Abstract

The present invention relates to the technical field of automatic driving, and provides a method and device for processing delay in control of an automatic driving vehicle, wherein the method includes: monitoring whether a thread in a preset function node has a delay, wherein the thread has a preset priority range; if the current If there is a delay in the thread and the current thread is the first priority, then adjust the priority to the second priority higher than the first priority; if the current thread is delayed and the current thread is the third priority, then it is judged When binding to the corresponding processor core, bind the current thread to the corresponding processor core, wherein the third priority is the maximum value within the preset priority range of the current thread. It is used to solve the defect of increasing the processing speed and computing power by increasing the number of processors, and realize the rational use of processor resources without increasing the number of processors, enhance the data processing speed and improve the The effect of computing power.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a control delay processing method and device for an automatic driving vehicle. Background technique [0002] The automatic driving control system is a complex control system that involves modules such as high-precision maps, perception, decision-making, planning, and control. The operation of this system requires a processor with fast data processing and computing capabilities. [0003] When the processing speed or processing power of the processor of the self-driving vehicle is insufficient, it will cause the program to run blocked and freeze, and when the program is blocked or stuck, the control of the self-driving vehicle will fail, which will affect the safety of automatic driving. [0004] In the prior art, increasing the number of processors is often used to increase the number of processors in order to increase the processing speed and increase the comput...
