制动工况下机械式自动变速箱车辆换挡规律研究

The Study about Gear Shift Rules for Mechanical Automatic Transmission Vehicles on Braking Condition

从采用一般换挡规律的AMT车辆在制动工况下容易出现的问题出发,分析了意外换挡和紧急制动意外加速的原因;按制动强度不同制定了中强度、高强度制动控制换挡规律。通过仿真分析,验证此方法可以有效解决制动工况的换挡问题。

Based on the problems what appears when AMT vehicle with traditional shift rule is traveling in brake conditions, this paper analyzed the reasons of unexpected shift up and emergency brake with unexpected acceleration, established shift rules about high strength braking condition and middle strength braking condition, established a comprehensive control shift strategy. By simulation analysis, effectiveness of this measure is verified.
