Description

[Technical field]

[0001] The present invention relates to a transmission system capable of performing communication at appropriate timing according to the characteristics of, for example, a vehicle occupant. [Background technology]

[0002] Road-to-vehicle communication is known, which is communication between a roadside device installed near a road and a vehicle traveling on the road. In road-to-vehicle communication, for example, a vehicle transmits its own vehicle information to a roadside device, and the roadside device grasps the surrounding situation and transmits the information to other vehicles traveling nearby, thereby alerting the driver and preventing a collision accident. In addition, vehicle-to-vehicle communication is known, which is communication between vehicles. In vehicle-to-vehicle communication, for example, at an intersection with poor visibility, vehicles wirelessly transmit and receive their own vehicle information such as each other's position and speed, thereby alerting the driver and preventing a collision accident. In addition, in general road-to-vehicle communication and vehicle-to-vehicle communication, a vehicle can receive information such as surrounding traffic conditions and advertisements, and provide the information to the vehicle occupants.

[0003] For example, as a reference technique, Patent Document 1 discloses a technique for determining whether a vehicle driver is a novice driver or an elderly driver based on information such as the driver's date of birth. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2009-134334 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in general road-to-vehicle communication or vehicle-to-vehicle communication, for example, both the transmitting device and the receiving device are vehicles. In this case, if the occupant of one vehicle is elderly, it may take time for the occupant to understand the information provided by the other vehicle, so it is preferable to provide the information at an early timing. Thus, in road-to-vehicle communication or vehicle-to-vehicle communication, it is required to execute communication at an appropriate timing according to the characteristics of the occupants of the vehicles.

[0006] In consideration of the above problems, an object of the present invention is to provide a transmission system etc. capable of performing communication between a transmitting device and a receiving device in road-to-vehicle communication or vehicle-to-vehicle communication at an appropriate timing according to the characteristics of the vehicle occupants.

[Figure 7] FIG. 1 is a diagram illustrating an example of an information processing device that realizes a transmission system or the like in the first and second embodiments of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] <First embodiment> A transmission system 1 in the first embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a block diagram showing an example of the configuration of the transmission system 1. Fig. 2 is a flow chart for explaining an example of the operation of the transmission system 1.

[0013] The transmission system 1 includes vehicles 10A, 10B and a communication device 20. In the following description, when there is no need to distinguish between the vehicles 10A, 10B, each of the vehicles 10A, 10B will be referred to as vehicle 10 in the following description.

[0014] The vehicle 10 transmits occupant information related to the occupant of the vehicle to the communication device 20. Specifically, the vehicle 10 communicates with the communication device 20 via an on-board device provided in the vehicle 10 or a communication terminal or the like carried by the occupant in the vehicle 10.

[0015] The occupant information regarding the occupants of the vehicle is, for example, the age of the driver of the vehicle 10. In this case, the vehicle 10 transmits the age of the driver of the vehicle 10, which is registered in advance in an in-vehicle device or a communication terminal, to the communication device 20. Note that, if an imaging device such as a camera is provided inside the vehicle 10, the imaging device may capture an image of the driver's face, and the in-vehicle device or the communication terminal may analyze the captured image to determine the driver's age.

[0016] The occupant information is, for example, a score indicating an evaluation of the driving of the driver of the vehicle 10. In this case, the in-vehicle device calculates the score from the driving history of the vehicle 10 recorded in the in-vehicle device (for example, the number of sudden braking, the number of accidents, the number of sudden starts, etc.).

[0017] Furthermore, the occupant information may be, for example, the age of a passenger other than the driver of the vehicle 10. In this case, the vehicle 10 transmits the age of the passenger of the vehicle 10, which is registered in advance in an in-vehicle device or a communication terminal carried by the occupant of the vehicle 10, to the communication device 20. Note that, if an imaging device such as a camera is provided inside the vehicle 10, the imaging device may capture an image of the passenger's face, and the in-vehicle device or the communication terminal may analyze the captured image to determine the passenger's age.

[0018] The occupant information may also indicate, for example, the posture of the occupants of the vehicle 10. In this case, the vehicle 10 may capture images of the occupants of the vehicle 10 using an imaging device such as a camera inside the vehicle 10, and obtain the posture of the occupants by analyzing the captured images. In this case, the vehicle 10 transmits information indicating whether the occupants are standing or sitting, the number of standing occupants, the number of sitting occupants, etc., to the communication device 20 as the occupant information.

