Description

  The present invention relates to a driving tendency totaling system, a vehicle information providing apparatus, and a driving tendency totaling apparatus, and in particular, a driving tendency totaling system suitable for preventing, for example, a drunk driving of a vehicle driver or suppressing the drinking itself. The present invention relates to a vehicle information providing device and a driving tendency totaling device.

Conventionally, the alcohol concentration in the breath of the vehicle driver is detected, and if the alcohol concentration is less than a specified value as a result of the detection, the driver is allowed to drive the vehicle as normal because the driver is not in a drinking state. In the case where the alcohol concentration is equal to or higher than a specified value, a technique is known in which the driver is in a drinking state and the vehicle engine is stopped to restrict the driving (see, for example, Patent Document 1). According to such a technique, when the vehicle driver is in a drunk state, driving of the vehicle becomes impossible, so that drunk driving of the vehicle is prevented and the safe driving is surely realized. In this technique, when it is determined that the driver is in a drinking state, the position information of the vehicle is reported to an external organization such as the police or the center.
JP 2004-318411 A

  By the way, after it is determined that the person who is driving is in a drinking state and driving of the vehicle is prohibited, the person who actually drives tries to lift the driving prohibition, and the driver impersonates a person who is not that person and drinks It may be misjudged if it is not in a state. In this case, the driving prohibition of the vehicle is canceled and the driving is permitted because the driver is not in a drinking state, and the person who has drunk can drive the vehicle.

  In this regard, even if only the location information of the vehicle is reported to an external organization when it is determined that the driver is in a drinking state as in the technology described above, the person who drank the vehicle is free to drive without restriction. Therefore, it is difficult to effectively and appropriately prevent the drunk driving of the vehicle.

  In addition, the above-described technique only reports only the position information of the vehicle detected after the driver's drinking detection, and therefore does not effectively suppress the drinking itself before the driver's drinking.

  The present invention has been made in view of the above points, and is a driving tendency counting system capable of specifying an effective road in preventing drunk driving of a vehicle driver or deterring drunk itself, An object is to provide a vehicle information providing device and a driving tendency totaling device.

  The purpose of the above is that when the vehicle prohibition state once performed when the vehicle driver is in a drunk state is canceled because the vehicle driver is not in a drunk state, the vehicle is subsequently moved within a predetermined period. There is a risk of drunk driving based on a travel trajectory measuring unit that measures a travel trajectory traveled, an information totaling unit that tabulates information on the travel trajectory measured by the travel trajectory measuring unit, and a totaling result obtained by the information totaling unit. This is achieved by a driving tendency totaling system having road extraction means for extracting a road on which a certain vehicle is easy to pass.

  In this aspect of the invention, once the driving prohibition is canceled because the vehicle driver is not in the drinking state after the driving is temporarily prohibited due to the drinking state of the vehicle driver, the driving prohibition state is subsequently released for a predetermined period. The travel trajectory in which the vehicle travels is measured. Then, information on the travel trajectory of each vehicle is aggregated, and a road on which a vehicle with a risk of drunk driving is easy to pass is extracted. A vehicle whose driving prohibition state has been canceled after vehicle driving has been prohibited due to a drunk state can be determined as a vehicle that is more likely to be drunk driving than a normal vehicle that is not prohibited from driving, A road through which many such vehicles pass can be determined as a road through which a vehicle with a risk of drunk driving can easily pass. In this regard, if the above-described road control is performed after the above-described road extraction, it is possible to effectively and efficiently prevent drunk driving. Therefore, according to the configuration of the present invention, it is possible to identify an effective road for effectively and efficiently preventing the drunk driving of the vehicle driver.

  In the above-described driving tendency totaling system, the vehicle includes the traveling locus measuring means and traveling locus transmitting means for transmitting information on the traveling locus measured by the traveling locus measuring means. A traveling locus receiving means for receiving the traveling locus information transmitted by the locus transmitting means, the information aggregating means for aggregating the traveling locus information received by the traveling locus receiving means, the road extracting means, It is good also as providing.

  Further, in the driving tendency totaling system described above, if the center includes road information transmitting means for transmitting the road information to the vehicle when the road is extracted by the road extracting means, Since it is possible to provide the driver with information on the roads on which vehicles with the risk of drunk driving are easy to pass, the vehicle drivers can be encouraged to drive vehicles with attention to vehicles with the risk of drunk driving when passing on the roads. it can.

  In addition, the above object is to determine whether or not the vehicle driver is in a drunk state, and drunk driving that prohibits / permits driving of the vehicle depending on whether or not the vehicle driver is in a drunk state. A vehicle information providing apparatus comprising: a control means, wherein when the vehicle driving prohibition state once canceled by the drunk driving control means is released, the vehicle travels within a predetermined period thereafter. The present invention is achieved by a vehicle information providing apparatus comprising: a traveling locus measuring unit that measures a locus; and a traveling locus transmitting unit that transmits information on the traveling locus measured by the traveling locus measuring unit to a center.

  In this aspect of the invention, once the driving prohibition is canceled because the driving of the vehicle is not in the drinking state after the driving is temporarily prohibited due to the drinking state of the vehicle driver, within a predetermined period thereafter. The travel trajectory on which the vehicle has traveled is measured. Then, the information on the measured vehicle travel locus is transmitted to the center. Once a vehicle is prohibited from driving due to a drunk state, the vehicle whose driving prohibited state is released can be determined as a vehicle that is more likely to be drunk than a normal vehicle, and many such vehicles pass. It can be determined that the road is an easy road for vehicles that may be drunk driving. In this regard, the center that has received the information on the travel locus transmitted from the vehicle collects the information on the travel locus of each vehicle, and is extracted mainly by the road on which a vehicle with a risk of drunk driving can easily pass. If enforcement is performed, it is possible to effectively and efficiently suppress drunk driving. Therefore, according to the configuration of the present invention, it is possible to identify an effective road for effectively and efficiently preventing the drunk driving of the vehicle driver.

  In the vehicle information providing apparatus described above, the travel locus measuring means may be configured such that the vehicle driving prohibition state once performed by the drunk driving control means is canceled within a predetermined time after the start of the driving prohibition. Thereafter, if the travel trajectory is measured within a predetermined period, it is highly possible that the driving prohibition state has been canceled due to impersonation by another person, so drunk driving is highly likely to be performed. The road where the vehicle is easy to pass can be extracted to the center, and the accuracy of the extracted road by the center can be improved.

