BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an overall configuration diagram of a network type eco-drive diagnostic system (hereinafter referred to as “eco-drive diagnostic system”) according to one embodiment of claims 1 to 3, claim 5 and claim 7. Fig. 2 shows a block diagram of the Eco Drive Diagnosis System. As shown in Fig. 1, the Eco Drive Diagnosis System according to this embodiment is installed at the entrance toll gate of a toll road with a distance toll system as the target road. Entrance ETC (Non-stop automatic toll collection system: Electronic Tol ICI lection System) 1 and the exit ETC 3 installed at the exit toll booth. Is divided into three specified sections (sections 1 to 3) in advance, and traveling data is periodically transmitted from the running truck (target vehicle) 5 to the server 9 on the center 7 (base station) side. Server 9 Driving data is accumulated for each section of the target road in the country. The server 9 compares the transmitted travel data with the accumulated travel data in the same section in the past. This system ranks live and distributes this Eco Drive Rank information to Track 5 in real time. Track 5 is equipped with the terminal 1 1 shown in Fig. 2.

[0018] Terminal 1 1 receives the radio wave from GPS satellite 1 3 and detects the current position of track 5 GPS receiver (GPS receiver) 1 5 and ETC gates 1 7 at the entrance toll gate ETC on-board equipment that receives entrance information from and receives toll information from the roadside antenna 23 installed at the ETC gate 21 at the exit toll gate 25 ECU (control unit) 27, communication interface unit 29, and display unit 30, GPS receiver 15 and ETC on-board unit 25, display unit 30 are connected to ECU 27, and ETC on-board unit 25 is connected to ETC A card is inserted. The display unit 30 is a liquid crystal monitor installed on the instrument panel in the passenger compartment of the truck 5.

Furthermore, a fuel flow meter 31 that measures fuel consumption during traveling and an odometer 33 that measures traveling distance are mounted on the truck 5, and these are also connected to the ECU 27.

[0020] Then, when the track 5 starts, the ECU 27 first transmits the position information from the GPS receiver 15 to the center 7 side via the communication interface 29, and thereafter periodically (for example, 1 At every 0 minute interval), the traveling data of the truck 5 that is traveling, that is, the position information of the 0-5 receiver 15 and the fuel consumption data of the fuel flow meter 31 (fuel consumption data since the last transmission) The mileage data of the odometer 33 (the data of the mileage since the previous transmission) is transmitted to the center 7 side via the communication interface unit 29.

On the center 7 side, the travel data transmitted from the track 5 is sequentially input to the server 9 via the communication interface unit 35.

[0022] The truck 5 and the server 9 (center 7) are connected to each other by, for example, a bucket-communication network that is well-known for mobile communications, and the operation manager (of truck 5 using the eco-drive diagnostic system of this embodiment ( For example, the carrier) is the center By making a contract with 7 in advance, vehicle information such as the vehicle type of truck 5 and the engine exhaust amount is registered in the center 7 in advance, and vehicle identification data is assigned to each truck 5. For this reason, when the ECU 2 7 sends the position information to the server 9 side when the truck 5 starts, or when the running data is periodically sent to the server 9 side while the truck 5 is running, the identification of the truck 5 itself is performed. Data is sent to server 9 at the same time.

[0023] Then, as shown in Fig. 1, when the truck 5 enters the toll road, which is the service target of the Eco Drive Diagnosis System, and passes through the ETC gate 17, the ETC vehicle-mounted device 25 is the roadside antenna as described above. 1 The entrance information is received from 9, but when ETC OBE 25 receives the entrance information in this way, ECU 27 knows that ETC information that truck 5 has entered section 1 (section 1 entry information; entrance information). ) Is sent to the server 9 side along with the identification data and driving data.

[0024] After that, the truck 5 traveling in the section 1 sends the identification data and the traveling data of the truck 5 itself to the server 9 regularly (every 10 minutes) as described above. The server 9 determines whether or not the track 5 passes in the vicinity of section 1 and section 2 based on the positional information transmitted from the track 5, and the section 3 passes through the roadside antenna 2 3 and the ETC on-board unit 25. ECU 2 7 receives ETC information (Section 3 passage information; exit information) to notify that truck 5 has passed through section 3 and has exited the EcoDrive diagnostic system service area. Is sent to the server 9 side together with the identification data and travel data.

