ESC stands for Electronic Stability Control. This system is installed on Hyundai, Chevrolet, Škoda, Kia, Lada, and other vehicles. It improves the car’s road holding and helps prevent accidents. It also assists the driver in maintaining the intended path. It is a complex solution that often includes additional functions such as emergency braking assistance, rollover mitigation, and trailer stability assistance.
HOW THE ESC OPERATES
The ESC works closely with other driving aids such as ABS and ASR. It automatically turns on when the key is turned in the ignition switch. It continuously compares the vehicle’s actual trajectory with the intended one to eliminate any difference if necessary.
Readings from the steering wheel angle sensor, accelerator pedal position sensor, and brake light switch are used to monitor the driver’s actions. Meanwhile, the yaw rate sensor, longitudinal and lateral acceleration sensors, and wheel speed sensors provide information about the car’s actual path.
The ABS works in combination with the ESC to maintain the intended trajectory by applying braking force to certain wheels. Additionally, engine torque limitation commands are sent to the engine control unit.
When the system is activated, the corresponding indicator light flashes on the dashboard. The system can be deactivated by pressing the button on the center console.
