Applying Model-Based Design to an On-Board Driver Support System for Economic Driving

Scania Driver Support is an on-board support system developed for heavy-duty trucks that went into production in the fall of 2009. It is designed to detect and analyze driving situations while driving. It identifies scenarios in which the driver's actions are especially important for the driving economy, and it gives advice on how to act just after a situation has been evaluated. Rating the driver’s behavior is also a part of the method to create a positive influence on the driving style. Each situation is awarded up to five stars, and an average score also shows the overall progress.
Four categories define the criteria with which the driver is evaluated:

1. Hill driving – Encourages the driver to adapt the speed to the terrain for better fuel economy.
2. Brake use – Rewards smooth braking and encourages the use of auxiliary brakes for nonurgent braking.
3. Anticipation – Focuses on the interplay between acceleration and braking and encourages a defensive driving style.
4. Choice of gears – Gives advice on using the correct gears for fuel economy and performance.

This presentation focuses on the development process for the on-board Scania Driver Support system.
