Light bus instrument DPF regeneration alarm system and method

Abstract

The invention provides a light bus instrument DPF regeneration alarm system and method. The light bus instrument DPF regeneration alarm system comprises an engine controller EMS, a whole bus controller ECU, a diesel particulate filter DPF and a bus instrument desk. The EMS is used for monitoring and sending state information of the DPF to a displayer of a passenger car instrument desk. The ECU is used for judging whether the vehicle meets a manual regeneration condition or not at present, and then the DPF is controlled to execute a regeneration request; the DPF is used for executing a manual regeneration instruction from the ECU; the passenger car instrument desk is used for reminding a driver to carry out DPF manual regeneration when the DPF is blocked. The DPF blockage signal is grabbed and displayed on the instrument desk, so that a driver is reminded to perform manual regeneration operation on the DPF in time when the DPF of the vehicle is blocked, the DPF blockage problem failure rate is reduced, the cost of accessories such as the DPF and a catalyst exhaust front pipe is saved, and the discharge amount of three pollutants such as HC, CO and PM is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of automobile alarm system design, in particular to a DPF regeneration alarm system and method for a light passenger vehicle instrument. Background technique [0002] At present, the operation of the DPF interface of the instrument panel of the light passenger vehicle is complicated, and the set functions cannot be easily applied by the user, so that the user cannot deal with it in time when the vehicle DPF is blocked, which affects the use of the vehicle. [0003] Therefore, the present invention designs a DPF regeneration alarm system and method for a light-duty passenger vehicle. By grabbing the DPF jam signal and displaying it on the dashboard, the present invention reminds the driver to perform manual regeneration of the DPF in time when the vehicle DPF is jammed. . SUMMARY OF THE INVENTION [0004] Aiming at the deficiencies of the prior art, the present invention designs a DPF regeneration alarm sy...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention designs a DPF regeneration alarm system and method for a light passenger car instrument. By grabbing the DPF blockage signal and displaying it on the instrument panel, it reminds the driver to timely reset the DPF when the vehicle DPF is blocked. Manual regeneration operation reduces the failure rate of DPF blockage, saves the cost of accessories such as DPF and catalytic converter exhaust front pipe, and effectively reduces the emission of three pollutants such as HC, CO, and PM.
