In recent years the automobile industry has been adopting ever-higher safety standards. Under this light, the development of a tyre pressure monitoring system that aims to overcome the difficulties faced by the already present systems becomes even more important. In order to meet that specific need, a system which is capable of relaying the status of tyre pressure from a sensor at the wheel to a display unit in the vehicle cab was constructed. This new system employs the CAN bus network technique, as well as a novel method of relaying the tyre pressure status off the wheel without using any power or transmitter system, thus overcoming many of the obstacles faced by systems of the same scope. The purpose of this paper is to give an account of the in-field trials performed in order to assess the behaviour of the system in a ‘real world’ environment.
