Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
FIG. 1 is a block diagram for explaining the overall configuration of the in-vehicle device system according to the present embodiment. As shown in the figure, an in-vehicle device system (mobile body mounted device system) 1 is mounted on an automobile (movable body) and is integrally mounted on the automobile, such as a car stereo or a car navigation system (mounted on a mobile body). Device) 2 and a portable device (operation input means) 3 such as a mobile phone owned by a passenger of the automobile.
The in-vehicle device 2 includes an operation unit 5 for a user to perform an operation, and a central processing unit (identity determining unit, an arithmetic processing unit for controlling each unit of the in-vehicle device 2 according to an operation input from the operation unit 5. Identity determining unit) 6. The central processing unit 6 is connected to a vehicle speed detection determination unit (moving state determination unit) 7 and a potential detection unit (driver potential detection unit, driver information detection unit) 8. The vehicle speed detection determination unit 7 is connected to a speed signal generation unit 10 and a side brake sensor 11 provided in the automobile. Here, the speed signal generation unit 10 detects the traveling speed of the automobile and generates the speed signal as a vehicle speed pulse, and the side brake sensor 11 determines whether or not the side brake of the automobile is pulled (ON and Detected or turned off). The vehicle speed detection determination unit 7 determines whether the vehicle is running or stopped based on the speed signal output from the speed signal generation unit 10 and the side brake detection signal output from the side brake sensor 11. The result is output to the central processing unit 6. The potential detection unit 8 is connected to a steering electrode unit 12 provided for the steering wheel of the automobile and a shift lever electrode unit 13 provided for the shift lever of the automobile. When the driver holds it, the potential of the driver is detected. Further, the potential detection unit 8 sequentially outputs the driver potential detected in this manner to the central processing unit 6.
The central processing unit 6 is connected to the voice generation / screen display unit 14 and the data transmission / reception unit 15 and transmits a signal for controlling the operation of the voice generation / screen display unit 14 based on the calculation result. In addition, data can be transmitted / received to / from the mobile device 3 via the data transmission / reception unit 15.

  In addition, the mobile device 3 includes an operation unit 20 for a user to perform an operation, and a central processing unit (operation validity determination unit, operation control unit) for controlling each unit of the device in accordance with an operation input from the operation unit 20. 21) In addition to the sound generation / screen display unit 22 controlled by the control signal from the central processing unit 21, the data transmission / reception unit (inquiry information transmission unit) 24, the potential detection unit (operator potential detection means, operator An information acquisition unit) 25 and an electrode unit 26 are provided. The data transmission / reception unit 24 can communicate with not only the other portable device 3 but also the in-vehicle device 2. The potential detection unit 25 is connected to the electrode unit 26 provided in the casing of the mobile device 3. When the operator holds the casing of the mobile device 3, the potential detection unit 25 detects the potential of the operator, The detection result can be output to the central processing unit 21.

Next, the operation of the in-vehicle device system 1 will be described with reference to FIG.
The operation of the in-vehicle device system 1 described below performs an operation input of the in-vehicle device 2 using the mobile device 3, and whether or not the person who performed the operation input on the in-vehicle device 2 side is a driver. This is an operation for determining the validity / invalidity of the operation input in the portable device 3 based on the determination result.
FIG. 2 is a flowchart showing the operation in the in-vehicle device system 1, in which the left column shows the operation in the mobile device 3 and the right column shows the operation in the in-vehicle device 2.
First, in the in-vehicle device system 1, the portable device 3 determines whether or not there is an operation input every predetermined time (step Sa1). That is, the mobile device 3 is in a state of waiting for an output signal from the operation unit 20. When it is determined that an operation input has been made based on an output signal from the operation unit 20, the central processing unit 21 of the portable device 3 detects that the potential of the electrode unit 26 is detected by the potential detection unit 25. An instruction is given (step Sa2). Based on this, the potential detection unit 25 detects the potential of the electrode unit 26 (step Sa3). Thereby, the electric potential which the operator of the portable apparatus 3 has is detected. This potential detection is performed by sampling, for example, 100 potential data in a predetermined period (for example, 1 second).

  Further, in step Sa2, the central processing unit 21 of the mobile device 3 is connected to the central processing unit 6 of the in-vehicle device 2 via the data transmitting / receiving unit 24 and the data transmitting / receiving unit 15 of the in-vehicle device 2. Also, an instruction signal for detecting the potential is transmitted. As a result, the central processing unit 6 of the in-vehicle device 2 outputs an instruction signal for detecting the potential to the potential detection unit 8, and the potential detection unit 8 outputs the steering electrode unit 12 and the shift lever electrode unit 13. The potential is detected and output to the central processing unit 6. Thus, the potential of the driver is detected when the driver is holding the steering wheel or the shift lever, that is, when the driver is driving (step Sb1). This potential detection is also performed by sampling, for example, 100 potential data in a predetermined period (for example, 1 second), similarly to the detection of the potential in the portable device.

