  Hereinafter, a drunk driving prevention system 1, a drunk driving prevention device 5, and a payment history information input device 100 according to an embodiment of the present invention will be described.

[Constitution]
FIG. 1 is a diagram illustrating an example of the overall configuration of a drunk driving prevention system 1 and a drunk driving prevention device 5. The drunk driving prevention system 1 includes a drunk driving prevention device 5 including an in-vehicle device and a user portable device, and a payment history information input device 100 installed in a restaurant or a liquor store.

  The drunk driving prevention device 5 includes, as main components mounted on the vehicle, an alcohol test device 10, an ignition switch 20, an HMI (Human Machine Interface) 30, an engine control computer 40, and a payment history information acquisition device 50. And a drunk driving prevention device ECU (Electronic Control Unit) 60. Moreover, the electronic device 70 is provided as what is carried by a user.

  The alcohol testing device 10 includes, for example, an exhalation air inlet and a test sensor. The exhalation air inlet is disposed near the driver's seat. More specifically, in a domestic vehicle where the driver's seat is on the right side of the vehicle, for example, on the right side of the steering column on the instrument panel, it is difficult to receive an inspection unless the driver's seat is seated. It is desirable to be disposed. Thereby, it is possible to increase the certainty that the driver has been inspected. The driver's exhaled air that has been blown into the exhalation port is supplied to the inspection sensor through a dedicated channel. The test sensor includes, for example, a pressure sensor and a humidity sensor for confirming that human breath has been actually blown, and an alcohol gas sensor for measuring the alcohol concentration in the breath. The output value of the inspection sensor, that is, the inspection value of the alcohol inspection device 10 is output to the drunk driving prevention device ECU 60 via an analog / digital converter or the like.

  The alcohol testing device 10 is not limited to the alcohol testing device in which the driver blows breath, and may detect and output the alcohol concentration in the saliva or blood of the driver, The alcohol concentration in the air may be detected, and this may be output as the alcohol concentration contained in the driver's breath.

  The ignition switch 20 outputs an ignition on signal as a vehicle start request signal and an ACC on signal as a vehicle system activation signal to the drunk driving prevention device ECU 60 in accordance with the vehicle start operation of the driver.

  The HMI 30 includes, for example, a display device configured as a touch panel, a speaker for sound input / output, a buzzer, and the like. The display device may be shared with the in-vehicle navigation device. The input content made to the HMI 30 is output to the drunk driving prevention device ECU 60, and the output content of the HMI 30 is determined by the drunk driving prevention device ECU 60.

  The engine control computer 40 is a computer unit in which, for example, a CPU, a ROM, a RAM, and the like are connected to each other via a bus. In addition, a semiconductor memory, an HDD (Hard Disc Drive), a DVD (Digital Versatile Disk), , I / O port, timer, counter, etc. The ROM stores programs and data executed by the CPU. The engine control computer 40 centrally controls a throttle motor, an igniter, a starter motor, a transmission, and the like. The engine control computer 40 drives the starter motor to start the engine when the ignition on signal output from the ignition switch 20 is input via the ECU 60 for drunk driving prevention device.

  The payment history information acquisition device 50 communicates with the electronic device 70 by wire or wirelessly, reads the payment history information stored in the electronic device 70, and outputs it to the drunk driving prevention device ECU 60. There is no particular limitation on the communication mode between the payment history information acquisition apparatus 50 and the electronic device 70, and any type may be used. For wireless communication, for example, Bluetooth, wireless LAN, infrared wireless, IC communication For example, a radio network of a mobile phone is used. Further, the electronic device 70 may perform wired communication by being mechanically connected, coupled, or contacted.

  The electronic device 70 is, for example, an electronic device having a payment function for shopping or eating and drinking. The configuration of the electronic device 70 may be any configuration as long as it can input and store payment history information and can output the stored payment history information to the payment history information acquisition apparatus 50. The electronic device 70 does not necessarily need to actively output payment history information by its own power supply. For example, the electronic device 70 receives electromagnetic waves of a specific frequency transmitted from the payment history information acquisition device 50 and generates power by mutual electromagnetic induction. Thus, payment history information may be transmitted.

  Specific examples of equipment that can be used as the electronic device 70 include an ETC credit card, a mobile phone with a shopping / settlement function, a smart key, and the like. Hereinafter, the case where each is used is demonstrated.