[0019] The occupant information may be, for example, information indicating the emotional state of the occupant of the vehicle 10. As an example, the vehicle 10 may capture an image of the occupant of the vehicle 10 using an imaging device such as a camera provided inside the vehicle 10, and an in-vehicle device or a communication terminal may analyze the captured image to obtain the emotional state of the occupant. In this case, the vehicle 10 transmits information indicating whether the occupant is feeling stress or not to the communication device 20 as the occupant information.

[0020] The occupant information may be, for example, information indicating the physical condition of the driver of the vehicle 10. As an example, the vehicle 10 may measure the body temperature of the driver of the vehicle 10 using a temperature sensor inside the vehicle 10 to obtain the physical condition of the passenger. In this case, the vehicle 10 transmits information indicating the physical condition of the driver to the communication device 20 as the occupant information.

[0021] In the above example, the occupant information is described as any one of the occupant's age, a score indicating an evaluation of driving, an indication of the occupant's posture, information indicating an emotional state, and information indicating a physical condition. The occupant information may be information related to the characteristics of the driver or information related to the characteristics of a passenger other than the driver. For example, if the occupant information is information indicating a physical condition, the occupant information may be information indicating the physical condition of the driver as described above, or information indicating the physical condition of a passenger.

[0022] The communication device 20 includes a characteristic information detection means 21, a distance detection means 22, and a communication means 23. The communication device 20 is, for example, a roadside device provided on the side of the road on which the vehicle 10 runs. The communication device 20 may also be an in-vehicle device provided in another vehicle, or may be a smartphone or the like carried by a pedestrian walking nearby. The characteristic information detection means 21, the distance detection means 22, and the communication means 23 may each be provided in a separate device.

[0023] The characteristic information detection means 21 detects characteristic information related to the characteristics of the occupants of the vehicle 10. For example, the characteristic information detection means 21 acquires occupant information related to the occupants of the vehicle as characteristic information from the vehicle 10 via the communication means 23. For example, when the age of the driver of the vehicle 10 is acquired as occupant information, the characteristic information detection means 21 may detect the age as characteristic information related to the characteristics of the occupants of the vehicle 10, or may detect ages classified into "elderly", "young", or the like as characteristic information of the occupants.

[0024] Also, for example, when a score indicating an evaluation of driving is acquired as the occupant information, the characteristic information detection means 21 may detect the score as the characteristic information of the occupant of the vehicle 10, or may detect a classification of the score into "low evaluation", "high evaluation", or the like as the characteristic information of the occupant. Note that the above-mentioned characteristic information of the occupant is merely an example, and any information other than the above characteristics may be used as long as it is information about the occupant. Similarly, the characteristic information may be any of information indicating the posture of the occupant, information indicating an emotional state, and information indicating a physical condition.

[0025] The distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than a predetermined distance set according to the characteristic information of the occupant of the vehicle 10. For example, the communication means 23 constantly transmits a response request signal to request a response to a plurality of vehicles 10 within a predetermined range. The vehicle 10 that receives the response request signal transmits a response signal including its own position information to the distance detection means 22 via the communication means 23. The vehicle 10 may further include the above-mentioned occupant information in the response signal and transmit it. The distance detection means 22 acquires the position of the communication device 20, for example, by a global positioning system (GPS) or a global navigation satellite system (GNSS). The distance detection means 22 can grasp the distance between the vehicle 10 and the communication device 20 by comparing the position information of the vehicle 10 with the position information of the communication device 20. The distance detection means 22 may acquire the position information of the vehicle 10 by analyzing an image or video captured by an imaging device such as a camera, instead of using the position information included in the response signal when acquiring the position of the vehicle 10.

[0026] Furthermore, the distance detection means 22 acquires the characteristic information of the occupants detected by the characteristic information detection means 21, and sets a distance according to the characteristic information of the occupants of each vehicle 10. Specifically, when the characteristic information of the occupants is the driver's age, the distance detection means 22 sets a longer distance to the vehicle 10 for the older occupants. On the other hand, when the characteristic information of the occupants is age, the distance detection means 22 sets a shorter distance to the vehicle 10 for the younger occupants. Furthermore, when the distance detection means 22 acquires classifications such as "elderly" and "young" as the characteristic information of the occupants, it sets a longer distance for vehicles 10 whose occupant characteristic information is classified as "elderly" than for vehicles 10 whose occupant characteristic information is classified as "young".

