Publication number: 20250083640Abstract: Provided is a unified system between a fleet of heterogeneous vehicles and the vehicles' heterogeneous cloud services for delivering a unified user interface to remotely control the fleet of vehicles. The system performs several functions, including obtaining digital vehicle tokens for each vehicle, which allow commands to be triggered on the associated vehicle clouds to manage the vehicles. Sets of APIs corresponding to the vehicle clouds are obtained, and when a user sends a request for a specific vehicle, a digital user token is generated and mapped to the vehicle's digital vehicle token. Subsequently, when user commands for managing the vehicle are received, the system constructs vehicle commands using the APIs of the vehicle's cloud service. Finally, the digital vehicle token and the vehicle commands are transmitted to the corresponding vehicle cloud for executing the commands and managing the vehicle accordingly.Type: ApplicationFiled: September 9, 2023Publication date: March 13, 2025Inventor: Ruian Xu
