TELEMATICS SYSTEM : System Description

• The Telematics system provides information and service that can support secure and comfortable use of vehicles by a full-time link between the vehicle and user through the Nissan CARWINGS Data Center.
• Available service functions of the Telematics system is CARWINGS service function.
• TCU has a built-in wireless communication terminal and sends/receives data with the Nissan CARWINGS

  Data Center via TEL antenna using packet communication ^*1 and SMS ^*2 .

  NOTE:

  • *1: Packet communication is the communication method that sends/receives data in a small pack. Divided data is referred to as a packet and the communication line can be efficiently used.
  • *2: SMS stands for Short Message Service. It is also referred to as Text Messaging, Short Mail, etc. It is the service that performs text based message communication.
• The AV control unit and TCU are connected with the USB communication for sending/receiving operation signals and data signals.
• To use the Telematics system, it is necessary to activate TCU. The necessary conditions are as follows items.
  • Join the Telematics service.
  • Register the user ID and password in advance. (They are required for activation.)
  • For activation operation, refer to "ADDITIONAL SERVICE WHEN USING TELEMATICS SYSTEM (WORK STEP VIEW) : PROCESS CHART ".

COMMUNICATION SIGNAL

• TCU is connected to the AV control unit through USB communication (USB 1.0), and it sends/receives reception data of TCU and operation signals of the AV control unit.
• TCU is connected to VCM, HVBAT (Li-ion Battery) and OBC (On Board Charger) through EV CAN, and it sends/receives vehicle information.

CARWINGS SERVICE FUNCTION

The following services are provided for each situation.

Automatic Update of Charge Facility/Search for Nearest Charge Station

Automatic update of charge facility

• Nearby charge stations around the user's vehicle (area of within a radius of 25 km <15-1/2 miles> from the vehicle) are automatically updated when the low battery warning lamp turns ON.
• Neighborhood charge stations around user's house (area within approximately 160 km < approx. 100 miles >) are automatically updated periodically.

Search for nearest charge station

• If the battery capacity is low during driving, a charge warning is given in 3 steps. If the user follows the warning, data is sent/received to/from the Nissan CARWINGS Data Center. Charge facilities around the vehicle are searched, and guidance is started on the navigation system. The search location is memorized on the AV control unit as charge station information.
• When the user selects update of the charge facilities in the area, data is sent and received to/from the Nissan CARWINGS Data Center. Charge facilities around the area are searched, and the locations searched are memorized to the AV control unit as charge station information.
  NOTE: Up to about 1,000 charge stations can be memorized.

Information channel/probe information

• Start the navigation menu or power switch with external signals and perform data communication with the Nissan CARWINGS Data Center through TCU.
• Information channel obtains various kinds of information such as internet content prepared by the Nissan CARWINGS Data Center and provides voice guidance and display guidance.
• For voice sound used in the information channel, TCU receives the text data from the Nissan CARWINGS Data Center through the TEL antenna in packet communication and sends it to the AV control unit. The AV control unit converts the text data to voice signal and outputs to the front speaker.
• If CARWINGS reading voice is output while the audio is ON and/or the voice guidance is being output, these audio sounds are muted and only the CARWINGS reading voice is output.
• Various vehicle information data (battery condition, driving distance, warning display, etc.) is sent to the Nissan CARWINGS Data Center to store the data. The timing for transmission is the information channel and ECO drive connection.
