This project is a proof of concept consisting of four functionalities, all of which are aimed at lowering DAF’s heavy-duty vehicles fuel consumption. In addition, the truck’s safety level, comfort level & road acceptance had to be maintained throughout the lifetime of the project. The proof of concept relies on the current ACC onboard forward radar. Firstly, an investigation took place, to determine the current system’s pitfalls and to highlight the opportunities for improvement. Moreover, using an internal database at DAF, a forecast of the functionalities impact on fuel consumption was determined based on data analysis. Furthermore, the functionalities were defined alongside the requirements and use cases. As a next step, the system was designed and developed with a preliminary architecture for simulation purposes. Later, an impact analysis took place with a corresponding HAZOP & HARA, to ensure the safe migration of the functionalities to the truck. Based on DAF’s preference, one functionality was migrated into the truck and operated successfully as per the proposed design and requirements.

The last hundred years witnessed a massive development of technology for road transportation of individuals and goods. These developments brought freedom to live at distance from work, quick responding emergency services and goods from all over the world available in our shops at competitive prices. Horse and donkey are replaced by cars and trucks with climate control, navigation and airbags. That these benefits are appreciated is demonstrated by the observation that 'peak car' is not reached yet: As indicated in figure 1.1, worldwide, the number of cars is still growing. Unfortunately, these widely appreciated benefits come at a price. Oil is the main motor of our transportation but the crude oil reserves decrease rapidly. As a result prices per barrel increase, and discussions arise to prioritize the use of oil to its application as raw material instead of as fuel.
