Description

technical field

[0001] The invention relates to the technical field of automotive electronic vehicle products, in particular to a tire pressure monitoring and alarm system based on CAN bus and K line communication. Background technique

[0002] During the high-speed driving of a car, tire failure is the most worrying and difficult to prevent for all drivers, and it is also an important reason for sudden traffic accidents. At present, the car accidents caused by blown tires occupy the top of the list of expressway accidents, and blown tires have become one of road traffic killers. According to statistics, 70% of traffic accidents on Chinese expressways are caused by blown tires, while in the United States this ratio is as high as 80%. How to prevent tire blowout has become an important topic for safe driving. According to the expert analysis of the National Rubber Tire Quality Supervision Center, maintaining the standard tire pressure for driving and timely detection of tir...
