Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a replaceable store search system for a diesel particulate filter of a diesel engine vehicle and an in-vehicle device of the diesel engine vehicle.
[0002]
[Prior art]
As a device for removing particulates such as graphite contained in exhaust gas of a diesel engine vehicle, a diesel particulate capturing device called a particulate trap is known. The diesel particulate trap has a filter made of silicon carbide ceramics with a fiber structure or honeycomb structure installed in the exhaust passage, and filters the particulates such as graphite in the exhaust gas when the exhaust gas passes through the filter. It captures and exhausts clean exhaust gas.
[0003]
Such a filter is called a diesel particulate filter (DPF). Since the diesel particulate removal filter is clogged by trapping the particulates, it is necessary to perform regeneration to eliminate the filter clogging when the trapped amount of particulates reaches a predetermined value. For this reason, in the conventional diesel particulate capturing device including the diesel particulate removal filter, each device is provided with a heater and burner for filter regeneration, and the particulates captured by the filter by the heater and burner are burned and ashed in the in-vehicle device. Thus, the filter is regenerated.
[0004]
[Problems to be solved by the invention]
Conventionally, in order to regenerate the filter, it is necessary to provide a heater and burner for regenerating the filter in each diesel particulate trap installed in each diesel engine vehicle, which increases the cost of the device and increases the size of the device. The in-vehicle property becomes worse.
[0005]
The present invention was made to solve the above-described problems. The diesel particulate removal filter can be attached to and detached from the diesel engine vehicle, and the diesel particulate removal filter is removed from the diesel engine vehicle and exchanged at a store. It is an object of the present invention to provide an exchangeable store search system and an on-vehicle device for a diesel engine vehicle that search for a store on which the diesel particulate filter can be exchanged on the vehicle.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a replaceable store search system for a diesel particulate filter for a diesel engine vehicle and an in-vehicle device for a diesel engine vehicle according to the present invention will be described in detail with reference to the accompanying drawings.
[0027]
FIG. 1 shows an embodiment of a replaceable store search system for a diesel particulate filter for a diesel engine vehicle according to the present invention. As a precondition of this system, a diesel particulate filter (DPF) 11 is detachably installed in the middle of the exhaust passage of the diesel engine vehicle 10. The diesel particulate filter 11 that needs to be regenerated is removed from the diesel engine vehicle 10 at stores such as a gas station 20 that sells diesel engine fuel, a car goods store 21, a maintenance station 22, and a repair factory 23. Replaced with a new or regenerated diesel particulate filter.
[0028]
These stores 20 to 23 have a stock of new or regenerated diesel particulate removal filters, and each store or general store has equipment for regenerating used diesel particulate removal filters. The replaceable store search system for the diesel particulate removal filter is a search system for searching on the vehicle for a store where the diesel particulate removal filter 11 can be replaced.
[0029]
The search service provider side of this system includes the DPF inventory database 30 storing inventory data including the location of each store, the diesel particulate filter (DPF) type and type, the filter replacement price of each store, diesel engine fuel, etc. A price database 31 storing sales price data and a search service providing computer 32 are installed.
[0030]
The search service providing side computer 32 is communicably connected to each of the stores 20 to 23 through a communication network 40 including the Internet. The search service providing side computer 32 receives the latest information on the inventory data of the diesel particulate removal filter 11 (the type of filter, the number of inventory for each type). The DPF inventory database 30 is updated and written, and the filter replacement price of each store and the sales price of diesel engine fuel and the like are written to the price database 31 and a conditional search of these databases is performed. Sales inventory information management of each store 20-23 can be performed by a POS (point of sale) system.

As shown in FIG. 2, the search result is displayed on the screen as a list of the name, address, address, etc. of the corresponding store, or the current position of the vehicle is displayed on the screen display map. Along with the mark X, a mark A or B such as an arrow is displayed for the corresponding store, or a combination thereof. This screen display can also be set to be changeable by the mode setting by the user. Further, the terminal device 62 of the inquiry source diesel engine vehicle 10 displays the price information of the corresponding store transmitted from the search service providing side computer 32 on the display for each store in the above-described list display.
[0040]
Further, the search service providing side computer 32 gives road traffic congestion state data to a store in stock from the current position of the inquiry source diesel engine vehicle 10 based on the road traffic information acquired from the road traffic information communication system 50. Then, the search result can be transmitted to the terminal device 62 of the diesel engine vehicle 10 as the inquiry source. As a result, the terminal device 62 of the inquiry source diesel engine vehicle 10 receives the above-described search result and the congestion state data received from the search service providing side computer 32, and the inventory is stored from the current position of the diesel engine vehicle 10 together with the search result. The traffic congestion state of a road to a certain store is displayed on the display.
[0041]
As a result, the driver of the diesel engine vehicle 10 can change the diesel particulate removal filter 11 of his / her vehicle and the diesel particulate removal filter that matches the model and type, and the store close to the current position on the vehicle Now you can know exactly.
[0042]
In addition, the driver of the diesel engine vehicle 10 can know the price information of the store as well as the store where the diesel particulate filter 11 of the vehicle and the diesel particulate filter that matches the model and type can be exchanged. Become.
[0043]
In addition, the driver of the diesel engine vehicle 10 can know the traffic congestion state of the road to the store where the diesel particulate filter 11 of the vehicle and the diesel particulate filter that matches the model and type can be exchanged. You can choose a store where there is no traffic jam.
[0044]
Further, when the fuel supply cycle and the regeneration cycle of the diesel particulate removal filter are combined, if the corresponding store is the gas station 20, the fuel supply cycle is performed every time or every several times at the gas station 20. Therefore, the diesel particulate filter can be exchanged at the gas station 20 that stops by, and convenience is improved.
