Abstract

The invention discloses an automobile control system software upgrading system and method. The method comprises the steps that an OTA server stores software upgrading packages of a vehicle-mounted CANcontroller and a vehicle-mounted Ethernet controller, and a remote information processor downloads the software upgrading packages of the vehicle-mounted CAN controller and the vehicle-mounted Ethernet controller from the OTA server; the central safety gateway performs integrity verification on the software upgrade packages of the vehicle-mounted CAN controller and the vehicle-mounted Ethernet controller, and sends the software upgrade packages of the CAN controller to the vehicle-mounted CAN controller for software upgrade; sending the software upgrading packet of the vehicle-mounted Ethernet controller to the vehicle-mounted Ethernet controller through the Ethernet for software upgrading; the vehicle-mounted CAN controller carries out firmware upgrading on the vehicle-mounted CAN controller according to the vehicle-mounted CAN controller firmware information table and by utilizing the firmware flashing task table; the upgrading efficiency of the automobile control system software can be improved, and the development period of the automobile control system software is shortened.

Description

Technical field [0001] The invention belongs to the technical field of automotive electronic systems, and specifically relates to an automotive control system software upgrade system and method. [0002] technical background [0003] With the information interaction between smart devices and smart cars, as well as the integration of multiple data sources in the Internet of Vehicles, the complexity of on-board functions and the personalization of human-computer interaction have been improved, which makes the car control system software update frequently. At present, the process of updating and upgrading automobile control system software still adopts the offline upgrade method of 4S stores. This traditional upgrade method is inefficient and has poor customer experience. Summary of the invention [0004] The purpose of the present invention is to provide an automobile control system software upgrade system and method in view of the above technical problems, which can improve the upgra...
