‘Completing the 24h of Le Mans in the innovative Garage 56 class, a world’s first!’

Racing a hybrid prototype vehicle, faster and more efficiently than a modern Formula 1 car. That’s the challenge for student race team InMotion. The team aims to compete in the Le Mans 24 hour race in a few years’ time. Johan van Uden is software engineer at ICT Group and is one of the founders of InMotion. In this blog he tells about InMotion’s ‘Road to Le Mans’ and about the vital contribution of ICT Group.

The 24h of Le Mans is the most demanding race in the world which pushes both drivers and cars to the limit. This race is all about endurance, which car can cover most laps in 24 hours. To achieve this, it is vital that the cars spend as little time stationary as possible. Therefore, the vehicle must be as reliable and energy-efficient as possible. It is not without reason Le Mans is often called the ‘Grand Prix of Endurance and Efficiency’.


Cars at Le Mans compete in different classes, including “Garage 56”. This is a special class for innovative cars with just one single spot on the grid every year. In a few years’ time we will compete in this class with a hybrid race car that we have developed ourselves entirely: the IM01. With the IM01, InMotion aims to be the first team to complete the full 24-hour race in this category. We will do this with a car that is both quicker and more efficient than any current Formula 1 car on the grid.

Reliable ECUs

We will build the IM01 with the experience acquired through the development of our test car: the KP&T IM/e. This in-house developed full-electric formula car will be used as a test platform for the IM01’s systems and technologies. Active aerodynamics (a real-time adjustable rear wing) and the electric drivetrain are currently being put to the test. The entire car is controlled by a few “boxes” containing advanced hard- and software: Electronic Control Units. These ECUs are the brains of the car.

The development of the ECUs for the KP&T IM/e is an enormous challenge. Firstly because there are ‘only’ three of them present in the car; the average passenger car has over a hundred ECU’s on-board to control every aspect of the vehicle. Why does the KP&T IM/e only feature three, one might ask himself? Reason: The fewer ECUs, the smaller the likelihood of technical problems during system integration. Extra challenging is the fact that these ECUs must continue to operate under very harsh conditions – 24 hours at full capacity. With battery packs that can supply 800 volts and 300 amperes the risk of fire or electrocution must be prevented regardless of any costs.

Motar toolbox vital

The software for the ECUs is normally coded manually based on mathematical control models. These calculations represented in a graphical way control the adjustment of electronic components such as traction control (for optimal grip) and active aerodynamics. At ICT we are able to develop the software for the ECUs using our Motar toolbox. Using this platform we can translate the graphical control models into software fully automatically – thus without the need for any manual coding or integration. This speeds up the development process of the vehicle, while reducing the likelihood of programming errors compared to hand-coding. All this increases the reliability of the ECUs. The ECU development has been a great test-case for both InMotion and ICT: Using Motar for the KP&T IM/e, we have demonstrated Motar’s added value in practice!

Testing with the KP&T IM/e

This year we will test the KP&T IM/e at Circuit Park Zandvoort. At the same time we will also have a go at beating the electric lap record. Our team, mainly students from Eindhoven University of Technology and Fontys Hogescholen, is currently preparing the car for these test sessions. We do this voluntarily as InMotion exists thanks to the support of a number of big sponsors, donations and technological partners. It’s wonderful to see how everyone is spending his or her spare evenings, nights and weekends on the project. I myself can be found at the Automotive Campus in Helmond every Wednesday evening.

At this moment the three ECUs are ready and are now being tested in preparation for the record attempt at Circuit Park Zandvoort. If this test is successful, we plan to make an attempt at beating the electric lap record around the Nürburgring Nordschleife later this year. After all this we should have gained sufficient knowledge and experience to start the production of the IM01. All this helps in realizing to our dream of competing at the 24 hours of Le Mans.
