In various embodiments, methods, systems, and vehicles are provided for determining a fault in a suspension system of a vehicle. In an exemplary embodiment, sensor data is obtained via one or more vehicle sensors during operation of the vehicle; a one or more first coefficients for the vehicle are calculated via a processor using a pitch model with the sensor data; one or more second coefficientsfor the vehicle are calculated via the processor using a roll model with the sensor data; and a fault in the suspension system is determined via the processor using the first coefficients and the second coefficients.
在各个实施例中,提供了用于确定车辆的悬架系统中的故障的方法、系统和车辆。在一示例性实施例中,在车辆运行期间经由一个或多个车辆传感器获得传感器数据;经由处理器使用俯仰模型与传感器数据一起来计算车辆的一个或多个第一系数;经由处理器使用侧倾模型与传感器数据一起来计算车辆的一个或多个第二系数;以及经由处理器使用第一系数和第二系数来确定悬架系统中的故障。
