JP6639429B2 - Vehicle control server, mobile terminal, and program for controlling vehicle according to user's mobile stay status - Google Patents

Description

  The present invention relates to a technique for controlling a vehicle control device mounted on a vehicle via a network.

  Mistakes in humans driving vehicles such as cars, buses and trucks have resulted in constant loss of life and economic losses. In order to suppress or prevent this, there is a technology that grasps the physical condition of the driver and predicts and reduces driving errors.

  For example, there is a technique for supplementing information at the time of living or sleeping as information at the time of driving (for example, see Patent Document 1). According to this technology, a sensor attached to a user measures a physical condition based on biological information such as a heart rate and a blood pressure. According to the physical condition of the user who drives the vehicle, a driving assistance device provided in the vehicle assists steering operation and pedal depression. As a result, driving errors can be reduced as much as possible.

FIG. 9 is an explanatory diagram illustrating a second control condition table. FIG. 3 is an external view illustrating information devices around a user during driving when the present invention is implemented by a mobile terminal.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an external view illustrating information devices around a user during driving when the present invention is implemented by a vehicle control server.

According to FIG. 1, the vehicle control server 1 communicates via a network with a portable terminal 2 carried by a user and a vehicle terminal 3 connected to a vehicle control device of the vehicle.
The vehicle control server 1 of the present invention estimates a time-series moving stay state as the “action state” of the user from the time-series position information obtained from the mobile terminal 2. Then, the vehicle control server 1 transmits to the vehicle terminal 3 a vehicle control policy corresponding to an action condition based on the time-series moving stay state (action state) of the user.

  ADVANTAGE OF THE INVENTION According to this invention, in order to estimate "the action state" which affects a driving error of a user, a dedicated sensor or device is not required, and only the positional information obtained from a widely used portable terminal is used. . In particular, a mobile terminal such as a smartphone has a small burden on users since it is customary to always carry it.

The vehicle terminal 3 can communicate with a vehicle control device via an in-vehicle network such as a CAN (Controller Area Network). CAN refers to a standard that has enhanced noise resistance and is used for data transfer between interconnected devices.
The vehicle terminal 3 may be a device installed in the vehicle, for example, as in a navigation system. In that case, the vehicle terminal 3 can hold the map data and present information such as a traveling road to the user according to the current position. Of course, the vehicle terminal 3 is not limited to a navigation system.

According to the present invention, there are, for example, the following for each category as control targets of the vehicle control policy.
(Category 1: Automated driving control): Control of the running behavior of the vehicle Front vehicle spacing Braking (braking distance to stop, forward acceleration, tire speed, etc.)
Acceleration / deceleration, speed, steering (lateral acceleration, front wheel turning angle, etc.)
Drive (vehicle speed, rear acceleration, tire rotation, etc.)
Distance to front / rear / side obstacles Lane departure range ・ ・ ・ ・ ・ ・
(Category 2: Vehicle environment control): Control of occupant's surrounding environment Seat / handle position (Massage On / Off)

(Category 4: Body control): Control of running stability Tire pressure Suspension / stabilizer hardness Vehicle height Rear spoiler shape ・ ・ ・ ・ ・ ・
(Category 5: User interface control)
Screen (display characters, illuminance, color)
Voice (voice speed, volume, timbre)
...
(Category 6: Navigation control)
Route guidance based on the size of the road Route guidance with a small number of accidents

  FIG. 2 is a functional configuration diagram of the vehicle control server according to the present invention.

According to FIG. 2, the vehicle control server 1 includes a log accumulation unit 10, a mobile terminal identification unit 11, a moving stay analysis unit 12, a control condition table 130, a vehicle control policy selection unit 13, and a vehicle control policy transmission. And a vehicle position acquisition unit 15. These functional components are realized by executing a program that causes a computer mounted on the device to function. In addition, the processing flow of these functional components can be understood as a vehicle control method of the device.
Of course, the function of the present invention in FIG. 2 is configured as a vehicle control server, but may be configured as a portable terminal as shown in FIG. 7 described later.

[Log accumulation unit 10]
The log storage unit 10 stores logs including date and time and position information in the mobile terminal 2.

  FIG. 3 is a table showing logs including date and time and position information on the mobile terminal, which are stored in the log storage unit.

