  A computer program according to a twelfth aspect of the invention is a computer program for causing a computer to calculate an evaluation value related to energy efficiency when a vehicle travels in each section specified by a start point and an end point of a road. Based on vehicle information relating to the position of the vehicle that traveled and energy consumption, and calculating the energy efficiency of the vehicle in each of a plurality of sections of the road, and based on the calculated ratio of the energy efficiency in the two sections, A step of calculating an evaluation value relating to energy efficiency of one of the two sections.

  An evaluation value calculation method according to a thirteenth aspect of the present invention is an evaluation value calculation method by an apparatus for calculating an evaluation value related to energy efficiency when a vehicle travels in each section specified by a start point and an end point of a road. Collecting vehicle information related to the position and energy consumption of the vehicle, calculating vehicle energy efficiency in each of a plurality of sections of the road based on the collected vehicle information, and two calculated sections And calculating an evaluation value related to the energy efficiency of one of the two sections based on the ratio of the energy efficiency of the two sections.

  In the first invention, the twelfth invention and the thirteenth invention, the vehicle information collecting means collects vehicle information relating to the position and energy consumption of the vehicle traveling on the road. The vehicle information can be collected by collecting probe information (also referred to as “floating car data”) transmitted from the vehicle. The probe information identifies, for example, the position of the vehicle at a predetermined period (for example, every few seconds), the time of passing the position, the energy consumption of the vehicle (for example, fuel consumption or power consumption), and the vehicle. Includes information such as identification numbers. Moreover, when collecting vehicle information, the vehicle information which can be acquired by one driving | running | working can be collected for every vehicle, for example. When it is limited to a single run, it is possible to suppress variations such as a running state that is considered to affect the energy consumption, a vehicle-mounted amount, or a usage state of electrical components.

  The efficiency calculating means calculates the energy efficiency (for example, fuel consumption or electricity cost) of the vehicle in each of a plurality of sections (also referred to as “links”) of the road based on the collected vehicle information. The section of the road can be determined in advance and includes not only the road between the intersections but also the section between the desired start point and end point on the road. The energy efficiency is calculated by dividing the distance of the section (travel distance) by the energy consumption when traveling in the section, so that the unit fuel consumption (for example, 1 liter in the case of fuel such as gasoline) In such a case, it can be expressed by a travel distance per 1 kWh).

  The evaluation value calculation means calculates an evaluation value related to the energy efficiency of one of the two sections based on the ratio of the energy efficiency calculated in the two sections. The evaluation value related to energy efficiency is, for example, a ratio of energy consumption, and can be referred to as a fuel consumption coefficient (or electricity cost coefficient). For example, assuming that the fuel consumptions of the sections 1, 2, and 3 are a1, a2, and a3, and the section 1 is set as a reference section, the evaluation value (fuel consumption coefficient) A2 of the section 2 can be expressed by a2 / a1. The evaluation value (fuel consumption coefficient) A3 of the section 3 can be expressed by a3 / a1. As described above, the road section is divided not only between the intersections but also between desired points on the road, and the evaluation value for each section is calculated, so the fuel consumption or power consumption of the vehicle traveling on the road can be accurately calculated. Can be sought. In particular, fuel efficiency or electricity consumption is greatly affected by whether the road is uphill or downhill, so for example, sections should be set so that both uphill and downhill are not included in the road section. By setting, fuel consumption or electricity consumption can be obtained with high accuracy. In addition, since it is possible to calculate the evaluation value of the section in which the vehicle has traveled only by collecting vehicle information, there is no need to obtain fuel consumption information of each road by actual measurement, for example, by surveying or the like, and the start and end points of the road It is possible to calculate an evaluation value related to energy efficiency when the vehicle travels in each of the sections specified by.

  In the second invention, the setting means sets the reference section from among the plurality of sections of the road. A reference section (also referred to as “reference link”) is, for example, a section in a road network, and does not include an uphill and a downhill, and is flat with a small difference in height (altitude) between a start point and an end point. It can be a road. The reference section may be a section in which the energy consumption of the vehicle is actually measured, or may be a section in which the calculated energy consumption is within the reference range. The evaluation value calculation means calculates an evaluation value related to the energy efficiency of the section other than the reference section based on the ratio of the energy efficiency in the set reference section and the section other than the reference section. Thus, the evaluation values in the sections other than the reference section (also referred to as “target section” and “target link”) are calculated in a manner in contrast to the reference section, by setting only a few reference sections in advance. In addition, the evaluation value can be obtained even for the section where the evaluation value does not exist, and the evaluation value can be obtained every corner of the road network.

  In the third invention, based on the ratio of the energy efficiency between the evaluated section for which the evaluation value is calculated and the section for which the evaluation value is not calculated, the energy efficiency of the section (the section where the evaluation value is not calculated) The evaluation value for is calculated. As a result, the evaluation value can be obtained even for the section where the evaluation value does not exist, and the evaluation value can be obtained every corner of the road network.

