AMTs combine the fuel efficiency, performance and control of manual systems with the convenience of automatics, an especially handy feature in stop-and-go traffic.

However, these complex mechatronics systems are difficult to design because their performance depends on the operation of three different subsystems all working together in perfect synchronization: an electromechanical actuator that shifts the gears, electronic sensors that monitor vehicle status and software embedded in the transmission control unit (TCU), the brains that control the powertrain.

Software development and calibration present particularly troublesome bottlenecks since these tasks typically require extensive trial-and-error physical testing cycles that cannot be performed until hardware prototypes are built.

Considerable time is spent troubleshooting problems near the end of the design rather than refining TCU control strategies.

To meet looming vehicle launch deadlines, engineering teams must often settle for an overall design that barely meets application requirements rather than one that optimally balances mechanical, electronics and software performance.

Engineers drag, drop and interconnect simple icons to graphically create the model displayed on the screen with a working sketch showing the relationship between all the various elements to predict the behavior of entire AMT system.

By using the multidomain simulation approach based on Simcenter Amesim, we can see early in development how all the various parts of the complex AMT system will operate together: mechanics, electronics and control software, says Edouard Ngre, senior design engineer in the Renault Powertrain Control Engineering Division.

With this understanding of the complete mechatronics system, we can readily optimize the entire design up-front in development and avoid many late-stage problems and delays.

Renault most recently used the method to develop a new actuator for one of its existing AMT models, redefine the existing TCU control strategy and evaluate the entire AMT performance.

Next, parameters from design drawings and technical data from engineering specifications were added to plot overall performance curves, define basic control commands and determine the overall response of the complete mechatronics system.

In these conceptual phases, engineers explored the behavior of various alternative mechatronics configurations including actuator designs to provide for smooth gear shifting until the best powertrain performance was achieved.

Simcenter Amesim was used to simulate the powertrain hardware in this software-in-the-loop (SiL) approach, essentially providing a virtual engine and transmission as stand-ins while the actual hardware was still in development.

In this way, engineers finetuned the TCU software to achieve optimal powertrain performance according to fuel efficiency, dynamic response and other operational factors.

Refining the performance of the mechatronics system early in development avoids problems that take considerable time to resolve later in the development cycle.

Moreover, using SiL and HiL approaches to develop, calibrate and validate TCU software in parallel with hardware development and fabrication constitutes an immense time savings.

The models developed and lessons learned with this project will be used as a basis for further time and development savings in the future.

With this process, Renault will be launching more new vehicle models with AMTs months sooner than would otherwise be possible.
