The invention provides an electric control diagnosis method and diagnosis system for faults of key parts of an automobile clutch system and an automobile, and belongs to the technical field of automobile clutch systems. Calculating the current power consumption required by the vehicle based on the obtained vehicle driving stage; analyzing the power output by the engine and the change state of the vehicle dynamic property after the driver steps on the accelerator pedal; if the difference between the power consumption of the vehicle power increase in the starting stage and the power output by the engine is within the preset power threshold difference, the vehicle power is normal and does not decline; if the power output by the engine is greater than the power consumption required by the vehicle power lifting, the vehicle power declines; and if the vehicle power recession state occurs and the output of the vehicle clutch system has a failure fault, an alarm prompt is given out. According to the method, whether related parts of the clutch can work normally or not can be actively judged on line in real time, a prompt is given out in time if a fault occurs, and the safety of a vehicle is improved.

    本发明提供一种汽车离合系统关键零部件故障的电控诊断方法、诊断系统及车辆,属于汽车离合系统技术领域,基于车辆操作状态,判断车辆的行驶阶段;基于得到的车辆行驶阶段,计算车辆当前所需的功耗;分析驾驶员踩油门踏板后,发动机输出的功率与车辆动力性的变化状态;如果起步阶段车辆动力提升的功耗和发动机输出的功率之差在预设功率阈值差之内,则车辆动力性正常,无衰退;如果发动机输出的功率大于车辆动力提升所需的功耗,则表示车辆动力衰退;如果出现车辆动力衰退状态,且车辆离合系统输出出现失效故障,则发出报警提示。本发明可以在线实时主动判断出离合器相关部件是否可以正常工作,如出现故障则及时发出提示,提高车辆的安全性。
