This invention relates to the fields of automotive electronics and in-vehicle network information security technology, and particularly to an automotive software scheduling method and system based on information security and dynamic programming, applied to an in-vehicle telematics controller (TBOX). The method includes the following steps: quantifying and defining multiple information security tasks to be scheduled; configuring execution time and information security weight for each information security task; the execution time being the completion time of the information security task on a specified hardware platform; and the information security weight being the contribution of the information security task to the overall vehicle information security protection level. This invention is the first to introduce information security weight as a core optimization objective into automotive task scheduling. Through a dynamic programming algorithm, it maximizes the total information security weight within a finite time, ensuring accurate allocation of security resources and improving the overall vehicle information security protection efficiency. Furthermore, the scheduling strategy possesses strong dynamic adaptability, capable of real-time replanning based on system security status, task set, and resource status, flexibly responding to network attack scenarios.

This invention discloses an OTA (Over-The-Air) upgrade method and related equipment for automobiles, including maintaining an upgrade database, determining the version upgrade packages corresponding to multiple upgrade cycles, retrieving the version upgrade package corresponding to any upgrade cycle from the upgrade database when the upgrade cycle arrives, and using the version upgrade package to upgrade the vehicle's infotainment system via OTA.
