The invention relates to a vehicle crane control method and device, and a vehicle crane. The method comprises the following steps of determining a voltage target value according to a received input signal for starting a crane from a control handle; determining an intermediate voltage value according to a first voltage value and the voltage target value; and when each signal output time point of afirst control time period is reached, determining and outputting a first output voltage corresponding to the signal output time point, wherein the first output voltage at a first target time point isthe intermediate voltage value, the first output voltage of a time end point of a first control time period is a voltage target value, and in the first time period formed by a time starting point of the first control time period and the first target time point, an increasing amplitude of the first output voltage corresponding to a latter signal output time point is increased along with the increase of time compared with the increasing amplitude of the first output voltage corresponding to a former signal output time point. Therefore, good micro-motion performance is achieved on control of thecrane, and large shaking in a starting process is prevented.
本公开涉及一种车辆起重机控制方法、装置及车辆起重机。所述方法包括:根据接收到的来自控制手柄的用于起动起重机的输入信号,确定电压目标值;根据第一电压值和电压目标值,确定中间电压值;在到达第一控制时段的各个信号输出时间点时,确定并输出与该信号输出时间点对应的第一输出电压,第一目标时间点的第一输出电压为中间电压值,第一控制时段的时间终点的第一输出电压为电压目标值,在由第一控制时段的时间起点和第一目标时间点构成的第一时段内,后一信号输出时间点对应的第一输出电压相较于前一信号输出时间点对应的第一输出电压的增长幅度随时间的增加而增大。这样,对起重机的控制具有良好的微动性,防止启动过程中出现较大晃动。
