• Rollover Warning System

• Active Roll Control Suspension System

Rollover Rating Program• Introduced by NHTSA (National Highway Traffic

Safety Administration) USA in 2004

• A methodology for determining which cars are most likely to rollover and to assign rollover percentage risks for specific vehicle models

• Rollover rating of a vehicle is obtained based on SSF (static stability formula) value and putting the vehicle into the real-world driving simulator for maneuvering tests

Chances of Rollover

Rollover Warning Systems

• RWS is used to determine when a potential rollover condition exists based on real information such as vehicle weight, speed, steering wheel input, lateral acceleration and tire force, etc.

• When a potential rollover condition exists drivers are bombarded with messages and instructed to reduce steering input or to decelerate the vehicle
