Why does the Golf 7 Driving Computer show that the tires are easy to slip?

The driving computer shows that the tires are easy to slip, that is, the temperature sensor detects that the outdoor weather is too low and the road surface is afraid of freezing, reminding the owner not to slip, which affects driving safety.

Tire monitoring methods for motor vehicles;

1. Direct tire pressure monitoring: The networked tire pressure monitoring device directly measures the tire pressure by using the pressure sensor installed in each tire, sends the pressure information inside the tire to the central receiving module by using the wireless transmitter, and then displays the tire pressure data. When the tire pressure is too low or leaks, the system will automatically give an alarm.

2. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is that when the air pressure of a tire decreases, the rolling radius of the wheel will decrease due to the weight of the vehicle, resulting in its rotating speed being faster than other wheels. By comparing the speed difference between tires, tire pressure can be monitored. The indirect tire warning system actually monitors the air pressure by calculating the tire rolling radius.

3. Introduction of Tire Intelligent Monitoring System (TPMS): It has the advantages of the above two systems. It is equipped with two direct sensors in diagonal tires and a four-wheel indirect system. Compared with the direct system, this composite system can reduce the cost and overcome the shortcoming that the indirect system can not detect the low air pressure of multiple tires at the same time. However, it still can't provide real-time data of actual pressure in all four tires like the direct system.
