Steve Welch, Managing Editor of ‘future vehicle’ spoke to Mike Dempsey, Managing Director of Claytex, ahead of Cenex Expo 2024 to find out more about the company’s involvement in the Sim4CAMSens Innovate UK, Govenerment Funded, project and their in-house developed solution, Censeo – a ‘generalised simulation interface’.
Simulation and modelling are integral parts of the automated vehicle technology design, testing and validation process – but just how accurate are the models? Claytex, the UK’s leading AV simulation experts, is leading a collaborative project to ensure they’re as accurate as possible. Sim4CAMSens is funded by the Centre for Connected and Autonomous Vehicles to develop methods to quantify and simulate camera, radar and lidar sensor performance under all conditions. “The objective is to close the reality gap between simulation and real-world testing,” said Mike Dempsey, Managing Director at Claytex. “The project is about answering the question: How do we produce a sensor model that is ready and good enough for use in safety assurance in all the safety assurance processes?”
Sim4CAMSens promises to deliver a ‘step change in synthetic training data generation’ – proposing a new framework for sensor testing and simulation credibility. It will play a key role in ensuring AV safety assurance, providing real-world validation required by regulators and peace of mind for drivers, passengers and pedestrians. Sim4CAMSens brings together many of the UK’s leading automotive organisations, including the National Physical Laboratory (NPL), AESIN, Compound Semiconductor Applications (CSA) Catapult, WMG, Oxford RF, rFpro, Syselek and Claytex. When establishing the collaboration, Claytex and partners set themselves two key challenges, Dempsey said. “What does a sensor model that’s good enough for safety assurance actually look like? What effects does it include, and how do we validate the sensor model and prove that it is good enough?”

Simulation and modelling are core parts of Claytex’s business, and the company is recognised as the UK’s leading Dymola experts. This complex software package has incredible power, enabling engineers to test concepts and components. “With Dymola, we can build very complicated models. The tool itself is complex to use and is only ever really used by simulation engineers,” Dempsey said. This can prove to be a substantial barrier to adoption and innovation – so Claytex is developing a solution: Censeo. Censeo is described as a ‘generalised simulation interface,’ but what does that mean? “Censeo is a graphic user interface (frontend) that enables an end-user with limited or no Dymola experience to exercise one or more pre-compiled Dymola/Modelica-based simulation models,” Dempsey said. Censeo was primarily created to enable motorsport engineers to run multiple simulation tests and understand how minute adjustments to components like the suspension can affect – and hopefully improve – performance.
