The present invention relates to a vehicle remote control system, a vehicle remote control method, a server, a terminal device, and a communication device.
As an apparatus mounted in a vehicle, PTL 1 discloses, for example, a vehicle remote control system configured to, if an abnormality of a vehicle such as detachment of a wire to a battery is detected, output a warning to a server and set the vehicle in an activation disabled state by remote control.
PTL 1: Japanese Patent No. 6238038
In the configuration of PTL 1, however, it is impossible to discriminate between a case in which the wire is detached by a theft or the like and a case in which the wire is intentionally detached by a normal maintenance work such as battery exchange. For this reason, even if the wire is intentionally detached in the normal maintenance work, and voltage information of the battery cannot be acquired, a warning may be transmitted to the server upon judging the state as a vehicle abnormality, and the vehicle may be set in a state in which it cannot be activated based on remote control of the server.
The present invention has been made in consideration of the above-described problem and provides a technique capable of suppressing transmission of a warning if a vehicle is in a maintenance state even if the voltage information of a power supply device cannot be acquired.

Further features of the present invention will become apparent from the following description of exemplary embodiments (with reference to the attached drawings).
The accompanying drawings showing the embodiments of the present invention constitute a part of the specification and, together with the description, serve to explain the present invention.
Hereinafter, embodiments will be described in detail with reference to the attached drawings. Note, the following embodiments are not intended to limit the scope of the claimed invention, and limitation is not made to an invention that requires a combination of all features described in the embodiments. Two or more of the multiple features described in the embodiments may be combined as appropriate. Furthermore, the same reference numerals are given to the same or similar configurations, and redundant description thereof is omitted.
The vehicle 1 is, for example, a straddle type vehicle in this embodiment but may be a riding type vehicle. Note that the straddle type vehicle indicates a type that a driver rides while straddling the vehicle body, and the concept includes not only a typical motorcycle (including a scooter-type vehicle) but also a three-wheeled vehicle (a vehicle with one front wheel and two rear wheels or a vehicle with two front wheels and one rear wheel), and an all terrain vehicle (ATV) such as a four-wheeled buggy.
The vehicle 1 includes a power source 11, a battery 12 (power supply device) that supplies power to the vehicle, an operation mechanism 13, a starting device 14, a control device 15 that controls the vehicle, and a communication device 16. In this embodiment, the power source 11 is an internal combustion engine (engine). However, as another embodiment, an electric motor such as a three-phase induction motor may be used as the power source 11. The battery 12 can supply power to each element of the vehicle 1. A secondary battery that can be charged based on the power of the power source 11 is used as the battery 12. Examples are a lead storage battery, a lithium ion battery, and a nickel hydrogen battery.
The operation mechanism 13 is configured to be able to input an operation for controlling the power source 11 and, for example, outputs a predetermined control signal to the control device 15 (to be described later) based on an operation input by the user A. Examples of the operation input to the operation mechanism 13 are a rotating operation using a predetermined key (an ignition key, a remote key, or the like) corresponding to the vehicle 1, and a pressing operation using a press type switch (a start switch, or the like).
Based on the operation input to the operation mechanism 13, the starting device 14 can start the power source 11 and set it in an operation state, and can also stop the power source 11 in the operation state. For the starting device 14, a known ignition device including an igniter and the like is used.
The control device 15 is an ECU (Electronic Control Unit) capable of performing operation control of the entire vehicle 1, and can, for example, transmit/receive signals to/from each constituent element of the vehicle 1 via predetermined signal lines. As an example, the control device 15 can receive a control signal according to an operation input to the operation mechanism 13 and control to cause the starting device 14 to start the power source 11.
The functions of the control device 15 can be implemented by either hardware or software. For example, the functions of the control device 15 may be implemented by executing a predetermined program by a CPU (Central Processing Unit) using a memory. Alternatively, the functions of the control device 15 may be implemented by a known semiconductor device such as a PLD (Programmable Logic Device) or an ASIC (Application Specific Integrated Circuit). The control device 15 is shown here as a single element. However, the control device 15 may be divided into two or more elements as needed.
