Collaboration and cooperation on our roads

Connected Autonomous Vehicles.

Communication between vehicles and Smart City infrastructure is fundamental to the CAV revolution.

Around the world, governments are recognising that autonomy requires cooperation — CAVs will need to communicate with each other and with Smart City infrastructure.

In the US, the National Highway Traffic Safety Administration believes the advancement of vehicle automation depends on fusion of connectivity and onboard technologies. The European Commission Declaration of Amsterdam calls for the convergence of investments and regulatory frameworks across the EU to enable deployment of interoperable connected and automated driving by 2019.

Cohda Wireless is a global leader in the mobile outdoor communications that will realise the full potential of Connected Autonomous Vehicles. We have already solved critical issues such as CAV localisation, sensor fidelity and system cost. Our next generation of CAV application layer software is giving car manufacturers the keys to advanced CAV projects, including:

  • Improved driving environment monitoring using radar;
  • Optimised traffic efficiency through cooperative cruise control;
  • Accurate positioning to improve driving tasks;
  • Enhanced performance data collection.

CAV Apps

Cohda Wireless has overcome critical CAV obstacles, including CAV localisation, sensor fidelity and system cost. Our CAV software also ensures security, privacy and functional safety across all applications.

Our next generation of CAV application layer software solves further technical issues, allowing car manufacturers to deploy tomorrow’s CAV projects today.

Accurate real-time positioning is critical to CAVs, but GNSS can be unreliable in city landscapes that frequently obscure a sky view in urban canyons, tunnels and undercover car parks.

Cohda has developed a software solution to position vehicles with sub-metre accuracy in GNSS black spots, using RSUs and/or Wi-Fi access points.

Cohda’s V2X-Radar system overcomes the limitations of current sensors that hamper a CAV’s ability to identify and assess hazards, especially in rain, snow and fog, and where there is no line-of-sight.

V2X-Radar transforms a V2X system into a 360° radar system with no additional hardware. It uses standard V2X transmissions from multiple sources, such as other equipped vehicles and RSUs, to illuminate the world and distinguish between static and dynamic objects, identifying their position, velocity and direction of movement.

As well as helping CAVs identify and assess potential hazards, V2X-Radar can be used in plausibility checking and positioning.

Cohda’s fifth-generation On-Board Unit (OBU), the MK5 is a small, low-cost, rugged module that can be retrofitted to vehicles for aftermarket deployment or field trials, and can also serve as a design reference for automotive production.

The MK5 exchanges data at high speeds over extended distances, providing class-leading reaction times to potential hazards and safety-critical scenarios. In challenging outdoor conditions where no line-of-sight is available, its radio performance is unmatched.

Built with the same chipset as the MK5 OBU, the MK5 RoadSide Unit (RSU) is a rugged outdoor unit with integrated dual antennas, housed in a NEMA 4-standard weatherproof enclosure.

Designed for Smart City deployments, the MK5 RSU offers exceptional range and coverage, and a single, inexpensive, self-contained unit can cover all approaches to an intersection. It’s available in mains and Power over Ethernet (PoE) variants.
