Analysis on Speed Validation of the Driving Simulator Based on Different Plane Alignment

通过分析国内外经典速度预测模型,在此基础上选择目前国内外广泛应用的经典速度预测模型即Lamm模型作为标准,然后设计了驾驶模拟器速度有效性验证的标准实验场,通过选定的经典速度预测模型,计算得到标准实验场的预测车速,提出了车速有效性验证的方法,即将标准实验场的预测车速与模拟实验车速进行对比分析,将其作为驾驶模拟器实验车速的绝对有效性和相对有效性评价方法,为驾驶模拟器速度有效性的验证提供规范的验证标准。并使用昆明理工大学中型研究型驾驶模拟器进行模拟器速度有效性验证标准的应用研究。通过对比分析标准实验场的预测车速轨迹曲线与实验车速轨迹曲线,从两种车速的显著性差异和两种变化趋势等方面对该中型模拟器进行了验证。

Through analysis of classic speed forecasting models both at home and abroad, the widely used-Lamm model was chosen as a standard model. Then a standard experimental field was designed to validate the speed of the driving simulator. With the selected classic speed forecasting model, forecast speed of the stan- dard experimental field was calculated. In this paper, the method of speed validation was explored, which com- pared and analyzed the forecast speed of standard experimental field and the speed of the driving simulator, then the related results were used to evaluate the absolute validity and relative effectiveness of the driving simulator＇ s experimental speed, thus providing a validation criterion for driving simulator＇ s speed validation. The applica- tion research about the driving simulator＇ s speed validation standard was carried out in Kunming University of Science and Technology. The forecast speed trajectory curve and experimental speed trajectory curve of the stan- dard experimental field were compared and analyzed. Furthermore, the medium driving simulation system was verified by the differences of the two speeds and two changing trends.
