Defining Digital Quadruplets in the Cyber-Physical-Social Space for Parallel Driving
This work addresses the challenge of integrating virtual and real components in autonomous driving systems, but it appears incremental as it builds on existing ACP methods without introducing major new breakthroughs.
The paper tackles the problem of synthesizing vehicle intelligence and transport automation by defining digital quadruplets (descriptive, predictive, prescriptive, and real vehicles) within the cyber-physical-social space for parallel driving, aiming to enhance safety, efficiency, and synergy in connected automated driving.
Parallel driving is a novel framework to synthesize vehicle intelligence and transport automation. This article aims to define digital quadruplets in parallel driving. In the cyber-physical-social systems (CPSS), based on the ACP method, the names of the digital quadruplets are first given, which are descriptive, predictive, prescriptive and real vehicles. The objectives of the three virtual digital vehicles are interacting, guiding, simulating and improving with the real vehicles. Then, the three virtual components of the digital quadruplets are introduced in detail and their applications are also illustrated. Finally, the real vehicles in the parallel driving system and the research process of the digital quadruplets are depicted. The presented digital quadruplets in parallel driving are expected to make the future connected automated driving safety, efficiently and synergistically.
