DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (First embodiment)

[0017] FIG. 1 is a diagram showing a first embodiment of an information processing system of the present invention. As shown in FIG. 1, the information processing system in this embodiment has a vehicle 100 and an information processing device 200. The vehicle 100 and the information processing device 200 are connected to each other via a communication network 300. The connection between the vehicle 100 and the information processing device 200 and the communication network 300 may be via wireless communication or via wired communication. In addition, the vehicle 100 and the information processing device 200 may be directly connected to each other so as to be able to communicate with each other. The number of vehicles 100 is not limited to one, and may be multiple.

[0018] The vehicle 100 is a vehicle that can be remotely driven without a driver on board, based on operations from the information processing device 200. The vehicle 100 is, for example, a vehicle that transports users who use the present system, such as a bus or taxi that runs on a road.

[0019] The information processing device 200 is a device installed in a facility such as a control center that manages and controls the entire system, and is operated by an administrator who manages and monitors the system or an operator who operates the system.

[0020] Fig. 2 is a diagram showing an example of components provided in the vehicle 100 shown in Fig. 1. As shown in Fig. 2, the vehicle 100 shown in Fig. 1 has a sensor 110, a detection signal transmission unit 120, and a driving control unit 130. Note that Fig. 2 shows only main components related to this embodiment among the components provided in the vehicle 100 shown in Fig. 1.

[0021] The sensor 110 detects obstacles around the vehicle 100. The sensor 110 is attached to the vehicle 100, but the attachment position is not specified. The sensor 110 may be a camera that captures the surroundings of the vehicle 100, or may be a sensor that uses transmission and reception of laser light, or a sensor that detects obstacles using electromagnetic waves or ultrasonic waves. The sensor 110 may be a sensor that detects an impact level that indicates the strength of an impact from an obstacle, or may be a sensor that detects the size of the obstacle or the distance from the vehicle 100 to the obstacle. Here, the obstacle is an object that impedes the travel of the vehicle 100, and is not limited to a fixed object, but also includes a moving object. In addition, the obstacle also includes an object that may hinder the safety of a user who uses the vehicle 100. In addition, when the sensor 110 detects an obstacle, it notifies the detection signal transmission unit 120 of the detection. While the sensor 110 detects an obstacle, it continues to notify the detection signal transmission unit 120 of the detection.

[0022] When the detection signal transmitting unit 120 is notified by the sensor 110 that an obstacle has been detected, the detection signal transmitting unit 120 transmits a predetermined detection signal to the information processing device 200. The detection signal transmitted by the detection signal transmitting unit 120 may be one that can be recognized between the detection signal transmitting unit 120 and the information processing device 200 as an indication that the sensor 110 has detected an obstacle, and the signal format and communication method are not particularly specified. The detection signal may also include information indicating the content of the detected obstacle or the content of the detection, for example, the impact level, the size of the obstacle, or the distance to the obstacle.

[0023] The driving control unit 130 controls the driving of the vehicle 100. The driving control unit 130 controls the driving of the vehicle 100 based on an instruction signal transmitted from the information processing device 200. The instruction signal will be described in detail later.

[0024] Although not shown in FIG. 2, the vehicle 100 may be equipped with a camera. This camera captures an image of the field of view from the driver's seat of a typical vehicle, and transmits image data indicating the captured image to the information processing device 200 in real time. The vehicle 100 may also be equipped with a location information acquisition means for acquiring location information indicating the location of the vehicle 100. This location information acquisition means acquires the location information of the vehicle 100 by using, for example, a GPS (Global Positioning System) function. The location information acquisition means transmits the acquired location information to the information processing device 200.

[0025] Fig. 3 is a diagram showing an example of components included in the information processing device 200 shown in Fig. 1. As shown in Fig. 3, the information processing device 200 shown in Fig. 1 has an operation receiving unit 210, a database 220, an instruction signal transmitting unit 230, and a transmission control unit 240. Note that Fig. 3 shows only main components related to this embodiment among the components included in the information processing device 200 shown in Fig. 1.

