It allows the user to mobilize or immobilize the motorcycle by use of a valid remote key. Its available for three different RF- carrier fre-
quencies: 315,0 MHz, 433,92 MHz and 434,42 MHz. However, this descriptive text is mainly oriented to the required facts concerning the wireless LF- and RF- interface homologation.The KR-system is speci-
fied for a temp.- range of Tamb = 20 to 85C. The KR-system consists the two main components:
BMW motorcycle Keyless Ride ECU BMW Keyless Ride ID Device The motorcycle mobilization/ immobilization followed by ignition ON/OFF can be performed by pushing the button (S0) of the KR-ECU placed in the cockpit at the steering column. The KR-ECU is supplied in the voltage range 9,0 to 16,0 V derived from the motorbikes 12V-battery. The functional condition the motorcycles velocity must be less than 2 km/h. This information is delivered by CAN messages monitored and controlled by the ECU controller.

Date: 04.Nov. 2013 Revision: 02 Seite 4 von 21 Huf Hlsbeck & Frst Technical System Description Keyless Ride BMW Motorrad 3 KR- System components and interaction The the interactions between the KR ECU and the ID device ( remote key ) is performed in the two differ-
ent ways:
1. Normal mode: The unidirectional RF- communication uses the multi-band RF-Receiver IC TDA 5235 / Infineon. It is the user standard mode. 2. Emergency mode: The bidirectional LF- communication based on Transponder LF-Base station IC TMS3705A / ti. Mode is used in cases when the ID device battery is discharged. 3.1 Main system components:
S0 button controls different KR-ECU functions; see chapter 4 Project designation: Keyless Ride BMW Motorrad Project numbers: 0905.001 to 0905.004 HUF-authors: L.Patzelt /PDE-H, B.Mller /PDS-CA, D.Steegmann /PDS-PE, u. a.

It defines and match a legal user and activates / deactivates central lock-

ECU internal RF antenna Steering column bolt CAN interface 3.2 System Functionalities 3.2.1 Keyless Ride in far field communication A pressed button S0 placed on the KR-ECU causes switching on the external vehicle LF- antenna. A message is sent out via a LF-field up to an operating distance of 1m. When an ID device is matched in this range, it will be woken up. The ID deviceitself answers via the HF-filed by a message back to the KLR-ECU and the steering column is locked or unlocked as well as the ignition is switched ON/OFF. The HF-filed operates in a range up to 10 m. 3.2.2 Immobilizer deactivation option in near field communication In case that the wireless keys power supply is too low for HF-communication, it is possible to place the ID device directly on the LF- antenna ( distance ca. 3cm). After the button (S0) is pressed the ID device is supplied by the induction field of the LF- antenna directly, waked up and now able to answer backwards also via the adjacent LF- antenna.

The BMW KR ID device is used for transmitting the information for locking/unlocking the vehi-
cles central locking system and arm/disarm the anti-theft alarm system, respectively, via RF transmission for normal remote keyless entry function by pushing a button. The typical telegram length is approx. 52 ms. It is repeated every 100 ms, until the button is released or the timeout is reached. Additionally, the ID device can be woken up via specific LF wake up telegrams from the vehicle and transmit the corresponding RF information for passive start back to the vehicle. The typical telegram length is approx. 18 ms In general the following functions are provided:
- send command for locking the vehicles central locking system
- send command for unlocking the vehicles central locking system
- send command for arming the anti-theft alarm system
- send command for disarming the anti-theft alarm system
- send command for passive start of the engine (via LF wake up) For emergency start, in case the battery power of the ID device is too low, the BMW KR ID de-
vice has a bi-directional LF transponder interface. 10.3 Power supply The BMW KR ID device is provided with one lithium battery (coin cell, CR2032), which has a nominal voltage of +3 V.
