Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for receiving and integrating vehicle data for a fleet of different types of rental vehicles from across different databases to generate vehicle-data summaries for such rental vehicles—as well as for surfacing tools for dispatch, service, and other vehicle managing functions. In some cases, the disclosed systems further identifies and integrates service data from vehicle service centers associated with the rental vehicles into a central database and into the vehicle-data summaries. Such a fleet of rental vehicles can include personal-rental vehicles, provider-rental vehicles—such as express-provider-rental vehicles and flexible-provider-rental vehicles—as well as third-party-rental vehicles.
