Driving skills and Electronic Stability Control
One of the first things a novice driver asks is: “Do I turn into the skid or away from it?” With Electronic Stability Control, this decision is made for us. When a vehicle begins to skid during a cornering maneuver, the skilled driver steers into the direction of the rear wheels and modulates the throttle to control the skid. Electronic Stability Control program (ESC) operates with no action on the part of the driver. When activated the stability control program reduces engine rpm and applies braking to the appropriate wheels to eliminate the skid.

The Electronic Stability Control (ESC) program uses the Anti-Lock Brake System (ABS) and Electronic Throttle Control (ETC) to maintain vehicle stability in a cornering maneuver. The ESC program requires the communication between the Engine Control Module (ECM) and ABS controller. This communication takes place on the Controlled Area Network (CAN) buss of the vehicle. The program uses input from the following sensors: steering wheel position, throttle pedal position, throttle position, engine speed, brake switch, wheel speed, yaw and lateral acceleration.

Terminology: It is all about Physics
The thrust angle is measured on the Z axis to align the axles to the chassis centerline, both parallel and perpendicular.

Acceleration/deceleration is linear force generated on the Z-axis that can affect vehicle stability, if impr...