  In this case, if the traveling locus transmitting means transmits information on the traveling locus of the vehicle measured by the traveling locus measuring means to the center together with the identification information of the vehicle, the drunk driving is extremely likely to be performed. A high vehicle (specifically, information such as an owner and a user based on identification information) can be specified by the center.

  Further, in the vehicle information providing apparatus described above, if the vehicle driver is provided with current position transmitting means for transmitting information on the current position of the vehicle to the center by a predetermined operation by the vehicle driver, the vehicle driver can drink around the own vehicle. By performing a predetermined operation when it is discovered that there is another vehicle being driven, it is possible to notify the center of the other vehicle's driving position at the position of the own vehicle, and there is a risk of drunk driving. The extraction accuracy by the center of a road on which a certain vehicle is easy to pass can be improved.

  In addition, road information receiving means for receiving road information that is likely to pass by a vehicle that may be drunk driving transmitted from the center, and providing the vehicle driver with the road information received by the road information receiving means. An in-vehicle information providing device comprising road information providing means can inform a vehicle driver of road information that is likely to be passed by a vehicle that is likely to be drunk driving transmitted from the center, and drunk driving when the road passes It is possible to encourage vehicle driving while paying attention to a vehicle that may be in danger.

  In addition, the above-mentioned purpose is measured after the vehicle prohibition state transmitted once from the vehicle when the vehicle driver is in a drinking state is canceled when the vehicle driver is not in a drinking state. A traveling locus receiving means for receiving information on the traveling locus traveled by the vehicle within a predetermined period, an information aggregating means for aggregating information on the traveling locus received by the traveling locus receiving means, and the information aggregating means. This is achieved by a drunk driving totaling device that includes road extraction means for extracting a road on which a vehicle that is likely to be drunk driving is likely to pass based on the result of the calculation.

  In the aspect of the present invention, the vehicle is measured after the vehicle prohibition state transmitted once from the vehicle when the vehicle driver is in a drunk state is canceled when the vehicle driver is not in a drunk state. When the information on the travel trajectory of the vehicle within a predetermined period is received, the travel trajectory information of each vehicle is aggregated, and a road on which a vehicle with a risk of drunk driving can easily pass is extracted. A vehicle whose driving prohibition has been canceled after the driving of the vehicle has been prohibited due to a drunk state can be judged as a vehicle that is more likely to be drunk than a normal vehicle. Therefore, it can be determined that the vehicle on which there is a risk of drunk driving is an easy road. In this respect, drastic driving suppression can be effectively and efficiently realized if the above-described road control is performed after the above road extraction. Therefore, according to the configuration of the present invention, it is possible to identify an effective road for effectively and efficiently preventing the drunk driving of the vehicle driver.

  In the drunk driving totaling apparatus described above, the travel locus receiving means receives the travel locus information transmitted from the vehicle within the predetermined period together with the vehicle identification information and is received by the travel locus receiving means. If there is a drunk vehicle identifying means for identifying a vehicle that is likely to drunk driving based on the identification information of the vehicle that has been drunk, a vehicle (specifically, identification information) that is highly likely to be drunk driving. Information such as owners and users based on) can be specified by the center.

  Further, in the above-described drunk driving totaling device, if the road extracting means extracts roads, road information transmitting means for transmitting the road information to the vehicle is provided. Since it is possible to provide information on a road on which a vehicle with a possibility of driving is easy to pass, it is possible to prompt a vehicle driving while paying attention to a vehicle with a risk of drunk driving when passing on the road.

In addition, the above-mentioned object is a travel locus storage means for storing information on a travel locus on which the vehicle has traveled,
When a predetermined event occurs in the vehicle, the travel locus reading means that reads information on the travel locus traveled by the vehicle within the predetermined period before the occurrence of the event from the travel locus storage means, and the travel locus reading means reads the information. Information summarizing means for summing up the information on the travel locus, and road extracting means for extracting a road on which a vehicle in which the predetermined event may occur in the future is likely to pass based on the summing result by the information summarizing means. It is achieved by the driving tendency totaling system characterized by having.

  In the invention of this aspect, information on the travel locus on which the vehicle has traveled is stored in the travel locus storage means. Then, when a predetermined event occurs in the vehicle, information on the travel locus that has traveled within a predetermined period before the event occurs is read from the travel locus storage means, and the information on the travel locus transmitted from each vehicle is aggregated. Thus, a road on which a vehicle in which a predetermined event may occur in the future is easy to pass in advance is extracted. When a predetermined event occurs, the road on which the vehicle traveled within the predetermined period immediately before that event is the road on which the vehicle passed immediately before the event occurred. It can be determined that the vehicle that is likely to travel is an easy road to travel in advance. In this regard, if alerting for preventing the occurrence of the event is performed on the road after the above-described road extraction, it is possible to effectively and efficiently suppress the event occurrence. Therefore, according to the present invention, it is possible to specify an effective road for effectively and efficiently suppressing the occurrence of an event.

The information of the travel locus in which the vehicle has traveled is read out from the travel locus storage means, and the road extracting means preliminarily determines whether the vehicle driver may drink in the future based on the result of the information summing means. It is good also as extracting the road which is easy to pass.

  In the present invention, “driving suppression” is a concept including not only prohibiting driving but also restricting traveling such as vehicle speed limitation and outputting an alarm.

  When vehicle driving is suppressed due to a drunk state, the road on which the vehicle has traveled within a predetermined period immediately before the suppression can be determined as a road that the driver has allowed the vehicle to pass before drinking. It can be determined that a road on which a large number of roads traveled is a road on which vehicles that are likely to be drunk in the future by the vehicle driver are easy to pass. In this regard, if the driver is alerted to prevent drinking on the road after the above road extraction, it is possible to effectively and efficiently prevent the driver from drinking alcohol. is there. Therefore, according to the present invention, it is possible to specify an effective road for effectively and efficiently suppressing the vehicle driver's drinking itself.

