Roll-over mitigation is a feature integrated into Electronic Stability Control (ESC) systems in vehicles. ESC, also known as Electronic Stability Program (ESP) or Dynamic Stability Control (DSC), is a technology designed to improve a vehicle’s stability by detecting and reducing loss of traction (skidding).
Roll-over mitigation specifically addresses the risk of a vehicle tipping over or rolling over during extreme maneuvers, such as sharp turns or sudden lane changes. This feature utilizes sensors to monitor various parameters such as vehicle speed, steering angle, lateral acceleration, and yaw rate. If the system detects that the vehicle is approaching a critical threshold where there’s a potential for a rollover, it intervenes by applying selective braking to individual wheels and sometimes by reducing engine power to help stabilize the vehicle.
By selectively braking certain wheels, the system can counteract excessive lateral forces and help keep the vehicle stable, reducing the likelihood of a rollover. Roll-over mitigation is particularly useful in SUVs, trucks, and other high-profile vehicles that have a higher center of gravity and are more prone to tipping over during aggressive maneuvers.
Overall, roll-over mitigation, as a part of the ESP system, contributes to enhancing vehicle safety by preventing accidents resulting from loss of control and rollovers.
