Title:
FILTER REPRODUCTION SYSTEM, ECU AND FILTER REPRODUCTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/179277
Kind Code:
A1
Abstract:
The present invention proposes a filter reproduction system, an ECU and a filter reproduction program which enable formation of an efficient traveling plan for a driver by notifying an estimated remaining DPF reproduction time.
A filter reproduction system for a DPF for trapping particulate matter is provided with an ECU for controlling filter reproduction processing of the DPF. The ECU calculates a remaining soot amount (Rp) at present on the basis of a physical model indicating an actual remaining soot amount, calculates a remaining soot amount (Rt) at present on the basis of a time model indicating a theoretical remaining soot amount, calculates an estimated remaining DPF reproduction time (Tp, Tt) at present on the basis of a larger one of the remaining soot amounts (Rp, Rt), and notifies a driver of the estimated remaining DPF reproduction time (Tp, Tt).