  Further, in the above-described driving tendency totaling system, when the vehicle collision or airbag deployment occurs as the predetermined event, the travel locus reading unit travels the vehicle within a predetermined period before the occurrence. The road extraction means is a road on which a vehicle that may cause a vehicle collision or airbag deployment in the future is likely to pass in advance based on the result of counting by the information counting means. It is good also as extracting.

  When a vehicle collision or airbag deployment occurs, the road on which the vehicle traveled within a predetermined period immediately before the occurrence is a road on which the vehicle traveled immediately before the occurrence of the vehicle collision or airbag deployment, and there are many such vehicles. It can be determined that the road on which the vehicle has traveled is a road on which vehicles that may cause an accident in the future are easy to pass in advance. In this regard, if the driver is alerted to prevent an accident on the road after the road is extracted as described above, it is possible to effectively and efficiently suppress the driving accident. Therefore, according to the present invention, it is possible to specify an effective road for effectively and efficiently suppressing a vehicle driving accident.

Achieved by a vehicle information providing apparatus comprising: a traveling locus reading means for reading information from the traveling locus storage means; and a traveling locus transmission means for transmitting information on the traveling locus read by the traveling locus reading means to a center. Is done.

  In the invention of this aspect, information on the travel locus on which the vehicle has traveled is stored in the travel locus storage means. Then, when a predetermined event occurs in the vehicle, information on the travel locus that has traveled within a predetermined period before the occurrence of the event is read from the travel locus storage means, and the information is transmitted to the center. When a predetermined event occurs, the road on which the vehicle traveled within the predetermined period immediately before that event is the road on which the vehicle passed immediately before the event occurred. It can be determined that the vehicle that is likely to travel is an easy road to travel in advance. In this regard, it is easy for a vehicle that may generate a predetermined event in the future to be extracted in advance by the center that has received the travel locus information transmitted from the vehicle to collect the travel locus information of each vehicle. If alerting for preventing the occurrence of the event is performed on the road, it is possible to effectively and efficiently suppress the occurrence of the event.

This is achieved by a driving tendency totaling device comprising road extraction means for extracting roads.

  In the invention of this aspect, when a predetermined event transmitted from the vehicle occurs and information on the travel locus traveled by the vehicle within a predetermined period before the occurrence of the event is received, the travel locus of each vehicle is received. Information is aggregated, and roads on which vehicles that may cause the event in the future are easy to pass are extracted in advance. When a predetermined event occurs, the road on which the vehicle traveled within the predetermined period immediately before that event is the road on which the vehicle passed immediately before the event occurred. It can be determined that the vehicle that is likely to travel is an easy road to travel in advance. In this regard, if an alert is made to prevent the occurrence of an event on the road after the above-described road extraction, it is possible to effectively and efficiently suppress the event occurrence. . Therefore, according to the present invention, it is possible to specify an effective road for effectively and efficiently suppressing the occurrence of an event.

  In these inventions, the “predetermined period” is a concept including a predetermined time, a predetermined distance, and a predetermined area range.

  In these inventions, the “running locus” indicates a position where the vehicle has traveled, and may be a linear shape in which the positions are collected and connected in order. It may be a dot-like shape in which the vehicle is collected, or it may indicate only one point where the vehicle has traveled at a certain point in time.

  According to the present invention, it is possible to identify an effective road for effectively and efficiently suppressing the occurrence of an event such as drunk driving or drinking itself by a vehicle driver.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration diagram of a driving tendency counting system according to an embodiment of the present invention. As shown in FIG. 1, the driving tendency totaling system of the present embodiment is composed of a vehicle and a center. The driving tendency totaling system of the present embodiment is a system that totals the tendency of drunk driving and the like by exchanging information between the vehicle and the center.

  In the present embodiment, the vehicle includes a drunk driving prevention device 10 for preventing drunk driving by the driver. The drunk driving prevention device 10 includes an alcohol detection ECU 12 mainly composed of a computer. The alcohol detection ECU 12 is an electronic control unit for determining whether or not the vehicle driver is in a drinking state. An alcohol sensor 14 is electrically connected to the alcohol detection ECU 12. The alcohol sensor 14 is a sensor that is disposed near the driver's seat and outputs a signal corresponding to the alcohol concentration in the air. The alcohol detection ECU 12 detects the alcohol concentration in the air near the driver's seat based on the output signal of the alcohol sensor 14. And it is discriminate | determined whether the driver | operator of a driver's seat is in a drinking state based on whether the detected alcohol density | concentration is more than the predetermined defined value.

  The alcohol detection ECU 12 is electrically connected to an operation permission ECU 16 mainly composed of a computer. The alcohol detection ECU 12 described above supplies a signal indicating a determination result as to whether or not the driver is in a drinking state to the driving permission ECU 16. The driving permission ECU 16 determines whether to permit or prohibit driving of the vehicle based on a signal supplied from the alcohol detection ECU 12.

  An engine ECU 18 mainly composed of a computer is electrically connected to the operation permission ECU 16. The driving permission ECU 16 supplies a signal indicating permission / prohibition of vehicle driving to the engine ECU 18. The engine ECU 18 determines whether the vehicle operation is permitted or prohibited based on a signal from the operation permission ECU 16.

  The engine ECU 18 is electrically connected to an engine actuator 20 such as an ignition device or a fuel supply device. The engine ECU 18 detects various vehicle states in a situation where vehicle operation is to be permitted, and issues a drive command to the engine actuator 20 so that the vehicle engine is appropriately driven according to the vehicle state.

  The driving permission ECU 16 is also electrically connected to a navigation ECU 22 mainly composed of a computer. The navigation ECU 22 has a map database that stores road map information, position information of main facilities, and the like, and can display a map stored in the map database on an in-vehicle display.

  The navigation ECU 22 is connected to a GPS antenna 24 that receives a GPS signal transmitted from a GPS satellite. The navigation ECU 22 detects the current position of the host vehicle by referring to the road map information based on the GPS signal received by the GPS antenna 24, and a mark indicating the detected current position is displayed on the in-vehicle display. It can be displayed superimposed on the map.

  The navigation ECU 22 also has a nonvolatile memory 26. The navigation ECU 22 can temporarily store in the memory 26 information on the vehicle position detected as described above. The information on the vehicle position stored in the memory 26 is stored for a predetermined period such as a predetermined time or a predetermined travel distance after the start of the storage. Information on the vehicle position stored in the memory 26 is read in accordance with a command from the driving permission ECU 16 via the navigation ECU 22 and is output as a travel locus of the vehicle within a predetermined period.

