Description

  The present invention is applied to a vehicle equipped with a device for controlling or managing a vehicle using a short-range wireless communication function of a mobile phone terminal and installed application software. In particular, the present invention relates to a security management technique using a mobile phone terminal.

  Originally it was a mobile phone terminal that was developed for the purpose of enabling telephone communication while moving, but now, the control unit such as CPU (Central Processing Unit) in the mobile phone terminal is a general purpose computer. The processing capability is comparable to the performance of the application software, and application software can be executed. By utilizing this processing capability, various data communication services using mobile phone terminals are now being carried out, not limited to the category of telephone communication.

  For example, an ECU (Electric Control Unit) mounted on a car communicates with a center provided by a service provider via a mobile phone terminal, so that the center can measure the travel distance, fuel stored in the ECU, and so on. A service has been proposed in which vehicle information related to usage and other maintenance is collected and analyzed, and advice information as required is provided to the user (driver) via the mobile phone terminal (see, for example, Patent Document 1 or 2). ). Or the security control system of the vehicle using the authentication function of a mobile phone terminal is proposed (for example, refer to patent documents 3 or 4).

  Here, a configuration and a procedure for connecting the mobile phone terminal and the vehicle-mounted ECU will be described with reference to FIG. As shown in FIG. 8, the vehicle 23 is equipped with a mobile phone terminal connection unit 13 for connecting the ECU 15 and the mobile phone terminal 19.

The registered contents can be confirmed by the display unit 14.

  The mobile phone terminal authentication unit 9 always or periodically determines whether or not the mobile phone terminal 19 whose identification information is registered in the identification information registration unit 17 exists in the vehicle or in the vicinity of the vehicle by short-range wireless communication. Monitor. For example, when Bluetooth is used for short-range wireless communication, the range that can be monitored is a distance within approximately 10 m from the mobile phone terminal connection unit 13.

  Since Bluetooth is a widely used communication technology, detailed description is omitted. Needless to say, when the mobile phone terminal 19 is in a power-off state, the presence of the mobile phone terminal 19 in or near the vehicle is equivalent to the absence.

  When the mobile phone terminal authentication unit 9 detects the presence of the mobile phone terminal 19 whose identification information is registered in the identification information registration unit 17, the connection processing unit 18 performs a connection process between the mobile phone terminal 19 and the ECU 15.

  When the mobile phone terminal 19 and the ECU 15 are thus connected, the ECU 15 and the mobile phone terminal 19 communicate with each other to collect predetermined information, and based on the predetermined information, predetermined operations such as operation management and security control are performed. Perform the process. Further, the mobile phone terminal 19 is connected to the server 22 via the base station 20 and the network 21, and can communicate with the server 22.

  In FIG. 8, only the configuration necessary for connection between the ECU 15 and the mobile phone terminal 19 is illustrated, and the configuration necessary for providing various services is omitted.

  The service forms using the mobile phone terminals described above are classified into operation management (Patent Document 1 or 2) and security control (Patent Document 3 or 4). Conventionally, in order to realize these different service forms, different system configurations are used.

  Therefore, if it is going to implement | achieve the system which has the function of both operation management and security control using a prior art, there is nothing other than making it the structure which combined two different system structures simply. This complicates and enlarges the system configuration.

  The present invention is made under such a background, and is a vehicle control device capable of simplifying a system configuration while realizing both functions of operation management and security control using a mobile phone terminal. The purpose is to provide.

  Whether the mobile phone terminal is used for vehicle operation management or security control, any use of the mobile phone terminal as a part of the system configuration of the vehicle After authenticating it, the ECU mounted on the vehicle and the mobile phone terminal must be connected. Therefore, it is an indispensable condition to authenticate and detect whether or not a legitimate mobile phone terminal to be connected to the ECU exists in or near the host vehicle based on the identification information of the mobile phone terminal.

  The present invention pays attention to this point, and also performs security control using a mobile phone terminal used for other purposes such as operation management, according to the correspondence between the state of the vehicle and the detection state of the mobile phone terminal. It is characterized by doing so.

  That is, the present invention communicates with the ECU mounted on the vehicle to collect predetermined information and collect identification information for authenticating a specific mobile phone terminal that performs predetermined processing based on the predetermined information. One or a plurality of registration means, and mobile phone terminal authentication for detecting whether or not a specific mobile phone terminal whose identification information is registered in the registration means exists in or near the own vehicle based on the identification information And a vehicle control device.

