Even if the driver wants to park the vehicle in a safe zone for charging the portable terminal, there may occur a case where the vehicle cannot be parked on the parking-prohibited road or the destination cannot be reached at a predetermined time because unnecessary time is spent for charging even if the vehicle is parked in a parking-possible area. Therefore, when the remaining battery capacity of the mobile terminal device in use is insufficient during driving, how to charge the mobile terminal device so as to enable continuous use while driving normally is a problem that cannot be solved by the prior art.

Detailed Description
Embodiments of the present invention are described below with reference to the drawings.
First, the configuration and operation of the driving control device according to embodiment 1 of the present invention will be described with reference to fig. 1, 2, and 3.
Fig. 1 is a schematic block diagram of a driving control device according to embodiment 1 of the present invention. Reference numeral 10 denotes a driving control device according to the present invention, and includes an in-vehicle device 100, a driving mode switching unit 200, and a mobile terminal 300. The vehicle of the present invention has an automatic driving mode and a manual driving mode, and the driving mode switching unit 200 can switch between the two modes. The manual driving mode is a mode in which the vehicle travels in accordance with an acceleration operation, a deceleration operation, a shift operation, a steering operation, and the like by the driver, as in a normal non-autonomous vehicle. The automatic driving mode is a running mode in which the vehicle itself can change the course while automatically avoiding an obstacle even if an operation such as an acceleration operation, a deceleration operation, a shift operation, and a steering wheel operation is not performed. The vehicle is equipped with an in-vehicle device 100, and the portable terminal 300 may be connected to the in-vehicle device 100 in a wired or wireless manner. As shown in fig. 1, the driving control apparatus of the present invention includes: a central control unit 101, a connection unit 102, a remaining power detection unit 103, a notification unit 104, a driving mode detection unit 121, a mode switching control unit 122, and the like.
Next, the configuration of the driving control device according to embodiment 1 of the present invention will be described in detail.
The connection unit 102 connects the in-vehicle device 100 and the portable terminal 300 by wire (USB, etc.) or wirelessly (bluetooth, wireless LAN, etc.), and allows the in-vehicle device 100 and the portable terminal 300 to communicate various data and contents (songs, moving images, etc.).
The remaining power detection unit 103 detects the remaining battery power of the mobile terminal 300. Specifically, the remaining capacity detection unit 103 can read out data of the remaining capacity of the battery from the connected portable terminal 300 via the connection unit 102.
The driving mode detection unit 121 is configured to detect the current driving mode of the vehicle by the driving mode switching unit 200 of the vehicle. That is, when the driving mode switching unit 200 receives a request from the driving mode detecting unit 121, the driving mode switching unit 200 reads out the stored data from the storage unit and transmits the data to the driving mode detecting unit 121, thereby detecting the current driving mode (not shown).
The driving mode switching unit 200 of the vehicle switches the driving mode of the vehicle from one of the manual driving mode and the automatic driving mode to the other in accordance with an operation of the user. For example, when a driving mode set in advance is switched to another driving mode in response to a selection operation by a user, or when an acceleration operation, a deceleration operation, a shift operation, a steering operation, or the like is detected from the user in the automatic driving mode, the driving mode is switched to the manual driving mode. When the remaining power detection unit 103 detects that the remaining battery power of the mobile terminal 300 is equal to or less than the 1 st predetermined value and the driving mode detection unit 121 detects that the current driving mode is the manual driving mode, the mode switching control unit 122 transmits a switching signal to the driving mode switching unit 200 to switch the manual driving mode to the automatic driving mode. The 1 st predetermined value may be a value set in advance at the product shipment stage or may be a value set arbitrarily by the user, and for example, the 1 st predetermined value may be set to a value larger than the electric quantity value, assuming that the required electric quantity (the currently used resource) such as the playback of a song or the like can be maintained until the charging operation is started after the user knows that the remaining electric quantity becomes the 1 st predetermined value.
The notification unit 104 is configured to notify the user of information on the switching of the driving mode when the remaining battery capacity of the mobile terminal 300 in use is equal to or less than a predetermined value, the vehicle is in the manual driving mode, and the mode switching control unit 122 switches from the manual driving mode to the automatic driving mode. The notification unit 104 notifies the user of information on switching of the driving mode by an image and/or a sound through a display unit (display device) and/or a sound output unit (microphone), not shown.
