    Semi-active suspension damping compensation method and device and vehicle

    Freier Zugriff

    The invention relates to a semi-active suspension damping compensation method and device and a vehicle. The method comprises the following steps: when a vehicle runs according to a preset mode, acquiring a parameter value of a target parameter of a vehicle vibration model in real time; a first characteristic value of the target parameter is determined, and the first characteristic value is the difference between the maximum parameter value and the minimum parameter value of the target parameter; according to the first characteristic value, the compensation current of a semi-active shock absorber of the semi-active suspension is determined; and if the compensation current is within the preset compensation current range, damping compensation is conducted on the semi-active shock absorber according to the compensation current. In this way, the accuracy of damping compensation can be effectively improved, and differential damping compensation is carried out on the semi-active shock absorber of each vehicle. And only under the condition that the compensation current is within the preset compensation current range, damping compensation is performed on the semi-active shock absorber through the compensation current, so that unnecessary energy consumption of the vehicle can be avoided, and meanwhile, the performance of the vehicle is prevented from being greatly deteriorated.

    本公开涉及一种半主动悬架阻尼补偿方法、装置和车辆。该方法包括：在车辆按照预设模式行驶时，实时获取车辆振动模型的目标参数的参数值；确定目标参数的第一特征值，其中，第一特征值为目标参数的最大参数值与最小参数值之差；根据第一特征值，确定半主动悬架的半主动减振器的补偿电流；若补偿电流在预设的补偿电流范围内，则根据补偿电流，对半主动减振器进行阻尼补偿。如此，能够有效提高阻尼补偿的精确性，对每辆车的半主动减振器进行差异化的阻尼补偿。并且仅在补偿电流在预设的补偿电流范围内的情况下，通过该补偿电流对半主动减振器进行阻尼补偿，能够避免不必要的车辆能量的消耗，同时避免车辆性能大幅度恶化。
