MANAGEMENT SYSTEM AND METHOD FOR EXHAUST PURIFICATION APPARATUS
First Claim
1. A management system for an exhaust purification apparatus, the exhaust purification apparatus comprising:
- a filter disposed in an engine exhaust system, the filter for trapping particulate matter contained in exhaust gases;
a regenerating device for regenerating the filter by burning to remove the particulate matter deposited in the filter; and
operating means for operating the regenerating device,the exhaust purification apparatus being mounted in a vehicle that is to be rented to a user by an administrator and later returned to the administrator by the user, the system comprising;
amount of deposits acquisition means for acquiring an amount of deposits of the particulate matter deposited in the filter; and
billing means for billing a maintenance charge according to the amount of deposits at returning acquired by the amount of deposits acquisition means.

Abstract
In a server 10, a standard setting section 11 establishes a standard amount of deposits and a standard amount of money of a maintenance charge in advance; a first calculating section 12 calculates the maintenance charge by multiplying the standard amount of money by a ratio of a deposition level at returning to a standard deposition level; a memory section 13 stores in memory an engine operating time, the number of regeneration sequences performed, and a reduction coefficient table; a second calculating section 14 establishes a reduction coefficient based on the reduction coefficient table and reduces the maintenance charge after reduction by multiplying the maintenance charge calculated by the first calculating section 12 by the reduction coefficient; and a third calculating section 15 calculates an amount of refund by subtracting the value of the maintenance charge from the value of a maintenance guarantee.
