(Embodiment 1)
In the present embodiment, a driving support system 1 including a driving support device 11 and a server device 12 will be described. The travel support device 11 receives the traffic situation information from the server device 12, and supports the travel of the low-speed moving body according to the traffic situation indicated by the traffic situation information. Further, the server device 12 holds traffic situation information and transmits the traffic situation information to the travel support device 11.

  FIG. 1 is a conceptual diagram of a driving support system 1 in the present embodiment. In FIG. 1, the driving support device 11 and the server device 12 are connected via a communication means 13. The driving support device 11 is usually mounted on a low-speed moving body. A “low speed moving body” is a moving body that travels at a relatively low speed. “Running at a relatively low speed” specifically means that the maximum speed is slow enough to satisfy a predetermined condition. In addition, the “low speed moving body” is a moving body that can physically travel on the sidewalk regardless of whether it is legal or illegal, and may be any moving body on which a person can ride. “Low-speed moving bodies” include, for example, Segway (registered trademark), standing riding scooters, electric assist bicycles, electric wheelchairs (senior cars), walking assist devices (for example, “http://www.honda.co.jp/robotics / weight / "). The communication unit 13 is usually a wireless communication unit, but may be a wired communication unit. The communication means 13 is, for example, a wireless LAN or the Internet.

  FIG. 2 is a block diagram of the travel support device 11 and the server device 12 in the present embodiment. The travel support device 11 includes a reception unit 111, a current position information acquisition unit 112, a reception unit 113, a determination unit 114, and a travel support unit 115. The server device 12 includes a server traffic condition information storage unit 121 and a server transmission unit 122.

  The receiving unit 111 receives traffic state information from the server device 12. “Traffic situation information” is information relating to the traffic situation. The “traffic situation” is, for example, an accident occurrence situation, a passerby situation, or the like. “Accident occurrence status” refers to whether or not a current accident has occurred, whether or not an accident has occurred in the past, and whether or not an accident is likely to occur. The “passerby status” includes the presence or absence of a passerby and the number of passersby.

  Further, “traffic condition information” is usually information having one or more pieces of position information. “Position information” is information indicating a position. The “position” is usually longitude and latitude. The “position” may be coordinates on a map, for example. The “position” may include, for example, altitude (height). Moreover, the area (area | region, area, area, etc.) on a map is shown by the said 1 or more position information. The area on the map is an area subject to traffic conditions. The area on the map is also an area for assisting the traveling of the low-speed moving body. Therefore, the area on the map is hereinafter referred to as a travel support area as appropriate. In addition, the shape of a driving assistance area is not ask | required.

  Further, the “traffic situation information” may include, for example, traffic situation content information. The “traffic situation content information” is information indicating the contents of the traffic situation. “The contents of the traffic situation” means, for example, that a traffic accident has occurred, that it is a frequent traffic accident area, that there are passers-by, and that there are 10 to 20 passers-by.

  In addition, the receiving unit 111 is usually realized by a wireless or wired communication unit, but may be realized by a unit that receives a broadcast.

  The current position information acquisition unit 112 acquires current position information that is information indicating the current position. “Current position information” is position information indicating the current position. Further, the current position information acquisition unit 112 normally acquires current position information periodically. The current position information acquisition unit 112 normally acquires current position information from a satellite navigation system (such as a GPS receiver) or a device that receives position information from a base station for mobile communication. In this case, the current position information acquisition unit 112 may have these devices or may be realized by these devices. The processing procedure of the current position information acquisition unit 112 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The accepting unit 113 accepts an instruction. The instructions include, for example, an acceleration instruction that is an acceleration instruction, a deceleration instruction that is a deceleration instruction, a power-on instruction, and a power-off instruction. Note that when these instructions are received, the driving support device 11 performs control of a low-speed moving body or predetermined processing in accordance with these instructions.

  The acceptance includes, for example, acquisition of information according to an operation of a handle, an accelerator lever, a power switch, etc., acquisition of information stored in a recording medium such as an optical disk, a magnetic disk, or a semiconductor memory. It is.

