Austrian-based manufacturer of engine, transmission, emission testing products and supplier to BMW, Porsche, Mercedes, and other vehicle manufacturers.

Coast down test is one of the most frequent tests in the automotive industry. Testing is performed to estimate the vehicle movement resistances: aerodynamic drag, brake drag, bearing and transmission drag - parasitic drags tend to act in the opposite direction of movement.
The car is driven up till a certain speed, then the gear is put to neutral and the vehicle coasts till it stops, simultaneously recording the speed profile, traveled distance and other parameters.
One of the critical requirements of the coast down testing is compliance with the proper speed limit. The customer needed a special software tool that helps the driver to maintain the prescribed speed profile while operating the vehicle on the test bed.

The customer wanted to get a cross-platform application that may work on different desktop and mobile devices. We chose HTML5 because this technology meets all customer requirements, and our engineers have extensive experience in developing high-performance web applications.
The developed solution allows the driver to display the data needed to conduct the coast down testing (speed profile, force, power) in real time with a high refresh rate and, save them for the later analysis.


• Display of current measurements of the tested vehicle;
• Storage of necessary records for historical analysis;
• Recording of any deviation from the outlined procedures and the reason for the deviation.

Technology stack: HTML5/CSS, C/C++, JavaScript.

Applied Systems’ solution has become an essential component of the customer`s automotive test system. Our application provides the driver and test operators with easy access to specific data required for the coast down testing.
