Description

The present invention relates to a window opening/closing device for a vehicle. In particular, the present invention relates to an improvement in a window opening/closing device for a vehicle that automatically opens/closes a window according to a commanded opening degree.

Conventionally, for example, as disclosed in Patent Document 1, an automatic window opening/closing operation is performed according to the window opening degree (instruction opening degree) instructed by a passenger's window opening/closing instruction operation (for example, operation of a display screen in the vehicle interior). Window opening/closing devices (power window devices) are known.

Specifically, in Patent Document 1, the opening degree of a window (power window) is shown as an opening rate, and when the window is fully closed, the opening degree is 0%, and when the window is fully open, the opening degree is 100%. It is disclosed that the degree of opening (opening rate) is defined by dividing the range from 0% to 100% at equal intervals.

Furthermore, in Patent Document 1, the current window opening degree is displayed on a display screen (screen of a car navigation device, etc.) installed in the vehicle interior, for example, as shown in FIG. When an opening range is assigned to each indicated opening, if the actual opening of the window is in the range of 30% or more and less than 40%, the window opening will be displayed as 30% on the display screen. If a message to that effect is displayed and the actual degree of opening of the window is in the range of 40% or more and less than 50%, a message indicating that the degree of window opening is 40% will be displayed on the display screen. It has become. This allows the occupant of the vehicle to check the opening degree of the window from the display on the display screen without directly looking at the window.

However, in the conventional technology, this is caused by a difference in the stop position of the window between when the window is closed (raised) and when the window is opened (lowered). However, this may lead to a situation where the instructed opening degree and the opening degree displayed on the display screen (hereinafter also referred to as the displayed opening degree) do not match.

The reason for this situation is that even if the indicated opening is the same, there is a difference in the stopping position of the window when the window is closed and when it is opened. be. In other words, in the window closing operation, the window stops when the window opening reaches the commanded opening, and after that, the window moves slightly upward (in the closing direction) due to the inertia of the window. , the window will stop. On the other hand, when opening a window, the window stops when the window reaches the commanded opening, and then moves slightly downward (in the opening direction) due to the inertia of the window. After that, the windows will stop working. In this way, due to the slight movement of the window after reaching the indicated opening, even if the indicated opening is the same (the indicated opening for the window closing operation and the indicated opening for the window opening operation) If the actual window stop positions are different and the opening ranges to which each stop position (actual opening degree) belongs are different from each other, the window closing operation and the window In some opening operations, an opening degree different from the instructed opening degree may be displayed on the display screen. In other words, when the window opens and closes at the same indicated opening and the window stops, the window closes even though the openings are approximately the same (if the openings differ by the amount of the deviation). There was a possibility that the displayed opening degree would be different depending on whether the window opening operation was performed or the window opening operation was performed. Such a situation is undesirable because it gives the occupants a sense of discomfort.

Specifically, for example, if the relationship between each instructed opening degree and each opening range is defined as shown in FIG. 4, when a closing operation is performed with the instructed opening degree of 40%, In some cases, the window opening degree after the vehicle stops is 39%, which is displayed as 30% on the display screen. If such a situation occurs, the window will hardly move even if you subsequently perform an operation to instruct the window to open or close (operate to instruct the open side) so that the opening degree is 40%. This situation also gives the occupants a sense of discomfort.

The present invention has been made in view of the above, and an object of the present invention is to provide a window opening/closing device for a vehicle that can realize an automatic window opening/closing operation that prevents passengers from feeling uncomfortable. It is in.

