ESC stands for “Electronic Stability Control”. The system is used in vehicles from Hyundai, Chevrolet, Škoda, Kia and Lada, among others. It optimizes the handling of the vehicle and can prevent accidents. In addition, it helps the driver to keep the intended lane. It’s a complex innovation that often includes additional features, including advanced emergency braking, roll stability control and trailer stabilization assistance.
How the ESC works
The operation of the ESC is closely linked to other driver assistance systems, such as ABS and ASR. As soon as the key is turned in the ignition lock, it switches on automatically. The vehicle’s actual path is constantly compared to the intended course to correct the difference if necessary.
Driving behavior is recorded using the steering angle sensor, the accelerator pedal position sensor and the brake light switch. At the same time, the yaw rate sensor, the longitudinal and lateral acceleration sensors and the wheel speed sensors provide data on the vehicle’s actual lane.
The ABS works with the ESC to maintain the planned lane by applying braking force to specific wheels. In addition, commands to limit the engine torque are sent to its control unit.
As soon as the system is switched on, the corresponding warning lamp lights up on the dashboard. To turn off the system, press the button on the center console.
