  The present invention relates to a map information communication device and a map information communication system.

  Conventionally, navigation devices that record information corresponding to map information are known (see, for example, Patent Document 1). The navigation apparatus described in Patent Document 1 stores various information such as road section start point and end point coordinates, road type, road length, and road width in association with road identification numbers.

JP 2008-45934 A

The various information obtained by the conventional navigation device is information that can be used effectively in applications that make predictions of the vehicle state control and the vehicle state. In addition, information measured by an application may be more accurate than various types of information obtained by a conventional navigation device, or may be information that cannot be acquired by a conventional navigation device. For this reason, it is considered that a service with higher added value can be provided by sharing information by coordinating the navigation device and the application.

  Here, as an example of coordinating the navigation device and the application, various information managed on the navigation device side is transmitted to the application in association with the map information using an identifier, and the application uses the identifier to various information associated with the map information. It is conceivable to perform vehicle state control or the like related to the route scheduled to travel.

  However, the map information managed on the navigation device side may be changed with a change of the road or the like. Since current map information generally manages a predetermined position on a road with an identifier such as MAP_ID, for example, when the road is changed, the navigation device resets the road information identifier and changes the road information. The identifier may be reassigned or the number of digits of the identifier may be increased. In this way, when the road information identifier is changed, the application side cannot communicate properly unless the road information identifier is changed in the same manner as in the navigation device. In particular, when there are a plurality of applications that cooperate with the navigation device, it is necessary to change the identifier of the road information of each application.

When the recorded information is provided, communication can be performed in association with the order of the sections in the route by the second identifier that can be commonly referred to by a plurality of control processing units. That is, the first identifier allocated by the map information can be made to correspond to the second identifier determined by the route information. For this reason, even if the first identifier of the map information is changed, each application can refer to various information corresponding to the section in the route using the common second identifier. Therefore, even if the map information is changed, information associated with the map information can be communicated with each application without changing the communication method.

Here, when transmitting the record information in the route, the associating unit refers to the record information in the route expressed by the sequence of the plurality of first identifiers, and identifies the referenced record information as the second identification. It is preferred to associate with the child . The association means preferably associates the received record information with the map information by associating the second identifier with the first identifier when the record information associated with the second identifier is received. .

  With this configuration, the map information communication device associates the first identifier with the second identifier, so that each application can communicate without being aware of the change of the map information.

  The map information communication apparatus preferably includes a database that stores recording information associated with the map information by the first identifier, and learning means that updates the database based on the recording information received from the control processing unit. is there. With this configuration, it is possible to share information by cooperating the navigation device and each of the plurality of applications.

Further, the associating means may use a second identifier with a serial number. The control unit may control the vehicle. Further, the associating means creates a conversion table in which a path expressed by a sequence of a plurality of first identifiers is expressed by a sequence of second identifiers, and the first identifier and the second identifier are associated with each other. The recorded information may be associated with the map information based on the conversion table.

It is what is done.

  Initially, it demonstrates from the outline | summary of a map information communication system provided with the map information communication apparatus (map information communication part) which concerns on this embodiment. FIG. 1 is a schematic diagram illustrating an example of a map information communication system according to the present embodiment. As shown in FIG. 1, the map information communication system 5 includes a navigation ECU (Electronic Control Unit) 4 and each ECU_A (n) (n: natural number) configured to be communicable with the navigation ECU 4. Here, the ECU is a computer of an electronically controlled automobile device, and includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and an input / output interface. Yes.

The navigation ECU 4 and each ECU_A (n) are configured to be able to exchange data with each other by being connected by a CAN (Control Area Network). The ECU_A (n) has a control processing unit that performs vehicle control, vehicle state prediction, and the like based on the route information of the vehicle 3, for example, a hybrid ECU_A (1) that controls an engine, a motor, a regenerative brake, and the like. Or engine ECU_A (2) which controls engine torque etc. is used. In addition, you may use ECU which has functions, such as ACC (AdaptiveCruise Control), ABS (Antilock Brake System), PCS (Pre-Crash Safety system).

