The invention discloses a protection method, device and equipment for a vehicle transmission shaft and a storage medium, and the method comprises the steps: calculating the allowable maximum output torque value of an engine under each gear of a gearbox based on the bearing torque of the transmission shaft and the current transmission speed ratio of the gearbox; according to the difference value between the current transmission speed ratio of the gearbox and the pre-stored speed ratio of each gear of the gearbox, the current operation gear of the gearbox is determined; the maximum engine output torque value allowed by the current operation gear is determined, and the maximum accelerator output value corresponding to the maximum engine output torque value allowed by the current operation gear is determined; and the current accelerator value is compared with the maximum accelerator output value, and the minimum operation is carried out so as to limit engine accelerator output. The transmission shaft is protected by limiting the output of the accelerator, and the transmission shaft is prevented from being damaged due to overlarge torque output of the engine.

    本发明公开了一种车辆传动轴的保护方法、装置、设备及存储介质,其中该方法包括步骤:基于传动轴的承受扭矩和当前变速箱传动速比,计算变速箱各个档位下所允许发动机最大输出扭矩值;根据当前变速箱传动速比与预先存储的变速箱各档位速比的差值,确定当前变速箱运行档位;确定所述当前运行档位所允许发动机最大输出扭矩值,并确定所述当前运行档位所允许发动机最大输出扭矩值所对应的最大油门输出值;将当前油门值与所述最大油门输出值进行对比,进行取小操作,以限制发动机油门输出。本申请通过限制油门输出的形式保护传动轴,避免传动轴因发动机扭矩输出过大而损坏。