  In the fourth invention, the storage means stores the gradient of the section associated with the evaluation value. The gradient of the section is, for example, an angle such as uphill or downhill. The gradient of the section associated with the evaluation value is, for example, divided into evaluation values (fuel consumption coefficient or power consumption coefficient) according to the magnitude of the value, and is 0 if the gradient corresponding to each classification is a flat section (flat section). 1 degree, 2 degrees for uphill sections (uphill sections), and -1 degree, -2 degrees, etc. for downhill sections (downhill sections). Can do. The specifying means specifies the gradient of the section based on the calculated evaluation value of the section. Thereby, it is possible to comprehensively grasp the gradient of each section of the road network.

  In the fifth invention, the vehicle information collecting means collects vehicle information relating to the type of vehicle. The types of vehicles (also referred to as “car classes”) can classify the types of vehicles in terms of fuel consumption or electricity costs, such as light cars, ordinary cars, and large cars. The evaluation value calculation means calculates an evaluation value of each vehicle in a section where vehicles of different types travel together. For example, it is assumed that the vehicle C1 travels in the sections 1, 2, 3, and 4 of the road R1, and the evaluation values in the sections 1, 2, 3, and 4 are A1, A2, A3, and A4. Further, it is assumed that a vehicle C2 of a type different from the vehicle C1 travels on the sections 11, 12, 3, 14 of the road R2, and the evaluation values in the sections 11, 12, 3, 14 are B11, B12, B3, B14. . Roads R1 and R2 are joined together in section 3, and section 3 is a section in which vehicles C1 and C2 traveled together.

  The type coefficient calculating means calculates a type coefficient indicating the level of energy efficiency between the types based on the ratio of the calculated evaluation values. For example, if the evaluation value of the vehicle C1 in the section 3 is A3 and the evaluation value of the vehicle C2 is B3, the type coefficient G can be calculated as G = B3 / A3, for example. Then, the evaluation value calculation means calculates the target section (section 1, section 4) based on the calculated classification coefficient G and the evaluation value of one type of vehicle (vehicle C1) calculated in the section (section 1, 2, 4). Evaluation values of other types of vehicles (vehicle C2) in 2, 4) are calculated. For example, the evaluation values B1, B2, and B4 of the vehicle C2 in the sections 1, 2, and 4 where the vehicle C2 is not traveling are obtained by B1 = G × A1, B2 = G × A2, and B4 = G × A4, respectively. Can do. Even if there is a target section where a certain type of vehicle is not traveling, by identifying the section in which different types of vehicles traveled in common and calculating the type coefficient indicating the magnitude of energy efficiency in the identified section The evaluation value in the target section of the vehicle of the type can be obtained, and the evaluation value can be obtained every corner of the road network.

  In the sixth invention, the vehicle information collecting means collects vehicle information including the speed of the vehicle. The time calculation means calculates the stop time or travel time of the vehicle in the target section. The stop time is the sum of the times during which the vehicle travels in the target section, and can be calculated by, for example, the time when the vehicle speed is equal to or lower than a predetermined speed threshold. The travel time is the time required to travel through the target section. The efficiency calculation excluding means excludes the target section from the energy efficiency calculation section when the calculated stop time is greater than a predetermined stop time threshold or when the travel time is greater than a predetermined travel time threshold. When the stop time or the travel time is larger than the respective threshold values, for example, it is considered that a traffic jam or the like has occurred. In a situation where there is a traffic jam, the running state of the vehicle also changes, which has a non-negligible effect on the fuel consumption or the power consumption. Therefore, when the stop time or the travel time is larger than the respective threshold values, the target section is excluded in order to prevent a factor that cannot be ignored in calculating the energy efficiency. As a result, the energy efficiency or the evaluation value can be calculated accurately without being affected by the traveling state of the vehicle.

  In the seventh invention, the vehicle information collecting means collects vehicle information including the acceleration of the vehicle. The efficiency calculation excluding means excludes the target section from the energy efficiency calculation section when the acceleration of the vehicle in the target section is larger than a predetermined acceleration threshold. When the acceleration of a certain vehicle is larger than a predetermined acceleration threshold value, for example, the vehicle is considered to have overtaken another vehicle. In a situation where overtaking occurs, the running state of the vehicle also changes, and the influence of the individual fuel consumption and the power consumption cannot be ignored due to individual differences in driving. Therefore, when the acceleration is larger than the threshold, the target section is excluded in order to prevent a factor that cannot be ignored from being calculated in the energy efficiency. As a result, the energy efficiency or the evaluation value can be calculated accurately without being affected by the traveling state of the vehicle.

  In the eighth invention, the evaluation value calculation excluding means excludes the target section from the evaluation value calculation section when the energy efficiency in the target section is larger than a predetermined efficiency threshold. When the energy efficiency (fuel consumption or electricity consumption) is larger than a predetermined efficiency threshold, for example, it is a downhill section or a section that does not consume fuel or electric power, and factors such as vehicle engine braking or regenerative energy are generated. Since the consumption mechanism is considered to be different from that of flat sections, uphill sections, etc., the evaluation value cannot be obtained correctly. Therefore, the evaluation value can be calculated with high accuracy by excluding the section where the energy efficiency is larger than the predetermined efficiency threshold from the evaluation value calculation section.

