Description

  The present invention relates to a technique for reliably transmitting predetermined information to a user even when the user is away from a vehicle.

  For example, the current position is detected by GPS or the like as the vehicle travels, and the current position is displayed on the display together with the road map, so that the destination can be smoothly reached or an appropriate route from the current position to the destination can be obtained. An in-vehicle navigation device that performs setting and guidance is known, and contributes to smoother driving.

Some of these in-vehicle navigation devices have a communication function for communicating with an external communication device such as a home server installed at home, and when emergency information transmitted from the external communication device is received. Some of them notify the user in the vehicle by display or voice. The above-mentioned “emergency information” refers to information notifying an emergency situation. For example, an intruder is detected or a gas leak is detected by a security device such as a security sensor installed at home or a gas leak alarm. For example, information indicating that the information has been detected, information indicating that a visitor has operated an interphone installed at the entrance of the home, and the like can be cited (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2002-64881 (8th page, FIGS. 6 and 7)

  By the way, in the vehicle-mounted navigation device as described above, for example, when the user is away from the vehicle on which the vehicle-mounted navigation device is mounted, when the parked vehicle is stolen, You may not be aware of theft of the vehicle until you have completed your job and returned to where you parked the vehicle. Then, there was a problem that measures such as contacting the police were delayed.

  In addition, this is not limited to in-vehicle navigation devices. For example, it is mounted on a vehicle such as an amateur radio device and has a communication function and a notification function, for example, a vehicle such as a mobile phone, a PDA, and a laptop computer. It is considered that the same problem arises in a case that a user carries when boarding and has a communication function and a notification function.

  The present invention has been made in view of such problems, and its purpose is to provide predetermined information such as theft information indicating that the vehicle has been stolen even when the user is away from the vehicle. It is to provide a technology that reliably conveys to the user.

  The vehicle state information transmission device according to claim 1, wherein the transmission destination information storage means stores transmission destination information and at least one user information, and is configured to solve the above-described problem. And stores the destination information in association with each other. And a control means judges whether predetermined information needs to be transmitted according to the state of a vehicle judged by vehicle state judgment means. If it is determined that the predetermined information needs to be transmitted, the control means sends the destination information associated with the user information indicating the user specified by the user specifying means from the destination information storage means. Reading and transmitting the predetermined information to the transmission destination based on the transmission destination information.

  The transmission destination information refers to information regarding the transmission destination. The transmission destination is an object to which predetermined information is transmitted. Specific examples of the transmission destination include a mobile phone, a PDA, a computer used by a user in an office, and the like. Specific examples of the destination information include a telephone number for specifying a mobile phone as a destination, a mail address that can be used by the user, and the like. The user information is information indicating the user.

  Therefore, according to the vehicle state information transmission device according to the first aspect of the present invention, even when the user is away from the vehicle, predetermined information can be reliably transmitted to the user according to the state of the vehicle. Even when there are a plurality of users, if a transmission destination of predetermined information is selected for each user, the predetermined information can be reliably transmitted to the user.

  By the way, when a vehicle parked as described above is stolen, the user may not be aware of the theft until the user finishes the job and returns to the place where the vehicle is parked. Then, there was a problem that measures such as contacting the police were delayed. Therefore, when the vehicle is stolen, it is conceivable to transmit the fact to the outside. Specifically, as in claim 2, the vehicle state determination means determines whether the vehicle has been stolen as the vehicle state. For example, (a) the door of the locked vehicle was pry open, (b) the vehicle started (engine started) even though the key was not inserted into the key cylinder, and (c) stopped It is determined that the vehicle is stolen because the vehicle inside is inclined more than the slope of the road. Here, when it is determined by the vehicle state determination means that the vehicle has been stolen, the above-described control means uses the “theft information” indicating that the vehicle has been stolen as predetermined information to the transmission destination. To send to. The theft information may include the “cause” that the vehicle was stolen as in the above (a) to (c) and the “time” when the vehicle was stolen. In this way, even if the vehicle is stolen, the user can quickly know that fact.