[0025] Thus, the server 9 accumulates the traveling data periodically transmitted from the track 5 traveling in each section in this way, and when the track 5 passes through each section, the server 9 owns the track 5 itself. The fuel consumption is calculated for each section 1 to 3, but the server 9 also regularly sends travel data from many other target vehicles that are traveling on the target roads nationwide. Server 9 updates and accumulates much of the travel data sent in this way for each section of the target road for the same vehicle group. [0026] Further, although not shown in the drawing, the weather information of the target roads in the whole country is inputted to the server 9 in real time from other information sources, and the server 9 is provided for each section of the target roads in the whole country as described above. The calculated fuel economy of each current and past vehicle is accumulated by the same vehicle group under the same conditions that take the weather into consideration.

[0027] As described above, the server 9 calculates the fuel consumption for each section of the truck 5 when the truck 5 passes through each section. For example, the calculation is performed when the truck 5 passes through the section 1 in FIG. The eco-drive ranking is performed by comparing the fuel consumption of truck 5's own section 1 with the accumulated data of the same vehicle group under the same section and conditions described above, and the truck after passing the section 1 In contrast, Eco-Drive Rank information is distributed in real time.

[0028] Thus, when the eco drive rank information is distributed to the track 5, the ECU 2 7 displays the eco drive rank information on the display unit 30. Based on such eco drive rank information, the driver of truck 5 can grasp how much eco drive he is driving in his section 1 compared to other vehicles.

[0029] Hereinafter, until passing through the exit toll gate, the server 9 compares the traveling data transmitted from the track 5 with the past accumulated data every time passing through the section 2 and section 3 in the same way. Eco drive rank information is distributed in real time.

[0030] As shown in Figs. 1 and 2, the server 9 and the operation manager's terminal 37 are connected via the Internet, and the operation manager sends the eco dry blank information to the terminal 37 in the office or the like. This eco-drive rank information is published for each category on the website, so that users who plan to purchase the eco-drive diagnostic system can know on the terminal 39. The user who plans to purchase can know what kind of eco drive diagnosis system is from such eco drive rank information.

[0031] In addition, the Eco-Drive diagnostic system service according to this embodiment has many services nationwide. The same eco-drive rank information described above is distributed to many target vehicles based on the travel data transmitted on each target road, providing services. Has been.

The eco-drive diagnosis system according to the present embodiment is configured as described above. Next, the operation of the eco-drive diagnosis system will be described based on the flowchart of FIG.

First, when the track 5 is started (step S 1), the ECU 27 transmits the position information by the GPS receiver 15 and the identification data of the track 5 itself to the center 7 side by packet communication.

[0034] Thereafter, periodically (every 10 minutes), the ECU 27 uses the identification data of the truck 5 that is traveling and the traveling data (position information, fuel consumption data, traveling distance data) described above as the center 7 (Steps S 2 and 3), and on the center 7 side, the traveling data transmitted from the track 5 is sequentially input to the server 9.

[0035] Then, as shown in Fig. 1, when the truck 5 enters the toll road, which is the service target of the Eco Drive Diagnosis System, and passes through the ETC gate 17 (step S4), the ETC vehicle-mounted device 25 is connected to the roadside antenna 1 9. In this way, when ETC OBE 25 receives the entrance information, ECU 27 identifies ETC information (section 1 entry information; entrance information) that informs that truck 5 has entered section 1. Data and travel data are sent to the server 9 side.

[0036] Thereafter, track 5 traveling in section 1 periodically transmits its identification data and travel data to server 9 side (every 10 minutes) (step S5). 6) When the server 9 determines that the track 5 has passed the section 1 (near) as shown in Fig. 1 based on the position information transmitted 30 minutes after the start, the server 9 immediately proceeds to step S. Based on the travel data sent at the time of transmission of ETC information of 4 and the travel data sent 30 minutes after the start, the fuel consumption in section 1 of truck 5 is calculated, and the accumulated data of section 1 for the same vehicle group described above is calculated. The eco drive ranking is performed in comparison with (step S7), and the eco drive rank information is distributed in real time to the track 5 after passing the section 1. [0037] Thus, when the eco drive rank information is distributed to the truck 5, the ECU 27 is displayed on the display unit (the liquid crystal monitor installed on the instrument panel in the vehicle interior). By displaying the drive rank information, the driver of truck 5 can understand how much he / she drove in comparison with other vehicles in section 1 and is aware of the eco-driving in section 2 .

