Problems solved by technology
[0013] That is, if a map matching method based on a GPS navigation system including a three-dimensional gyroscope device is to be used, it is necessary to add a three-dimensional gyroscope sensing system and other computing systems to the vehicle.
[0014] At the same time, since each system is configured independently, it takes up a lot of space compared to the effect of providing accurate map matching, and increases the purchase cost
[0015] Moreover, each of the above-mentioned systems functions independently, and the driver of the vehicle needs to monitor each system, which hinders safe driving.

The invention discloses a map matching system and method using a tire pressure automatic monitoring system (TPMS), specifically disclosing that by detecting the variation of front and rear tire pressures received from the tire pressure automatic monitoring system, judging the inclination of the vehicle and the inclination running and No, a system and method for improving the accuracy of map matching on elevated roads and the like. The map matching system based on changes in tire pressure includes: an automatic tire pressure monitoring system unit, which monitors the tire pressure of the front wheels and rear wheels; a tire pressure receiving unit, which receives the tire pressure of each wheel from the tire pressure automatic monitoring system unit; The pressure change detection unit receives the tire pressure and judges whether the vehicle is running on a slope by referring to the change amount of the tire pressure. The present invention can improve the advantages of map matching accuracy, and at the same time, can obtain the effect similar to the map matching by three-dimensional gyroscope.
Description
technical field [0001] The present invention relates to a map matching system and method using a tire pressure automatic monitoring system (Tire Pressure Monitoring System; hereinafter referred to as TPMS), in particular to monitoring the pressure changes of front wheels and rear wheels received from the tire pressure automatic monitoring system A system and method for improving map matching accuracy on roads with varying heights by judging the inclination of a vehicle and whether it is running on an incline. Background technique [0002] Conventionally, a navigation system (Navigation System) equipped with a Global Positioning System (Global Positioning System, GPS) is used in order to confirm the current position and moving speed of the vehicle, or to determine the moving route. [0003] The vehicle navigation system receives radio waves indicating latitude, longitude, and altitude transmitted from a plurality of artificial satellites, and calculates the current position i...
