Problems solved by technology

However, there are still certain potential safety hazards in this regeneration processing judgment condition. For example, when the vehicle stops on an inclined road and the accelerator is not fully released, it is easy for the vehicle to move by itself during regeneration processing.

Abstract

The embodiment of the invention discloses a parking regeneration control method and system, a diesel vehicle and a storage medium. The parking regeneration control method comprises the steps that whenjudging that a vehicle requires parking regeneration, vehicle state parameters and engine operation state parameters are obtained from an engine electronic control unit and a vehicle electronic control unit, whether the vehicle state parameters and the engine operation state parameters meet a first preset condition or not is judged, and if so, a parking regeneration mode is started; and state parameters of a diesel catalytic oxidizer and a diesel particle filter in a post-treatment system are obtained, whether the state parameters of the diesel catalytic oxidizer and the diesel particle filter meet a second preset condition or not is judged, and if so, regeneration is carried out continually. According to the parking regeneration control method and system, the diesel vehicle and the storage medium, by comprehensively considering an operation state of the vehicle and an engine, the safety of the vehicle and the engine before the regeneration treatment is ensured, and the vehicle capable of being driven normally after the regeneration is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of engine aftertreatment, and in particular to a parking regeneration control method, system, diesel vehicle and storage medium. Background technique [0002] With the increasingly stringent national automobile exhaust emission regulations, relevant government departments have strictly limited the exhaust emissions of diesel locomotives. Currently, light vehicles mainly use diesel particulate filters to filter the exhaust, and heavy vehicles mostly use in-cylinder combustion purification technology to reduce Exhaust gas, but after the implementation of China VI emission standards in the future, no matter light vehicles, heavy vehicles or construction machinery, DPF (Diesel Particulate Filter, Diesel Particulate Filter) will be required to make the exhaust emissions meet the regulatory requirements. At the same time, for diesel locomotives in use in the market, the government has als...
