EPB Function

• Manual apply of EPB switch in stand still condition.
• Clamping force control; When parked on less than 8% slope with engine running, it is applied with Reduced Clamp Force (RCF); Except for RCF condition, it is applied with full clamp force.

• If EPB is applied on less than 8% slope with engine running, it is applied with reduced clamp force.
• When switch is pulled for more than 3 sec, it is clamped to full clamp force.

• Releasing EPB manually by switch
• To prevent danger situation, it can be released only when ARC is fulfilled.

Additional Release Condition (ARC)

• To prevent unintentional release of EPB, there is condition to be met before releasing;

Example: IGN On + [Brake Pedal pressed]

Child Safe (Release Inhibit)

• With ignition switched off, EPB cannot be released.

• EPB is released automatically when driver tries to move.
• EPB is released when accelerator pedal is depressed with gear shifter in moving position. (D or R)

  ; Driver seatbelt should be buckled.

  ; Driver side Door + Hood + Trunk should be closed.

• When EPB switch is pulled in dynamic condition, deceleration is realized by sending request via CAN to the ESC.
• ECD means deceleration will be done via the ESC system, not by EPB Actuator;

  Applied to the vehicle with ESC only.

• This function is for vehicle with no ESC or failed ESC. When EPB switch is pulled in dynamic condition, dynamic deceleration is generated by EPB actuator.
• Clamp force will be controlled to avoid locking of the rear wheels and ensure vehicle stability.

• With switching off ignition, EPB will automatically apply the brakes.
• Auto Apply is disabled when Auto Hold switch is switch off.
• The auto engage feature does not activate if the power switch is turned off while the EPB switch is pressed.

• If vehicle rolls away, EPB gets reapplied.

  ; Vehicle movement is monitored via wheel speed.

  ; It can be active until CAN signal is available (3 min)

• After detection of hot brakes, EPB will reapply from closed brake state to compensate for loss of clamp force during cooling of the brakes.
• Activation condition: over 350°C

• EAR checks for an external demand to apply the brake and reacts according to that demand;

  With EAR, Auto Hold → EPB takes over possible

• Return the spindle nut fully for pad replacement

  ; This mode can be entered via hand tool connected to vehicle with OBD2 connector.

  ; Piston can be pushed in after entering Pad change mode

This is how to operate the parking brake when there is no wheel speed signal because of malfunction. Braking force can be applied while the vehicle is in motion to slowly decelerate. If the EPB switch is continuously pulled, then the parking brake can be engaged with maximum force.

EPB is automatically released when gear shift lever is moved from P position;

Engine on + Brake pedal condition is necessary.

EPB is automatically released when gear shift lever is moved from Neutral position to moving position. (D or R)

; It does not get released if the gear shift lever is moved to P or passes through N rapidly.

; Engine on + Brake pedal condition is necessary.