  The navigation ECU 4 includes a navigation function for performing route guidance and the like to the occupant, and includes a navigation basic unit 2, a navigation expansion unit (association unit) 1, a map DB 41, a learning DB 42, and a CAN interface 43.

  The navigation basic unit 2 has a function of detecting position information of the vehicle 3 based on a GPS satellite signal received by a GPS (Global Positioning System) receiver (not shown), for example. The navigation basic unit 2 includes a sensor unit 21, a path unit 22, and an HMI (Human Machine Interface) unit 23.

  The sensor unit 21 has a function of detecting vehicle speed and acceleration / deceleration, and a function of detecting the posture and traveling direction of the vehicle 3. The route unit 22 has a function of calculating a route from the current location to the destination, for example. The HMI unit 23 includes an interface unit through which an occupant can input, a display that informs the occupant of information, a speaker, and the like.

  The navigation basic unit 2 realizes a navigation function that is a basic function of the navigation ECU 4 by linking the functions of the above-described components.

  The map DB 41 is a database that stores map information and information associated with the map information. In the map DB 41, road information such as curve information and map information such as link information are stored in association with MAP_ID (first identifier). The MAP_ID is an identifier indicating a predetermined point on the road, and is assigned at intervals along the road. That is, when one MAP_ID is specified in the map DB 41, one map information (position, etc.) is specified. The map DB 41 has a function of reassigning the MAP_ID number from the beginning or changing the format such as carry when the road information is changed or added. The map DB 41 is configured to be referred to from the navigation basic unit 2 and the navigation extension unit 1.

The learning DB 42 is a database in which information (recording information) associated with map information by MAP_ID is stored. That is, MAP_ID is used as an identifier, and road attributes (gradients, intersections, artificial features, etc.) and vehicle states (vehicle speed, travel energy E ₁ , regenerative energy E _2, etc.) at that point are recorded. In addition, the learning DB 42 has a function of changing the MAP_ID in conjunction with the change of the MAP_ID of the map DB 41, for example. The learning DB 42 is configured to be referable and writable from the navigation basic unit 2 and the navigation extension unit 1.

  The navigation extension unit 1 realizes a cooperative function with ECU_A (n), and includes a common data management unit 11, a learning unit (learning means) 12, and a gradient conversion unit 13.

  The common data management unit 11 has a data management function for exchanging information with ECU_A (n). The common data management unit 11 has a function of assigning an identifier (second identifier) corresponding to a section in the route when communicating with ECU_A (n). This second identifier is an identifier that can be commonly referred to by a plurality of ECU_A (n). As the second identifier, for example, a route order number assigned in order for each section obtained by dividing the route in the route from the current location to the destination is used. For example, when the data stored in the map DB 41 or the learning DB 42 is transmitted to the ECU_A (n), the common data management unit 11 inputs the route of the vehicle 3 from the route unit 22, and inputs the input route to a predetermined section. It has a function of inputting information associated with the MAP_ID in each divided section from the learning DB 42 and associating the input information with the route sequence number. The common data management unit 11 has a function of outputting information associated with the path sequence number to the CAN interface 43 when transmitting information. When the data is received from the ECU_A (n), the common data management unit 11 refers to the route order number, inputs information in each section, and associates the route order number with the MAP_ID. It has a function of associating information in a section with MAP_ID. The common data management unit 11 has a function of outputting information associated with the MAP_ID to the learning unit 12 when information is received.

The gradient conversion unit 13 has a function of outputting the calculated gradient information to the learning unit 12.

  The learning unit 12 has a function of updating the learning DB 42 based on information received from the ECU_A (n). For example, when the vehicle 3 travels, the learning unit 12 has a function of storing information such as the vehicle speed received from the ECU_A (n) in the learning DB 42 or changing the stored information. Yes. In addition, it has a function of inputting gradient information from the gradient conversion unit 13 and storing or changing the stored information in the learning DB 42.

  The CAN interface 43 has a function of performing protocol conversion for communicating with ECU_A (n).

