Problems solved by technology

[0002] At present, due to the fact that the main material of the vehicle particle filter is prone to fragmentation when the temperature exceeds a certain level, the damage rate of the vehicle particle filter is high. In view of the problem of the high damage rate of the vehicle particle filter, Usually, in the case of non-active regeneration of the vehicle, the inlet temperature of the particulate filter is used as the reference, and the temperature model is used to judge whether the internal temperature of the particulate filter exceeds the temperature threshold, so as to enrich the air-fuel ratio and reduce the temperature. Technical problem with high damage rate of particle filter in case of regeneration
[0003] Aiming at the problem of the high damage rate of the particle filter when the vehicle enters active regeneration in the above-mentioned prior art, no effective solution has been proposed so far

Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a control method for a vehicle trap is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

[0027] figure 1 is a flow chart of a control method for a particle trap according to an embodiment of the present invention, such as figure 1 As shown, the method may include the following steps:

[0028] Step S102, acquiring the current working state of the particle trap.

[0029] In the technical solution provided in S102 of the above steps in the embodiment of the present invention, by running the control program of the vehicle electronic control unit (Electronic Control Unit, referred to as ECU), various items including ...

Embodiment 2

[0091] The technical solutions of the embodiments of the present invention are illustrated below with reference to the preferred embodiments.

[0092] During vehicle driving, the particulate filter is very important to the emission of vehicle particulate matter. Therefore, in the exhaust temperature protection of the particulate filter, the particle trap is coordinated by each module according to the temperature threshold and time under the condition of active vehicle regeneration. The protection of the filter can bring more comprehensive and timely protection to the particle filter.

[0093] At present, for the protection of the particle filter, the traditional exhaust temperature protection measures are based on the temperature T at the inlet of the particle filter during non-active regeneration, and use the temperature model to calculate the temperature inside the particle filter (T0) , once this temperature exceeds a certain temperature threshold, where the temperature thr...
