The invention discloses a dual-motor hybrid system clutch fault determination method, a vehicle, a computer readable storage medium and a computer program product. The method comprises the steps that target current meeting a preset condition is sent to an electromagnetic valve; if at least one of the conditions that the current and the duration fed back by the electromagnetic valve are matched with the first set of preset values and the speed difference and the duration of the driving disc and the driven disc of the clutch are matched with the second set of preset values is met, the fault of the clutch is determined to be an unable-to-open fault; and if at least one condition that the current and the duration fed back by the electromagnetic valve are matched with the third group of preset values and the speed difference and the duration of the driving disc and the driven disc of the clutch are matched with the fourth group of preset values is met, determining that the fault of the clutch is an unable-to-combine fault. According to the embodiment of the invention, the current state of the clutch is comprehensively judged through factors such as the target current sent to the electromagnetic valve, the current magnitude and duration fed back by the electromagnetic valve, the rotating speed and duration of the driving and driven discs of the clutch and the like, and the fault state of the clutch is quickly identified.

    本发明公开了一种双电机混动系统离合器故障确定方法、车辆、计算机可读存储介质及计算机程序产品。该方法包括:向电磁阀发送满足预设条件的目标电流;如果电磁阀反馈的电流和持续时间匹配第一组预设值、离合器主从动盘的速差和持续时间匹配第二组预设值中至少一个条件满足,则确定离合器的故障为无法打开故障;如果电磁阀反馈的电流和持续时间匹配第三组预设值、离合器主从动盘的速差和持续时间匹配第四组预设值中至少一个条件满足,则确定离合器的故障为无法结合故障。本发明实施例通过向电磁阀发送的目标电流与电磁阀反馈的电流大小和持续时间、离合器主从动盘转速和持续时间等因素综合判断当前离合器的状态,实现了快速识别离合器的故障状态。