[0026] The operation reception unit 210 receives an operation from outside. The operation reception unit 210 is a means capable of inputting information such as an operation button, an operation panel such as a touch panel, a keyboard, a mouse, etc. The operation reception unit 210 notifies the instruction signal transmission unit 230 of the received operation. For example, when the operation reception unit 210 is an operation button, it notifies the instruction signal transmission unit 230 which operation button has been selected. In this case, the operation reception unit 210 outputs to the instruction signal transmission unit 230 the operation button identification information assigned to the selected operation button among the operation button identification information assigned in advance to each individual operation button.

[0027] The database 220 stores the operation received by the operation reception unit 210 and the content of the instruction given by the instruction signal transmission unit 230 to the vehicle in advance in association with each other. FIG. 4 is a diagram showing an example of the association stored in the database 220 shown in FIG. 3. In the example shown in FIG. 4, the operation reception unit 210 is an operation button. In the example shown in FIG. 4, the database 220 shown in FIG. 3 stores information indicating the operation button and information indicating the instruction content in advance in association with each other. The operation button is operation button identification information for identifying each of the multiple operation buttons provided as the operation reception unit 210. The operation button identification information is information that is given in advance to each of the multiple operation buttons provided as the operation reception unit 210, and is output from the operation reception unit 210 to the instruction signal transmission unit 230 when the operation button is operated. The operation button identification information may be any information that can identify the operation button, and may be a combination of letters and numbers. The instruction content is information indicating the content of the instruction included in the instruction signal transmitted by the instruction signal transmission unit 230 to the vehicle 100.

[0028] As shown in FIG. 4, the database 220 stores an operation button "A" and an instruction content "accelerate" in association with each other. This indicates that when the operation button identification information of "A" is output from the operation reception unit 210 to the instruction signal transmission unit 230, the instruction signal transmission unit 230 instructs the vehicle 100 to "accelerate". In addition, the database 220 stores an operation button "B" and an instruction content "deceleration" in association with each other. This indicates that when the operation button identification information of "B" is output from the operation reception unit 210 to the instruction signal transmission unit 230, the instruction signal transmission unit 230 instructs the vehicle 100 to "decelerate". In addition, the database 220 stores an operation button "C" and an instruction content "keep moving" in association with each other. This indicates that when the operation button identification information of "C" is output from the operation reception unit 210 to the instruction signal transmission unit 230, the instruction signal transmission unit 230 instructs the vehicle 100 to "keep moving". Furthermore, the database 220 stores an operation button "D" and an instruction content "stop" in association with each other. This indicates that when the operation button identification information of "D" is output from the operation reception unit 210 to the instruction signal transmission unit 230, the instruction signal transmission unit 230 instructs the vehicle 100 to "stop." In addition to those shown in FIG. 4, the instruction content may include operations that are generally performed when driving a vehicle, such as "sudden stop," "slow down," "turn on the right turn indicator," "turn on the left turn indicator," and "turn on the emergency flasher."

[0029] The instruction signal transmitting unit 230 transmits an instruction signal to the vehicle 100 based on the notification from the operation accepting unit 210. Specifically, the instruction signal transmitting unit 230 reads out, from the database 220, the instruction content associated with the operation button identification information output from the operation accepting unit 210, and transmits, to the vehicle 100, an instruction signal indicating the read instruction content.

[0030] When a detection signal is transmitted from the vehicle 100, the transmission control unit 240 controls the transmission of the instruction signal from the instruction signal transmission unit 230. Specifically, when a detection signal is transmitted from the vehicle 100, the transmission control unit 240 stops the transmission from the instruction signal transmission unit 230 of an instruction signal indicating an instruction to run the vehicle 100. The fact that a detection signal is transmitted from the vehicle 100 means that an obstacle has been detected around the vehicle 100. In that case, it may be dangerous to continue running the vehicle 100 as it is, so it is necessary to stop the running of the vehicle 100. For example, when a detection signal is transmitted from the vehicle 100, the transmission control unit 240 stops the transmission from the instruction signal transmission unit 230 of an instruction signal indicating an instruction to increase the running speed of the vehicle 100. Furthermore, when a detection signal is transmitted from the vehicle 100, the transmission control unit 240 stops the transmission from the instruction signal transmission unit 230 of an instruction signal indicating an instruction to maintain the running speed of the vehicle 100.

