The invention discloses a protection control device and a protection control method of a wet-type gear shifting clutch. Whether an overheating protection measure is started or not is determined by using two judgment conditions of a surface temperature of an engaging clutch and gear shifting duration time under a rotating speed phase; and ablation caused by instantaneous overheating due to violentsliding friction of the surface temperature of the engaging clutch can be avoided, excessive abrasion caused by too long sliding friction time of the engaging clutch can also be avoided, and comprehensive protection and prolonging of the service lives of the clutch and a transmission are facilitated. Four working conditions can be separated from the two judgment conditions of the surface temperature of the engaging clutch and the gear shifting duration time under the rotating speed phase, control measures of different degrees are adopted respectively, and on the basis that the service life ofthe clutch and the service life of the transmission are protected, riding comfort of drivers and passengers can be improved. A clutch control electromagnetic valve and an engine are controlled while control measures are taken, the clutch control electromagnetic valve and the engine are overlapped, and a control effect can be improved.

    本发明公开了一种湿式换挡离合器的保护控制装置及保护控制方法,使用接合离合器的表面温度与转速相下的换挡持续时间两种判断条件来确定是否启动过热保护措施,可以避免接合离合器表面温度因剧烈滑摩而瞬时过热导致的烧蚀,也可以避免接合离合器滑摩时间过长而造成的过度磨损,有利于全面保护延长离合器和变速器的使用寿命。从接合离合器的表面温度与转速相下的换挡持续时间两种判断条件出发,可以分离出四种工况,分别采用不同程度的控制措施,在达到保护离合器与变速器寿命的基础上,还可以提升驾乘人员乘坐的舒适性。在实行控制措施的同时对离合器控制电磁阀与发动机进行控制,两者相互叠加,可以提升控制效果。