The log is stored by associating “date and time and position information” (time-sequential position information) for each mobile terminal (terminal ID).
The “time-series position information” is a communication log based on the base station positioning of the mobile terminal 2 and may be collected by a communication facility device of the mobile phone network. The base station positioning is not limited to the base station of the mobile phone network, but may be a WiFi access point. In this case, the vehicle control server 1 acquires the time-series position information of the mobile terminal from the communication facility device of the communication business.
According to the base station positioning, there is no need for the mobile terminal 2 to perform positioning itself, and it is not necessary to transmit the position information to the vehicle control server 1 via the network. According to the communication facility device of the communication carrier, the position information of the mobile terminal 2 is constantly collected.

  Needless to say, the time-series position information may be acquired by a positioning unit of a GPS (Global Positioning System) mounted on the portable terminal 2 itself. For example, positioning is performed at predetermined time intervals or at predetermined moving distances by an application installed in the mobile terminal, and the position information is transmitted to the vehicle control server 1.

  The “terminal ID” may be, for example, a unique identification number or a telephone number of a mobile terminal, or a MAC (Media Access Control) address of WiFi or Bluetooth (registered trademark). Of course, it may be an ID for user identification (for example, a mail address) paid out for each service.

[Mobile terminal identification unit 11]
The mobile terminal specifying unit 11 specifies a mobile terminal of a user riding in the vehicle. Specifically, a terminal ID of one or more mobile terminals 2 is specified for a vehicle ID of the vehicle terminal 3 to which the vehicle control device is connected. For example, there are the following three embodiments.

(First Embodiment for Specifying Mobile Terminal)
When the distance between the current position information acquired from the vehicle terminal 3 and the current position information of the mobile terminal 2 is within a predetermined distance, the mobile terminal identification unit 11 sends the user of the mobile terminal 2 to the vehicle of the vehicle terminal 3. Identifies that is on board. That is, the vehicle ID and the terminal ID whose position information matches are associated with each other. When the vehicle is running, the position information of the mobile terminal of the driver user always matches the position information of the vehicle terminal of the vehicle.
In the case of the first embodiment, since it is necessary to acquire the current position information from the vehicle terminal 3, according to FIG. The vehicle terminal 3 acquires the current position information by the GPS positioning unit mounted on the vehicle terminal 3 and transmits the current position information to the vehicle control server 1.

(Second embodiment for specifying mobile terminal)
When receiving information from the vehicle terminal 3 that the user of the mobile terminal has boarded, the mobile terminal specifying unit 11 specifies the mobile terminal 2 in association with the vehicle terminal 3. That is, the function of specifying the terminal ID is realized in the vehicle terminal 3.
For example, the mobile terminal 2 sends an e-mail or an SMS (Short Message System) (or telephone) to the vehicle terminal 3. On the other hand, the vehicle terminal 3 specifies the terminal ID of the user, for example, when receiving the mail. Further, when the vehicle terminal 3 is connected to the mobile terminal 2 via Bluetooth or WiFi, the terminal ID may be specified from the connection signal. Then, the vehicle terminal 3 transmits the vehicle ID and the terminal ID to the vehicle control server 1 in association with each other.

(Third Embodiment for Specifying Mobile Terminal)
The mobile terminal identification unit 11 identifies the mobile terminal 2 in association with the vehicle terminal 3 when receiving information from the mobile terminal 2 that the user has boarded the vehicle terminal based on a user operation. That is, the portable terminal 2 has a function of specifying the vehicle ID.
For example, an NFC (Near Filed Communication) tag is installed in the vehicle, and the mobile terminal 2 reads the tag to identify the vehicle ID. Further, when the mobile terminal 2 is connected to the vehicle terminal 3 via Bluetooth or WiFi, the mobile terminal 2 may specify the vehicle ID from the connection signal. Then, the mobile terminal 2 associates the vehicle ID with the terminal ID and transmits the vehicle ID to the vehicle control server 1.

[Mobile stay analysis unit 12]
The mobile stay analysis unit 12 estimates “mobile stay status for each time zone” from “date and time and position information” in the mobile terminal 2. Here, the mobile terminal to be analyzed is based on the mobile terminal specified by the mobile terminal specifying unit 11.
When the position information continues to be within the predetermined range for the predetermined time or more, the moving stay analysis unit 12 may determine that the time zone is in the “stay state”. Further, the predetermined range may be derived by clustering the position information. Furthermore, in the case of base station positioning, time-series position information may be divided into time windows, and “movement” and “stay” may be determined from a probability distribution based on a plurality of base station position information for each time window. .
Further, when it is determined that “stay”, the center of gravity of a large number of pieces of position information concentrated in a predetermined range may be set as the place of stay.