The communication device 16 includes an antenna configured to implement communication with the server 2 via the network N, and includes a TCU (Telematics Control Unit) that performs signal processing for performing communication with the server 2 via the network N. The TCU can acquire, from the battery 12, voltage information representing the voltage value of the battery 12. Also, the TCU can acquire from the control device 15 (ECU), control information representing the control state of the vehicle 1. The TCU transmits the acquired voltage information of the battery 12 and the control information of the control device 15 (ECU) to the server 2 via the network N. In addition, the TCU can intervene in vehicle control by the control device 15 based on the information received from the server 2 and control the control device 15 to restrict the functions of the vehicle 1. Details of the processing of the TCU will be described later.
The server 2 that remote-controls the vehicle 1 includes a processing unit 21, a storage unit 22, and a communication interface unit 23 (communication I/F) and is installed in, for example, a management company that provides a vehicle use service. The processing unit 21 is formed by a processor including a CPU and a memory, and the storage unit 22 is formed by a RAM serving as the processing area of a program, a ROM that stores various programs and data, and an HDD (Hard Disk Drive) having a relatively large capacity. In addition, the storage unit 22 may be distributedly arranged on a cloud.
For example, the processing unit 21 can communicate with the vehicle 1 by the communication interface unit 23 via the network N, store information about the vehicle 1 in the storage unit 22, or read out the information about the vehicle 1 from the storage unit 22. The processing unit 21 can also communicate with the terminal device (a portable terminal device such as a smartphone) of a user A of the vehicle 1, store information about the user A in the storage unit 22, or read out the information about the user A from the storage unit 22. The information about the vehicle 1 and the information about the user A are associated with each other to form a database DB concerning the vehicle 1 and the user A. Similarly, the database DB is also formed even for each of another user B during driving and other users (not shown).
In the vehicle remote control system SY (vehicle remote control system), the server 2 of the management company can communicate with the vehicle 1, the user A, and the like and perform predetermined management. Examples of the vehicle use service are a vehicle sales service and a vehicle rental service, and examples of the management by the management company are permission of use of the vehicle 1 for a user and restriction of the functions of the vehicle 1.
The communication interface unit 23 of the server 2 receives a warning that is transmitted from the communication device 16 of the vehicle 1 and configured to notify an abnormality of the vehicle 1. The processing unit 21 generates a control signal for remote-controlling the vehicle 1 based on the received warning. Also, the communication interface unit 23 transmits the generated control signal to the vehicle (for example, the communication device 16 of the vehicle 1). The communication device 16 of the vehicle 1 outputs the information (control signal) received from the server 2 to the control device 15. Based on the information (control signal) acquired from the communication device 16, the control device 15 controls the vehicle 1 to restrict the functions of the vehicle 1. For example, if vehicle sales based on a loan contract is made between the management company and the user A, the server 2 of the management company can permit the user A to use the vehicle 1 when appropriate payment by the user A is being done, and restrict use (restrict the functions of the vehicle 1) if payment delays. As an example, the server 2 manages the state of payment by the user A on the database DB. If payment delays, as a signal (function restriction signal) for requesting function restriction of the vehicle 1, the server 2 transmits, for example, a signal for requesting to restrict starting of the power source 11 to the vehicle 1 of the user A. In the vehicle 1, in accordance with the reception of the signal from the server 2 by the communication device 16, the control device 15 can suppress starting of the power source 11 by the starting device 14.
The operation mechanism 13 can selectively output a starting signal SIG1 and a stop signal SIG2 as control signals for controlling the power source 11. The starting signal SIG1 is a control signal for starting the power source 11 in a stop state. The stop signal SIG2 is a signal for stopping the power source 11 in an operation state. For example, if an operation of instructing to start the power source 11 is input to the operation mechanism 13, the operation mechanism 13 outputs the starting signal SIG1 to the control device 15. For example, if an operation of instructing to stop the power source 11 is input to the operation mechanism 13, the operation mechanism 13 outputs the stop signal SIG2 to the control device 15.
The communication device 16 can communicate with the server 2 via the network N. Upon receiving a warning from the communication device 16 (TCU), the server 2 generates the starting restriction signal SIG3 as a control signal for restricting starting of the power source 11 based on the starting signal SIG1, and transmits the starting restriction signal SIG3 to the communication device 16 (TCU). The communication device 16 outputs the starting restriction signal SIG3 received from the server 2 to the control device 15 as a control signal for controlling the power source 11.