  Moreover, the reception part 113 receives said instruction | indication from a user normally through operation, such as a handle | steering-wheel, an accelerator lever, and a power switch. In this case, for example, the reception unit 113 may include these devices, or may be realized by these devices. The processing procedure of the reception unit 113 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The determination unit 114 determines whether to assist driving of the low-speed moving body. “Support for traveling of a low-speed moving body” is hereinafter referred to as travel support as appropriate. The determination unit 114 normally holds in advance conditions for determining whether or not to perform driving support (hereinafter referred to as driving support determination conditions as appropriate). Then, the determination unit 114 determines whether to perform driving support using the driving support determination condition. Specifically, the determination unit 114 determines whether the determination target based on the driving support determination condition satisfies the driving support determination condition. Then, the determination unit 114 determines that the driving support is performed when the target of the determination based on the driving support determination condition satisfies the driving support determination condition.

  In the present embodiment, the “running support determination condition” is usually a condition related to the current position. Specifically, the “condition relating to the current position” is a condition relating to the relationship between the current position indicated by the current position information and the position indicated by one or more pieces of position information included in the traffic situation information received by the reception unit 111. In other words, the “condition regarding the current position” is a condition regarding the positional relationship between the current position and the travel support area. The “condition regarding the current position” is, for example, that the current position is a position in the driving support area, or that the current position is a position around the driving support area. The “periphery” means that the distance from the boundary of the driving support area is close enough to satisfy a predetermined condition. The “distance” is usually a spatial distance, but may be a temporal distance.

  For example, the determination unit 114 uses the current position information and one or more pieces of traffic situation information to determine which driving support area the current position indicated by the current position information is, and whether the current position information is It is determined whether or not the current position shown is a position around any driving support area. The range of the driving support area is indicated by one or more pieces of position information included in the traffic situation information. Then, the determination unit 114 determines whether the current position is a driving support when the current position is a position within any driving support area or when the current position is a position around any driving support area. Judge that the condition is met. Then, the determination unit 114 determines to perform driving support.

  For example, the determination unit 114 performs the above determination every time the current position information acquisition unit 112 acquires current position information.

  In addition, the determination unit 114 can usually be realized by an MPU, a memory, or the like. The processing procedure of the determination unit 114 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. Note that the determination unit 114 and the like may be realized by hardware (a dedicated circuit).

  The travel support unit 115 performs travel support when the determination unit 114 determines to perform travel support. “Running support” means, for example, controlling the running of a low-speed moving body or performing a predetermined output.

  The above-mentioned “control of traveling of a low-speed moving body” specifically includes speed control, acceleration control, and the like. “Speed control” is usually to suppress the speed so that the speed does not exceed a predetermined threshold. In addition, “acceleration control” is usually to suppress the acceleration so that the acceleration does not exceed a predetermined threshold. Further, the “predetermined threshold value” is normally held in advance by the driving support unit 115. “Over” includes “excess”.

  In addition, the “predetermined output” is usually for alerting that the current position is in the driving support area or that the current position is in the vicinity of the driving support area. In addition, “predetermined output” specifically means screen output, sound output, output of a signal for vibrating a low-speed moving body, transmission to an external device, accumulation in a recording medium, etc. This is a concept including delivery of processing results to other processing devices and other programs. In addition, regarding transmission, accumulation, and delivery of processing results, an output target is finally presented to the user.

  As described above, the “running assistance” is usually assistance that is performed so that the user can safely travel with the low-speed moving body (so that the low-speed moving body can travel safely).

  For example, the driving support unit 115 may hold in advance conditions for determining what kind of driving support to perform (hereinafter, referred to as driving support execution conditions as appropriate). In this case, the travel support unit 115 performs travel support using the travel support execution condition. Specifically, the driving support unit 115 determines whether the determination target based on the driving support execution condition satisfies the driving support execution condition. The driving support unit 115 performs driving support when the target of the determination based on the driving support execution condition satisfies the driving support execution condition.

  The “running support execution condition” is, for example, a condition related to speed or a condition related to acceleration. The “condition regarding speed” is, for example, that the speed is equal to or higher than a predetermined threshold, or that the speed exceeds a predetermined threshold. In addition, the “condition regarding acceleration” means that the acceleration is equal to or higher than a predetermined threshold, or that the acceleration exceeds a predetermined threshold. The “more than” may be “less than”. The “excess” may be “less than”.

