The invention relates to the technical field of engine gearbox early warning, and particularly discloses an engine gearbox early warning method and system and an intelligent networked automobile. The method comprises the following steps: acquiring a gear-shifting performance evaluation value, a gear-shifting impact evaluation value and a gear-shifting smoothness evaluation value of a gearbox at the current moment, further acquiring an early-warning judgment value of the gearbox at the current moment, and acquiring a monitoring judgment result of the gearbox at the current moment based on the early-warning judgment value of the gearbox at the current moment. And according to the monitoring judgment result of the engine and the gearbox at the current moment, an engine gearbox early warning result at the current moment is obtained. According to the method and the device, whether the running condition of the gearbox at the current moment needs to be pre-warned or not is accurately quantified, so that a more comprehensive and accurate engine gearbox pre-warning result is obtained, and potential fault problems of the gearbox and an engine can be found in time.

    本发明涉及发动机变速箱预警技术领域,并具体公开了一种发动机变速箱预警方法、系统及智能网联汽车,包括:基于变速箱在当前时刻前预设时间段内所有换档时刻的所有换档监测信息,获得变速箱在当前时刻的入档性能评估值、换挡冲击评估值及换挡平顺性评估值,进而获得变速箱在当前时刻的预警判断值,并基于变速箱在当前时刻的预警判断值,获得变速箱在当前时刻的监测判断结果,进而根据发动机和变速箱在当前时刻的监测判断结果,获得当前时刻的发动机变速箱预警结果。本发明实现了对变速箱在当前时刻的运行情况是否需进行预警进行精确量化,进而实现了获取更加全面、准确的发动机变速箱预警结果,以便及时发现变速箱及发动机潜在的故障问题。
