汽车加速时间修正方法研究

Research on Correction Method of Automobile Acceleration Time

针对目前国内汽车公司所采用的汽车加速性能试验方法现状,考虑到试验环境对加速时间的影响,提出了一套将试验环境因素进行修正到基准状态下的加速性能试验方法。为此设计了三种试验状态,通过实车试验,对试验结果进行修正对比分析,该试验方法能够有效的将三种不同试验环境下试验结果修正到基准状态下,且在基准状态下结果差异仅0.05s,为车辆加速性能测试提供了一种新的评价方法和测试方法。

In view of the present situation of automotive acceleration performance test methods adopted by domestic automobile companies.Taking into the impact of the test environment on the acceleration time,a set of accelerated performance test methods for correcting the test environmental factors to the base state is proposed.For the purpose,three test conditions were designed,and the real vehicle test was carried out.Through the comparative analysis and correction of the test results,the test method can effectively correct the test results in three different test conditions to the base state,and the difference of results is only 0.05 s in the base state.It provides a new evaluation method and test method for vehicle acceleration performance test.
