This project carried out the design and the implementation of a roll stability system for a simulated heavy vehicle. The purpose of the system is to prevent rollover. The making of the system consists of three parts; calculating the roll angle, calculating a rollover index and constructing the control system.
Experiment
The benefits of the system were measured by conducting a study in which test persons drove the simulator truck both with the stability system switched on and switched off. The scenario in the study was carefully constructed so that it would test the system thoroughly.
Results
The results were not unambiguous, in some situations the roll stability system prevented roll over, but in others it had the opposite effect.