  In the ninth invention, the section determining means determines whether the target section is a flat section, an uphill section, or a downhill section based on the energy efficiency in the target section and a predetermined threshold. For example, when the fuel efficiency of the reference section is a, if the fuel efficiency of a certain section is within a ± 2%, the section is determined as a flat section, and if the fuel efficiency of a certain section is less than a-2%, the section is If it is determined that the vehicle is in the up section and the fuel consumption in a certain section is greater than a + 2%, the section can be determined as the down section. The predetermined threshold can be set as appropriate. By comparing energy efficiency and thresholds, if you know the fuel economy or electricity consumption in a very few reference sections in the road network, what are the other sections, ie flat sections, It is possible to determine whether a hill section or a downhill section.

  In the tenth invention, road map information is stored, and a destination is set on the road map. The route specifying means specifies the route to the destination based on the evaluation value calculated for each section from the position of the vehicle to the set destination. For example, if there are multiple routes from the starting point of the vehicle or the current point to the destination, specify the route with the highest total evaluation value (best fuel consumption or power consumption) in each section included in each route. To do. Thereby, fuel consumption (power consumption) to the destination can be predicted, and the most efficient route can be specified.

  In the eleventh invention, the vehicle information collecting means collects vehicle information relating to various amounts including the on-vehicle amount of the vehicle or the usage status of the on-vehicle product. The on-vehicle amount of the vehicle is the weight of the loaded luggage, the weight of the crew (or the number of crew), and the like. In addition, what is necessary is just to detect the vehicle-mounted quantity with the sensor etc. which were provided in the vehicle. The in-vehicle product is, for example, an electrical component, such as an air conditioner, an audio, or a headlight. The storage means stores the evaluation value and various quantities in association with each other. For example, for each section, the vehicle load is divided into several categories, a matrix is created that divides the usage status of in-vehicle products into several categories, and an evaluation value is assigned to each element of the matrix. A quantity can be associated. Note that the association between the evaluation value and various quantities can be stored for each type of vehicle.

  The various quantity acquisition means acquires various quantities of the target vehicle for specifying the route. The route specifying means specifies the route to the destination based on the evaluation value corresponding to the acquired various quantities. For example, if there are multiple routes from the starting point or the current location of the vehicle to the destination, the amount of the target vehicle in each section included in each route (mounting amount, usage status of electrical components, etc.) The route having the largest total value of the corresponding evaluation values (the best fuel efficiency or power consumption) is specified. Thereby, the most efficient route can be specified according to the state (various quantities) of the vehicle.

  According to the present invention, it is possible to calculate an evaluation value related to energy efficiency when a vehicle travels in each road section.

  Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments. FIG. 1 is a block diagram illustrating an example of the configuration of the evaluation value calculation apparatus 100 according to the present embodiment, and FIG. 2 illustrates an example of a road network that performs evaluation value calculation by the evaluation value calculation apparatus 100 according to the present embodiment. It is a schematic diagram. As shown in FIG. 1, the evaluation value calculation apparatus 100 includes a control unit 10 that controls the entire apparatus, a vehicle information acquisition unit 11, a storage unit 12, an energy efficiency calculation unit 13, a section determination unit 14, a reference section setting unit 15, The evaluation value calculating unit 16, the gradient specifying unit 17, the type coefficient calculating unit 18, the section removing unit 19, the input information acquiring unit 20, the route specifying unit 21, and the like are provided. The evaluation value calculation apparatus 100 according to the present embodiment calculates an evaluation value in an arbitrary section (also referred to as “link”) in the road network.

  First, the road section will be described. In the following description, the section is referred to as a link. As shown in FIG. 2, a plurality of roads intersect at an intersection in the road network. The link includes not only a road section between intersections but also a road section between a desired start point and an end point on a road that is not a section between intersections. In FIG. 2, the circles on the road are links. In addition, when one road is not a one-way street but a two-way street, two links can be set for one same road section according to the traveling direction of the vehicle. The link can be set in advance. Note that the position information such as the start point and end point of the link and the information such as the section distance can be stored in the storage unit 12.

  The vehicle information acquisition unit 11 has a function as vehicle information collection means, and collects vehicle information regarding the position and energy consumption of a vehicle that has traveled on the road. The vehicle information can be collected by collecting probe information (also referred to as “floating car data”) transmitted from the vehicle. The probe information identifies, for example, the position of the vehicle at a predetermined period (for example, every few seconds), the time of passing the position, the energy consumption of the vehicle (for example, fuel consumption or power consumption), and the vehicle. Includes information such as identification numbers.

