[Embodiment]
A vehicle window control system according to the present embodiment will be described with reference to FIGS. 1 to 4.

  FIG. 1 is an explanatory diagram showing the overall configuration of the electric vehicle according to the present embodiment. FIG. 2 is a block diagram showing a configuration example of the vehicle window control system according to the present embodiment.

(Overall structure of electric vehicle)
The electric vehicle 1 includes a power storage device 2 for storing electric power, a vehicle window opening / closing device 3 for opening / closing a window 90 provided in a door 9, a control device 4 for controlling the operation of the vehicle window opening / closing device 3, and an output. The device 5 is provided. The vehicle window control system 100 according to the present embodiment includes a vehicle window opening / closing device 3 and a control device 4. Further, the electric vehicle 1 is equipped with an electric motor 10 that generates a driving force by the electric power of a drive battery 21 of the power storage device 2 described later.

(Power storage device)
The power storage device 2 includes a drive battery 21 that stores drive power of the electric motor 10, and an auxiliary battery 22 that stores electric power for driving auxiliary devices such as lamps inside and outside the vehicle, car audio, and vehicle window opening / closing device 3. And have.

  The drive battery 21 stores electric power supplied from a charging connector (not shown). When the electric vehicle 1 is activated, the driving battery 21 reduces the battery voltage to supply electric power to auxiliary equipment such as the vehicle window opening / closing device 3, and further, the amount of electricity stored in the auxiliary equipment battery 22 is predetermined. When the voltage of the auxiliary battery 22 falls below a predetermined value, the electric vehicle 1 cannot be started. Therefore, when the voltage of the auxiliary battery 22 falls below a predetermined value, the auxiliary battery 22 is also supplied with electric power.

(Vehicle window opening / closing device)
The vehicle window opening / closing device 3 includes a switch 31 operated by an occupant, and a window elevating mechanism 32 operated by operating the switch 31. The window elevating mechanism 32 is a power window that elevates and lowers the window 90 by an electric force of a motor (not shown) electrically connected to the switch 31, for example.

(Control device)
As shown in FIG. 2, the control device 4 includes a battery remaining amount acquisition unit 41 that acquires the battery remaining amount of the driving battery 21, and a battery remaining amount acquired by the battery remaining amount acquisition unit 41 that is greater than a predetermined threshold value. A battery remaining amount determination unit 42 that determines whether or not it is low, a window position determination unit 43 that determines whether or not the window 90 is open, a window control unit 44 that controls the window elevating mechanism 32, and an instruction to the switch 31. It has an instruction invalidation unit 45 for invalidating, a warning unit 46 for warning that the window 90 is moved in the closing direction, and an instruction validating unit 47 for validating the instruction to the switch 31. The control device 4 includes, for example, a CPU (Central Processing Unit) that operates according to a program stored in advance, and its peripheral circuits. The control device 4 corresponds to the "vehicle window control device" in the present invention.

  The battery remaining amount acquisition unit 41 acquires information on the battery remaining amount of the driving battery 21 based on the result of measuring the battery voltage of the driving battery 21. Here, the battery remaining amount (SOC: State of Charge) is a value indicating the current remaining capacity with respect to the full charge capacity as a percentage (0 to 100%).

  The battery remaining amount determination unit 42 determines whether or not the battery remaining amount of the drive battery 21 acquired by the battery remaining amount acquisition unit 41 of the power storage device 2 is lower than a predetermined value. Here, the “predetermined threshold value” is a value that is determined on the assumption that the electric vehicle 1 has to be stopped due to a decrease in the battery level, and for example, the travelable distance of the electric vehicle 1 is zero. The value of the remaining battery level to be determined is set.

