The invention discloses a vehicle cooling liquid filling mode fault diagnosis method and device, and the method comprises the steps: obtaining a starting signal of a cooling liquid filling mode through recognizing a cooling liquid filling mode entering condition; according to the starting signal, all cooling parts of the cooling system are controlled to operate according to preset operation parameters; the real-time operation parameters of all the cooling parts are compared with preset operation parameters; and if the real-time operation parameters of all the cooling parts are the same as the preset operation parameters, cooling liquid filling is carried out, otherwise, faults of all the cooling parts of the cooling system are recognized, and corresponding fault state signals are output. By means of the method, actions of operators can be simplified, filling failure caused by insufficient capacity of the operators is prevented, fault reasons can be rapidly positioned after filling failure, and the filling efficiency is improved.

    本发明公开了一种车辆冷却液加注模式故障诊断方法及装置,包括:通过识别冷却液加注模式进入条件,得到冷却液加注模式的启动信号;根据启动信号,按照预设运行参数控制冷却系统的各个冷却部件运行;将各个冷却部件的实时运行参数与预设运行参数进行对比;如果各个冷却部件的实时运行参数与预设运行参数相同,则进行冷却液加注,否则识别冷却系统的各个冷却部件的故障,输出相应的故障状态信号。本发明能够简化操作人员的动作、防止由于操作人员能力不足导致加注失败,能够在加注失败后快速定位故障的原因、提升加注效率。
