Method, component, tire-mounted TPMS module, TPMS system, and machine readable storage or computer program for determining time information of at least one contact patch event of a rolling tire, method for locating a tire
First Claim
1. A method for determining a time information of at least one contact patch event of a rolling tire, comprising:
- obtaining information indicative of a rotational rate of the tire;
obtaining a sequence of samples indicative of at least an acceleration component during at least one rotation of the tire; and
determining a position of at least one reference sample in the sequence, wherein the position of the at least one reference sample is indicative of the time information of the contact patch event of the rolling tire.

Abstract
Examples provide a method, a component, a tire-mounted TPMS module, a TPMS system and a machine readable storage or computer program for determining time information of at least one contact patch event of a rolling tire and a method for locating a tire. A method for determining time information of at least one contact patch event of a rolling tire, includes obtaining information indicative of a rotational rate of the tire; obtaining a sequence of samples indicative of at least an acceleration component during at least one rotation of the tire; and determining a position of at least one reference sample in the sequence, wherein the position of the at least one reference sample is indicative of the time information of the contact patch event of the rolling tire.
