  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, embodiment described below is embodiment when this invention is applied with respect to the information processing apparatus 1 mounted in a motor vehicle (an example of a "mobile body").

[1. First Embodiment]
First, a first embodiment of the present invention will be described.

[1.1. Configuration of information processing apparatus 1]
As illustrated in FIG. 1, the information processing apparatus 1 according to the first embodiment includes a control unit 11, a storage unit 12, a communication unit 13, a display unit 14, a front camera 15 a, a back camera 15 b, an operation unit 16, and a position detection unit 17. And the vehicle information input part 18 is comprised. The control unit 11, the storage unit 12, the communication unit 13, the display unit 14, the front camera 15a, the back camera 15b, the operation unit 16, the position detection unit 17, and the vehicle information input unit 18 are connected via the system bus B. .

  The controller 11 includes a CPU (Central Processing Unit) 11a, a ROM (Read Only Memory) 11b, a RAM (Random Access Memory) 11c, and the like. And the control part 11 as a computer performs various processes etc. by running the program memorize | stored in the memory | storage part 12. FIG. The control unit 11 functions as a detection unit, an OS switching unit, an acquisition unit, a first application control unit, a second application control unit, a first setting unit, a second setting unit, and an image setting unit.

  The storage unit 12 is configured by, for example, a hard disk drive or a non-volatile semiconductor memory, and stores various programs, data, and the like. Specifically, the information processing apparatus 1 stores a program for forming a virtual environment in which a virtual machine (VM) operates, that is, a VMM (Virtual Machine Monitor).

  Further, as shown in FIG. 2, the storage unit 12 includes a first guest OS 41 (an example of “first OS”) and a second guest OS 42 (“ An example of “second OS”) is stored. Furthermore, in the storage unit 12, a first image processing application (hereinafter referred to as “first image processing application”) 51 (an example of “first application”) that operates on the first guest OS 41. ), A second image processing application (hereinafter referred to as “second image processing application”) 52 (an example of “second application”) running on the second guest OS 42 is stored. Yes.

  Further, in the storage unit 12, a device driver (hereinafter referred to as a unit “first guest OS occupation driver”) 21 occupied by the first guest OS 41 and a device driver (hereinafter referred to as “first guest OS occupation driver”) are occupied. , Unit “second guest OS exclusive driver”) 22, device drivers shared by the first guest OS 41 and the second guest OS 42 (hereinafter referred to as unit “shared driver”) 23. It is remembered.

  The VMM 31 is a program that makes it possible to access one or more guest OSs (virtual OSs) by recognizing and controlling hardware such as the CPU 11a and the RAM 11c and abstracting them. When there are a plurality of guest OSes, the access authority to the hardware is appropriately distributed in time division. It should be noted that a device accessed from only one guest OS can be hidden so that it cannot be seen by other guest OSs. The VMM 31 has advantages such that a plurality of guest OSs can be efficiently operated with high-speed hardware, and that the system down of one guest OS does not affect other guest OSs.

  The first guest OS 41 is an OS for operating the first image processing application 51. The second guest OS 42 is an OS for operating the second image processing application 52. The first guest OS 41 is an OS that has higher stability than the second guest OS 42 and can be started at high speed. Specifically, this means that the data amount of the first guest OS 41 itself is smaller than the data amount of the second guest OS 42 itself (description of the program without useless functions to improve stability) Since the amount is small, the data amount of the first guest OS 41 itself is small.) Alternatively, this means that the number registered as applications to be operated on the first guest OS 41 is smaller than the number registered as applications to be operated on the second guest OS 42 (the number of applications operating on the OS). The smaller the number, the lower the possibility that the OS will end abnormally due to the application and the higher the stability.) Alternatively, it means that the probability that the first guest OS 41 needs to be restarted per unit time is lower than that of the second guest OS 42.

  The first guest OS 41 is repeatedly tested to improve the stability. In addition, the program of the first guest OS 41 itself is reduced in size in order to reduce the possibility of occurrence of problems, and the data amount of the program itself is reduced. As will be described later, the first image processing application 51 performs image processing that has a higher priority in terms of safety when driving a car than the second image processing application 52. It operates on one guest OS 41.