[0027] That is, when the age of the occupant of the vehicle 10 is a first value, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a first predetermined distance corresponding to the first value. Also, when the age of the occupant of the vehicle 10 is a second value higher than the first value, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a second predetermined distance longer than the first predetermined distance. This allows the distance detection means 22 to detect vehicles 10 with older occupants at an earlier timing than vehicles 10 with younger occupants.

[0028] Furthermore, when the occupant characteristic information is a score indicating an evaluation of driving, the distance detection means 22 sets a longer distance to the vehicle 10 as the score is lower. Furthermore, when the distance detection means 22 acquires classifications such as "low evaluation" and "high evaluation" as the occupant characteristic information, it sets a longer distance for vehicles 10 whose occupant characteristic information is classified as "low evaluation" than a distance for vehicles 10 whose occupant characteristic information is classified as "high evaluation".

[0029] That is, when the value indicating the evaluation of the occupant of the vehicle 10 on the driving is a first value, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a first predetermined distance set according to the first value. Furthermore, when the value indicating the evaluation of the occupant of the vehicle 10 on the driving is a second value smaller than the first value, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a second predetermined distance longer than the first predetermined distance. This allows the distance detection means 22 to detect vehicles 10 carrying occupants with low driving evaluations at an earlier timing than vehicles 10 carrying occupants with high driving evaluations.

[0030] Also, assume that the occupant characteristic information indicates the age of a passenger other than the driver of the vehicle 10. In this case, the distance detection means 22 sets a long distance to the vehicle 10 when the passenger's age is less than the threshold. That is, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is less than a first predetermined distance when the passenger's age is equal to or greater than the threshold. Also, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is less than a second predetermined distance that is longer than the first predetermined distance when the passenger's age is less than the threshold. This allows the distance detection means 22 to detect a vehicle 10 with a child or the like on board at an earlier timing than other vehicles 10.

[0031] Also, assume that the characteristic information of the occupants indicates the posture of the passengers in the vehicle 10. For example, the distance detection means 22 sets a longer distance to the vehicle 10 as the number of standing passengers increases. Also, when the distance detection means 22 acquires information indicating that the number of standing passengers exceeds a threshold as characteristic information, it sets the distance to the vehicle 10 longer than the distance to the other vehicles 10. That is, when the number of standing passengers in the vehicle 10 is less than the threshold, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a first predetermined distance. Also, when the number of standing passengers in the vehicle 10 is equal to or greater than the threshold, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a second predetermined distance that is longer than the first predetermined distance. As a result, the distance detection means 22 can detect a vehicle 10 with many standing passengers at an earlier timing than a vehicle 10 with few standing passengers.

[0032] In addition, when the occupant characteristic information is information indicating the emotional state of the driver, the distance detection means 22 sets a longer distance to the vehicle 10 as the emotional state indicates a higher stress state. In addition, when the distance detection means 22 acquires classifications such as "stress state" and "stable state" as the occupant characteristic information, the distance detection means 22 sets the distance to the vehicle 10 for which the occupant characteristic information is classified as "stress state" longer than the distance to the vehicle 10 for which the occupant characteristic information is classified as "stable state". That is, when the characteristic information according to the emotional state indicates a stable state, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a first predetermined distance set according to the stable state. In addition, when the characteristic information according to the emotional state indicates a stress state, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a second predetermined distance longer than the first predetermined distance. As a result, the distance detection means 22 can detect the vehicle 10 driven by a driver in a stress state at an earlier timing than the vehicle 10 driven by a driver in a stable state.

[0033] In addition, when the occupant characteristic information is information indicating the physical condition of the driver, the distance detection means 22 sets a longer distance to the vehicle 10 as the physical condition of the driver becomes poorer. In addition, when the distance detection means 22 acquires classifications such as "health condition" and "ill health condition" as the occupant characteristic information, the distance detection means 22 sets the distance to the vehicle 10 in which the occupant characteristic information is classified as "ill health condition" longer than the distance to the vehicle 10 in which the occupant characteristic information is classified as "health condition". In other words, when the occupant characteristic information indicates the physical condition of the driver, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or shorter than a second predetermined distance that is longer than the first predetermined distance set according to the "health condition" when the occupant characteristic information indicates the "ill health condition". As a result, the distance detection means 22 can detect the vehicle 10 driven by a driver in an unwell state at an earlier timing than the vehicle 10 driven by a driver in a healthy state.