  For example, when the “running support execution condition” is a condition related to speed, the running support unit 115 acquires the speed of the low-speed moving body. Then, the driving support unit 115 determines whether or not the speed satisfies a driving support execution condition. If the speed satisfies the driving support execution condition, the driving support unit 115 controls the speed so that the speed does not satisfy the driving support execution condition.

  For example, when the “running support execution condition” is a condition related to acceleration, the running support unit 115 acquires the acceleration of the low-speed moving body. Then, the driving support unit 115 determines whether or not the acceleration satisfies a driving support execution condition. When the acceleration satisfies the driving support execution condition, the driving support unit 115 controls the acceleration so that the speed does not satisfy the driving support execution condition.

  Further, the driving support unit 115 may perform a predetermined output when, for example, the speed or acceleration of the low-speed moving body satisfies the driving support execution condition regarding the speed or acceleration.

  In addition, the travel support unit 115 may perform travel support when, for example, the speed or acceleration of the low-speed moving body does not satisfy the travel support execution condition related to speed, acceleration, or the like. That is, in this case, for example, when the driving support execution condition is a condition regarding speed, the driving support unit 115 causes the speed to satisfy the driving support execution condition when the speed of the low-speed moving body does not satisfy the driving support execution condition. In addition, the speed is controlled. For example, when the driving support execution condition is a condition related to acceleration, the driving support unit 115 determines that the acceleration satisfies the driving support execution condition when the acceleration of the low-speed moving body does not satisfy the driving support execution condition. Control. For example, the driving support unit 115 performs a predetermined output when the speed, acceleration, or the like of the low-speed moving body does not satisfy the driving support execution condition related to speed, acceleration, or the like.

  Further, the “condition regarding acceleration” may be, for example, an instruction for acceleration that is so rapid that the acceleration instruction received by the reception unit 113 satisfies a predetermined condition. In other words, the condition is that the accepting unit 113 accepts an acceleration instruction that is an instruction of acceleration that is sudden enough to satisfy a predetermined condition. In this case, the driving support unit 115 determines whether the acceleration instruction received by the receiving unit 113 satisfies the driving support execution condition (whether the receiving unit 113 receives an acceleration instruction that satisfies the driving support execution condition). To do. When the acceleration instruction satisfies the driving support execution condition (when the receiving unit 113 receives an acceleration instruction that satisfies the driving support execution condition), the driving support unit 115 controls the acceleration.

  Further, when the low-speed moving body is a power-assisted bicycle, the travel support unit 115 controls the degree of assist to the user by the power-assisted bicycle when the determination unit 114 determines that the low-speed moving body is supported. I do. “Control of the degree of assist” means, for example, that the assist is loosened so that the acceleration does not exceed a predetermined threshold, or the assist is loosened so that the speed does not exceed a predetermined threshold. .

  When the low-speed moving body is a walking assistance device, the driving support unit 115 controls the degree of assistance to the user by the walking auxiliary device when the determination unit 114 determines that the low-speed moving body is supported. I do. “Control of the degree of assistance” means, for example, that the assistance is loosened so that the acceleration does not exceed a predetermined threshold, or the assistance is loosened so that the speed does not exceed a predetermined threshold. is there.

  The driving support unit 115 can be usually realized by an MPU, a memory, or the like. In addition, the processing procedure of the driving support unit 115 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. The driving support unit 115 and the like may be realized by hardware (dedicated circuit).

  In addition, the driving support unit 115 may be considered to include an output device such as a display or a speaker, or may not be included. In this case, the driving support unit 115 can be realized by driver software of an output device or driver software and an output device of an output device.

  One or more traffic condition information is stored in the server traffic condition information storage unit 121 constituting the server device 12. The server traffic situation information storage unit 121 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium. Moreover, the process in which predetermined information is memorize | stored in the server traffic condition information storage part 121 grade | etc., Is not ask | required. For example, the predetermined information may be stored in the server traffic condition information storage unit 121 or the like via a recording medium, a communication line, an input device, or the like.

  The server transmission unit 122 transmits one or more traffic situation information stored in the server traffic situation information storage unit 121 to the driving support device 11. At this time, the server transmission part 122 transmits all the traffic condition information stored in the server traffic condition information storage part 121, for example.

