JP 2006-063650 A

  However, in the conventional technology, the user can close the window of the vehicle from a remote location, but in a remote location, the weather may be different between the location where the user is and the parking location of the vehicle. It may not be possible to close the window even if it rains in the parking area. For example, hiking courses often restrict the entry of vehicles to the surroundings in order to protect the natural environment. For this reason, the vehicle is parked at a parking place relatively far from the hiking course. In such a case, it is quite possible that the hiking trail is sunny, but it is raining at the parking place.

  Against the background of the above problems, an object of the present invention is to provide a vehicle rain countermeasure device that can close a window even if it is raining at a vehicle parking place where the weather is different between the user's place and the vehicle parking place.

  If there is an occupant in the vehicle, the occupant may be talking through the window or may be sleeping. In this situation, if the window suddenly closes even though the occupant is not operating, the occupant will be surprised. With the above configuration, it is possible to prevent the convenience of the user or the passenger from being impaired by closing the power window only when necessary. Also, if the occupant determines that the rain falls into the passenger compartment, he will close the power window himself, and he may want to keep the power window open even if the rain falls into the passenger compartment. You can also prioritize your will.

  Moreover, the rain prevention device for a vehicle according to the present invention includes a portable terminal carried by the user of the own vehicle, and when the power window is closed, information on the closed state is transmitted to the portable terminal via the center. It is comprised so that the window state information output means to output may be provided.

  With the above configuration, the user of the host vehicle can grasp that it is raining in the vicinity of the parking place of the host vehicle, so that the power window of the host vehicle is closed and rain does not fall into the vehicle interior. So that you don't have to worry about it.

  Further, the host vehicle in the vehicle rain countermeasure device of the present invention includes receiving means for receiving a remote signal from the portable terminal through the center, and the opening / closing drive control means opens the power window to the remote signal. When the content signal is included, the open / close driving means is controlled to open the power window.

  For example, the power window is sometimes opened narrowly for ventilation or to prevent the temperature inside the vehicle from rising in summer. At this time, it is not necessary to close the window if the vehicle is parked in a place where there is no worry about rain, such as an indoor parking lot. With the above configuration, the user's intention can be prioritized, and the window of the host vehicle once closed by the user can be returned to the open state.

  Further, the vehicle rain prevention device of the present invention includes a window state detecting means for detecting an open position of the power window, and an open position of the power window before the power window is changed from the open state to the closed state by the opening / closing drive control means.

  The portable terminal 3 may be any of a cellular phone, a PDA (Personal Data Assistant: portable information terminal), or a notebook PC.

  As shown in FIG. 1, a server device 51 is installed in the center 5. The server device 51 is configured as a known personal computer or workstation. In the server device 51, a DB 52 as a database is constructed on a storage medium such as a hard disk device (HDD, not shown).

  The outline of the present invention will be described with reference to the sequence diagram of FIG. First, when the vehicle 2 is traveling, the rain level of the rain sensor 201 (rainfall detection state), the state of the wiper switch 202 (rainfall detection state), and the current position (position) of the vehicle 2 detected by the position detection unit 203. Information) is transmitted to the center 5 (SQ1). Moreover, you may transmit together with vehicle ID for identifying a vehicle. The vehicle ID is stored in the memory 212 in advance.

  The center 5 creates rainfall state information based on the received information. That is, when the rain level exceeds a predetermined threshold value, or when the wiper switch 202 indicates that the wiper is operating, it is determined that the rain state is present, and the current vehicle 2 currently acquired at the same time is determined. Information that the area including the location is in a rainy state is registered (updated) in the database DB52 (SQ2). The region is configured by dividing the map into a mesh shape such as 1 km square. Further, the rain state may be classified as rain or light rain based on the rain level.

  FIG. 4 shows a configuration example of the DB 52. FIG. 4 (a) shows an example of storage of rain conditions. Rain conditions are stored in association with each region. Data of a vehicle that has transmitted information (transmission vehicle) may also be stored. As shown in FIG. 4B, the DB 52 stores a vehicle ID for identifying the vehicle, a user of the vehicle, and a password in association with each other.

  Returning to FIG. 3, the center 5 transmits rainfall state information (rainfall information associated with the region) (SQ3). The rain state information can be received by both the traveling vehicle and the parked vehicle.

  The parked vehicle 2 that has received the rain state information closes the power window 223 when the rain state in the area including the current position is rain (SQ4). Subsequently, information indicating that the window has been closed is transmitted to the center 5. The center 5 relays this information and transmits it to the portable terminal 3 possessed by the user of the corresponding vehicle 2 (SQ5).

  The user who has received the window closing notification transmits to the center 5 a signal (remote signal) for canceling the window closing as necessary and returning the power window 223 to the state before the closing state. The center 5 relays the signal and transmits it to the corresponding user's vehicle (SQ6). And the vehicle which received this signal returns the power window 223 to the state before becoming a closed state.

