|---|---|
|
ABS control function
|
• Controls brake fluid pressure when braking to maintain directional stability, ensure steerability, and reduce stopping distance.
|
|
Electronic brakeforce distribution (EBD) control function
|
• Constantly controls proper distribution of brake fluid pressure to the front and rear wheels according to vehicle load, road surface, and vehicle speed conditions to prevent early lock-up of the rear wheels.
|
|
TCS control function
|
• Controls traction to within the road surface friction limit and according to road and driving conditions to improve starting and acceleration performance, and safety.
|
|
DSC control function
|
• Suppresses strong over-steer and under-steer tendencies when turning by controlling engine output and braking of each wheel to assure driving safety.
|
|
Brake assist control function
|
• The brake pedal depression speed and force is calculated from the brake fluid pressure sensor signal. If it exceeds the specification, an emergency braking situation is determined and a higher amount of hydraulic pressure than the normal specified amount is generated in the hydraulic unit and supplied to each wheel based on the activation of each solenoid valve, pump motor, and pump.
|
|
CAN communication function
|
• Outputs the vehicle speed signal and DSC system warning control data via CAN lines.
|
|
On-board diagnostic system
|
• A function that allows important parts of the DSC control system to perform self-diagnosis. In case a malfunction occurs, the warning lights illuminate to alert the driver, and at the same time a DTC is stored in the DSC HU/CM.
• When a malfunction is determined as a result of the on-board diagnostic test, system control is suspended or limited to prevent any dangerous situation while driving.
|
|
Automatic configuration function
|
• When the ignition is switched to ON or the engine is started after the DSC HU/CM have been replaced, the DSC CM reads data from the instrument cluster via CAN communication to perform automatic configuration.
