Fail safe device, a tire pressure measurement system, a vehicle, a method for monitoring, and a computer program
First Claim
1. A fail-safe device configured to monitor a first sensor of a tire pressure monitoring system, the fail-safe device comprising:
- a first input configured to receive a first signal from the first sensor, the first signal indicating a first physical quantity;
a second input configured to receive a second signal from a second sensor, the second signal indicating a second physical quantity; and
a control module configured to verify at least one of the first signal or the second signal, wherein the first signal is verified based on the second signal and based on a physical relation between the first physical quantity and the second physical quantity, and the second signal is verified based on the first signal and based on the physical relation between the first physical quantity and the second physical quantity,wherein the first signal indicates a tire pressure of a tire of a vehicle, and the second signal indicates at least one of a rotational speed of the tire and a contact patch size or footprint length of the tire.

Abstract
Embodiments provide a fail-safe device, a tire pressure measurement system, a vehicle, a tire, a method and a computer program for monitoring a first sensor of a tire pressure monitoring system. The fail-safe device includes a first input for a first signal from the first sensor. The first signal indicates a first physical quantity. The fail-safe device includes a second input for a second signal from a second sensor. The second signal indicates a second physical quantity. The fail-safe device further includes a control module to verify the first signal based on the second signal and a physical relation between the first and the second physical quantities.
