Tyre pressure monitoring systems monitor the pressure inside the tyre and issue a warning when the tyre pressure falls below a defined threshold. Indirect tyre pressure monitoring systems (iTPMS) are based on the continuous evaluation of the pressure-dependent rolling radius and the pressure-dependent tyre vibration behaviour. Since the tyre itself thus serves as a sensor, an assessment of the tyre properties is required within the tyre development process. In this dissertation, methods for analysing the pressure-dependent tyre vibration and rolling radius behaviour on a tyre test rig are analysed. Cleat measurements on an external drum test rig have proven to be the most effective assessment methodology for the tyre vibration behaviour. Based on the measurement results, it is shown that the tyre vibration behaviour can be evaluated equally well both on the tyre test rig and in the driving test. On this basis, the test procedure on the tyre test rig is defined. By means of a concrete comparison of different tyres, the correlation of the results between driving test and test rig for the tyre vibration behaviour is demonstrated. An assessment methodology is developed that allows the tyre evaluation for indirect tyre pressure monitoring systems on the tyre test rig to be integrated into the tyre development process.