In addition, the TCU of the communication device 16 can acquire, from the battery 12, voltage information representing the voltage value of the battery 12. Also, the TCU can acquire, from the control device 15, control information representing the control state of the vehicle 1. The TCU transmits the acquired voltage information of the battery 12 and the control information of the control device 15 to the server 2 via the network N.
Upon receiving the notification (warning) for giving a warning from the TCU, the server 2 registers the user as a user who does not deal with maintenance in the database (DB) of the server 2 and manages the information of the user. In addition, upon receiving information from the communication device 16 (TCU), the server 2 distributes the information to a system administrator TG and a terminal device TM of the user of the vehicle 1. The notification for calling attention and the notification (warning) for giving a warning are distributed stepwise to the terminal device TM of the user concerning the maintenance work such as exchange of the battery 12.
ST2 in
The control device 15 can control the power source 11 based on the starting signal SIG1, the stop signal SIG2, or the starting restriction signal SIG3. For example, before reception of the starting restriction signal SIG3, the control device 15 starts the power source 11 in accordance with reception of the starting signal SIG1, and stops the power source 11 in accordance with reception of the stop signal SIG2. Once the starting restriction signal SIG3 is received, the control device 15 does not start the power source 11 even if the starting signal SIG1 is received. Also, if the power source 11 is in the operation state, the control device 15 does not stop the power source 11 in the operation state even if the starting restriction signal SIG3 is received, and maintains the power source 11 in the operation state until the stop signal SIG2 is received.
(Functional Configuration of TCU)
If the voltage information of the battery 12 cannot be acquired, the warning unit 310 transmits a warning for notifying the abnormality of the vehicle 1 to the server 2. The transmission of the warning to the server 2 is performed via the communication processing unit 300.
The state determination unit 320 determines whether the vehicle 1 is in the maintenance state. Whether the vehicle is in the maintenance state can be determined by, for example, determining, based on the position information of the vehicle 1, whether the vehicle 1 is located in a region (geofence) where maintenance is permitted, or based on the presence/absence of an operation input for setting the state of the vehicle 1 to the above-described from the terminal device of the user.
The state determination unit 320 can also determine whether the vehicle 1 is in the maintenance state, using the position information of the vehicle 1 and the control information that the communication processing unit 300 acquires from the control device 15 (ECU). A detailed example of the processing of the state determination unit 320 will be described later.
If the vehicle 1 is in the maintenance state, the processing suppression unit 330 suppresses processing of the warning unit 310 such that a warning is not transmitted. That is, if the state determination unit 320 determines that the vehicle 1 is in the maintenance state, the processing suppression unit 330 suppresses the processing of the warning unit 310 such that a warning is not transmitted. A geofence setting unit 340 sets a region (geofence) where maintenance is permitted on map information.
The sensor unit 350 has the function of a position detection unit configured to detect the current position of the vehicle 1, receives a GPS satellite signal by a GPS sensor, and measures the current position (a latitude and a longitude) of the vehicle 1. Note that the sensor unit 350 need not always be provided in the contents of the TCU and may be provided in the vehicle 1. The sensor unit 350 may be provided in both the TCU and the vehicle 1, and the state determination unit 320 may compare the information of the current positions (latitudes and longitudes) obtained by the sensor units 350 and compare the relative distances of these.
(Setting of Geofence)
In this embodiment, as a configuration for suppressing the processing of the warning unit 310, an example based on the result of determining whether the position information of the vehicle 1 is located in a region (geofence) where maintenance is permitted will be described. In this embodiment, the state determination unit 320 determines, based on the position information of the vehicle 1, whether the vehicle 1 is in the maintenance state.
The region where maintenance is permitted includes, for example, a dealer that sells or maintains the vehicle 1, the home of the user of the vehicle 1, and the like. The information of the region where maintenance is permitted can be downloaded by communication with the server 2 and stored in a storage unit 315. For example, based on the position information (the latitude and the longitude) of a dealer, a region within the range of a predetermined radius can be stored in the storage unit 315 as the region (geofence) where maintenance is possible.
