为解决不同试验条件下汽车滑行阻力数据获取的问题，对美国法规SAE J1263中用于修正常温、常压下汽车滑行阻力的方法进行了适当修改，使其可将车辆在零海拔和20℃条件下的滑行阻力修正到不同海拔高度和温度条件下。对3辆试验样车进行了不同海拔高度和温度条件下的滑行试验，通过对比车辆的实测阻力和修正阻力验证了该修正方法的准确性和适应性。

To obtain vehicle coastdown resistance data at different test conditions, we modify appropriately the methods which revise vehicle coastdown resistance at nominal temperature and nominal pressure in US regulation SAEJ1263, then the method can be used to modify the vehicle coastdown resistance at altitude of 0 m and temperature of 20 ℃ to that at various altitudes and temperatures. Coastdown tests are carried out for three vehicles at different altitudes and temperatures, finally we compare measured resistance of the test vehicle and revised resistance, which verify accuracy and adaptability of this revision method.
