The WMI is connected with a permanent 12V and the CAN bus, various control signals from the
CAN bus control the WMI and thus bring it into different working modes. In terms of driving
readiness, the WMI represents an interface between the head unit (Can with 250kBaud) and a
standard mobile phone from the driver of the vehicle. To support NFC telematics functions
including identification and data transmission to the vehicle head unit, for example for data
exchange with NFC vCards.

To support these functions, there is a coupling antenna in WMI that fulfills the following functions:
• Interface to the GSM mobile phone via the coupling antenna
• Interface to the NFC enabled mobile phone via the internal NFC antenna
• Interface to the vehicle antenna via the GSM plug connection
2.4.9 NFC vs. Charging
While entering the vehicle and putting down the mobile on to the WMI the mobile will initiate to
the WMI (start of system), while transferring some CAN commands from the car to the WMI.
During the misalignment of the NFC-antenna, no specific NFC-Commands will be send.
Once activated, the WMI tries to detect any device, if an object was placed on the surface. After
a succesful detection of a Qi device, the system switch to Qi-detection-mode.
If the detection-mode has found a mobile with Qi-standard charging possibility on the WMI, the
power contract is established and a charging process will start. If the mobile is removed during
charging from the WMI, charging process is stopped immediately.
The WMI was designed following the Qi standard to charge mobiles prepared for Qicharging. Current versions of the WMI do not fulfill the whole Qi-standard, therefore no Qi Logo
is declared on the WMI and no Qi-certification exists.

2.8 OPERATING MODES
The system controller of the SBC manages register configuration and controls the internal functions. The system
controller is a state machine. The SBC operating modes and the state transitions are shown in Figure 2.8-1. A
detailed hardware characterization of the SBC operating modes by functional block is listed in the following Table
2.8-1
[1.] Determined by the setting of bits V2C in the regulator control register
[2.] HVIO availability depends on the device variant
[3.] Determined by the settings in the relevant HVIO control register
[4.] See data sheet of the UJA1131HW/3V3, Determined by the settings in the SMPS control register
[5.] Determined by the setting of bits CMC in the CAN control register
[6.] Availability of LIN2 depends on the device variant
[7.] Determined by the setting of bits LMCn in the LIN control register
[8.] Determined by the settings of bits ENC and ENDC in the fail-safe control register
[9.] Since V1 is off, EN can only operate as open-drain output in Sleep mode
[10.] Determined by the setting of bit LHC in the Fail-safe control register
[11.] Determined by the setting of bits WMC in the Watchdog control register

2.9 OPERATIONAL MODES DEVICE DETECTION – QI
After putting the mobile on the WMI surface, the WMI will start up exchanging some CAN commands
from the car .
After initial start the WMI tries to detect via NFC, if an object was placed on the surface
(at this time the process does not send out NFC-Commands)
When the device detection was successful, the system switch to Qi-detection-mode. If the Qi-detectionmode has found a mobile (acc. Qi-standard) then charging process will start. The WMI was designed
following the Qi standard to charge mobiles prepared for Qi-charging. Because the WMI2 does not fulfill
the whole Qi-standard, therefore no Qi Logo is placed on the WMI and no Qi-certification has been
processed.
If you remove the mobile during charging from the WMI, charging process is stopped immediately.
