A vehicle diagnostic method of a vehicle is disclosed. The vehicle includes an internal combustion engine and a continuously variable transmission operably coupled to the internal combustion engine. The method comprises the following steps: detecting a plurality of engine crankshaft acceleration change events; determining frequencies of the plurality of engine crankshaft acceleration change events; determining a continuously variable transmission belt interaction frequency of a drive belt of the continuously variable transmission; and classifying the plurality of engine crankshaft acceleration change events as one of an engine misfire event and a continuously variable transmission band damage event based on a comparison of the frequency and the continuously variable transmission band interaction frequency.
公开一种车辆的车辆诊断方法。所述车辆包括内燃发动机和可操作地联接到所述内燃发动机的无级变速器。所述方法包括以下步骤:检测多个发动机曲轴加速度变化事件;确定所述多个发动机曲轴加速度变化事件的频率;确定所述无级变速器的传动带的无级变速器带相互作用频率;以及基于所述频率与所述无级变速器带相互作用频率的比较,将所述多个发动机曲轴加速度变化事件归类为发动机失火事件和无级变速器带损坏事件中的一个。
