1. UTeM’s Active Roll Control (ARC) Suspension System

2. Vehicles lean when cornering due to the weight transfer imposed by lateral acceleration acting on the suspension. Factors contributing to the roll angle of the vehicle include vehicle height and suspension stiffness.
The excessive roll angle due to extreme cornering can cause rollover
ARC system uses hydraulic/pneumatic and electronic technology to reduce or eliminate the vehicle roll angle in cornering, which improves handling. This improvement to vehicle handling can help reduce rollover risk.