  The first image processing application 51 performs image processing having a high priority in terms of safety when driving a car. High priority means that the priority is higher than image processing performed by the second image processing application 52 described later. The image processing performed by the first image processing application 51 and the second image processing application 52 is a process of processing a captured image captured by the front camera 15a and the back camera 15b. The captured image subjected to image processing by the first image processing application 51 or the second image processing application 52 is displayed on the display unit 14. Hereinafter, the image processing performed by the first image processing application 51 is collectively referred to as “first image processing”, and the image processing performed by the second image processing application 52 is collectively referred to as “second image processing”. Good, distinguish between the two.

  As will be described later, the image subjected to the first image processing is displayed on the display unit 14 when the automobile is traveling at a low speed (speed of less than 10 km / h. An example of “first speed range”). Is displayed. Compared to the case where a car is traveling at high speed, there is a high possibility that a contact accident with other objects will occur when the vehicle is traveling at a low speed. It is supposed to be displayed when traveling. On the other hand, the image subjected to the second image processing is displayed on the display unit 14 when the vehicle is traveling at a high speed (speed of 10 km / h or more, an example of “second speed range”). .

  The first image processing performed by the first image processing application 51 includes, for example, (i) processing for correcting distortion of a captured image, (ii) processing for enhancing a moving object in the captured image, and (iii) shooting This is a process of drawing a parking auxiliary line on an image. (i) The process of correcting the distortion of the captured image is a process of correcting the distortion included in the captured image captured by the front camera 15a and the back camera 15b. As a result of this processing, a photographic image without distortion is displayed on the display unit 14, so that the user (automobile operator) can visually recognize the photographic image without a sense of incongruity, and safety during low-speed driving is improved. Further, (ii) the process of emphasizing moving objects in a captured image is a moving object (for example, a person, an animal, a car, a bicycle, etc.) in a captured image captured by the front camera 15a and the back camera 15b. Is detected, and the object is emphasized by drawing a line surrounding the object. As a result of this processing, a captured image in which a moving object is highlighted is displayed on the display unit 14, so that the user can easily recognize the presence of an object moving around the automobile and travel at low speed. Safety at the time is improved. Further, (iii) the process of drawing the parking auxiliary line on the photographed image refers to the direction in which the vehicle body is directed according to the steering wheel operation in the photographed image photographed by the back camera 15b when the automobile moves backward (back). This is a process of drawing the auxiliary line for parking shown. As a result of this processing, a captured image on which a parking auxiliary line is drawn is displayed on the display unit 14 when the vehicle moves backward (back), so that the user can easily grasp the direction sense while moving backward (back). The direction in which the vehicle heads can be easily grasped, and safety during reverse (back) is improved. It can be set to perform all the processes (i) to (iii), or can be set to perform some of these processes. This setting may be set in advance when the information processing apparatus 1 is sold, or the user may be able to set the information processing apparatus 1 after purchase. At this time, the control unit 11 (an example of “first setting unit”) performs at least one of the processes (i) to (iii) based on an instruction from the user by the first image processing application 51. This is set as the first image processing. The image that has been subjected to the set image processing is an example of “an image to be displayed when moving in the first speed range”.

  The second image processing performed by the second image processing application 52 includes, for example, (a) a process for emphasizing a sign in a captured image, and (b) a process for measuring a distance between the own vehicle and another vehicle. is there. (a) The process of emphasizing the sign in the photographed image is to detect a sign such as a sign in the photographed image photographed by the front camera 15a while the vehicle is running, and to draw a line surrounding the sign. This process emphasizes the sign. As a result of this processing, the captured image on which the sign is highlighted is displayed on the display unit 14, so that the user can easily recognize the presence of the sign. (b) The process of measuring the inter-vehicle distance between the host vehicle and the other vehicle is a process of measuring the inter-vehicle distance between the host vehicle and the other vehicle traveling ahead. When the measured inter-vehicle distance is shorter than a predetermined threshold (that is, when the host vehicle and another vehicle approach each other), for example, warning information such as “too close to the vehicle ahead” is drawn on the photographed image. It is good to do. In this case, since the captured image on which the warning information is drawn is displayed on the display unit 14, the user can recognize that the own vehicle is approaching another vehicle traveling ahead, and safety. Improves. Note that it can be set to perform the processes (a) and (b), or can be set to perform either one of the processes. This setting may be set in advance when the information processing apparatus 1 is sold, or the user may be able to set the information processing apparatus 1 after purchase. At this time, the control unit 11 (an example of “second setting means”) performs at least one of the processes (a) and (b) based on an instruction from the user by the second image processing application 52. This is set as the second image processing. The image that has been subjected to the set image processing is an example of “an image to be displayed when moving in the second speed range”.