  Moreover, the server transmission part 122 may transmit only the traffic condition information which satisfy | fills a predetermined condition among the 1 or more traffic condition information stored in the server traffic condition information storage part 121, for example. The predetermined condition is usually a condition related to a distance between the current position of the low-speed moving body (travel support apparatus 11) and the travel support area indicated by one or more position information included in the traffic condition information. That is, the server transmission unit 122 acquires one or more traffic condition information from the server traffic condition information storage unit 121 that are close enough to satisfy the predetermined distance between the current position and the travel support area. Then, the server transmission unit 122 transmits the acquired one or more pieces of traffic condition information to the travel support device 11.

  The acquisition of the one or more traffic condition information may be performed by a server traffic condition information acquisition unit (not shown), for example. In this case, the server transmission unit 122 transmits one or more traffic situation information acquired by the server traffic situation information acquisition unit to the travel support device 11.

  In addition, the server transmission unit 122 is usually realized by a wireless or wired communication unit, but may be realized by a broadcasting unit.

  In the flowchart of FIG. 5, the process may be terminated by turning off the power or by interrupting the process.

(Concrete example)
Next, a specific example of the operation of the driving support system 1 will be described. In this specific example, the low speed moving body is an electric wheelchair. Moreover, the driving assistance apparatus 11 shall be a control apparatus of an electric wheelchair. In addition, the current position information acquisition unit 112 included in the driving support device 11 periodically acquires the current position information from when the electric wheelchair is turned on until the power is turned off. Further, it is assumed that the traffic status information shown in FIG. 6 is stored in the server traffic status information storage unit 121. The traffic situation information includes an ID for uniquely identifying a record, one or more pieces of position information (item name: travel support area), and traffic situation content information (item name: content). The driving support area is indicated by the one or more pieces of position information. Further, the driving support determination condition is that the current position is within the driving support area.

(Example 1)
In this example, an example in which acceleration is controlled in the driving support area will be described.

  First, it is assumed that the user gets on the electric wheelchair, turns on the electric wheelchair, and starts running. Then, a transmission unit (not shown) transmits a traffic condition information transmission instruction, which is an instruction to transmit the traffic condition information, to the server device 12. The transmission unit is included in the travel support device 11.

  Next, a server reception unit (not shown) receives a traffic condition information transmission instruction from the driving support device 11. The server receiving unit includes the server receiving unit.

  Next, the server transmission unit 122 acquires all the traffic situation information of FIG. 6 stored in the server traffic situation information storage unit 121 and transmits it to the driving support device 11. In addition, the acquisition of the said traffic condition information may be performed by the server traffic condition information acquisition part which is not shown in figure, for example. In this case, the server traffic condition information acquisition unit is provided in the server device 12.

  Next, the receiving part 111 which comprises the driving assistance apparatus 11 receives the traffic condition information of FIG. The received traffic situation information is stored in a predetermined storage area by, for example, a storage unit (not shown).

  Here, it is assumed that the current position is outside the driving support area. The current position is indicated by the current position information acquired by the current position information acquisition unit 112. In addition, the travel support area is indicated by one or more pieces of position information included in the traffic condition information of FIG. In this case, the driving support device 11 controls the electric wheelchair or performs a predetermined process according to the instruction received by the receiving unit 113. For example, when the reception unit 113 receives an acceleration instruction, the driving support device 11 accelerates the electric wheelchair according to the acceleration instruction. For example, when the reception unit 113 receives an instruction to turn off the power, the driving support device 11 turns off the power of the electric wheelchair according to the instruction to turn off the power.

  Next, it is assumed that the determination unit 114 determines that the current position is within the driving support area. The driving support area is assumed to be a driving support area indicated by one or more pieces of position information included in the traffic condition information of “ID = 012” in FIG. Then, the determination unit 114 determines to perform driving support.

  Next, it is assumed that the user performs an operation for accelerating the electric wheelchair. Then, the reception unit 113 receives an acceleration instruction. Further, it is assumed that the acceleration instruction is an instruction for accelerating at an acceleration “8 km / s · s”. The “s · s” represents the square of the second. Here, it is assumed that the driving support execution condition is a condition relating to acceleration “acceleration> 5 km / s · s”. The driving support execution condition means that the acceleration exceeds “5 km / s · s”.