FIG. 4 is a table showing a mobile stay state in the mobile terminal analyzed by the mobile stay analysis unit.
According to FIG. 4, the start date and time and the end date and time (time zone), the moving stay state (moving state or stay state), and the positional information in the case of the stay state are analyzed in association with each other.

[Vehicle control policy selector 13 / control condition table 130]
The control condition table 130 stores “behavior conditions” based on the relation of the moving stay state for each time zone and “vehicle control policy” in association with each other.
The vehicle control policy selection unit 13 uses the control condition table 130 to select a vehicle control policy corresponding to an action condition based on the specified mobile terminal's moving stay state for each time zone.

  The “vehicle control policy” is one in which one of a plurality of parameters of different levels is set for each control target in the vehicle control device of the vehicle. That is, the vehicle control policy sets different levels of parameters for the same control target in accordance with the user's feeling of fatigue and / or tension.

  The vehicle control policy selection unit 13 and the control condition table 130 will be described below as well as a basic embodiment and three complementary embodiments.

<Basic embodiment in selecting vehicle control policy>
FIG. 5 is an explanatory diagram illustrating a first control condition table.

FIG. 5A is a table in which a vehicle control policy is associated with each action condition. Examples of the “action condition” include the following.
(Behavior condition 1)
"Continuous stay time <8 hours at the place of stay at 2:00 AM on the day of travel"
Generally, at around 2:00 AM at midnight, he stays at home and sleeps, and his stay time is 8 hours or more. The user corresponding to this behavioral condition has not been able to sufficiently secure the sleep time in the middle of the night, and is likely to have a feeling of fatigue.
(Behavior condition 2)
"A total of one week before traveling for the continuous stay time at the place of stay at 2:00 AM each day ≥ 100 hours"
The user who falls under this behavioral condition is able to secure a sufficient amount of sleep time almost every day, and is likely to have no fatigue.
(Behavior condition 3)
"From 9:00 PM to 11:30 PM on the day before traveling, the staying time at a different place of stay from the first staying place at 5:00 PM on the day before traveling and the second staying place at 2:00 AM on the day of travel ≥ 1 hour"
At around PM5: 00 in the evening, she generally stays and works at the company, and at around 2:00 AM in the evening, she generally stays at home and sleeps. The user corresponding to this action condition stays at a different place from the company and home from PM9: 00 to PM11: 30 on the day before the run, and for example, after leaving the office on the eve of the day, drinking at an izakaya (different point) before returning home. It is highly likely that you were. In such a case, there is a high possibility that the person has a feeling of fatigue weak against motion sickness.
(Behavior condition 4)
"Moving time of the previous day ≥ 5 hours"
The user corresponding to this behavior condition is likely to have a feeling of fatigue due to long-time movement.

FIG. 5B is a table in which parameters of different levels are associated with each control target.
According to FIG. 5 (b), as the control targets, “vehicle distance ahead”, “braking distance”, “acceleration”, “tire pressure”, and “navigation” are exemplified. In addition, three levels A to C are associated with each control target.
The “front vehicle interval” is a value in which a different hourly speed is set as the lower limit of the hourly speed that maintains the inter-vehicle distance of, for example, vehicle speed (hours) × 1 m. For example, the level A is controlled so as to maintain an inter-vehicle distance of 30 m when the vehicle speed is 30 km / h, and is controlled in consideration of a case where the reaction of the driving operation by the user is slow. On the other hand, at the level C, the inter-vehicle distance is not controlled up to a vehicle speed of 80 km / h, and it is considered that the driving operation by the user is sufficient.
The “braking distance” is controlled by a different formula based on the vehicle speed. For example, at the level A, the braking distance is controlled to be long in consideration of the case where the reaction of the driving operation by the user is slow. On the other hand, at level C, the braking distance is controlled to be short, assuming that the driving operation by the user is sufficient.
Regarding the “acceleration”, for example, the acceleration of the level A is limited in consideration of the user's feeling of fatigue. On the other hand, at the level C, there is no feeling of fatigue of the user, and the limitation of the acceleration is small.
Regarding the "tire pressure", for example, level A is controlled to a soft and stable running property by reducing the tire pressure in consideration of the user's feeling of fatigue. On the other hand, at the level C, assuming that the user does not feel tired, the tire air pressure is increased and the running performance is controlled to be agile.
Regarding “navigation”, for example, level A is controlled in consideration of the user's feeling of fatigue so as not to guide the user to a narrow-width road when guiding the traveling route. On the other hand, the level C guides the traveling route regardless of the width, assuming that the user does not feel tired.

