摘　　要：简要介绍了汽车跑偏量的现有测试方法及其不足,提出运用GPS技术进行跑偏量的测试。在引用GPS测试中有关公式的基础上,推导出基于GPS的汽车跑偏量的计算方法。对某一车辆实际测试和计算的结果表明,采用GPS技术测量跑偏的方法简单、便捷,能达到相当高的测试精度。The existing measurement methods of vehicle driving deviation are briefly presented with their defects pointed out, and the GPS technology is proposed to be used for deviation measurement. Based on the related formulae in GPS measurement cited, a GPS-based vehicle driving deviation calculation method is derived. The resuits of the measurement and calculation for a real vehicle indicate that the GPS-based measurement method for vehicle driving deviation is simple and convenient with a rather high measurement accuracy achieved.