  The ETC credit card is inserted into an ETC in-vehicle device in the vehicle after paying for shopping or the like. In this case, the payment history information acquisition device 50 includes an ETC in-vehicle device. The ETC credit card records data necessary for payment of tolls and payment history information. The ETC in-vehicle device inputs / outputs information necessary for payment of tolls to / from the ETC credit card, and uses the antenna equipment to collect information on toll collection with the ETC roadside device provided at the toll gate on the toll road Send and receive. Specifically, the ID and car type of the entrance toll gate are recorded when the vehicle enters the toll road, and the ID and car type of the exit toll gate are recorded and the toll road price is settled when leaving the toll road. Etc. are performed. Further, the ETC in-vehicle device reads the payment history information from the ETC credit card and outputs it to the drunk driving prevention device ECU 60 when the vehicle system is activated (eg, when the ACC is on).

  A mobile phone to which a shopping / settlement function is added is called a so-called Osaifu-Keitai, and pays for shopping etc. by short-range wireless communication. Then, when a user (driver) carrying the vehicle gets into the vehicle and activates the vehicle system, wireless communication is performed with the payment history information acquisition device 50 (or connected to a predetermined position, or a cable is connected). The payment history information is transmitted to the payment history information acquisition device 50.

  The smart key constitutes a part of a known smart entry system, and includes a memory storing a user ID, a wireless communication device, a lithium battery, a transponder, and the like. The wireless communication device transmits a signal including the user ID and the like as a response signal to a weak radio wave (request signal) emitted by the vehicle-side transmission / reception unit. Further, when the transponder is brought close to the transmission / reception unit and receives an electromagnetic wave having a specific frequency, the transponder generates power by mutual electromagnetic induction and transmits a signal including a user ID. In this case, the payment history information acquisition device 50 includes a transmission / reception unit. The smart key includes a lock button and an unlock button, and transmits a lock signal and an unlock signal to the transmission / reception unit. When the transmission / reception unit receives the user ID, it is transmitted to a security device such as an immobilizer ECU for personal authentication to prevent theft or the like.

  In this embodiment, it is assumed that a shopping / settlement function is added to the smart key. That is, when a user (driver) who carries the shopping board enters the vehicle and activates the vehicle system after paying for shopping or the like by short-range wireless communication as in the case of the mobile phone with shopping / settlement function added Then, wireless communication is performed with the payment history information acquisition device 50 (or connected to a predetermined position or connected with a cable or the like), and the payment history information is transmitted to the payment history information acquisition device 50.

  The drunk driving prevention device ECU 60 is a computer unit having a hardware configuration similar to that of the engine control computer 40, for example. In addition, the drunk driving prevention device ECU 60 includes, as main functional blocks that function by developing (loading) a program stored in the ROM into the RAM and executing the program, a drunk estimation unit 62, a drunk state determination unit 64, And a travel restriction control unit 66. The function of each functional block will be described later.

  The payment history information input device 100 is configured based on, for example, a well-known POS (Point Of Sales) system, and includes an input device, an information processing device, a memory, a credit card terminal, a communication device, a cash drawer for cash exchange, and the like. Have. When installed in a restaurant, the input device is an order entry system including, for example, a portable data terminal and a table order terminal. When installed in an alcoholic beverage store, the input device is, for example, a bar code scanner or a touch panel for performing cash register input.

  The payment history information input device 100 inputs JAN (Japanese Article Number) code or other original information to the input device in the form of a JAN (Japanese Article Number) code and performs a predetermined operation when paying the fee. The code value is used as a search key, and the price is specified by calling the selling price from the memory. When payment is made using the electronic device 70, the information processing apparatus generates payment history information based on the provided or sold quantity of liquor included in the original information, and inputs this to the electronic device 70. Hereinafter, a specific example of payment history information will be described.

[Payment history information]
The information processing apparatus of the payment history information input device 100 generates payment history information in the form of bit information, for example, based on the original information related to eating or drinking. Bit information is, for example, a two-digit binary number indicating the payer's ability to drink, “00” indicating that there is no provision or purchase of liquor, and there is provision or purchase of liquor but the payer Is set to “10” for which drinking is unknown, “11” for which it is assumed that there is a provision or purchase of alcoholic beverages and the payer is highly likely to drink. These values are determined by applying a predetermined algorithm to the original information related to eating and drinking or shopping. For example, if five meals are provided and only one beer is provided, “10” is selected because the payer's drinking is unknown. In addition, when four meals are provided and six beers are provided, “11” is selected on the assumption that the payer may drink alcohol. It should be noted that “01” is input to the electronic device 70 as a default value when getting off.

  By making the payment history information as such simple data, it is not necessary to increase the capacity of the storage medium of the electronic device 70, thereby reducing the cost burden of the electronic device 70 and reducing the size of the electronic device 70. can do. Further, communication addition between the electronic device 70 and the payment history information input device 100 and between the electronic device 70 and the payment history information acquisition device 50 can be reduced.