  Here, the feature of the present invention is that the specific mobile phone terminal is detected by the mobile phone terminal authentication means together with detection of getting off of the driver by the getting-off detection means by the getting-off detection means for detecting the getting-off of the driver. Means for locking the own vehicle when it is detected that the vehicle is not present in or near the own vehicle for a predetermined time or more, and the mobile phone terminal authentication means in the state where the own vehicle is locked. When the presence of the telephone terminal is detected in the vicinity of the own vehicle and the sensor means for detecting the operation of the door knob includes a means for unlocking the own vehicle when the operation of the door knob is detected.

  The getting-off detection means determines that the vehicle is getting off, for example, when the cab door is opened / closed after the vehicle that has been running has stopped or when the cab door is opened / closed after the engine is stopped.

  According to this, it is possible to realize security control for locking or unlocking a vehicle by using a mobile phone terminal used for other purposes such as operation management as it is.

  Further, a parking detection means for detecting the parking state of the vehicle, and an alarm when both the detection of the parking state of the vehicle by the parking detection means and the detection of the specific mobile phone terminal by the mobile phone terminal authentication means are performed. A warning issuing means is provided.

  According to this, it is possible to avoid a situation in which the driver forgets to leave the specific mobile phone terminal used as the second key of the vehicle in the driver's cab and gets off.

  The parking detection means determines that the vehicle is parked, for example, when a stop of a vehicle that has been traveling so far is detected or when an engine stop is detected.

  Further, means for switching between a normal driving mode and a strict driving mode including a vehicle speed limit according to a predetermined condition is provided, and the predetermined condition is determined when the vehicle is in the normal driving mode. Thus, it is detected that the specific mobile phone terminal does not exist in the vehicle or in the vicinity of the vehicle for a predetermined time or longer.

  According to this, when a person who does not have the specific mobile phone terminal is driving, the vehicle is substantially prevented from being stolen by setting a strict driving mode including a vehicle speed limit. be able to. For example, if the vehicle speed limit is 10 km / h or less, escape is impossible.

  Here, the extremely low speed driving is possible because the parking lot manager who does not have the specific mobile phone terminal drives the vehicle in order to change the parking position of the vehicle in the parking lot. This is because there is a possibility that even if the vehicle is stolen, it is not desirable to prevent the traveling required for a crossing or crossing an intersection for traffic safety.

  In addition, if the vehicle including the specific mobile phone terminal is stolen, the criminal driving mode is not set, but the criminal confirms that the position of the vehicle is specified by the location registration function or the GPS function of the mobile phone terminal. Because you are familiar with it, be sure to take measures such as turning off the power of the mobile phone terminal, discarding the mobile phone terminal, or breaking the mobile phone terminal.

  As a result, a state in which the specific mobile phone terminal is not present in the vehicle or in the vicinity of the vehicle is detected, and at this time, it is possible to switch to the strict driving mode.

  The mobile phone terminal authentication means may further comprise an alarm issuing means for issuing an alarm when the identification information of the mobile phone terminal detected continuously for a predetermined time or more is unregistered identification information.

  According to this, when the criminal who has stolen the vehicle possesses his / her mobile phone terminal, an alarm can be issued by detecting the identification information of the criminal's mobile phone terminal. Alternatively, the warning may be issued, or the warning mode may be switched to the above-mentioned strict driving mode.

  According to the present invention, the system configuration can be simplified while realizing the functions of both operation management and security control using a mobile phone terminal.

(First Example)
The vehicle control apparatus of the first embodiment will be described with reference to FIGS. 1 to 3 and FIG. FIG. 1 is a block diagram of the vehicle control apparatus of this embodiment. FIG. 2 is a flowchart showing a procedure for detecting getting off. FIG. 3 is a flowchart showing a locking / unlocking control procedure.

  In the present embodiment, as shown in FIG. 8, communication is made with the ECU 15 mounted on the own vehicle to collect predetermined information, and a specific mobile phone terminal 19 that performs predetermined processing based on the predetermined information is authenticated. Whether or not the specific mobile phone terminal 19 registered in the identification information registration unit 17 and the specific information registered in the identification information registration unit 17 exists in or near the own vehicle. It is a vehicle control apparatus provided with the mobile telephone terminal authentication part 9 detected based on the said identification information.

