Tire Pressure monitoring System
The Tire Pressure Monitoring System measures and gives feedback of tire pressure of a vehicle. A MIL (Malfunction Indicator Light) will go off on the dashboard instrument panel if one or more tires on a vehicle contains an undesirable amount of air pressure which could lead to unsafe driving conditions. Tire pressure affects steering precision as well as braking of vehicles, one of the two most safety impacting driving parameters. Tire pressure calibration and monitoring is therefore an indispensable responsibility that every driver should take on. Thanks to modern technology, constant monitoring and fault detection can be managed by use of TPMS Sensors in conjunction with the onboard vehicle computer.
Tire air pressure has a direct relation to fuel economy as well. Under-inflated tires result in poor fuel economy as some acceleration power will be dumped to the increased frictional forces between the road and the large surface area it is in contact with. There are two main types of TPMS based on the method used to acquire the information of the tire air pressure.
