Patent ID: 8855975

Claim:
A method for adjusting wheel diameter, comprising: acquiring a current wheel diameter distribution vector, wherein a current wheel diameter distribution vector represents a distribution of wheel diameters along at least one longitudinal direction of a vehicle; calculating similarity scores between the current wheel diameter distribution vector and known wheel diameter distribution vector clusters to determine a potential wear rate of the current wheel diameter distribution vector; calculating similarity scores between candidate target wheel diameter distribution vectors and the known wheel diameter distribution vector clusters to determine potential wear rates of the candidate target wheel diameter distribution vectors; and selecting a target wheel diameter distribution vector from the candidate target wheel diameter distribution vectors, such that the reduction of the potential wear rate achieved by switching the current wheel diameter distribution vector to the target wheel diameter distribution vector meets a predetermined condition, wherein selecting the target wheel diameter distribution vector from the candidate target wheel diameter distribution vectors comprises taking a reduction of potential wear rate achieved by switching the current wheel diameter distribution vector to a candidate target wheel diameter distribution vector as a switch benefit of the candidate target wheel diameter distribution vector, and taking a cost required for switching the current wheel diameter distribution vector to the candidate target wheel diameter distribution vector as a switch cost of the candidate target wheel diameter distribution vector, selecting the candidate target wheel diameter distribution vector for which the switch benefit is larger than the switch cost to a greatest extent as the target wheel diameter distribution vector.
