The Development of an Active Roll Control System for Heavy Vehicles

1.1. Background Studies have shown that most rollover accidents involve heavy articulated vehicles, and occur on highways [1]. Three major contributing factors to rollover accidents have been identified: (1) sudden course deviation, often in combination with heavy braking, from high initial speed; (2) excessive speed on curves; and, (3) load shift. The accidents are relatively frequent, and the estimated average cost to operators is between USD 120,000 and 160,000 [2].