Here, according to the table of FIG. 5A described above, a “vehicle control policy” is associated with each action condition. “A1” means that a parameter of level A is set for the control target 1. “C3” means that a parameter of level C is set for the control target 3.
A vehicle control policy A1, A2, A3, A4, A5 is associated with the action condition 1.
The vehicle control policy C1, C2, C3, C4, C5 is associated with the action condition 2.
A vehicle control policy A1, A2, A3, B4, A5 is associated with the action condition 3.
A vehicle control policy B1, B2, B3, B4, B5 is associated with the action condition 4.
For example, a user (action condition 3) “had stayed at an izakaya different from his / her company at PM5: 00 on the day before traveling and at home at AM2: 00 on the day of traveling around 10:00 PM or more on the day before traveling 10:00 or more,” For vehicles, the distance between the vehicles ahead is 30 km / h or more and the vehicle speed (speed) × 1 m or more (A1), and the braking distance is the distance obtained by dividing the square of the vehicle speed (m / s) by 5 (A2). The acceleration is controlled so as to be less than 0.5G (A3), the tire pressure is set to a standard value (B4), and the navigation is guided so as to give priority to a width of 10 m or more (A5).

<First Complementary Embodiment in Selecting Vehicle Control Policy>
The action condition of the control condition table 130 may be based on the relationship between the mobile stay state of each of the plurality of mobile terminals. This action condition is set complementarily to the basic embodiment described above.
That is, when the mobile terminal specifying unit 11 specifies “a plurality of mobile terminals” for the same vehicle, the vehicle control policy selecting unit 13 uses the control condition table 130 to specify a plurality of the specified mobile terminals. A vehicle control policy further corresponding to the action condition based on the moving stay state for each time period is selected.

  FIG. 6 is an explanatory diagram illustrating a second control condition table.

FIG. 6A is a table that defines comparison conditions in which a plurality of users are related. For example, it is assumed that the following comparison conditions are defined according to the human relationship based on the place of stay.
(Comparison condition 1 for multiple users)
"Percentage of time the terminal stayed within a distance of 30m between 1:00 AM and 5:00 AM in the past month"
(Comparison condition 2 for multiple users)
"Percentage of time during which the terminal stayed within a distance of 30 m between 10:00 AM and 5:00 PM on weekdays during the past two weeks"
(Comparison condition 3 for multiple users)
"The sum of the time during which the terminal stays between 1:00 AM and 5:00 AM was within a distance of 30 m during the past week before and after 5/3, 8/15 and 1/1 in the past year"
(Comparison condition 4 for multiple users)
"Time / distance of the same date and time travel route of the terminal matches the weekend / holiday travel of the past year"

According to FIG. 6B, a table is defined in which the action conditions relating to a plurality of users are defined using the comparison condition of FIG. 6A.
(Actual conditions of multiple users 1)
"Number of terminals whose comparison condition 1 is 80% or more ≧ 2"
When the occupant is likely to be a family member, the vehicle is controlled so that acceleration and deceleration are moderate so as not to cause anxiety. However, users of different families living in an apartment house may also fall under this comparison condition 1.
(Actual conditions of multiple users 2)
"Comparison condition 2 is 50% or more, and comparison condition 4 is 1 hour / 15 km or more terminals>2"
If the occupant is likely to be a company colleague, the vehicle is controlled so that agile driving reduces the occupant's irritation.
(Action condition 3 of multiple users)
"Number of terminals where comparison condition 1 is less than 10% and comparison condition 3 is 8 hours or more ≧ 2"
If the occupant is likely to be a best friend or lover, the vehicle is controlled so as to increase the distance between the front vehicles so as to give a sense of security.

  As described above, when a plurality of users board the same vehicle, the vehicle can be controlled according to the human relationship between the users.

<Second Complementary Embodiment in Selecting Vehicle Control Policy>
The vehicle control policy selection unit 13 is a vehicle that further corresponds to an action condition based on a relationship between the position information of the mobile terminal 2 specified by the mobile terminal specification unit 11 in the past predetermined period and the position information acquired from the vehicle terminal 3. Select a control policy. This action condition is set complementarily to the basic embodiment described above.
In the case of the second complementary embodiment, since it is necessary to obtain the current position information from the vehicle terminal 3, according to FIG.

