Under pressure

The introduction of tyre pressure monitoring systems (TPMS) in the USA and Europe is discussed. The implementation in the USA of direct TPMS and subsequent switch to indirect TPMS is described. The advantages of indirect TPMS are examined. As well as being cheaper for manufacturers to install and not being reliant on batteries or electronics, indirect TPMS is easier to operate by the driver and can be reset to adapt to changes to the vehicle such as changes from winter to summer tyres and changes to rims. These changes can be accommodated by indirect TPMS whereas direct TPMS would require new sensors. The role of legislation, in particular in relation to the integration of ESC, is considered. A brief description is given of NIRA Dynamics' TPI system which can easily be integrated into the vehicle bus system.