  Here, the feature of the present embodiment is that the parking detection unit 4 that detects the parking state of the vehicle, the getting-off detection unit 6 that detects the getting-off of the driver, and of the getting-off of the driver by the getting-off detection unit 6. When the mobile phone terminal authentication unit 9 detects that the specific mobile phone terminal 19 does not exist in the vehicle or in the vicinity of the vehicle when the mobile phone terminal authentication unit 9 detects that the vehicle is not in the vehicle or in the vicinity of the vehicle, the vehicle is locked. When the mobile phone terminal authentication unit 9 detects the presence of a specific mobile phone terminal 19 in the vicinity of the vehicle and the door knob switch 8 that detects the operation of the door knob detects the operation of the door knob, There is a locking / unlocking control unit 7 for unlocking.

  Furthermore, the present embodiment includes an alarm unit 10 that issues an alarm when both the detection of the parking state of the vehicle by the parking detection unit 4 and the detection of the specific mobile phone terminal 19 by the mobile phone terminal authentication unit 9 are performed. .

  Next, the getting-off detection procedure by the parking detector 4 and the getting-off detector 6 will be described with reference to FIG. As shown in FIG. 2, the parking detector 4 monitors the engine speed information from the engine speed sensor 1, the vehicle speed information from the vehicle speed sensor 2, and the ON / OFF state of the key switch 3 (S1). Parking can be detected by detecting a state in which the engine speed is zero or a key switch is turned off in the state of 0 km / h. Alternatively, parking may be detected including parking in an idling state where the vehicle speed is 0 km / h but the engine speed is not zero and the key switch is not OFF (S2).

  This parking detection procedure is an example, and the parking detection procedure is not directly related to the present invention, so any parking detection procedure can be applied to the present invention.

  At this time, in order to prevent the driver from leaving the mobile phone terminal 19 in the vehicle, the alarm unit 10 is instructed to issue a misplacement prevention alarm (S3).

  When the alarm unit 10 receives a misplacement alarm issuing instruction from the locking / unlocking control unit 7, the alarm unit 10 issues an alarm. The alarm is issued by sounding a speaker provided in the driver's cab or blinking a lamp. Or you may sound a horn. Alternatively, it is conceivable to use a speaker or a lamp provided in the mobile phone terminal 19. Since any method for issuing an alarm is not directly related to the present invention, any method may be used.

  Following the parking detection, the ON / OFF state of the door switch 5 is monitored (S4), and when the opening / closing of the door is detected (S5), it is determined that the driver gets off (S6). Note that the getting-off detection procedure in FIG. 2 is an example, and the getting-off detection procedure is not directly related to the present invention, so any getting-off detection procedure can be applied to the present invention.

  Next, the locking / unlocking control procedure by the locking / unlocking control unit 7 will be described with reference to FIG. As shown in FIG. 3, the locking / unlocking control unit 7 monitors the getting-off detection information of the getting-off detection unit 6 (S10), and when getting-off is detected (S11), subsequently, the mobile phone terminal authentication unit 9 Terminal presence / absence information is monitored (S12), and if the registered mobile phone terminal 19 does not exist in the vehicle or in the vicinity of the vehicle for a predetermined time or longer (S13), it is locked (S14).

  The locking / unlocking control unit 7 monitors the doorknob switch 8 after the locking is performed (S15), and the doorknob switch 8 is operated when the doorknob switch 8 transitions from the OFF state to the ON state. It is detected that it has been broken (S16). Further, the terminal presence / absence information from the mobile phone terminal authentication unit 9 is monitored (S17), and when it is detected that the registered mobile phone terminal 19 exists in the vicinity of the own vehicle (S18), the driver tries to get on. Since it can be determined that it is set to be unlocked (S19).

  Needless to say, when the mobile phone terminal 19 is in a power-off state, the presence of the mobile phone terminal 19 in or near the own vehicle is equivalent to the absence of the mobile phone terminal 19. When the power is cut off due to a disconnection, etc., and the driver leaves the mobile phone terminal 19 forgotten in the car, the lock is performed normally, but the driver tries to get on again. Sometimes, the mobile phone terminal 19 is not owned, and unlocking becomes difficult. In order to avoid such a situation, it is desirable that locking and unlocking with a conventional key have priority over locking and unlocking with the mobile phone terminal 19.

(Second embodiment)
A vehicle control apparatus according to a second embodiment will be described with reference to FIGS. FIG. 4 is a block diagram of the vehicle control apparatus of this embodiment. FIG. 5 is a flowchart showing a traveling mode switching procedure.

  The present embodiment includes a travel mode switching unit 11 that switches between a normal travel mode and a strict guard mode including a vehicle speed limit according to a predetermined condition. The predetermined condition is that the mobile phone terminal authentication unit 9 detects that the specific mobile phone terminal 19 does not exist in or near the vehicle for a predetermined time or longer when the vehicle is in the normal travel mode. This is a condition.

