  However, since the eco-driving evaluation system described in Patent Document 1 performs higher evaluation as the time for which eco-driving has been practiced is longer, for drivers who drive long distances and drivers who drive relatively low-congested roads. It can be beneficial and effective in promoting eco-driving of such drivers, but it is disadvantageous for drivers who drive only a short distance or on relatively busy roads. Such a driver may kill interest in eco-driving.

  In view of the above-mentioned points, the present invention aims to provide an eco-drive support system that supports the practice of eco-drive by more drivers, and an eco-drive support device and a privilege granting device that constitute the system. To do.

  In order to achieve the above object, the eco-drive support device according to the first invention is an eco-drive support device that supports the practice of eco-drive, and is eco-drive being performed based on the running state of the vehicle? An eco-drive determining means for determining whether or not, an eco-degree calculating means for calculating a ratio of the total driving time of the time when eco-driving is performed as an eco-degree, and an eco-degree calculated by the eco-degree calculating means are displayed. And an eco-degree display means.

  The second invention is the eco-drive support device according to the first invention, wherein the total traveling time is a time from when the ignition switch is turned on to when it is turned off.

  The third invention is an eco-drive support device according to the first or second invention, wherein the eco-drive includes an idling stop.

  By the above-described means, the present invention can provide an eco-drive support system that supports the practice of eco-drive by more drivers, and an eco-drive support device and a privilege granting device that constitute the system.

It is a block diagram which shows the structural example of the eco-drive assistance system which concerns on this invention. It is a block diagram which shows the structural example of an eco-drive assistance apparatus. It is a block diagram which shows the structural example of a privilege provision apparatus. It is a figure (the 1) which shows the structural example of a privilege table. It is FIG. (2) which shows the structural example of a privilege table. It is a flowchart which shows the flow of an eco-drive notification process. It is a flowchart which shows the flow of a privilege provision process.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration example of an eco-drive support system according to the present invention. The eco-drive support system SYS includes vehicles V1 to V3 on which the eco-drive support device 100 is mounted and the vehicles. It is comprised with the privilege provision apparatus C which performs radio | wireless communication.

  Each of the vehicles V1 to V3 is equipped with an eco-drive support device 100. The eco-drive support device 100 installed in each vehicle has an eco-degree based on the time or travel distance when the eco-drive is performed by each vehicle. And the calculated eco degree is transmitted to the privilege grant apparatus C.

  “Eco-driving” means driving that saves energy or driving to suppress the emission of carbon dioxide or air pollutants. For example, driving at economic speed, deceleration by engine brake, slow acceleration, idling stop Etc. are included. Eco-driving is a concept that includes the use of vehicles while avoiding congested roads and rush hours.

  “Eco-degree” is the percentage of the total travel time or total travel distance of the time or distance when eco-driving is performed, and the total travel time is, for example, the time from when the ignition switch is turned on until it is turned off. Thus, it is assumed that a time such as warm-up operation in which the speed is zero is also included, and the engine stop state for a short period (for example, less than 3 minutes) due to idling stop is also included in the travel time.

  The privilege granting device C is a device that receives the eco level of each vehicle transmitted by the eco-drive support device 100 and executes various processes according to the received eco level. For example, ETC (Electric Toll Collection system) Even if it is a device for collecting parking fees or highway tolls, etc., or a gasoline fee calculation device at a gas station, and an information distribution server that distributes information to each vehicle via wide area wireless communication Good.

  For example, the gasoline fee calculation device, which is the privilege granting device C, receives information on the eco level of the vehicle when the vehicle equipped with the eco-drive support device 100 enters the gas station, and the gasoline is calculated based on the received eco level. A discount rate to be applied to the rate is determined, and a gasoline rate to which the discount rate is applied is calculated.

  In this way, the eco-drive support system SYS encourages the practice of eco-drive by increasing the discount rate for vehicles with a high eco-degree.

  FIG. 2 is a block diagram illustrating a configuration example of the eco-drive support device 100 mounted on the vehicle V1. The eco-drive support device 100 includes the control device 1, the traveling state detection device 2, the navigation device 3, the communication device 4, and the storage. A device 5, an eco lamp 6 and a display device 7 are included. It is assumed that the vehicles V2 and V3 are also equipped with the same eco-drive support device 100.

  The control device 1 is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. For example, the travel information collection means 10, the eco-drive determination means 11, the eco-degree While storing programs corresponding to each of the calculating means 12 and the eco-degree display means 13 in the ROM, the CPU is caused to execute processing corresponding to each means.