The solution of the present invention to achieve the above object includes a display that allows the passenger to set or select the indicated opening degree of the window and a display screen that can display the current opening degree of the window. a display device in which a plurality of opening degrees other than the respective opening degrees of a fully closed state and a fully open state of the window are defined as the instructed opening degree, and an automatic opening/closing operation of the window is performed according to the instructed opening degree. This assumes that the vehicle has a window opening/closing device. The window opening/closing device of this vehicle has a predetermined opening range including the specified opening degree assigned to each of the plurality of specified opening degrees, and a window opening/closing device for detecting the opening degree of the window. a current opening degree determining unit that determines the indicated opening degree included in the opening degree range to which the opening degree of the window detected by the opening degree detection unit belongs as the current opening degree; The lower limit value of the opening range that is assigned to each of the plurality of indicated opening degrees is smaller than the indicated opening included in the opening range by a predetermined value, and is assigned to each of the plurality of instructed opening degrees. The upper limit value of the opening range is set to be larger than the indicated opening included in the opening range by a predetermined value, and when the window stops, the window detected by the opening detection unit deviates from the indicated opening, the indicated opening to which the opening range to which the detected opening belongs is assigned is displayed on the display screen of the display device as the current opening. It is characterized by being configured to .

Due to this specific matter, even if there is a difference in the stop position of the window between when the window is closed and when the window is opened, the The lower limit of the opening range assigned is a predetermined value smaller than the indicated opening included in the opening range, and the upper limit of the opening range is a predetermined value smaller than the indicated opening included in the opening range. Since the value is set large, it is possible to keep the deviation amount of the opening degree from the indicated opening degree in both the window closing operation and the window opening operation within the opening degree range assigned to the specified opening degree. , the current opening determined by the current opening determining section (the current opening determined as the indicated opening included in the opening range to which the detected window opening belongs) matches the indicated opening. Become. For example, if the current opening degree is displayed on the display screen, the opening degree displayed on the display screen will match the instructed opening degree. Therefore, it is possible to realize an automatic window opening/closing operation that prevents the occupant from feeling uncomfortable.
In addition, the window has a fully closed state when it is the most elevated state within the vertical range, and a fully open state when it is the most descended state, and the lower limit value of the opening degree range and the lower limit value are different from each other. The difference between the indicated opening degree to which the opening range to which the belonging range belongs is greater than the difference between the upper limit value of the opening range and the indicated opening degree to which the opening range to which the upper limit value belongs is assigned. It is set.

In the present invention, a predetermined opening range including the specified opening degree is assigned to each of a plurality of prescribed opening degrees, and a predetermined opening range including the specified opening degree is assigned to each of the prescribed opening degrees. The lower limit value is set to be a predetermined value smaller than the indicated opening included in the relevant opening range, and the upper limit value of the opening range assigned to each of the multiple indicated openings is set as the indicated opening included in the relevant opening range. It is set larger than the opening degree by a predetermined value. As a result, even if there is a difference in the stop position of the window between when the window is closed and when the window is opened, the current opening determined by the current opening determining section can be maintained. It is possible to realize an automatic opening/closing operation of the window that can match the instruction opening degree and prevent the occupant from feeling uncomfortable.

As shown in FIG. 1, the window opening/closing device 100 includes window operating units 101, 102, 103, 104 provided in each of the four doors, a vehicle control ECU (Electronic Control Unit) 200, a roof shade for each window, and a roof shade for each window. It includes motor control ECUs 301, 302, 303, 304, and 305 arranged correspondingly to each other, and a display device (display) 400 provided in a car navigation device or an instrument panel. These window operating units 101 to 104, vehicle control ECU 200, motor control ECUs 301 to 305, and display device 400 are connected via an in-vehicle network called CAN (Controller Area Network).

The window operating units 101 to 104 each have an operating switch provided for each door of the automobile (driver's seat door, passenger's seat door, right rear seat door, and left rear seat door). When these window operation units 101 to 104 detect an operation of an operation switch (operation by a passenger), they output an operation detection signal to the vehicle control ECU 200.

The window operating sections include a driver's seat window operating section 101, a passenger's seat window operating section 102, a right rear seat window operating section 103, and a left rear seat window operating section 104.

The driver's side window operation unit 101 includes operation switches that can operate the driver's side door window, the passenger's side door window, the right rear seat side door window, the left rear seat side door window, and the roof shade. ing. This driver's side window operation section 101 transmits an operation detection signal according to the operated operation switch to the vehicle control ECU 200. That is, information on the type of operated operation switch and its operation direction (opening operation direction or closing operation direction) is transmitted to vehicle control ECU 200 as an operation detection signal.

