PROTON SAFETY - ELECTRONIC STABILITY CONTROL (ESC)

Have you ever experienced visiting PROTON showroom and the salesman seriously promotes PROTON car by talking about ESC? Have you heard about ESC? If you do not know what is ESC all about...., don't worry, below is a brief explanation about the system :-

What is Electronic Stability Control?
Electronic Stability Control (ESC) is a safety feature that detects and prevents (or recovers from) skids. ESC can help keep the driver from losing control of the car in a panic swerve (oversteer/understeer) or when driving on slippery roads.

How ESC works
ESC uses sensors in the car (wheel speed sensors, steering angle sensors and yaw rate sensors) to determine which direction the driver wants the car to go, and compares that to which way the car is actually going.

 

If the system senses that a skid is imminent or has already started -- in other words, that the car is not going in the direction the driver is telling it to go -- it can apply the brakes on individual wheels to bring the car back under control. Because the system can brake individual wheels, whereas the driver can only brake all four wheels at once. ESC can recover from skids that human driver cant. In many case engine throttle also is reduced.