The base of maintenance can be designated by the terminal device of the dealer or the user, and the geofence setting unit 340 sets a geofence with respect to each designated base as the center. Also, if a plurality of bases are designated as the base of a maintenance work, the geofence setting unit 340 can also set, as a combined geofence, a region formed by combining the region GE1 (geofence) and the region GE2 (geofence) with respect to each designed base as the center. Note that although
(Processing of TCU)
In step S520, the state determination unit 320 acquires the region information of the region where maintenance is permitted and the position information (the latitude and the longitude) of the vehicle 1. Here, the position information (the latitude and the longitude) of the vehicle 1 is based on the detection result of the sensor unit 350, and the state determination unit 320 acquires the position information of the vehicle 1 from the sensor unit 350.
In addition, the region information of the region (geofence) where maintenance is permitted includes the position information (the latitude and the longitude) of the maintenance work base designated in step S510 and the information of a radius R used to set a predetermined range with respect to the position information as the center. If the geofence is set by a rectangle, the region information includes the position information (the latitude and the longitude) of the base and the information of the lengths of sides that form the rectangle.
In step S530, the state determination unit 320 compares the region information of the region (geofence) with the position information (the latitude and the longitude) of the vehicle 1, and determines whether the vehicle 1 is located in the region (geofence) where maintenance is permitted.
If the vehicle 1 is not located in the region in the determination processing of step S530 (NO in step S530), in step S560, the state determination unit 320 determines that the vehicle 1 is not in the maintenance state.
Then, in step S570, the processing suppression unit 330 does not suppress the processing of the warning unit 310. In this case, if voltage information cannot be acquired from the battery 12 (power supply device), it is determined that the vehicle 1 has an abnormality, and the warning unit 310 transmits a warning for notifying the abnormality of the vehicle 1 to the server 2.
On the other hand, if the vehicle 1 is located in the region (geofence) in the determination processing of step S530 (YES in step S530), in step S540, the state determination unit 320 determines that the vehicle 1 is in the maintenance state.
Note that if the TCU and the battery 12 can be detached as a maintenance work in the region (geofence), a form of a theft (vehicle abnormality) can also be considered in which the TCU and a nongenuine battery are left in a connected state, and the vehicle 1 is taken away. In this case, in the region (geofence), the state determination unit 320 can determine that the vehicle 1 is in the maintenance state on condition that the state determination unit 320 can further acquire the control information of the control device 15 (ECU).
That is, the state determination unit 320 can acquire the region information of the region where maintenance is permitted and the position information of the vehicle 1, and determine that the vehicle 1 is in the maintenance state if the vehicle 1 is located in the region, and the control information can be acquired.
The determination processing of the state determination unit 320 may be based on comparison between the position information and the region information of the region (geofence), or a condition that the control information of the control device 15 (ECU) can be acquired may be combined.
Then, in step S550, the processing suppression unit 330 suppresses the processing of the warning unit 310 such that a warning is not transmitted. In this case, even if voltage information from the battery 12 (power supply device) or control information from the control device 15 cannot be acquired, it is not determined that the vehicle 1 has an abnormality, and the processing suppression unit 330 suppresses the processing of the warning unit 310 such that a warning is not transmitted.
Note that the state determination unit 320 can determine whether a maintenance work is normal. For example, if voltage information acquired from the battery 12 (power supply device) after the end of maintenance is equal to or less than a voltage value serving as a reference, the state determination unit 320 determines that the maintenance work is not normal, and the warning unit 310 transmits a warning to the server 2 even if the vehicle 1 is located in the region (geofence).
For example, if the battery is exchanged with the genuine battery 12, the initial voltage value is the voltage value V1, as shown in ST1 of
Alternatively, the state determination unit 320 further acquires identification information from the battery 12 (power supply device) after the end of maintenance. If the acquired identification information is different from authentic identification information, the state determination unit 320 determines that the maintenance work is not normal. In this case, the warning unit 310 transmits a warning to the server 2 even if the vehicle 1 is located in the region (geofence). Even in the geofence, if the voltage value is 0 after the elapse of a predetermined time, the warning unit 310 transmits a warning to the server 2. This makes it possible to prevent battery attachment from being forgotten or prevent the battery in the TCU from being exhausted due to long-time detachment of the battery.
According to this embodiment, even if the voltage information of the power supply device cannot be acquired, transmission of a warning can be suppressed if the vehicle is in the maintenance state. Hence, if the straddle type vehicle is in the maintenance state, the user can perform a maintenance work without issuance of a warning.