The passenger side window operation unit 102 includes an operation switch that can operate the window of the passenger side door. This passenger seat side window operation section 102 transmits an operation detection signal (information on the opening operation direction or the closing operation direction) according to the operation of the operation switch to the vehicle control ECU 200.

The right rear seat window operating section 103 includes an operation switch that can operate the window of the right rear seat door. This right rear seat side window operation section 103 transmits an operation detection signal (information on the opening operation direction or the closing operation direction) according to the operation of the operation switch to the vehicle control ECU 200.

The left rear seat window operating section 104 includes an operation switch that can operate the window of the left rear seat door. This left rear seat side window operation section 104 transmits an operation detection signal (information on the opening operation direction or the closing operation direction) according to the operation of the operation switch to the vehicle control ECU 200.

The vehicle control ECU 200 is composed of a well-known microcomputer including a CPU, ROM, RAM, etc., and its peripheral circuits, and outputs control signals to various control ECUs for controlling various actuators mounted on the vehicle. In FIG. 1, only the motor control ECUs 301 to 305 are shown as control ECUs.

When the vehicle control ECU 200 receives an operation detection signal from any one of the window operation units 101 to 104, the vehicle control ECU 200 issues opening/closing instructions to the motor control ECUs 301 to 305 corresponding to the operation detection signal in accordance with the operation detection signal. Send a signal. For example, when an operation detection signal for the window of the driver's side door is received from the driver's side window operation unit 101, an opening/closing instruction signal is sent to the motor control ECU 301 corresponding to the driver's side window in accordance with this operation detection signal. Send.

Further, in this embodiment, the occupant can set or select the indicated opening degree on the display screen of the display device 400. In other words, using a display and a touch panel, a GUI (Graphical User Interface) for instructing the opening is constructed on the display, and the instructed opening of the window or roof shade can be set or selected by operating the screen of this GUI. be. When the occupant sets or selects the indicated opening degree on the display screen of the display device 400, the indicated opening signal is transmitted from the display device 400 to the vehicle control ECU 200, and the vehicle control ECU 200 selects the motor corresponding to the instructed opening degree signal. The instruction opening signal will be transmitted to the control ECUs 301 to 305. The display on the display screen of this display device 400 will be described later.

Note that the setting of the indicated opening degree here assumes a case where a numerical value (percentage) of the opening degree is inputted by the passenger's operation on the display screen of the display device 400. Furthermore, the selection of the indicated opening degree here assumes that a plurality of numerical values (percentages) of selectable opening degrees are displayed on the display screen of the display device 400, and a selection is made from among them by the operation of the passenger. do. In this case, the commanded opening degree (percentage of the opening degree) is set by the vehicle control ECU 200 according to the selected numerical value.

Motor control ECUs 301 to 305 control motors 501 to 505 for regulators provided in each door of the automobile (driver's side door, passenger's side door, right rear seat door, left rear seat door) and roof shade, respectively. This is an ECU for

The motor control ECUs include a motor control ECU 301 for the driver's side window, a motor control ECU 302 for the passenger side window, a motor control ECU 303 for the right rear seat window, a motor control ECU 304 for the left rear seat window, and a motor control ECU 305 for the roof shade. It is equipped with

Motors 501 to 505 are connected to each motor control ECU 301 to 305, and the corresponding motors 501 to 505 operate according to drive command signals from each motor control ECU 301 to 305, thereby causing each window and roof shade to operate. One of them is designed to automatically open and close.

In addition, each motor control ECU 301 to 305 has a function to detect the actual opening degree of a window or roof shade, and information on the opening degree of the window or roof shade (opening detection signal) is used to control the vehicle. It is designed to be output to the ECU 200. As means for detecting the opening degree of the actual window or roof shade, it is possible to use a well-known rotary encoder or to detect based on a pulse signal when using a stepping motor, but in particular It is not limited. The functional part that detects the opening degree of the window and the roof shade constitutes an opening detection section (an opening detection section that detects the opening degree of the window) in the present invention.

The display device 400 displays the current opening degree of each window and roof shade as an opening rate. Specifically, when the window is fully closed, the opening degree is 0%, and when the window is fully open, the opening degree is 100%, and the degree of opening (opening rate) is determined by dividing the range from 0% to 100% into 10% intervals. is now displayed.

