Huf Hülsbeck & Fürst 04.09.06 PDET/Witte Functional Description / User Manual for Comfort Access System Huf Hülsbeck & Fürst 04.09.06 PDET/Witte 1. Functional Description - Comfort Access System (CA) 2. General system description The CA-system enables convenient utilization of the vehicle. To use the vehicle, the driver only needs to take the key along with him/her. The vehicle communicates with the system inductively via antennas. These antennas are driven inductively with a frequency of 125 kHz. The system's range is limited in a defined fashion by damping the body sheet metal. In the vehicle interior, the ranges of the various antennas overlap, which enables location of the key. 3. Passive access control An approximating of the hand to the door handle, as well as by pulling the door handle is recognized over sensors. The door handle give this information over a CAS-Bus telegram to the CAS and at the same time the handle sends over 125 kHz Uplink to the passive key. In the case of a valid authentication the vehicle is unlocked or locked. (Detection radius of approx. 1... 1.5 meters around the door handle) 4. Passive Go (start/stop) The system provides the function which enables starting/stopping the engine without key actuation. The prerequisite for starting the vehicle is a key allocated to the vehicle, which is taken along by the user and is clearly inside the vehicle. By actuating the starting device, the driver starts the identification process, i.e. the PGS control unit issues a request for a valid key inside the vehicle. The key returns an appropriate response to the PGS control unit. In case of successful identification of the key, the vehicle is started and the immobilizer is deactivated. Huf Hülsbeck & Fürst 04.09.06 PDET/Witte 5. 1.4 Cabrio function procedure Since at the cabrio roof no trapping protection is available, it must be guaranteed that a valid passive key is in close range of the vehicle before and/or during the roof closes. With the help of a LF Ping telegram, which is sent over the door handle antennas and the bumper antenna, the CAS looks for the passive key for the start and during the Comfort latches procedure. Detection radius is approx. 3 meters around the door handle. If the passive key leaves the receipt radius, the function is stopped. The function only accomplished if at the key the locking switch is pressed and the key is in the range of the LF antennas. Huf Hülsbeck & Fürst 04.09.06 PDET/Witte 6.