  The probe information can be collected via a communication device that can communicate with an in-vehicle device mounted on the vehicle. For example, an optical beacon is installed at an appropriate position on the road network, and when the vehicle passes through a communication area with the optical beacon, the probe information is received from the in-vehicle device by the optical beacon, and the received probe information is evaluated. Transmit to the calculation device 100. Also, instead of an optical beacon, a radio communication beacon, a roadside communication device having a narrow-area communication function such as RFID or DSRC, a mid-range communication function such as a wireless LAN such as a UHF band or a VHF band, or a mobile phone, PHS, or multiple FM A communication device having a wide-area communication function such as broadcast or Internet communication may be used.

  Moreover, when collecting vehicle information, the vehicle information which can be acquired by one driving | running | working can be collected for every vehicle, for example. Here, the one-time traveling includes, for example, traveling during a day, traveling during a daytime period, traveling during a nighttime period, and the like. When it is limited to a single run, it is possible to suppress variations such as a running state that is considered to affect the energy consumption, a vehicle-mounted amount, or a usage state of electrical components.

  The storage unit 12 includes map information on the road network, information on each link (for example, information such as link start point and end point information and link distance), vehicle information collected via the vehicle information acquisition unit 11, and the like. Remember.

  The energy efficiency calculation unit 13 has a function as an efficiency calculation unit, and calculates the energy efficiency of the vehicle at each of the plurality of links on the road based on the collected vehicle information. The energy efficiency is, for example, fuel consumption or electricity consumption. That is, energy efficiency is calculated by dividing the distance of the link (travel distance) by the energy consumption (fuel consumption or power consumption) when the link travels, for example, unit fuel consumption (for example, gasoline or other fuel). In the case of 1 liter in case of electricity, or 1 kWh) in the case of electricity etc., it can be represented by a travel distance. In the following description, fuel efficiency is mainly described as energy efficiency, but the same applies to the case of electricity consumption.

  The evaluation value calculation unit 16 has a function as an evaluation value calculation unit, and based on the energy efficiency ratio of each of the two links calculated by the energy efficiency calculation unit 13, the evaluation value calculation unit 16 An evaluation value related to energy efficiency is calculated. The evaluation value related to energy efficiency is, for example, a ratio of energy consumption, and can be referred to as a fuel consumption coefficient (or electricity cost coefficient).

  FIG. 3 is an explanatory diagram illustrating an example of calculation of evaluation values by the evaluation value calculation apparatus 100 according to the present embodiment. In FIG. 3, it is assumed that links 1, 2, 3, and 4 exist on the road for simplification. In FIG. 3, it is assumed that the vehicle travels in the order of links 1, 2, 3, and 4. The vehicle may travel in the reverse direction. As shown in FIG. 3, when the fuel consumption of each of the links 1, 2, 3, 4 is a1, a2, a3, a4, and the link 1 is a reference link, the evaluation value (fuel consumption coefficient) A2 of the link 2 is , A2 / a1, the link 3 evaluation value (fuel consumption coefficient) A3 can be expressed as a3 / a1, and the link 4 evaluation value (fuel consumption coefficient) A4 can be expressed as a4 / a1. it can.

  As described above, not only the section between the intersections, but also the desired points on the road are divided by links, and the evaluation value for each link is calculated, so the fuel consumption or electricity consumption of the vehicle traveling on the road can be obtained accurately. Can do. In particular, depending on whether the road is uphill or downhill, fuel consumption or electricity consumption is greatly affected. For example, each link is set so that both the uphill and downhill are not included in the link. By setting, fuel consumption or electricity consumption can be obtained with high accuracy. In addition, since the evaluation value of the link on which the vehicle has traveled can be calculated simply by collecting the vehicle information, the fuel consumption information of each road does not need to be obtained by actual measurement by, for example, surveying, and the start and end points of the road It is possible to calculate an evaluation value related to energy efficiency when the vehicle travels on each of the links specified in (1).

  The reference section setting unit 15 has a function as a setting unit, and accepts setting of a reference link from a plurality of links on the road. The reference link (reference section) is, for example, a link in a road network, and does not include an uphill and a downhill, and is a flat road section with a small difference in height (altitude) between a start point and an end point. be able to. The reference link may be a section where the energy consumption of the vehicle is actually measured, or a section where the calculated energy consumption is within the reference range.

  Instead of the two sections, the evaluation value calculation unit 16 is based on the ratio of energy efficiency between the set reference link and a target link other than the reference link (for example, a link for which no evaluation value is calculated). An evaluation value related to the energy efficiency of the target link is calculated. As a result, it is possible to calculate the evaluation value at the target link other than the reference link in a manner in contrast to the reference link by setting only a few reference links in advance. Even in this case, the evaluation value can be obtained, and the evaluation value can be obtained for every corner of the road network.

  The evaluation value calculation unit 16 also determines the energy of the link (link for which the evaluation value is not calculated) based on the ratio of the energy efficiency between the evaluated link for which the evaluation value is calculated and the link for which the evaluation value is not calculated. An evaluation value for efficiency is calculated. As a result, the evaluation value can be obtained even for a link having no evaluation value, and the evaluation value can be obtained every corner of the road network.

