Abstract

The invention relates to a software algorithm real-time reliability test platform and method based on historical working condition data. The test platform carries out test on an automobile ECU. The test platform comprises a main control board, a CAN hardware tool, a CANalyzer analysis test tool and a data display module, which are connected in sequence, wherein the CANalyzer analysis test tool is connected with a database and a data acquisition unit for obtaining real-time working condition data of operation of the whole vehicle. Through the working condition data collection tool, the real-time operation working condition data of an automobile is collected, recorded and stored; then, output data is converted into input data, and an output port is converted into an input port; ports needing hard line access are subjected to signal processing; the software is loaded to a test ECU, and the collected original ECU working condition data is played in real time and imported to the test ECU; and the two ECUs are same except the input and output, and thus the test platform is established. Therefore, real and complex working condition input is realized; and meanwhile, the ECU software algorithm is checked in real time, and reliability is enhanced.

Description

technical field [0001] The invention relates to the field of software reliability of electronic and computer application technology, in particular to a real-time reliability testing platform and method for software algorithms based on historical working condition data. Background technique [0002] With the continuous improvement of people's requirements for automobile safety, environmental protection, comfort, and entertainment, automobile electronic technology has continuously made new breakthroughs in functional diversification, system integration, volume miniaturization, and system networking. What comes is that the requirements for the reliability of the automotive ECU software algorithm are getting higher and higher, and the operating condition of the car is a random process, which is affected by many factors, such as road conditions, traffic flow, weather conditions, and changes in the technical performance of the car itself. . Therefore, it is discrete, nonlinear an...
