example 1

[0021] Example 1: if figure 1 , figure 2 As shown, it is characterized in that: the vehicle-mounted radar 1 is symmetrically installed in the doors on both sides of the car, the speed sensor 5 is installed in the center of the rear of the car, the displacement sensor 4 is symmetrically installed on both sides of the rear of the car, and the rotational speed sensor 3 is symmetrically installed in the rear of the car. On the rear wheel; the input end of the data processing unit is connected to the output end of the information collection unit; the input end of the safety warning unit is connected to the output end of the data processing unit; the red LED strobe warning of the safety warning unit Lamp 2 is symmetrically installed on the inner sides of both sides of the doors.

[0022] The vehicle radar 1 is an ultrasonic radar.

[0023] The execution control of the safety early warning unit is composed of LED red strobe warning lights 2, automobile tail lights and a multi-voic...

example 2

[0024] Example 2: The working process of an automobile door opening anti-collision system of the present invention is as follows.

[0025] 1. The system detects that the wheel speed is less than or equal to 1r / min through the speed sensor 3 installed on the wheel, and at the same time receives the central control unlock command before starting the power supply and starting to work normally, thus meeting the need for passengers to get off the car under normal circumstances. Preparing conditions to avoid misjudgment of the occupant's intention to get off the vehicle by the system.

[0026] 2. When the system detects that there is a stationary obstacle within 1.3m of a certain side door (the edge of the door is about 1.1m away from the body when the door is fully opened) through the ultrasonic vehicle-mounted radar 1 installed on both sides of the vehicle door, the safety warning unit opens the side door. The LED red strobe warning light 2 on the inner side of the door will give ...

Abstract

The invention discloses an automobile door opening anti-collision system, which relates to the technical field of automobile safety. The system comprises an information acquisition unit, wherein the information acquisition unit is used for obtaining the door opening action and the monitoring of obstacles around the vehicle body, as well as the relative driving speed and distance between the vehicle body and the rear vehicle; A data processing unit, wherein an input end of the data processing unit is connected with an output end of the information acquisition unit; And a safety early warning unit, wherein an input end of the safety early warning unit is connected with an output end of the data processing unit. The system can effectively avoid vehicle collision accidents caused by rear vehicle dodging due to passengers getting off and opening the vehicle door, improve driving safety, and enhance the intelligent and integrated level of vehicle door control.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile door opening anti-collision system. Background technique [0002] With the continuous increase of the number of automobiles in our country, the traffic safety of vehicles has attracted more and more attention. When the passenger intends to stop the car and get off, if he fails to observe the moving objects such as motor vehicles, bicycles or stationary obstacles on both sides of the door and the front and rear in time, the passenger will get off the car rashly, which will make the two sides of the door Collision between the front and rear moving objects and the car door, or the collision between the car door and surrounding obstacles will not only cause economic losses such as vehicle damage, but may lead to serious casualties in severe cases. Thereby, how to guarantee the safety of the passenger after opening the car door and avoiding the occurrence of t...
