R&D / Automotive Electronics 1. INTRODUCTION This document is the technical specification of the remote keyless entry (RKE) System for the car consisting of DPI (Daewoo Precision Industries,. LTD) receiver (RX), DPI transmitter (TX) and siren. The purpose of the DPI RKE system is to provide the remote control function and the anti-theft function in which it is installed and to prevent it from being driven by unauthorized users.

R&D / Automotive Electronics 3. RKE FUNCTION 3.1 DOOR LOCK / UNLOCK USING TRANSMITTER 3.1.1 TRANSMITTER LOCK / UNLOCK This system function by using two buttons of the valid Tx is shown at Table 1. Now we define the “VALID Tx” as the ID code (Fixed code + Crypto code) of the Tx is memorized by the Control Unit. Status A Unset B Set Button Function "UNLOCK" All door unlock, Hazard lamp blink twice, Disarming Mode "LOCK" All door lock, Hazard lamp blink once, Arming Mode [Table 1.
R&D / Automotive Electronics 3.1.2 TRANSMITTER DOOR / TRUNK This system function by using two buttons of the valid Tx is shown at Table 2. Now we define the “VALID Tx” as the ID code (Fixed code + Crypto code) of the Tx is memorized by the Control Unit. A Status Button set / unset "DOOR" Function all door lock or unlock according to lock_monitoring status B set / unset "TRUNK" operating trunk solenoid and chirp operating(0.05sec on / 0.45sec off) [Table 2.
R&D / Automotive Electronics [Figure 2. FUNCTION FLOW] 3.2 BURGLAR ALARM At the arming mode, if below signal input is recognized by the Rx, the burglar alarm (audible alarm (siren) and visible alarm(hazard Lamp) ) is activated 8 times during 28 seconds operated and 5 seconds paused. The alarm activating count is the option by customer.
R&D / Automotive Electronics If the above theft detection input is received at the arming mode, the type of theft is memorized at the Rx EEPROM. But the alarm duration is not prolonged even if theft detection signal is recognized during the alarm mode. That is, the Rx ignores the theft detection input until the alarm is finished.
R&D / Automotive Electronics 3.4 SAFETY LOCK(AUTO DOOR LOCK AFTER 30SEC) At the arming mode, if the door / trunk / hood open and the ignition on is not occurred during 30 seconds after all door is unlocked by the Tx unlock button or the Tx door button, then all door is locked again and the Rx also goes to the arming mode. At the case of the safety lock, even though the Rx goes to the arming mode, the EEPROM data of the Rx about alarm is not changed.
R&D / Automotive Electronics Active range requirements shall be met with the receiver mounted in the vehicle in its production intent mounting location and orientation. Range requirements are specified for open, flat, paved terrain, with fair weather (no rain or snow), temperatures between 0°C and 80°C, and fob height between 0.5 and 1.5 meters above the ground surface. Range shall be measured from the center of the vehicle, and is independent of fob orientation.
