The ESC is the acronym for Electronic Stability Control. The ESC is a braking system that combines the functions of a brake servo unit and the ABS (Antilock Braking System) equipment including ESP (Electronic Stability Program). The ESC is a technology that improves the safety of a vehicle's stability by detecting and reducing loss of traction. When ESC detects loss of a steering control, it automatically applies the brakes to help steer the vehicle where the driver intends to go. Braking is automatically applied to wheels individually. ESC incorporates yaw rate control into the ABS. Yaw is a rotation around the vertical axis. ABS enable ESC to brake individual wheels. The data from the way sensor is compared with the data from the steering wheel angle sensor to determine regulating action.