  Next, the driving support unit 115 determines that the acceleration “8 km / s · s” instructed by the acceleration instruction satisfies the driving support execution condition “acceleration> 5 km / s · s”. Then, the driving support unit 115 controls the acceleration of the electric wheelchair so as to accelerate at an acceleration that does not satisfy the driving support execution condition. For example, the travel support unit 115 controls a motor included in the electric wheelchair so as to accelerate at an acceleration of “5 km / s · s”.

(Example 2)
In this example, an example of controlling the speed in the driving support area will be described.

  First, similarly to Example 1, it is assumed that the electric wheelchair is traveling in the travel support area while accelerating at an acceleration of “5 km / s · s”. Here, it is assumed that the driving support execution condition is a condition relating to speed “speed> 20 km / h”. The driving support execution condition means that the speed exceeds “20 km / h”.

  Next, it is assumed that the speed of the electric wheelchair reaches “20 km / h” as a result of the above acceleration. Then, the driving support unit 115 determines that the speed “20 km / h” satisfies the driving support execution condition “speed> 20 km / h”. Then, the travel support unit 115 controls the speed of the electric wheelchair so that the travel support unit 115 travels at a speed that does not satisfy the travel support execution condition. For example, the travel support unit 115 controls a motor included in the electric wheelchair so as to travel at a speed of “20 km / h”.

(Example 3)
In this example, an example of notifying the user that the vehicle is in the driving support area in the driving support area will be described. The notification means is assumed to be sound output. That is, it is assumed that sound output is performed in advance in the driving support area.

  First, similarly to Example 1, it is assumed that the electric wheelchair is traveling.

  Next, it is assumed that the determination unit 114 determines that the current position is within the driving support area. The travel support area is assumed to be a travel support area indicated by one or more pieces of position information included in the traffic condition information of “ID = 018” in FIG. Then, the determination unit 114 determines to perform driving support.

  Next, the driving support unit 115 performs sound output using a speaker included in the electric wheelchair. The output sound is, for example, a so-called beep sound or a so-called warning sound.

  Further, it is assumed that the electric wheelchair continues to travel and moves out of the travel support area. Then, the determination unit 114 determines that the current position is outside the driving support area. Then, the determination unit 114 determines not to perform driving support.

  Next, the driving support unit 115 ends the sound output.

  As described above, according to the driving support system 1 according to the present embodiment, it is possible to support the driving of the low-speed moving body according to the traffic situation. For example, according to the driving support system 1 according to the present embodiment, the speed and acceleration of a low-speed moving body can be controlled in accordance with the situation of occurrence of a traffic accident or the situation of a passerby. Further, for example, according to the driving support system 1 according to the present embodiment, the user is notified that attention is required for driving according to the situation of the occurrence of a traffic accident or the situation of a passerby. be able to.

  In the present embodiment, the traffic condition information may include travel support content information indicating the content of travel support. In this case, the determination unit 114 acquires the travel support content information included in the traffic situation information determined to satisfy the travel support determination condition. In this case, the driving support unit 115 performs driving support of the content indicated by the driving support content information acquired by the determination unit 114.

  Further, in the present embodiment, it is determined whether or not the relationship between the current position indicated by the current position information and the position indicated by the one or more position information included in the traffic condition information satisfies the driving support determination condition, and the driving support is executed. The determination unit 114 may determine whether the determination target based on the condition satisfies the driving support execution condition. In this case, the driving support unit 115 determines that the determination unit 114 satisfies the driving support determination condition when the relationship between the current position indicated by the current position information and the position indicated by one or more pieces of position information included in the traffic condition information is satisfied. When it is determined that the target of the determination based on the support execution condition satisfies the driving support execution condition, the driving support having a predetermined content is performed.

(Embodiment 2)
In the present embodiment, a description will be given of a traveling support device 21 that supports traveling of a low-speed moving body in accordance with the situation of a passerby or the state of a low-speed moving body.

  Note that the driving support device 21 in the present embodiment is normally mounted on a low-speed moving body, as in the first embodiment.

  FIG. 7 is a block diagram of the driving support device 21 in the present embodiment. The travel support device 21 includes a situation state related information acquisition unit 211, a reception unit 212, a determination unit 213, and a travel support unit 214. Note that the processing, operation, and the like in the reception unit 212 are the same as the processing, operation, and the like in the reception unit 113 of Embodiment 1, and thus description thereof is omitted. Further, the processing and operation in the driving support unit 214 are the same as the processing and operation in the driving support unit 115 of Embodiment 1 except that the driving support is performed when the determination unit 213 determines to perform driving support. Therefore, explanation is omitted.

