Advanced simulation tools supporting HumanDrive and wider CAV roll out

  • Software packages developed to deliver a highly accurate digital twin of the real world, and to merge and manage multiple simulation platforms
  • Both simulation tools being used by HumanDrive project partners to achieve 230-mile autonomous journey later this year, and to support wider CAV roll out

Visualisation experts at the Connected Places Catapult (CPC) have developed a unique and innovative simulation tool to support the HumanDrive project and wider Connected and Autonomous Vehicle (CAV) development, enabling project partners and developers to visualise trials data in a highly accurate digital twin of the real world.

Built following a series of real-world and simulated trials carried out by project partners Cranfield University and the University of Leeds, the tool is helping the HumanDrive team to better understand how humans drive. Uniquely, it enables developers to interrogate and filter data – collected from real-world and simulation trials, human factor observations and monitoring of drivers, and on-board sensor equipment such as lidar – with a specific question in mind.

Martin Pett, Principal Technologist at the CPC, said: “We needed to create a digital twin of the trial environment in a user-friendly format so that project partners can replay and filter reams of data for deeper analysis. For example, how the trial participant positioned themselves when they passed a cyclist, their acceleration or braking profiles, how they held the steering wheel, or how weather conditions affected their speed.”

“The tool is built on the Unity platform – a cross-platform, real-time engine for simulation construction commonly used by game developers – and allows you to replay the entire trial virtually, whilst seeing all the data that was generated from multiple participants, all in one place and time synchronised. It really is a fantastic tool that can be used by individuals who may not have modelling experience.”

Also developed by the CPC is a light-weight software infrastructure called ‘simulation to simulation’ (s2s) that helps integrate simulators and simulations. Simulation has the potential to allow CAV developers to explore thousands of design iterations in a rapid and cost-effective manner, adapting real-world scenarios as required (from changing weather conditions to manipulating physical environment and introducing hazards) with minimal input. s2s provides a means by which simulations may be joined together to support this goal.

Ecaterina McCormick, Senior Technologist at the CPC, said: “This free piece of software – which is unique to the transport sector – allows users to bring together and effectively manage different simulation packages in a controllable, simple way. Different simulation packages have their strengths and weaknesses – s2s allows you to get the best out of them all, and we’ve made it free for people to use. Already there is great interest from world-leading institutions.”

HumanDrive is being developed by a world-leading consortium and will culminate in a 200-mile, live-traffic journey that is both driverless and human-like. The HumanDrive consortium consists of Nissan’s European Technical Centre, Hitachi, HORIBA MIRA, Atkins Ltd., Aimsun Ltd., SBD Automotive, University of Leeds, Highways England, Cranfield University and the Connected Places Catapult.

CAV Cyber Security Framework

Vehicles have evolved to become increasingly connected with in-vehicle devices and external systems and infrastructure. Connected and Autonomous Vehicles (CAVs) will soon begin to appear on our roads whilst at the same time, cyber attacks across all sectors are increasing in regularity and sophistication. To provide assurance to the public that the security risks associated with CAV technology are being appropriately managed, SNC Lavalin’s Atkins business has developed a comprehensive CAV Cyber Security Framework (CCSF).

 

The CCSF is based on the five functions (Identify, Protect, Detect, Respond and Recover) of the globally recognised National Institute of Standards and Technology (NIST) Cyber Security Framework. The five functions of the CCSF are supplemented by a combination of industry standards and best practice to create a set of cyber security outcomes and objectives. This framework is being used by consortium partners to aid the delivery of a secure CAV ecosystem for HumanDrive.

BBC’s Law in Action experience HumanDrive at Cranfield University

Cranfield University’s Multi-User Environment for Autonomous Vehicle Innovation (MUEAVI) provided the location for part of a recent Law in Action recording focused on the legal implications of connected and autonomous vehicles (CAV) on UK roads.

 

Neil Fulton, Connected and Autonomous Transport Programme Director from the Transport Systems Catapult, was interviewed about the HumanDrive project, which is using the Cranfield MUEAVI autonomous vehicle test site to put the HumanDrive vehicles through their paces by simulating a number of scenarios and monitoring the cars’ reactions.

 

MUEAVI is a new £9 million open research facility, comprising a mile of ‘shared surface’ fully functioning roadway and pedestrian access through the centre of the campus, to support the development of autonomous transport vehicles and related systems.