  In the example described above, the type of vehicle is not particularly considered. That is, the evaluation value can be calculated as described above regardless of whether the types of vehicles are the same or different. Furthermore, the evaluation value can be calculated with high accuracy by considering the type of vehicle. Hereinafter, this point will be described.

  The vehicle information acquisition unit 11 collects vehicle information related to the type of vehicle. The types of vehicles (also referred to as “car classes”) can classify the types of vehicles in terms of fuel consumption or electricity costs, such as light cars, ordinary cars, and large cars.

  The evaluation value calculation unit 16 calculates an evaluation value (fuel consumption coefficient) of each vehicle in a section where vehicles of different types travel together.

  FIG. 4 is an explanatory diagram illustrating an example of evaluation value calculation based on different types of vehicles by the evaluation value calculation apparatus 100 according to the present embodiment. In FIG. 4, it is assumed that links 1, 2, 3, and 4 exist on the road R1, and links 11, 12, 3, and 14 exist on the road R2. That is, the roads R1 and R2 are joined together in the road section of the link 3. Then, as shown in FIG. 4, for example, when the vehicle C1 travels on the links 1, 2, 3, and 4 of the road R1, the evaluation values at the links 1, 2, 3, and 4 are A1, A2, A3, A4. Further, it is assumed that a vehicle C2 of a different type from the vehicle C1 travels on the links 11, 12, 3, and 14 of the road R2, and the evaluation values at the links 11, 12, 3, and 14 are B11, B12, B3, and B14. . The link 3 is a section in which the vehicles C1 and C2 traveled together. In this case, since the vehicle C2 is not traveling on the links 1, 2, and 4, the evaluation values on the links 1, 2, and 4 are not known.

  The type coefficient calculating unit 18 has a function as a type coefficient calculating unit, and indicates a type of energy efficiency between types based on a ratio of evaluation values of different types of vehicles calculated by the evaluation value calculating unit 16. Calculate the coefficient. For example, as shown in FIG. 4, when the evaluation value of the vehicle C1 at the link 3 is A3 and the evaluation value of the vehicle C2 is B3, the type coefficient G is calculated as G = B3 / A3, for example. be able to.

  Then, the evaluation value calculation unit 16 uses the type coefficient G calculated by the type coefficient calculation unit 18 and the vehicle of one type calculated by the target link (links 1, 2, 4 in the example of FIG. 4) (example of FIG. 4). Then, based on the evaluation value (fuel efficiency coefficient) of the vehicle C1), another type of vehicle (vehicle C2 in the example of FIG. 4) on the target link (links 1, 2, and 4 in the example of FIG. 4). The evaluation value (fuel consumption coefficient) is calculated.

  As shown in FIG. 4, the evaluation values B1, B2, and B4 of the vehicle C2 on the links 1, 2, and 4 where the vehicle C2 is not traveling are B1 = G × A1, B2 = G × A2, and B4 = G, respectively. It can obtain | require by * A4. Even if there is a target link where a certain type of vehicle does not travel, by identifying the link on which the vehicles of different types traveled in common and calculating the type coefficient indicating the energy efficiency of the identified link The evaluation value at the target link of the vehicle of the type can be obtained, and the evaluation value (fuel consumption coefficient) can be obtained every corner of the road network.

  In the example of FIG. 4, the fuel consumption coefficient (evaluation value) is obtained. However, the present invention is not limited to this, and the fuel consumption or power consumption (energy efficiency) can also be obtained. In this case, the evaluation value calculation unit 16 uses the type coefficient G calculated by the type coefficient calculation unit 18 and the vehicle of one type calculated by the target link (links 1, 2, 4 in the example of FIG. 4) (in FIG. 4). In the example, based on the energy efficiency (fuel consumption or electricity consumption) of the vehicle C1), another type of vehicle (the vehicle in the example of FIG. 4, the vehicle in the example of FIG. 4, the link 1, 2, 4). The energy efficiency (fuel consumption or electricity consumption) of C2) is calculated.

  In the above example, the evaluation value is calculated between two links or between the reference link and the target link, between the link for which the evaluation value is calculated and the link for which the evaluation value is not calculated. The link category (for example, flat link, uphill link, downhill link, etc.) can be determined before calculating the evaluation value, and the evaluation value can be calculated using the determination result. Hereinafter, this point will be described.

  First, a method for determining a link category will be described. The section determination unit 14 has a function as a section determination unit, and the link is a flat link, an uphill link, or a downhill link based on the energy efficiency (fuel consumption or power consumption) at the link and a predetermined threshold. Determine if there is.

  An uphill link is a link where the road is uphill along the traveling direction of the vehicle, and a downhill link is a link where the road is downhill along the traveling direction of the vehicle. Therefore, even in the same road section, it is an uphill link and a downhill link depending on the traveling direction of the vehicle.