  The map information communication unit 6 includes the gradient conversion unit 13, the learning unit 12, the common data management unit 11, the map DB 41, and the learning DB 42 described above.

  Next, operation | movement of each structure of the map information communication system 5 which concerns on this embodiment is demonstrated. First, the information transmission operation of the map information communication unit 6 will be described. FIG. 2 is a flowchart showing the information transmission operation of the map information communication unit 6. The control process shown in FIG. 2 is repeatedly executed at a predetermined timing after the navigation ECU 4 is turned on, for example. In consideration of ease of understanding, a case will be described in which vehicle speed and gradient information, which is recorded information stored in the learning DB 42, is transmitted to ECU_A (m) (m: natural number, m ≦ n). The information transmission operation of the map information communication unit 6 will be described with reference to FIG. FIG. 3 is a schematic diagram for explaining the operation of the map information communication unit 6.

As shown in FIG. 2, the map information communication part 6 starts from a route information input process (S10). The process of S10 is a process executed by the navigation extension unit 1 and inputs the route information of the vehicle 3 calculated by the route unit 22. For example, as illustrated in FIG. 3A, the navigation extension unit 1 inputs route information that connects the current location P ₀ and the destination P ₁ . The route information is expressed by a combination of a plurality of MAP_IDs (arrangement of MAP_IDs). For example, when passing through points with MAP_IDs of 001, 005, 003, and 009 in this order, the current location P ₀ − 001-005-003-009- destination _{P 1} is input. When the process of S10 ends, the process proceeds to the information input process for each section (S12).

The process of S12 is a process executed by the navigation extension unit 1 and inputs vehicle speed and gradient information corresponding to the route information of the vehicle 3 input in the process of S10. For example, the navigation extension unit 1 divides the route information of the vehicle 3 input in the process of S10 into predetermined section units as shown in FIG. FIG. 3A shows an example in which one section is divided into four so that one MAP_ID corresponds to each section in consideration of easy understanding. Here, the first section, the second section, the third section, and the fourth section are set in order from the current location P ₀ to the destination P ₁ . Then, the vehicle speed and gradient information in each section are input from the learning DB 42 with reference to MAP_ID as an identifier. For example, in the first section including the point where the MAP_ID is 001, the record having the MAP_ID 001 in the learning DB 42 is referred to, and the vehicle speed and gradient information in the first section are input as 30 and 1. Similarly, the vehicle speed and gradient information for the second section, the third section, and the fourth section are input. When the process of S12 ends, the process proceeds to an identifier conversion process (S14).

The process of S <b> 14 is a process that is executed by the navigation extension unit 1 and associates the vehicle speed and gradient information of the first to fourth sections input in the process of S <b> 12 in the order of the sections of the route of the vehicle 3. The navigation expansion unit 1 inputs the identifier [n] (n: natural number) indicating the order of the route from the current location P ₀ to the destination P _{1 in} the process of S12, and the vehicle speed and gradient of each of the first to fourth segments. Correspond to information. For example, as shown in FIG. 3A, the vehicle speed and gradient 30 and 1 in the first section are associated with the identifier [1]. Similarly, the vehicle speed and gradient of each of the second section, the third section, and the fourth section are associated with the identifiers [2], [3], and [4] in the order of the route. When the process of S14 ends, the process proceeds to a transmission process (S16).

  The process of S16 is a process which the navigation expansion part 1 and the CAN interface 43 perform, and transmits the information produced | generated by the process of S14 to ECU_A (m). The navigation extension unit 1 and the CAN interface 43 transmit the vehicle speed and gradient information associated with the identifier [n] indicating the route order to the ECU_A (m). When the process of S16 ends, the control process shown in FIG. 2 ends.