When the potential is detected on the portable device 3 side and the on-vehicle device 2 side in this way, the central processing unit 21 of the portable device 3 transmits the potential of the electrode unit 26 of the portable device 3 to the on-vehicle device 2. An inquiry is made as to whether this potential is the same as the driver's potential, that is, whether the operator of the portable device 3 is the same as the driver. In response to this, the central processing unit 6 of the in-vehicle device 2 compares the potentials detected by the potential detection unit 8 and the potential detection unit 25 to determine whether the operator of the portable device 3 and the driver are the same. It is determined whether or not (step Sb2). Here, as a criterion for determining that the operator and the driver of the portable device 3 are the same, (1) both potentials are substantially equal during a predetermined time when the potentials are sampled, and (2) It is conceivable that the state continues for a predetermined time or a predetermined number of sampling times, or (2) even if both potentials are different, their temporal changes are substantially the same.
Further, here, the potential data is compared in consideration of a slight time lag due to wireless communication between the mobile device 3 and the in-vehicle device 2. For this purpose, the correlation is calculated by shifting the potential data to be compared by a predetermined shift time, and the shift time when the correlation becomes maximum is set as a time lag to be considered. When comparing the potential data, the time lag data is shifted in time and the comparison is performed.

Furthermore, the central processing unit 6 of the in-vehicle device 2 returns the determination result in step Sb2 to the mobile device 3 side. The central processing unit 21 of the mobile device 3 determines whether or not the determination result indicates that the operator and the driver of the mobile device 3 are the same (step Sa4). If it is determined that the operation is performed, a signal indicating that the vehicle is running or stopped is transmitted to the in-vehicle device 2 (step Sa5). In response to this, the central processing unit 6 of the in-vehicle device 2 detects whether the vehicle is running or stopped based on the output from the vehicle speed detection determination unit 7 and carries determination information about it. Transmit to the device (step Sb3).
The vehicle speed detection / determination unit 7 determines whether the vehicle is running or stopped as follows.
First, as a condition for determining that the automobile is stopped, any one or a plurality of determination criteria such as the following (1) to (4) are used.
(1) When the speed signal indicates a low speed (for example, 4 km / h).
(2) When the side brake detection signal indicates an ON state, that is, when it indicates that the side brake is applied.
(3) When the speed signal is in a state indicating 0 km / h.
(4) When the speed signal is in a state indicating 0 km / h and this state continues for several seconds (for example, 2 seconds).
Furthermore, any one or more of the following criteria (5) to (8) are used as the conditions for determining the vehicle from the stopped state to the traveling state.
(5) When the speed signal is in a state indicating 0 km / h or more.
(6) When the side brake detection signal indicates an OFF state, that is, when the side brake is released.
(7) When the speed signal reaches a predetermined speed (for example, 4 km / h) or more.
(8) When the speed signal becomes 0 km / h or more and this state continues for several seconds (for example, 2 seconds).

Further, on the mobile device 3 side, it is determined whether or not the vehicle is stopped based on the determination information transmitted from the in-vehicle device 2 (step Sa6). In this case, if it is determined that the vehicle is not stopped, the driver has operated the portable device 3 while the vehicle is running. Therefore, the central processing unit 21 of the portable device 3 is operated by the operator of the portable device 3. An operation invalidity notification is made (step Sa7). This operation invalidation notification is performed by the sound generation / screen display unit 22 operating based on the output signal from the central processing unit 21. On the other hand, if it is determined in step Sa6 that the automobile is stopped, the driving operation is not hindered even if the operator of the portable device 3 and the driver are matched. It is determined that the operation is valid (step Sa8), whereby the portable device 3 and the in-vehicle device 2 perform transmission / reception of various data by wireless communication. Thereby, it becomes possible to perform an operation input to the in-vehicle device 2 using the portable device 3.
Further, if it is determined in step Sa4 that the operator of the mobile device 3 and the driver are not the same, the process proceeds to step Sa8, whereby the mobile device 3 and the in-vehicle device 2 transmit and receive various data. It is performed by wireless communication, and operation input of the in-vehicle device 2 using the mobile device 3 is enabled.

  As described above, in the present embodiment, the identity of the driver of the car and the operator of the mobile device 3 is determined, and the validity / invalidity of the input operation in the mobile device 3 is determined based on this determination. Therefore, when the operator and the driver are different, the input operation can be validated. As a result, it is possible to improve the usability of passengers other than the driver while ensuring safety during traveling.

