Popis: |
Tire pressure monitoring systems (TPMSs) have become almost a commodity in all vehicle segments. Current and upcoming legal requirements will further enhance the market penetration of TPMS. Two different pressure-monitoring principles are available as there are direct and indirect systems. Direct systems place, in each wheel, a sensor that measures pressure and temperature. Indirect systems use sensor fusion to generate pressure loss information from the wheel speed signals. This chapter describes the importance of the correct tire pressure and the history of TPMSs. It presents in detail the working principle of state-of-the-art direct and indirect systems as well as the current legal requirements that need to be fulfilled when designing tire pressure-monitoring systems. The last section not only focuses on customer requirements and aftermarket topics but also gives an outlook on future developments and trends in the field of tire pressure monitoring. Keywords: direct measuring system; diffusion detection; indirect measuring system; puncture detection; tire blow out; TREAD act; under inflation warning; wheel unit; wheel radius analysis; wheel spectrum analysis |
