摘要 对于装有自动变速器的车辆,为避免在坡道上不必要的换挡,我们研究了两种计算道路坡度的算法。一种算法是使用一个纵向加速度传感器,而另一种是采用车辆的输出转矩来计算。通过试验分析比较,发现后一种算法更为实用。 For vehicles with automatic transmissions,two methods for road slope estimation algorithm were presented to avoid needless shifting on slope road. One algorithms makes an estimation using a longitudinal acceleration sensor and the other using vehicle output torque.The former is thought to be more accurate on estimating road slope than the latter, but the former is more expensive because an additional acceleration sensor. By experimental analysis, we found that the latter could estimate road slope accurately enough to avoid needless shifting.
