Automobile door opening danger early warning device

Abstract

The invention discloses an automobile door opening danger early warning device. The safety early warning device is composed of a distance sensor, an early warning device, an electromagnetic controllerand a processing chip which are electrically connected with one another, wherein the distance sensor is installed in an automobile rearview mirror, the energy wave beam emitting direction of the distance sensor forms an included angle of 1 degree outwards in the X coordinate line + direction of an automobile, and energy wave beams are emitted to the rear portion of the automobile. When the distance sensor in the automobile rearview mirror detects the distance between the distance sensor and an obstacle on the rear side, a signal is transmitted to the processing chip, the processing chip compares the distance with a preset value and sends an electric signal to the electromagnetic controller, and the electromagnetic controller controls the early warning device to send out different early warning signals. Therefore, the passenger can be effectively assisted in judging whether the door is opened or not.

Description

technical field [0001] The invention belongs to the field of automobile safety, and in particular relates to an early warning device for the danger of opening a door of an automobile. Background technique [0002] In recent years, the number of road vehicles in our country has increased day by day, and traffic accidents have also occurred frequently. A large part of the traffic accidents occurred at the moment when the car stopped and the door was opened. Observation, thus making it impossible for passengers in the car to determine the safety of opening the door and getting out of the car. At present, although the automotive industry has made great improvements in terms of safety, the installation of auxiliary driving equipment such as radar or panoramic cameras on cars has made great improvements in active safety and passive safety, but in terms of safety when opening the side door It's still almost blank. There are also some technologies that use the method of machine vi...

[0002] In recent years, the number of road vehicles in our country has increased day by day, and traffic accidents have also occurred frequently. A large part of the traffic accidents occurred at the moment when the car stopped and the door was opened. Observation, thus making it impossible for occupants in the vehicle to be sure that it is safe to open the door and get out of the vehicle

At present, although the automotive industry has made great improvements in terms of safety, the installation of auxiliary driving equipment such as radar or panoramic cameras on cars has made great improvements in active safety and passive safety, but in terms of safety when opening the side door almost blank

There are also some technologies that use the method of machine vision to monitor the side and rear vehicle conditions to achieve the purpose of safety, but due to the high cost, it is not suitable to be applied to every car, and the cost performance and practicability are average.
