Hella 8303EN_GE (2004-09) 1 General Information In this document the Keyless GO and Start System is introduced. Keyless Entry Systems are the consequent development of well-known Remote Keyless Entry Systems (RKE), the usage of the key fob with button pressing is still possible, but not necessary anymore to enter the vehicle or to start it. With the Hella Components UID, LF antennas and Keyless Start ECU it’s possible to equip a vehicle with only a few components and realize this very convenient and luxury feature. The ECU is built together with Continental Corporation Germany. Hella is the Engineering Distributer AND Designer for the part that is to be approved. The Model Name of the described ECU is: MARS Keyless

Hella 8303EN_GE (2004-09) 2 LF- Performance in Typical Application In the MARS EIS ECU the Hella LF Driver Part is connected with Hella LF Antennas. A UID – also manufactured from Hella – is to be found inside or outside the vehicle, whether a special occasion happens. Here are some examples: - Passive Entry / Exit A Person with the UID nears to the locked vehicle. If he grabs the door handle capacitive unlock sensor is activated and the complete Keyless Entry Protocol is started. The side LF antenna is transmitting LF data and a carrier signal, which can be recognized and judged by quantity (RSSI-measurement) by the UID. The measured field strength is sent to the ECU and is judged. If the magnetic field strength is high enough (a certain border is reached). The doors will unlock. The additional LF communication guaranties the functionality, that only the valid key OUTSIDE the vehicle authenticates the system to unlock the car passively. If the magnetic field strength is not high enough (e.g. the UID is too far away from the vehicle, the border is not reached), the UID shuts down again and waits for the next LF Data. The vehicle is still locked. A Person with the UID is leaving the vehicle. If he touches the capacitive lock sensor at the door handle, the complete Keyless Exit Protocol is started: The side LF antenna is transmitting LF data and a carrier signal, which can be recognized and judged by quantity (RSSI-measurement) by the UID. The measured field strength is sent to the ECU and is judged. If the magnetic field strength is high enough (a certain border is reached). The doors will lock. The additional LF communication guaranties the functionality, that only the valid key OUTSIDE the vehicle authenticates the system lock the car passively. If the UID is left inside the car, the car won’t lock. If the magnetic field strength is not high enough (e.g. the UID is too far away from the vehicle, the border is not reached), the UID shuts down again and waits for the next LF Data. The vehicle is still open. - Passive Start A Person with the UID inside of the vehicle is pressing the Start-Stop-Switch. The Start-Stop-Switch activates the complete Keyless Start protocol: The interior antenna is transmitting the LF Data and a carrier signal, which can be recognized and judged by quantity (RSSI-measurement) by the UID. The other two interior antennas IN1 and IN2 transmit two additional carrier signals sequential. If the magnetic field strength of one of these transmits is high enough (a certain border is reached) then the UID authenticates the system to start the vehicle. If the magnetic field strength of all antenna transmits are too low (the field strength border is not reached, maybe the UID is laying outside or is held 10cm outside the vehicle) the car won’t start.

Hella 8303EN_GE (2004-09) 5 LF-Antennas The LF antennas generate the magnetic field that is needed for wireless communication between car electronic components and the UID that is carried with by the end-user. Each LF antenna that is plugged to the ECU is a LCR resonant circuitry: Fig. 16 LF Antenna, RLC resonant circuit Fig. 17 LF-Antenna, Impedance Z The LF antennas transmit the LF challenge signals (data) and the LF carrier wave signals. They are activated by the MAR EIS ECU using a controlled current. ALL LF Antennas have the same efficiency. The efficiency of all antennas is Hmax(@l=1m, @IANT=500mA) =77,5 dBµA/m. The general measurement of the efficiency of the antennas is shown is this picture:

Hella 8303EN_GE (2004-09) 6 Software for LF Transmitter Mode (Data and CW) for Homologation The LF Transmission for Homologation Purpose is an original LF Scan for a Passive Entry / Passive Exit action. The LF driver IC is especially made for driving an electric current at f=125kHz with a certain modulation and bit structure. Only short burst shall be sent out at different antennas channels in a certain timing. It is NOT possible to drive the antennas with a continuous carrier signal. The maximum of carrier (unmodulated) signal length that can be driven – and is driven for magnetic field strength measurement in the UID – is tcarrier=5,2ms. The SW of the ECU has two small changes in comparison to the mass production software: First: As the setup is connected to the power supply (V = 12V / I = 5A) and the lever is set to “Open – LF Mode”, an LF data scan is automatically generated on all four antennas with a time gap of 23ms between each antenna and a pause of 273ms after the last antenna. So, a continuous repetitive scanning is created, that is similar to the system reaction, as if a person is grabbing the door handle to enter the locked vehicle every 370ms with not having the UID in detection range. Second: As the setup is connected to the power supply (V = 12V / I = 5A) and the lever is set to “GND – IMMO Mode”, an Immo transponder start is automatically generated on the IMMO-antenna every 3,25s. After a successful keyfob answer the LED is powered for 100ms. IMPORTANT NOTE: This Second functionality is only allowed to be used 1 Minute and then a power down of 2 Minutes is needed. Otherwise the protocol won’t finish completely and the LED won’t light up due to warmup of the ECU. In mass production / series such a stress never would occur! To switch between those two functions simply turn the lever in the designated position and perform a power-on reset. There are no other SW changes to the mass production software. The scope-diagrams in the following are taken by a simple AIR-COIL (15 windings, 4cm diameter), which is positioned near to the test setup. This coil is connected to a 150MHz Scope Probe (x10). With this SW FOUR ANTENNAS are mentioned to the system.
