Correct ignition spark angle is important to enhance the dynamic performance and economy, reduce exhaust emission for electronic-control gasoline engine. Ignition Spark Angle is affected by many factors and characterized with dispersivity, nonlinear and uncertainty. Based on electronic-control engine pedestal experiments, this article tried to obtain the ignition spark angles by back propagation neural...
In this paper, the night long-distance bus drivers were the study object, an integrated test system with long time real-time continuous acquisition of ECG characteristics of drivers, traffic parameters of vehicles and road environment image acquisition were designed.
Based on data generated from four national standard tests of the constant speed condition, a set of vehicle system models is identified by subspace method for frequency domain characteristics analysis of vehicle system in full speed range. Both identification algorithm and model structure are validated. Based on the analysis results, steady state gains of all outputs as a function of vehicle speed...
For the safety issues of night long-distance bus drivers, a test system that real-time continuously acquires vehicles driving parameter, traffic environmental images as well as ECG physiological state of drivers under night-time driving conditions is designed. The impact of continuous driving time, night-time conditions and others on the driver's heart electrical parameters and driving behaviors is...
