Why Electronic Stability Control (ECS) In Cars?


ESC is a vehicle control system which comprises sensors and a microcomputer. It continuously monitors how well a vehicle responds to a driver’s steering input. Further, ESC selectively applies the vehicle brakes and modulates engine power to keep the vehicle travelling along the path indicated by the steering wheel position.

ESC is proven to be effective in reducing the occurrence of single-vehicle and rollover crashes.

How ESC works?

Electronic Stability Control (ESC) uses the speed sensors on each wheel and the ability to brake individual wheels that are the basis of anti-lock brakes.

ESC adds a control unit that monitors steering wheel angle and vehicle rotation around the vehicle’s vertical axis.

 This unit uses the steering and rotation information to detect. Then ESC automatically brakes the appropriate wheel to help the driver maintain control. In many cases, engine power also is reduced.

Sensors on the car monitor the direction of travel and steering wheel position. If a hard steering manoeuvre occurs the technology will automatically brake individual wheels and help bring the car back on track.

ESC (Electronic Stability Control) can help a driver maintain control by:

  • Correcting oversteering or understeering
  • Stabilising the car during sudden evasive manoeuvres
  • Enhancing handling on gravel patches
  • Improving traction on slippery or icy roads

Pros of ESC (Electronic Stability Control)

  • ESC can control one-third of the fatal accidents from taking place
  • The sensors present in the system are programmed to respond post any detection of loss of control
  • In a few ESC systems, the engine power can also be reduced
  • The system is so efficient that drivers do not need to search for steering corrections
  • This works very well for Indian roads where accidents are so frequent

Cons of ESC (Electronic Stability Control)

  • Electronic Stability Control may or may not prevent a rollover.
  • Will not apply hard braking or steering automatically.

Good News

The good news is that the ESC technology will become mandatory on Indian cars by 2023.
