It is a flowchart which shows the advertisement delivery condition determination process which the center server 10 of FIG. 1 performs. It is a flowchart which shows the process which the vehicle-mounted navigation apparatus 110 of FIG. 1 performs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing an outline of a vehicle advertisement distribution system according to an embodiment of the present invention. As shown in FIG. 1, the vehicle advertisement distribution system of this embodiment includes a center server 10 and an in-vehicle device 100. The in-vehicle device 100 is mounted on many vehicles.

  The center server 10 is installed in the information center and has a configuration capable of performing wireless communication with the communication device 102 of the in-vehicle device 100. Note that the communication here does not include broadcasting.

  From the in-vehicle device 100, vehicle information, position information, and driver information of a vehicle on which the in-vehicle device 100 is mounted are sequentially transmitted. The center server 10 receives these vehicle information, position information, and driver information from a large number of vehicles, and statistically processes the received information. Note that it is not always necessary to transmit all the vehicle information, position information, and driver information from the vehicle, and only information necessary for the hypothesis test described later may be transmitted from the vehicle.

  Furthermore, the center server 10 determines advertisement distribution conditions based on the result of statistical processing. This advertisement distribution condition determination process will be described later. The center server 10 also distributes advertisements based on advertisement distribution conditions.

  The in-vehicle device 100 includes a communication device 102 and an in-vehicle navigation device 110. The in-vehicle navigation device 110 is connected to the vehicle speed sensor 104, the brake lamp 106, and the fuel sensor 108 in addition to being connected to the communication device 102. Has been.

  The communication device 102 performs wireless communication with the center server 10 by wireless communication. The vehicle speed sensor 104 supplies a signal indicating the vehicle speed to the in-vehicle navigation device 110. The brake lamp 106 is turned on / off in conjunction with an operation of a brake pedal (not shown), and a signal indicating the on / off state is supplied to the vehicle-mounted navigation device 110. The fuel sensor 108 supplies a signal indicating the remaining fuel amount to the vehicle-mounted navigation device 110.

  The in-vehicle navigation device 110 includes a display device 112, a storage device 114, a computer 116, and an interface unit 118. Although not shown, a position detector for detecting the current position is also provided.

  Signal transmission / reception between the in-vehicle navigation device 110 and the communication device 102, the vehicle speed sensor 104, the brake lamp 106, and the fuel sensor 108 is performed via an interface unit 118. In addition, the interface unit 118 also includes other sensors in the vehicle, signals indicating the engine rotational speed Ne, accelerator opening θacc, fuel consumption, travel distance, and ignition signal (IG signal) detected and calculated by the ECU. Sequentially supplied.

  The display device 112 is disposed at a predetermined position in the passenger compartment, for example, the center console, and displays information necessary for route guidance such as a road map display. The display device 112 also functions as an advertisement notification unit in the claims, and displays an advertisement transmitted from the center server 10 to notify the vehicle driver of the advertisement. In addition, instead of the notification by display, or in addition to the notification by display, notification by voice may be performed.

  The storage device 114 stores road map data, POI (point of interest) information, an application for executing a route guidance function, and an application for executing advertisement display. The storage device 114 also stores advertisement distribution conditions transmitted from the center server 10. Further, the storage device 114 also stores driver information (for example, age, sex, etc.) and vehicle information (vehicle type, year). The driver information is input by the driver from an operation input unit (not shown).

  The computer 116 includes a CPU, a ROM, a RAM, and the like, and the CPU executes information stored in the storage device 114 to thereby detect information (vehicle information, etc.) necessary for current position detection, route guidance, advertisement display, and hypothesis testing. And so on. The application may be stored in the ROM of the computer 116.

  Next, the advertisement delivery condition determination process performed by the center server 10 will be described. FIG. 2 is a flowchart showing the advertisement distribution condition determination process. First, in step S21, a hypothesis about the driver's stopping action is set.

  This hypothesis can be set arbitrarily, but as an example here, the advertisement to be delivered is supermarket sale information, gas station price information, car wash discount campaign, convenience store sale information, car dealer vehicle sales campaign, The hypothesis set for this advertisement will be explained.

Assume that the following hypothesis is set for the above advertisement.
Hypothesis 1) Do not stop when you are in a hurry.
Hypothesis 2) When the running time exceeds a predetermined time (30 minutes in this case), it is easy to stop by.
Hypothesis 3) Stop at the gas station when the fuel level is low.
Hypothesis 4) Women in their 30s and 40s do not stop at convenience stores but stop at supermarkets.
Hypothesis 5: A driver who travels with high fuel efficiency has a high awareness of improving fuel efficiency, and is likely to drop by a car dealer's low fuel consumption vehicle sales campaign.

  In step S22, information necessary to test the significance of these hypotheses is acquired from the in-vehicle device 100 by wireless communication. Information acquired in step S22 includes vehicle information, position information, and driver information. The vehicle information includes vehicle information (engine speed, vehicle speed, accelerator opening, fuel consumption, travel distance, remaining fuel amount) that changes sequentially in addition to the information stored in the storage device 114 (that is, vehicle type and year). ) Is also included. The position information is information indicating the current longitude, latitude, and altitude. The driver information includes information indicating the age and sex of the driver. All of this information may be transmitted from the vehicle, or only information necessary for hypothesis testing may be transmitted. What information is necessary for the hypothesis test may be transmitted from the center server 10 by communication.