For example, the action condition can be determined as follows.
(Position Action Condition 1) When the current position of the vehicle is not included in the position information of the portable terminal 2 for the past two years, the control is performed to change the level of a predetermined control target to a different parameter level. For example, level C is changed to level B.
(Position Behavior Condition 2) When the current position of the vehicle is included in the position information of the portable terminal 2 five times or more in the past year, the predetermined control target is controlled to change to a different parameter level. For example, level A is changed to level B.

That is, the vehicle control policy is changed based on how often the driving user has visited the traveling road in the past. For example, if no visit has been made in the past, or if a considerable number of years have passed since the last visit, the vehicle is controlled so that acceleration and deceleration are moderate so as not to give the user anxiety. I do. On the other hand, if the user frequently visits the vehicle, the vehicle is controlled so as to suppress the user's irritation by agile driving.
Note that, in the second complementary embodiment, “the mobile terminal specified by the mobile terminal specifying unit 11 is replaced by“ the mobile terminal specified by the mobile terminal specifying unit 11 ” The position information of the vehicle terminal 3 on which the second user is boarding for a predetermined period in the past may be used.

<Third Complementary Embodiment in Selecting Vehicle Control Policy>
It is preferable that the log of the mobile terminal further includes a user usage state for the mobile terminal. The “user use state” means, for example, communication from an application based on a user operation. In other words, it is not the communication of the application executed on the back end of the mobile terminal but the communication of the application executed by the user operation on the front end. In this case, the log records the user use state (in the simplest case, “in use” and “not in use”) together with the date and time and the position information.

The action condition in the control condition table 130 is further based on the relationship between the user usage status of the mobile terminal.
Further, the vehicle control policy selection unit 13 uses the control condition table 130 to select a vehicle control policy that further corresponds to an action condition based on the mobile stay state and the user use state of the mobile terminal for each time zone.

For example, the following action condition may be set.
(Behavior conditions for user usage status)
"Continuous user usage time at the place of stay at 2:00 AM on the day of travel> 3 hours"
In general, if the user stays at home at around 2:00 AM at midnight and the user's usage status of the mobile terminal is “in use” for 3 hours or more, the user who meets this action condition has sufficient sleep time Not likely, likely to have a feeling of fatigue.
In this case, it is possible to change the level of the parameter in the predetermined control target selected by the above-described basic embodiment. For example, for a predetermined control target, the level B selected according to the basic embodiment can be changed to the level A.

  Note that the user usage state may include a communication destination and a communication amount. The usage state of the application may be estimated by constantly monitoring a change pattern of the communication amount per unit time using information that can be collected by the communication business facility.

[Vehicle control policy transmission unit 14]
The vehicle control policy transmission unit 14 transmits the selected vehicle control policy to the vehicle terminal 3. The vehicle terminal 3 is connected to the vehicle control device and controls vehicle information transmitted and received within the CAN of the vehicle.

  According to the above-described embodiment, the present invention has been described as being realized by the vehicle control server connected to the network. Of course, the functional configuration of the present invention is not limited to a server, and may be implemented in a portable terminal owned by a user.

  FIG. 7 is an external view illustrating information devices around the user during driving when the present invention is implemented by a mobile terminal.

  According to FIG. 7, the mobile terminal 2 has basically the same functional configuration as the above-described vehicle control server. For example, the mobile terminal 2 is always carried by the user, and connects to the CAN of the vehicle via radio while the user is driving. Thereby, the mobile terminal 2 can directly transmit the vehicle control policy to the CAN without using the vehicle control server 1 and control the vehicle control device.

As described above in detail, according to the vehicle control server, the mobile terminal, and the program of the present invention, the vehicle can be controlled according to the user's action state.
According to the present invention, it is possible to select a vehicle control policy based on the control condition table using the “moving stay state” as the user's action state, and transmit the vehicle control policy to the vehicle terminal or the vehicle control device. . The user's mobile stay state has a high correlation with the user's physical condition, such as working hours, staying at home (resting time), and drinking the night before. By controlling the vehicle using the traveling stay state, the risk of an accident can be reduced and a comfortable driving environment can be provided to the user.

  For the above-described various embodiments of the present invention, various changes, modifications, and omissions in the scope of the technical idea and viewpoint of the present invention can be easily performed by those skilled in the art. The foregoing description is merely an example, and is not intended to be limiting. The invention is limited only by the following claims and equivalents thereof.