  The situation status related information acquisition unit 211 acquires status status related information. The “situation state related information” is information relating to, for example, the situation of passers-by and the state of the low-speed moving body. Further, the “situation state related information” is also information indicating, for example, the situation of a passerby or the state of a low-speed moving body. “The situation of passers-by” includes the presence or absence of passers-by and the number of passers-by. Further, the “state of the moving body” is usually a state of the remaining amount of fuel of the low speed moving body. The “fuel” is usually a battery. Further, the “remaining fuel state” is, for example, whether there is a remaining fuel amount or the ratio of the remaining fuel amount. In addition, the situation state related information acquisition unit 211 normally acquires the situation state related information periodically.

  In addition, when acquiring the situation state related information regarding the passerby situation (hereinafter referred to as passerby situation related information as appropriate), the situation state related information acquisition unit 211, for example, As appropriate, the front image is acquired. The front image may be a video having the two or more images. Then, the situation state related information acquisition unit 211 performs image processing on the acquired front image and detects a person in the image. Then, the situation state related information acquisition unit 211 determines the situation of the passerby using the detection result of the person. Then, the situation state related information acquisition unit 211 acquires the passerby situation related information according to the determination result of the passerby situation.

  Further, in this case, the situation state related information acquisition unit 211 usually receives a front image from an image sensor (solid-state imaging device) such as CMOS or CCD, or a camera (digital still camera, digital video camera) using the image sensor. To get. In this case, the situation state related information acquisition unit 211 may include, for example, these devices.

In this case, the situation state related information acquisition unit 211 may include these devices or may be realized by these devices.

  The status state related information may be, for example, information related to the surrounding environment (hereinafter referred to as ambient environment related information as appropriate). The “ambient environment” is usually the weather. That is, the ambient environment related information is usually information indicating weather, precipitation, wind speed, wind direction, and the like. The ambient environment information may be information indicating whether it is raining, for example.

  Moreover, when acquiring the status state related information regarding the surrounding environment, the status state related information acquisition unit 211 normally acquires the ambient environment related information from a device such as an illuminometer, a cloud meter, or an anemometer. In this case, the situation state related information acquisition unit 211 may have, for example, these devices or may be realized by these devices.

  Further, the processing procedure of the status state related information acquisition unit 211 is usually realized by software, and the software is recorded in a recording medium such as a ROM.

  The determination unit 213 determines whether to perform driving support. The determination unit 213 normally holds in advance driving support determination conditions for determining whether to perform driving support. Then, the determination unit 213 determines whether to perform driving support using the driving support determination condition. Specifically, the determination unit 213 determines whether the determination target based on the driving support determination condition satisfies the driving support determination condition. Then, the determination unit 213 determines that the driving support is performed when the target of the determination based on the driving support determination condition satisfies the driving support determination condition.

  In the present embodiment, the driving support determination condition is different from the first embodiment in terms of conditions regarding passersby conditions, low-speed moving bodies, and the like. The “passerby situation” is the passerby situation indicated by the situation state related information acquired by the situation state related information acquisition unit 211. Further, the “state of the low-speed moving body” is the state of the low-speed moving body indicated by the situation state related information acquired by the situation state related information acquisition unit 211. In addition, the driving support determination condition in the present embodiment may be a condition related to the surrounding environment, for example. The “ambient environment” is the ambient environment indicated by the ambient environment related information acquired by the situation state related information acquisition unit 211.

  That is, the determination unit 213 determines whether or not the situation state related information acquired by the situation state related information acquisition unit 211 satisfies the driving support determination condition. Then, the determination unit 213 determines to perform driving support when the situation state related information satisfies the driving support determination condition.

  The determination unit 213 can be usually realized by an MPU, a memory, or the like. Also, the processing procedure of the determination unit 213 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. Note that the determination unit 213 and the like may be realized by hardware (a dedicated circuit).

  Next, the overall operation of the driving support device 21 will be described using the flowchart of FIG.

When it satisfies, it progresses to step S806, and when that is not right, it progresses to step S814.

