A Distributed Vehicle-Infrastructure Cooperation System Based on OpenHarmony

The rapid advancement of transportation has sparked interest in Vehicle-Infrastructure Cooperation System (VICS), a novel transportation system that emphasizes the coordination of transportation facilities. However, this system consists of multiple heterogeneous devices, including roadside sensors, autonomous vehicles, traffic lights, cellphones, etc. The disparate communication capabilities among these devices result in poor development efficiency and compatibility, necessitating the establishment of a unified and standardized communication mechanism. Distributed operating systems, which operate across multiple devices and manage inter-device communication, offer a promising solution to this challenge. OpenHarmony, an emerging distributed operating system, has been applied in various interconnection scenarios to successfully resolve the communication and development complexities, but not has limited use cases in VICS. Therefore, this paper addresses this gap by constructing a miniaturized hardware platform of VICS and utilize OpenHarmony as the universal operating system to develop and deploy self-driving algorithms. The main target is to explore and demonstrate the capability of OpenHarmony in the application area of VICS. The miniatured hardware consists roadside perception systems and self-driving vehicles at smaller scale to simulate the real-world scenario. Initially, the paper proposes a system framework based on OpenHarmony, leverages the communication capabilities of OpenHarmony’s distributed soft bus to enable data exchange between vehicles and roadside perception systems, and designs a quality measurement index for evaluating multi-perception results. Subsequently, the roadside perception system with vehicle localization algorithm and the self-driving vehicle with planning and control algorithms are developed. In the end, this paper utilizes this comprehensive VICS system to explore the capability of OpenHarmony and discuss the potential of OpenHarmony in this area.