  Next, the travel mode switching procedure will be described with reference to FIG. The travel mode switching unit 11 monitors the terminal presence / absence information from the mobile phone terminal authentication unit 9 (S30), and the mobile phone terminal 19 registered in the identification information registration unit 17 continues in the vehicle for a predetermined time or longer. When it is detected that the vehicle does not exist (S31) and is currently in the normal travel mode (S32), the mode is switched to the strict guard mode (S33). At the time of this switching, it is desirable to slowly decelerate in consideration of the safety of surrounding traffic.

  Here, the strict driving mode is a mode in which, for example, the vehicle can run only at a speed of 10 km or less. As a result, when a person who does not have the mobile phone terminal 19 tries to drive the vehicle, the vehicle can move only at a very low speed, and theft of the vehicle can be substantially avoided.

  As described above, extremely low speed driving is possible because the parking lot manager who does not have a specific mobile phone terminal 19 drives the vehicle in order to change the parking position of the vehicle in the parking lot. This is because even if the vehicle is stolen, it is not desirable to prevent even the traveling required for a crossing or crossing an intersection for traffic safety.

  If the vehicle 23 including the specific mobile phone terminal 19 is stolen, the strict driving mode is not entered, but the location of the stolen vehicle 23 is specified by the location registration function or the GPS function of the mobile phone terminal 19. Since the criminal knows that, the mobile phone terminal 19 is turned off, the mobile phone terminal 19 is discarded, and the mobile phone terminal 19 is destroyed.

  As a result, a state in which the specific mobile phone terminal 19 is not present in the vehicle's own vehicle or in the vicinity of the vehicle's own vehicle is detected.

(Third embodiment)
A vehicle control apparatus according to a third embodiment will be described with reference to FIGS. FIG. 6 is a block diagram of the vehicle control apparatus of this embodiment. FIG. 7 is a flowchart showing an alarm issuing procedure.

  The present embodiment includes an alarm unit 10 that issues an alarm when the identification information of the mobile phone terminal that is continuously detected by the mobile phone terminal authentication unit 9 for a predetermined time or longer is unregistered identification information.

  The mobile phone terminal authentication unit 9 in this embodiment not only detects whether or not a specific mobile phone terminal 19 registered in the identification information registration unit 17 exists in or near the vehicle, but also includes identification information. Has a function that also detects whether or not an unregistered mobile phone terminal exists in or near the host vehicle, and a mobile phone terminal whose identification information is not registered exists in or near the host vehicle Is output to the alarm unit 10 as unregistered terminal detection information.

  Next, an alarm issuing procedure will be described with reference to FIG. As shown in FIG. 7, the alarm unit 10 monitors unregistered terminal detection information from the mobile phone terminal authentication unit 9 (S40), an unregistered terminal is detected (S41), and the detection state continues for a predetermined time. In the case (S42), an alarm is issued or the mode is switched to the strict patrol mode described in the second embodiment (S43).

  The alarm condition setting unit 12 can set conditions for issuing an alarm such as the predetermined time. For example, in order to avoid a situation where a pedestrian carrying a mobile phone terminal passes through the vicinity of the own vehicle and erroneously issues an alarm, for example, the predetermined time may be set to 1 minute or more. Alternatively, by setting the key switch to be in the ON state or the vehicle speed not being 0 km / h as a condition for issuing an alarm, a plurality of mobile phone terminals each possessing a different mobile phone terminal in the vicinity of the parked vehicle It can be avoided that a warning is erroneously issued when two or more drivers are talking.

(Example summary)
In the above embodiment, for easy understanding, locking / unlocking control is described in the first embodiment, traveling mode switching control is described in the second embodiment, and unregistered mobile phone terminal detection is performed in the third embodiment. Although the alarm control has been described, it can be easily analogized that an apparatus configuration in which these controls are integrated into one can be obtained.

  According to the present invention, since the security control function can be realized by using the authentication function of the mobile phone terminal mounted on the vehicle, even when the mobile phone terminal is used for other purposes such as operation management. Since security control can be implemented, further enhancement of vehicle-related services using mobile phone terminals can be achieved.

  In addition, according to the present invention, when a criminal performs an action such as turning off the power of the mobile phone terminal, discarding the mobile phone terminal, or breaking the mobile phone terminal, or switching to a strict driving mode, etc. The anti-theft measures can be taken, so there is no worry that the external reporting device or antenna will be invalidated when it is destroyed by the criminal like the conventional anti-theft system, which is larger than the conventional An anti-theft effect can be obtained.