[0034] When the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than a predetermined distance, one of the vehicle 10 and the communication device 20 transmits information to the other of the vehicle 10 and the communication device 20.

[0035] For example, when a vehicle 10 is detected by the distance detection means 22, the communication means 23 transmits information, etc., directed to the occupants, to the detected vehicle 10. Also, for example, when a vehicle 10 is detected by the distance detection means 22, the vehicle 10 receives a notification from the distance detection means 22 via the communication means 23, and transmits information regarding the vehicle, occupants, etc. to the communication means 23.

[0036] In addition, the information transmitted by the communication means 23 or the vehicle 10 indicates, for example, the state of traffic lights in the vicinity of the communication device 20 or the vehicle 10, the approach of an emergency vehicle such as an ambulance, advertisements from nearby stores, driving assistance messages, alerts, etc.

[0037] For example, the communication means 23 transmits information selected based on characteristic information of the occupant of the vehicle 10 to the vehicle 10. For example, data indicating advertisements classified as "for young people" and data indicating advertisements classified as "for elderly people" are input to the communication means 23 from an external communication device. When the characteristic information of the occupant of the vehicle 10 is "young people", the communication means 23 selects data indicating advertisements classified as "for young people" from the input data and transmits it to the vehicle 10.

[0038] Furthermore, for example, the distance detection means 22 detects at an early stage a vehicle 10 with a passenger whose driving is poorly evaluated, and the vehicle 10 can notify at an early stage the communication device 20, which may be an in-vehicle device of another vehicle, a roadside device, or a smartphone carried by a pedestrian, that the driving of the vehicle 10 is unstable. This allows drivers of other vehicles and pedestrians to know in advance that a vehicle 10 with unstable driving is driving nearby, and to take action in sufficient time.

[0039] Similarly, drivers of other vehicles, roadside devices and pedestrians can be aware in advance that a vehicle 10 with a small child on board, a vehicle 10 with many standing passengers, a vehicle 10 driven by a stressed driver or a vehicle 10 driven by a driver in an ill state is traveling nearby and can respond in sufficient time.

[0040] Furthermore, if the driver of the vehicle 10 is elderly, the driver of the vehicle 10 can, for example, be aware of surrounding traffic conditions, advertisements, and the like in advance from the communication device 20, and can respond in sufficient time.

[0041] For communication between the communication means 23 and the vehicle 10, vehicle-to-vehicle communication or road-to-vehicle communication technologies such as DSRC (Dedicated Short Range Communications), C-V2X (Cellular-V2X (Vehicle-to-Everything)), and NR-V2X (NewRadio-V2X (Vehicle-to-Everything)), cellular communication technologies such as LTE (Long Term Evolution) and 5G (Gneration), and wireless communication technologies such as WiFi (registered trademark) are used.

[0042] Next, the operation of the transmission system 1 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 shows an example of a range according to characteristic information of an occupant of the vehicle 10 and a positional relationship with the vehicle 10 in the transmission system 1. In the transmission system 1 in Fig. 2, it is assumed that "young people" and "elderly people" are set as characteristic information of the occupant.

[0043] 2, in the transmission system 1, a predetermined distance A is set around the communication device 20, or a predetermined distance B shorter than the predetermined distance A is set. The predetermined distance A is a distance associated with the occupant characteristic information of "elderly." The predetermined distance B is a distance associated with the occupant characteristic information of "young."

[0044] In the example shown in FIG. 2, the vehicle 10A is located within the range A corresponding to the predetermined distance A corresponding to the characteristic information of the occupant of the vehicle 10A, that is, "elderly". Therefore, the distance detection means 22 determines that the distance between the vehicle 10A and the communication device 20 is equal to or less than the predetermined distance A, and the communication means 23 transmits information to be provided to the occupant of the vehicle 10A to the vehicle 10A. On the other hand, the vehicle 10B is located within the range A corresponding to the predetermined distance A corresponding to the characteristic information of "elderly", but is not located within the range B corresponding to the predetermined distance B corresponding to the characteristic information of the occupant of the vehicle 10B, that is, "young". Therefore, the distance detection means 22 does not determine that the distance between the vehicle 10B and the communication device 20 is equal to or less than the predetermined distance B, and the communication means 23 does not transmit information to be provided to the occupant of the vehicle 10B to the vehicle 10B. Note that when the vehicle 10B moves to a position within the predetermined distance B from the communication device 20, the distance detection means 22 determines that the vehicle 10B is located within the predetermined distance, and the communication means 23 transmits information to be provided to the occupant of the vehicle 10B to the vehicle 10B. In the above description, the communication means 23 transmits information to the vehicle 10. However, the vehicle 10 may transmit information to the communication means 23.

