Abstract

The embodiment of the invention relates to a task scheduling method for automatic driving, and the method comprises the steps: obtaining a task set, and enabling a task to have a task function attribute label, a task type label and a triggering type label; classifying tasks in the task set for three times according to the task function attribute label, the task type label and the trigger type label to finally obtain a non-key task list, a driving task list, an automatic driving key task list, a time trigger type automatic driving key task list and an event trigger type automatic driving key task list; carrying out isolation partitioning on a logic processing core of the CPU, wherein each obtained partition is used for executing one type of task; and based on the classification list, adopting a corresponding scheduling strategy in each partition, and executing task scheduling on the task through a logic processing core.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an automatic driving-oriented task scheduling method. Background technique [0002] With the deep integration and rapid development of information technology and automobile manufacturing technology, technologies in the field of autonomous driving emerge in an endless stream, expanding the boundaries of algorithm capabilities and bringing about a great increase in software complexity. At present, existing software systems usually contain hundreds of task threads and dozens of task threads related to autonomous driving. These task threads have the characteristics of high computational complexity, large storage consumption, and frequent communication. If they cannot be reasonably restricted, they may This leads to vicious competition for computing resources between tasks, low system computing efficiency, high response delay, and even affects driving safety. [0003] In order t...
