Patent ID: 8577643

Claim:
An apparatus for ascertaining a relative position of a first tire and a second tire in a multiple tire, the apparatus comprising: at least one processor and a non-transitory computer readable medium having a set of computer-readable instructions stored thereon, which when executed by said at least one processor, causes said at least one processor to implement a plurality of units including: a reception unit configured for receiving a first sensor signal indicating a contact area length of a first tire in a multiple tire from a first electromechanical transducer associated with the first tire, said reception unit configured for receiving a second sensor signal indicating a contact area length of a second tire in the multiple tire from a second electromechanical transducer associated with the second tire; a contact area characteristic ascertainment unit ascertaining a contact area length characteristic of the first tire based on the first sensor signal and ascertaining a contact area length characteristic of the second tire based on the second sensor signal; and a position finding unit ascertaining a position of the first tire relative to the second tire in the multiple tire by evaluating the contact length characteristic of the first tire and the contact area length characteristic of the second tire during cornering.