  When transmitting theft information in this way, the vehicle status acquisition means acquires the status of the vehicle, and transmits the current status of the vehicle and the status of the vehicle such as video / audio inside the vehicle to the destination along with the theft information. You may do it. Here, as a specific example of the situation of the vehicle, the current position of the vehicle specified by the position specifying means such as GPS, the image in the vehicle photographed by the video camera installed in the vehicle, the microphone installed in the vehicle, etc. In-vehicle sound obtained by the above, route information calculated by the navigation device, and the like. In this way, even if the vehicle is stolen, in addition to being able to quickly know to that effect, it is also possible to know the vehicle status in real time, such as the current position of the vehicle and the video / audio inside the vehicle. Can do.

  By the way, it is conceivable to transmit the running state of the vehicle to a home server or the like installed at the user's home. Specifically, as in claim 3, the vehicle state determination means determines whether or not the vehicle is in a dangerous traveling state as the vehicle state. When the vehicle state determination unit determines that the vehicle is in a dangerous driving state, the control unit transmits “warning information” indicating that the vehicle is in a dangerous driving state to the transmission destination as predetermined information. Send to sending means. In this way, the running state of the vehicle can be notified to the outside of the family in real time.

  In this way, when the vehicle running state is transmitted, the vehicle state obtaining unit obtains the vehicle state, and the vehicle state such as the current position of the vehicle and the video / audio inside the vehicle is transmitted to the transmission destination. You may make it transmit. Here, as a specific example of the situation of the vehicle, the current position of the vehicle specified by the position specifying means such as GPS, the image in the vehicle photographed by the video camera installed in the vehicle, the microphone installed in the vehicle, etc. In-vehicle sound acquired by the vehicle, traffic jam information acquired by the navigation device, route information calculated by the navigation device, and the like. In this way, the status of the vehicle such as the current position of the vehicle can be notified to the outside of the family in real time.

  Some users have many places to visit, such as going to work on a weekday and going out for golf or shopping on the weekend. Therefore, it is conceivable that the transmission destination of the predetermined information is selected based on the current position of the vehicle. Specifically, as in claim 4, the destination information storage means is information indicating “visit destination” which is a place visited by a user such as a company or a golf course in the above-described user information. One or more “information” is stored in association with each other, and each destination information is stored in association with destination information, whereby user information and destination information are stored in association with each other indirectly. Next, the visit destination specifying means specifies the visit destination based on the visit destination information stored in the transmission destination information storage means and the current position of the vehicle specified by the position specifying means. For example, a visit destination that is closest to the current position of the vehicle may be selected. Further, a visit destination existing within a predetermined range such as within a radius of 10 m from the current position of the vehicle may be searched, and the searched visit destination may be selected. In this case, when there are a plurality of searched destinations, the closest destination from the current position of the vehicle may be selected from among the plurality of visited destinations. When the predetermined information is transmitted as described above, the control means is indirectly associated with the user information based on the visit destination information indicating the visit destination specified by the visit destination specifying means. The transmission destination information is read from the transmission destination information storage means, and predetermined information is transmitted to the transmission destination based on the read transmission destination information. As described above, if the transmission destination of the predetermined information is selected based on the current position of the vehicle, the convenience is improved.

  In addition, as shown in Claim 5, the control means in the vehicle status information transmission apparatus according to any one of Claims 1 to 4 can be realized as a program that causes a computer to function. Therefore, the present invention can be realized as a program invention. In the case of such a program, for example, the program is recorded on a computer-readable recording medium such as an FD, MO, DVD-ROM, CD-ROM, or hard disk, and is used by being loaded into a computer and started up as necessary. be able to. In addition, the ROM or backup RAM may be recorded as a computer-readable recording medium, and the ROM or backup RAM may be incorporated into the computer for use.

[Explanation and effect of emergency information transmission process]
Next, emergency information transmission processing executed by the above-described interphone I / F controller 32 will be described with reference to the flowchart of FIG.