  The driving permission ECU 16 also has a nonvolatile memory 28. The memory 28 stores at least information (unique ID information) indicating the vehicle number, owner, and user of the host vehicle.

  The alcohol detection ECU 12, the operation permission ECU 16, and the navigation ECU 22 are connected to each other via the LAN 30. Further, these ECUs 12, 16 and 22 are connected to the communication module 32 via the LAN 30. The communication module 32 is a mobile phone or a car phone for performing wireless communication with a server side provided in the center through a predetermined wireless communication network. The communication module 32 receives a supply of a transmission command from the operation permission ECU 16 through the LAN 30 and wirelessly transmits predetermined information as described below from the transmission / reception antenna 34 according to the transmission command, and is transmitted wirelessly from the outside as described below. Predetermined information is received by the transmission / reception antenna 34 and the received information is supplied to the driving permission ECU 16 through the LAN 30.

  A current position transmission request switch 36 is also connected to the driving permission ECU 16. The current position transmission request switch 36 is arranged on an instrument panel or the like of the driver's seat so that it can be operated by the vehicle driver. Information on the current position of the host vehicle detected by the navigation ECU 22 by the ON operation is sent via the communication module 32. This is a switch for requesting transmission to the outside. Based on the state of the current position transmission request switch 36, the driving permission ECU 16 determines whether or not transmission of the current position information of the host vehicle is requested to the outside.

  Further, in this embodiment, the center includes a server 40 for counting the tendency of drunk driving of the vehicle. The server 40 may be installed in a country, a local public organization, a police station, or the like. The server 40 is mainly composed of a computer and includes a communication module 42, a CPU 44, and a storage device 46.

  The communication module 42 is a communication device that performs wireless communication with the vehicle communication module 32 through a predetermined wireless communication network. The CPU 44 is electrically connected to the communication module 42 and can exchange information that the communication module 42 transmits / receives to / from the outside. The communication module 42 wirelessly transmits predetermined information, which will be described later, to the outside from the transmission / reception antenna 48 in accordance with a transmission command from the CPU 44, and also receives predetermined information, which will be described later, wirelessly transmitted from the outside by the transmission / reception antenna 48. Is supplied to the storage device 46. The CPU 44 uses the communication module 42 to totalize various trends related to the drunk driving of the vehicle, and provides the totaled result to the vehicle side. The storage device 46 stores information processed by the CPU 44, registered vehicle information, and the like.

  Next, operation | movement of the drunk driving prevention apparatus 10 which a vehicle mounts in a present Example first is demonstrated.

  In this embodiment, the alcohol detection ECU 12 periodically detects the alcohol concentration in the air in the vicinity of the driver's seat in the vehicle based on the output signal of the alcohol sensor 14 after the vehicle is started (ignition on), and the detected alcohol concentration is Then, it is determined whether or not the vehicle driver is in a drinking state including at least a drunk state, which is equal to or more than a predetermined value that is defined in advance. And the information which shows the discrimination | determination result (namely, whether a vehicle driver is in a drinking state) is transmitted to driving permission ECU16 through LAN30.

  When the information from the alcohol detection ECU 12 transmitted through the LAN 30 is received, the driving permission ECU 16 determines whether or not it is detected from the received information that the vehicle driver is in a drinking state. If it is detected as a result of the determination that the vehicle driver is not in a drinking state, a decision is made to permit driving of the vehicle, and a command signal indicating permission for driving is supplied to the engine ECU 18.

  When the engine ECU 18 receives a signal indicating the driving permission from the driving permission ECU 16, the engine ECU 18 determines that the driving of the vehicle is permitted and permits the driving of the vehicle engine, and responds to the detected vehicle state. Thus, a drive command is issued to the engine actuator 20 so that the vehicle engine is appropriately driven. In this case, the engine actuator 20 drives the vehicle engine in accordance with a drive command from the engine ECU 18, so that the vehicle engine is driven normally.

  On the other hand, when it is detected that the vehicle driver is in a drunk state based on information received from the alcohol detection ECU 12, the driving permission ECU 16 determines to prohibit driving of the vehicle, and sends a signal indicating driving prohibition to the engine. The ECU 18 is supplied.

  When the engine ECU 18 receives a signal indicating the prohibition of driving from the driving permission ECU 16, the engine ECU 18 determines that the driving of the vehicle is to be prohibited, prohibits the driving of the vehicle engine, and sends a drive command to the engine actuator 20. Cancel or stop. In this case, the engine actuator 20 does not drive the vehicle engine, and the vehicle engine is stopped or stopped.

  Thus, according to the drunk driving prevention apparatus 10 of the present embodiment, whether or not the vehicle driver is in a drunk state based on whether or not the alcohol concentration in the air in the vicinity of the driver's seat in the vehicle is equal to or higher than a specified value. If the vehicle driver is not in a drinking state as a result of the determination, the vehicle engine can be driven and the vehicle engine can be driven as usual, while the vehicle driver is in a drinking state. The driving of the vehicle engine can be stopped and stopped by prohibiting the driving of the vehicle. For this reason, according to the present embodiment, when the vehicle driver is in a drunk state, the driving of the vehicle engine is prohibited and the drunk driving of the vehicle becomes impossible, so that the drunk driving can be prevented. It is possible to ensure safe driving of the vehicle.

  By the way, in the device that determines whether or not the vehicle driver is in a drinking state based on the alcohol concentration in the air in the vicinity of the driver's seat in the vehicle as in this embodiment, and permits or prohibits vehicle driving according to the determination result. After it is determined that the person who is driving is in a drunk state and driving of the vehicle is prohibited, the person who actually drives tries to lift the driving prohibition, and the driver impersonates the person who is not the person and drinks It may be misjudged if it is not in a state. In this case, the driving prohibition of the vehicle is canceled and the driving is permitted because the driver is not in a drunk state, and it becomes possible for the drunk person to drive the vehicle illegally. If so, it is difficult to effectively and appropriately prevent drunk driving of the vehicle.

  In general, to prevent drunk driving of vehicles, the police may control drunk driving, but if the control point is set at random, the drunk driving control will be effective. Can not be. Therefore, the driving tendency totaling system of the present embodiment has a first feature in that drunk driving by a vehicle driver is effectively prevented by obtaining an effective control road point for drunk driving.