  Further, in the bit information, a lower incidental bit may be set based on the type of alcoholic beverage provided or purchased. For example, assuming that the upper bit is “11”, “11-000” is selected when beer is mainly provided or purchased, and “11-001” is selected when Japanese sake is mainly provided or purchased. “11-010” is selected when wine is provided or purchased mainly, and “11-011” is selected when shochu is provided or purchased mainly, and mainly whiskey is provided or purchased In such a case, “11-100” may be selected. By doing so, it is possible to more accurately determine whether or not the driver is in a drunk state by performing detection by paying attention to the specific components of each liquor during the alcohol test in the vehicle. Become.

[Control contents of ECU 60 for drunk driving prevention device]
FIG. 2 is a flowchart showing the contents of characteristic processing executed by the drunk driving prevention device ECU 60. This flow is started, for example, when the vehicle system is started (when ACC is on).

  First, the drunk driving prevention device ECU 60 requests the payment history information acquisition device 50 to acquire payment history information (S100).

  In response to this, the payment history information acquisition device 50, for example, (1) if payment history information can be acquired, transmits this to the drunk driving prevention device ECU 60, and (2) can recognize the presence of the electronic device 70. However, even when the payment history is zero (when the bit information remains at the default value “10”), the payment history information is transmitted to the drunk driving prevention ECU 60, and (3) the presence of the electronic device 70 When it cannot recognize itself, an error signal is transmitted to ECU60 for drunk driving prevention devices.

  The drinking estimation unit 62 refers to the payment history information input from the payment history information acquisition device 50 or an error signal, and estimates whether or not the driver has drunk (S102). For example, when the bit information (the upper two digits) is “10” or “11” and when an error signal is input, it is estimated that the driver has drunk, and the bit information is “00” or “01”. It is estimated that the driver is not drinking. When the error signal is input, it is presumed that the driver has drunk because the driver does not carry the electronic device 70, so the clue of drinking can not be obtained, or even if it is carried, concealment of drinking This is because it is assumed that the power is turned off for the reason. In addition to this, the estimation method may be arbitrarily changed according to the format of payment history information. When the bit information is “10”, it may be estimated that the driver is not drinking.

  The travel restriction processing unit 66 permits the vehicle to travel when the alcohol estimation unit 62 estimates that the driver is not drinking (S104). Specifically, when an ignition on signal is input from the ignition switch 20, the ignition switch 20 is passed through and output to the engine control computer 40. Thereby, the driver can start driving at a desired timing.

  When the drinking estimation unit 62 estimates that the driver has drunk, the traveling restriction processing unit 66 restricts the traveling of the vehicle, receives a warning output using the HMI 30, and receives an alcohol test by the alcohol testing device 10. If not, a message that the vehicle is not allowed to travel is output (S106). Here, “restricting the travel of the vehicle” means, for example, that even if an ignition on signal is input from the ignition switch 20, it is not output to the engine control computer 40. In addition, the start signal is cut, the travel prohibition instruction is output to the engine control computer 40, the shift speed change prohibition instruction, the shift position is prohibited, the power supply to the starter motor is stopped, the parking brake is activated, the vehicle speed is limited, etc. May be.

  Thereafter, when an alcohol test is received by the driver, the drinking level determination unit 64 refers to the test value of the alcohol testing device 10 and determines whether or not the driver is in the drinking level (S108).

  When the drinking level determination unit 64 determines that the driver is not in the drinking state, the travel restriction processing unit 66 permits the vehicle to travel (S104). Thereby, the driver can start driving at a desired timing.

  On the other hand, when the drinking level determination unit 64 determines that the driver is in a drinking state, the travel restriction processing unit 66 continues to limit the traveling of the vehicle (S110). Thereby, the driver cannot start driving, and drunk driving is prevented in advance.

  According to the drunk driving prevention apparatus 5 of the present embodiment, an alcohol test is imposed on the driver only when it is estimated that the driver has drunk based on the payment history information (and error signal). . Therefore, it is necessary to frequently perform an alcohol test, and the inconvenience that the driver feels troublesome can be suppressed. That is, the alcohol test can be performed at an appropriate frequency, and drunk driving can be appropriately prevented.

  Moreover, you may think that the effect which the drunk driving prevention apparatus 5 show | plays as mentioned above is an effect which the drunk driving prevention system apparatus 1 implement | achieved by the drunk driving prevention apparatus 5 and the payment log | history information input device 100 show | plays.