  Generally, in the electric vehicle 1, the value of the remaining battery amount in the drive battery 21 is not zero when the remaining battery amount determination unit 42 of the control device 4 determines that the travelable distance is zero. Therefore, even if the battery remaining amount determination unit 42 determines that the travelable distance is zero, the electric vehicle 1 does not immediately stop due to a power failure. This is because the battery remaining amount of the drive battery 21 has a margin so that the electric vehicle 1 can self-propelled and evacuate to a safe place even after the remaining battery amount determination unit 42 determines that the travelable distance is zero. This is because

  Here, if the value of the remaining battery level of the drive battery 21 for which the travelable distance is determined to be zero is set as a threshold value, the electric power remaining in the drive battery 21 before the electric vehicle 1 stops due to a power failure. The window 90 can be closed, and the anti-theft property of the electric vehicle 1 can be ensured. On the other hand, when the window 90 is closed after the electric vehicle 1 is stopped due to lack of electricity, electric power is supplied from the auxiliary battery 22, but the window 90 is closed when the auxiliary battery 22 is deteriorated or the cable is disconnected. Therefore, there arises a problem that electric power cannot be supplied. Therefore, if the value of the remaining battery level of the drive battery 21 for which the travelable distance is determined to be zero is set as the threshold value, the above problem can be solved by closing the window 90 before the electric vehicle 1 stops due to lack of electricity, Even if the electric vehicle 1 stops due to lack of electricity, it is possible to reliably prevent the electric vehicle 1 from stopping with the window 90 open.

  The window position determination unit 43 can be configured by, for example, a pulse generator including a Hall element and a magnetic rotor that generate a pulse signal at a frequency according to the rotation speed of the output shaft of the motor included in the window elevating mechanism 32. Then, the window position determination unit 43 detects the position of the window 90 by counting the number of pulses output from this pulse generator, and determines whether the window 90 is in the open state.

  The window control unit 44 controls the window elevating mechanism 32 so that the window 90 moves up or down. More specifically, when the down signal is input from the switch 31, the window control unit 44 moves down the window 90 while the signal is input and when the up signal is input from the switch 31. Controls the window elevating mechanism 32 so as to raise the window 90 while the signal is input.

  In the present embodiment, the window control unit 44 controls the window elevating mechanism 32 so that the window 90 is automatically raised according to the determination results of the battery remaining amount determination unit 42 and the window position determination unit 43. It is configured.

(Output device)
The output device 5 has a screen 51 for displaying position information such as car navigation and the state of vehicle equipment, and a speaker 52 for outputting sound. Warning information from the warning unit 46 is output to the screen 51 and the speaker 52.

(Processing contents of control device)
Next, the processing of the control device 4 according to the present embodiment will be described with reference to the flowcharts shown in FIGS. 3 and 4. FIG. 3 is a flowchart showing an example of processing of the control device 4. FIG. 4 is a flowchart showing an example of the switch (SW) operation restoration processing shown in FIG.

  As shown in FIG. 3, first, the battery remaining amount acquisition unit 41 acquires the battery remaining amount of the drive battery 21 (step S40), and the battery remaining amount determination unit 42 of the control device 4 determines the battery remaining amount in advance. It is determined whether it is lower than the threshold value (step S41). If the battery level is equal to or higher than the threshold (step S41: No), the process returns to step S40. On the other hand, when the battery level is lower than the threshold value (step S41: Yes), the window position determination unit 43 of the control device 4 determines whether the window 90 is in the open state (step S42).

  When the window 90 is in the open state (step S42: Yes), the warning unit 46 outputs the warning information to the output device 5 in such a manner as to notify the occupant of the warning information. Here, the warning unit 46 displays the fact that the window 90 is raised and the fact that the operation on the switch 31 is invalid on the screen 51 as character information, or outputs it as voice information from the speaker 52.

  Next, the window control unit 44 supplies a drive current to the window elevating mechanism 32 so that the window 90 rises, and moves the window 90 in the closing direction (step S44). Then, the instruction invalidating unit 45 invalidates the instruction to the switch 31 after the window 90 starts moving in the closing direction, and the window lifting mechanism 32 does not operate even if the occupant operates the switch 31. Thereby, even if the occupant operates the switch 31 while the window 90 is rising, the window 90 is automatically closed.

