The invention discloses a method, device and equipment for determining the rotating speed transmission direction of an output shaft, and the method comprises the steps: firstly obtaining the width of a high level outputted by an output shaft rotating speed sensor connected with an AMT when a target vehicle TCU is just powered on; judging whether the high-level width is within a preset range of the high-level width or not; if yes, determining the direction of the output shaft by using the normally calculated rotating speed of the output shaft of the target vehicle; if not, whether the target vehicle is in the gear shifting process or not is judged; and if yes, correcting the preset range of the high-level width by using the whole vehicle acceleration of the target vehicle, and if not, correcting the preset range of the high-level width by using the motor rotating speed of the target vehicle, and subsequently determining the rotating speed direction of the output shaft by using the corrected preset range of the high-level width. Therefore, under the condition that the difference of parts is fully considered, the rotating speed direction of the output shaft can be determined more accurately by correcting the preset range of the high-level width.

    本申请公开一种输出轴转速传方向的确定方法、装置及设备,该方法包括:首先在目标车辆TCU刚上电时,获取与AMT连接的输出轴转速传感器输出的高电平宽度;然后判断该高电平宽度是否位于高电平宽度的预设范围;若是,则利用正常计算出的目标车辆输出轴转速确定输出轴的方向;若否,则判断目标车辆是否在换挡过程中;若在,则利用目标车辆的整车加速度校正高电平宽度的预设范围,若不在,则利用目标车辆的电机转速对高电平宽度的预设范围进行校正,接着后续再利用校正后的高电平宽度的预设范围,确定出输出轴转速方向。这样,在充分考虑了零部件的差异性的情况下,通过修正高电平宽度的预设范围的方式,可以更为准确的确定出输出轴转速方向。
