The widespread application of automotive electronic systems and in-vehicle network technology is driving the rapid development of standardized automotive diagnostic technology. ABUP-RVDS combines automotive diagnostic technology, wireless communication technology and an in-vehicle network platform, giving the opportunity to combine the car, the owner, the diagnostic expert and the diagnostic management platform. The in-vehicle network-based diagnostic technology acquires vehicle information and sends it to the diagnostic platform, enabling real-time interaction and information sharing between inside and outside the vehicle. Diagnostic experts can access and analyse vehicle data, perform OTA upgrades and troubleshoot remotely without being physically present.
