Car back detection device capable of preventing accidental overtaking collision

Abstract

The invention relates to a car back detection device capable of preventing accidental overtaking collision, which is arranged on an automobile and comprises a plurality of ultrasonic wave sensors, animage camera at the back of the automobile and a control host, a vehicle-mounted display and an alarm module, wherein, the control host calculates the distance value of the barrier according to flighttime of the ultrasonic wave signals, and judges whether an object move to the automobile in a high speed or not from the shot image signals by the image camera at the back of the automobile; the vehicle-mounted display displays the images captured from the image camera at the back of the automobile and the distance value of the barrier calculated by the control host; and the alarm module gives out alarm voice when the control host judges that an object move towards the automobile in a high speed. The car back detection device can lead users to fully learn the distance of the back of the automobile and barriers, and matches to detect whether objects move towards the back of the automobile in a high speed, and can effectively prevent accidental collision.

Description

technical field [0001] The invention relates to a backing detection device, in particular to a backing detection device capable of preventing collision accidents. Background technique [0002] In order to assist the driver to reverse and park safely, the rear end of the vehicle is generally equipped with a reversing radar, which can use the principle of ultrasonic reflection to judge whether there is an obstacle behind the car during the reversing process, and send out different alarm sounds to alert the driver. Know the distance between the rear of the car and the obstacle; even, a camera is installed on the rear end of a higher-grade vehicle, and a display connected to the camera is provided in the car to transmit the rear image captured by the camera The monitor in the car allows the driver to watch the situation behind the car. [0003] However, the above-mentioned reversing detection device does not allow the driver to know the relative relationship between the rear of...

AI Technical Summary

Problems solved by technology

Therefore, when the vehicle is reversing, the obstacle moving in the opposite direction cannot be detected and issued an alarm until it enters the ultrasonic detection range, otherwise danger will easily occur.

[0005] This shows that above-mentioned existing reversing detection device obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
