F1. Summarize
With the rapid development of electronic information technology, the electronic information technology, data
communications technology, sensor technology, control technology, computer technology and vehicle network technology
and others are used in modern automobile anti-theft technology, promoting it highly intelligent, diversified function.
Electronic security controller is the most widely used automobile anti-theft devices. KOSTAL KBCM is the most effective
controller among this kind of product; it is locking the engine ECU to achieve security purposes.
F2. System components
Kostal KBCM is mainly made up by smart key, IMMO driver and LF antenna, controllers, tester and status indicators,
among which the controller is the core of the anti-theft and Body control system
F3. 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:
a) The brake pedal is treaded, and
b) 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.
2) 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