[Modification]
The best mode for carrying out the present invention has been described above with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. And substitutions can be added.

  For example, it is also possible to store only normal payment details in the electronic device 70 without performing processing such as bit information generation in restaurants or liquor stores. In this case, the drunk driving prevention device ECU 60 directly estimates whether or not the driver has drunk from the payment details.

  Moreover, it may replace with the alcohol test | inspection apparatus 10, and you may provide the test | inspection apparatus which performs a certain driving | operation appropriateness | suitability test | inspection. Here, the driving suitability test may be something that reads something aloud or stores a number.

  Further, as shown in FIG. 3, the electronic device 70 and the payment history information input device 100 are not essential components, and the payment history information of the driver who paid by the credit card is the credit terminal 110 of the restaurant or the liquor store. To the credit company 200, which may be transmitted to the vehicle side by wireless communication via the information center 210. Here, the information center 210 is, for example, a facility that provides a paid information communication service based on a contract with a user, and is connected to a host computer or the like of the credit company 200 via the network 90.

  In this case, the payment history information acquisition device 50 is a communication device that performs wireless communication. For example, the payment history information acquisition device 50 acquires payment history information from the information center 210 via the wireless base station 80 or the network 90. Between the payment history information acquisition device 50 and the wireless base station 80, a mobile phone network, a PHS (Personal Handy-phone System) network, a wireless LAN, WiMAX (Worldwide Interoperability for Microwave Access), a satellite phone, a beacon, etc. Wireless communication is performed. The network 90 that connects the radio base station 80 and the information center 210 is a wired network such as a public switched telephone network (PSTN), a digital communication network (ISDN), or an optical fiber.

  In addition, even if it has a structure like FIG. 3, the control content of ECU60 for drunk driving prevention apparatuses demonstrated using the flowchart of FIG. 2 can be used.

  Further, as shown in FIG. 4, the payment history information of the driver who has paid with the credit card is transmitted from the credit terminal 110 of the restaurant or the liquor store to the information center 210 via the credit company 200, and based on this information. The server 220 of the information center 210 (having the same function as the drinking estimation unit 62 described above) estimates whether or not the driver has drunk, and sends the estimation result to the drunk driving prevention device mounted on the vehicle. It is good also as what to do. The nature of the information center 210 and the communication mode between the information center 210 and the vehicle may be the same as those described with reference to FIG.

  In this case, as shown in FIG. 4, the drunk driving prevention device mounted on the vehicle omits the drinking estimation unit 62 and includes a wireless communication device 52 instead of the payment history information acquisition device 50. Then, characteristic processing is executed according to the flowchart shown in FIG. This flow is also started, for example, when the vehicle system is started (when ACC is on).

  First, the drunk driving prevention device ECU 60 requests the wireless communication device 52 to connect to the information center 210 and acquire an estimation result (S200). The connection is not limited to being actively performed from the vehicle side, but may be a mode in which connection trials are periodically performed from the information center 210 and the vehicle passively receives the connection.

  Then, the drunk driving prevention device ECU 60 determines the estimation result (S202), and when the wireless communication device 52 receives the estimation result indicating that the driver is not drinking, the travel restriction processing unit 66. Permits the vehicle to travel (S204).

  When the wireless communication device 52 receives an estimation result indicating that the driver has drunk, and when the estimation result itself is not received, the travel restriction processing unit 66 restricts the traveling of the vehicle and the HMI 30 is set. The warning output and the fact that the vehicle is not permitted to run unless it receives an alcohol test by the alcohol testing device 10 are output (S206).

  Thereafter, when an alcohol test is received by the driver, the drinking level determination unit 64 refers to the test value of the alcohol testing device 10 to determine whether or not the driver is in the drinking level (S208), and determines the drinking level. When the part 64 determines that the driver is not in a drunk state, the driving of the vehicle is permitted (S204). On the other hand, if the drinking level determination unit 64 determines that the driver is in the drinking level, the driving restriction of the vehicle is continued (S210).

  Further, in the configuration illustrated in FIG. 3 or FIG. 4, a function for determining whether or not the driver is in a drinking state with reference to the test value of the alcohol testing device 10 (a function corresponding to the drinking level determination unit 64). The information center 210 may have it. In this case, the test value of the alcohol testing device 10 is transmitted to the information center 210 by wireless communication or the like, and the determination result is transmitted from the information center 210 to the vehicle. In this way, on the information center 210 side, the determination criteria / method can be flexibly changed using statistical data on the determination results, seasonal factors, and the like.

  The present invention can be used in the automobile manufacturing industry, the automobile parts manufacturing industry, and the like.