In this embodiment, a configuration will be described in which processing of a warning unit 310 is suppressed based on an operation input for setting the state of a vehicle 1 in a maintenance state from the terminal device of a user. The configuration of a vehicle remote control system SY is the same as in the first embodiment, and constituent elements will be described by adding the same reference numerals to the same or similar components. Also, in this embodiment, based on the presence/absence of an operation input from an operation portion 610 (
(Processing of TCU)
If T1 (for example, 5 min) is input as the extended time by the user operation, the extended time setting portion 630 can set, as the extended time, time T2 (=T1+α: for example, 7 min) obtained by adding an extra time α (for example, 2 min) to the extended time T1 input by the user operation. This makes it possible to set a maintenance time longer than the maintenance time assumed by the user and suppress transmission of a warning within the extended time including the added extra time α. The user can perform a maintenance work without issuance of a warning within the extended time including the added extra time.
A remaining maintenance time is displayed in a remaining time display portion 640 of the terminal device 600. For example, when the user operates the operation portion 610 (maintenance state setting button), a time counted down from a predetermined time set as the maintenance time is displayed as the remaining time. Similarly, when the user operates the extension operation portion 620 (extension setting button) or the extended time setting portion 630, a time counted down from the extended time is displayed as the remaining time. Processing of the operation portion 610, the extension operation portion 620, and the extended time setting portion 630 and display control of the remaining time display portion 640 can be performed by the CPU of the terminal device 600. The CPU of the terminal device 600 can perform not only communication with a server 2 but also communication with a communication device 16. If the user confirms the display on the remaining time display portion 640 and confirms that the maintenance work does not end within a predetermined time, the maintenance time can be extended by operating the extension operation portion 620.
Then, in step S750, the processing suppression unit 330 does not suppress the processing of the warning unit 310. In this case, if voltage information cannot be acquired from the battery 12 (power supply device), it is determined that the vehicle 1 has an abnormality, and the warning unit 310 transmits a warning for notifying the abnormality of the vehicle 1 to the server 2.
On the other hand, if an operation input from the operation portion 610 is present in the determination processing of step S710 (YES in step S710), in step S720, the state determination unit 320 determines that the vehicle 1 is in the maintenance state.
Then, in step S730, the processing suppression unit 330 suppresses the processing of the warning unit 310 until a predetermined time elapses from the operation input. In this case, even if voltage information from the battery 12 (power supply device) or control information from a control device 15 cannot be acquired during the time until the predetermined time elapses, it is not determined that the vehicle 1 has an abnormality, and the processing suppression unit 330 suppresses the processing of the warning unit 310 such that a warning is not transmitted.
Here, in the determination processing of step S710, the state determination unit 320 may count the number of times of operation inputs from the operation portion 610 during a predetermined period. If the number of times of operation inputs exceeds a count limit serving as a reference, the warning unit 310 can transmit a warning for notifying the abnormality of the vehicle 1 to the server 2.
Also, in step S730, if an operation of setting extension of a predetermined time is input from the extension operation portion 620, the processing suppression unit 330 can set the extended time extended by the predetermined time and suppress the processing of the warning unit 310 until the extended time elapses.
In addition, the state determination unit 320 can determine whether a maintenance work is normal. For example, if voltage information acquired from the battery 12 (power supply device) after the elapse of a predetermined time is equal to or less than a voltage value serving as a reference, the state determination unit 320 determines that the maintenance work is not normal, and the warning unit 310 transmits a warning to the server 2.
Alternatively, the state determination unit 320 further acquires identification information from the battery 12 (power supply device) after the elapse of a predetermined time. If the acquired identification information is different from authentic identification information, the state determination unit 320 determines that the maintenance work is not normal, and the warning unit 310 transmits a warning to the server 2.
According to this embodiment, even if the voltage information of the power supply device cannot be acquired, transmission of a warning can be suppressed if the vehicle is in the maintenance state. Hence, if the straddle type vehicle is in the maintenance state, the user can perform a maintenance work without issuance of a warning.
In the above description, the elements are represented by names associated with their functions to facilitate understanding. However, the elements are not limited to those having the contents described in the embodiments as the main functions and may auxiliarily have the functions. For example, although the straddle type vehicle 1 has been described as a typical example in the embodiments, the contents of the embodiments can be applied to a variety of vehicles.
