Vehicle Stability Assist (VSA)
Should the car deviate from its correct path, VSA activates to bring the car back on track.
Vehicle Stability Assist (or Electronic Stability Control) is designed to anticipate when the car is being driven either deliberately or inadvertently in such a way that a loss of front or rear tyre grip is about to occur.
During cornering, VSA determines if the car is deviating from its correct path.
The system monitors the speed of the car as well as the relative speed of each wheel, the amount of turn on the steering wheel and the yaw and lateral G-forces on the vehicle. Should the car deviate from its correct path, VSA activates to bring the car back on track by applying the brakes to any individual wheel or adjusting the engine output.
Traction Control - Enhancing VSA
Traction Control is part of the VSA (Vehicle Stability Assist) system.
When one or both driving wheels has insufficient traction due to a combination of throttle opening, cornering force and low grip levels of the road surface, the Traction Control system will automatically reduce engine power until traction is re-established.