  In addition, since the control of drunk driving is usually performed afterwards based on whether or not the driver is actually drunk, it is possible to indirectly prevent drunk driving of the vehicle. However, it is insufficient to prevent drunk driving. That is, drunk driving can be prevented more effectively if the drunk itself can be effectively suppressed before the driver drunk. Therefore, the driving tendency counting system of the present embodiment is to effectively prevent drunk driving by the vehicle driver by obtaining a road point where a vehicle that the vehicle driver may drink in the future is easy to pass in advance. It has the 2nd characteristic.

  Hereafter, the characteristic part of a present Example is demonstrated with reference to FIG. 2 thru | or FIG. FIG. 2 shows a flowchart of an example of a control routine that is executed in order to obtain a road point where a vehicle that may be drunk in the future by a vehicle driver is likely to pass in the driving tendency totaling system of the present embodiment. FIG. 3 is a diagram for explaining a method for obtaining a road point where a measure for effectively suppressing drinking in this embodiment is to be executed. FIG. 4 shows a flowchart of an example of a control routine executed in order to obtain an effective control road point for drunk driving in the driving tendency totaling system of this embodiment. Moreover, FIG. 5 shows the figure for demonstrating the method of calculating | requiring the road point which should perform the effective control of drunk driving in a present Example.

  In the present embodiment, the navigation ECU 22 of each vehicle periodically detects the current position of the host vehicle based on the GPS signal from the GPS satellite after the vehicle is started, and stores information on the detected current position in the memory 26. Remember me. The information on the own vehicle position once stored in the memory 26 is from the start of the storage until a predetermined time (for example, 5 minutes or 10 minutes) elapses or the traveling distance of the vehicle is a predetermined traveling distance (for example, 1 km). It continues to be stored until it disappears, and then erased. In this regard, when the own vehicle positions stored in the memory 26 are connected in the order of detection, a traveling locus that is passed while the own vehicle has traveled for a predetermined time or a predetermined traveling distance is formed.

  When it is detected that the vehicle driver is in a drunk state based on information from the alcohol detection ECU 12 transmitted through the LAN 30, the driving permission ECU 16 should prohibit driving of the engine (when an affirmative determination is made in step 100). As described above, the driving prohibition signal is supplied to the engine ECU 18 (step 102), and further, the navigation ECU 22 is memorized for a predetermined time or a predetermined traveling distance until the drinking is detected (that is, before driving is prohibited). 26, a signal for requesting to supply the driving permission ECU 16 with information on the vehicle position stored in the vehicle 26, that is, information on a travel locus of the vehicle within the predetermined period (hereinafter referred to as a pre-drinking travel locus).

  When the navigation ECU 22 receives a signal requesting the supply of information on the travel path before drinking from the driving permission ECU 16, the navigation ECU 22 reads information on the travel path before drinking of the vehicle that has traveled within the predetermined period from the memory 26, and Information on the driving trajectory before drinking is supplied to the driving permission ECU 16 (step 104).

  When the driving permission ECU 16 receives the pre-drinking travel trajectory information from the navigation ECU 22 after requesting the pre-drinking travel trajectory information to the navigation ECU 22, the driving permission ECU 16 adds the ID information stored in the memory 28 to the pre-drinking travel trajectory information. Then, a transmission command is sent to the communication module 32 via the LAN 30 so that the information is transmitted to the center side (step 106). In this case, information on the driving trajectory before drinking that the vehicle has traveled before the occurrence of drinking detection (that is, driving prohibition) is transmitted from the vehicle to the center.

  When the communication module 42 receives the pre-drinking travel trajectory information from the vehicle, the CPU 44 of the center server 40 stores the received pre-drinking travel trajectory information in the storage device 46 (step 150). When the CPU 44 receives the driving trajectory information before drinking from a plurality of vehicles that are prohibited from driving due to the detection of drinking, the CPU 44 counts the information on the driving trajectory before drinking (step 152) and drives the driver of the vehicle who drinks the alcohol. A vehicle on which a vehicle driver may drink in the future is likely to pass in advance on a road on which a lot of vehicles run before drinking (that is, a road where a vehicle driver frequently passes the vehicle before drinking) Extract as a road (step 154). Specifically, for each road, for example, the percentage obtained by dividing the total number of traffic by the traffic volume of ordinary vehicles and the road type (road thickness) is the vehicle that the vehicle driver may drink in the future. Is included in the range of the rate specified as easy-to-pass roads in advance, and if a positive determination is made, vehicles that may be drunk in the future by the vehicle driver pass in advance. This is extracted as an easy-to-use road.

  For example, the above extraction is performed with one road link from the intersection to the intersection as a unit, and as shown in FIG. Vehicles that are likely to travel are extracted as easy-to-pass roads. In this extraction, roads on which vehicles that are likely to be drunk in the future by vehicles are easy to pass are classified into a plurality of hierarchies (for example, roads that are extremely easy to pass according to the number of traffic and roads that are easy to pass normally). Or two or more hierarchies that are further subdivided according to the number of traffic.

  As described above, the CPU 44 is based on the pre-drinking travel trajectory information from a plurality of vehicles that are prohibited from driving due to detection of drinking, and the road on which the vehicle driver may drink in the future is easy to pass in advance. When the road is identified, for example, the road is displayed on the display on which the road map is displayed. The road is displayed so as to be distinguished from the road), or the position of the specific road is displayed in characters on the display (step 156).

  According to such a process, it is possible to specify a road on which the vehicle driver who is likely to drink in the future on the center side is likely to pass through in advance, and to provide position information of the specific road to others. It becomes possible. For this reason, for the road specified by such processing, install or urge the driver of the vehicle actually passing through the specific road not to drink alcohol itself, etc. By providing such road information, it is possible to effectively and efficiently realize the suppression of the driver's drinking itself.

  Therefore, according to the system of the present embodiment, each vehicle that has been prohibited from driving due to drinking detection traveled within a predetermined period before the prohibition of driving, and the vehicle driver will continue to drink. By extracting the roads on which vehicles that are likely to pass are easy to pass in advance, it is possible to identify roads that are effective in effectively and efficiently deterring the driver's drinking. For this reason, drunk driving by the vehicle driver can be effectively and efficiently inhibited, and drunk driving by the vehicle driver can be effectively prevented.

