Abstract

The invention discloses a vehicle data processing method and device, a storage medium and a processor. The method comprises the steps that the carbon loading capacity and the pressure difference value of a gasoline engine particle trap of a vehicle are obtained; respectively comparing the carbon loading capacity and the pressure difference value with preset values to obtain a first comparison result; according to the first comparison result, the active regeneration state of the gasoline engine particle trap matched with the vehicle is determined, and the active regeneration state comprises at least one of the following states: the active regeneration state, the limited active regeneration state and the mixed limited active regeneration state; according to the active regeneration state, control information is generated, and the control information comprises at least one of an instruction for maintaining the current active regeneration state of the gasoline engine particle trap and an instruction for correcting air-fuel ratio parameters. By the adoption of the technical scheme, the problem that the GPF of the gasoline engine is prone to being blocked due to the fact that exhaust back pressure rises is solved.

Description

technical field [0001] The present invention relates to the technical field of vehicle data processing, in particular to a vehicle data processing method, processing device, storage medium and processor. Background technique [0002] GPF (gasoline particulate filter), also known as gasoline engine particulate filter, is mainly used in in-cylinder direct injection (gasoline direct injection, GDI) gasoline engines to reduce particulate matter emissions to meet increasingly stringent regulatory requirements. The GPF is a wall-flow structure, which achieves the purpose of removing soot by trapping the soot particles in the exhaust on the wall surface, but the continuous accumulation of soot particles will cause the GPF to be blocked, causing the exhaust back pressure to increase, Engine fuel economy deterioration and other issues. In order to restore the filtering function of the GPF, it is necessary to periodically regenerate the GPF full of soot particles. [0003] The ECU o...
