Integrated Vehicle Tyre Monitoring Launched

A co-operation between Michelin and Wabco sees the launch of a tyre pressure monitoring system specifically designed for commercial vehicles. The system consists of wheel modules which measure tyre inflation pressure and transmit the data to a vehicle mounted receiver. In the event of pressure loss the data is sent several times every minute.

The module is attached to the outside of the wheel, alleviating many of the problems associated with internal sensors. An Electronic Control Unit (ECU) capable of handling up to 12 wheels is mounted on the vehicle chassis. In the case of trailer units, each trailer has its own ECU.

The ECU transmits the signals to a cab mounted display unit which alerts the driver visually and acoustically whenever a problem arises. The position of the faulty tyre can be ascertained by pressing a button on the display. The system has the advantage of an evaluation algorithm developed by Michelin which detects pressure deviations and leakages immediately.

It even functions whilst the vehicle is stationary. The system can be retrofitted and will be commercially available in Europe by the middle of 2002..