[0045] Next, the operation flow of the transmission system 1 will be described with reference to FIG.

[0046] The communication means 23 transmits a response request signal to vehicles within a predetermined range (S101). In response to receiving the response request signal, the vehicle 10A transmits a response signal (S102). In this operation flow, the response signal includes occupant information related to the occupant of the vehicle 10A and location information indicating the location of the vehicle 10.

[0047] The communication means 23 receives the response signal and outputs the occupant information to the characteristic information detection means 21 (S103). The characteristic information detection means 21 detects characteristic information related to the characteristics of the occupant (S104). For example, when the characteristic information detection means 21 acquires a classification of "elderly" from the communication means 23, it detects "elderly" as the characteristic information of the occupant. Also, for example, when the characteristic information detection means 21 acquires the age of the occupant from the communication means 23, it may detect the age as the characteristic information of the occupant, or may detect "elderly" as the characteristic information of the occupant based on the age. Also, the characteristic information of the occupant may be any of the multiple examples described above.

[0048] The characteristic information detection means 21 outputs the characteristic information of the occupant to the distance detection means 22 (S105). The distance detection means 22 specifies the distance according to the characteristic information of the occupant (S106). For example, the distance detection means 22 acquires in advance a table that stores the correspondence between the characteristic information and the distance, and specifies the predetermined distance according to the characteristic information by referring to the table.

[0049] The communication means 23 outputs the position information of the vehicle 10A included in the response signal received from the vehicle 10A to the distance detection means 22 (S107). Note that the communication means 23 may continuously acquire the position information of the vehicle 10A by repeating communication with the vehicle 10A other than the processes of S101 and S102, and output the position information to the distance detection means 22. Note that the distance detection means 22 may acquire the position information of the vehicle 10 by analyzing an image or video captured by an imaging device such as a camera, rather than using the position information included in the response signal when acquiring the position of the vehicle 10.

[0050] The distance detection means 22 detects that the distance between the vehicle 10A and the communication device 20 is equal to or less than the predetermined distance specified in S108 (S108). Specifically, the distance detection means 22 compares the position information of the vehicle 10A acquired from the communication means 23 with the position information of the communication device 20, and detects that the distance between the vehicle 10A and the communication device 20 is equal to or less than the predetermined distance specified in S106. On the other hand, if the distance detection means 22 does not detect that the distance between the vehicle 10A and the communication device 20 is equal to or less than the predetermined distance specified in S106, it performs S108 every time it acquires new position information of the vehicle 10A from the communication means 23.

[0051] The distance detection means 22 notifies the communication means 23 that the vehicle 10A is located within a predetermined distance (S109). The communication means 23 transmits information, for example, to the occupants of the vehicle 10A (S110). The provided information transmitted by the communication means 23 indicates, for example, the state of lights of traffic lights near the communication device 20, the approach of an emergency vehicle such as an ambulance, advertisements from nearby stores, and the like.

[0052] Next, a modified example of the operation of the transmission system 1 will be described with reference to Fig. 4. As shown in Fig. 4, the modified example of the transmission system 1 performs the processes of S101 to S109 in the same manner as described above. In the modified example, the communication means 23 further notifies the vehicle 10A that the distance between the communication device 20 and the vehicle 10A is equal to or less than a predetermined distance (S110A). The vehicle 10A that receives the notification transmits information related to the vehicle, occupants, etc. to the communication means 23 (S111A).

