Particle trap regeneration control method and related device

The invention discloses a particle trap regeneration control method and a related device, the current carbon loading capacity of a vehicle is obtained, if the current carbon loading capacity is larger than or equal to a first threshold value, the vehicle can be controlled to run at a low gear and a high rotating speed firstly, then the opening degree of an engine throttle valve of the vehicle is reduced, fuel injection is interrupted, and the carbon loading capacity of the vehicle is controlled to be larger than or equal to the first threshold value. And the amount of oxygen entering the particulate filter is greatly increased, combustion of soot particles in the particulate filter is accelerated, the current carbon loading capacity is reduced, and fuel injection is recovered or the opening degree of an engine throttle valve is increased until the current carbon loading capacity is smaller than or equal to a second threshold value. Therefore, only a passive regeneration mode is utilized, by increasing the exh
