Regeneration verification method, device and system for hybrid engine

The invention provides a regeneration verification method, device and system for a hybrid engine, and the method improves the load of the hybrid engine by keeping the rotating speed of a diesel engine of the hybrid engine at a preset rotating speed and adjusting the torque of a motor of the hybrid engine, so that the subsequent judgment is more accurate, and the efficiency of the hybrid engine is improved. And then whether regeneration can be carried out or not is judged according to the pressure difference, whether the current hybrid engine is suitable for regeneration operation or not can be accurately judged, the judgment accuracy of the hybrid engine is improved, and therefore the problems that in an existing scheme, checking is not carried out before engine regeneration, and the efficiency is high are solved. And therefore, the problem of burn-through of a DPF (diesel particulate filter) caused by regeneration is solved. 本申请提供了一种混动用发动机的再生校验方法、装置和系统，该方法通过保持混动用发动机的柴油机的转速为预设转速不变，并调节混动用发动机的电机的扭矩，来提高混动用发动机的负荷
