Description

[0001] Divisional Application Instructions

[0002] This application is a divisional application of the Chinese invention patent application with the application date of September 27, 2018, the invention name of which is "Vehicle status prompt system, vehicle, terminal device and vehicle status prompt method" and the application number is 2018111340170. Technical Field

[0003] The present invention relates to a vehicle status prompting system, a vehicle, a terminal device and a vehicle status prompting method for communicating with a vehicle to notify the vehicle status. Background Art

[0004] There are technologies for notifying users of a specified state of a vehicle. For example, there is a technology that, when a user leaves a vehicle with the doors unlocked and a specified distance or a specified time has passed, a sound is output from a speaker installed in the vehicle, or a call or email is sent to the user's mobile terminal to notify the user (see Japanese Patent Application Laid-Open No. 2005-344335 and Japanese Patent Application Laid-Open No. 2010-205063). As described above, the user can notice that he has forgotten to lock the doors, and can take measures such as returning to the vehicle to lock the doors. Summary of the invention

[0005] If the user gets out of the vehicle while the doors are unlocked or the lights are on, and leaves the above state, it is possible that others may get on the vehicle or the battery charge level may decrease, which is not preferred. Preferably, when the user leaves the vehicle, the vehicle is in a state such as the engine is stopped and the ignition switch is turned off, with all lights off, windows closed, and doors closed and locked. If the above state is notified by a voice from a speaker installed in the vehicle or by a visual notification through lights, display devices, etc., it will be noticed by others, and there is room for improvement in safety. In the case of notification by making a call or sending an email to the user's mobile terminal, the user may not notice it.

[0006] The present invention provides a vehicle status prompting system, a vehicle, a terminal device and a vehicle status prompting method, which can indicate that the vehicle status is not in a specified state when the user leaves the vehicle with a notification that only the user can easily notice.

[0007] The vehicle status notification system involved in the first aspect of the present invention includes: a terminal device including an ear-worn part worn on the ear of a user; and a vehicle that wirelessly communicates with the terminal device. The vehicle has: a first communication unit that communicates with the terminal device through wireless communication; and a first control unit that monitors the state of the vehicle and causes the first communication unit to send a notification signal to the terminal device, wherein the notification signal indicates that the vehicle is detected to be in a state other than a specified state. The terminal device includes: a second communication unit that communicates with the vehicle through wireless communication; an output unit that is provided on the ear-worn part and notifies the user through sound or vibration; and a second control unit that causes the output unit to perform notification to the user based on the notification signal received by the second communication unit when the terminal device moves outside a specified distance range including the vehicle.

[0008] According to the first aspect of the present invention, it is possible to notify the user only that the vehicle state is not in the predetermined state through sound or the like from the output unit worn on the ear.

[0009] In the first embodiment of the present invention, the second control unit of the terminal device may also include a determination unit, which determines that the terminal device has moved outside a specified distance range including the vehicle when the second communication unit cannot receive communication radio waves from the vehicle or when the intensity of the received communication radio waves is below a specified value.

[0010] According to the first aspect of the present invention, it is possible to detect that a user wearing a terminal device has left a vehicle based only on communication radio waves without providing any other means.

[0011] In the first aspect of the present invention, the second control unit of the terminal device may cause the output unit to perform notification to the user in accordance with the notification signal when determining that the state of the vehicle is in a first state other than a predetermined state based on the notification signal received by the second communication unit.

[0012] According to the first aspect of the present invention, when the state of the vehicle is not in a predetermined state, the user can be notified of the situation.

[0013] In the first embodiment of the present invention, the terminal device may also have an input unit that can receive a first input from a user for instructing the vehicle to be in a specified state. After the output unit executes a notification corresponding to the notification signal, when the input unit receives the first input from a user wearing the terminal device and located within a range capable of communicating with the vehicle, the second control unit causes the second communication unit to send a first indication signal to the vehicle. When the first communication unit receives the first indication signal, the first control unit of the vehicle executes an action to put the vehicle in a specified state.

[0014] According to the first aspect of the present invention, even if the user does not return to the vehicle, the vehicle can be placed in a predetermined state by remote operation, thereby improving convenience.

[0015] In the first aspect of the present invention, when the vehicle continues to be in a first state other than a predetermined state for a predetermined period after the notification signal is transmitted, the first control unit of the vehicle may execute an operation to put the vehicle in the predetermined state.

[0016] According to the first aspect of the present invention, since the vehicle can be placed in a predetermined state even without the user taking any action, convenience can be improved.

