At China Euro Vehicle Technology (CEVT), new development techniques are being created to bring new technologies into passenger vehicles, and ensure successful integration of the many systems present in modern designs.
The demand for innovation is universal across industries, as new products are required to meet higher performance standards without slowing the overall time to market. This reality is perhaps most apparent in the automotive industry, where a wide range of technologies must come together seamlessly if a new product is to be successful. At China Euro Vehicle Technology (CEVT), new development techniques are being created to bring new technologies into passenger vehicles, and ensure successful integration of the many systems present in modern designs.
The team at CEVT is aiming to create a powerful simulation platform that can validate a wide range of design components, from software controllers to individual hardware subsystems, in what is known as "in-the-loop" simulations. For these kinds of simulations, the system-level models are created not only to be highly accurate, but they must be capable of very efficient computation for real-time usage on test platforms. They chose MapleSim for its ability to create efficient royalty-free code that can run in real-time.
In order to avoid the slowdowns typically involved with taking on a new modeling tool, the Chalmers research team opted for customized training services provided by Maplesoft Engineering Solutions. During a three-day training program, modeling experts from Maplesoft worked directly with the research team, helping them become proficient with MapleSim. The team quickly worked through the basics of model creation, before moving on to training related to their specific project needs, including code generation, exporting models to the Functional Mock-up Interface (FMI) standard, and creating custom components to account for their specific designs. "Its very easy to get started with MapleSim," noted Mr. Palander, as he observed his team moving quickly through their design-specific modeling needs.
By working with Maplesofts modeling experts, the teams at Chalmers and CEVT were able to easily and efficiently develop workable processes for integrating MapleSim with their own tools, such as their simulation platform, CarMaker. They now use MapleSim to create vehicle models and export them into Functional Mock-up Units (FMUs), which then connect into the rest of their toolchain. The training also provided the engineers and researchers with MapleSim model optimization techniques so they could make quick iterations on design concepts before moving their testing to their in-the-loop simulation platforms.
The approach taken by CEVT in evaluating MapleSim and training as a team in system-level modeling is a sign of their larger commitment to new, innovative approaches in vehicle design. By looking to integrate powerful system-level modeling tools like MapleSim, CEVT is maintaining its position as a leader in virtual engineering techniques. CEVT also ensured they stayed competitive by using Maplesofts Engineering Solutions to evaluate their new software as quick as possible. With help from MapleSim, Mr. Palander is confident that CEVTs system-level modeling project is proceeding in the right direction: "We will succeed in this, I am absolutely sure."