  It should be noted that the image to be displayed when the car is moving at a low speed (speed of less than 10 km / h; an example of “first speed range”) and the car is at a high speed (speed of 10 km / h or higher. In the example of “2 speed range”, the user may be able to set what kind of image processing each image to be displayed is to be displayed when moving. At this time, the control unit 11 (an example of “image setting means”) displays an image to be displayed when the automobile is moving at a low speed or an automobile is moving at a high speed based on an instruction from the user. At this time, an image to be displayed is set.

  In addition to the above-described programs, the storage unit 12 stores applications for realizing various functions and a guest OS for operating these applications. The information processing apparatus 1 may, for example, capture various programs from other server apparatuses or the like via a network and record them in the storage unit 12, or may record various programs recorded on a recording medium such as a DVD-ROM. May be read by the optical drive and recorded in the storage unit 12.

  The communication unit 13 performs processing related to communication between the information processing device 1 and other server devices, terminal devices, and the like via a network. The network is constructed by, for example, the Internet, a dedicated communication line (for example, a CATV (Community Antenna Television) line), a mobile communication network (including a base station, etc.), a gateway, and the like.

  The display unit 14 (an example of “display unit”) is configured by, for example, a liquid crystal display. The display unit 14 displays a captured image that has been subjected to image processing by the first image processing application 51 or the second image processing application 52.

  The front camera 15a is a camera that photographs the front of the automobile as viewed from the automobile side. The back camera 15b is a camera that captures the back of the automobile as viewed from the automobile side. The captured images captured by the front camera 15a and the back camera 15b are sent to the control unit 11, and image processing is performed by the first image processing application 51 and the second image processing application 52. Here, the operator of the car can select the travel range by the select lever. The travel range is roughly divided into a stop range (for example, “P (Parking) range”, “N (Neutral) range”), a forward range (for example, “D (Drive) range”, “2 (second) range”), “ L (Low) range ") and reverse range (for example," R (Reverse) range "). In the present embodiment, when the reverse range is selected, the control unit 11 displays the captured image captured by the back camera 15b on the display unit 14, while the forward range is selected. If there is, the captured image is displayed on the display unit 14 captured by the front camera 15a. The control unit 11 is configured not to display the captured image on the display unit 14 when the stop range is selected.

  The operation unit 16 includes, for example, a touch panel, buttons, and the like. The operation unit 16 receives an operation instruction from a user and outputs the instruction content to the control unit 11 as an instruction signal.

  The position detection unit 17 includes a GPS (Global Positioning System) reception unit, a speed sensor, an azimuth angle sensor, a gyroscope, and the like. The position detection unit 17 detects the current position of the information processing apparatus 1 and controls a signal indicating the current position. 11 is output.

  The vehicle information input unit 18 acquires various vehicle information from the automobile body and outputs the vehicle information to the control unit 11 as a signal indicating the vehicle information. The vehicle information includes information indicating the speed of the automobile (vehicle speed), information indicating the travel range selected by the select lever, information indicating whether the headlight is lit, and whether the wiper is operating. Information indicating whether the blinker is lit, information indicating whether the hazard is lit, information related to ITS (Intelligent Transport Systems), and the like. Based on the information indicating the vehicle speed and the information indicating the travel range selected by the select lever, the control unit 11 determines whether the moving state of the vehicle is a stopped moving state (“vehicle speed = 0 km / h”) or a low-speed moving state. (“0 km / h <vehicle speed <10 km / h”) or high-speed movement state (“vehicle speed ≧ 10 km / h”).

  As described above, when the automobile is traveling at a high speed (that is, a speed of 10 km / h or more, an example of the “second speed range”), the image subjected to the second image processing is displayed on the display unit 14. When the vehicle speed is reduced and the vehicle is traveling at a low speed (that is, a speed of less than 10 km / h; an example of “first speed range”), an image subjected to the first image processing is displayed on the display unit 14. Is displayed. Although not shown, the control unit 11 stops the first image processing when the vehicle speed further decreases, the vehicle stops, and the stop range is selected by the select lever.

