That is, the processing control unit 15 controls the detection command transmission / reception unit 12 and issues a traveling state detection command to the navigation device 2. Then, the processing control unit 15 acquires information indicating the traveling state of the vehicle returned from the navigation device 2 through the detection command transmitting / receiving unit 12.

The processing control unit 15 determines whether or not the vehicle is running according to the acquired information indicating the running state (step S2). When it is determined that the vehicle is not running (the vehicle is stopped), the process control unit 15 proceeds to step S12 described below.

On the other hand, when it is determined that the vehicle is traveling, the processing control unit 15 determines whether or not the own vehicle angle is changing (the vehicle is turning right or left) (step S3). Processing control unit 1
When it is determined that the own vehicle angle is changing, the process proceeds to step S11 described below.

On the other hand, if it is determined that the own vehicle angle is not changing, the processing control unit 15 determines whether the vehicle is greatly accelerating or decelerating (step S4). Processing control unit 15
If it is determined that the acceleration / deceleration is larger than the predetermined value, the process proceeds to step S11 described below.

On the other hand, if it is determined that the vehicle is not greatly accelerating or decelerating, the processing control unit 15 issues a current road state detection command to the navigation device 2 and acquires the current road state according to the returned information (step S5). ).

The processing control unit 15 determines whether or not the own vehicle position is traveling at the caution point according to the acquired current road condition (step S6). That is, the processing control unit 15
Indicates that the current road condition is, for example, within an intersection, at a junction, at the top of a hill, a curve with poor visibility, a continuous curve, and
It is determined whether or not it is the “own vehicle position attention point” indicating the inside of a railroad crossing or the like.

When the processing control unit 15 determines that the vehicle is traveling at the point of interest, the processing proceeds to step S11 described below. On the other hand, if it is determined that the vehicle is not
The processing control unit 15 issues a forward road condition detection command to the navigation device 2, and acquires the forward road condition according to the returned information (step S7).

The processing control unit 15 determines whether or not the vehicle is approaching a caution point ahead in accordance with the acquired road condition ahead (step S8). That is, the processing control unit 15
It is determined whether or not the forward road state is, for example, “approaching a caution point ahead” indicating approaching an intersection, approaching a stop point, approaching a railroad crossing, and the like. If the process control unit 15 determines that the vehicle is approaching the caution point ahead, the process control unit 15 proceeds to step S11 described below.

On the other hand, if it is determined that the caution point is not approaching (the caution point is far, etc.), the processing control unit 15 issues a route guidance state detection command to the navigation device 2 and according to the returned information. The route guidance state is acquired (step S9).

The processing control unit 15 determines whether or not the vehicle is approaching a guidance point ahead in accordance with the acquired route guidance state (step S10). That is, the processing control unit 15
Determines whether or not the route guidance state is, for example, "forward guidance point approach" which indicates approach to a guidance point to be turned left or right.

If the processing control unit 15 determines that the vehicle is approaching the guidance point ahead (steps S3, S4, S6,
(Including the case of "Yes" in S8), the incoming call restriction detection section is set to "ON" (step S11). That is, the processing control unit 15 sets the incoming call restriction detection section to “ON” in order to indicate that the own vehicle is traveling in a place where the incoming call of the mobile phone 4 should be restricted.

On the other hand, if it is determined that the vehicle is not approaching the guidance point ahead (including the case where it is determined that the vehicle is not traveling in step S2), the incoming call restriction detection section is set to "OFF" (step S12). That is, the processing control unit 15 sets the incoming call restriction detection category to “OF” in order to indicate that the vehicle is traveling in a place where it is not necessary to restrict the incoming call of the mobile phone 4.

The current state of controlling the mobile phone 4 (during incoming call restriction or during incoming call reception) is acquired from the incoming call control state stored in the incoming call control state holding unit 16.

The processing control section 15 determines whether or not an incoming call is possible according to the obtained incoming call control state (step S23). When it is determined that the incoming call is not possible (the incoming call is being restricted), the process control unit 15 ends the incoming call control process and returns the process to the above-described detection control process.

