Intelligent anti-pinch system and method for automobile door

Abstract

The invention relates to an intelligent anti-pinch system for an automobile door. The intelligent anti-pinch system for the automobile door comprises a vehicle-mounted control system, a vehicle-mounted voice output device and a laser detection device, and the vehicle-mounted control system is in communication connection with the vehicle-mounted voice output device and the laser detection device; the laser detection device comprises a laser signal transmitting device and a laser signal receiving device, the laser signal transmitting device is arranged on an automobile door frame body, and the laser signal receiving device is arranged on the inner side of the automobile door and used for receiving laser signals transmitted by the laser signal transmitting device in real time and transmittingthe laser signals to the vehicle-mounted control system; and the vehicle-mounted control system is used for judging whether foreign matter exists between the automobile door frame body and the automobile door or not according to the received laser signals and reminding a driver through the vehicle-mounted voice output device. According to the intelligent anti-pinch system for the automobile door,the driver reacts quickly when the anti-pinch system reminds the driver; and in addition, the vehicle-mounted control system can decrease the speed of the automobile door closing action through an air cylinder, and more reaction time is provided for the driver.

Description

technical field [0001] The invention provides an anti-pinch technology for a vehicle door, and in particular relates to an intelligent anti-pinch system and method for an automobile door. Background technique [0002] As one of the means of transportation in modern cities, cars have quickly become the main means of travel for people due to their advantages of speed and convenience. However, while the development of automobiles brings convenience to people's lives, it is not uncommon for automobile doors to pinch items or even hurt people. The main reason is that drivers or passengers often forget to detect whether there are foreign objects in the car door and directly close the car door. Of course, some accidents are caused by other people outside the car accidentally relying on the car door. When the clothes or belongings are caught by the car door, if the driver cannot find out in time or make a correct response quickly after finding out, it may cause injuries to passenge...

When the clothes or belongings are caught by the car door, if the driver fails to find out in time or make a quick and correct response after finding out, it may cause injuries to passengers or other personnel

[0003] At present, there are three main types of anti-pinch technology for automobile doors on the market: the first is electronic delay anti-pinch technology, which has a simple structure and low cost, but the response is not sensitive enough and the anti-pinch effect is not ideal; The first is the anti-trap technology of the airbag. This anti-trap technology mainly generates an anti-trap signal by monitoring the movement of the airflow inside the rubber strip. Widely promoted; the third is the air pressure switch anti-pinch technology, which has a simple structure and low cost, but the monitoring exhaust pressure value is fixed and the reliability is low