  Here, for example, when the electric vehicle 1 falls into an electric power shortage at night or in a country with poor security, the electric vehicle 1 is once stopped and waits for rescue. In this case, the window 90 is open. If so, there is a concern that the occupants will be attacked by robbery or rape. Therefore, in the present embodiment, in order to ensure the safety of the occupant, when the window control unit 44 of the control device 4 raises the window 90, the instruction invalidation unit 45 invalidates the instruction to the switch 31, The window 90 is surely closed.

  On the other hand, in the process of step S42, when it is determined that the window 90 is not in the open state (step S42: No), the warning unit 46 displays on the screen 51 that the operation on the switch 31 is invalid as the warning information. It is displayed as information or is output from the speaker 52 as audio information. Then, the instruction invalidation unit 45 invalidates the instruction to the switch 31 (step S47).

  After executing the processing of step S45 or step S47, the control device 4 executes the SW restoration processing for restoring the operation of the switch 31 (step S48).

  As shown in FIG. 4, first, the battery remaining amount acquisition unit 41 acquires the battery remaining amount of the drive battery 21 (step S481), and determines whether the battery remaining amount is equal to or more than a predetermined threshold value (step S481). S482).

  When the battery level is equal to or higher than the threshold value (step S482: Yes), the instruction validating unit 47 validates the instruction to the switch 31. As a result, the window raising / lowering mechanism 32 is activated by the signal from the switch 31. In this embodiment, for example, when the drive battery 21 is charged and the remaining battery level becomes equal to or higher than the threshold value, the window 90 can be freely moved up and down by operating the switch 31 as usual. . The threshold value in step S482 and the threshold value in step S41 may be set to different values or may be set to the same value.

  On the other hand, in the process of step S482, when the battery remaining amount is not equal to or more than the threshold value (step S482: No), the battery remaining amount of the driving battery 21 is acquired again (step S481).

  According to the present embodiment described above, window 90 is automatically raised when the remaining battery level of drive battery 21 falls below a predetermined threshold value, so that electric vehicle 1 is temporarily stopped due to a power failure. However, it is possible to prevent the window 90 from stopping in the open state. That is, the anti-theft property can be secured in the electric vehicle 1.

  Further, according to the present embodiment, when the remaining battery level falls below the threshold value, window 90 is moved in the closing direction, and the instruction to switch 31 after the start of this movement is nullified. Therefore, the movement of the window 90 in the closing direction is not hindered. Therefore, it is possible to close the window 90 more reliably as compared with the case where the instruction to the switch 31 is not invalidated. As a result, the anti-theft property against the electric vehicle 1 stopped due to the lack of electricity and the safety of the occupant in the passenger compartment are ensured.

  According to the present embodiment, since control device 4 has warning portion 46, when window 90 rises when the battery level is lower than a predetermined threshold value, the rise in window 90 causes the battery level to remain. It is possible to inform the occupant that it is due to the decrease in the amount. This can give the passenger a sense of security. This also applies to warning that the switch 31 is invalidated.

  Although the embodiments of the present invention have been described above, the embodiments described above do not limit the invention according to the claims. Further, it should be noted that not all the combinations of features described in the embodiments are essential to the means for solving the problems of the invention.

  In the above-described embodiment, the battery remaining amount determination unit 42 of the control device 4 determines whether or not it is lower than a predetermined threshold value, and controls the window 90 to move in the closing direction based on the determination result. However, it is not limited to this. For example, the threshold may be set by the occupant. In this case, the screen 51 of the output device 5 may display information for setting or selecting the threshold value.

  Further, in the above-described embodiment, the window 90 provided in the vehicle door as the vehicle window has been described as an example, but the vehicle window of the present invention is not limited to the glass window, and the vehicle opening It may be an openable / closable body that opens and closes the portion, and may be, for example, a sliding roof or a sunroof. The present invention can be appropriately modified and implemented without departing from the spirit of the present invention.