[0017] In the first mode of the present invention, the input unit of the terminal device can also receive a second input from the user for instructing the vehicle to maintain the current state. After the output unit executes the notification corresponding to the notification signal, when the input unit receives the second input from the user wearing the terminal device and located within the range capable of communicating with the vehicle, the second control unit causes the second communication unit to send the second indication signal to the vehicle. Within a specified period after the first communication unit sends the notification signal, if the first communication unit does not receive the second indication signal and the vehicle continues to be in a state other than the specified state, the first control unit of the vehicle executes an action to put the vehicle in the specified state. If the first communication unit receives the second indication signal, the first control unit of the vehicle does not execute the action to put the vehicle in the specified state.

[0018] According to the first aspect of the present invention, when the user intentionally leaves the vehicle with the vehicle in a state other than the predetermined state, the vehicle is maintained in a state other than the predetermined state by performing an operation in accordance with the intention, thereby improving convenience.

[0019] A vehicle according to a second aspect of the present invention performs wireless communication with a terminal device. The vehicle has a communication unit that communicates with the terminal device through wireless communication, the terminal device includes an ear-worn unit, the ear-worn unit is provided with an output unit for notifying the user, the output unit has a speaker worn on the user's ear; and a control unit that monitors the state of the vehicle and causes the communication unit to send a notification signal to the terminal device, wherein the notification signal indicates that the vehicle is detected to be in a state other than a prescribed state.

[0020] According to the second aspect of the present invention, the terminal device that has received the notification signal can notify the user only that the vehicle state is not in a predetermined state through sound or the like from the output unit worn on the ear.

[0021] The terminal device involved in the third embodiment of the present invention comprises: an ear-worn part, which is worn on the ear of the user; a communication part, which communicates with the vehicle through wireless communication; an output part, which is arranged on the ear-worn part and notifies the user through sound or vibration; and a control part, which, when the terminal device moves out of a specified distance range including the vehicle, causes the output part to notify the user based on a notification signal indicating the status of the vehicle received by the communication part from the vehicle.

[0022] According to the third aspect of the present invention, it is possible to notify the user only that the vehicle state is not in the predetermined state through sound or the like from the output unit worn on the ear.

[0023] The vehicle status prompt method involved in the fourth embodiment of the present invention includes: a first control step, in which the vehicle's computer monitors the status of the vehicle and sends a notification signal indicating that the vehicle is detected to be in a state other than a specified state to a terminal device via wireless communication, and the terminal device includes an ear-worn part, which is worn on the user's ear and is provided with an output part for notifying the user through sound or vibration; and a second control step, in which, when the terminal device moves outside a specified distance range including the vehicle, the computer of the terminal device causes the output part to execute notification to the user based on the notification signal received from the vehicle via the wireless communication.

[0024] According to the fourth aspect of the present invention, it is possible to notify the user only that the vehicle state is not in the predetermined state through sound or the like from the output unit worn on the ear.

[0025] According to the method of the present invention, a vehicle status prompt system can be provided, which notifies the user through sound or the like from an output unit worn on the ear when the user leaves the vehicle when the vehicle is not in a specified state, thereby making it possible to provide a notification that is difficult for others to notice but easy for the user to notice.

[0033] (summary)

[0034] The vehicle state notification system according to the first to fourth embodiments of the present invention notifies the user who has left the vehicle that the vehicle state is not in a predetermined state through sound or the like from an output unit worn on the user's ear. Therefore, the notification can be made in a manner that is easy for the user to notice but difficult for others to notice.

[0035] (First embodiment)

[0036] Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.

[0037] <Structure>

[0038] Figure 1 2 is a functional block diagram of a vehicle state notification system 11 according to the present embodiment. The vehicle state notification system 11 includes a terminal device 110 and a vehicle 210 .

[0039] The vehicle 210 includes a first control unit 211 and a first communication unit 212. The first control unit 211 controls the first communication unit 212 to perform wireless communication with the terminal device 110. When the distance between the vehicle 210 and the terminal device 110 is within the distance where wireless communication is possible, the first control unit 211 executes a communication sequence for authenticating with the terminal device 110. For example, the first control unit 211 causes the first communication unit 212 to periodically send a signal, and compares the identifier of the terminal device 110 sent in response to the signal by the terminal device 110 that has entered the distance where wireless communication is possible with the identifier of the official terminal device that has been previously associated with the vehicle, thereby authenticating the terminal device 110. After authentication, the first control unit 211 still periodically communicates with the terminal device 110 while the terminal device 110 is within the distance where communication is possible, and detects whether the terminal device 110 is within the distance. The first control unit 211 can monitor the status of various devices (not shown) of the vehicle 210, and notify the terminal device 110 of the vehicle status from the first communication unit 212.