[0038] Hereinafter, similarly, based on the position information transmitted 40 minutes after the start (step S8), when the server 9 determines that the track 5 has passed the section 2 (near) as shown in FIG. Server 9 promptly calculates the fuel economy in section 2 of truck 5 based on the travel data sent from 30 minutes to 40 minutes after starting, and compares it with the accumulated data of section 2 in the past. (Step S 9), and Eco-drive rank information is distributed in real time to Track 5 after passing Section 2.

[0039] Thus, when the eco drive rank information is distributed to the track 5, the ECU 2 7 displays the eco drive rank information on the display unit 30. Thus, the driver In 2 you can see how much eco-driving was compared to other vehicles, and you will be aware of eco-driving in section 3.

[0040] Then, as shown in Fig. 1, the truck 5 passes through the ETC gate 21 of the exit ETC 3, and there is transmission / reception of entrance information and toll information between the roadside antenna 23 and the ETC OBE 25. The ECU 27 sends the ETC information (exit information; section 3 passage information), identification data, and travel data to the server 9 side (step S 1 0), and the server 9 starts immediately after 40 minutes. Based on the driving data up to S10, calculate the fuel consumption in section 3 of truck 5 and rank the eco-drive compared with the accumulated data of section 3 in the past (step S1 1), Distribute Eco Drive Rank information in real time to Track 5 after passing Section 3

[0041] Thus, when the eco drive rank information is delivered to the track 5, the ECU 2 7 causes the display unit 30 to display the eco drive rank information, so that the driver can display the eco drive rank information in the section 3. And be aware of future eco-driving The

[0042] Since the server 9 and the operation manager's terminal 37 are connected via the Internet as shown in Figs. 1 and 2, the operation manager sends the eco dry blank information to the terminal 37 in the office. This eco-drive rank information is published for each category on the web site. It will be possible to know what is wrong.

As described above, the eco-drive diagnosis system according to the present embodiment uses the network to obtain the travel data from the track 5 traveling in a certain section by the server 9, and the truck traveling in the section. After the server 9 compares the fuel consumption of 5 and the traveling data of the same section and the same condition accumulated by the same vehicle type group and ranks the eco drive, this eco drive rank information is tracked in real time on track 5. As a result, the driver can make real-time comparative evaluations with other vehicles according to the road conditions. As a result, the driver can be made aware of the eco-driving and improve the driving operation thereafter. Has the advantage of being connected.

[0044] And since the driver's eco-drive rank information can be obtained in real time via the Internet, the driver's efforts can be reflected in the evaluation and the fuel efficiency improvement by eco-drive This has the advantage of contributing to cost reduction.

[0045] In addition, by publishing Eco Drive rank information for each category on the website, users who plan to purchase Eco Drive Diagnosis System can know what Eco Drive Diagnosis System is, This has the advantage of helping to protect the global environment, leading to the spread of Eco Drive diagnostic systems.

[0046] In addition to the configuration of the above embodiment, for example, as in an embodiment of claim 4, the driver's own dry / one identification data is transmitted simultaneously with the traveling data from the track 5 side to the server 9 side, Server 9 stores data for the same vehicle group Based on the driver identification data, the driver's own driving data is accumulated at the same time. Based on this accumulated data, each driver's individual eco drive is ranked, and the eco drive rank information is distributed in real time. May be.

Thus, this embodiment also makes it possible for the driver to be aware of the eco-driving, and has the advantage of improving the subsequent driving operation.

[0048] Further, as in an embodiment of claim 6, for example, a parameter for ranking the eco drive is set, and the server 9 ranks the eco drive according to the parameter input from the terminal 37 of the operation manager. This may be distributed to the track 5 side.

[0049] Further, according to the parameter input from the terminal 37 of the operation manager, the server 9 travels in the same section as the vehicle A (truck 5), for example, as shown in FIG. ) If the data transition of the same section history of the vehicle A is compared with the data transition of the vehicles B to D, a good value is detected so as to be surrounded by an ellipse, It is possible to predict the possibility of abnormality.

[0050] Furthermore, in the embodiment of Fig. 1, GPS and ETC are used, but the charging system of the toll road is not limited to these, and the truck 5 and the server 9 (center 7) Although it is connected by a packet communication network, it is needless to say that other wireless transmission paths may be used.

[0051] In addition, in the embodiment of FIG. 1, when the server 9 accumulates the driving data for the same vehicle type group, the weather is taken into consideration, but other conditions such as the load capacity of the vehicle, for example, are added. If the data obtained from the target vehicle is classified and stored based on more detailed conditions, the accuracy of the EcoDrive diagnostic system will be further improved.
