New ESC Example

Governments throughout the world have instituted regulations mandating that vehicles be equipped with ESC, or requiring them to meet performance standards that are designed to be unachievable by vehicles without ESC. For example the USA standard FMVSS 126 and the ECE regulation 13H both use a test process called “sine with dwell” to confirm that the vehicle being tested has a functioning ESC.

The vehicle models in CarSim do not have built-in ESC. Detailed ESC models are typically added with an external simulation environment such as Simulink or LabVIEW. In some cases, the ESC is defined 100% with software and can be run with the core Windows-based CarSim software; in other cases, CarSim RT is used to run hardware in the loop (HIL) with ESC hardware.

Another method for adding a controller to a VS math model is through VS commands. In fact, a simple ESC defined with VS commands has been provided in CarSim since version 8, in order to illustrate a basic ESC function in the FMVSS 126 / ECE R13H examples.

The example ESC has recently been updated, and a technical memo was written to document the control logic and some of the VS commands concepts that are used. The ESC that has been installed in CarSim will be replaced in future versions of the software with the controller described in this memo.

On April 23, 2012, Mechanical Simulation hosted a group of visitors in town for the SAE World Congress to tour our office. Visitors had an opportunity to test and experience our driving simulators and meet with our staff. The event was a great success!
