| 摘 要： | 从采用一般换档规律的AMT车辆在坡道行驶时容易出现的问题出发,分析了换档循环、意外换档和紧急制动意外加速的原因；提出通过计算理论加速度判断坡道工况的方法；制定修正后的坡道综合控制换档规律.通过仿真分析,验证此方法可以有效解决各种坡道换档问题.

| Abstract: | Based on the problems appears when AMT vehicle with traditional shift rule is traveling in the ramp,the reasons of shift circulation,unexpected shift up and emergency brake with unexpected acceleration are analyzed.The method to determine the ramp condition from calculating theoretical acceleration is suggested.A comprehensive control shift strategy is established.By simulation analysis,effectiveness of this measure is verified. |
