The invention relates to the technical field of control of engineering vehicles, in particular to an overhead working truck boom control method, device and equipment, a storage medium and a program product.The method comprises the steps that when a starting instruction of an overhead working truck boom is received, a preset starting current is output to a hydraulic multi-way valve, the current output to the hydraulic multi-way valve is controlled to be increased from the starting current to a preset starting buffer current, and then the hydraulic multi-way valve is controlled to operate for a preset first duration according to the starting buffer current; and then the current output to the hydraulic multi-way valve is controlled to be increased from the starting buffer current to the target current. Therefore, current control which is not enough to enable the arm support to act can be removed, build-up pressure is reduced, and shaking of a working column is reduced. In addition, inertia enabling of the current output to the hydraulic multi-way valve which is increased from the starting current to the preset starting buffer current can be consumed, and jitter of the work bar is further reduced.

    本发明涉及工程车辆的控制技术领域,具体涉及一种高空作业车的臂架控制方法、装置、设备、存储介质及程序产品,其中方法包括:当接收到高空作业车臂架的启动指令时,向液压多路阀输出预设的启动电流,并控制输出至液压多路阀的电流由启动电流增加至预设的启动缓冲电流,之后控制液压多路阀按照启动缓冲电流运行预设第一时长;之后控制输出至液压多路阀的电流由启动缓冲电流增加至目标电流。由此可以去除掉不足以使臂架动作的电流控制,减小憋压,减少工作栏的抖动;并且可以消耗掉输出至液压多路阀的电流由启动电流增加至预设的启动缓冲电流的惯性使能,进一步减少工作栏的抖动。
