T-BOX

The Internet of Vehicles has become the development trend of the automobile industry, and the penetration rate of the Internet of Vehicles is constantly increasing. The foreseeable market size is huge. Tbox, the full name of Telematics Box, provides functions such as external network connection, location service, local diagnosis and remote diagnosis. At the same time, we have also seen that the functions of TBOX are becoming more and more powerful. The loading of 4G/5G, V2X and other units, the connection between vehicles, the connection between vehicles and roadside equipment (RSU), and the connection between vehicles and pedestrians can be achieved. Realization, the connection between vehicles and network infrastructure, intelligent network connection and vehicle-road collaboration are gradually coming to the fore.

Arrow foresees the needs of the market, so it cooperates with NXP, Molex, Vishay, etc. to create and launch the TBOX + V2X application reference design solution and related hardware and software supporting services, in order to help customers quickly realize intelligent networking and vehicle-road collaboration products.

Arrow TBOX + V2X Application Reference Design Solution

The Arrow TBOX + V2X application reference design solution Demo board is divided into 3 parts. The advantage of being divided into 3 parts is that it is convenient for customers to configure and test flexibly under the cutting function.

1. The base board, including the MCU system, and the communication part. It realizes PMU, CAN, Secure boot, supports communication with V2X, antenna open circuit detection, data transmission and other functions, which satisfies the information acquisition and interaction of vehicles. The MCU system uses NXP S32K144.

2. NXP I.MX8 core board, running V2X core protocol stack (such as V2V, V2I, V2N, V2P) and Linux system and related AG15 drivers.

3. WIFI & BT board

NXP S32K144 belongs to the 32-bit Arm Cortex automotive MCU S32K1 series. The advantages of this series are:

* The S32K1 microcontroller has a hardware security subsystem with NXP firmware that supports firmware over-the-air (FOTA).

* Arm® Cortex®-M family based hardware and software scalable compatible, low-power microcontroller with advanced functional safety, information security and software support for automotive electronics applications

* Product long-term supply plan commitment: at least 15 years of product long-term supply plan support

* Engineering Support: Comprehensive third-party software and tools ecosystem support. A strong support team and technical Q&A in the online engineering community are the guarantee for faster design cycles

Arrow TBOX + V2X Application Reference Design Solution Hardware Architecture

Advantages of Arrow TBOX + V2X Application Reference Design Solution

In the pre-research stage, Arrow TBOX + V2X application reference design solution has fully investigated the needs and pain points of the market, and selected a competitive platform solution in the industry. The advantages of our reference design solution are:

1. Mature V2X protocol stack, low latency, long distance, providing secure encryption algorithm. From the perspective of customers, we have launched two versions, one is the license version and the other is the free version. The free version facilitates the initial entry and evaluation of customers, and lowers the threshold for customer development. The license version is for commercial use.

2. The construction of the software testing platform can be based on the free V2X protocol stack software package and the Arrow reference design hardware platform + cloud platform, and the application layer scenario testing software can be built relatively quickly. Of course, Arrow has also set up several application scenarios for customers' reference and testing.

3. Tested and verified mainstream tailorable hardware platforms

Arrow can provide support

In order to support the rapid evaluation, testing and implementation of the TBOX + V2X application reference design solution on the client side, Arrow can provide the following resources and support services:

* Refer to the schematic diagram

* Demo board available for customer evaluation testing

* PCB reference layout, and assist customers to check

* In terms of software, the main control MCU part can provide the source code of the reference design, the driver and application layer code of the MCU, and the 4G part can provide the software development kit SDK, FOTA, EMMC management of the 4G module main platform Qualcomm 9X07, and peripherals drive etc. V2X part, V2X protocol library (license required), demo application code, V2X test cloud platform service.
