Automatic driving vehicle control delay processing method and device

Abstract

The invention relates to the technical field of automatic driving, and provides an automatic driving vehicle control delay processing method and device, and the method comprises the steps: monitoring whether a thread in a preset function node is delayed or not, and the thread has a preset priority range; if the current thread is delayed and the current thread is the first priority, adjusting the priority to be a second priority which is greater than the first priority; if the current thread is delayed and the current thread has a third priority, when it is judged that the current thread is not bound to the corresponding processor core, the current thread is bound to the corresponding processor core, and the third priority is the maximum value within the preset priority range of the current thread. The method and the device are used for overcoming the defect that the cost is increased due to the fact that the processing speed is increased and the computing power is improved by increasing the number of processors, and achieving the effects of reasonably utilizing processor resources, increasing the data processing speed and improving the computing power on the premise that the number of the processors is not increased.

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...