  In FIG. 5, the processing in the case of shifting from high speed traveling to low speed traveling and stopping has been described, but the processing in the case of shifting from high speed traveling to low speed traveling and again to high speed traveling is illustrated in FIG. 4 and FIG. 5 is a combination process. Specifically, the processing when shifting from high speed traveling to low speed traveling is as shown in FIG. 5, and when shifting to high speed traveling again, the processing after step S102 in FIG. 4 is performed.

  As described above, in the information processing apparatus 1 according to the first embodiment, the control unit 11 detects the moving state of the automobile (an example of “moving body”) and operates in the virtual environment. (An example of “first OS”) and a second guest OS 42 (“second OS”) that operates in a virtual environment and has a larger data amount than the first guest OS 41. The display unit 14 (an example of “predetermined device”). ) Is switched according to the detected movement state of the automobile.

  Therefore, in the information processing apparatus 1 according to the first embodiment, in a moving state with a high degree of risk (accident occurrence rate) (for example, a moving state in which the vehicle is traveling at a low speed), a first process of reducing the degree of risk is executed. The image processing application 51 is operated on the first guest OS 41 having higher stability, and the use authority of the display unit 14 used in the first image processing application 51 is given to the first guest OS 41. It is possible to improve safety in a moving state with a high degree of danger (incidence rate of accidents).

  In the information processing apparatus 1 according to the first embodiment, the control unit 11 acquires a captured image obtained by capturing the periphery of the automobile from the front camera 15a and the back camera 15b, and performs first image processing on the captured image. A first image processing application 51 that generates an image to be displayed when the vehicle is traveling at a low speed (speed of less than 10 km / h; an example of “first speed range”) and displays the image on the display unit 14. (An example of “first application”) is operated on the first guest OS 41. In addition, the control unit 11 performs second image processing on the captured image, and displays the image when the automobile is traveling at a high speed (speed of 10 km / h or more; an example of “second speed range”). A second image processing application 52 (“second application”) that generates a power image and displays it on the display unit 14 is operated on the second guest OS 42. Further, the control unit 11 gives the authority to display an image on the display unit 14 to the first guest OS 41 when the moving state in which the vehicle is traveling at a low speed is detected, and the vehicle travels at a high speed. When the moving state is detected, the second guest OS 42 is given authority to display an image on the display unit 14.

  Therefore, according to the information processing apparatus 1 in the first embodiment, when the moving state of the vehicle is a low-speed traveling state with a high degree of danger (accident occurrence rate), the first guest OS 41 with higher stability is used. Since the image to be displayed when the vehicle is traveling at a low speed, which is subjected to the first image processing by the first image processing application 51 operating in the above, is displayed on the display unit 14, Safety can be improved. In addition, since the second image processing application 52 that performs the second image processing with low priority in terms of safety is not operated on the first guest OS 41 but is operated on the second guest OS 42, Even if a problem occurs in the image processing application 52, the first guest OS 41 and the first image processing application 51 are not adversely affected, and the image subjected to the first image processing is reliably displayed during low-speed traveling. be able to.

  In the first embodiment, as shown on the left side of FIG. 4, the control unit 11 determines whether or not the vehicle speed is 10 km / h or more (step S102), and when the vehicle speed is 10 km / h or more (step S102). : Yes), the second guest OS 42 side is requested to start the second image processing (step S103), but instead of this, not only the control unit 11 that executes the first guest OS 41, When the control unit 11 that executes the second guest OS 42 determines whether the vehicle speed is 10 km / h or more as a determination of whether the vehicle speed is 10 km / h or more, the controller 11 starts the second image processing by itself. It is good also as composition to do. Similarly, when the vehicle shown in FIG. 5 is decelerated, the control unit 11 that executes the second guest OS 42 determines whether or not the vehicle speed is less than 10 km / h. A configuration may be adopted in which the second image processing is stopped by itself when it is determined that the number is less than the predetermined value. 4 and 5, the first guest OS 41 side makes a determination (determination of whether or not the vehicle speed is 10 km / h or more) when switching the OS having the authority to use the display unit 14. However, instead of this, the second guest OS 42 may perform, and the first guest OS 41 may be requested to start or stop the first image processing according to the determination result. .