  The traveling state detection device 2 is a device for detecting the traveling state of the vehicle. For example, the traveling state detection device 2 is a speed sensor, an acceleration sensor, a throttle opening sensor, a brake pressure sensor, and the like, and outputs various data to the control device 1. .

  The navigation device 3 indicates the route to the destination based on the position information (latitude, longitude, altitude) of the vehicle V1 acquired by GPS (Global Positioning System) and the map information database stored in the storage device 5. This is a system for guiding the vehicle V1.

  The communication device 4 is a device for controlling communication between the vehicle V1 and the privilege granting device C. For example, the communication device 4 is a device for controlling wireless communication using DSRC (Dedicated Short Range Communication) or a mobile phone frequency. When the request signal transmitted by the privilege granting device C is received, the eco degree notification signal is transmitted toward the privilege granting device C.

  Note that the communication device 4 may transmit the eco degree notification signal when it approaches the predetermined position without receiving the request signal, or may transmit the eco degree notification signal at a predetermined cycle. .

  The eco degree notification signal includes information on the eco degree, and may include information on a vehicle identification number, a total travel time, a total travel distance, and the like for specifying a transmission source vehicle.

  The storage device 5 is a device for storing various types of information. For example, the storage device 5 is a storage medium such as a hard disk or a DVD (Digital Versatile Disk), and includes a map information database and a travel information database 50 (hereinafter, “travel information DB 50”). And so on).

  The travel information DB 50 is a database that systematically stores information related to the travel state output by the travel state detection device 2. For example, the travel speed, acceleration, throttle opening, brake pressure, and the like are stored in a predetermined cycle (for example, every 1 second). )).

  The eco lamp 6 is a device for informing the driver that eco driving is being performed. For example, the eco lamp 6 is an LED (Light Emitting Diode) lamp installed in the instrument panel, and will be described later as eco driving determination means. Illuminates when it is determined by step 11 that eco-driving is being performed.

  In addition, the eco lamp 6 may change the emission color and brightness according to the duration of the eco drive. For example, as the duration of the eco drive becomes longer, the emission color changes such as yellow, yellow green, and green. You may make it make it.

  Further, the eco lamp 6 may emit another color (for example, red) when it is determined that the eco drive is not being executed, and the eco lamp 6 is activated depending on the duration of the eco drive not being performed. The emission color may be changed.

  The display device 7 is a device for displaying various types of information. For example, the display device 7 is a liquid crystal display attached to the navigation device 3 and displays information related to the eco level in addition to a road map and a recommended route.

  The eco lamp 6 can easily and quickly inform the driver of the current eco drive state determined based on instantaneous values such as speed, acceleration, throttle opening, brake pressure, etc., whereas the display device 7 In addition, the eco-degree calculated in more detail can be notified to the driver in consideration of other information such as road congestion, changes in vehicle speed, and air conditioner operating status.

  Next, various units included in the control device 1 will be described.

  The travel information collecting means 10 is a means for collecting travel information of the vehicle V1, for example, storing various information output from the travel state detection device 2 in the travel information DB 50 of the storage device 5 as it is, or traveling Various information output by the state detection device 2 is processed and stored in the travel information DB 50.

  For example, when the acceleration in the front-rear direction output from the acceleration sensor exceeds the threshold value T1, the travel information collection unit 10 is represented by the acceleration value or simply the fact (for example, a binary value of YES / NO). May be stored in the travel information DB 50, and when the vehicle speed output by the speed sensor falls within a certain range, the speed value or simply the fact is stored in the travel information DB 50. You may make it do.

  Further, the travel information collecting means 10 is based on the output of the navigation device 3 and the type of road on which the vehicle V1 travels (there are highways, main national roads, etc., and is preferably represented by an identification number). The traffic information may be stored in the DB 50, and the congestion level of the road on which the vehicle V <b> 1 travels is stored in the travel information DB 50 based on traffic jam information, road regulation information, event information, and the like acquired via the communication device 4. May be.

  The eco-drive determination unit 11 is a unit for determining whether or not the driving state of the vehicle is an eco-driving, for example, the speed, acceleration, throttle opening, brake pressure, etc. output by the driving state detection device 2. Based on the instantaneous value, it is determined whether or not eco-driving is currently being performed, and a control signal corresponding to the determination result is output to the eco-lamp 6.

