Confié à titre de secret d'entreprise. Tous droits réservés. All rights reserved. 1.1 Operation of BASIC Key 1.1.1 Access permission with BASIC Key The locking and drive permission system BR166 (3333.4/5) incorporates a function which enables the Proprietary data, company confidential. locking and unlocking of the doors. There are two separate buttons each one for lock and unlock the vehicle. All vehicles with a boot lid are equipped with a third button for unlocking the boot lid. The key is provided with a fourth button to activate the “PANIC” function for vehicles intended for the US market. The function is activated by pushing a button, the method of button pushing determines the function activated on the vehicle, e.g. prolonged pressure on the button initiates an IR comfort function. If messages are discharged from the key, the access permission information is sent via radio waves (HF) and redundantly via infrared (IR) from the key to the vehicle. The so-called comfort signals are special functions which require visual contact with the vehicle. Upon pressing the button for an extended period, . . these signals are sent via IR signal only after the standard access permission message. sondere für den Fall der Patenterteilung oder GM-Eintragung.

Alle Rechte vorbehalten, insbe- wertung und Mitteilung ihres Inhalts nicht gestattet, soweit HF communication via 3-channel operation: The access permission message is sent sequentially on 3 radio channels adjacent to one another within the permissible ISM band. The radio receiver installed within the vehicle is able to receive the message discharged from the key on all 3 channels, evaluate it and send an appropriate control message to the central locking system. 1.1.2 Drive permission with BASIC Key After the key is pushed into the EZS (electronic ignition switch) a cryptographically, bidirectional communication by infrared light is initiated. As there is a successful authorization of the key the engine of the vehicle can be started. . . 1.2 Operation of KEYLESS GO Key The KEYLESS Go key model is equipped with all of the BASIC model functions. Additional the KEYLESS GO model only facilitates full utilisation of the drive permission system function on the vehicle without active operation of the key. This means that one can lock and unlock the vehicle (access permission) without operating the key and activate and deactivate the immobiliser (drive permission) without placing the key in the ignition switch. It is only necessary to carry the key in order to be identified as an authorised vehicle user. In addition to the basic variant, the keyless go key is expanded to include an LF receiver component, comprising of inductive antennae which create the three spatial directions x, y and z, and an associated LF receiver ASIC. Additionally, the keyless go variant of the key is equipped with a special HF ASIC, which facilitates bidirectional HF communication. form 659.02 First Draft 23.10.2009 Version 1.02 MARQUARDT GmbH Schloßstraße 16 Department APDA1-RI File D 78 604 Rietheim – Weilheim Editor U.

Confié à titre de secret d'entreprise. Tous droits réservés. All rights reserved. 1.2.1 Access permission with keyless entry The keyless access permission (keyless entry) is initiated by the vehicle user activating the vehicle door handle. This causes the vehicle to send an inductive wake up message. On receiving this, the key starts in active mode. The vehicle now sends further unmodulated, inductive fields which enable the key to ascertain its position in relation to the vehicle on the basis of field strength measurements. Proprietary data, company confidential. Bidirectional HF communication follows, in which cryptographically encrypted authentication data is transferred between the key and the vehicle. If the key is outside the vehicle, the vehicle is locked or unlocked following transferral of the correct data. 1.2.2 Drive permission with keyless go In principle, when activating the start/stop button for a keyless engine start, the same process runs as that described for access permission of the BASIC model. The difference here is that the key must be located inside the vehicle, but needs not to push into the EZS (electronic ignition switch). . . The presence of the key inside the vehicle is verified on every 5km driven, and on driving away. The process that runs here is similar to the engine start process, although shorter. The cryptographically encrypted authentication between key and vehicle is accomplished by a bidirectional sondere für den Fall der Patenterteilung oder GM-Eintragung.

With respect to bidirectional HF communications, these are processed in a frequency-modulated (FSK) format, in the ISM band on 433.92 MHz in Europe and 315 MHz in the USA.
