An Electronic Stability Program (ESP) helps master critical driving situations; when the vehicle suddenly over-steers during cornering or when sudden evasive action is required, for instance. The system detects skidding movements within fractions of a second and can take corrective action. ESP systems not only function when road conditions are good, but also on wet, icy, and/or unpaved roads. Technically speaking, the ESP system combines the Anti-Lock Brake Block System, electronic braking pressure distribution, ASR / Anti-slip-control and yaw control.
