Abstract

The invention provides a diesel vehicle DPF pre-diagnosis system and method, and relates to the technical field of DPF pre-diagnosis. The diesel vehicle DPF pre-diagnosis system comprises a remote vehicle-mounted terminal, a vehicle networking cloud platform, a mobile terminal, an ECU and a WEB terminal, the vehicle networking cloud platform communicates with the mobile terminal through TCP / IP, the WEB terminal communicates with the vehicle networking cloud platform through TCP / IP, the vehicle networking cloud platform communicates with the remote vehicle-mounted terminal through 4G / 5G, and the ECU communicates with the remote vehicle-mounted terminal through CAN. According to the diesel vehicle DPF pre-diagnosis system and the method, oil consumption and emission deterioration caused by large-degree blockage of the DPF can be avoided, DPF burnout or corresponding serious faults caused by DPF blockage and OBD fault missing report can be avoided, the consistency of the DPF can be evaluated, DPF batch accidents can be avoided, early warning and driver guidance can be performed in advance, and DPF blockage faults can be avoided.

Description

technical field [0001] The invention relates to the technical field of DPF pre-diagnosis, in particular to a diesel vehicle DPF pre-diagnosis system and method. Background technique [0002] DPF (Diesel Particulate Filter) has a very effective removal effect on both the quality (PM) and the number (PN) of diesel particulate matter. Diesel engine DPF technology is currently recognized as one of the most effective technologies for reducing diesel particulate emissions. From the market statistics of China V and China VI diesel engines, DPF failure is a relatively high failure rate failure, common problems include DPF burnout (more cordierite), DPF clogging (more SiC), oil dilution problems , The regeneration mileage is short, the parking regeneration is too long, and the regeneration failure is too high. DPF pre-diagnosis is to carry out health checks, fault warnings, flexible maintenance (predictability and preventiveness), etc. before a fault (OBD fault or non-OBD fault) oc...
