System’s working principle

1. Normal Start Mode: The user enters the vehicle with the authorized smart key, treads the brake or clutch pedal (The KBCM ECU begins to detect the smart key at once) and presses the engine-start-stop-button (SSSW). ESCL unlock will be done when the KBCM successfully detects the authorized smart key in the vehicle. After the ESCL is unlocked, KBCM changes the power mode from OFF to Crank and then the EMS is wake up. After the initialization of the EMS the engine-anti-theft authentication between KBCM and EMS should be achieved while the engine starter begins to run. If the authentication is successful, the engine can be started under the control of EMS. If the user starts the engine not in the power mode OFF but in the power mode ON, the start process could be simplified, because the ESCL should be already unlocked, the EMS works in normal way and the engine-anti-theft authentication is finished. The user presses the engine-start-stop-button when all of the conditions for engine start are satisfied, which are listed as below:
   • The brake pedal is treaded, and
   • The gear shift is in P or N.

The engine won’t be started if the conditions are not satisfied when the engine-start-stop-button is pressed. But the power mode will be changed according to the power mode management.
The response time for engine start that is specially focused is the interval from the moment the engine-start-stop-button is pressed to the moment the engine starter begins to work. Following is the proper operation process: the user treads the brake pedal first and then presses the engine-start-stop- button. As to the normal response time of human being, there is at least 100ms between the two actions above. The KBCM takes less than 100ms to detect the smart key. Therefore the detection and authentication of the smart key should be finished before the user presses the engine-start-stop-button.

• Emergency Start Mode：If the battery in the smart key is so weak that the engine cannot be started in normal way, the KBCM system might start the engine with emergent method. By emergency start the smart key should be close to the appointed position where IMMO module mounted is, when the user presses the button. The IMMO coil and the transponder chip in the smart key communicate with each other in low frequency under the control of the KBCM. After the information of transponder is extracted, the engine anti-theft authentication between KBCM and EMS will be done. If the authentication is successful, the engine can be started under the control of EMS. The only difference is the method to detect the smart key. By the normal start the authorized smart key is detected with interior LF antennas while by the emergency start with the IMMO coil. The location of the smart key is particular for the emergency start. To assure the regular communication between the IMMO base and the smart key, the smart key must be placed within the inclination of 30° from the center axis of the coil and within the distance of 30mm from the center of the coil.

• Vehicle Anti-Theft: There are four Anti-Theft status: Disarmed, Pre-armed, Armed, Alarm status, Default status is Disarmed status, when system power mode is OFF mode, if execute valid lock door action(Mechanical key/PKE/RKE/T-BOX lock five doors or Auto Relock successfully), Anti-theft status shall go to Pre-armed status, after skip to Pre-armed status, if keeping time of Pre-armed status is more than 15seconds, skip from Pre-armed status to Armed status. During Armed status, if any one condition of below conditions is fulfilled, skip from Armed status to Alarm status:

  • Any one door of five doors is opened from closed or CAN message HoodSts_F_Pbox value (shall store to EEPROM) is from 0x0:Closed to 0x1:Open
  •  Mechanical key unlock successfully
  • Anti drag vehicle warning signal is from invalid to valid

• When skip to Alarm status:

  •  KBCM send LIN message(InSts=1 and send SoundCmd=1) with cycle time 400ms and duty cycle 50%) for 28seconds,
  • KBCM shall activate turn right light and turn left light blinking for 28seconds (frequency is 2.5Hz ,duty cycle is 50%),
  • then pause 2seconds, KBCM send messages (turn light is off and SoundCmd=0 and InSts=0), which is one alarm cycle (28s+2s=30s), shall keep 6 alarm cycles, total time is 3minutes. When 3 minutes is over, KBCM send messages(InSts=0 and SoundCmd=0) and turn off turn right light. When in Alarm or Armed status, if any one condition of below conditions is fulfilled, skip to Disarmed status:
  •  PKE/RKE/T-BOX unlock successfully
  • System power mode has changed to (ACC or ON) mode
  •  Trunk is unlocked by PKE/RKE

• Body Control Mode: KBCM shall active door locking motor or lighter or wiper motor by hardware inputs or CAN/LIN message, when user is close to vehicle and press unlock/lock button of smart key or touch unlock/lock switch of door handle, KBCM shall control five door locking motor to unlock or lock the door, and when light switch is active, KBCM shall turn on corresponding light if activation condition is fulfilled, besides the KBCM also can control front and rear wiper or wash motor, Anti-Drag Vehicle detection function base on its activation conditions.

• System’s safety Instructions
  The system includes multi-layers encryption and decryption technique. The part of key certifying is using the mature technique of RFID certified by ATMEL Company. The communication between key core and immobilizer is using low level communicating mode. System certify the key by first step and then ECU, the repentance of key is low to 1/280. Only when be authorized, the system could enter the matching process, doing the operation like adding or deleting key, replacing system parts and so on. There will be a new certifying process when each igniting, the certifying data is produced randomly. Title: Partial model information document no. B30 KBCM-00 Type: A30,B30, AB30

• Preventions of accident starts : When someone tried to start the vehicle, if the security data control system did not pass certification, the engine control unit (ECU) will be closed Circuit Cypriots did not start the ignition. The normal operation of the engine will not be able to meet the conditions, the vehicles failed to start. When someone tried to start the vehicle, it is first necessary that the correct smart key is in the car, and the smart key should do data encryption certification with KBCM ECU, if the certification is passed, then KBCM ECU will start the encryption certification with EMS, after this certification, the encryption certification between anti-theft controller and ECU control module can be done. After the adoption of authentication, engine control unit will provide continuous operation of the engine condition, the vehicle can start. When someone attempts to use other means of authentication data through encryption, he needs to know encryption algorithm and key. Encryption algorithm is a company confidential which composed by 80 bytes.

• The installed position: B30 KBCM ECU is installed under the central IP. Transponder is integrated assembled in the smart key. B30 immobilizer driver (also used for LF antenna) is installed under the cup holder. After the controller and LF antennas are installed, insert the wiring harness into the right place.
