Haitong Communication has launched a constantly improving and reliable in-vehicle T-BOX accessory solution in the fields of antennas, metal parts, communication interconnection interfaces, and plastic shells.
1. T-BOX What is the system?
TelematicsBOX, abbreviated as T-BOX, also known as Telematics Control Unit (TCU), is an intelligent terminal device composed of a processor, GPS module, 4G/5G module (with SIM card function), and various interfaces (such as CAN bus, USB, RS-232, Bluetooth, etc.). It is an important component of the Internet of Vehicles system. By connecting to the in-vehicle CAN bus and the external cloud platform, it realizes communication and data exchange between vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-network (V2N).
2. T-BOX Current Status of System Development
With the increasing proportion of vehicle networking and the growing communication needs of OTA, remote vehicle control, digital keys, and other functions, the market demand for automotive T-Boxes is further expanding. In terms of market value, the market size of passenger car T-Boxes in China in 2022 was approximately 5.03 billion yuan, and it is expected to reach around 10 billion yuan in 2027, with an average annual growth rate of 14.8% in the next five years.
T-BOX is a key component of intelligent connected vehicles. Therefore, the development trend of intelligent and connected passenger vehicles is the core driving factor for the development of the T-BOX industry. Haitong Communication Antennas, metal parts, communication interconnection interfaces, plastic casings Haitong Communication has launched a continuously improved and reliable in-vehicle T-BOX accessory solution in the T-BOX accessory fields such as antennas, metal parts, communication interconnection interfaces, and plastic casings.
3. Haitong's offerings T-BOX Accessory-related solutions
1 Antenna solutions
For T-BOX device antenna accessories, Haitong provides customized built-in antenna services according to customer needs.
Built-in antenna ： T-BOX devices can be designed with built-in antennas, meaning the antenna is directly integrated inside the T-BOX without the need for additional antenna installation. The advantages of Haitong Communication's built-in antennas are ease of installation and maintenance, and a cleaner appearance. Suitable for scenarios with low signal requirements and high appearance requirements.
External antenna ： T-BOX devices can also choose external antennas, meaning the antenna needs to be installed separately on the outside of the vehicle, usually connected to the T-BOX via an antenna cable. The advantages of Haitong's external antennas are more stable signal reception, as the antenna can be placed outside the vehicle, away from the interference of metal structures. In addition, by appropriately selecting the antenna's position and direction, the signal reception effect can be further optimized.
Haitong T-BOX Antenna testing environment
Antenna input characteristic testing uses Agilent E5071C vector network analyzer;
Antenna radiation characteristic testing uses Satimo SG24 3D near-field microwave anechoic chamber;
T-BOX physical object corresponding coordinates, active and passive anechoic chamber testing;
2、T-BOX Interface Interface solutions
T-BOX has various interfaces and buses, including not only the traditional Controller Area Network (CAN), Local Interconnect Network (LIN), and debugging interfaces RS232/RS485/USB2.0, but also the "new star" in-vehicle Ethernet.
Haitong Communication provides various types of interface designs, such as USB interfaces, RS232 interfaces, RS485 interfaces, antenna interfaces, and multi-PIN interfaces.
The interface solutions provided by Haitong Communication have the following characteristics: ：
- USB2.0 interface: Usually used for single-device connection, data is transmitted by inserting it into a computer or USB hub.
- RS232 interface: Commonly used for serial communication, suitable for short-distance communication, with high stability and reliability.
- RS485 interface: Commonly used for multi-device communication, with a longer communication distance and good anti-interference characteristics.
- Ethernet transceiver: Currently mainly used in non-CAN parts, interconnected with the gateway. Mainly solves the problems of high-speed data transmission, protocol compatibility, and cost constraints.
- LIN transceiver: Used in occasions with low speed and safety requirements, such as body electronic accessories (window lifting, etc.).
- CAN transceiver: High-speed CAN is mainly used in the control of power systems with high real-time requirements; low-speed CAN is mainly used in the control of comfort systems and body systems with lower real-time requirements.
3、T-BOX Metal parts solutions
In the field of T-BOX metal parts accessories, Haitong has more than 20 years of rich experience in "integrated manufacturing", integrating stamping and injection mold design and processing, precision machining, automated assembly, high-speed stamping, and injection molding, to provide customers with the most reasonable T-BOX metal parts accessory solutions.
Shielding cover ： Haitong Communication is one of the first providers and manufacturers of signal shielding device solutions in China. It can provide a variety of customizable solutions, such as ultra-lightweight, ultra-thin, square pads, and metal steel sheets.
Sheet metal parts ： Haitong Communication has numerous successful cases in sheet metal parts design and production, with accessories supplied to a large number of domestic automakers, such as SAIC and Geely.
Leaf spring ： Haitong has a product standard library of precision RF leaf springs and grounding leaf springs. The leaf springs designed and produced by Haitong have excellent qualities such as strong conductivity, anti-electromagnetic interference (EMI), and good weldability, and can be customized for customers according to actual needs.
4. T-BOX Plastic parts Housing solutions
Haitong Communication's T-BOX plastic housing fully considers the actual use environment, functional requirements, and appearance requirements of the product in terms of design. The material selection, structural design, and appearance design ensure that the plastic housing solution meets user expectations.
Haitong Communication has excellent production technology and can select appropriate production processes, such as injection molding or blow molding, according to the design and customer requirements, ensuring that the processing precision of the T-BOX plastic shell meets the design requirements and guaranteeing the appearance quality and service life.
Driven by strong policy support for the intelligent connected vehicle industry and the commercialization of 5G communication networks, China's intelligent connected vehicle industry faces enormous market opportunities. T-BOX will further integrate the advanced features of 5G, resulting in more powerful functionalities and significantly increased penetration rate and market size.
As a solution provider and manufacturer of T-BOX related accessories, Haitong Communication will continuously strive for progress, bringing readily available convenience to both automakers and users.
