Dyanmic Stability Control is another name for Electronic Stability Control (ESC).

Electronic Stability Control (ESC) works by using information from many vehicle sensors such as Yaw rate, Acceleration, Steering Angle and Wheel speed Sensors. With this infomrmation, the the ESC system constantly compares the driver’s intention with the vehicle’s actual behavior. A central microcomputer analyzes the incoming data. When instability is detected, ESC immediately triggers a response to provide stability, automatically braking any of the four wheels and/or adjusting engine torque.

A revolutionary active safety technology, Electronic Stability Control (ESC), serves as a vehicle's sixth sense by anticipating crashes before they occur and automatically intervening to prevent them.
