INDICATING THE DIRECTION OF V2X


NXP, a semiconductor manufacturer that specialises in future technologies, looks to leave its tread marks visible in the automotive market with the rise of its V2X offerings. Huanyu Gu, senior product marketing manager on ADAS and V2X, discusses the company’s projected trajectory for V2X, particularly in light of their ongoing rollout of V2X solutions


F


or over ten years, NXP has operated as a key player in the automotive


sector; Vehicle-to-Everything (V2X) and Advanced Driver-Assistance Systems (ADAS) are consistently on the rise, so the company looks to highlight those sectors within its ongoing research and development, aiming to meet the 802.11p-based standard - Dedicated Short Range Communication (DSRC) - for wireless communication between vehicles. Despite the rise of the cellular alternative to DSRC, NXP sees the latter as an affirmative, proven technology, infrastructurally deployed around the world by a number of OEMs. The globular nature of its deployment is particularly important to NXP’s business strategy: the integration of NXP’s solutions in the DSRC sub-market demands a wide reach, as the network stretches continentally. For one example, Europe has seen its largest rollout of DSRC technology as a result of NXP’s collaboration with Volkswagen, with the car manufacturer’s new model – the Golf 8 – being made readily available. But the intentions are not and should not be continent specific: the ambition of NXP, as it should be for many automotive semiconductor specialists, is to inflate the V2X infrastructure so that communication remains seamless across Europe, the U.S., Asia, etc.


V2X AS A GLOBAL PROJECT It’s not just NXP that appears to prioritise this global integration – the continents, as mentioned, are keen to beckon in the dawn of DSRC automotive technology. Europe, as mentioned, underwent a noteworthy build-up of its V2X foundations. But in particular, country- specific cases accentuate these efforts. In Japan, Toyota is considered to be the first automotive OEM to push

V2X production – its DSRC solutions, operating at 760MHz – as far back as 2015: in the industrial timescale, this proves both a long-gestating desire and a committed development plan that has lasted up to this point. Furthermore, Singapore has an Electronic Road Pricing (ERP) system installed, which governs traffic through a usage-based taxation scheme via wireless, overhead monitoring: the size of the country is certainly small, but the result is suggestive of the possibilities for vehicular networking and communication. Finally, Austria has proposed its own composition of a V2X, DSRC infrastructure on its highways nationwide, starting this year with a projected conclusion by 2023. Regionally, the evidence is clear, exemplifying the demand for V2X and the desire to overcome the roadblocks that face its integration.


COLLABORATING WITH KEY ORGANISATIONS This demand stems back to a manifest motivation: a necessary improvement of road safety and a reduction in road penalties. Studying the numbers from the World Health Organisation (WHO), in 2016, 1.35 million casualties were caused by road traffic accidents. This marked a point from which V2X has grown, through some of the aforementioned incidences: communication between vehicles and an omnipresent network could mean the difference between a casual journey and a life or death scenario. Companies with mature technology must collaborate with stakeholders – carmakers, road operators and authorities, particularly the government with its jurisdiction over regulation – to prioritise and speed up the deployment of V2X technologies.

This collaboration originates at the relationship between the semiconductor manufacturer and the carmaker. NXP’s recent alliance with Volkswagen is one of many that continue to define the company’s investment in the automotive market, as the partnering enterprise sought NXP out, looking to utilise the manufacturer’s strengths to further the cause for V2X.


THE HYBRID MODEL This investment extends to a new model that NXP is advocating: the hybrid model. This looks to combine DSRC and traditional cellular technology, namely the 4G and 5G foundation that enables internet connectivity. The benefits of both come in their maturity – as mentioned, the more stabilised the technology, the quicker it can be arrayed. Considering the criticality of the application, this is essential. This is helped by DSRC’s low latency, as well as the cellular side driving comfort for the user, both of which, when combined, will reinforce the build of the vehicle and supplement the safety of the driver. NXP hopes that this could be the solution to the intended purpose of V2X technology.
