ABS, electrical stability control (ESC), and traction control are paired together in most modern cars to improve traction. And so that the driver maintains control of the vehicle. The ABS programming gets connected to the traction module and ESC system. Take swerving left to avoid impact, for instance, the steering angle sensors detect where the car's front wheels direction, the stability control module determines the intended path and strives to correct it by determining if you oversteered or understeered using the yaw rate sensors. The wheel sensors detect the change in speed or if the wheels are sliding, this information is deciphered by computer programs that initiate the braking system.