  Further, in this embodiment, after the driving permission ECU 16 is prohibited from driving due to the driver's drinking detection, the driver may not be in a drinking state based on the information received from the alcohol detection ECU 12. It is determined whether or not the driving prohibition is canceled and the driving is permitted, that is, whether or not the vehicle switches from drinking detection to non-drinking detection and switches from driving prohibition to driving permission (step 200).

  Then, when it is detected that drinking prohibition is switched from drinking detection to non-detection of driving, the driving permission signal is supplied to the engine ECU 18 as described above to permit driving of the engine (step 202). Further, the navigation ECU 22 is notified that the prohibition of driving of the vehicle has been lifted, and thereafter, information on the vehicle position detected based on the GPS signal from the GPS satellite during a predetermined time or a predetermined mileage. A signal requesting to be supplied to the driving permission ECU 16 is supplied as information on a vehicle travel locus (hereinafter referred to as a travel locus after drinking) during the predetermined period.

  When the navigation ECU 22 receives a notification from the driving permission ECU 16 that the prohibition of driving of the vehicle has been canceled, the navigation ECU 22 first stores information on the vehicle position detected within a predetermined period in the memory 26 (step 204). When the predetermined period has elapsed (when an affirmative determination is made in step 206), the vehicle position information within the predetermined period is read from the memory 26 as post-drinking travel trajectory information, and the post-drinking travel trajectory information. Is supplied to the driving permission ECU 16 (step 208).

  When the driving permission ECU 16 receives the information about the driving trajectory after drinking from the navigation ECU 22 after notifying the navigation ECU 22 that the driving prohibition is canceled, the driving permission ECU 16 adds the ID information stored in the memory 28 to the information on the driving trajectory after drinking. Then, a transmission command is issued to the communication module 32 via the LAN 30 so that the information is transmitted to the center side (step 210). In this case, after the drunk detection (that is, driving prohibition) once generated is released from the vehicle to the center, information on the after-drinking travel locus traveled by the vehicle is transmitted.

  When the post-drinking run track information from the vehicle is received by the communication module 42, the CPU 44 of the center server 40 stores the received post-drinking run track information in the storage device 46 (step 250). When the CPU 44 receives the driving trajectory information after drinking from a plurality of vehicles whose driving prohibition has been lifted, the CPU 44 counts the information on the driving trajectory after drinking (step 252), and driving is temporarily prohibited due to drinking detection. Compared with other roads, there is a risk of drunk driving compared to other roads on which many vehicles travel after the prohibition of driving is canceled (that is, roads on which the vehicle driver frequently passes after canceling driving prohibition). A road that is easy to pass through is extracted (step 254). Specifically, for each road, for example, the ratio obtained by dividing the total number of traffic by the traffic volume of ordinary vehicles and the type of road (thickness of the road) is easy for vehicles with the risk of drunk driving. It is determined whether or not the vehicle is included in the range of the ratio defined as a road, and if the determination is affirmative, the road is extracted as a road through which a vehicle that may be drunk is likely to pass.

  For example, the above extraction is performed with one road link from the intersection to the intersection as a unit. As shown in FIG. 5, a road link with a large number of vehicles passing there is a risk of drunk driving. It is extracted as a road through which vehicles are easy to pass. In this extraction, roads that are likely to be driven by drunk driving vehicles are classified into two or more levels (for example, two levels of roads that are very easy to pass and roads that are easy to pass or not) It may be divided into three or more hierarchies that are further subdivided according to the number of units.

  As described above, the CPU 44, based on the post-drinking travel trajectory information from a plurality of vehicles that have been released from the prohibition of driving once caused by the detection of drunk, on a road on which a vehicle that may be drunk is likely to pass. Once extracted, the road is identified and, for example, the road on which the road map is displayed can be distinguished from other roads (roads where drunk driving vehicles do not pass). Display is performed, or the position of the specific road is displayed in characters on the display (step 256).

  According to such processing, the center side (such as an administrator) may specify a road on which a vehicle drunk by the driver (that is, a vehicle on which the driver drunk is driven) is easier to pass than other roads. It is possible to provide position information of the specific road to others. For this reason, if a checkpoint for the control of drinking by a police station or the like is installed on the road identified by such processing, or if the establishment of the checkpoint is encouraged, the drunk driving of the vehicle can be effectively and efficiently performed. It becomes possible to control and drunk driving can be effectively and appropriately prevented.

  The road information specified by the center as described above may be widely provided to third party vehicles using the communication module 42 as VICS information. In this configuration, each vehicle (including other vehicles) side displays information on roads on which the drunk driving vehicle easily passes when the communication module 32 receives information from the center side. To the vehicle driver. The provision to the vehicle driver, for example, provides a road display in which the specific road is distinguished from other roads (roads on which drunk driving vehicles do not pass) on a display on which a road map is displayed. Or a device that outputs a sound when passing through the specific road. For this reason, according to this measure, it is possible to encourage the vehicle driver to travel safely while paying attention to the drunk driving vehicle that is likely to exist in the vicinity when the specific road is passed.

  Therefore, according to the system of the present embodiment, vehicles that have been prohibited from driving due to detection of drunking are aggregated the travel trajectories that have been traveled after the cancellation of the driving prohibition thereafter, and there is a risk of drunk driving By extracting roads that are easy to pass, it is possible to identify roads that are effective in effectively and efficiently preventing drunk driving by vehicle drivers. For this reason, drunk driving by a vehicle driver can be effectively prevented.

  In the above-described embodiment, the drunk driving prevention device 10 of the vehicle corresponds to the “information providing device” recited in the claims, and the driving permission ECU 16 receives the information received from the alcohol detection ECU 12. Based on whether or not the vehicle driver is in a drunk state, it is determined whether or not the vehicle driver is in a drunk state. By determining whether to permit or prohibit the driving of the vehicle and supplying a command signal corresponding to the determination to the engine ECU 18, the “drinking driving control means” described in the scope of the claims is the navigation ECU 22. Claimed by detecting the vehicle position based on the GPS signal from the GPS satellite continuously for a predetermined time or predetermined distance after the prohibition is released The “traveling track measuring means” described in claims 1 to 7 of the range is configured so that the communication module 32 transmits information on the traveling track after drinking that the vehicle has traveled after canceling the driving prohibition to the center. The “traveling path transmitting means” described in claims 1 to 7 receives information on a road provided by the center through which drunk driving vehicles are easy to pass. The “means” means “road information providing means” described in the claims by providing the vehicle driver with information on a road on which the vehicle to be drunk is easy to pass, as received by the communication module 32. Are realized.

