The invention relates to a loader ramp reversing control method which comprises the following steps: responding to a reversing request, and acquiring loader state information; according to the loading machine state information, judging the working condition and acquiring a working condition judgment result; according to the working condition judgment result, sending a current reducing instruction to a clutch electromagnetic valve in the current driving direction, controlling a clutch in the current driving direction to be disengaged while sending a current increasing instruction to a clutch electromagnetic valve in the target driving direction, and controlling the clutch pressure in the target driving direction to reach the set maximum value. The control system comprises a controller used for storing instructions and controlling execution of the control method. The optimal control problem of the loader in ramp reversing is solved, the technical effect of optimal smoothness in the uphill reversing process of the loader is achieved, the technical effect of optimal dynamic property in the downhill reversing process of the loader is achieved, and meanwhile, the overload risk of the clutch can be effectively avoided.
本发明涉及一种装载机坡道换向控制方法,响应换向请求,获取装载机状态信息;根据装载机状态信息,对工况条件进行判定,得到工况判定结果;根据工况判定结果,发送降低电流指令给当前行驶方向的离合器电磁阀,控制当前行驶方向的离合器脱开,同时,发送提高电流指令给目标行驶方向的离合器电磁阀,控制目标行驶方向的离合器压力达到设定最大值。控制系统包括控制器,用于存储指令及控制执行本发明的控制方法。本发明的方法和系统,解决了装载机在坡道换向的最佳控制问题,实现装载机上坡换向过程平顺性最佳的技术效果,实现装载机下坡换向过程动力性最佳的技术效果,同时,能够有效避免离合器过载风险。