  In the first step 201 (hereinafter, “step” is simply referred to as “S”), the battery voltage sensor 21 detects the output power of the in-vehicle battery (not shown) to acquire the state of the battery.

  In subsequent S202, based on the detection signal from the battery voltage sensor 21, it is determined whether or not the state of the battery is good. Here, if the output voltage of the battery is less than the predetermined voltage value (S202: NO), it is determined that the state of the battery is not good, and the communication I / F 31 which is a receiving circuit is turned off to prevent the battery from being consumed. (S204) Return. The “predetermined voltage value” refers to the lower limit value of the output voltage of the in-vehicle battery that can execute various processes by the in-vehicle ECU 3, and is defined in advance by experiments or the like in consideration of other configurations. On the other hand, if the output voltage of the battery is equal to or higher than the predetermined voltage value (S202: YES), it is determined that the battery is in good condition, and the communication I / F 31 that is the receiving circuit is turned on (S203). Then, the process proceeds to S205.

  In S205, it is determined whether or not emergency information is transmitted from the home server 1. Here, if the emergency information is not transmitted from the home server 1 (S205: NO), the process directly returns. On the other hand, if emergency information is transmitted from the home server 1 (S205: YES, “item list sent from home to company” in FIG. 7C corresponds), the emergency information is received (S206), The effect is displayed as an icon on the display 28 (corresponding to “list of information stored in car” in FIG. 7C). Then, the process proceeds to S207.

  In S207, the current position information of the vehicle is acquired. Specifically, the navigation device 35 generates current position information of the vehicle based on the detection signal from the GPS sensor 25 and transmits it to the interphone I / F controller 32.

  In subsequent S208, the current position information of the vehicle from the navigation device 35 and the latitude / longitude information of the “house parking lot (area)” read from the transfer destination information management table (FIG. 5A) stored in the memory 33 are displayed. Based on this, it is determined whether or not the vehicle exists in the parking lot at the user's house. Here, when the vehicle exists in the parking lot of the user's house (S208: YES), it is determined that it is not necessary to notify the user of the emergency information, and the process returns as it is. On the other hand, when the vehicle does not exist in the parking lot of the user's house but exists in another place (S208: NO), the process proceeds to S209.

  In S209, it is determined whether or not the user exists in or near the vehicle. Specifically, based on the detection signal from the ignition key input sensor 22b, it is determined whether or not the user exists in or near the vehicle depending on whether or not the key is inserted into the indoor key cylinder. . Here, when the key is inserted in the indoor key cylinder (S209: YES), it is determined that the user exists in or near the vehicle, and the process proceeds to S210.

In S210, the notification mode is determined as follows, and the emergency information is notified to the user by the notification mode.
(1) Determine the running state of the vehicle. Specifically, the distance from the vehicle to the next curve is calculated based on the vehicle position information from the GPS sensor 25 and the map data from the map data input device. Next, based on the detection signal from the yaw rate sensor 24b, it is determined whether the yaw rate value is greater than or equal to the specified value. The “specified value” refers to a speed value for the vehicle to travel stably, and is specified in advance by experiments or the like. Further, based on the distance from the vehicle to the next curve and the yaw rate value, the vehicle state is determined with reference to the vehicle state management table FIG. Here, as an example, it is assumed that the distance from the vehicle to the next curve is within 300 m, the yaw rate value is greater than or equal to the specified value, and the traveling state corresponds to the symbol “B4”.
(2) Based on the detection signal from the wheel speed sensor 24c, the speed of the vehicle (corresponding to “vehicle speed” in FIG. 4A) is calculated. Here, it is assumed that the speed of the vehicle corresponds to “<20 km / h”.
(3) Based on the vehicle state and the vehicle speed, the notification mode is determined with reference to the notification mode reference table (FIG. 4A). Here, since the traveling state corresponds to the symbol “B4” and the vehicle speed corresponds to “<20 km / h”, the notification mode corresponds to the symbol “A1”.
(4) The emergency information is notified to the user based on the notification mode with reference to the notification mode management table (FIG. 4B). Here, as shown in FIG. 7C, since the notification mode is the symbol “A1,” “icon” indicating that emergency information exists (“information stored in the car” in FIG. 7C). Is displayed on the display 28. In the notification mode, in addition to the display of the “icon” on the display 28 described above, as shown in FIG. 4B, the display 28 displays video from the home server 1 and the speaker 27 or buzzer “ There is a buzzer sound such as “Ping Pawn”, a voice of a visitor from the home server 1, an output such as an announcement prepared in advance.

