Abstract

The invention discloses a method and a device for opening and closing an automobile tire pressure monitoring system, belonging to the field of automobile electronics. The method includes signally connecting the diagnostic tool with the electronic control unit of the vehicle, and according to the configuration information of the tire pressure monitoring function of the control module, when it is determined that the tire pressure monitoring function of the control module exists and the tire pressure monitoring function of the display module exists, the tire is turned on. When the diagnostic tool modifies the tire pressure monitoring function of the control module to non-existent and the tire pressure monitoring function of the display module to non-existent, the tire pressure monitoring system is turned off to realize the low-end models that are not equipped with the tire pressure monitoring system. After the tire pressure monitoring system is installed, or the tire pressure monitoring system of the high-profile model equipped with the tire pressure monitoring system fails, the tire pressure monitoring system needs to be turned on when after-sales maintenance is required, or the tire pressure monitoring system that the customer needs to temporarily turn off the tire pressure monitoring function is turned off. , to avoid the separate configuration of related modules, improve the efficiency of after-sales maintenance, and meet customer needs.

Description

technical field [0001] The invention belongs to the field of automobile electronics, in particular to a method and device for opening and closing an automobile tire pressure monitoring system. Background technique [0002] With the development of society, traffic safety has become a worldwide problem, and the impact of automobile safety on human life and property is self-evident. With the advancement of automobile technology, the safety of automobiles has also been refined. Traditional passive safety is far from being able to avoid traffic accidents. Therefore, active safety has been paid more and more attention by everyone. As an active safety technology, the tire pressure monitoring system has been widely used in foreign countries, and domestic OEMs have also equipped the tire pressure monitoring system on high-end models. [0003] In the prior art, the relevant modules of the tire pressure monitoring system of a car equipped with the tire pressure monitoring system are i...
