摘　　要：汽车动力性主要由最高车速、加速时间、最大爬坡度三个指标来评价。汽车动力性试验主要包括最高车速、起步连续换挡加速与超车加速和汽车最大爬坡度三大内容。上述试验项目需要特定的试验路段,且耗时较长。基于MATLAB编程可以绘出发动机外特性曲线图和动力特性图,从动力特性图的角度研究汽车的动力性,不仅可以准确获得最高车速、加速时间和最大爬坡度等指标,还可以通过图像观察相关变化趋势,为进一步研究汽车的动力性提供了参考。Vehicle dynamics mainly by the highest speed,acceleration time,the maximum climbing three indicators toevaluate.Vehicle power test includes the maximum speed,starting continuous shift acceleration and overtakingacceleration and the maximum car climbing three content.The pilot project requires a specific test section,and take a longtime.Based on the MATLAB programming,we can plot the engine characteristic curve and the dynamic characteristicdiagram.From the view of the dynamic characteristic diagram,we can study the dynamic performance of the vehicle,notonly can get the maximum vehicle speed,acceleration time and maximum climbing index,but also observe the correlationAnd provides a reference for further research on the dynamics of the vehicle.