  In addition, the center corresponds to the “driving tendency totaling device” described in the claims, and the communication module 42 of the center server 40 receives the information on the trajectory after drinking sent from each vehicle. The “travel locus receiving means” described in claims 1 to 3 and 9 to 11 of the claims, the CPU 44 counts the information of the after-drinking travel locus from each vehicle. Claims 1 to 3 and Claims 1 to 3 and Claims 1 to 3 and 9 to 11 described above extract the road on which the drunk driving vehicle is easy to pass based on the result of the counting. The “road extraction means” described in 9 to 11 allows the communication module 42 to transmit the extracted information on the road on which the drunk driving vehicle is easy to pass to the third party vehicle side as VICS information. Patent set forth in the claims, "road information transmission means" are realized respectively by.

  The vehicle-side navigation ECU 22 periodically stores information on the current position of the host vehicle detected based on GPS signals from GPS satellites in the memory 26 according to the claims. "Means" read out the information on the running trajectory of the vehicle before drinking from the memory 26 in response to a command from the driving permission ECU 16, and the "running trajectory reading means" described in claims 12 to 14 and 16 of the claims. The communication module 32 transmits the information on the running track before drinking read from the memory 26 to the center, whereby the “running track transmitting means” described in claims 12 to 14 and 16 of the claims is further provided. The communication module 42 on the center side receives the information of the pre-drinking travel locus transmitted from each vehicle, and claims 12 to 14 of the claims. The “running trajectory receiving means” described in No. 17 and No. 17 totalize the information on the running trajectory before drinking from each vehicle, whereby the “information tallying means” described in claims 12 to 14 and 17 of the claims is: The “road extraction means” described in claims 12 to 14 and 17 of the claims is obtained by extracting a road on which a vehicle driver is likely to drink in the future based on the tabulated result and is easy for a vehicle to pass. , Each has been realized.

  By the way, in the above-mentioned embodiment, after driving prohibition is temporarily performed due to drinking detection, when it is detected that the vehicle driver is not in the drinking state and the driving prohibition state is released, The travel trajectory after drinking within a predetermined period is measured, and the information on the travel trajectory after drinking is transmitted from the vehicle to the center. The measurement and transmission of the travel trajectory after drinking are performed for a predetermined time (for example, 10 It may be performed only when the operation prohibition state is canceled within minutes or 3 hours.

  If the driving prohibition is canceled within a short time after the start of the driving prohibition, there is a high possibility that the driving prohibition has been canceled by impersonation by another person, or the driving prohibition is There is a high possibility that the release condition is satisfied and released only by taking a nap. Therefore, according to the above-described modification, it is possible to collect and extract information on roads on which a vehicle with a high possibility of drunk driving is easy to pass to the center side, which is effective for drunk driving by a vehicle driver. Prevention can be realized.

  In this modification, since the vehicle ID information is transmitted at the same time when the information about the driving trajectory after drinking is transmitted from the vehicle to the center, the center side selects a vehicle that is highly likely to be drunk. It becomes possible to specify. In this case, the “drinking vehicle specifying means” described in the claims is realized by the center CPU 44 specifying a vehicle that is highly likely to be drunk.

  Further, in the above embodiment, the vehicle is caused to transmit the information about the driving trajectory after drinking within a predetermined period to the center after canceling the driving prohibition due to the detection of drinking, and the center is allowed to transmit the driving trajectory after drinking from each vehicle. Based on this information, roads on which drunk driving vehicles are easy to pass are extracted, and further, information on the vehicle position detected when the current position transmission request switch 36 is turned on is sent to the center. At the same time, the center is caused to extract a road on which a drunk driving vehicle is easy to pass based on both the information on the trajectory after drinking from each vehicle and the vehicle position information when the current position transmission request switch 36 is turned on. It is good as well.

  In this modification, when the driver of the vehicle finds another vehicle that is drunk in the vicinity of the own vehicle, the vehicle driver turns on the current position transmission request switch 36 to set the position of the drunk vehicle at that time. The navigation ECU 22 transmits the information to the center instead of the information on the vehicle position detected by the navigation ECU 22. That is, when the current position transmission request switch 36 is turned on, the vehicle driving permission ECU 16 detects that the vehicle position information is requested to be transmitted to the center by the navigation ECU 22 at that time. It requests that the information on the vehicle position is transmitted to the center side via the communication module 32. When the navigation ECU 22 receives such a request from the driving permission ECU 16, the navigation ECU 22 issues a transmission command to the communication module 32 via the LAN 30 so that the information on the vehicle position detected at that time is transmitted to the center side. In this case, the position information of the vehicle is transmitted from the vehicle to the center.

  When the center module 44 receives the vehicle position information from the vehicle by turning on the current position transmission request switch 36 in the communication module 42, the center CPU 44 stores the received vehicle position information in the storage device 46. Based on the after-drinking travel trajectory information from the vehicle for which driving prohibition due to the detection of drinking that has occurred once and the vehicle position information by turning on the current position transmission request switch 36 from a normal vehicle, A road link including a large number or a large number of vehicle positions is extracted as a road through which a vehicle that may be drunk is likely to pass.

  According to such a modification, the center can inform the center of the location where the drunk driving was performed on behalf of the drunk vehicle, so that the accuracy of extraction by the center of the road on which the vehicle likely to be drunk driving can pass Can be improved. In such a modified example, the vehicle communication module 32 transmits the vehicle current position information detected by the navigation ECU 22 when the current position transmission request switch 36 is turned on to the center, whereby the “current position” is described in the claims. "Transmission means" is realized.

