|
Certification ECU (Smart Key ECU Assembly)
|
Receives the remote engine start signal from the user's
smartphone or electrical key transmitter sub-assembly via the DCM (telematics
transceiver) and initiates the engine start operation.
|
Air Conditioning Amplifier Assembly
|
- Sends ambient temperature signals to the DCM (telematics transceiver).
- Operates the air conditioning system and/or rear defogger after
the engine has been started by remote operation, based on signals
from the DCM (telematics transceiver).
|
Main Body ECU (Multiplex Network Body ECU)
|

signal is received.
|
FUNCTION
(a) The main services of Remote Connect are as follows:

|
Remote Service
|
Function
|
Remote Information
|
Vehicle Status Report
|
Allows the vehicle status (doors open/closed, etc.) and
vehicle information (distance traveled, etc.) to be checked from a remote
location via a smartphone, after the ignition switch has been turned off.
By updating the information, the latest vehicle status can be displayed.*1
|
Remote Notification
|
Guest Driver Monitor
|
- Allows the user to set limits on the vehicle speed, traveling
time, etc. when a guest driver (a family member, valet, etc.) is
driving the vehicle, via a smartphone.
- If the guest driver exceeds a user set limit, a notification
will be sent to the user so the driving status can be monitored.*2,*3
|
Vehicle Status Alerts
|
Sends a notification to the user if certain operations
are not performed within a certain amount of time after the ignition switch
is turned off, such as locking the doors, closing the windows, etc.*2,*4
|
Remote Operation
|
Remote Engine Start and Stop
|
- Allows the user to start the engine and keep it operating for
a certain amount of time from a remote location via a smartphone
or the electrical key transmitter sub-assembly. The engine can also
be stopped remotely after being started by the remote operation.*5
- Starts the air conditioning system when the engine is remotely
started if the air conditioning system was on when the ignition
switch was last turned off.
- The air conditioning system or rear defogger may be operated
by signals from the service center depending on the ambient temperature.
|
Remote Door Lock and Unlock
|
Allows the doors to be locked/unlocked from a remote location
via a smartphone.*6
|
- *1: If the latest vehicle information has not been sent from the vehicle
due to the condition of the vehicle (such as if the DCM [telematics transceiver]
is outside of the cellular telephone reception area), the most recently
received information will be displayed.
- *2: No notifications will be sent if the latest vehicle information
has not been sent from the vehicle due to the condition of the vehicle (such
as if the DCM [telematics transceiver] is outside of the cellular telephone
reception area). Notifications may be delayed if the smartphone has poor
reception.
- *3: Only one notification per set condition will be sent during a single
trip.
- *4: If the smart key system has been canceled, vehicle status alerts
notifications will not be sent to the user. If the electrical key transmitter
sub-assembly is inside the vehicle or detected as being "inside cabin",
vehicle status alerts notifications will not be sent.
- *5: If the vehicle cannot receive the remote engine start signal due
to the condition of the vehicle (such as if the DCM [telematics transceiver]
is outside of the cellular telephone reception area), the engine will not
be started remotely. Additionally, the remote engine stop operation signal
may not be received depending on vehicle conditions.
- *6: If the vehicle cannot receive a door lock/unlock signal due to the
condition of the vehicle (such as if the DCM [telematics transceiver] is
outside of the cellular telephone reception area), the door lock or unlock
operation will not be performed. After a door unlock operation is performed,
if the doors are not opened within a certain amount of time, the doors will
automatically be locked.
OUTLINE
(a) When a warning is generated due to a vehicle malfunction, the
DCM (telematics transceiver) receives warning information from the combination meter
assembly and sends a warning notification to the service center. The radio and display
receiver assembly also receives the warning information sent by the combination
meter assembly and displays a message in the multi-display according to the malfunction.

SERVICES FUNCTION
(a) Destination Assist Connect
- Downloads the user's desired destination information to the navigation
function after the call center is told the destination.
- Stores the information downloaded in the navigation function so the
information can be reused as required.
- Destination Assist Connect is an in-vehicle service that allows subscribers
to request directions to any location. Subscribers are connected to an agent
through the Destination Assist button and may ask the agent to download
the location of any destination to the navigation function in the vehicle.
Agents are able to locate specific Points Of Interest (POI's) by search
terms, locate specific addresses, or provide Zagat-rated restaurants as
premium POI's. Agents are able to search for POI's using the distance from
the vehicle, from a city, or from another POI. The navigation function can
store up to 5 POI's at a time, which can be added to the device queue as
the first or last entry, or as a replacement for all entries.
(b) Dynamic Voice Recognition
By performing the voice recognition process with the server, natural
talk input and other interactive voice operations besides the specified commands
can be performed. In addition, by storing all of the user's utterances, the server
will learn, and be able to perform voice recognition with greater accuracy.
