The invention discloses an electronic oil pump failure processing method and a device for a power automobile. The method comprises the steps of receiving a fault notification message from an electronic oil pump controller, and the fault notification message is used for indicating that the electronic oil pump is in a failure state at present; determining to enter a gearbox electronic oil pump failure processing mode according to the failure notification message; and in the failure processing mode of the electronic oil pump of the gearbox, controlling the mechanical oil pump to cool and lubricate the gearbox according to the working state of the power automobile. The technical problems that in the related art, a gearbox needs an oil pump to provide lubrication and cooling, and when an electronic oil pump fails and cannot provide lubrication and cooling, normal work of the hybrid electric vehicle can be affected are solved.
本发明公开了一种动力汽车的电子油泵失效处理方法及装置。该方法包括:接收来自于电子油泵控制器的故障通知消息,其中,故障通知消息用于表示电子油泵当前处于失效状态;根据故障通知消息确定进入变速箱电子油泵失效处理模式;在变速箱电子油泵失效处理模式下,根据动力汽车的工作状态控制机械油泵对变速箱进行冷却和润滑处理。本发明解决了相关技术中变速箱需要油泵提供润滑和冷却,而当电子油泵失效无法提供润滑和冷却时,将会影响混合动力汽车的正常工作的技术问题。
