2.4.8 Connectors, external interfaces

The WMI is connected with a permanent 12V, the CAN bus and the Fakra blind, 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 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 successful detection of a Qi device, the system switches 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 Qi-charging.

4. 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 4-1. A detailed hardware characterization of the SBC operating modes by functional block is listed
in the following Table 4-1

[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

Via SPI2 interface the MWCT1014S is able to sent commands to the SBC so that the SBC can change
the operating mode. The operating mode is selected via bits MC in the Mode Control register, see Table
4-2.

SPI address of the Mode Control register: 0x01

4.1 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 WLC, if an object was placed on the surface
(at this time the process does not send out WLC-Commands)

When the device detection was successful, the system switch to Qi-detection-mode. If the Qi­detection-mode 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.

If you remove the mobile during charging from the WMI, charging process is stopped
immediately.
