Claim 9:
10. The system for predicting health of at least one tire of a vehicle comprising:
an input/output interface for receiving one or more vehicle design data, temperature of the tire, information on vehicle longitudinal and translational forces, set of historical operational data of the tire from at least one predefined data source, environmental data and road type and condition;
one or more hardware processors;
at least one memory in communication with the one or more hardware processors, wherein the one or more hardware processors are configured to execute programmed instructions stored in the memory, to:
identify a stationary digital regime and a non-stationary digital regime of the at least one tire of the vehicle, wherein the stationary digital regime is identified for a stationary vehicle in one or more predefined positions;
calculate a tread quality index in terms of a tread size and a tread height against a predefined threshold value of the tread quality of the at least one tire, wherein the tread quality index is calculated based on a set of operational data of the at least one tire;
calculate a pressure value of the at least one tire of the stationary based on a vehicle load, material characteristics and an ambient temperature of the at least one tire, wherein the calculated pressure value is a cool down pressure value provides a baseline pressure value for training a data-driven model;
capture rate of generation of at least one flat spot of the at least one tire based on the calculated tread quality index, the calculated pressure value, the ambient temperature, the vehicle load, and one or more road surfaces;
calculate a surface index of the tire with respect to a predefined ideal surface for the at least one tire, wherein the vehicle operates on the one or more road surfaces for a predefined time under one or more specific environmental conditions;
determine operating load index of the at least one tire with respect to a predefined ideal load on the at least one tire, wherein the operating load index includes one or more of operation parameters, wherein the one or more of operation parameters comprising a braking force, and a tractive effort;
capture one or more vehicle operation parameters in the form of vehicle operation index;
calculate a tire inflation index based on a pressure saturation value of the at least one tire, the ambient temperature, an initial temperature of the tire, a vehicle speed, an initial pressure value within tire, the calculated surface index, the determined operating load index, and the vehicle operation index;
estimate a variation in the health index of the tire based on the captured flat spot of the tire, the calculated tread quality index, the set of historical operational data of the tire, and the calculated pressure value of the at least one tire of the stationary vehicle; and
recommend an optimal usage pattern based on the estimated variation in the health index of the tire of the running vehicle under different environmental conditions and at different vehicle speeds as one of a plurality of operating or non-operating constraints.