[0040] The terminal device 110 is a small device including an ear-worn portion worn on the user's ear. As an example, the terminal device 110 includes a second control unit 111, a second communication unit 112, an output unit 113, and an input unit 114. The output unit 113 includes a speaker capable of playing sound to the user's external auditory canal (hereinafter referred to as "ear cavity"). The input unit 114 includes an authentication sound collector that collects echoes in the user's ear cavity and a speech sound collector that collects the user's speech sound. As an example, the second control unit 111 causes the output unit 113 to play authentication sound to the user's ear cavity, causes the authentication sound collector of the input unit 114 to obtain the echo of the authentication sound, and compares the characteristics of the echo with the characteristics of the echo of the formal user who has logged in in advance, thereby authenticating the user. The second control unit 111 controls the second communication unit 112 to perform the above-mentioned wireless communication with the vehicle 210. The second control unit 111 can obtain the status of the vehicle 210 based on the communication result. The second control unit 111 can generate the notification content for the user as a voice and output it to the output unit 113. The second control unit 111 may include a determination unit that monitors the state of the communication radio wave received by the second communication unit 112 from the vehicle 210.

[0041] As described above, if the terminal device 110 can authenticate the user and the vehicle 210 can authenticate the terminal device 110, the combination of the vehicle and the official user of the vehicle can be guaranteed, which is preferred. The above authentication method is only an example and can be modified. For example, the second control unit 111 of the terminal device 110 can also obtain the identifier of the vehicle 210 through communication and authenticate the vehicle based on the identifier. Figure 2 2 shows an example of a range 500 in which the vehicle 210 and the terminal device 110 can wirelessly communicate with each other. The range 500 is, for example, a range of about 10 m or less from the vehicle.

[0042] <Processing>

[0043] Figure 3 2 is a sequence diagram for explaining the processing of the terminal device 110 and the vehicle 210. Figure 3 This process is described.

[0044] Step S101: The first control unit 211 of the vehicle 210 monitors the status of various devices based on information from various control units mounted on the vehicle, for example. In this step, the first control unit 211 detects whether the status of the vehicle is not in a prescribed state. The prescribed state refers to a state in which the possibility of problems in terms of safety and power consumption is lower than that of other states even if the user leaves the vehicle and leaves it alone. As an example, the prescribed state can be defined as a state in which all lights are off, all windows are closed, and all doors are closed and locked when the engine is stopped and the ignition switch is turned off.

[0045] Step S102: If the first control unit 211 of the vehicle 210 detects that the state of the vehicle 210 is in a state other than the prescribed state, the first communication unit 212 sends a signal indicating the above situation, i.e., a notification signal. The second communication unit 112 of the terminal device 110 receives the notification signal. The notification signal contains information indicating the state of the vehicle 210, such as the window being kept open. The transmission of the notification signal as described above can be performed as part of the above-mentioned periodic communication, or can be performed separately outside the periodic communication. The notification signal can also be sent periodically while the vehicle is continuously in a state other than the prescribed state, and the transmission is stopped if the state of the vehicle becomes the prescribed state. Alternatively, the notification signal can be sent only once when it is detected that the vehicle is in a state other than the prescribed state, and a signal indicating the situation can be sent if the state of the vehicle becomes the prescribed state. Alternatively, the information indicating the current state can be sent regardless of whether the state of the vehicle 210 is in the prescribed state. By setting as described above, the terminal device 110 can obtain information indicating the state of the vehicle 210 as long as it exists within the distance where it can communicate with the vehicle 210.

[0046] Step S103: The first control unit 211 of the vehicle 210 causes the first communication unit 212 to transmit a wireless signal as a part of the above-mentioned periodic communication.

[0047] Step S104: As an example, the second control unit 111 of the terminal device 110 includes a determination unit that monitors the state of the communication radio wave from the vehicle 210. If the determination unit detects that the state of the communication radio wave has become a specified state, the second control unit 111 determines that the terminal device 110 has moved outside the specified distance range including the vehicle 210. For example, a situation where the radio wave strength of the communication radio wave becomes below a specified value can also be detected as a specified state of the communication radio wave. Alternatively, a situation where the communication radio wave cannot be received even after a certain period of standby can also be detected as a specified state of the communication radio wave. By providing the determination unit as described above, it is possible to detect that the user wearing the terminal device 110 has left the vehicle 210 using only the communication radio wave without the need for other components. However, other components can also be used for detection.

