2022年11月3-4日，2022 C-V2XThe "Four Cross" (Suzhou) Pilot Application Demonstration Event was held in Suzhou, with 9 domestic and foreign vehicle enterprises, 22 terminal enterprises, 9 chip module enterprises, and 7 information security enterprises, totaling 23 fleets and 47 units participating in the demonstration.

Fibocom Auto Inc. Technology Co., Ltd. (hereinafter referred to as Fibocom Auto Inc.), as a vehicle terminal (V2X application) and module support enterprise, deeply participated in the demonstration of this four cross event and successfully completed the demonstration task.

The application scenarios demonstrated in this demonstration activity include two types: the first stage application scenario of C-V2X in the Internet of Vehicles and the second stage scenario of perception data sharing and collaborative vehicle lane changing. By demonstrating the perception of the second stage scenario, the practical value of large-scale promotion and application of C-V2X is further verified。

In this event, Fibocom Auto Inc.  showcased the first phase of V2V and V2I scenarios, including: forward collision warning, blind spot warning, emergency vehicle warning, intersection collision warning, vulnerable traffic participant warning, faulty vehicle warning, red light warning, green wave speed guidance, speed limit warning, interior signage warning, and other basic first phase application scenarios, as well as second phase application scenarios such as perception data sharing and collaborative vehicle lane changing.

Fibocom Auto Inc. V2X software products include three product package service forms: V2X protocol stack, V2X development kit, and V2X system service.

V2X protocol stack: optimized for HAL layers of different V2X chip manufacturers and in line with industry standards for mainstream technology in various layers of national standards. API interface including V2X message layer standard; Suitable for users who are familiar with the V2X system and have highly customized business logic (or even interaction logic) or vertical industry applications, can customize the development of application parts.

V2X development suite: based on POSIX standard API encapsulation, it provides flexible layered protocol software architecture. Implemented modeling and validation of application algorithms in multiple scenarios and environments. Encapsulate operational interfaces such as message interaction, multi-source data fusion, and configuration management as user APIs, and select application algorithms; Suitable for various V2X systems and product development, with customizable development of IPC parts.

V2X system services: providing V2X system services and IPC interfaces; The user (ECU) can directly obtain V2X (result) data from the IPC interface, focusing on the development of upper level HMI or integrated autonomous driving scenarios.

During the event, the self-developed V2X protocol stack and application software of Fibocom Auto Inc. fully verified the functionality and performance indicators of the terminal product based on the Fibocom Auto Inc. 5G+V2X (AN958T+AP915) module.
