This includes analyzing the vehicle’s motion compared to the driver’s intended path and provides Roll Stability Program (RSP) and Yaw Control (YC). The last is the more advanced functions of the ESP.

This includes improving traction during acceleration and help aid lateral stability while driving through curves.

The second technology is Automatic Traction Control (ATC) which provides standard ABS functions. If it notices this, the system will intervene use Pressure Modulator Valves (PMVs) to adjust and/or pulse the brake pressure. The first is the Electronic Stability Program called “ESP”, which uses wheel speed sensors to monitor four wheel-ends to determine wheel slip or wheel lock-up during braking. This ABS has 3 pieces of technology used to do this. This is used to control the air brakes on medium and heavy duty trucks, tractors, and buses. Then Bendix ESP EC-80 Electronic Control Unit (ECU) is a member of the Bendix branded Antilock Braking Systems (ABS).
