Particle trap regeneration method and device, storage medium and controller

The invention belongs to the technical field of vehicle engineering, and particularly relates to a particle trap regeneration method and device, a storage medium and a controller. The particulate trap is reversely installed and is in butt joint with the rotary purging component, and regeneration of the particulate trap is achieved by externally hanging the particulate trap on an engine tail gas pipeline. Wherein in order to improve the regeneration effect, a cyclic or intermittent variable working condition control process can be introduced; pulsating tail gas output is introduced by setting and switching the first type of working conditions and/or the second type of working conditions; different excitation states of the tail gas can be realized by adopting a high-load high-rotating-speed working condition and a low-load low-rotating-speed working condition respectively; in addition, a preset lean-burn working condition and high-temperature tail gas configuration can be combined, so that the regeneration effe