The central control unit 101 is incorporated in the in-vehicle device 100, is configured by a CPU or the like, and performs communication with the driving mode switching unit 200 of the vehicle while controlling each unit of the in-vehicle device 100 according to a stored program.
Next, the operation of the driving control device according to embodiment 1 of the present invention will be described with reference to fig. 2.
Fig. 2 is an operation flowchart of the driving control device according to embodiment 1 of the present invention.
The following description will be mainly made for the operation in the following case: since the user wants to listen to music while driving in the automatic driving mode or the manual driving mode on a predetermined driving route having an automatic drivable section, the mobile phone of the portable terminal 300 is wirelessly connected to the in-vehicle apparatus 100, and the music played by the portable terminal 300 is outputted through a speaker of the in-vehicle apparatus.
First, the connection section 102 of the in-vehicle apparatus 100 detects whether the portable terminal 300 is connected to the in-vehicle apparatus 100. (step S21)
When the connection unit 102 detects that the in-vehicle device 100 is connected to the mobile terminal 300 (step S21: YES), the remaining power detection unit 103 detects the remaining power of the battery of the mobile terminal 300 (step S22). Specifically, the central control unit 101 may read the data of the remaining battery capacity of the portable terminal 300 from the portable terminal 300 by communication through the connection unit 102 and transmit the data to the remaining battery capacity detection unit 103, or the remaining battery capacity detection unit 103 may read the data of the remaining battery capacity of the portable terminal 300 directly through the connection unit 102.
Next, the remaining power detection unit 103 determines whether the detected remaining battery power of the mobile terminal 300 is equal to or less than a 1 st predetermined value, for example, equal to or less than 10% of the battery power (step S23).
When the remaining power detection unit 103 detects that the remaining battery power of the portable terminal 300 is equal to or less than the 1 st predetermined value (yes in step S23), the driving mode detection unit 121 detects the current driving mode of the vehicle from the driving mode switching unit 200 of the vehicle (step S24).
The driving mode detection unit 121 determines whether or not the detected driving mode is the manual driving mode (step S25).
When it is detected that the remaining battery capacity of the portable terminal 300 is not less than the 1 st predetermined value (step S23: NO), the process returns to step S21, and the connection state of the portable terminal 300 and the remaining battery capacity are repeatedly detected at predetermined time intervals until the remaining battery capacity is detected to be less than the 1 st predetermined value.
When the driving mode detection unit 121 determines that the current driving mode is the manual driving mode (yes in step S25), the mode switching control unit 122 switches the current driving mode from the manual driving mode to the automatic driving mode (step S26). Although not shown in fig. 2, the mode switching control unit 122 may switch the current mode to the automatic driving mode and may notify the user of information that urges the user to charge the mobile terminal 300 and the switching of the driving mode by the notification unit 104 of the in-vehicle device 100. For example, as shown in fig. 3, on the display screen of the in-vehicle device 100, "switching of the automatic driving mode is now performed, and a request to charge the cellular phone is made. "the remaining power of the mobile terminal 300 equal to or lower than the 1 st predetermined value may also be displayed on the display screen in a red character or a blinking character (see the upper right of the display screen in fig. 3).
The user viewing the display may stop the manual driving, set the portable terminal 300 and the in-vehicle device 100 to be charged with the USB connection line, or charge the portable terminal 300 with a dedicated in-vehicle charger.
After the remaining charge amount detection unit 103 detects the start of charging the mobile terminal 300, the mode switching control unit 122 may switch the automatic driving mode back to the manual driving mode, and the notification unit 104 may notify the user of the switching information. When the in-vehicle device 100 charges the portable terminal 300 through the connection unit 102 via the USB connection line, the central control unit 101 may detect the start of charging.
Alternatively, the remaining battery level of the mobile terminal 300 may be detected by the remaining battery level detecting unit 103 every time a predetermined time interval elapses, and if the remaining battery level of the mobile terminal 300 detected based on the detection is equal to or higher than the 2 nd predetermined value, for example, if the remaining battery level is equal to or higher than the amount of power that can be consumed to reach the destination or equal to or higher than 50% of the remaining battery level, the mode switching control unit 122 may switch the automatic driving mode back to the manual driving mode, and the notification unit 104 may notify the user of the switching information.
In addition, when it is determined that the current driving mode is not the manual driving mode (no in step S25), the notification unit 104 may notify the user of the information that charging is necessary.