[0048] Step S105: The second control unit 111 of the terminal device 110 causes the output unit 113 to perform a notification to the user based on the received notification signal. For example, when the second control unit 111 determines that the state of the vehicle 210 is outside the specified state based on the notification signal, the output unit 113 makes a notification indicating the above situation. The notification can be made, for example, by playing a voice indicating a specific state, "the window is open", to the user's ear. In addition, there are no restrictions as long as the notification is difficult for others to notice. For example, the output unit 113 may have a vibrator and make a notification through vibration. The user who receives the notification can return to the vehicle 210 and perform actions such as closing the window to put the vehicle 210 in a specified state. With the above steps, this sequence ends.

[0049] The terminal device 110 may be, for example, a structure in which all parts are included in an ear-worn part worn on the ear of the user, or may be configured such that at least the output unit 113 is included in the ear-worn part, and other parts are included in a portable terminal device such as a mobile phone, and the ear-worn part communicates with the portable terminal device wirelessly or by wire. It is preferred to perform user authentication by the above-mentioned echo, but it is not necessary to do so. When it is determined that the terminal device 110 has moved beyond the prescribed distance range including the vehicle 210, only a notification indicating that the state of the vehicle is not in the prescribed state is made to the user. Thereafter, when it is determined based on the radio wave strength of the communication radio wave that the terminal device 110 has returned to the prescribed distance range including the vehicle 210, the user may be notified of the specific state of "the window is in the open state". It is also possible to use only the above-mentioned notification signal as a signal indicating that the state of the vehicle is not in the prescribed state, and when it is determined that the terminal device 110 has returned to the prescribed distance range including the vehicle 210, a signal indicating the specific state is obtained by communicating with the vehicle 210. It is also possible for the user to customize which state of the vehicle 210 is the prescribed state.

[0050] <Effect>

[0051] In the first embodiment, the output unit worn on the ear can notify the user only that the state of the vehicle is not in the specified state through sound or the like. In this way, it is possible to improve safety by making it difficult for others to know the notification, while making it easy for the user to notice the notification. The notification is made only when the user wearing the terminal device leaves the specified range including the vehicle. Therefore, in the case where the user intentionally leaves the vehicle in a state other than the specified state and temporarily gets off the vehicle and is about to get on the vehicle again soon, or in the case where the user does not leave the vehicle for more than the specified distance, no notification is made, thereby reducing irritation.

[0052] (Second embodiment)

[0053] Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings.

[0054] <Structure>

[0055] Since the vehicle state notification system according to the second embodiment has the same functional framework as the vehicle state notification system 11 according to the first embodiment, the same reference numerals are given to the same or corresponding components, and the description of the same contents is omitted.

[0056] <Processing>

[0057] In the second embodiment, after step S105 in the first embodiment, an instruction from the user can be received to cause the vehicle 210 to execute an operation to enter a predetermined state.

[0058] Figure 4 2 is a sequence diagram for explaining the processing of the terminal device 110 and the vehicle 210. Since the processing of steps S101 to S105 is the same as that of the first embodiment, the description thereof will be omitted. Figure 4 The processing after step S105 is recorded in.

[0059] Step S201: After step S105, the input unit 114 of the terminal device 110 receives a first input, which is a predetermined input from the user. The first input can be performed, for example, by speaking a predetermined sentence "close the window" to the speech collector of the input unit 114. The input method is not limited to this. For example, when the input unit 114 has a motion sensor, the input can be performed by the user turning his head horizontally once.

