How many types of tire pressure monitoring methods does the new Wuling Hongguang S have?

The new Wuling Hongguang S has three types of tire pressure monitoring methods. Tire pressure monitoring is an automatic real-time monitoring of tire pressure during vehicle operation, which alerts the driver in case of tire leakage or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts the driver when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. The indirect tire pressure alert system essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): This system combines the advantages of both the above-mentioned systems. It is equipped with direct sensors in two diagonally opposite tires and an indirect system for all four wheels. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of the indirect system, which cannot detect low pressure in multiple tires simultaneously. However, it still cannot provide real-time pressure data for all four tires like a direct system.
I recently researched the tire pressure monitoring system (TPMS) of the new Wuling Hongguang S and found that this model generally comes with two monitoring methods: one is indirect, which uses ABS wheel speed sensors to analyze vehicle speed and tire rotation differences to estimate tire pressure, while the other, possibly available in some higher-end versions, features direct sensors installed inside the tires to measure pressure directly. The indirect method is simpler to maintain and lower in cost but occasionally has larger errors; the direct method is more accurate and stable. While driving, the dashboard will display a warning light to alert you of any tire pressure issues. It is recommended that owners manually check tire pressure with a gauge once a month to avoid risks of leaks or blowouts, improving both safety and cost-effectiveness.