In the above-described embodiment 1, when the vehicle is traveling in the automated drivable range in which the vehicle can be driven in the automated mode, and when the automated drivable range and the manual driving range in which the vehicle needs to be driven in the manual mode are both present on the travel route, it may be detected whether or not the current travel position is in the automated drivable range before the manual driving mode is switched to the automated driving mode in step S26, and the switching from the manual driving mode to the automated driving mode may be performed only when the current travel position is in the automated drivable range.
Next, embodiment 2 of the driving control device according to the present invention will be described with reference to fig. 4, 5, 6, and 7.
Fig. 4 is a block diagram showing the configuration of a driving control apparatus according to embodiment 2 of the present invention. The in-vehicle device 100A mounted on the driving control device 10A according to embodiment 2 of the present invention is an in-vehicle navigation device.
As shown in fig. 4, the car navigation device 100A of the driving control device 10A according to embodiment 2 of the present invention is composed of a central control unit 101, a connection unit 102, a remaining power detection unit 103, a notification unit 104, a map data storage unit 105, a current position detection unit 106, a destination setting unit 107, a route search unit 108, a remaining power prediction unit 109, a charge promotion unit 110, a driving mode detection unit 121, a mode switching control unit 122, and the like. The central control unit 101, the connection unit 102, the remaining power detection unit 103, the notification unit 104, the driving mode detection unit 121, the mode switching control unit 122, and the driving mode switching unit 200 are the same as those of the driving control device according to embodiment 1, and therefore, the description thereof will be omitted here.
The map data storage unit 105 is configured by an optical disk such as a DVD or CD, a hard disk, a semiconductor memory, or the like, and stores road information such as a road name and a road LINK (LINK), and address data stored in association with an address and a location coordinate. In addition, the information includes information on an automatic drivable section in which automatic driving is possible and a manual drivable section in which automatic driving is not possible on each road. For example, as shown in fig. 6, information of an automatically drivable section cd existing on the predetermined travel road OR and an automatically drivable non-drivable manual driving section other than the automatically drivable section cd are also stored.
The current position detection unit 106 detects the current position, and calculates the current position from a plurality of GPS satellite signals (positioning data), calculates the position of the vehicle (according to autonomous navigation) using a vehicle speed sensor or a gyro sensor, or calculates the current position using a position information transmission service of a mobile phone, or a combination of these methods.
The destination setting unit 107 is a portion for setting a destination desired by the user, and is set based on an operation unit such as an operation key operated by the user, a remote controller capable of remote control, or a touch panel arranged to overlap with a screen of a display unit (not shown).
The route searching unit 108 searches for a guidance route from the current position to the destination using the map data stored in the map data storage unit 105 after the user sets the destination by the destination setting unit 107 and the current position of the vehicle is detected by the current position detecting unit 106. The route searching unit 108 then determines whether or not the searched guidance route, that is, the route from the current position to the destination on the planned travel route includes both the automatic driving enabled section and the manual driving section.
When the route searching unit 108 detects that the planned travel route includes the automatic drivable section and the manual drivable section, the remaining energy predicting unit 109 predicts whether or not the travel point of the own vehicle at which the battery remaining energy of the mobile terminal 300 becomes equal to or less than the 1 st predetermined value is located in the manual drivable section during the planned travel route.
The charging promotion unit 110 outputs the following output through a display unit (display device) and/or an audio output unit (speaker), not shown. That is, the remaining energy predicting unit 109 predicts that, when the travel point when the battery remaining energy becomes the 1 st predetermined value or less is the manual travel section and the travel-enabled automatic travel section is scheduled before the manual travel section is traveled, the user is urged to charge the automatic travel section with a display screen or a sound before entering the manual travel section.
Next, the operation of the driving control device according to embodiment 2 of the present invention will be described with reference to fig. 5.
Fig. 5 is an operation flowchart of the driving control device according to embodiment 2 of the present invention.
In embodiment 2, as a premise, a user sets a destination by the destination setting unit 107, detects a current position by the current position detecting unit 106, and searches for a guidance route from the current position to the destination by the route searching unit 108 based on map data stored in the map data storage unit 105. For example, as shown in fig. 6, the user sets a destination R by the destination setting unit 107, the current position detection unit 106 detects a current position O, and the route search unit 108 searches for a guide route OR. The operations of steps S310 to S306 in fig. 5 are basically the same as those of steps S21 to S26 in embodiment 1, and the description thereof will be omitted here.
