Case Study: Scania achieves up to 11% fuel savings and faster development with MathWorks Model-Based Design

Scania Develops Fuel-Saving Driver Support System for Award-Winning Long-Haulage Trucks

Scania set out to develop a real‑time Driver Support system for its R‑Series long‑haul trucks to improve fuel economy, safety, and reduce emissions, but faced the challenge of deriving key metrics from more than 100 CAN‑bus inputs and validating algorithms early on hardware. To accelerate development and enable early ECU verification, Scania used MathWorks’ Model‑Based Design tools, including Simulink, Stateflow, MATLAB and Embedded Coder.

MathWorks’ tools were used to model and simulate subsystems (hill driving, braking, gear choice, anticipation), build a prototype user interface, run fault and scenario simulations, and generate embedded code for prototype and production ECUs now deployed on R‑Series trucks. The solution cut fuel use by up to 11% for drivers using the system, shortened development by about six months, achieved over 95% model coverage, and reduced regression‑testing from three hours of vehicle testing to 20‑minute simulations.
