Beru f1Systems’ New Truck TPMS

With all eyes on green issues at the moment, Beru f1Systems is pointing out that tyres are the second or third largest expense for most truck fleet operators. Tests by tyre manufacturers have shown that under-inflation by 15 per cent reduces fuel economy by 2.5 per cent. Incorrectly inflated tyres also wear faster and are more prone to premature failure. That’s where BERU f1systems’ new Truck Tyre Pressure Monitoring System (TPMS).

The new system has been engineered specifically for the challenges of tyre pressure monitoring on large, multi-wheeled vehicles operating in fast-moving logistics environments. It 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 5 seconds and transmits the status of the tyre wirelessly to antennae mounted on the vehicle, once every 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 from Beru f1systems. These compact, rugged units allow technicians to see information about a particular tyre in a clear, easy to read format.

“Trucks are a tough environment for TPMS systems,” says 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 Truck 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 vehicle sector.”

Tyre pressure monitoring is becoming increasingly common as fleet operators try to reduce tyre wear and maintain highest possible fuel efficiency. Legislation is also leading manufacturers and operators to fit robust solutions. Beru f1systems’ Truck TPMS will operate with either 12 or 24v electrical architectures and can be installed as a standalone system, or integrated into the vehicle using its CAN data communication network.
