Operation of the stability control system
Page 25 | Listen in audio
The stability control system (ESC) is an essential safety feature in modern vehicles. It helps keep the car under control in emergency situations such as sharp turns, sudden changes in direction or slippery road conditions. ESC is an electronic system that constantly monitors each wheel speed, steering wheel position, lateral acceleration and other factors to determine if the vehicle is moving in the driver's intended direction.
If the system detects a loss of control, it automatically intervenes to help correct the vehicle's trajectory. For example, if the car starts to skid around a corner, the ESC can reduce engine power and apply the brakes to one or more wheels to help keep the car in the lane. In other situations, ESC can help prevent rollovers by monitoring the vehicle's lean and individually applying the brakes to stabilize it.
The ESC is made up of several components, including wheel speed sensors, lateral acceleration sensors, an electronic control module, and brake actuators. Wheel speed sensors monitor the speed of each wheel and transmit this data to the electronic control module. Lateral acceleration sensors measure the lateral force applied to the vehicle and transmit this data to the electronic control module.
Based on this information, the electronic control module calculates the intended trajectory of the vehicle and compares it with the actual trajectory. If there is a significant discrepancy between the two, the electronic control module steps in to help correct the vehicle's trajectory. It does this by individually applying the brakes to one or more wheels and reducing engine power if necessary.
ESC is an important safety feature that can help prevent accidents and save lives. It is important to remember that ESC is not a substitute for responsible and safe driving. Drivers should always follow traffic rules, maintain a safe speed and be aware of road conditions. Combined with responsible driving, ESC can help make the roads safer for everyone.
