Embodiment Construction

[0060] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0061] The current electronic control system mostly uses the XCP / CPP protocol to simultaneously support data acquisition events with multiple time intervals, such as: 10ms, 50ms, 100ms, etc. Each data acquisition event supports data acquisition of multiple variables. A flowchart of a method for event configuration in the prior art, such as figure 1 S...

Abstract

The embodiment of the present application provides a method and device for event configuration, the method includes: if a data acquisition configuration instruction of a target event is received, then judging whether there is an event configured for data acquisition in the CAN bus except the target event; if If there is an event of the configured data acquisition, then according to the time taken by the data transmission corresponding to the event of the configured data acquisition, and the number of messages that can be sent by the CAN bus per unit time, it is determined that the CAN bus can be The number of messages configured for the target event; according to the number of messages that the CAN bus can configure for the target event and the number of messages that need to be configured for the target event, the target event is configured, wherein , the number of packets to be configured for the target event is determined according to the data collection configuration instruction. It can avoid the deviation of the time interval between the current packet data of the event and the previous packet data, and ensure the accuracy of the data collection time.

Description

technical field [0001] The embodiments of the present application relate to the technical field of automotive electronic control, and in particular to a method and device for event configuration. Background technique [0002] With the development of social economy and the continuous improvement of people's living standards, vehicles are becoming more and more popular and become an important means of transportation for people to travel. Vehicle electronic control technology has become an important symbol to measure the development level of modern automobiles. Vehicle electronic control systems play an important role in improving vehicle comfort, handling, and safety. By collecting events of the electronic control system of the vehicle, analyzing the data in the event, and troubleshooting or optimizing the vehicle according to the results of the data analysis. [0003] The current electronic control system mostly uses the XCP / CPP protocol to simultaneously support data acquis...