  Further, based on the moving state of the vehicle determined by the vehicle speed detection determination unit 7 and the identity of the driver of the vehicle and the operator of the portable device 3 determined by the central processing unit 6 of the in-vehicle device 2, the portable device 3. The central processing unit 21 disables the operation input when it is determined that the driver and the operator are the same and the vehicle is moving. The driver can also perform operations, and the usability is good.

In the present embodiment, the potential detection unit 8 of the in-vehicle device 2 detects the potential of the steering electrode unit 12 and the shift lever electrode unit 13, and the electrode unit 26 of the portable device 3 is an operator of the portable device 3. Is transmitted from the data transmission / reception unit 24 to the in-vehicle device 2, and the central processing unit 6 of the in-vehicle device 2 is operated by the driver and the operator of the portable device 3. Therefore, it is possible to easily determine the identity of the driver and the operator. Furthermore, since identity can be determined based on temporal changes in the potentials of the driver and the operator, it is possible to determine identity more accurately.
In addition, the portable device 3 transmits the potential of its own operator to the in-vehicle device 2 and also queries the in-vehicle device 2 for the identity of the own operator and the driver. It is possible to realize a safe portable device 3 in which the operation becomes invalid.

In the above embodiment, other configurations can be adopted without departing from the spirit of the present invention.
For example, in the above embodiment, the mobile device 3 is a mobile phone, but is not limited thereto, and may be a remote controller attached to the in-vehicle device 2 or the like.
Further, in the above embodiment, the determination as to whether or not the operator of the portable device 3 and the driver are the same is made on the in-vehicle device 2 side. You may make it carry out in the apparatus 3 side. In this case, the in-vehicle device 2 detects the potential of the steering electrode unit 12 or the shift lever electrode unit 13 based on a potential detection instruction on the portable device 3 side, and transmits this potential data to the portable device 3. The portable device 3 compares the detected potential of the steering electrode portion 12 or the shift lever electrode portion 13 with the potential data transmitted from the in-vehicle device 2, and based on the result, the validity / invalidity of the operation of the operator is determined. To be judged.

  Moreover, although the said embodiment was an example in the case of operating the vehicle equipment 2 using the portable apparatus 3, it may be made not only to this but to apply this invention when operating a vehicle equipment directly. Good. An example of the in-vehicle device in this case is shown in FIG. The in-vehicle device 2 ′ shown in FIG. 3 is provided with an electrode unit 5a with respect to the operation unit 5, so that the potential is detected by the electrode unit 5a when a vehicle occupant touches the in-vehicle device 2 ′. Is something that can be done. In this in-vehicle device 2 ′, the operator detected by the electrode unit 5a is compared with the potential detected by the steering electrode unit 12 or the shift lever electrode unit 13 so that the operator and the driver of the in-vehicle device 2 ′ are the same. Only when it is determined that the in-vehicle device 2 ′ is not valid, the in-vehicle device 2 ′ determines that the input operation performed in the operation unit 5 is valid. The operator (driver) is notified of the invalid operation.

Moreover, although the said embodiment judged whether operation input to the vehicle equipment 2 by the portable device 3 was valid / invalid, it is not limited to this, The validity / invalidity of the incoming / outgoing operation of the portable device 3 May be determined in the same manner as in the above embodiment. In this case, for example, the mobile device 3 transmits information for inquiring whether the operator is the same as the driver of the vehicle to the in-vehicle device 2 together with the potential data detected in the potential detection unit 25, and the in-vehicle device 2, the identity of the operator of the mobile device 3 and the driver is determined, and the result is returned to the mobile device 3. The mobile device 3 restricts operations such as incoming / outgoing calls based on the return result. You just have to do it.
In this case, data relating to the potential detected by the potential detection unit 8 is transmitted from the in-vehicle device 2 side, and this data is compared with the potential data of the electrode unit 26 detected by the mobile phone 3 side. Then, the identity of the operator and the driver may be determined, and the validity / invalidity of incoming / outgoing calls may be determined in the portable device 3 based on the result.
By adopting such a configuration, when a plurality of passengers have the portable device 3 in the vehicle, only the driver's portable device 3 can restrict incoming calls and outgoing calls. .
Also in this case, the portable device 3 notifies the operator that the operation is invalid by the voice generation / screen display unit 22 when the operation such as the generation of the ringing tone or the transmission is invalidated. It is desirable to do so.

Further, as a criterion for determining the identity of the driver and the operator of the portable device 3, it is also possible to use other human body information such as a fingerprint, an iris, or a vein pattern instead of the potential of the driver and the operator. It is done.
In addition, other configurations may be adopted within a range not departing from the gist of the present invention, and a combination of the above modifications may be adopted.
