Using software testing data collected, this paper established a software safety defects S curve model based on Weibull model theory. χ2 testing and prediction error testing are employed to verify the matching ability of the Weibull model and applicability of the predicting result. How to select truncation error is also discussed here. Results show that better predictive effect can be achieved...
For the purpose of engineering development for failure insert testing, a HiL model for automatic transmission was established and key boards of dSPACE system which contributed testing were set up. Aimed to simulate solenoid and sensor failure insert testing, the testing theory and method were introduced. Testing results showed that failure insert testing method can be used for solenoid and sensor...
