ESP System Description

ESP
The ESP system consists of the electronic control/hydraulic unit, steering angle sensor, lateral acceleration/yaw sensor and wheel speed sensors. When the vehicle is in a turn, the ESP looks at the steering wheel angle sensor value and monitors the wheel speed of the inner and outer wheels to ensure the values are plausible. The steering angle sensor also measures the speed at which the steering wheel is turned.

The ESP control module is very similar to the ABS/ASR module. The ESP is comprised of several other systems, namely the HBA, ABS, TCS (ASR), EBD and FZR systems.
