Internet of Vehicles Car T-BOX System Solution_Automotive TBOX Embedded ARM Application-Feiling Embedded

The Internet of Vehicles is one of the important branches of intelligent transportation and a typical application of the Internet of Things in the automotive industry and transportation system. In a broad sense, it belongs to the Internet of Things, a national emerging strategic industry. The Internet of Vehicles technology is one of the main technologies for future automobiles, along with new energy vehicles, autonomous driving, and lightweight. The Internet of Vehicles has now become an important integration promotion and demonstration application platform in my country's Internet of Things industry planning.

The Internet of Vehicles system consists of four parts: host, vehicle-mounted T-BOX, mobile phone APP and background system. The host is mainly used for audio and video entertainment and vehicle information display; the vehicle-mounted T-BOX is mainly used to communicate with the background system/mobile phone APP to realize the vehicle information display and control of the mobile phone APP.

Introduction to Car T-BOX

Telematics (telematics processing) BOX, referred to as vehicle-mounted T-BOX.

When the user sends a control command through the mobile APP, the background will send a monitoring request instruction to the on-board T-box. After the vehicle obtains the control command, it sends a control message through the CAN bus and realizes control of the vehicle. Finally, the operation result is fed back to the user's mobile APP. This function alone can help users remotely start the vehicle, turn on the air conditioner, adjust the seat to the appropriate position, etc.

Car T-BOX Product Application

■Personal car networking: remote control, anti-theft alarm, maintenance reminder, etc.

■ Car rental/car sharing: positioning, billing, operation management, etc.

■ Financial risk control: mortgage vehicle positioning, remote control, etc.

■ Bus management: positioning, maintenance reminders, anti-theft alarms, vehicle management, etc.

In-vehicle T-BOX main control module technical architecture and recommended design solutions

The vehicle-mounted T-BOX main control module adopts the Feiling embedded FETMX6UL-C core board, based on the NXP iMX6UL main chip, running the Linux operating system, and can achieve TCP/IP support for 4G networking.

The encryption chip is connected through IIC to ensure data security and communication security. It supports GPS and gravity sensors for vehicle positioning, posture and vibration recognition. It supports dual CAN buses and WIFI AP to provide network access support for other devices on the vehicle.

Car T-BOX functions

The on-board T-BOX can deeply read the car's Can bus data and private protocols, collect the bus data related to the car bus Kcan and PTcan and the private protocol reverse control respectively, and transmit the data to the cloud server through the 4G network, providing vehicle condition reports, driving reports, fuel consumption statistics, fault reminders, violation inquiries, location trajectories, driving behavior, security and anti-theft, appointment services, remote car search, and use mobile phones to control car doors, windows, lights, locks, horns, double flashes, mirror folding, sunroofs, monitor central control warnings and airbag status, etc.