  FIG. 5 is an explanatory diagram illustrating an example of determining a link category by the evaluation value calculation apparatus 100 according to the present embodiment. As shown in FIG. 5, for example, when the fuel efficiency of the reference link is a, and the fuel efficiency of a certain link (target link) is within a ± 2%, the link is determined to be a flat link. If the fuel consumption of a certain link is smaller than a-2%, the link is determined to be an uphill link. Further, when the fuel consumption of a certain link is greater than a + 2%, the link can be determined as a downhill link. The predetermined threshold can be set as appropriate. By comparing energy efficiency with thresholds and knowing the fuel efficiency or electricity costs of a few reference links in the road network, what are the other links, ie flat links, Whether the link is downhill or downhill can be determined.

  Next, a method for determining whether or not the link is a target for evaluation value calculation based on the category of the link will be described. The section removing unit 19 has a function as an evaluation value calculation excluding unit, and excludes the target link from the evaluation value calculation section when the energy efficiency (fuel consumption or power consumption) at the target link is larger than a predetermined efficiency threshold. .

  The link whose energy efficiency (fuel consumption or power consumption) is larger than a predetermined efficiency threshold is, for example, the downhill link illustrated in FIG. On downhill links, factors such as vehicle engine braking or regenerative energy are generated, so the energy consumption mechanism is considered to be different compared to flat links, uphill links, etc., so the evaluation value cannot be obtained correctly. . Therefore, the evaluation value can be calculated with high accuracy by excluding the link whose energy efficiency is larger than the predetermined efficiency threshold from the evaluation value calculation target.

  Thereby, the link for calculating the evaluation value is calculated between the uphill links, between the flat links, or between the uphill link and the flat link. Since the evaluation value is calculated between links having the same energy consumption mechanism, the evaluation value can be calculated with high accuracy.

  Instead of a configuration in which all downhill links are excluded from the evaluation value calculation target, a link that has further improved fuel efficiency over a predetermined efficiency threshold is specified as a link that does not consume fuel or power. The specified link may be excluded from the evaluation value calculation target. In this case, a downhill link that does not correspond to a link that does not consume fuel or power is an evaluation value calculation target.

  In addition, at least one of the following conditions can be supplementarily used for determining the category of the link. (1) When the link for determining the category is in the same direction as the link whose category has already been determined (that is, when the direction of the link is the same), it is determined that the category is the same as the already determined category. (2) When the link for determining the category is in the reverse direction to the link for which the category has already been determined (that is, when the direction of the link is reverse), if the already determined category is the uphill link, the link is down The link is determined to be a slope link. If the already determined category is a downhill link, the link is determined to be an uphill link. If the already determined category is a flat link, the link is determined to be a flat link. (3) When the vehicle is a hybrid vehicle or an electric vehicle, the link where the regenerative energy is generated is determined as the downhill link. (4) If the altitude difference between the starting point and the ending point of the link is greater than the threshold value by GPS positioning, it is determined that the link is an uphill link or a downhill link.

  Further, in order to calculate the evaluation value with higher accuracy, when the link satisfies the following conditions, the link can be excluded from the evaluation value calculation target.

  As the first condition, for example, the vehicle information acquisition unit 11 collects vehicle information related to a traveling state including the speed of the vehicle. The section removing unit 19 has a function as time calculation means, and calculates the stop time or travel time of the vehicle at the target link. The stop time is the sum of the times during which the target link is stopped, and can be calculated by, for example, the time when the vehicle speed is equal to or lower than a predetermined speed threshold. The travel time is the time required to pass the target link.

  The section removal unit 19 excludes the target link from the energy efficiency calculation target when the calculated stop time is greater than the predetermined stop time threshold or when the travel time is greater than the predetermined travel time threshold.

  When the stop time or the travel time is larger than the respective threshold values, for example, it is considered that a traffic jam or the like has occurred. In a situation where there is a traffic jam, the running state of the vehicle also changes, which has a non-negligible effect on the fuel consumption or the power consumption. Therefore, when the stop time or travel time is larger than the respective threshold values, the target link is excluded in order to prevent a factor that cannot be ignored from being calculated in the calculation of energy efficiency. As a result, the energy efficiency or the evaluation value can be calculated accurately without being affected by the traveling state of the vehicle.

  Note that the number of stops can be used instead of the stop time or together with the stop time. In this case, if the number of stops at the link is larger than a predetermined number threshold, the link is excluded from the energy efficiency calculation target. This is because a link that frequently stops even if the stop time is short is frequently accelerated and decelerated, and there is a high possibility that individual differences in driving will become significant.

  Next, the second condition is, for example, that the vehicle information acquisition unit 11 collects vehicle information related to a traveling state including acceleration of the vehicle. When the acceleration of the vehicle at the target link is larger than a predetermined acceleration threshold, the section removing unit 19 excludes the target link from the energy efficiency calculation target.

  When the acceleration of a certain vehicle is larger than a predetermined acceleration threshold value, for example, the vehicle is considered to have overtaken another vehicle. In a situation where overtaking occurs, the running state of the vehicle also changes, and the influence of the individual fuel consumption and the power consumption cannot be ignored due to individual differences in driving. Therefore, when the acceleration is larger than the threshold, the link is excluded in order to prevent a factor that cannot be ignored from being calculated in the energy efficiency. As a result, the energy efficiency or the evaluation value can be calculated accurately without being affected by the traveling state of the vehicle.

