the tail of the special-purpose vehicle chassis, and the plane multi-radar back-up detection The system includes 8 ultrasonic sensors, which are arranged at the rear of the special vehicle chassis, specifically: 2 ultrasonic sensors are respectively located on the outer top of the two tail lights; two ultrasonic sensors are respectively located in the middle of the outer sides of the 2 tail lights; 4 ultrasonic sensors are evenly distributed on the chassis Below the tail beam.

The effect of the utility model is that: in the planar multi-radar reversing detection system described in the utility model, eight ultrasonic sensors are arranged at the tail of the special vehicle chassis. a certain area. After program control, the planar multi-radar reversing detection system can automatically identify the bodywork system of special vehicles and provide accurate reversing warning prompts for drivers.
