Problems solved by technology

[0002] With the continuous development and progress of automobile technology, people's demand for intelligent control of automobiles is getting higher and higher. At present, most of the back door control systems equipped with vehicles are composed of body controllers, back door control switches, and remote controls. More needs to be realized by external force, which is far from meeting people's demand for intelligent control of cars, and there is also a risk of pinching people when closing

Abstract

The invention discloses an anti-pinch system for a back door of an automobile and a control method thereof. An anti-pinch control module of the system can output a control signal to a back door lifting motor for controlling the back door to lift, and the anti-pinch control module is further connected with a vehicle body controller through a CAN (controller area network) bus and also connected with a back door control switch and a hall sensor for detecting whether an object is pinched or not. According to the system and the control method thereof, the back door can be effectively controlled, the anti-pinch system further has an anti-pinch function and an alarm prompt measure; and the system further has a motor protection function, so that the service life of the system is effectively prolonged.

Description

technical field [0001] The invention relates to the field of automobile electronic control, and more specifically relates to an automobile back door anti-pinch device. Background technique [0002] With the continuous development and progress of automobile technology, people's demand for intelligent control of automobiles is also increasing. At present, most of the back door control systems equipped with vehicles are composed of body controllers, back door control switches, and remote controllers. More needs to be realized by external force, which is far from meeting people's demand for intelligent control of cars, and there is also a risk of pinching people when closing. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize an automobile back door system with an anti-trap function and a control method thereof. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a...
