  • Publication number: 20250354895
    Abstract: Methods, apparatuses and computer program products for estimating tread wear of tires on wheels of a vehicle are provided. The tread wear is indicative of the difference between a starting tread depth and a current tread depth. The method comprises obtaining first second angular velocity sensor signals, indicative of angular velocities of at least one first wheel or axle of the vehicle, and of at least one second wheel or axle of the vehicle, respectively. It further comprises determining, based on the obtained angular velocity sensor signals, a tread wear difference value, which is indicative of the difference in tread wear between the tires at the first and second wheels or axles. It further comprises estimating, based on the determined tread wear difference value and based on a estimation relationship, a first tread wear estimate for the first wheel or axle.

  • Patent number: 12030348
    Abstract: The disclosure relates to systems, methods and computer program products for detecting tire pressure loss in tires of a vehicle. The system comprises a sensor, which is arranged at the vehicle remotely from the tires, mechanically coupled at least indirectly to a chassis of the 5 vehicle, and configured to detect a property indicative of tilting spatial movement of the chassis. The system further comprises a processing unit, which is communicatively coupled with the sensor, configured to receive sensor signals from the sensor, the sensor signals being indicative of tilting spatial movement of the chassis, and configured to detect a tire pressure based on the sensor signals. The processing unit is configured to detect a tire pressure loss responsive to the 10 sensor signals indicating a tilting spatial movement of the chassis towards the at least one tire.
