Embodiment 1

[0074] Please see attached figure 1 And attached figure 2 , Step 1: When the vehicle has a DPF regeneration demand, the service personnel can click the "Service Regeneration" button on the man-machine interface of the remote data platform 3 to start the remote DPF regeneration control process, and the remote data platform 3 sends a detection to the remote communication module 2 instruction.

[0075] Step 2: After receiving the detection instruction, the remote communication module 2 reads the parameter information from the engine controller 1 through the CAN harness, and sends the parameter information to the remote data platform 3 .

[0076] The parameter information includes vehicle ECU data version information 6K23006A48 and related parameter data. The related parameter data includes engine speed of 800rpm, engine coolant temperature of 75°C, PTO switch status of 0, DOC upstream exhaust temperature of 174°C and total The particle mass is 38.4g, which is used to judge whe...

Abstract

The invention discloses a remote DPF regeneration control method for a vehicle engine. The remote DPF regeneration control method comprises the steps that 1 a remote data platform (3) sends a detection instruction to a remote communication module (2); 2 the remote communication module reads the parameter information and sends the parameter information to a remote data platform; 3 if the service regeneration condition is met, the step 4 is executed, and otherwise, the step 9 is executed; 4 the remote data platform sends a DPF regeneration instruction to the remote communication module; 5 the remote communication module sends a regeneration message to an engine controller to trigger active regeneration of the vehicle DPF; 6 the remote communication module reads the regeneration data in real time and sends the regeneration data to the remote data platform; 7 if the vehicle smoothly enters the DPF active regeneration state, the step 8 is executed, and otherwise, waiting is carried out; 8 if active regeneration of the DPF is normally completed, control is ended, and otherwise, feedback is conducted; and 9 the control is ended. According to the invention, the remote control of the active regeneration of the vehicle engine DPF can be realized through the remote data platform and the vehicle-mounted remote communication terminal.

Description

technical field [0001] The invention relates to a remote control method for an engine, in particular to a remote DPF regeneration control method for a vehicle engine. Background technique [0002] Diesel Particulate Filter (DPF) is installed in the exhaust system of the vehicle diesel engine to capture particulate matter before it enters the atmosphere, thereby effectively reducing the emission of particulate matter. During the long-term operation of the DPF, the gradual increase of the particles in the trap will cause the engine back pressure to increase and cause the engine performance to decline. It is necessary to regenerate the DPF regularly to remove the deposited particles and restore the filter performance of the DPF. [0003] DPF regeneration includes active regeneration and passive regeneration. Active regeneration refers to the use of external energy to increase the temperature inside the filter (for example, to 550°C), causing the particles to ignite and burn. ...