[0031] Furthermore, when image data is transmitted from the vehicle 100, the information processing device 200 displays the image data on the monitor. Furthermore, when position information is transmitted from the vehicle 100, the information processing device 200 displays a position indicating the position information on the monitor. This monitor may be provided inside the information processing device 200 or may be provided outside the information processing device 200.

[0032] The following describes a remote operation control method in the information processing system shown in Fig. 1. Fig. 5 is a sequence diagram for explaining an example of a remote operation control method in the information processing system shown in Fig. 1.

[0033] When the operation reception unit 210 of the information processing device 200 receives an operation from the outside (step S1), the operation reception unit 210 outputs identification information for identifying the operation (for example, the above-mentioned operation button identification information) to the instruction signal transmission unit 230. The instruction signal transmission unit 230 reads out the instruction content associated with the identification information from the database 220 using the identification information output from the operation reception unit 210 as a search key (step S2). The instruction signal transmission unit 230 transmits an instruction signal indicating the instruction content read out from the database 220 to the vehicle 100 (step S3). The transmission of the instruction signal is continued at a predetermined cycle unless the operation received by the operation reception unit 210 is changed. When the instruction signal is transmitted from the information processing device 200, the traveling control unit 130 of the vehicle 100 controls the traveling of the vehicle 100 according to the instruction content indicated by the transmitted instruction signal (step S4).

[0034] Also, it is determined whether the sensor 110 has detected an obstacle (step S5). This determination process is always performed. When the sensor 110 detects an obstacle, the sensor 110 notifies the detection signal transmission unit 120 that an obstacle has been detected. Then, the detection signal transmission unit 120 transmits a detection signal to the information processing device 200 (step S6). When the detection signal is transmitted from the detection signal transmission unit 120, the transmission control unit 240 of the information processing device 200 controls (stops) the transmission of the instruction signal from the instruction signal transmission unit 230 (step S7).

[0035] When a detection signal is transmitted from the detection signal transmitting unit 120, the transmission control unit 240 may not only stop transmitting the instruction signal, but may also transmit to the vehicle 100 an instruction signal indicating an instruction to stop or slow down the traveling of the vehicle 100. Furthermore, when no instruction signal is transmitted from the instruction signal transmitting unit 230 for a predetermined time, the traveling control unit 130 may stop the traveling of the vehicle 100.

[0036] Thus, in this embodiment, the information processing device 200 that remotely controls the traveling of the vehicle 100 transmits to the vehicle 100 an instruction signal that controls the traveling of the vehicle 100 based on an operation received from outside, and while the vehicle 100 is traveling according to the instruction signal, if the sensor 110 mounted on the vehicle 100 detects an obstacle around the vehicle 100, it transmits a detection signal to the information processing device 200, and the information processing device 200 that receives the detection signal stops transmitting the instruction signal. This allows the vehicle that is remotely controlled to travel safely. (Second embodiment)

[0037] Fig. 6 is a diagram showing a second embodiment of the information processing system of the present invention. As shown in Fig. 6, the information processing system in this embodiment has a vehicle 101 and an information processing device 201. The vehicle 101 and the information processing device 201 are connected to each other via a communication network 300. The connection between the vehicle 101 and the information processing device 201 and the communication network 300 may be via wireless communication or via wired communication. In addition, the vehicle 101 and the information processing device 201 may be directly connected to each other so as to be able to communicate with each other. The number of vehicles 101 is not limited to one, and may be multiple.

[0038] The vehicle 101 is a vehicle that can be remotely driven without a driver on board, based on operations from an information processing device 201. The vehicle 101 is, for example, a vehicle that transports users who use this system, such as a bus or taxi that runs on a road.

