摘要

摘要: 对扭矩辅助型机械自动变速箱(AMT)有动力升挡控制策略进行研究。在商用车传统的AMT上,增加了一套由辅助离合器和自动控制装置组成的扭矩辅助机构。搭建了扭矩辅助型AMT的动力学模型。结合换挡评价指标,制定了扭矩辅助型AMT有动力升挡控制策略,基于2挡升3挡工况进行仿真研究,并通过整车试验验证该控制策略的有效性。仿真和试验结果表明,扭矩辅助型AMT能够在换档时输出动力,改善了换档品质。

Abstract: The power upshift control strategy of torque-assist automated mechanical transmission (AMT) is researched. A torque-assist mechanism is equipped in the traditional AMT of commercial vehicle, which is made up of an assist clutch and automated control unit. The dynamic model of torque-assist AMT is established. According to the evaluation criterion of the shift process, the power upshift control strategy is developed. The simulation research is carried out based on the state from the second gear to the third gear, and the vehicle test is taken to verify the validity of the control strategy. The simulation and test results show that the torque-assist AMT can output power during the shift process and improve the shift quality.