[0060] Step S202: If the second control unit 111 of the terminal device 110 analyzes the content received by the input unit 114 and determines that it is the first input, the second communication unit 112 sends a first instruction signal corresponding thereto. In the case where the method of determining that the terminal device 110 has moved from a predetermined distance range including the vehicle 210 to the outside thereof when the radio wave intensity of the communication radio wave becomes less than a predetermined value greater than 0 is adopted in step S104, since the terminal device 110 and the vehicle 210 can communicate with each other at the position at the time of receiving the notification in step S105, the processing of steps S201 and S202 can be performed even if the user does not move from the said position. However, in the case where the method of determining that the terminal device 110 has moved from a predetermined distance range including the vehicle 210 to the outside thereof when the communication radio wave cannot be received even after a certain period of standby is adopted in step S104, since the terminal device 110 and the vehicle 210 cannot communicate with each other at the position at the time of receiving the notification in step S105, the user needs to move from the above position to the direction close to the vehicle. By the above movement, the terminal device 110 and the vehicle 210 can communicate with each other, and the authentication between the terminal device 110 and the vehicle 210 is performed again. When the user moves in the direction close to the vehicle during the input of step S201, the processing of S202 can be properly performed. Therefore, it is preferable to notify the user in advance or notify the user at the time of notification of step S105 that it is necessary to get close to the vehicle when performing the first input.

[0061] Step S203: The first communication unit 212 of the vehicle 210 receives the first instruction signal. The first control unit 211 of the vehicle 210 performs various operations such as closing the windows in accordance with the first instruction signal to bring the vehicle 210 into a predetermined state. With the above steps, this sequence ends.

[0062] <Effect>

[0063] In the second embodiment, when the user receives a notification that the vehicle is not in a specified state, the user can remotely instruct the vehicle to perform an action to change to the specified state by making a specified first input to the terminal device. Therefore, there is no need to return to the vehicle to restore the vehicle to the specified state, which can improve convenience.

[0064] (Third embodiment)

[0065] Hereinafter, a third embodiment of the present invention will be described in detail with reference to the drawings.

[0066] <Structure>

[0067] Since the vehicle state notification system according to the third embodiment has the same functional framework as the vehicle state notification system 11 according to the first embodiment, the same reference numerals are given to the same or corresponding components, and the description of the same contents is omitted.

[0068] <Processing>

[0069] In the third embodiment, when the vehicle continues to be in a state other than the predetermined state for a predetermined period after step S105 in the first embodiment, the vehicle 210 can be caused to execute an operation to change to the predetermined state.

[0070] Figure 5 2 is a sequence diagram for explaining the processing of the vehicle 210. Since the processing of steps S101 to S105 is the same as that of the first embodiment, the description thereof will be omitted. Figure 5 Step S102 and subsequent steps are described in Figure 3 The sequence shown is in parallel with the processes performed by vehicle 210 .

[0071] Step S301: After step S102, the first control unit 211 of the vehicle 210 resets the timer and then starts counting the timer.

[0072] Step S302: The first control unit 211 of the vehicle 210 detects that a predetermined period has passed when the count value reaches a predetermined value. In this step, it is assumed that the first control unit 211 does not detect a change in the vehicle state within the predetermined period, that is, the vehicle continues to be in a state other than the predetermined state.

[0073] Step S303: The first control unit 211 of the vehicle 210 performs actions such as closing the windows of the vehicle 210 to bring the vehicle 210 to a prescribed state. The above steps complete the sequence. In step S302, if the vehicle's state changes within a prescribed period and becomes a prescribed state, as the user operates the vehicle to change it to the prescribed state, step S303 of the sequence is not executed. In step S302, if the vehicle's state changes within a prescribed period and becomes a state other than the prescribed state, as the user operates the vehicle to intentionally change it to a state other than the prescribed state, step S303 of the sequence may not be executed, or step S303 of the sequence may be executed to change to a more appropriate prescribed state.

[0074] The second embodiment may also be incorporated into the third embodiment. That is, the vehicle 210 may immediately execute the action of changing to the prescribed state when receiving the instruction input from the user within the prescribed period, and execute the action of changing to the prescribed state after the prescribed period when not receiving the instruction input from the user within the prescribed period. It is also possible that the counting process of step S301 is not started after step S102, but in step S105, the vehicle 210 receives a signal indicating that the terminal device 110 has notified the user, and starts counting when the signal is received. Alternatively, in the periodic communication of step S103, the counting may be started when the vehicle 210 detects that the radio wave strength of the communication radio wave is reduced or the communication radio wave cannot be received. In either case, the count value can be set in such a way that a prescribed period has passed after the notification in step S105.

[0075] <Effect>

[0076] In the third embodiment, when the user does not operate the vehicle and leaves it alone for a predetermined period after receiving a notification that the vehicle is not in the predetermined state, the vehicle can be automatically changed to the predetermined state. Therefore, since the user does not need to perform any action to change the vehicle to the predetermined state, convenience can be improved.

[0077] (Fourth embodiment)

[0078] Hereinafter, a fourth embodiment of the present invention will be described in detail with reference to the drawings.

