Communication Device
The automobile communicator T11 uses the transmitter T111 and the receiver T112 to communicate with the mobile station apparatus 1. The engine T12 outputs, to a driving wheel (not illustrated), a driving force (torque) that causes the automobile T1 to run. The drive operator T13 includes, for example, an acceleration pedal, a brake pedal, a shift lever, a steering wheel, an odd-form steering, a joystick, and other operators. The drive operator T13 is equipped with a sensor that detects an amount of operation or the presence or absence of operation.
The vehicle sensor T14 includes a speed sensor that detects the speed of the automobile T1, an acceleration sensor that detects acceleration, an azimuth sensor that detects the orientation of the automobile T1, a ranging sensor such as a laser for use in collision avoidance or automatic driving, or other sensors. The camera T16 is a digital camera including a solid-state image sensing device such as a CCD (charge-coupled device) or a CMOS (complementary metal-oxide semiconductor).
The camera T16 is attached to any place on the automobile T1. The camera T16 for example takes an image of an area around the automobile T1 periodically-repeatedly. The configuration information storage T17 has stored therein information on the automobile T1. The information on the automobile T1 includes information indicating that T1 is an automobile and information pertaining to the model.
The acquirer T151 acquires state information pertaining to the state of the engine T12, the state of the drive operator T13, and the state of the vehicle sensor T14. Further, the acquirer T151 acquires image data captured by the camera T16. Further, the acquirer T151 acquires the information on the automobile T1 from the configuration information storage T17. At this time, the acquirer T151 sets “1” as the type information of the automobile T1.
In a case where the acquirer T151 has acquired, from the engine T12, the drive operator T13, or the vehicle sensor T14, information indicating that the automobile T1 is running, the acquirer T151 sets “1” as the first state number. In a case where the acquirer T151 has acquired, from the drive operator T13 or the vehicle sensor T14, information indicating that the automobile T1 is not running, the acquirer T151 sets “2” as the first state number.
A determination as to whether the automobile T1 is running may be based on state information indicating whether the engine T12 is operating. Alternatively, a determination as to whether the automobile T1 is running may be based on state information indicating, for example, that the accelerator has been pressed down on or the brakes have been released.
In a case where the acquirer T151 has acquired, from the vehicle sensor T14, information indicating that the running speed of the automobile T1 is 30 km/h or higher, the acquirer T151 sets “1” as the second state number. In a case where the acquirer T151 has acquired, from the vehicle sensor T14, information indicating that the running speed of the automobile T1 is 10 km/h or higher and less than 30 km/h, the acquirer T151 sets “2” as the second state number. In a case where the acquirer T151 has acquired, from the vehicle sensor T14, information indicating that the running speed of the automobile T1 is 5 km/h or higher and less than 10 km/h, the acquirer T151 sets “3” as the second state number. In a case where the acquirer T151 has acquired, from the vehicle sensor T14, information indicating that the running speed of the automobile T1 is less than 5 km/h, the acquirer T151 sets “4” as the second state number.
In a case where the automobile T1 is not running and a vehicle other than the automobile T1 shows up on the image data thus captured, the acquirer T151 may set “2” as the first state number and set “1” as the second state number. In a case where “2” has been set as the first state number and “1” has been set as the second state number, the acquirer T151 may determine that there is a possibility that the automobile T1 might be rear-ended by another vehicle.
In a case where the automobile T1 is not running and no vehicle other than the automobile T1 shows up on the image data thus captured, the acquirer T151 may set “2” as the first state number and set “2” as the second state number. In a case where “2” has been set as the first state number and “2” has been set as the second state number, the acquirer T151 may determine that there is no possibility that the automobile T1 might be rear-ended by another vehicle. The communication processor T152 controls how the automobile communicator T11 operates. Further, the communication processor T152 exercises control of using the automobile communicator T11 to transmit the type information, the first and second state numbers pertaining to states, and the image data to the mobile station apparatus 1.

In this case, the communication control configuration controller 132 proceeds to step S106-4, in which the communication control configuration controller 132 reads out the communication control configuration number “8” on the basis of the communication control configuration request information table. Then, the communication control configuration controller 132 generates communication control configuration request information containing the communication control configuration number “8”.
