The MathWorks has released its Model-Based Calibration Toolbox for the automotive industry.
The MathWorks has released its Model-Based Calibration Toolbox for the automotive industry.
The toolbox offers the latest model-based design features and enables engineers to identify accurate performance settings for powertrain systems.
It also allows them to maximise valuable design resources by developing powertrain systems using data-modelling methods in conjunction with Design of Experiments methodology.
"By building on the high-performance technical environment of Matlab and offering the simulation capabilities of Simulink, the Model-Based Calibration Toolbox allows engineers to systematically find optimal calibrations for complex powertrain systems", said Chris Hayhurst, principal engineer at The MathWorks.
"The Toolbox minimises test runs, allows teams to easily share data and generate calibration tables from fitted models.
This all adds up to reduced testing time, increased productivity and improved performance; crucial elements in the highly competitive automotive industry".
The Model-Based Calibration Toolbox guides users through the three basic steps of powertrain calibration.
The first step is to plan the physical testing to be completed on the dynamometer (or with a virtual engine plant model).
After the dynamometer tests are completed, the second step is to use the measured data to produce a set of response models that accurately reflect the engine behaviour.
The last step is to make use of these models to calibrate the powertrain system.
"We are only beginning to explore the capabilities of this toolbox but already we are finding significant savings in testing time", said Stuart Briscoe, lead calibration engineer of Prodrive, the motor sport and automotive technology group.
"There are many spin-off benefits from the Model-Based Calibration Toolbox including the re-use of existing data and the visualisation of calibration interactions.
Future benefits may include quantifying late engine hardware changes and their impact on the calibration and engine program".
"It has been very easy to combine our industry knowledge and experience with The MathWorks' skills and expertise in order to develop new approaches and processes for powertrain EMS development", Briscoe added.
"We are looking forward to continuing this partnership".