  In the first embodiment, the first image processing application 51 is configured to perform the first image processing on the captured images captured by the front camera 15a and the back camera 15b and display the images on the display unit 14. However, in addition to or instead of this, the first image processing application 51 does not perform the first image processing on the photographed images photographed by the front camera 15a and the back camera 15b, and displays the display unit 14 as it is. It is good also as a structure displayed on.

[2. Second Embodiment]
Next, a second embodiment of the present invention will be described. In the first embodiment described above, the display unit 14 is used by the first guest OS 41 and the second guest OS 42 depending on whether the moving state of the vehicle is a low-speed driving state or a high-speed driving state. In the second embodiment described below, the authorized OS is switched, but in the second embodiment described below, a predetermined distance from the toll booth where the automobile pays the toll is set (100 m in this embodiment. Other distance is appropriately set as appropriate). Or within a predetermined distance (100 m in this embodiment. It may be set to other distances as appropriate) from the checkout office where the car pays for a fee other than the toll. The OS having the authority to use the ETC (Electronic Toll Collection System) vehicle-mounted device (an example of “wireless communication device”) is switched between the first guest OS 41 and the second guest OS 42 according to .

  Since the information processing apparatus 1A in the second embodiment has substantially the same configuration as the information processing apparatus 1 in the first embodiment, the same reference numerals are used for the same members and processes, and a part of the description is omitted. The explanation will be focused on.

[2.1. Configuration of Information Processing Apparatus 1A]
As shown in FIG. 6, the information processing apparatus 1A according to the second embodiment includes a control unit 11, a storage unit 12, a communication unit 13, a display unit 14, a front camera 15a, a back camera 15b, an operation unit 16, and a position detection unit 17. The vehicle information input unit 18 and the ETC vehicle-mounted device 19 are included. The control unit 11, the storage unit 12, the communication unit 13, the display unit 14, the front camera 15a, the back camera 15b, the operation unit 16, the position detection unit 17, the vehicle information input unit 18, and the ETC onboard device are connected via the system bus B. It is connected.

  As shown in FIG. 7, the storage unit 12 includes a first ETC application (hereinafter referred to as “first ETC application”) 53 (“first settlement application”) that operates on the first guest OS 41. ), And a second ETC application (hereinafter referred to as “second ETC application”) 54 (an example of “second settlement application”) running on the second guest OS 42. It is remembered.

  The first guest OS 41 is an OS for operating the first ETC application 53. The second guest OS 42 is an OS for operating the second ETC application 54.

  The first ETC application 53 is an application for paying the toll using the ETC on-vehicle device 19 at a toll gate provided at the entrance of a toll road, for example. In the vicinity of the toll booth, there is a high probability of an accident because the car will once slow down and accelerate again. In addition to this, if the first ETC application 53 malfunctions near the toll booth and the toll fee is not normally settled, the risk increases. Therefore, the first ETC application 53 that performs the checkout process near the toll gate is set to operate on the first guest OS 41 with higher stability.

  The second ETC application 54 is an application for paying the product price using the ETC in-vehicle device 19 at a checkout place provided in a drive-through passage, for example. In general, there is a lower probability of an accident near the checkout station than near the toll booth, and even if a failure occurs in the second ETC application 54 near the checkout station, there is a low possibility of being directly connected to the accident. The second ETC application 54 is set to operate on the second guest OS 42 that is less stable than the first guest OS 41.

  The storage unit 12 (an example of “storage means”) stores location information indicating the locations of the toll gate and the checkout office. Based on the location information and the signal indicating the current position received from the position detection unit 17 (an example of “current position acquisition unit”) (an example of “current position information”), the control unit 11 It is detected that the vehicle exists within a predetermined distance or that the automobile exists within a predetermined distance from the checkout office.

  The ETC vehicle-mounted device 19 performs wireless communication with wireless devices installed at the toll gate and the checkout station, and exchanges information for adjusting tolls and product charges.