And after notifying emergency information, it returns.
On the other hand, when the key is not inserted into the indoor key cylinder in the previous S209 (S209: NO), it is determined that the user is not present in or near the vehicle and is located away from the vehicle. The process proceeds to S211.

In S211, the emergency information is transmitted to the transmission destination as follows.
(1) A user who has recently used the vehicle is specified. Specifically, the “key ID” and “user” that have been stored by specifying the user who has recently used the vehicle are read from the memory 33, and the read “user” is the user who has recently used the vehicle. Is identified. As an example, it is assumed here that the “key ID” is the number “112233” and the “user” is “husband”.
(2) Identify the “area” where the vehicle is located. Specifically, based on the position information of the vehicle from the GPS sensor 25 and the latitude and longitude information of each “area” read from the transfer destination information management table (FIG. 5A) stored in the memory 33, the vehicle Identify existing “areas”. In this case, an area existing within a radius of 10 m from the current position of the vehicle is searched, and the searched area is selected. Here, it is assumed that “husband” parks the vehicle in “company parking lot”.
(3) A transmission destination and an initial contact mode are selected, and emergency information is transmitted to the selected transmission destination in the selected initial contact mode. Specifically, based on the transmission destination information management table (FIG. 5A) stored in the memory 33, the “mobile phone number” associated with the identified “user”, “key ID”, and “area” ”And“ initial contact mode ”, and the read“ mobile phone number ”and“ initial contact mode ”are selected as the destination of emergency information and the initial contact mode. Then, emergency information is transmitted to the selected transmission destination via the communication I / F 31 in the selected initial contact mode. In this case, an icon is displayed on the display 28 indicating that there is emergency information to be transmitted (corresponding to “item list to be sent to the company or mobile phone” in FIG. 7C). Here, the user “husband”, the key ID number “ 112233 ”and the cell phone number“ 090-XXX-1 ”associated with the area“ company parking lot ”and the symbol“ D3 ”of the initial contact mode are set as the emergency information transmission destination and the initial contact mode. Then, “only the mail information (of the emergency information) is sent and the remaining information is recorded in the navigation” is sent to the “husband” 's mobile phone number “090-XXX-1”.

After the emergency information is transmitted, the process returns.
Thus, according to the vehicle-mounted ECU 3 of the present embodiment, emergency information can be reliably transmitted to the user even when the user is away from the vehicle.

[Description and effects of intrusion monitoring processing]
Next, intrusion monitoring processing executed by the intrusion / abnormality monitoring apparatus 34 will be described with reference to the flowchart of FIG.

  First, in S301, the locked door is unlocked with the key based on the detection signal from the door key input sensor 22a and the detection signal from a sensor (not shown) that detects opening and closing of the door. In the case, it is determined whether or not the door is unlocked by a key. Here, if the door is not unlocked by the key (S301: NO), it is determined that the door has been unlocked by a person other than the user without using the key and the vehicle has been stolen, and S304 ( (To be described later). On the other hand, when the door is unlocked by the key (S301: YES), the process proceeds to S302.

  In S302, it is determined whether the accessory switch of the vehicle has been turned on by the key based on the detection signal from the ignition key input sensor 22b when the vehicle has started. In this embodiment, whether or not the vehicle has started is determined based on whether or not the vehicle has traveled 3 m or more from the stop state based on the detection signal from the wheel speed sensor 24. Here, when the accessory switch is not turned on by a key (S302: NO), it is determined that the ignition of the vehicle is turned on by a person other than the user without using the key, and the process proceeds to S304 (described later). Transition. On the other hand, when the accessory switch is turned on by the key (S302: YES), the process proceeds to S303.

