The embodiment of the invention provides a braking method and device, engineering machinery and a machine readable storage medium, and belongs to the technical field of engineering machinery. The method comprises the steps that operation information of the engineering machinery is obtained, whether the engineering machinery meets brake triggering conditions or not is determined based on the operation information, and under the condition that the engineering machinery meets the brake triggering conditions, an engine brake and an eddy current retarder of the engineering machinery are controlled to conduct braking. The intelligence of braking control of the engineering machinery is improved in an active triggering mode, braking is carried out jointly through an eddy current retarder and an engine brake, and the braking torque is rapidly increased; and the first engine rotating speed of the braked engineering machinery is obtained, whether further auxiliary braking is needed or not can be judged through the first engine rotating speed, the starting rate of the auxiliary braking device is determined based on the first engine rotating speed, and the auxiliary braking device is controlled to conduct auxiliary braking according to the starting rate. And system resources are reasonably allocated, and the braking efficiency of the engineering machinery is improved.

    本发明实施例提供一种制动方法、装置、工程机械及机器可读存储介质,属于工程机械技术领域。方法包括:获取工程机械的运行信息,基于运行信息确定工程机械是否满足制动触发条件,在工程机械满足制动触发条件的情况下,控制工程机械的发动机制动器和电涡流缓速器进行制动,通过主动触发的方式提升工程机械制动控制的智能性,且利用电涡流缓速器与发动机制动器共同进行制动,快速提升制动力矩;获取制动后工程机械的第一发动机转速,第一发动机转速可判断是否需要进一步的辅助制动,基于第一发动机转速确定辅助制动装置的开启率,并根据开启率控制辅助制动装置进行辅助制动。合理调配系统资源,提升对工程机械的制动效率。