  Further, in the above embodiment, when the driving prohibition once caused by drinking detection is canceled by drinking non-detection, the post-drinking driving trajectory in which the vehicle has traveled within a predetermined period thereafter is measured. The information on the driving trajectory after drinking is transmitted from the vehicle to the center, and the vehicle is simultaneously measured when measuring the driving trajectory after drinking (specifically, when the vehicle position is detected within a predetermined period after canceling driving prohibition). The speed information at each point may be added and transmitted at the time of transmitting information on the travel locus after drinking from the vehicle to the center.

  According to such a modified example, the center side can extract a road on which a vehicle with a risk of drunk driving can easily pass, and the speed at each point on the extracted road can be grasped. From the speed, it is possible to select a point where it is easy to control drinking, that is, an optimal checkpoint installation point. For this reason, it becomes possible to prevent drunk driving of a vehicle more effectively and appropriately.

  In the above embodiment, the vehicle engine is driven or stopped as the vehicle driving permission or driving prohibition, but the shift lever is permitted or prohibited from moving from the parking position or neutral position. A thing, a steering lock, or the lock release may be performed.

  In the above embodiment, the vehicle itself detects its current position and stores it in the memory 26 in order to measure the pre-drinking travel trajectory or the post-drinking travel trajectory, and the specific information stored in the memory 26 is appropriately stored. However, the present invention is not limited to this, and the vehicle and the center communicate with each other as needed to transmit the current position information of the vehicle from the vehicle to the center. The center may store the position information of the vehicle in its own memory. At this time, the position information may be stored for each vehicle in the center memory, or the position information may be stored without distinguishing the vehicle. In such a modification, when the center receives a notice from the vehicle that the driving of the vehicle or the prohibition of alarm output has been performed because the vehicle driver is in a drunk state, the vehicle is traveling immediately before. Read the information of the specified position from its own memory. Then, information on a large number of positions read out in this way (that is, information on the driving trajectory before drinking) is totaled to extract roads on which vehicles that are likely to be drunk in the future by the vehicle driver are easy to pass. Also in this modified example, it becomes possible to specify a road on the center side where a vehicle driver who is likely to drink in the future is likely to pass in advance, and the same effect as in the above embodiment can be obtained. .

  In the above embodiment, a single vehicle measures both the pre-drinking travel trajectory and the post-drinking travel trajectory and transmits them to the center. However, the present invention is not limited to this. Alternatively, at least one travel locus may be measured and transmitted to the center.

  In the above embodiment, driving of the vehicle is prohibited due to detection of drinking, but if the system only measures the driving trajectory before drinking without measuring the driving trajectory after drinking, it is caused by the detection of drinking. And what is necessary is just to suppress the driving | operation of a vehicle. In addition, this driving | running suppression is not only prohibiting a driving | operation but it is a concept including restrict | limiting driving | running | working, such as a vehicle speed restriction | limiting, and outputting a warning besides that.

  Further, in the above-described embodiment, it is effective in effectively preventing drunk driving by the vehicle driver by obtaining a road point where the vehicle driver who is likely to drink in the future is likely to pass in advance. Although the road is specified, the present invention is not limited to this. When a predetermined event such as a vehicle collision or airbag deployment occurs, the vehicle travels within a predetermined period before the event occurs. The information on the travel trajectory is read out from the travel trajectory storage means, and then the information on the travel trajectory of each vehicle is aggregated. Based on the aggregated result, a vehicle that may cause the event in the future is likely to pass in advance. It is good also as specifying a road effective in preventing generation | occurrence | production of a predetermined | prescribed event by calculating | requiring a road point.

  FIG. 6 shows a configuration diagram of the driving tendency totaling system of the modified example. In FIG. 6, the same parts as those shown in FIG. FIG. 7 shows a flowchart of an example of a control routine that is executed in the driving tendency totaling system according to the present modified example to obtain a road point where a vehicle that may cause an accident in the future is easy to pass in advance.

  In this modified example, the airbag ECU 102 of the information providing apparatus 100 mounted on the vehicle determines whether or not the own vehicle has collided using the collision sensor 104 and protects the passengers and the like when it is determined that a collision has occurred. The process which expands an airbag as much as possible is performed.

  When the airbag ECU 102 determines that a collision has occurred or has deployed the airbag (when the determination in step 200 is affirmative), the airbag ECU 102 determines a predetermined time or predetermined travel time until the collision detection or airbag deployment. Requests that the information on the vehicle position stored in the memory 26 during the distance, that is, the information on the traveling locus of the traveling vehicle (hereinafter referred to as a traveling locus before the accident) within the predetermined period, be supplied to the own airbag ECU 102. To supply the signal. In this case, the navigation ECU 22 reads information on the travel locus before the accident from the memory 26 (step 204) and supplies the information to the airbag ECU 102. When the airbag ECU 102 receives the pre-accident traveling locus information from the navigation ECU 22, the airbag ECU 102 adds the ID information stored in the memory 28 to the pre-accident traveling locus information, and transmits the information to the center side. Thus, a transmission command is sent to the communication module 32 via the LAN 30 (step 206).

  When the communication module 42 receives the pre-accident traveling locus information from the vehicle, the CPU 44 of the center server 40 first stores the received pre-accident traveling locus information in the storage device 46 (step 250). When the pre-accident travel locus information is received from a large number of vehicles in which vehicle collision or airbag deployment has occurred, the information on the pre-accident travel locus is totaled (step 252), and many accident vehicles travel before the accident. The road that is likely to have an accident in the future is extracted in advance as a road that is easy to pass (step 254). When the CPU 44 extracts a road on which a vehicle that may cause an accident in the future is easy to pass in this way, the CPU 44 identifies the road, and for example, the specific road is displayed on the display on which the road map is displayed. A road is displayed so as to be distinguished from (a road in which vehicles that may cause an accident in the future are unlikely to pass in advance), or the position of the specific road is displayed on the display in characters (step 256).

  According to such a modified example, for example, each vehicle in which a vehicle collision or airbag deployment has occurred travels within a predetermined period before the occurrence of the vehicle, and information on the travel trajectory has been collected in advance. By extracting roads that are easy to pass, it is possible to identify roads that are effective in effectively and efficiently suppressing vehicle driving accidents. In this regard, since it is possible to grasp the road on which the accident vehicle is easy to travel in advance, the vehicle driver can be made aware of the road that is likely to encounter dangerous driving vehicles, and drive the road more carefully. As a result, a vehicle driving accident can be effectively and efficiently suppressed.
