The invention relates to an electric vehicle torque filtering method and system, computer equipment and a storage medium. The method comprises the following steps: collecting vehicle driving information in a vehicle driving state, and judging a driving mode of a vehicle according to the vehicle driving information; according to the types of the driving modes, the torque rising rate and the torque falling rate of the vehicle under different driving modes are set; limiting the required torque of the driver through the torque rising rate and the torque falling rate; and torque zero-crossing processing is conducted according to the required torque for limiting vehicle running. A driving mode is accurately judged through vehicle information, the torque required by a driver is limited based on the driving mode, and finally the filtered torque is obtained through torque zero-crossing processing. Not only can the required torque of a driver under various operation working conditions be quickly responded to, the driving pleasure is improved, but also the adverse effect of tooth beating caused by a gear clearance can be effectively reduced when the vehicle driving working condition and the braking working condition are mutually switched, and the driving comfort is improved.

    本申请涉及一种电动车扭矩的滤波方法、系统、计算机设备和存储介质。该方法包括:收集车辆行驶状态下的车辆驾驶信息,根据所述车辆驾驶信息判断车辆的驾驶模式;根据所述驾驶模式的种类,设置不同驾驶模式下的车辆的扭矩上升率和扭矩下降率;通过所述扭矩上升率和所述扭矩下降率限制驾驶员的需求扭矩;根据限制车辆行驶的需求扭矩进行扭矩过零处理。通过车辆信息精准判断驾驶模式,并基于驾驶模式限制驾驶员需求扭矩,最后通过扭矩过零处理得到滤波后的扭矩。既能迅速响应驾驶员在各种操作工况下的需求扭矩,提升驾驶乐趣,又能在车辆驱动工况与制动工况相互切换时有效降低齿轮间隙带来的打齿不利影响,提升驾驶舒适性。
