Connected mobility demands end-to-end secure & ultra-reliable high-speed, time-sensitive networking integration
01 April 2019
Automotive OEMs & Tier 1 suppliers are facing new challenges as they strive to design and build the next generation of intelligent vehicles. To support the future of connected mobility, they require ultra-reliable, high-speed connectivity solutions, with seamless end-to-end network integration across hardware, software & services.

In response to intense industry demand, electronic solutions provider, Molex offers a complete in-vehicle networking ecosystem that enables the automotive industry to meet these requirements. Joe Stenger, Global Product Manager – In-vehicle Networking, Gateway & Switch Solutions at Molex, explores the connected mobility megatrend, as it continues to redefine not only cars, but also an entire intelligently interconnected urban transportation infrastructure. Alex Bormuth, Director of Business Development (Germany), Connected Mobility Solutions also outlines how Molex’s 10Gbps high-speed, time-sensitive automotive Ethernet network platform can fully integrate mission critical applications to deliver signal integrity, network traffic prioritisation, system scalability and security – all of which are essential to optimal autonomous vehicle performance.
A paradigm shift is coming
The automotive sector stands on the brink of a revolution that will transform vehicles themselves, our relationship with them and how they interact with the environment around them. As with other sectors, the impact of digitalisation and new business models are being felt in the automotive landscape. According to a report by Citi (Car of the Future v4.0: The Race for the Future of Networked Mobility, January 2019, Citi Global Perspectives & Solutions), by the year 2030, the auto industry will be characterised by four types of verticals: Robotaxis (mobility on demand); AV subscriptions (driverless capable cars); combination of Robotaxis/AV subscriptions; and traditional ownership.
Connected mobility encompasses a range of applications and technologies that represent the future of our intelligently interconnected urban transportation infrastructure, including the advanced driver assistance systems (ADAS), connected infrastructure and V2X (vehicle-to-everything) technologies that will enable automated driving (AD) vehicles. But it will rely on more capable high-speed, ultra-reliable, time-sensitive networks than are currently in general use, both in-vehicle and beyond.
There is a fairly universal agreement across many market studies that the value of the global autonomous vehicle market will grow substantially during the next decade. However, when it comes to the car of the future, the Citi report states that there has got to be greater stakeholder alignment. It goes on to say that when thinking about innovations such as AI, connectivity, electrification and big data, there is perhaps no more obvious use than the Car of Today. The age of mass-market personal cars solved many of yesterday’s mobility problems, but also created new ones, such as congestion, pollution and underutilised urban infrastructure. Vehicle safety, while vastly improved, remains a substantial societal and economic problem, which unfortunately is not getting any easier in the age of distracted driving.
The Car of the Future then, as cited in the report, combines advancements in AI, connectivity, computing power and electrification – and promises not only to address many of these problems, but also to potentially transform personal mobility as we know it. The immediate question that arises is: “who pays for it all?” The short answer is that it can pay for itself – and this creates a historic alignment of stakeholder interests.
The Citi report postulates what kind of changes are coming and how they might affect traditional vehicles, stating that the greater stakeholder alignment can be boiled down as follows:
• Societal: The unfortunate reality is there are over 1.3 million annual road fatalities. Rising global auto penetration has led to greater road congestion, tailpipe pollution, and underutilised infrastructure. There is also an increasing need to serve an aging population, those with disabilities, and to ensure better access to personal mobility across varying income levels. Ultimately, the human and economic toll of today’s vehicle transportation system serves as the backbone of this alignment of interests.
• New revenue streams: Vehicle data monetisation and time-spent-in-car, as vehicles become more connected with advanced electrical architectures enabling over-the-air (OTA) updating, are new revenue streams being introduced. Those OTA updates also continuously leverage data and learning iterations to improve safety throughout a vehicle’s life.
• New addressable markets: Urban autonomous Robotaxi networks that can provide low-cost, safe and convenient mobility access, while offering what we regard as lucrative financial returns to industry leaders could open new markets. Robotaxis could of course also help address urban congestion, pollution, and infrastructure through lower vehicle ownership in major cities. There are also new concepts like AV subscription networks, which could yield a huge transfer of wealth into new mobility ecosystems, combining the best of traditional ownership with the benefits of shared mobility. That transfer of wealth would spur faster adoption (because of greater affordability), thereby more rapidly transforming the vehicle installed-base into a safer fleet, and eventually, even a smaller-sized fleet. This, it is believed, can be done without compromising a consumer’s desire to have an instantaneously accessible vehicle 24/7.
The need for speed
Electronic and computing technologies have transformed almost every aspect of our lives in a single generation, with automotive experiencing greater change than many industries. The amount of electronics, software and computing power in modern vehicles has revolutionised both how they work and how we view them – more like rolling computers than mechanical devices. The number of electronic control units (ECUs) in vehicles has multiplied from just a few up to a hundred (or even more in high-end vehicles), controlling everything from engine management, ignition timing and fuel injection to anti-lock braking, traction control and, more recently, automated braking and lane or safe distance-keeping for adaptive cruise control (SAE levels 1 and 2 – driver assistance and partial automation). At the same time, there has been an increase in the numbers of interior and exterior sensors, advanced telematics and infotainment systems, plus the multiple electronic control units and distributed automotive networks (usually CAN, LIN, FlexRay and Ethernet) to manage all this data and technology.
And as vehicles become more connected and autonomous, this trend is accelerating exponentially, with massive amounts of computing power, bandwidth and speed required to process the huge amounts of data generated by a fusion of sensors (including cameras, RADAR, LiDAR and ultrasonic) in real-time to make split-second decisions that mimic safe and human-like driving. This means they need a universally standard, reliable and extremely fast end-to-end network architecture – any kind of delay or latency in transmitting vital information within autonomous vehicles could potentially be lethal for passengers, other road users or pedestrians.
Estimates vary, but vehicles may generate and consume up to 40 terabytes of data per day – meaning 5G cellular connectivity is critical, as it promises to connect everything around us to a data network that delivers the speed, responsiveness and reach to unlock the full capabilities of autonomous vehicles. Meanwhile, semiconductor companies are developing breakthrough microchips that will enable high bandwidth data speed at 10 Gbps+ with innovative and multi-zone vehicle architectures, turning cars from rolling computers into data centres on wheels, enabling autonomous vehicles to make complex, in-application real-time decisions.
As existing automotive networks prove lacking in the face of evolving requirements, Ethernet has emerged as the main automotive data protocol for high-speed data transmission, driven by increased data rates and redundancy requirements for autonomous driving, safety and security concerns in connected environments, and the need for standardised, inter-industry protocols. Ethernet offers a mature, stable and proven technology, capable of delivering high speeds and security. However, automotive Ethernet architectures are subjected to a harsher environment than many traditional Ethernet deployments, and so need to be more robust – having to cope with extremes of temperature, humidity, water, vibration and shock, and moreover with high levels of electromagnetic interference (EMI).
