What is Telematics Control Unit

Telematics Control Unit (TCU) is an electronic device installed inside vehicles, featuring functions such as remote monitoring, vehicle positioning/navigation, safety features, and vehicle communication, enabling communication and data transmission with the external environment, enhancing the intelligence level of automobiles, and improving vehicle safety, convenience, and connectivity.

What is Telematics Control Unit

Telematics Control Unit A6 is recommended for new energy vehicles, integrating 3G/4G wireless communication, real-time GPS/BDS positioning, and CAN/OBD vehicle data diagnostic technology. It is specifically designed for modern intelligent networked vehicles. The terminal supports deep reading of vehicle CAN data, collection, storage, and transmission of vehicle data, analysis of engine emission status, and DTC fault data, suitable for diesel vehicles and new energy vehicles.


Telematics Control Unit A6 features:

- Large capacity memory: Built-in 8GB memory for collecting and storing engine CAN data.

- Rich CAN protocols: Compatible with international standard CAN protocols such as SAE J1939, ISO 15031, and ISO 27145.

- Universal communication: Supports 4G/3G/2G universal communication, GPS/BD dual-mode positioning.

- Standard OBD interface: Supports standard OBD interface, perfectly compatible with various vehicle models on the market.

- Electrical isolation: Supports CAN electrical isolation, vehicle CAN data transmission and reception do not affect ECU operation.

- Battery support: Supports backup battery, can continue to operate for more than 30 minutes after vehicle power-off.

- Rich expansion interfaces: Supports multiple serial ports (IO/RS485/RS232) for other application expansions.
