DESCRIPTION

  • NissanConnect Services provide various services to support dealing with emergencies of the subscribed Nissan Ariya vehicle and the driver. For example, in case of an illness or serious injury, you can seek support by pushing the in-Nissan Ariya vehicle telematics switch (SOS button) and connecting to the NissanConnect Services Response Center.

  • The NissanConnect Services Response Center can specify the location of the Nissan Ariya vehicle via GPS, and the information will be sent to the police or other agencies as needed.

  • Telematics Communication Unit (TCU) equipped with a radio communication terminal communicates with the NissanConnect Services Response Center via radio waves for receiving NissanConnect services.

  • With the equipment of the radio communication terminal, TCU communicates with NissanConnect Services Response Center by Packet communication*1 and SMS*2 via TEL antenna.

    NOTE:

    • *1: Packet communication means a communication method that data is broken down into smaller chunks for communication. The split data is called a packet and improves the efficiency of the communication circuit.

    • *2: SMS stands for Short Message Service, also known as text messaging or short mail, and provides text-based message communication services.

  • While communicating with the operator, data (e.g. transmission of own vehicle location) is transmitted to the NissanConnect Services Response Center by using DTMF tone signals and SMS via the radio communication module included in TCU.

  • Audio signals transmitted and received while communicating with the operator are input by microphone connected to TCU.

  • Audio signals are output from TCU via the audio data circuit connected to the AV control unit.

COMMUNICATION SIGNAL

  • TCU is connected to the AV control unit via USB communication, and it sends/receives reception data of TCU and operation signals of the AV control unit.

  • TCU is connected to each control unit via CAN communication, and it sends/receives Nissan Ariya vehicle information.