[0039] The information processing device 201 is a device installed in a facility such as a control center that manages and controls the entire system, and is operated by an administrator who manages and monitors the system or an operator who operates the system.

[0040] FIG. 7 is a diagram showing an example of components provided in the vehicle 101 shown in FIG. 6. As shown in FIG. 7, the vehicle 101 shown in FIG. 6 has a sensor 110 and a driving control unit 131. Note that FIG. 7 shows only the main components related to this embodiment among the components of the vehicle 101 shown in FIG. 6. The sensor 110 is the same as that in the first embodiment. When the sensor 110 detects an obstacle, it notifies the driving control unit 131 of the detection. While the sensor 110 is detecting an obstacle, it continues to notify the detection signal transmission unit 120 of the detection.

[0041] The traveling control unit 131 operates the traveling of the vehicle 101. The traveling control unit 131 controls the traveling of the vehicle 101 based on an instruction signal transmitted from the information processing device 201. Details of the instruction signal are the same as those in the first embodiment. When the traveling control unit 131 is notified by the sensor 110 that an obstacle has been detected, the traveling control unit 131 prohibits control based on an instruction signal indicating an instruction to make the vehicle 101 travel among the instruction signals. Specifically, for example, when the traveling control unit 131 is notified by the sensor 110 that an obstacle has been detected, the traveling control unit 131 prohibits control based on an instruction signal indicating an instruction to increase the traveling speed of the vehicle 101 among the instruction signals. At this time, the traveling control unit 131 may stop the traveling of the vehicle 101. Also, when the traveling control unit 131 is notified by the sensor 110 that an obstacle has been detected, the traveling control unit 131 prohibits control based on an instruction signal indicating an instruction to maintain the traveling speed of the vehicle ... The notification from the sensor 110 that an obstacle has been detected means that an obstacle has been detected around the vehicle 101. In that case, allowing the vehicle 101 to continue traveling may be dangerous, and therefore the vehicle 101 must not continue traveling. Therefore, when the traveling control unit 131 is notified by the sensor 110 that an obstacle has been detected, the traveling control unit 131 prohibits control based on an instruction signal that is an instruction to travel the vehicle 101, among other instruction signals.

[0042] 7, the vehicle 101 may also be equipped with a camera. This camera captures an image of the field of view from the driver's seat of a typical vehicle, and transmits image data indicating the captured image to the information processing device 201 in real time. The vehicle 101 may also be equipped with a location information acquisition means for acquiring location information indicating the location of the vehicle 101. This location information acquisition means acquires the location information of the vehicle 101 by using, for example, a GPS function. The location information acquisition means transmits the acquired location information to the information processing device 201.

[0043] FIG. 8 is a diagram showing an example of components included in the information processing device 201 shown in FIG. 6. As shown in FIG. 8, the information processing device 201 shown in FIG. 6 has an operation reception unit 210, a database 220, and an instruction signal transmission unit 230. Note that FIG. 8 shows only the main components related to this embodiment among the components included in the information processing device 201 shown in FIG. 6. The operation reception unit 210, the database 220, and the instruction signal transmission unit 230 are the same as those in the first embodiment. The information processing device 201 in this embodiment does not have the transmission control unit 240 provided in the information processing device 200 in the first embodiment.

[0044] Furthermore, when image data is transmitted from the vehicle 101, the information processing device 201 displays the image data on the monitor. Furthermore, when location information is transmitted from the vehicle 101, the information processing device 201 displays a location indicating the location information on the monitor. This monitor may be provided inside the information processing device 201 or may be provided outside the information processing device 201.

[0045] A description will now be given of a remote operation control method in the information processing system shown in Fig. 6. Fig. 9 is a sequence diagram for explaining an example of a remote operation control method in the information processing system shown in Fig. 6.