  The eco-drive determination unit 11 may monitor the duration of the eco-drive and change the content of the control signal output to the eco-lamp 6 according to the duration. This is because the emission color of the eco lamp 6 is changed according to the duration.

  The eco-drive determination unit 11 determines whether or not the eco-drive has been performed in a predetermined period or a predetermined section while referring to the travel information stored in the travel information DB 50 by the travel information collection unit 10.

  For example, when the eco-drive determination unit 11 recognizes that the constant speed operation at the economic speed has been performed, it is assumed that the eco-drive is performed in that period or section. The economic speed is determined according to the type of road on which the vehicle V1 travels, the degree of congestion, the time zone, or weather conditions.

  In addition, the eco-drive determination unit 11 may be configured to perform eco-drive during the period or section when the acceleration when acceleration is performed at a speed lower than the predetermined speed P1 is less than the threshold value T1. The predetermined speed P1 and the threshold value T1 are also determined according to the type of road on which the vehicle V1 travels, the degree of congestion, the time zone, or weather conditions, as with the economic speed.

  Further, the eco-drive determination means 11 refers to the set temperature of the air conditioner, and if the set temperature of the air conditioner is outside the predetermined range, it is determined that the eco-drive is once performed under other conditions. However, the eco-driving may not be performed during the period or section. This is because the act of over-acting the air conditioner deteriorates the fuel consumption rate and goes against eco-driving.

  The eco degree calculation means 12 is a means for calculating the eco degree of each vehicle. For example, the eco degree calculation means 12 adds all the times or section distances determined by the eco drive determination means 11 to have been performed. The percentage of the total travel time or the total travel distance of the time or distance in which the process is performed is calculated as the eco degree.

  In addition, the eco degree calculation means 12 is, for example, a conventional rush utilization rate (a ratio of the total traveling time of a time during which the vehicle is used during a rush hour), or a traffic jam encounter rate (which is involved in a traffic jam). Etc.) may be derived, and the already calculated eco degree may be adjusted.

  For example, when the rush use rate or the traffic jam encounter rate is high, the eco degree calculation means 12 adjusts the eco degree of the vehicle to a low level, or uses the off-season use rate (use of the vehicle in a time zone other than the rush time zone). When the rate) is high, or when the highway usage rate is high, the eco level of the vehicle may be adjusted higher. This is to encourage avoiding the use of vehicles in rush hours and traffic jams.

  The eco-degree display means 13 is a means for causing the display device 7 to display the eco-degree calculated and adjusted by the eco-degree calculation means 12. A graph is displayed, or a color is distinguished (for example, the background or a partial area of the display device 7 is displayed in green, yellow, and red in descending order of eco value).

  Further, the eco degree display means 13 may display the transition of the eco degree in a graph, or may display statistical values such as the maximum value, the minimum value, and the average value so far. This is to encourage eco-driving practices.

  With the above configuration, the eco-drive support device 100 calculates and displays the eco degree as a percentage of the total travel time or the total travel distance of the eco-drive time or travel distance, so that the total travel time or total travel distance is It is possible to promote eco-driving not only by a driver of a large vehicle but also by a driver of a vehicle having a small total travel time or total travel distance.

  In addition, since the eco-drive support device 100 adjusts the eco level in consideration of the type of road to be traveled, the degree of congestion, etc., the driver who is forced to frequently use the road that is difficult to drive at the economic speed. It can also promote eco-driving.

  Next, the privilege grant apparatus C is demonstrated, referring FIG. FIG. 3 is a block diagram illustrating a configuration example of the privilege granting device C, and the privilege granting device C includes a control device C1, a communication device C2, and a storage device C3.

  The control device C1 is a computer including a CPU, a RAM, a ROM, and the like, and for example, causes the CPU to execute processing corresponding to each means while storing a program corresponding to the privilege grant means C10 in the ROM.

  The communication device C2 is a device for controlling communication between the vehicle and the privilege granting device C. For example, the communication device C2 is a device for controlling wireless communication using DSRC or mobile phone frequency, and a request signal at a predetermined cycle. And the eco level notification signal returned by the vehicle in response to the request signal is received.

  Further, the communication device C2 may receive the eco degree notification signal that the vehicle periodically transmits without transmitting the request signal.

  The storage device C3 is a device for storing various types of information. For example, the storage device C3 is a storage medium such as a hard disk or a DVD, and stores a privilege table C30 and the like. The privilege table C30 will be described later.