Specifically, as will be described later, a predetermined opening range including the designated opening degree is assigned to each of a plurality of designated opening degrees defined at 10% intervals. Then, the vehicle control ECU 200 receives an opening detection signal (actual opening information) from each of the motor control ECUs 301 to 305, and the opening of each window and roof shade detected based on this opening detection signal ( The commanded opening to which the opening range to which the actual opening falls belongs is set as the current opening, and the opening information is transmitted from the vehicle control ECU 200 to the display device 400 so that the current opening is displayed on the display device 400. The opening degree of each window and roof shade is displayed by the opening rate.

The display of the opening degrees of each window and roof shade on this display device 400 is performed by interrupt display. That is, in normal times, a normal display based on an output signal from a car navigation device or an AV (Audio Visual) device is displayed on the display screen, but opening degree information from vehicle control ECU 200 is transmitted to display device 400. Accordingly, opening degree information is displayed at least partially on the display screen. Note that the interrupt display of the opening degree information on the display device 400 is erased after a predetermined period of time has elapsed after the start of display.

Next, a display example of the power window operation state on the display device 400 will be described. FIG. 2 is a diagram showing an example of a display on the screen of the display device 400 during power window operation. As shown in FIG. 2, the display screen of the display device 400 includes a driver side window opening display section 401 that displays the opening degree of the driver's side window, and a passenger side window opening degree display section 401 that displays the opening degree of the passenger side window. A window opening degree display section 402, a right rear seat side window opening degree display section 403 that displays the opening degree of the right rear seat side window, a left rear seat side window opening degree display section 404 that displays the opening degree of the left rear seat side window. is provided. In other words, when any one of the window operating units 101 to 104 is operated, or when the indicated window opening degree is set or selected by screen operation on the display screen of the display device 400, these opening degree display units The screen can be switched to displaying 401 to 404. Although not shown, an opening degree display section that displays the opening degree of the roof shade may also be displayed. Further, the opening degree display section that displays the opening degree of the roof shade is displayed when the operation switch for operating the roof shade in the driver's side window operation section 101 is operated or when the screen operation on the display screen of the display device 400 is performed. The display may be displayed only when the indicated opening degree of the shade is set or selected.

In the state shown in Figure 2, the current window openings are 20% for the driver's side window, 50% for the passenger's side window, 50% for the right rear seat window, and 50% for the right rear seat window. When the operation switch of the right rear seat side window operation section 103 is operated in the opening operation direction from the state where the opening degree of the rear seat side window is 0%, or by operating the display screen of the display device 400, the right rear seat side window is opened. This shows a case where the indicated opening degree of the window is set. When such an operation is performed, the window opening display section 403 on the right rear seat side is displayed enlarged compared to the other opening display sections 401, 402, and 404, and the window movement direction (in FIG. In some cases, an arrow in the downward direction is displayed.

- Assignment of opening range -
As described above, a predetermined opening range is assigned to each of the indicated opening degrees. FIG. 3 is a diagram for explaining the opening degree ranges assigned to each instructed opening degree.

As shown in FIG. 3, in this embodiment, an opening degree range is assigned to the instructed opening degree. Specifically, an opening range of 0% to 4% (0% or more and less than 4%) is assigned to the indicated opening of 0%, and an opening range of 5% to 14% (5% to 14%) is assigned to the indicated opening of 10%. 5% or more and less than 14%), and the opening range is 15% to 24% (15% or more and less than 24%) for the indicated opening of 20%, and the opening range is assigned for the indicated opening of 30%. 25% to 34% (25% or more and less than 34%) is assigned, and an opening range of 35% to 44% (35% or more and less than 44%) is assigned to the indicated opening of 40%, and the indicated opening is 50%. An opening range of 45% to 54% (45% or more and less than 54%) is assigned to the specified opening, and an opening range of 55% to 64% (55% or more and less than 64%) is assigned to the indicated opening of 60%. , an opening range of 65% to 74% (65% or more and less than 74%) is assigned to the indicated opening of 70%, and an opening range of 75% to 84% (75% or more and 84%) is assigned to the indicated opening of 80%. (less than %) is assigned, an opening range of 85% to 94% (85% or more and less than 94%) is assigned to the indicated opening of 90%, and an opening range of 95% to 100 is assigned to the indicated opening of 100%. % (more than 95%) is allocated.