[0046] When the operation reception unit 210 of the information processing device 201 receives an operation from the outside (step S11), the operation reception unit 210 outputs identification information for identifying the operation (for example, the above-mentioned operation button identification information) to the instruction signal transmission unit 230. The instruction signal transmission unit 230 reads out the instruction content associated with the identification information output from the operation reception unit 210 from the database 220 using the identification information as a search key (step S12). The instruction signal transmission unit 230 transmits an instruction signal indicating the instruction content read out from the database 220 to the vehicle 101 (step S13). The transmission of the instruction signal is continued at a predetermined cycle unless the operation received by the operation reception unit 210 is changed. When the instruction signal is transmitted from the information processing device 201, the traveling control unit 131 of the vehicle 101 controls the traveling of the vehicle 101 according to the instruction content indicated by the transmitted instruction signal (step S14).

[0047] Also, it is determined whether the sensor 110 has detected an obstacle (step S15). This determination process is always performed. When the sensor 110 detects an obstacle, the sensor 110 notifies the driving control unit 131 that an obstacle has been detected. Then, if the instruction signal currently being transmitted from the information processing device 201 at a predetermined period is an instruction signal indicating an instruction to drive the vehicle 101, the driving control unit 131 prohibits control of driving based on the instruction signal (step S16).

[0048] In addition, when the sensor 110 notifies the vehicle that an obstacle has been detected, the driving control unit 131 may not only prohibit the vehicle from controlling driving based on the instruction signal, but may also control the vehicle 101 to stop or slow down.

[0049] Thus, in this embodiment, the information processing device 201 that remotely controls the traveling of the vehicle 101 transmits to the vehicle 101 an instruction signal that controls the traveling of the vehicle 101 based on an operation received from outside, and while the vehicle 101 is traveling according to the instruction signal, if the sensor 110 mounted on the vehicle 101 detects an obstacle around the vehicle 101, the vehicle 101 prohibits the control of traveling based on the instruction signal. This allows the remotely controlled vehicle to travel safely. (Other embodiments)

[0050] The time during which the transmission control unit 240 controls the transmission of the instruction signal from the instruction signal transmission unit 230 in the first embodiment, or the time during which the traveling control unit 131 prohibits the control of traveling based on the instruction signal in the second embodiment may be calculated according to the type of obstacle detected by the sensor 110. In this case, in the first embodiment, the information processing device 200 may have a database in which the type of obstacle and the time during which the transmission control unit 240 controls the transmission of the instruction signal from the instruction signal transmission unit 230 are associated, and the transmission control unit 240 may read the time from the database using the type of obstacle detected by the sensor 110 as a search key, and perform control based on the read time. Also, in the second embodiment, the vehicle 101 may have a database in which the type of obstacle and the time during which the traveling control unit 131 prohibits the control of traveling based on the instruction signal are associated, and the traveling control unit 131 may read the time from the database using the type of obstacle detected by the sensor 110 as a search key, and perform control based on the read time.

[0051] Although the above description has been given by allocating each function (processing) to each component, this allocation is not limited to the above. In addition, the configuration of the components is also not limited to the above-mentioned form, and the above-mentioned form is merely an example. In addition, the above-mentioned embodiments may be combined.

[0052] The processes performed by each of the above-mentioned components may be performed by logic circuits that are created according to the purpose. Also, a computer program (hereinafter referred to as a program) in which the process contents are described as procedures may be recorded on a recording medium that can be read by a device (for example, the vehicles 100, 101, the information processing devices 200, 201, hereinafter referred to as an information processing device) that includes each of the components, and the program recorded on the recording medium may be read and executed by the information processing device. The recording medium that can be read by the information processing device refers to a removable recording medium such as a floppy (registered trademark) disk, a magneto-optical disk, a DVD (Digital Versatile Disc), a CD (Compact Disc), a Blu-ray (registered trademark) Disc, a USB (Universal Serial Bus) memory, and an SD memory card, as well as a memory such as a ROM (Read Only Memory), a RAM (Random Access Memory), and an HDD (Hard Disc Drive) that are built into the information processing device.
