First, the detailed functional configuration of the vehicle 100 will be described.
The engine 101 is composed of a known internal combustion engine, and outputs power using fuel stored in the fuel tank 114. The engine 101 is driven under the control of the ECU 122. The power output from the engine 101 drives the generator 102.
The generator 102 is electrically connected to the motor 104 via the first inverter 103.

Further, the output control unit 207e outputs the usable number of times and the usable time of the electric appliance calculated by the calculation unit 207d to the display unit 204 such that the usable number of times and the usable time are displayed in the vicinity of the electric appliance shown in the captured image.
The detection unit 207f executes a detection process of detecting the electric appliance by applying a known template matching or the like to the captured image corresponding to the image data based on the image data acquired by the acquisition unit 207a and the template information stored in the template information storage unit 206c.
Next, a process executed by the communication equipment 200A will be described.
As shown in
Steps S202 to S208 respectively correspond to steps S101 to S107 in
In step S210, the determination unit 207b determines whether the imaging device 202 has captured an image. When the determination unit 207b determines that the imaging device 202 captures an image (step S210: Yes), the communication equipment 200A proceeds to step S211 that will be described later. On the other hand, when the determination unit 207b determines that the imaging device 202 does not capture an image (step S210: No), the communication equipment 200A ends this process.
In step S211, the acquisition unit 207a acquires the image data generated by the imaging device 202.
Subsequently, the detection unit 207f executes the detection process of detecting the electric appliance by applying a known template matching or the like to the captured image corresponding to the image data based on the image data acquired by the acquisition unit 207a and the template information stored in the template information storage unit 206c (step S212).
After that, the determination unit 207b determines whether the detection unit 207f can detect the electric appliances from the captured image P1 (step S213). When the determination unit 207b determines that the detection unit 207f can detect the electric appliances from the captured image P1 (step S213: Yes), the communication equipment 200A proceeds to step S214 that will be described later. On the other hand, when the determination unit 207b determines that the detection unit 207f cannot detect the electric appliances from the captured image P1 (step S213: No), the communication equipment 200A ends this process.
Subsequently, in step S214, the calculation unit 207d calculates at least one of the usable number of times and the usable time of each electric appliance detected by the detection unit 207f based on the electric appliances detected by the detection unit 207f and the electric appliance information stored in the electric appliance information storage unit 206b.
Subsequently, the output control unit 207e outputs the usable number of times and the usable time of each electric appliance calculated by the calculation unit 207d to the display unit 204 such that the usable number of times and the usable time are displayed in the vicinity of the corresponding electric appliance shown in the captured image (step S215).
According to the second embodiment described above, the same effect as that of the first embodiment can be achieved, that is, the user can understand the power supply information related to the power supply by the secondary battery 106 mounted on the vehicle 100.
Further, according to the second embodiment, the calculation unit 207d calculates at least one of the usable number of times and the usable time of each electric appliance detected by the detection unit 207f based on the electric appliance detected by the detection unit 207f and the electric appliance information stored in the electric appliance information storage unit 206b. After that, the output control unit 207e outputs the usable number of times and the usable time of each electric appliance calculated by the calculation unit 207d to the display unit 204 such that the usable number of times and the usable time are displayed in the vicinity of the corresponding electric appliance shown in the captured image. With this configuration, the user can intuitively understand the usable number of times or the usable time of the electric appliance in real time when the user uses the electric appliance via the in-vehicle outlet 112 of the vehicle 100.
In the second embodiment, the output control unit 207e outputs the data to the display unit 204 by superimposing the usable number of times and the usable time of the electric appliance calculated by the calculation unit 207d on one captured image such that the usable number of times and the usable time are displayed in the vicinity of the electric appliance captured in the captured image. However, for example, the output control unit 207e may output data to the display unit 204 by superimposing the usable number of time and the usable time of the electric appliance calculated by the calculation unit 207d on a video such that the usable number of times and the usable time are displayed in the vicinity of the electric appliance captured in the captured image.