  The information transmission process in the vehicle 2 will be described with reference to FIG. This process is included in the control program 211p and is repeatedly executed together with other processes of the control program 211p. Further, this process corresponds to the sequence SQ1 in FIG.

  First, the vehicle state is acquired from the vehicle state detection unit 205 (S11). Then, it is determined whether or not the vehicle 2 is traveling. For example, if the ignition switch is on, it is determined that the vehicle 2 is traveling. If the shift position is in the “D” range, it is determined that the vehicle 2 is traveling. If the parking brake is released and the parking brake switch is off, it is determined that the vehicle 2 is traveling. Further, it is determined that the vehicle is traveling when the vehicle speed detected by the vehicle speed sensor exceeds 5 km / h. Among these determination conditions, one or a plurality of combinations are used.

  When it is determined that the vehicle 2 is not traveling (S12: No), this process is immediately terminated. On the other hand, when it is determined that the vehicle 2 is traveling (S12: Yes), the state of the rain sensor 201 is acquired (S13). Next, the state of the wiper switch 202 is acquired (S14). Of course, for example, when the rain sensor 201 is not installed in the vehicle, step S13 is skipped.

  And it is determined whether it is a rainy state (S15). When the rain level detected by the rain sensor 201 exceeds a predetermined threshold value or when the wiper switch 202 is other than the OFF state, the rain state is determined. Further, the rainfall amount may be estimated based on the rainfall level or the position of the wiper switch 202. The rain state determination may be performed at the center 5.

  Next, the current position information of the vehicle 2 is acquired from the position detection unit 203 (S16). Then, the above-described rainfall judgment result (rainfall detection state) and current position information (position information) are transmitted to the center 5 (S17). When the rain state is determined at the center 5, the state of the rain sensor 201 and the state of the wiper switch 202 are transmitted as the rain detection state. Moreover, you may transmit together with vehicle ID for identifying the vehicle previously memorize | stored in the memory 212. FIG.

  With reference to FIG. 6, the rain state information creation processing in the server device 51 of the center 5 will be described. This process is included in an application program stored in a storage medium such as an HDD (not shown) of the server device 51, and is repeatedly executed together with other processes of the application program. This process corresponds to the sequences SQ2 and SQ3 in FIG.

  First, it is determined whether the rain detection state and the current position information are received from the vehicle 2. When these pieces of information have not been received (S31: No), this processing is immediately terminated. On the other hand, when these pieces of information are received (S31: Yes), the rain detection state and the current position information are acquired (S32), and the rain determination is performed by the same method as step S15 in FIG. 5 (S33). When the vehicle 2 is configured to perform rainfall determination and receive the result as a rain detection state, step S33 is skipped.

  Subsequently, registration / update to the database DB 52 is performed based on the rain determination result or the rain detection state and the current position information (S34). That is, as described above, the rain state of the area including the current position information among the areas divided by the 1 km square mesh is updated. Finally, the rain state information including the updated rain state (and region) is transmitted (S35).

  The window closing control process in the vehicle 2 will be described with reference to FIG. This process is included in the control program 211p and is repeatedly executed together with other processes of the control program 211p. This process corresponds to a part of the sequences SQ4, SQ5, and SQ6 in FIG.

  First, it is determined whether or not rain state information has been received from the center 5. When the rainfall state information is not received (S51: No), the process proceeds to step S60 (described later). On the other hand, when the rainfall state information is received (S51: Yes), the vehicle state is acquired from the vehicle state detection unit 205 (S52). And it is determined by the above methods whether the vehicle 2 is parked.

In addition to the method of receiving the rainfall state information from the center 5, the following method may be used.
Based on the state of the rain sensor 201 provided in the host vehicle, it is determined whether or not it is raining as in step S15 in FIG. 5, and the result is acquired as raining state information. The rain sensor 201 is intermittently operated at a predetermined timing. Thereby, battery consumption can be suppressed.
-Cars communicate with other running vehicles via the transceiver 220, receive the status of the rain sensor and wiper switch of the running vehicle, and whether or not it is raining as in step S15 in FIG. And the result is acquired as rainfall state information. In this case, if the vehicle speed information is received from another vehicle, it can be determined whether or not the vehicle is traveling.
・ Receive radio weather forecast and obtain it as rainfall condition information. Since the weather forecast is voice data, it is converted into text data using a known voice recognition unit (not shown), and a search (character string search) of the area and the weather condition (rainfall condition) is performed on the text data.
・ Acquire weather information as rain condition information from weather information sites and news sites on the Internet. Since such information can also be acquired as text data, a character string search is possible. Weather information sites deliver weather information in near real time, so it is highly accurate.

