Problems solved by technology

In general, when the engine control unit performs active regeneration control, if the driving conditions limit the vehicle's long-term low-speed driving, repeated low-temperature cold starts, and long-term idling conditions, it is also likely that the GPF particles will exceed the standard.
If the GPF load is too high, it will cause the risk of engine performance degradation and exhaust overheating, and when the GPF load i

Abstract

The embodiment of the invention discloses a particle catcher state reminding method, device and system and a storage medium. An engine control unit can determine the current carbon load of a particlecatcher according to collected vehicle operation condition information and compares the current carbon load with a first carbon load threshold. If the current carbon load exceeds the first carbon loadthreshold, the particle catcher is controlled to execute active regeneration operation, the active regeneration state of the particle catcher is determined, reminding information is generated, and the active regeneration state and the reminding information are sent to a vehicle instrument and a client, so that the vehicle instrument and the client display the active regeneration state and the reminding information. In this way, a driver senses the driving condition difference due to the active regeneration operation in time, thereby avoiding complaints. Moreover, the driver can timely deal with a vehicle according to the display information, so that the situation that the driver knows vehicle faults only when too many particles are accumulated and accordingly normal use is affected is avoided.

Description

technical field [0001] Embodiments of the present invention relate to automobile control technology, and in particular to a method, device, system and storage medium for reminding the state of a particle trap. Background technique [0002] China's sixth-stage emission regulations have strict requirements on the emission of particulate matter from vehicles. The National V regulations have a particulate matter emission requirement of 0.0045g / km, and the National VI regulations have tightened the requirements to 0.003g / km and stipulated the number of particulate matter. For many engines Must be equipped with gasoline engine particulate filter (Gasoline Particulate Filter, referred to as GPF). A GPF is a ceramic filter installed in the exhaust system of a gasoline engine, which traps particulate emissions before they enter the atmosphere. [0003] The engine control unit of the car can oxidize and burn excessive particulate matter through active regeneration and passive regener...
