Abstract

A vehicle management system includes a first module having a plurality of functions. The vehicle management system also includes a second module and a system bus. At least the first module and the second module communicate on the system bus. The vehicle management system further includes an identifier based on one of a plurality of vehicle types. When a first vehicle type is identified, a first set of the plurality of functions is utilized based on the identifier associated with the first vehicle type. When a second vehicle type is identified, a second set of the plurality of functions is utilized based on the identifier associated with the second vehicle type.