  Next, a method for specifying the link gradient based on the calculated evaluation value will be described. FIG. 6 is an explanatory diagram illustrating an example of a link gradient specifying method by the evaluation value calculation apparatus 100 according to the present embodiment. The storage unit 12 stores the link gradient associated with the evaluation value. The link gradient is, for example, an angle such as uphill or downhill.

  As shown in FIG. 6, for example, the evaluation value (fuel consumption coefficient or power consumption coefficient) is divided according to the magnitude of the value, and if the gradient corresponding to each division is a flat section (flat section), it is 0 degrees uphill 1 degree, 2 degrees,... For a downhill section (uphill section), and -1 degree, -2 degrees,... For a downhill section (downhill section). Is associated with the link gradient. In the example of FIG. 6, the gradient is 0 degree in the range of the fuel efficiency coefficient (A−ΔA) to (A + ΔA), and the gradient is 1 in the range of the fuel efficiency coefficient (A−2ΔA) to (A−ΔA). In the range of (A + ΔA) to (A + 2ΔA), the gradient is −1 degree.

  The gradient specifying unit 17 has a function as a specifying unit, refers to the storage unit 12 based on the calculated evaluation value at the link, and specifies the gradient associated with the evaluation value, thereby the link. Specify the slope of. Thereby, the gradient of each link of the road network can be comprehensively grasped.

  Next, the operation of the evaluation value calculation apparatus 100 of this embodiment will be described. FIG. 7 is a flowchart showing an example of an evaluation value calculation processing procedure performed by the evaluation value calculation apparatus 100 according to the present embodiment. In the following description, the subject of processing is described as the control unit 10. The control unit 10 collects vehicle information (probe information) (S11) and calculates fuel consumption at each link of the road network (S12). In the case of an electric vehicle other than a gasoline vehicle or a hybrid vehicle, the electricity cost is calculated.

  The control unit 10 sets a reference link in the road network on which the vehicle has traveled (S13). The reference link is a link that serves as a reference when calculating the fuel efficiency coefficient. For example, the reference link is a flat link in which the fuel efficiency is actually measured. In addition, as a reference | standard link, the link which many vehicles drive | worked can also be selected. That is, the required number of links can be selected as the reference link in the descending order of the number of vehicles traveling. Accordingly, it is possible to comprehensively obtain the fuel efficiency coefficients of many other links by setting a small number of reference links.

  The control unit 10 determines the category of each link (for example, flat link, uphill link, downhill link, etc.) (S14), and determines whether there is a downhill link (S15). When there is a downhill link (YES in S15), the control unit 10 excludes the downhill link from the target link for calculating the fuel efficiency coefficient (S16).

  When there is no downhill link (NO in S15), the control unit 10 performs the process of step S17 described later without performing the process of step S16. The control unit 10 calculates the fuel efficiency coefficient of the target link based on the fuel efficiency of the reference link and the target link (S17), and specifies the gradient of the target link based on the calculated fuel efficiency coefficient (S18).

  The control unit 10 determines whether or not processing has been completed for all links (S19). If the processing has not been completed (NO in S19), the processing from step S17 is continued, and processing is performed for all links. If completed (YES in S19), the process is terminated.

  The evaluation value calculation apparatus 100 can also be realized using a general-purpose computer that includes a CPU, a RAM, and the like. That is, a computer program that defines each processing procedure as shown in FIG. 7 is recorded on a recording medium such as a DVD. Then, the computer program recorded on the recording medium is read by an optical disk device or the like, and loaded into a RAM provided in the computer, and the computer program is executed by the CPU, thereby realizing an evaluation value calculation device on the computer. be able to.

  The evaluation value calculation apparatus 100 of the present embodiment can also have a route search function. In FIG. 1, an input information acquisition unit 20 has a function as destination setting means for setting a destination, and a user can set the destination.

  The route specifying unit 21 has a function as route specifying means, and based on the evaluation value calculated for each link from the position of the vehicle (for example, departure place, current location, etc.) to the set destination, Identify the path of.

  FIG. 8 is an explanatory diagram showing an example of route specification by the evaluation value calculation apparatus 100 of the present embodiment. As shown in FIG. 8, it is assumed that there are a plurality of routes from the starting point or the current point of the vehicle to the destination. In the example of FIG. 8, routes S1 and S2 exist. In this case, the route specifying unit 21 specifies the route having the largest total value of the evaluation values (fuel consumption coefficient or power consumption coefficient) in each link included in each of the routes S1 and S2 (the best fuel consumption or power consumption). For example, assuming that the total value of the fuel consumption coefficient in the route S1 is Ar1 and the total value of the fuel consumption coefficient in the route S2 is Ar2, if Ar1> Ar2, the route S1 is specified as the final route. If Ar2> Ar1, the route S2 is specified as the final route. Thereby, fuel consumption (power consumption) to the destination can be predicted, and the most efficient route can be specified.

