A modernization of tools and processes is vital to develop more
innovative products that will integrate complex technologies and
comply with ever stricter standards. The upcoming Euro 6 and Euro
7, the European emission standards that define acceptable exhaust
emissions limits for new vehicles have increased the workload of
engine design and control design engineers.
They now have to integrate complex engine actuation and control
systems, required to optimize engine performance, while keeping
emissions at the lowest level possible. The growing number of
systems driven by controls, as well as the multiple interactions
between them, makes the engineering tasks more complex as engineers
need to take a higher number of degrees of freedom into account.
This has a direct impact on costs and times. In a quest of
rationalization, the deployment of system simulation for plant
modeling permits substantial gains in process efficiency all over
the development process. Using virtual engines and vehicles
significantly reduces the number of prototypes and the size of the
testing programs. Moreover, the application of physical plant
models for validation and calibration also leads to a faster
development and a higher level of reliability.
In this context, the paper presents how the LMS Imagine.Lab
AMESim® simulation platform can be effectively applied as a
supporting tool over the whole engine control development cycle.
Based on RENAULT's experiences, it illustrates the benefits of
the software deployment for the set-up of physical plant
models.
