Abstract:
1. A device for continuously determining wheel state variables of a tire of a vehicle, the device comprising: Wheel-side measuring devices each disposed in a respective wheel and configured for intermittently measuring physical variables of the wheel to provide measured values, the physical variables including a tire pressure and a length of a tire contact area; Vehicle-side measuring devices each mounted to the vehicle in a vicinity of a respective wheel and configured for continuously measuring physical variables of the wheel to provide measured values, the physical variables including the tire pressure and the length of the tire contact area; and A control and evaluation unit connected to receive the measured values from said wheel-side measuring devices and from said vehicle-side measuring devices; Said control and evaluation unit configured to perform a comparison by comparing the measured values provided by said vehicle-side measuring devices with the measured values provided by said wheel-side measuring devices or by comparing wheel state variables calculated from the measured values provided by said vehicle-side measuring devices with wheel state variables calculated from the measured values provided by said wheel-side measuring devices; and Said control and evaluation unit configured to correct the measured values provided by said vehicle-side measuring devices, or wheel state variables determined therefrom based on the comparison.