  The privilege granting means C10 in the control device C1 is a means for giving various benefits according to the eco level of the vehicle using the privilege granting device C. For example, the discount rate for the parking fee is set according to the eco level of the vehicle. Or a discount rate for the monthly usage fee of the information distribution server.

  When receiving the eco degree notification signal transmitted by the vehicle, the privilege granting means C10 refers to the privilege table C30 stored in the storage device C3, and extracts a discount rate corresponding to the eco degree included in the eco degree notification signal.

  The privilege grant means C10 may determine the discount rate in consideration of the total travel time, the total travel distance, etc. in addition to the eco level, and obtains the vehicle identification number included in the eco level notification signal. While managing the transition of eco-level, total travel time, total travel distance, etc. for each vehicle, the bonus content such as discount rate is determined while calculating statistical values such as monthly average travel time, annual average travel distance, etc. Also good.

  Here, the process which the privilege provision means C10 provides a privilege using the example of the privilege table C30 is demonstrated.

  The privilege table C30 is a table that represents the relationship between the eco degree calculated and adjusted by the eco degree calculating means 12 and the special award given to the vehicle that realizes the eco degree.

  4 and 5 are diagrams illustrating a configuration example of the privilege table C30. FIG. 4 illustrates a privilege table C30 included in a parking fee collection device that is an example of the privilege grant device C. FIG. 5 illustrates a privilege grant device. The privilege table C30a which the information delivery server which is another example of C has is shown.

  In FIG. 4, the privilege table C30 includes an “eco level” column, an “eco level” column, a “total travel distance” column, and a “discount rate” column.

  Here, the privilege table 30 indicates that if the eco degree is 50% or more regardless of the total travel distance, the eco level is “1” and a 3% discount on the parking fee is given.

  Further, the privilege table 30 indicates that if the total travel distance is 1000 km or more and the eco degree is 50% or more, the eco level is “2” and a 10% discount on the parking fee is given.

  The privilege grant means C10 refers to the privilege table C30, and if the eco degree is equal to or greater than a predetermined value, the discount rate of the parking fee to be granted as a privilege increases as the total travel distance increases. It is possible to promote eco-driving by enjoying drivers.

  In FIG. 5, the privilege table C30a includes an “eco level” column, an “eco degree” column, a “monthly average travel time” column, and a “discount rate” column.

  Here, in the privilege table C30a, if the average monthly travel time is 50 hours or more and less than 100 hours and the eco degree is 60% or more, the eco level is “A” and the information distribution server is used. Indicates that a 3% discount on the monthly usage fee will be granted.

  Further, the privilege table C30a indicates that the monthly average travel time is 30 hours or more and less than 50 hours, and the eco level is “B” when the eco degree is 60% or more, and the monthly fee for using the information distribution server This means that a 5% discount on the usage fee will be granted.

  The privilege grant means C10 refers to the privilege table C30a, and if the eco degree is equal to or greater than a predetermined value, the discount rate of the monthly usage fee to be granted as a privilege increases as the total travel time is shorter. It is possible to promote eco-driving by drivers who do not drive.

  With the above configuration, the eco-drive support system SYS changes the configuration of the privilege table C30 to construct a privilege grant system according to each of a variety of drivers with different driving environments, vehicle usage conditions, vehicle usage purposes, and the like. Can promote eco-driving by these diverse drivers.

  In addition, the eco-drive support system SYS can further spread the use of the information distribution server by giving a discount to the monthly usage fee of the information distribution server.

  Next, a process in which the eco-drive support device 100 informs the driver of the eco-drive state (hereinafter referred to as “eco-drive status notification process”) will be described with reference to FIG.

Eco-driving practice can be promoted by raising awareness of eco-driving.

  In addition, the eco-drive support device 100 can realize the driver's contribution to environmental protection through the eco-lamp 6 and the display device 7, or can allow the driver to practice eco-drive like a game. Can be further promoted.

  Next, with reference to FIG. 7, a process (hereinafter referred to as “privilege grant process”) in which the eco-drive support system SYS grants a privilege to a vehicle that has achieved a predetermined eco degree will be described. FIG. 7 is a flowchart showing the flow of the privilege granting process. The privilege granting device C is a parking fee collection device, and executes the privilege granting process when it receives the eco degree notification signal transmitted by the vehicle. I decided to.

  First, the privilege granting means C10 of the control device C1 in the parking fee collection device extracts and acquires the eco degree, total travel distance, and the like included in the eco degree notification signal received via the communication device C2 (step S11). .
