摘　　要：离合器控制是机械式自动变速器控制的关键部分。离合器扭矩传递特性和温度变化存在一定的耦合关系,因此离合器的温度预估对离合器的传扭特性的研究具有重要影响。若离合器扭矩控制忽略温度的影响,导致对离合器的控制存在偏差,影响离合器的传扭特性。当离合器温度过高或过低时,应该采用相应措施对离合器进行保护。因此对干式离合器的温度预估具有重要的研究和工程实践意义。Clutch control is a key part of mechanical automatic transmission control. There is a certain coupling relationship between the clutch torque transmission characteristics and temperature changes, so the temperature estimation of the clutch has an important influence on the research on the torque transmission characteristics of the clutch. If the clutch torque control ignores the influence of temperature, the control of the clutch will be biased and the torque transmission characteristics of the clutch will be affected. When the clutch temperature is too high or too low, corresponding measures should be taken to protect the clutch. Therefore, the temperature prediction of dry clutch has important research and engineering practice significance.
