What does the electronic stability control system monitor in a vehicle?

The electronic stability control (ESC) system is designed to enhance the safety and control of a vehicle during dynamic driving conditions. Its primary function is to monitor and manage the vehicle's traction level and rollover threshold.

When a vehicle begins to lose traction because of slippery surfaces or aggressive maneuvering, the ESC system detects this instability by using various sensors that monitor factors such as wheel speed, steering angle, and lateral acceleration. If it identifies that the vehicle is veering off its intended path or is at risk of rolling over, the system automatically applies the brakes to specific wheels and modulates engine power to assist the driver in regaining control.

This proactive approach helps prevent skidding, increases stability, and enhances vehicle handling in challenging driving situations. Therefore, the focus of the electronic stability control system is on maintaining traction and preventing rollover, which makes the choice regarding traction level and rollover threshold the most accurate answer.