  In S303, it is determined whether or not the parked vehicle is tilted. In this embodiment, the determination is made based on the detection signal from the yaw rate sensor 24b based on whether or not the vehicle is inclined at least 5 degrees in the front-rear direction or the left-right direction. If the parked vehicle is tilted (S303: YES), it is determined that the vehicle has been stolen by, for example, a truck, and the process proceeds to S304 (described later). On the other hand, when the stopped vehicle does not tilt (S303: NO), the process returns as it is.

  In S304, the interphone I / F controller 32 generates theft information by determining that it has been stolen or destroyed by something other than the user in S301, S302, or S303. This “theft information” is the “cause” of the vehicle being stolen (in S301, it was determined that the door was unlocked without using a key by a person other than the user, or used in S302. It is determined that the ignition of the vehicle has been turned on without a key by a person other than the user, that the vehicle has been stolen by being transported, for example, by a truck in S303), and the vehicle Includes information indicating that the vehicle is stolen, including the “time” at which the car was stolen. Then, the theft information is transmitted to the home server 1 and the mobile phone 4 through the communication I / F 31 together with the position information of the vehicle from the GPS sensor 25 and the in-vehicle image from the in-vehicle monitoring camera 23. Further, when a microphone is provided inside the vehicle and theft information is transmitted, the sound inside the vehicle input to the microphone may be transmitted.

Thus, according to the in-vehicle ECU 3 of the present embodiment, even if the vehicle is stolen, a user or the like can quickly know that fact.
[Explanation and effects of dangerous driving condition monitoring process]
Next, the dangerous traveling state monitoring process executed by the intrusion / abnormality monitoring device 34 will be described with reference to the flowchart of FIG.

First, in step S601, it is determined whether the vehicle is spinning based on the yaw rate value of the vehicle detected by the yaw rate sensor 24b. The yaw rate value φ _{VW of the} vehicle is calculated using the following equation (1).

φ _VW = f ₁ (V _WFR , V _WFL , V _WRR , V _WRL ) (1)
However, since the function f ₁ (V) is generally known as a function for obtaining the estimated yaw rate value from the wheel speed, detailed description thereof is omitted. V _WFR , V _WFL , V _WRR and V _WRL are wheel speeds, FR indicates the front right side, FL indicates the front left side, RR indicates the rear right side, and RL is the rear left side. Is shown.

  If the yaw rate value of the vehicle is greater than 1.2 rad / sec (S601: YES), it is determined that the vehicle is in a dangerous traveling state, and the process proceeds to S605 (described later). The yaw rate value “1.2 rad / sec” is defined in advance by experiments or the like. On the other hand, when the value of the yaw rate of the vehicle is 1.2 rad / sec or less (S601: NO), the process proceeds to S602.

  In S602, it is determined whether the vehicle is suddenly braked based on the vehicle deceleration G calculated based on the vehicle speed detected by the wheel speed sensor 24c. In addition, you may comprise so that the deceleration G may be calculated based on the detection signal from G sensor used for an airbag etc. Here, when the deceleration G is smaller than -1.5G (S602: YES), it is determined that the vehicle is in a dangerous traveling state because the vehicle is suddenly braked, and the process proceeds to S605 (described later). Note that the value “−1.5 G” of the deceleration G is defined in advance by experiments or the like. On the other hand, when the deceleration G is −1.5 G or more (S602: YES), the process proceeds to S603.