[0079] <Structure>

[0080] Since the vehicle state notification system according to the fourth embodiment has the same functional framework as the vehicle state notification system 11 according to the first embodiment, the same reference numerals are given to the same or corresponding components, and the description of the same contents is omitted.

[0081] <Processing>

[0082] In the fourth embodiment, after step S301 in the third embodiment, it is possible to receive an instruction from the user within a predetermined period to keep the vehicle in a state other than a predetermined state.

[0083] Figure 6 2 is a sequence diagram for explaining the processing of the terminal device 110 and the vehicle 210. Since the processing of steps S101 to S105 is the same as that of the first embodiment, the description thereof will be omitted. Figure 6 Records of.

[0084] Step S401 : Similar to step S301 in the third embodiment, after step S102 , the first control unit 211 of the vehicle 210 starts counting of the timer.

[0085] Step S402: In this step, it is assumed that the input unit 114 of the terminal device 110 receives a prescribed input, i.e., a second input, from the user before a prescribed period of time has passed. The second input can be performed, for example, by saying a prescribed sentence "keep it as it is" to the speech collector of the input unit 114. The input method is not limited to this. For example, in the case where the input unit 114 has a motion sensor, it can be performed by the user swinging his head sideways. Similar to the second embodiment, in step S104, when a method is adopted in which the terminal device 110 is determined to have moved from a prescribed distance range including the vehicle 210 to its outside when a communication radio wave cannot be received even after a certain period of standby, the user moves in a direction close to the vehicle before performing the second input.

[0086] Step S403: If the second control unit 111 of the terminal device 110 analyzes the content received by the input unit 114 and determines that it is the second input, the second control unit 111 of the terminal device 110 causes the second communication unit 112 to transmit a second instruction signal corresponding thereto.

[0087] Step S404: The first communication unit 212 of the vehicle 210 receives the second instruction signal. The first control unit 211 of the vehicle 210 stops counting the timer in response to the second instruction signal. As described above, when the second instruction signal is received, the first control unit 211 does not perform the action of changing the vehicle 210 to the specified state, and this sequence ends.

[0088] Step S405: In this step, it is assumed that the first communication unit 212 does not receive the second instruction signal within the prescribed period, and the first control unit 211 does not detect a change in the state of the vehicle, that is, the vehicle continues to be in a state other than the prescribed state. In this case, similar to step S302 in the third embodiment, the first control unit 211 of the vehicle 210 detects that the prescribed period has passed when the count value reaches the prescribed value.

[0089] Step S406: The first control unit 211 of the vehicle 210 executes operations of various parts such as closing windows, similarly to step S303 in the third embodiment, so that the state of the vehicle 210 becomes a predetermined state. With the above steps, this sequence ends.

[0090] The second embodiment may be incorporated into the fourth embodiment. That is, the first control unit 211 of the vehicle 210 may also cause the vehicle to immediately execute the action of changing to the specified state when receiving the instruction input from the user within the specified period. The sequence may not be terminated in step S404, but the same processing as steps S405 and S406 may be performed, and after a certain time longer than the above-mentioned specified time has passed, the first control unit 211 of the vehicle 210 executes the action of changing the vehicle to the specified state.

[0091] <Effect>

[0092] In the fourth embodiment, when the user does not operate the vehicle and leaves it alone for a prescribed period after receiving a notification that the vehicle is not in the prescribed state, the vehicle automatically enters the prescribed state, and when the user performs a prescribed second input within the prescribed period, the vehicle is prevented from automatically entering the prescribed state. Therefore, when the user intentionally leaves the vehicle in a state other than the prescribed state, the convenience can be improved by maintaining the vehicle in a state other than the prescribed state in accordance with the intention.

[0093] As described in the above embodiments, according to the present invention, a vehicle status prompt system can be provided, which can notify that the vehicle status is not in a specified state in a manner that is easy for only the user who has left the vehicle to notice. As described above, for example, when the user gradually leaves the vehicle in an inappropriate state in terms of safety or power consumption, the user can be notified without being known by others, and the user can be prompted to take appropriate measures.

[0094] The present invention is not only understood as a vehicle status prompt system, but can also be understood as a vehicle status prompt method and its program executed by a terminal device, a vehicle, and a processor of a computer contained in the terminal device and the vehicle that constitute the vehicle status prompt system.

[0095] The present invention is useful in a system for notifying a user of the status of a vehicle or the like.