In other words, the lower limit value of the opening range assigned to each indicated opening except 0% indicated opening and 100% indicated opening is smaller by a predetermined value than the indicated opening included in the relevant opening range. (5% smaller in this embodiment), and the upper limit of the opening range assigned to each of the plurality of instructed openings is a predetermined value smaller than the instructed opening included in the corresponding opening range. It is set large (4% larger in this embodiment). Therefore, the "prescribed plurality of specified opening degrees" in the present invention corresponds to each of the specified opening degrees from 10% to 90%. Note that each instruction opening degree and each opening degree range are defined in a one-to-one correspondence relationship. In other words, when one designated opening degree is determined, one opening range corresponding thereto is also specified, and one designated opening degree corresponds to one opening degree range.

Then, the current window opening degree (the current opening degree displayed on the display screen of the display device 400) is determined depending on which range the actual opening degree of the window belongs to. In other words, if the actual opening degree of the window is within the range of 0% to 4%, the current opening degree (the current opening degree displayed on the display screen of the display device 400) is set to 0%, and the window opening degree is set to 0%. If the actual opening degree is within the range of 5% to 14%, the current opening degree is set to 10%, and if the actual opening degree of the window is within the range of 15% to 24%, the current opening degree is set to 10%. If the current opening is 20% and the actual opening of the window is within the range of 25% to 34%, then the current opening is 30% and the actual opening of the window is 35% to 44%. If the actual opening of the window is within the range of 45% to 54%, the current opening is set to 50%. If the actual opening degree is within the range of 55% to 64%, the current opening degree is set to 60%, and if the actual opening degree of the window is within the range of 65% to 74%, the current opening degree is set to 60%. If the current opening is 70% and the actual opening of the window is within the range of 75% to 84%, then the current opening is 80% and the actual opening of the window is 85% to 94%. If the actual opening of the window is within the range of 95% to 100%, the current opening is determined to be 100%. I have to. In this way, the functional part (for example, the functional part constructed in the vehicle control ECU 200) that determines the current opening degree according to the actual opening degree of the window enables the current opening degree determination part (opening degree detection part) as referred to in the present invention. A current opening determination unit is configured to determine, as the current opening, a commanded opening included in the opening range to which the detected window opening belongs.

In the actual window opening/closing operation, there is a difference in the stop position of the window between when the window is closed (raised) and when the window is opened (lowered). become. Specifically, in the window closing operation, the window stops when the window opening reaches the commanded opening, and then the window moves slightly upward (in the closing direction) due to the inertia of the window. ), the window will stop working. On the other hand, when opening a window, the window stops when the window reaches the commanded opening, and then moves slightly downward (in the opening direction) due to the inertia of the window. After that, the windows will stop working. This situation also occurs during the opening and closing operations of the roof shade.

In the conventional technology, due to the slight movement of the window after reaching the indicated opening, even if the indicated opening is the same (the indicated opening for the window closing operation and the indicated opening for the window opening operation) Even if the opening degrees are the same), if the actual stop positions of the window are different from each other and the opening ranges to which each stop position (actual opening degree) belongs are different from each other, the window cannot be closed. In either the operation or the window opening operation, an opening degree different from the instructed opening degree may be displayed on the display screen. Such a situation is undesirable because it gives the occupants a sense of discomfort.

Specifically, for example, when the relationship between each indicated opening and each opening range is defined as shown in FIG. In this case, when a closing operation is performed with the indicated opening degree of 40%, the opening degree of the window after stopping becomes 39%, which may be displayed as 30% on the display screen. If such a situation occurs, the window will hardly move even if you subsequently perform an operation to instruct the window to open or close (operate to instruct the open side) so that the opening degree is 40%. This situation also gives the occupants a sense of discomfort.

