- DPF diesel particulate filter
- PM particulate matter contained in exhaust gas of an internal combustion engine
- a vehicle equipped with a DPF performs DPF regeneration in which DPF is combusted and regenerated by a heater or the like (particularly soot of PM is combusted) in order to prevent functional degradation due to filter clogging. Kite is also called soot.
- This DPF regeneration is automatically started during traveling under the control of an engine control unit (ECU) that controls the engine. In addition, when regeneration during running is insufficient, it may be started by a driver's switch operation when the vehicle is stopped.
- ECU engine control unit
- the DPF system calculates in advance a time that is a standard for ending the DPF regeneration, and terminates the DPF regeneration based on the calculated time.
- the reference time for completing the DPF regeneration is used only by the ECU for controlling the DPF regeneration, and is not notified to the driver. Accordingly, the driver cannot know the approximate time for ending the DPF regeneration, and cannot make an efficient travel plan with DPF regeneration in mind.
- an object of the present invention is to propose a filter regeneration system, an ECU, and a filter regeneration program that can make an efficient travel plan to the driver by notifying the estimated regeneration remaining time of the DPF.
- the present invention provides a DPF filter regeneration system that collects particulate matter, and includes an ECU that controls the regeneration process of the DPF filter.
- the present soot remaining amount (Rp) is calculated based on the model, and the present soot remaining amount (Rt) is calculated based on a theoretical time model indicating the remaining soot amount, whichever is larger.

Further, the scheduled end time may be displayed by referring to the current time. The soot remaining amount display unit 31 is instructed from a display instruction unit 120E described later.