[0053] As described above, in the transmission system 1, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than the predetermined distance set according to the characteristic information of the occupant of the vehicle 10. In addition, when the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than the predetermined distance, one of the vehicle 10 and the communication device 20 transmits information to the other of the vehicle 10 and the communication device 20. The communication means 23 corresponds to the transmission means. Therefore, for example, by setting a wider range according to the characteristic information of the occupant of the vehicle 10 as the occupant of the vehicle 10 is older, the distance detection means 22 can detect that the vehicle 10 is located within the predetermined distance according to the characteristic information at an earlier timing. As a result, the communication means 23 can transmit the provided information at an earlier timing as the occupant of the vehicle 10 is older. In this way, according to the transmission system 1, communication between the transmission device and the reception device in road-to-vehicle communication or vehicle-to-vehicle communication can be performed at an appropriate timing according to the characteristics of the occupant of the vehicle.

[0054] Generally, the older a person is, the slower they tend to react after receiving information. Therefore, in the transmission system 1, for example, the older the occupant of the vehicle 10 is, the earlier the information to be provided is transmitted, so that the elderly can receive the information at an early stage. As a result, the elderly can respond to the received information with ample time. For example, an elderly occupant can quickly learn of the presence of a dangerous vehicle or the like nearby, so that the occupant can take appropriate action and prevent accidents, etc. <Second embodiment> A transmission system 2 according to the second embodiment will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is a block diagram showing an example of the configuration of the transmission system 2. Fig. 6 is a flowchart showing an example of the operation of the transmission system 2.

[0055] 5, the transmission system 2 includes a communication device 20 having a characteristic information detection means 21, a distance detection means 22, and a transmission means 24, and a vehicle 10. The characteristic information detection means 21, the distance detection means 22, and the transmission means 24 of the transmission system 2 may have the same functions and connection relationships as the characteristic information detection means 21, the distance detection means 22, and the transmission means 24 of the transmission system 1.

[0056] The characteristic information detection means 21 detects characteristic information related to the characteristics of the occupant of the vehicle 10. The distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than a predetermined distance set according to the characteristic information of the occupant. In addition, when the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than the predetermined distance, one of the vehicle 10 and the communication device 20 (transmission means 24) transmits information to the other of the vehicle 10 and the communication device 20.

[0057] Next, an example of the operation of the transmission system 2 will be described with reference to FIG.

[0058] The characteristic information detection means 21 detects characteristic information of a vehicle occupant (S201). The distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than a predetermined distance set according to the characteristic information of the occupant (S202). One of the vehicle 10 and the communication device 20 (transmission means 24) transmits information to the other of the vehicle 10 and the communication device 20 (S203).

[0059] As described above, in the transmission system 2, the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than the predetermined distance set according to the characteristic information of the occupant of the vehicle 10. In addition, when the distance detection means 22 detects that the distance between the vehicle 10 and the communication device 20 is equal to or less than the predetermined distance, one of the vehicle 10 and the communication device 20 transmits information to the other of the vehicle 10 and the communication device 20. The communication means 23 corresponds to the transmission means. Therefore, for example, by setting a wider range according to the characteristic information of the occupant of the vehicle 10 as the occupant of the vehicle 10 is older, the distance detection means 22 can detect that the vehicle 10 is located within the predetermined distance according to the characteristic information at an earlier timing. As a result, the communication means 23 can transmit the provided information at an earlier timing as the occupant of the vehicle 10 is older. In this way, according to the transmission system 2, communication between the transmission device and the reception device in road-to-vehicle communication or vehicle-to-vehicle communication can be performed at an appropriate timing according to the characteristics of the occupant of the vehicle.

[0060] Generally, the older a person is, the slower they tend to react after receiving information. Therefore, in the transmission system 1, the older the occupant of the vehicle 10 is, the earlier the information to be provided is transmitted, so that the elderly can receive the information at an early stage. As a result, the elderly can respond to the received information with ample time. For example, an elderly occupant can quickly learn of the presence of a dangerous vehicle nearby, and therefore can take appropriate action to prevent accidents, etc.

[0063] There are various variations in the method of realizing each device. For example, each device may be realized by any combination of a separate information processing device 2000 and a program for each component. Also, multiple components included in each device may be realized by any combination of a single information processing device 2000 and a program.

[0064] In addition, a part or all of each component of each device may be realized by a general-purpose or dedicated circuit including a processor, etc., or a combination of these. These may be configured by a single chip, or may be configured by multiple chips connected via a bus. A part or all of each component of each device may be realized by a combination of the above-mentioned circuits, etc., and a program.

For example, each of the information processing devices, circuits, etc. may be realized in a form connected via a communication network.