  By executing the control process shown in FIG. 2, the vehicle speed and gradient information associated with the identifier [n] indicating the route order is transmitted to the ECU_A (m) as shown in FIG. 3 (A). In ECU_A (m), the vehicle speed and gradient information of the section in the route of the vehicle 3 are input with reference to the identifier [n]. As described above, when information is transmitted from the navigation ECU 4 to the ECU_A (m), the route information, the vehicle speed, and the gradient information are determined by the identifier [n] corresponding to the order of the sections in the route without using the MAP_ID assigned by the map DB 41. Can be prevented from affecting the transmission process. For example, in the conventional communication method, as shown in FIG. 8A, the vehicle speed and the gradient information are transmitted to the ECU_A (m) using MAP_ID as an identifier. In this case, as shown in FIG. 8B, when the format change is performed to change the number of digits of the MAP_ID used in the map DB 41 and the learning DB 42 from 3 digits to 4 digits, the ECU_A (m) side also Unless MAP_ID is set to 4 digits again, normal communication cannot be performed. On the other hand, even if the number of digits of MAP_ID is converted from 3 digits to 4 digits as shown in FIG. The ECU_A (m) side can receive vehicle speed and gradient information without changing the receiving method.

Next, an example in which the hybrid ECU_A (1) that has received information from the navigation ECU 4 performs vehicle control on a route from the current location P ₀ to the destination P _{2 that is} a distance L away will be described. FIG. 4A shows a route planned for traveling of the vehicle 3. FIG. 4B is a graph showing the altitude information H, travel energy E ₁ and regenerative energy E ₂ corresponding to the route of FIG. 4A, and vehicle speed V, gradient information K, travel energy E ₁ and it is a table of regenerative energy _{E 2.} Moreover, the dotted line G of the graph of FIG. 4 (B) has shown the actual topography.

The route information shown in FIG. 4A and the vehicle speed V and the gradient information K in the table shown in FIG. 4B are transmitted to the hybrid ECU_A (1) by the navigation ECU 4 executing the control process shown in FIG. Sent. Hybrid ECU_A (1), based on the vehicle speed V at each section received, calculates the travel energy E ₁ of each of sections of the route from the current position P ₀ a distance L destination P ₂ apart. Further, based on the received gradient information K, the altitude information H in each section is calculated. Then, to calculate each regenerative energy E ₂ of each section based on the altitude information H. Hybrid ECU_A (1) is calculated based on the running energy _{E 1} and regenerative energy _{E 2,} performs vehicle control to the destination _{P 2.} As described above, the hybrid ECU_A (1) can perform vehicle control using the map information corresponding to the section in the route without using the MAP_ID.

  Next, the information reception operation of the map information communication unit 6 will be described. First, the pre-processing of the information reception operation of the map information communication unit 6 according to the present embodiment will be described. FIG. 5 is a flowchart showing pre-processing of the information reception operation of the map information communication unit 6 according to the present embodiment. The control process shown in FIG. 5 is repeatedly executed at a predetermined timing after the navigation ECU 4 is turned on, for example. In consideration of ease of understanding, description will be made with reference to FIG. FIG. 7 is a schematic diagram for explaining the operation of the map information communication unit 6.

  As shown in FIG. 5, the map information communication part 6 starts from an actual travel route information input process (S30). The process of S30 is a process executed by the navigation extension unit 1 to input route information on which the vehicle 3 has actually traveled. For example, when the vehicle 3 is traveling near the point where the MAP_ID is 0001 on the traveling road shown in FIG. 7A, 0001 is input. When the processing of S30 ends, the process proceeds to identifier conversion processing (S32).

  The process of S32 is a process executed by the navigation extension unit 1 to associate the MAP_ID input in S30 with the identifier [n] corresponding to the route order. The navigation extension unit 1 associates 0001 with the identifier [1] and stores them in the table. When the process of S32 ends, the process proceeds to an identifier transmission process (S34).

  The process of S34 is a process executed by the navigation extension unit 1 and the CAN interface 43, and transmits the identifier associated with S32 to the ECU_A (m). When the process of S34 ends, the control process shown in FIG. 5 ends.

