This post looks at how the inverse of a function can be provided by using the inverse () annotation. Also, an example is provided where the inverse function is used. Why supply an inverse to a function? During translation, symbolic manipulation will reorder the equations into a form that...

There are many ways to simulate a vehicle following a driving line, but the most realistic results are gained using a driver model. However, a driver model conventionally uses a line to follow, either created from scratch or using reference data. The difficulty is creating a realistic driving line...
Founded in 2015 at Nagoya University in Japan, Autoware is an open-source software for autonomous vehicles and embedded systems providing a complete set of self-driving modules, including localization, detection, prediction, planning, and control. It is a framework built on top of ROS for autonomous vehicle development, testing and validation...
Previously on the Claytex Tech blog, we have deconstructed the Simulation log, explaining what each of the quantities identified within it relates to. But what about the Translation log? What is it? What do the quantities described there actually relate to? And more importantly, how can I use the...
We have just completed another Bus modelling demo using the VeSyMA suite of libraries that we develop at Claytex. This time the objectives were related to energy management of the overall vehicle and understanding the losses within the powertrain and driveline. This gave the base to studies that involved...
The validation and verification of autonomous systems poses a range of complex challenges. Whilst physical testing continues to be useful, the proliferation of conditions and variables means that new virtual methods are needed. There is an urgent demand for a comprehensive understanding of ADAS, connected & autonomous vehicles behaviours...
Create reliable testing for ADAS and AV by configuring the simulation solver and segmenting the vehicle control cycle
Overview Claytex have released the UAV Dynamics library that allows the user to build and analyse the flight dynamics of a UAV in a quick and intuitive modular approach. Contents Architecture examples have been included as well as controllers and propulsion devices. The example included is that of a...
VeSyMA, the Vehicle Systems Modelling and Analysis suite from Claytex, has a new addition in 2020: VeSyMA – Motorbike! Overview: VeSyMA – Motorbike was introduced to satisfy the multi domain simulation needs of the motorcycle industry. The current capabilities range from energy consumption to driveability and performance analysis and...
When a model is translated, warnings may be present in the translation log. One of the frequently occurring warnings is the Redeclaration requires a subtype warning, this post looks at how to fix this issue. Why does this warning occur? The Redeclaration requires a subtype warning occurs when a...