  In S603, it is determined whether or not the vehicle has collided based on the vehicle collision G calculated based on the vehicle speed detected by the wheel speed sensor 24c. In addition, you may comprise so that the deceleration G may be calculated based on the detection signal from G sensor used for an airbag etc. Here, when the absolute value of the collision G is larger than 10 G (S603: YES), it is determined that the traveling state is dangerous, and the process proceeds to S605 (described later). The value “10G” of the collision G is defined in advance by experiments or the like. On the other hand, when the absolute value of the collision G is 10 G or less (S603: NO), the process proceeds to S604.

In S604, whether or not the vehicle is meandering is determined based on the amount of deviation calculated by comparing the yaw rate value of the vehicle detected by the yaw rate sensor 24b with the estimated yaw rate value calculated by the navigation device 35. Judgment is as follows.
(A) The yaw rate value φ _{VW of the} vehicle is calculated from the four wheel speeds using the above equation (1).
(B) The estimated yaw rate value φ _RO is calculated. Specifically, first, the vehicle speed V _B is calculated using the following equation (2-1).

V _B = (V _WFR + V _WFL + V _WRR + V _WRL ) / 4 (2-1)
Subsequently, based on the vehicle speed V _B and the curvature radius R _MAP calculated from the map, the estimated yaw rate value φ _RO is calculated using the following equation (2-2).

φ _RO = f ₂ (V _B , R _MAP ) (2-2)
The function f ₂ (V) is generally known as a function for obtaining the estimated yaw rate value from the vehicle speed and the radius of curvature calculated from the map, and thus detailed description thereof is omitted.
(C) A deviation φ _USR between the vehicle yaw rate value φ _VW calculated in the above equation (1) and the estimated yaw rate value φ _RO calculated in (2) is calculated using the following equation (3).

φ _USR = φ _VW −φ _RO (3)
(2) Based on the deviation amount φ _USR calculated by the above equation (3), the rate of change Δφ of the yaw rate value
Is calculated using the following equation (4) to calculate the average absolute value of φ _USR for each Δt.

Δφ = (∫ | φ _VW −φ _RO | dt) / Δt (4)
(E) It is determined whether or not the vehicle is meandering based on the change rate Δφ of the yaw rate value calculated by the above equation (4). Note that the determination criteria are defined in advance by experiments or the like.

  If it is determined that the vehicle is meandering (S604: YES), information indicating that the user is encouraged to take a break is displayed on the display 28 (see FIG. 7A). ”And“ angry ”to express the driving state with the driver ’s expression.) Further, in this case, a nearby parking location may be searched and displayed ((point “P” of “map information” in FIG. 7B is equivalent)), and the process proceeds to S605 (described later). On the other hand, if it is determined that the vehicle is not meandering (S604: NO), the process directly returns.

  In S605, the interphone I / F controller 32 generates information indicating that the vehicle is in a dangerous driving state when it is determined in S601, S602, S603, and S604 that the vehicle is in a dangerous driving state. The information is transmitted to the home server 1 and the mobile phone 4 through the communication I / F 31 together with the position information of the vehicle from the GPS sensor 25 and the in-vehicle image from the in-vehicle monitoring camera 23 (FIG. 7B). ) Display example on the home server 1. The driving state is expressed by the driver's expression such as “smile” or “anger”. Note that when transmitting information indicating that the vehicle is in a dangerous driving state, the traffic information in the vicinity of the vehicle acquired by the navigation device 35 via the communication I / F 31 and the destination calculated by the navigation device 35 are used. Route information (corresponding to “map information” in FIG. 7B) may be transmitted. Further, when a microphone is provided inside the vehicle and information indicating that the vehicle is in a dangerous traveling state is transmitted, the sound inside the vehicle input to the microphone may be transmitted. Further, an estimated arrival time at the destination (corresponding to “time” in FIG. 7B) may be calculated and displayed.

  When emergency information is received from the home server 1 when the vehicle is in a dangerous driving state as described above, information indicating that the vehicle is in a dangerous driving state is generated, and the information is sent to the home server 1. You may make it transmit.

Thus, according to the vehicle-mounted ECU 3 of the present embodiment, it is possible to inform the outside of a family or the like in real time about the vehicle status such as the current position of the vehicle.
