Electronic stability control

Electronic stability control (ESC) is a technology designed to improve the safety of vehicles by detecting and reducing instances of skidding or loss of control. It uses a combination of sensors, microprocessors, and actuators to monitor the vehicle's behavior and automatically apply brakes or adjust engine power to help the driver maintain control during emergencies or challenging driving conditions.

It uses a combination of sensors, microprocessors, and actuators to monitor the vehicle's behavior and automatically apply brakes or adjust engine power to help the driver maintain control during emergencies or challenging driving conditions. ESC is especially effective in preventing rollovers and spinouts, which are often caused by oversteering or understeering. This technology has been widely adopted in modern vehicles due to its proven ability to enhance vehicle stability and reduce the risk of accidents.