Next, the operations in step S311 to step S317 will be described. First, the connection unit 102 of the in-vehicle device 100A detects whether or not the portable terminal 300 and the in-vehicle device 100A are in a connected state (step S311). When the connection unit 102 detects that the in-vehicle device 100A and the mobile terminal 300 are connected (yes in step S311), the central control unit 101 determines whether or not the own vehicle is traveling along the guidance route searched by the route search unit 108, that is, the scheduled travel route (step S312).
When the central control unit 101 determines that the vehicle is traveling along the planned travel route (yes in step S312), the route search unit 108 determines whether or not there is an autopilot-enabled section on the planned travel route from the current position to the destination (step S313). When determining that the route is within the autopilot section on the route (step S313: yes), the route search unit 108 further determines whether or not there is a manual section on the predetermined travel route from the current position to the destination (step S314). When it is determined that the scheduled travel road includes not only the automated driving-enabled section but also the manual driving section (yes in step S314), the remaining power predicting part 109 predicts whether or not the travel point where the vehicle travels when the battery remaining power of the portable terminal 300 becomes the 1 st predetermined value during traveling the scheduled travel road is in the manual driving section (step S315). Specifically, as shown in fig. 6, when the own vehicle travels along the scheduled travel road OR, the route searching unit 108 determines that the manual drive sections Oc and dR other than the automatic drive sections cd and cd are included in the travel road from the current position O of the own vehicle to the destination R based on the drive section data in the road data stored in the map data storage unit 105, and the remaining power predicting unit 109 calculates the travel time of the own vehicle in each travel section based on the previously set travel speed of the manual drive of the own vehicle in the manual drive section, the speed of the automatic drive travel in the automatic drive section, and the distances of the manual drive section Oc, the automatic drive section cd, and the manual drive section dR from the current position O to the destination R. Then, based on the current remaining battery capacity and the power consumption amount per unit time of the portable terminal 300, it is predicted whether or not the travel point at which the remaining battery capacity of the portable terminal 300 becomes the 1 st prescribed value during the travel of the own vehicle on the predetermined route is located in the manual drive section (Oc or dR). On the other hand, if it is determined that the vehicle is not traveling along the predetermined travel route or if it is determined that there is no autopilot section on the predetermined travel route (step S312: NO or step S313: NO), the process is ended. If the scheduled travel route does not include the manual travel route, that is, if only the automatic driving section exists (no in step S314), the process proceeds to step S302, where the remaining power detection unit 103 detects that the power of the mobile terminal 300 is the remaining power, and then the process proceeds to step S303 and subsequent steps described in embodiment 1.
Then, when the remaining energy predicting unit 109 predicts that the vehicle is located in the manual driving section at the travel point when the battery remaining energy of the mobile terminal 300 becomes the 1 st predetermined value on the planned travel road (yes in step S315), the charge promoting unit 110 determines whether or not the autonomous driving capable section will be traveled before the travel of the manual driving section (step S316). If it is determined that the user is expected to travel the automated drivable range before the manual driving range (step S316: YES), the charging promotion unit 110 prompts the user on a screen or by voice to charge the mobile terminal 300 in the automated drivable range before the manual driving range (step S317). For example, when the remaining energy predicting unit 109 predicts that the remaining battery energy of the mobile terminal 300 connected to the car navigation device 100A will become the 1 st predetermined value 10% or less when the vehicle is traveling in the non-automatically drivable section, i.e., the manual driving section dR, which is located in front of the current position O, and when the charge urging unit 110 determines that the automatically drivable section cd is present before the manual driving section dR, the charge urging unit urges the user to "the cell phone energy will be less than 10% when traveling in the non-automatically drivable section in front" on the display screen as shown in fig. 7, and thus please charge in the automatically drivable section. ". The user may also be prompted by voice. Further, as the timing of the urging, it is preferable to ensure that the user has enough time to perform the charging operation in the automated driving available section cd after the urging when the automated driving section cd before the manual driving section dR is driven.
If it is predicted that the travel position at which the battery remaining amount of the mobile terminal 300 becomes the 1 st predetermined value during the travel of the host vehicle on the scheduled route is not in the manual drive section (no in step S315), or if the autonomous drive-capable section is not traveled before the travel of the manual drive section (no in step S316), the process ends.
While the preferred embodiments of the present invention have been described above, various modifications may be made to the above embodiments without departing from the technical scope of the present invention.
