1. ESP (Electronic Stability Program)
ESP system contains the ABS (Anti-Lock Brake System), ABD (Automatic Braking Differential),
ASR (Acceleration Slip Regulation), Cornering Control and HBA (Hydraulic Brake Assist System)
functions.
▶Cornering Control (Understeer and Overersteer) Function
This function controls the vehicle stability by applying the braking pressure on each wheel
according to the yaw rate, lateral sensing value and driver’s steering wheel control.
▶HBA (Hydraulic Brake Assist System) Function
HBA (Hydraulic Brake Assist) system helps in an emergency braking situation when the driver
applies the brake fast, but not with sufficient pressure, which leads to dangerously long braking
distance. ECU recognizes the attempt at full braking and transmits the signal calling for full brake
pressure from the hydraulic booster.