[2.2. Operation of information processing apparatus 1A]
Next, an outline of the operation of the information processing apparatus 1A will be described with reference to FIGS. 8 and 9, the operation outline will be described separately for the VMM 31, the first guest OS 41, and the second guest OS 42. FIG. 8 illustrates the operation of the information processing apparatus 1 </ b> A when the automobile enters an area within 100 m from the checkout office. In FIG. 9, operation | movement of 1 A of information processing apparatuses when a motor vehicle leaves the area within 100 m from a checkout station is demonstrated.

  The processing shown in FIG. 8 is a state in which the automobile is not present in an area within 100 m from the checkout station, and the authority to use the ETC on-vehicle device 19 is given to the first guest OS 41 by the VMM 31. Begins. Further, it is assumed that the first ETC application 53 is activated and the second ETC application 54 is stopped. Note that the processing from step S151 to step S154 shown on the left side of FIG. 8 is performed by the control unit 11 executing the first guest OS 41 or the first ETC application 53. The process of step S251 and the process of step S252 shown in the center of FIG. 8 are performed by the control unit 11 executing the second guest OS 42 or the second ETC application 54. The process of step S351 and the process of step S352 illustrated on the right side of FIG. 8 are performed by the control unit 11 executing the VMM 31.

  First, as shown on the left side of FIG. 8, the control unit 11 determines whether or not the automobile has entered an area within 100 m from the checkout station (step S151). The control unit 11 waits until the vehicle enters an area within 100 m from the checkout (step S151: NO), and determines that the vehicle has entered an area within 100m from the checkout (step S151: YES), An activation request for the second ETC application 54 is made to the second guest OS 42 (step S152).

  On the other hand, as shown in the center of FIG. 8, when the control unit 11 receives an activation request for the second ETC application 54 from the first guest OS 41, the control unit 11 activates the second ETC application 54 (step S251). Then, the activation completion report of the second ETC application 54 is sent to the first guest OS 41 (step S252).

  As shown on the left side of FIG. 8, when the control unit 11 receives the activation completion report of the second ETC application 54 from the second guest OS 42, it makes an OS switching request to the VMM 31 (step S153).

  On the other hand, as shown on the right side of FIG. 8, when the control unit 11 receives an OS switching request from the first guest OS 41, the control unit 11 switches the OS (step S351). Specifically, the control unit 11 transfers the authority to use the ETC vehicle-mounted device 19 from the first guest OS 41 to the second guest OS 42. As a result, the product price is settled by the processing of the second ETC application 54 at the settlement office. When the process of step S351 is completed, the control unit 11 sends an OS switching completion report to the first guest OS 41 (step S352).

  As shown on the left side of FIG. 8, when the control unit 11 receives the OS switching completion report from the VMM 31, the control unit 11 stops the first ETC application 54 (step S154).

  Thus, when the car does not exist in an area within 100 m from the checkout office (including the case where the car exists in an area within 100 m from the toll gate), the first ETC application 53 is activated and the second The ETC application 54 is stopped. On the other hand, when the vehicle is in an area within 100 m from the checkout office, the second ETC application 54 is activated and the first ETC application 53 is stopped.

  Next, the operation of the information processing apparatus 1A when the automobile leaves an area within 100 m from the checkout office will be described with reference to FIG.

  The process shown in FIG. 9 is in a state where the automobile exists in an area within 100 m from the checkout station, and from the time when the authority to use the ETC vehicle-mounted device 19 is given to the second guest OS 42 by the VMM 31. Begins. In addition, it is assumed that the second ETC application 54 is activated and the first ETC application 53 is stopped. Note that the processing from step S171 to step S173 shown on the left side of FIG. 9 is performed by the control unit 11 executing the first guest OS 41 or the first ETC application 53. The processing from step S271 to step S273 shown in the center of FIG. 9 is performed by the control unit 11 executing the second guest OS 42 or the second ETC application 54. The process of step S371 and the process of step S372 illustrated on the right side of FIG. 9 are performed by the control unit 11 executing the VMM 31.

  First, as shown in the center of FIG. 9, the control unit 11 determines whether or not the automobile exists in an area within 100 m from the checkout station (step S271). The control unit 11 waits until the car no longer exists in the area within 100 m from the checkout (that is, until the car leaves the area within 100 m from the checkout) (step S271: YES), and the car is 100 m from the checkout. The first ETC application 53 is activated for the first guest OS 41 when the vehicle no longer exists in the area (that is, the car has left the area within 100 m from the checkout station) (step S271: NO). A request is made (step S272).

