The invention relates to the related technical field of engineering machinery, in particular to a power take-off control method and a power take-off device of engineering machinery and the engineering machinery. And then, whether the engineering machinery needs to be preheated or not is determined based on the temperature information, and if it is determined that the engineering machinery needs to be preheated, a corresponding preheating gear is determined based on the temperature information. Therefore, in a low-temperature environment, preheating is carried out before power takeoff, and power takeoff is carried out after preheating is completed, so that power takeoff failure caused by low temperature is avoided, the power takeoff success rate is greatly improved, and the stability of engineering machinery is improved. Moreover, the engineering machinery is preheated through the corresponding gears according to the low temperature degree, preheating is conducted through the high gears under the condition that the low temperature degree is high, the preset efficiency is improved, preheating is conducted through the low gears under the condition that the low temperature degree is low, energy consumption is reduced, and preheating is more reasonable.
本申请涉及工程机械相关技术领域,具体涉及一种工程机械的取力控制方法、取力装置和工程机械,该方法包括首先获取工程机械的温度信息;然后基于温度信息确定是否需要对工程机械进行预热,若确定需要对工程机械进行预热,然后基于温度信息确定对应的预热档位。从而在低温环境下,在取力前先进行预热,在预热完成后,再进行取力,避免低温导致的取力失败,大大提高了取力的成功率,提高了工程机械的稳定性。而且,根据低温程度通过对应的档位对工程机械进行预热,在低温程度较高的情况下通过高档位预热,提高预设效率,在低温程度低的情况下通过低档预热,减小能耗,使预热更加合理。