  (Step S806) The driving support unit 214 determines the content of the driving support. The determination is made using, for example, information indicating the content of the driving support stored in a predetermined storage area. If the speed is to be controlled, the process proceeds to step S807. If the acceleration is to be controlled, the process proceeds to step S810. If the output is to be controlled, the process proceeds to step S813.

  (Step S815) The driving support device 21 performs a power-off process. Then, the process returns to step S801.

  In the flowchart of FIG. 8, the process may be terminated by powering off or a process termination interrupt.

(Concrete example)
Next, a specific example of the operation of the driving support device 21 will be described. In this specific example, the low speed moving body is an electric wheelchair. Moreover, the driving assistance apparatus 21 shall be a control apparatus of an electric wheelchair. In addition, the situation state related information acquisition unit 211 included in the driving support device 21 periodically acquires the state state related information from when the electric wheelchair is turned on until the power is turned off.

(Example 1)
In this example, an example of controlling acceleration or speed when the remaining amount of fuel is small will be described. In this example, it is assumed that the fuel for the electric wheelchair is a battery. Further, it is assumed that the driving support determination condition is “remaining battery level ≦ 30%”. The driving support determination condition means that the remaining battery level is 30% or less.

  First, it is assumed that the user gets on the electric wheelchair, turns on the electric wheelchair, and starts running. Due to the traveling, the remaining battery capacity of the electric wheelchair gradually decreases.

  Here, it is assumed that the situation state related information acquisition unit 211 acquires the moving body state related information “30%” indicating the remaining battery level. Then, the determination unit 213 determines that the moving body state related information “30%” satisfies the driving support determination condition “remaining battery ≦ 30%”. Then, the determination unit 213 determines to perform driving support.

  Next, it is assumed that the user performs an operation for accelerating the electric wheelchair. Then, the reception unit 212 receives an acceleration instruction. Further, it is assumed that the acceleration instruction is an instruction for accelerating at an acceleration “8 km / s · s”. The “s · s” represents the square of the second. Here, it is assumed that the driving support execution condition is a condition relating to acceleration “acceleration> 5 km / s · s”. The driving support execution condition means that the acceleration exceeds “5 km / s · s”.

  Next, the driving support unit 214 determines that the acceleration “8 km / s · s” instructed by the acceleration instruction satisfies the driving support execution condition “acceleration> 5 km / s · s”. Then, the travel support unit 214 controls the acceleration of the electric wheelchair so as to accelerate at an acceleration that does not satisfy the travel support execution condition. For example, the travel support unit 214 controls a motor included in the electric wheelchair so as to accelerate at an acceleration of “5 km / s · s”.

  Further, for example, it is assumed that the electric wheelchair is running while accelerating at an acceleration of “5 km / s · s” as described above. Here, it is assumed that the driving support execution condition is a condition relating to speed “speed> 20 km / h”. The driving support execution condition means that the speed exceeds “20 km / h”.

  Next, it is assumed that the speed of the electric wheelchair reaches “20 km / h” as a result of the above acceleration. Then, the driving support unit 214 determines that the speed “20 km / h” satisfies the driving support execution condition “speed> 20 km / h”. Then, the travel support unit 214 controls the speed of the electric wheelchair so as to travel at a speed that does not satisfy the travel support execution condition. For example, the travel support unit 214 controls a motor included in the electric wheelchair so as to travel at a speed of “20 km / h”.

(Example 2)
In this example, an example will be described in which acceleration or speed is controlled according to a passerby's situation. In this example, it is assumed that the driving support determination condition is “passerby = yes”. The driving support determination condition means that there is a passerby.

  First, similarly to Example 1, it is assumed that the electric wheelchair is traveling.

  Here, it is assumed that the situation state related information acquisition unit 211 has acquired passerby situation related information “present” indicating that there is a passerby. At this time, for example, the situation state related information acquisition unit 211 acquires a front image, performs image processing on the acquired front image, and detects a person in the front image. If a person can be detected from the front image, for example, the situation state related information acquisition unit 211 acquires passer situation related information “present” indicating that there is a passerby. When a person cannot be detected from the front image, for example, the situation state related information acquisition unit 211 acquires passer situation information “none” indicating that no passer is present.

  Next, the determination unit 213 determines that the passerby state related information “Yes” satisfies the driving support determination condition “Passer = Yes”. Then, the determination unit 213 determines to perform driving support.
