The new system was engineered specifically for large, multi-wheeled vehicles operating in fast-moving logistics environments and is capable of automatically detecting trailer changes and re-calibrating itself to keep the driver informed.
Sensors are fitted inside each wheel using a modified version of a standard valve. Each sensor measures tyre pressure and temperature every five seconds and transmits the status of the tyre wirelessly to antennae mounted on the vehicle, once a minute.
If a sensor detects a sudden change in pressure, it reports its status once per second, allowing the system to analyse the situation and alert the driver to potential problems. Up to six antennae can be fitted to the vehicle in order to ensure reliable data collection from all wheels, in all conditions.
To assist with routine maintenance, Truck TPMS is also compatible with hand held support tools. These allow technicians to see information about a particular tyre.

By GlobalData“Trucks are a tough environment for TPMS systems,” said senior application engineer, James Shingleton.
“Their large size makes optimum RF reception difficult, while the high number of wheels and frequent trailer changes create set-up and calibration challenges. On top of that, you have to add long operating hours in difficult conditions. To produce the TPMS we have taken all our experience of tyre pressure monitoring in motor sport, passenger car and bus applications and developed a new system specifically to meet the needs of the [heavy] vehicle sector.”
Beru said tyre pressure monitoring is becoming increasingly common as fleet operators try to reduce tyre wear and maintain highest possible fuel efficiency.
The truck TPMS will operate with either 12 or 24v electrics and can be installed as a stand-alone system, or integrated into the vehicle using its CAN data communication network.
