Tire Pressure Monitoring System (TPMS)
What is TPMS?
TPMS stands for Tire Pressure Monitoring System. It is an automotive safety system designed to monitor and provide real-time information about the air pressure of a vehicle’s tires.
The primary purpose of TPMS is to alert the driver when the tire pressure in any of the tires is significantly under-inflated, as this can lead to safety issues and reduced fuel efficiency.
Types of TPMS
- This system uses pressure sensors located in each tire, which directly measure the tire pressure.
- The sensors send this information to a central control unit, which processes the data and alerts the driver if it detects low tire pressure.
- This system does not use pressure sensors in the tires but instead relies on the vehicle’s existing sensors, such as the anti-lock braking system (ABS) sensors, to indirectly monitor tire pressure.
- Indirect TPMS analyzes the rotational speed of each wheel and can infer changes in tire pressure based on variations in wheel speed.