  By repeatedly executing the control process shown in FIG. 5, when the vehicle 3 travels in the order of 0001-0005-0003-0009 with MAP_ID as shown in FIG. 7A, MAP_ID0001 [1] is transmitted to ECU_A (m) and the identifier [2] corresponding to MAP_ID0005 is transmitted to ECU_A (m) while traveling through MAP_ID0005, and is associated with MAP_ID0003 while traveling through MAP_ID0003 The identifier [3] is transmitted to the ECU_A (m), and the identifier [4] corresponding to the MAP_ID0009 is transmitted to the ECU_A (m) while traveling through the MAP_ID0009. Here, it is assumed that ECU_A (m) has a function of measuring vehicle power, for example. ECU_A (m) records the measured value when the identifier [n] is received. Thereby, as shown to FIG. 7 (A), ECU_A (m) can record the measured value in each identifier [n], ie, the measured value of a path order. Then, ECU_A (m) can transmit the measured value for each identifier [n] to the navigation ECU 4.

  Next, the information reception operation of the map information communication unit 6 shown in FIG. 6 will be described. FIG. 6 is a flowchart showing the information reception operation of the map information communication unit 6 according to the present embodiment. The control process shown in FIG. 6 is repeatedly executed at a predetermined timing after the control process shown in FIG. 5 is executed, for example. In consideration of ease of understanding, description will be made with reference to FIG. FIG. 7 is a schematic diagram for explaining the operation of the map information communication unit 6.

  As shown in FIG. 6, the map information communication part 6 starts from an actual travel route information input process (S40). The process of S40 is a process that is executed by the navigation extension unit 1 and the CAN interface 43, and receives a measurement value for each identifier [n] from the ECU_A (m) via the CAN. For example, as shown in FIG. 7B, the vehicle power 20 corresponding to the identifier [1], the vehicle power 50 corresponding to the identifier [2], the vehicle power 40 corresponding to the identifier [3], and the identifier [4] The vehicle power 10 to be received is received. When the process of S40 ends, the process proceeds to an identifier conversion process (S42).

  The process of S42 is a process that is executed by the navigation extension unit 1 and associates the measured value in each identifier [n] received in the process of S40 with the MAP_ID with reference to the table generated in the process of S32 of FIG. is there. For example, as illustrated in FIG. 7B, the navigation extension unit 1 uses a table in which the identifier [n] and MAP_ID are associated with each other, the identifier [1] is MAP_ID0001, the identifier [2] is MAP_ID0005, and the identifier [3 ] Corresponds to MAP_ID0003, and identifier [1] corresponds to MAP_ID0009. When the processing of S42 ends, the process proceeds to recording processing (S44).

  The process of S44 is a process which the learning part 12 performs and records information in learning DB42. The learning unit 12 causes the learning DB 42 to reflect the vehicle power associated with the MAP_ID associated with the process of S44. When the process of S44 ends, the control process shown in FIG. 6 ends.

  By executing the control process shown in FIG. 6, the information measured by the ECU_A (m) can be reflected in the learning DB 42 without depending on the MAP_ID.

  As mentioned above, according to the map information communication part 6 and the map information communication system 5 which concern on this embodiment, with respect to several ECU_A (n) which requires the recording information linked | related with the road to the destination, several MAP_ID When providing the record information associated with the map information in the route expressed more closely, it is associated with the order of the sections in the route by the identifier [n] that can be commonly referred to by a plurality of control processing units. Can be provided. That is, the MAP_ID assigned by the map information can be associated with the identifier [n] determined by the route information. For this reason, even if the MAP_ID is changed, the ECU_A (n) side can refer to various record information corresponding to the sections in the route using the common identifier [n]. Therefore, even if the map information is changed, the record information associated with the map information can be communicated with each ECU_A (n) without changing the communication method. For this reason, the navigation ECU 4 and the plurality of ECU_A (n) can mutually improve the information accuracy, the advance prediction accuracy, and the like by mutually using the information that each has. Moreover, the versatility of the information relevant to map information can be improved.

  In addition, embodiment mentioned above shows an example of the map information communication apparatus and map information communication system which concern on this invention.