  In step S23, since necessary information is different for each hypothesis, the acquired information is arranged according to the hypothesis. Steps S22 and S23 are executed until the amount of information necessary for the hypothesis test can be acquired. When the amount of information necessary for the hypothesis test is acquired, step S24 is executed.

In step S24, each hypothesis set in step S21 is tested based on the information arranged in step S23. Next, this hypothesis testing method will be described in detail. For example, the following two indices are used for the hypothesis 1 test.
Index 1) If the number of accelerations or brakings is greater than α (times / minute), “Hurry up”.
Here, acceleration is measured based on the difference in speed per unit time. The number of brakes is measured from the number of times the brake lamp is lit.
(Indicator 2) If the stop is around β2 minutes or more around the POI (radius β1 (m)), “stop” is assumed. Here, the stop is detected when the vehicle speed becomes 0 km / h.

  Then, the significance of the hypothesis is tested by testing the indexes 1 and 2 by a statistical method (for example, chi-square test method). Note that the significance level in the chi-square test method is, for example, 0.05.

  In the test of Hypothesis 2, as the index 1, “traveling time exceeds 30 minutes” is used. The running time is determined by, for example, whether or not the ignition signal is off. In the test of Hypothesis 3, “low fuel remaining amount” is used as index 1. Whether the remaining amount of fuel is small is determined by whether or not the remaining amount of fuel is equal to or less than a predetermined amount. In the test of hypothesis 4, as the index 1, “the driver is a woman in their 30s and 40s” is used. Whether it is a woman in their 30s or 40s is determined from the driver information. In the test of Hypothesis 5, “the driving with good fuel efficiency” is used as the index 1. Whether or not the vehicle is traveling with good fuel efficiency is determined by whether or not the fuel efficiency transmitted as the vehicle information is the reference fuel efficiency. The reference fuel efficiency may be a constant value that does not depend on the vehicle type or model year, or may be determined according to the vehicle type or model year.

  In subsequent step S25, it is determined for each hypothesis whether or not the hypothesis is significant as a result of the test in step S24. If all hypotheses are not significant, the processing shown in FIG. Steps S24 and S25 correspond to the statistical processing means in the claims.

  On the other hand, if it is determined that at least one hypothesis is significant, that is, if at least one hypothesis is established, the process proceeds to step S26 corresponding to the advertisement delivery condition determining means in the claims, and advertisement delivery is performed based on the established hypothesis. Determine the conditions. For example, assuming that hypotheses 2, 3, and 4 are established, advertisement distribution conditions are determined from hypotheses 2, 3, and 4. In step S27, the advertisement distribution conditions determined in step S26 are transmitted to the in-vehicle device 100.

  Next, the process which the vehicle-mounted navigation apparatus 110 performs regarding an advertisement display is demonstrated. The processing shown in FIG. 3 is repeatedly executed at a predetermined repetition cycle.

  First, in step S31, it is determined whether or not advertisement distribution conditions have been received from the center server 10. If this determination is negative, the process directly proceeds to step S33. On the other hand, if the determination is affirmative, the received advertisement distribution condition is stored in the storage device 114 in step S32. Thereafter, the process proceeds to step S33.

  In step S33, it is determined whether or not the advertisement distribution condition stored in the storage device 114 is satisfied while sequentially acquiring vehicle information, position information, and driver information. If this determination is a negative determination, the processing shown in FIG.

  If the determination in step S33 is affirmative, an advertisement distribution request is transmitted to the center server 10 in step S34, which is a process corresponding to the distribution request transmission means in the claims. Upon receiving this advertisement distribution request, the center server 10 transmits an advertisement determined based on the advertisement distribution request to the in-vehicle device 100 that has transmitted the advertisement distribution request.

  Thereby, the advertisement transmitted from the center server 10 is received by the communication device 102, and the received advertisement is supplied from the communication device 102 to the vehicle-mounted navigation device 110 (step S35). The in-vehicle navigation device 110 to which the advertisement is supplied displays the advertisement on the display device 112 (step S36).

  As described above, according to the present embodiment described above, the advertisement distribution condition is determined based on the result of statistical processing of vehicle information, position information, and driver information transmitted from a large number of in-vehicle devices 100 (FIG. 2). Then, advertisement distribution is performed only for vehicles that actually satisfy the advertisement distribution conditions (FIG. 3). As a result, the driver of the vehicle that received the advertisement is likely to be interested in the advertisement, so that the advertisement can be performed effectively, and the advertisement is not distributed to vehicles that do not satisfy the advertisement distribution conditions. Costs can be reduced.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, The following embodiment is also contained in the technical scope of this invention, and also the summary other than the following is also included. Various modifications can be made without departing from the scope.

  For example, in the above-described embodiment, the advertisement distribution condition determined by the center server 10 is transmitted to the in-vehicle device 100, and the in-vehicle device 100 mounted on the vehicle determines whether or not the vehicle satisfies the advertisement distribution condition. It was. However, the present invention is not limited to this mode, and the in-vehicle device 100 may sequentially transmit vehicle information and the like to the center server 10, and the center server 10 may determine whether or not the vehicle satisfies the advertisement distribution condition. When it is determined that the vehicle satisfies the advertisement distribution condition, the center server 10 distributes the advertisement to the vehicle that satisfies the advertisement distribution condition. In this case, the center server 10 functions as the advertisement distribution means in the claims.