On the other hand, if it is determined that a call can be received,
The processing control unit 15 transmits the call state detection command to the mobile phone 4.
The communication status of the mobile phone 4 is acquired according to the returned information (step S24). That is, the processing control unit 15 controls the control command transmission / reception unit 14 and issues a call state detection command to the mobile phone 4. Then, the processing control unit 15 obtains information indicating the call state of the mobile phone 4 (whether or not a call is being made) returned from the mobile phone 4 through the control command transmitting / receiving unit 14.

The processing control unit 15 determines whether or not the mobile phone 4 is in a call according to the acquired call state (step S25). If the process control unit 15 determines that the mobile phone 4 is busy, it terminates the incoming call control process and returns to the above-described detection control process. That is, the processing control unit 15 returns the processing to the detection control processing without controlling the mobile phone 4 to be in the incoming-call-restricted state so as not to disturb the call of the mobile phone 4.

On the other hand, if it is determined that the user is not talking, the processing control unit 15 issues an incoming call restriction command to the mobile phone 4 and controls the mobile phone 4 to be in the incoming call restriction state (step S26).

If it is determined in step S21 that the incoming call restriction detection section is not "ON" (the section is "OFF"), the processing control section 15 changes the incoming call control state to the incoming call control state holding section. 16 (step S2)
7).

The processing control section 15 determines whether or not the incoming call is being restricted according to the obtained incoming call control state (step S28). If the process control unit 15 determines that the incoming call is not being restricted (it is possible to receive a call), the process control unit 15 ends the incoming call control process and returns to the above-described detection control process.

On the other hand, if it is determined that the incoming call is being restricted,
The processing control unit 15 issues a restriction release command to the mobile phone 4 and controls the mobile phone 4 to be in a state where it can receive a call (step S29).

The processing control unit 15 includes the incoming call control state holding unit 1

When the navigation device 2 determines that the vehicle is traveling in any of the above locations, the navigation device 2 generates information indicating the "own position attention point" and returns it to the mobile phone control device 1 (step S58).

On the other hand, if it is determined that the vehicle is not traveling at any point, the navigation device 2 generates information indicating a “normal point” and returns it to the mobile phone control device 1 (step S59).

As described above, the navigation device 2 determines the current road condition in which the own vehicle is traveling in accordance with the current position and the road network information.
The information indicating the "own vehicle position attention point" is transmitted to the mobile phone control device 1

According to the acquired road network information, the navigation device 2 determines whether the vehicle is approaching an intersection ahead (step S73), whether it is approaching a stop point ahead (step S74), and It is determined whether or not the vehicle is approaching the front crossing (step S75).

If it is determined that the vehicle is approaching any of the above points, the navigation device 2 generates information indicating "approaching the point of caution ahead" and returns it to the mobile phone control device 1 (step S76).

On the other hand, if it is determined that the vehicle is not approaching any point, the navigation device 2 generates information indicating "no approach" and returns the information to the portable telephone control device 1 (step S77).

The navigation device 2 acquires road network information corresponding to the current position of the vehicle (step S92). The navigation device 2 acquires the guidance route information stored in advance in the storage unit provided therein (step S93).

The navigation device 2 determines whether the vehicle is approaching the guidance point ahead (step S94).
That is, the navigation device 2 determines, for example, whether or not the vehicle is approaching a guidance point for instructing a right / left turn in accordance with the acquired current position and guidance route information.

If the navigation device 2 determines that the vehicle is approaching the guidance point, it generates information indicating "forward guidance point approach" and returns it to the mobile phone control device 1 (step S95).

On the other hand, if it is determined that the vehicle is not approaching the guidance point, the navigation device 2 generates information indicating "no approach" and returns it to the mobile phone control device 1 (step S96).

As described above, the navigation device 2 specifies the guidance point in front of the own vehicle in accordance with the current position, the road network information, and the guidance route information. Information indicating “approaching the front guidance point” is supplied to the mobile phone control device 1.
