When the mechanical Key is operated for a lock operation then for a duration of "MLockTimeoutTime" (3 sec) the BCM shall monitor the corresponding knob's state; if the knobs are in lock state within this MLockTimeoutTime then a central lock operation is issued; if any knob remains in unlock state at the end of this MLockTimeoutTime then no central lock operation is issued.
  2. When the mechanical Key is operated for an unlock operation then for a duration of "MUnlockTimeoutTime" (3 sec) the BCM shall monitor the corresponding knob's state; if the knobs are in unlock state within this MLockTimeoutTime then a central unlock operation is issued; if any knob remains in lock state at the end of this MLockTimeoutTime then no central unlock operation is issued.

  4. After crash is activated, Central Lock and Auto Door Lock Function can not operate until Key off.

2. P_CrashInput signal (PWM)

  1. Before crash: When crash condition is not present, input is made as follows ( b_Crash = Off at P_CrashInput signal event is as follows)

  1. After Crash:
  1. When crash happen, input is made as follow signal.
  2. BCM should be enabled (b_Crash = On ) when received at least one pulse during P_CrashInput signal appeared.

Auto Door Lock/Unlock Function

Auto Door Lock/Unlock Function

1. This function describes the following features

  1. Door Lock by Shift-Lever

  1. Vehicle Speed Option

  1) Vehicle Speed Auto Lock Condition

  1) Dining ignition on, and when any door is unlocked, if vehicle speed is exceeded the "AutoDoorLockSpeed" Km/h, output all doors lock.

  2) After output all doors lock, if any door is not locked, output all doors lock "AutoReLockNumber" times.

  3) Between each lock output, it have "AutoLockDelayTime" time gap.

  4) During "AutoReLockNumber" times all doors lock output, if all doors state are changed lock, stop this output.

  5) During vehicle speed is over "AutoDoorLockSpeed" Km/h, if any door is unlocked, output all doors lock, again.

  6) However after "AutoReLockNumber" times all doors lock output, even if any door is unlocked, before ignition off (b_IGNState = Off) or all doors is changed to lock, there is no additional lock output.

  2) Vehicle Speed Auto Lock State Release Condition

  1) After auto lock, it does not operate again. But in below condition, auto lock state is release and if it meet the Auto Lock condition, auto lock operate again.

  2) Any Knob state is changed to unlock (So, when vehicle speed is exceeded the "AutoDoorLockSpeed" Km/h, any knob state change to unlock, auto lock function is operate, again.)

  3) After Crash Unlock output (But, in Crash active state, Auto lock does not operate.)

  4) Ignition off (b_IGNState = Off)

  5) Vehicle Speed is below "AutoDoorLockSpeed" Km h, (So, if vehicle speed is exceeded the "AutoDoorLockSpeed" Km/h and any knob states are unlock, auto lock function is operate, again)

  3) Knob Lock Fail Condition

  1) After "AutoReLockNumber" times all doors lock output, failed Knob is enter the knob Fail mode.

  2) So, when meet vehicle speed Auto Locking condition again, that time it does not consider the previously failed knob (Auto Lock 3 times not operate.), However, another knob have a fail, operate Auto Lock 3 times.

  3) This failed knob state is release in below condition.

  4) The failed knob is changed unlock to lock.

  5) Ignition off (b_IGNState = Off
