Abstract

The invention relates to an Internet-of-Vehicles terminal supporting the upgrade of other ECUs (Electronic Control Unit) by FOTA (Firmware Over-The-Air) and an implementation method. The Internet-of-Vehicles terminal includes an Internet-of-Vehicles platform, a vehicle-mounted TBOX terminal and an ECU component; the Internet-of-Vehicles platform is built by an Internet-of-Vehicles platform serverthat a vehicle factory is responsible for, and can communicate with the vehicle-mounted TBOX terminal through a communication network; and the vehicle-mounted TBOX terminal communicates with the ECU component through a high-speed USB and is used for reading the information of a vehicle and controlling some functions of the vehicle. According to the Internet-of-Vehicles terminal of the invention, the ECU component is upgraded through the FOTA, so it can be ensured that an automobile product meets customer demand and market change in time; the risk of software vulnerabilities can be lowered; information security protection capabilities can be enhanced; emergencies can be responded; the vulnerabilities can be fixed; and a mode in which customers are served and malfunctioned parts are returnedto factories through 4S stores can be changed, and therefore, service costs and recall costs can be reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to an Internet of Vehicles terminal supporting FOTA upgrade of other ECUs and an implementation method. Background technique [0002] In recent years, with the development of Internet of Vehicles technology, automobiles have gradually evolved from mechanical products to electronic products. Every system of a car, from wipers to navigation, from active safety to advanced driver assistance systems, is all realized with the help of various sophisticated and reliable electronic systems. As one of the core components of automobiles, ECU (Electronic Control Unit) electronic control unit has a higher and higher proportion in the total control components of automobiles. The number and complexity of the corresponding automotive software systems are also increasing, and the instability of the software is inevitable due to insufficient consideration and incomplete testing by ...