  When it is determined that the vehicle 2 is not parked (that is, traveling) (S53: No), the process proceeds to step S60 (described later). On the other hand, when it is determined that the vehicle 2 is parked (S53: Yes), the current position information of the vehicle 2 is acquired from the position detection unit 203 (S54). Then, it is checked whether or not the received rainfall state information includes information regarding the region including the current position, and it is determined whether or not the region is in a rain state (whether it includes rain information) (S55).

  When the area where the vehicle 2 is parked is not raining (S56: No), the process proceeds to step S60 (described later). On the other hand, when the area where the vehicle 2 is parked is raining (S56: Yes), the detection state of the window state detection unit 204 is acquired, and the open position of the power window 223 in the open state is set to the power window 223. The information is stored in the memory 212 in association with the position (driver's seat side, rear seat right side, etc.) (S57). A window closing process for closing the power window 223 in the open state is executed (S58, described later). Then, information indicating that the power window 223 is closed (window closing information) is transmitted to the center 5 (S59). Note that when the power window 223 is not closed at all in step S58 (when there is no open window), the window closing information need not be transmitted.

  Thereafter, it is determined whether or not window closing cancellation information is received from the center 5. Since the window closing cancellation information is mainly transmitted with the vehicle ID, it can be determined whether or not the window closing cancellation information is for the own vehicle by comparing with the vehicle ID of the own vehicle. When the window closing cancellation information is not received (S60: No), this processing is immediately terminated. On the other hand, when the window closing cancellation information is received (S60: Yes), the open position (including the position of the power window 223) of the power window 223 stored in step S57 is read from the memory 212 (S61). Then, a command is sent to the power window drive unit 221, and the corresponding power window 223 is opened so as to be a position before the window is closed (open position of the read power window 223) (S62).

  The window closing process corresponding to step S58 in FIG. 7 will be described with reference to FIG. This process is executed for all power windows (windows) that can be controlled to open and close the vehicle 2 in the order of, for example, a driver seat side window → a passenger seat side window → a rear right seat side window → a rear left seat side window. First, the open / closed state of the power window 223 is acquired from the window state detection unit 204 (S91). Next, it is determined whether or not the power window is open. When the power window 223 is not in the open state (S92: No), the process proceeds to step S96, and the open / close state of the next power window 223 is checked.

  On the other hand, when the power window 223 is in the open state (S92: Yes), the presence / absence of a passenger in the seat closest to the power window 223 is detected (S93). When an occupant is not detected (S94: Yes), a command is sent to the power window drive unit 221 to close the corresponding power window 223 (S95). On the other hand, when an occupant is detected (S94: No), nothing is done.

  If the process from the above-described steps S91 to S95 is executed for all power windows that can be controlled to open and close the vehicle 2 (S96: Yes), this process ends.

  In the above processing, when an occupant is detected in any seat, all the power windows may not be closed. Further, when the rainfall state information includes not only the presence / absence of rainfall but also information on the amount of rainfall, the window may be closed according to the amount of rainfall. For example, in case of light rain, the power window is opened about 10%. Also, when it is raining heavily or heavy rain, it is fully closed.

  The window closing cancel information transmission process in the server device 51 of the center 5 will be described with reference to FIG. This process is included in an application program stored in a storage medium such as an HDD (not shown) of the server device 51, and is repeatedly executed together with other processes of the application program. This process corresponds to part of the sequence SQ6 in FIG. In this processing, the server device 51 is a WWW (World Wide Web) server on the Internet, and the mobile terminal 3 is accessed using a browser operating on the mobile terminal 3.

  First, it is determined whether or not there is an access request from the mobile terminal 3 possessed by the user. When there is no access request (S71: No), this process is immediately terminated. On the other hand, when there is an access request (S71: Yes), screen data for user authentication is transmitted to the portable terminal 3 (S72). When the user inputs the user ID and password to the mobile terminal 3, the user ID is sent to the server device 51. The server device 51 refers to the DB 52 (FIG. 4B) and authenticates whether or not the received user ID and password are correct (S73). If the user ID and password are not correct (S74: No), this process is immediately terminated. Alternatively, the process returns to step S72 to prompt the user ID and password to be input again.

  On the other hand, when the user ID and password are correct (S74: Yes), the screen data for command input is transmitted to the portable terminal 3 (S75). And the command information from the portable terminal 3 is acquired (S76). It is determined whether or not the acquired command is a “cancel window closing” command.

  If it is not a “cancel window closing” command (S77: No), this process is immediately terminated. Alternatively, processing corresponding to the command is executed. On the other hand, when it is a “cancel window closing” command (S77: Yes), the vehicle ID stored in association with the acquired user ID and password is read with reference to the DB 52 (FIG. 4B) (S78). Then, the window closing cancellation information is transmitted together with the vehicle ID (S79).

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