As shown on the left side of FIG. 9, when receiving the activation request for the first ETC application 53 from the second guest OS 42, the control unit 11 activates the first ETC application 53 (step S <b> 171), and An OS switching request is made (step S172).

  On the other hand, as shown on the right side of FIG. 9, when the control unit 11 receives an OS switching request from the first guest OS 41, the control unit 11 switches the OS (step S371). Specifically, the control unit 11 transfers the authority to use the ETC vehicle-mounted device 19 from the second guest OS 42 to the first guest OS 41. When the processing of step S371 is completed, the control unit 11 sends an OS switching completion report to the first guest OS 41 (step S372).

  As illustrated on the left side of FIG. 9, when the control unit 11 receives the OS switching completion report from the VMM 31, the control unit 11 requests the second guest OS 42 to stop the second ETC application 54 (step S173).

  As shown in the center of FIG. 9, when receiving a stop request for the second ETC application 54 from the first guest OS 41, the control unit 11 stops the second ETC application 54 (step S273).

  9 is completed, the initial state of the process shown in FIG. 8 is the same.

  As described above, in the information processing apparatus 1 </ b> A according to the second embodiment, the control unit 11 detects the movement state of the automobile (an example of “moving body”) and operates in the virtual environment. (An example of “first OS”) and a second guest OS 42 (“second OS”) that operates in a virtual environment and has a larger data amount than the first guest OS 41. ETC on-vehicle device 19 (an example of “predetermined device”). ) Is switched according to the detected movement state of the automobile.

  Therefore, in the information processing apparatus 1A according to the second embodiment, in a moving state with a high degree of risk (accident occurrence rate) (for example, a moving state traveling within 100 m from a toll gate), processing corresponding to the moving state is performed. The first ETC application 53 for executing the ETC is operated on the first guest OS 41 with higher stability, and the use authority of the ETC on-vehicle device 19 used in the first ETC application 53 is granted to the first guest OS 41 By doing so, it is possible to improve the safety in a moving state with a high degree of danger (accident occurrence rate).

  In the information processing apparatus 1 </ b> A according to the second embodiment, the control unit 11 uses the ETC vehicle-mounted device 19 (an example of “wireless communication device”) to perform a toll fee settlement process at a toll gate. The ETC application 53 (an example of “first settlement application”) is operated on the first guest OS 41. Further, the control unit 11 uses a second ETC application 54 (an example of a “second settlement application”) that performs a settlement process for charges other than the toll at the checkout station using the ETC on-vehicle device 19. It runs on the guest OS 42. Furthermore, the control unit 11 uses the ETC on-vehicle device 19 for the first guest OS 41 when detecting a moving state in which the vehicle moves within 100 m (an example of “predetermined distance”) from the toll gate. If the authority is given and a movement state in which the car moves within 100 m (an example of “predetermined distance”) from the checkout office is detected, the authority to use the ETC on-vehicle device 19 is given to the second guest OS 42. Give.

  Therefore, according to the information processing apparatus 1A in the second embodiment, when the moving state of the vehicle is a moving state that is moving within 100 m from a toll gate having a high degree of risk (accident occurrence rate), it is more stable. Since the first ETC application 53 operating on the first guest OS 41 having a high degree performs settlement processing using the ETC on-board unit 19 at the toll gate, safety within 100 m from the toll gate can be improved. it can. In addition, since the second ETC application 54 that performs the settlement process using the ETC on-board unit 19 at the settlement office is not operated on the first guest OS 41 but is operated on the second guest OS 42, the second ETC application 54 is operated. Even if a failure occurs in the application 54, the first guest OS 41 and the first ETC application 53 are not adversely affected, and the checkout process at the toll gate can be reliably performed.

  In addition, based on the communication content acquired from the ETC vehicle-mounted device 19 in which the control unit 11 wirelessly communicates with the wireless devices installed at the toll gate and the checkout office, the vehicle exists within a predetermined distance from the toll gate, or It is good also as a structure which detects that a motor vehicle exists in a predetermined distance from a checkout office.
