本发明适用于割草车技术领域,提供了割草车陡坡缓降的方法、控制装置及计算机可读存储介质,所述方法包括步骤:获取割草车的倾斜角度、油门状态以及电机转动方向;根据所述倾斜角度、所述油门状态以及所述电机转动方向确定所述割草车是否处于下坡状态;当所述割草车处于下坡状态时,根据所述油门状态确定当前所述割草车的目标车速;获取所述割草车的当前车速;当所述当前车速与所述目标车速的速度差大于第一预设阈值时,根据所述当前车速与所述目标车速调整电机的刹车占空比,以使所述当前车速与所述目标车速的速度差小于第二预设阈值,其中,第一预设阈值大于或等于所述第二预设阈值。本发明实施例在下坡时驾驶体验效果良好,安全性高。

    The invention is applicable to the technical field of mowing vehicles, and provides a mowing vehicle steep slope slow descending method, a control device and a computer readable storage medium. The method comprises the following steps: acquiring an inclination angle, an accelerator state and a motor rotation direction of the mowing vehicle; determining whether the mowing vehicle is in a downhill state or not according to the inclination angle, the accelerator state and the motor rotation direction; when the mowing vehicle is in a downhill state, determining the current target vehicle speed ofthe mowing vehicle according to the accelerator state; obtaining the current speed of the mowing vehicle; when the speed difference between the current vehicle speed and the target vehicle speed is greater than a first preset threshold value, adjusting the brake duty ratio of a motor according to the current vehicle speed and the target vehicle speed, so that the speed difference between the current vehicle speed and the target vehicle speed is controlled to be smaller than a second preset threshold value, wherein the first preset threshold value is larger than or equal to the second preset threshold value. According to the embodiment of the invention, the driving experience effect is good and the safety is high during downhill running.