  In addition, from the vehicle information (probe information) collected at each link for which the evaluation value is calculated, the vehicle type (vehicle class) is divided into groups according to the amount of vehicles mounted and the usage status of electrical components. The fuel consumption or power consumption, or the fuel consumption coefficient or power consumption coefficient can be stored in association with each other, and the fuel consumption or power consumption of the target vehicle can be predicted.

  In other words, the vehicle information acquisition unit 11 collects vehicle information related to various amounts including the in-vehicle amount of the vehicle or the usage status of the in-vehicle product. The on-vehicle amount of the vehicle is the weight of the loaded luggage, the weight of the crew (or the number of crew), and the like. In addition, what is necessary is just to detect the vehicle-mounted quantity with the sensor etc. which were provided in the vehicle. The in-vehicle product is, for example, an electrical component, such as an air conditioner, an audio, or a headlight.

  The storage unit 12 stores an evaluation value database in which evaluation values are associated with various quantities. FIG. 9 is a schematic diagram showing an example of the configuration of the evaluation value database of the present embodiment. As shown in FIG. 9, for each link, the in-vehicle amount is divided into several categories (20 kg in the example of FIG. 9) for each vehicle class, and the usage status of in-vehicle products (electrical components) is divided into several categories. (1 in the example of FIG. 9) a matrix is generated, and evaluation values (A11, A12,..., A21, A22,... In the example of FIG. 9) are assigned to each element of the matrix to evaluate Values and various quantities can be associated.

  The vehicle information acquisition part 11 has a function as various quantity acquisition means, and acquires various quantities of the target vehicle for specifying the route. The route specifying unit 21 specifies the evaluation value at each link by searching the evaluation value database in the storage unit 12 using the acquired quantities. Then, the route specifying unit 21 specifies the route having the largest evaluation value, for example.

  In other words, when there are multiple routes from the starting point or the current point of the vehicle to the destination, the amount of the target vehicle at each link included in each route (mounting amount, usage status of electrical components, etc.) The route having the largest total value of the corresponding evaluation values (the best fuel efficiency or power consumption) is specified. Thereby, the most efficient route can be specified according to the state (various quantities) of the vehicle.

  In addition, in the evaluation value calculation apparatus 100 of this Embodiment, the input information acquisition part 20 and the path | route identification part 21 are not essential structures. For example, the evaluation value calculated by the evaluation value calculation device 100 can be transmitted to the in-vehicle device of the vehicle, and the route can be specified by the in-vehicle device.

  As described above, according to the present embodiment, the vehicle information of the vehicle that has traveled on the road network including the reference link can be obtained by only giving the link where the fuel consumption or the power consumption is actually measured as the reference link as an initial setting. For the target link whose fuel efficiency coefficient or power cost coefficient as an evaluation value is unknown, the fuel efficiency coefficient or power cost coefficient of the target link can be calculated from the ratio of the fuel efficiency of the reference link to the fuel efficiency of the target link.

  In addition, the link for which the evaluation value (fuel efficiency coefficient or power consumption coefficient) is calculated is handled in the same way as the reference link, and the link for which the evaluation value is not calculated and the link for which the evaluation value has been calculated are used for the same trip (one run Using the vehicle information included in), the evaluation values of links for which evaluation values have not been calculated are calculated one after another based on the ratio of the fuel consumption of links for which evaluation values have not been calculated and links for which evaluation values have been calculated. Therefore, it is possible to comprehensively calculate evaluation values every corner of the road network.

  In addition, since the evaluation value of each link can be uniquely calculated regardless of the vehicle class, such as the fuel efficiency coefficient or the electricity cost coefficient, even in a link where a certain class (class) vehicle is not traveling, Since the evaluation value when the vehicle has traveled can be obtained, the fuel consumption calculation can be performed regardless of the type of the vehicle as long as the link has the calculated evaluation value.

  Further, even when there is no map information that associates the link and the gradient of the link, the fuel consumption calculation can be performed with higher accuracy than before. Further, even when various quantities of the vehicle such as the in-vehicle amount or the usage status of the electrical components change, the evaluation value based on the fuel efficiency ratio such as the fuel efficiency coefficient or the power cost coefficient is used, so that the fuel efficiency calculation can be performed.

  In addition, according to the present embodiment, it is not necessary to calculate the gradient of each road by means of actual measurement or the like for a huge number of roads that are spread throughout Japan.

  In addition, when calculating the slope of a road using statistical information such as an average value as in the past, the data used for statistics include vehicle type, fuel consumption, speed, acceleration, in-vehicle quantity, etc. Many variables are included. For this reason, in order to narrow down the variables, it is necessary to use the data of the same variable, and as a result, data of a large number of vehicles that have traveled the target link is required. could not. However, according to the present embodiment, there is no such problem.

  Further, since the fuel efficiency or the power consumption is affected by the individuality of the driver during traffic jams or before and after the vehicle stops, it is difficult to obtain the energy required for traveling from the theoretical formula. However, according to the present embodiment, the evaluation value can be calculated without using a theoretical formula.

  The disclosed embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