In contrast, in the present embodiment, even in a situation where the stop position of the window deviates between when the window is closed and when the window is opened, as described above, The lower limit value of the opening range assigned to each of the plurality of prescribed opening degrees is smaller by a predetermined value (5% in this embodiment) than the designated opening degrees included in the opening range. The upper limit value of the opening range is set to be larger than the commanded opening included in the opening range by a predetermined value (4% in this embodiment). Therefore, it is possible to keep the deviation amount of the opening degree from the instructed opening degree in both the window closing operation and the window opening operation within the opening degree range assigned to the instructed opening degree. The current opening determined by (the current opening determined as the indicated opening included in the opening range to which the detected window opening belongs) matches the indicated opening. In other words, the instruction opening degree instructed by the occupant matches the opening degree displayed on the display screen of display device 400.

For example, when a window is closed with the indicated opening degree set to 40%, even if the window stop position shifts to 38% (a shift of 2% occurs), even if the window is currently opened. The current opening degree determined by the degree determination section is 40%, and this current opening degree is displayed on the display screen of the display device 400, which matches the instructed opening degree. In addition, when a window opening operation is performed with the indicated opening degree of 40%, even if the stop position of the window shifts to 42% (a shift of 2% has occurred), even if the window is currently opened. The current opening degree determined by the degree determination section is 40%, and this current opening degree is displayed on the display screen of the display device 400, which also matches the instructed opening degree in this case. In this way, even if there is a difference in the stop position of the window between when the window is closed and when the window is opened, the It becomes possible to keep the deviation amount of the opening degree from the instructed opening degree within the opening degree range assigned to the instructed opening degree, and the instructed opening degree instructed by the crew member and the opening degree displayed on the display screen of the display device 400 can be adjusted. The degree will match.

Since the instructed opening degree and the opening degree displayed on the display screen of the display device 400 match in this way, when the window opening/closing instruction operation is further performed from this state, the window hardly moves. It is possible to realize an automatic window opening/closing operation that does not cause any unpleasant situations and prevents passengers from feeling uncomfortable.

-Other embodiments-
Note that the present invention is not limited to the embodiments described above, and all modifications and applications are possible within the scope of the claims and equivalent ranges thereof.

For example, in the above embodiment, when the present invention is applied as a window opening/closing device for a vehicle that automatically opens/closes the windows provided in each of the four doors and automatically opens/closes the roof shade provided on the roof. explained. The present invention is not limited to this, and can also be applied as a window opening/closing device for a vehicle that only automatically opens/closes a window provided in a door. Further, the number of windows on which automatic opening/closing operations are performed is not limited to four.

Further, in the embodiment described above, the opening degree ranges assigned to each of the plurality of instructed opening degrees are shown in FIG. In other words, for each indicated opening except 0% and 100%, a value that is 5% smaller is the lower limit of the opening range, and a value that is 4% larger for each indicated opening is set as the lower limit of the opening range. This is the upper limit of the opening range. The present invention is not limited to this, and the lower limit of the opening range assigned to each of the plurality of indicated openings is smaller by a predetermined value than the indicated opening included in the opening range, and It is only necessary that the upper limit value of the opening degree range assigned to each instructed opening degree is set to be larger than the instructed opening degrees included in the opening degree range by a predetermined value.

Further, in the embodiment described above, the indicated opening degree is defined as an opening degree divided into 10% intervals. The present invention is not limited to this, and the indicated opening degree may be defined as an opening degree divided into intervals of less than 10%, or may be defined as an opening degree divided into intervals of more than 10%.

Moreover, in the embodiment, the window opening/closing operation is performed with the instructed opening degree as the target opening degree, regardless of whether the window is closed or opened. The present invention is not limited to this, and even if the instructed opening degree is the same, the target opening degree may be made different between the closing operation and the opening operation of the window. For example, when a window is to be closed, the target opening is set by adding a predetermined amount (for example, about 2%) to the indicated opening (larger opening), and the window is opened. In this case, the target opening degree may be set as an opening degree (smaller opening degree) obtained by subtracting a predetermined amount (for example, about 2%) from the instructed opening degree. This makes it possible to further reduce the deviation amount of the opening degree from the instructed opening degree.
