Abstract

The invention discloses a technical scheme for remotely upgrading FOTA (Firmware Over-the-Air) firmware on a new energy automobile. At present, remote upgrading of multiple electronic units (ECUs) ofa new energy vehicle based on an intelligent terminal (T-BOX) is achieved. The remote upgrading system comprises a vehicle control unit (VCU), a battery management system (BMS), a motor controller (IPU) and a vehicle instrument (ICU). Meanwhile, in the uploading process of the upgrade package, privacy of a hardware softdog is guaranteed, manufacturing and local storage of the offline upgrade package are also included, and safety and stability of a whole vehicle system in the upgrading process are greatly guaranteed. A vehicle enterprise can achieve large-scale upgrading and repair of vehicle-mounted equipment software faults through the technology. The development risk and the recall cost are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile firmware maintenance, and in particular relates to a FOTA firmware remote upgrade system and method for a new energy automobile. Background technique [0002] In the automotive industry, with the trend of intelligent development, automobiles will become the third largest mobile terminal after smartphones and personal computers, gradually evolving from mechanical products to electronic products; in addition, the Internet of Vehicles technology is developing rapidly, and automotive software systems continue increase, and software instability is inevitable, therefore, the demand for FOTA firmware upgrades also arises as the times require. Every system of a car, from wipers to navigation, from active safety to advanced driver assistance systems (ADAS), is all realized with the help of various sophisticated and reliable electronic systems. According to statistics, more than 50% of the car recalls i...
