JPS63101127A - Window opening/closing control device for vehicle - Google Patents

Abstract

PURPOSE:To automate the operation of the opening switch of a power window device by providing a boarding detecting means detecting that a person is on board and opening the window if boarding is detected and the temperature in a vehicle room is a reference value or more. CONSTITUTION:A door is opened when a person rides on a vehicle, and this change that the door is opened is detected by a door switch 6. If it is thus judged that the person is on board, a temperature sensor 7 reads the temperature in a vehicle room, and whether it is a reference value or more is judged. As a result, if the room temperature is the reference value or more, a command to open a window is given to a power window drive circuit 2. Thereby, a motor 1 opens the window. According to this window opening/closing control device, the window is automatically opened when the person rides into a hot vehicle room, thus the trouble of operating a switch can be saved.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a window opening/closing control device for an automobile, and in particular, it adds a new function to an automobile equipped with a power window device that drives the window opening/closing by a motor. be.

(Prior Art) Power window devices capable of automatically opening and closing windows by operating a switch are widely used in general automobiles (see, for example, Japanese Utility Model Application Publication No. 59-57679).

(Problems to be Solved by the Invention) Naturally, even in an automobile equipped with a power window device, it is necessary to operate a switch to open and close the window. In some cases, even operating this switch may feel troublesome. For example, when getting into a parked car during the day in a hot season, the interior of the car gets quite hot, so almost everyone always opens the window. Even when using an air conditioner, the cooling effect cannot be expected immediately, so it is common to leave the windows open for a while. Under such circumstances, it would be convenient if the operation of the open switch of the power window device could be omitted.

The present invention has been made based on the above-mentioned viewpoint, and its purpose is to provide an automobile window opening/closing control device that automatically opens the window when the passenger gets into a hot vehicle interior. be.

(Means for Solving the Problems) The window opening/closing control means of the present invention, in an automobile equipped with a power window device that opens and closes a window by a motor, includes an occupant detection means for detecting that a person has entered the vehicle, and an occupant detection means for detecting that a person has entered the vehicle; temperature detecting means for detecting that the temperature of the passenger compartment has exceeded a reference value; It is equipped with a control means for driving the opening.

(Function) When a person gets on the vehicle, the rider detection means detects this. At that time, if the temperature detection means detects that the temperature inside the vehicle is higher than the reference value, the control means operates;
Drive the window open.

(Example) In Fig. 1, 1 is a motor that is an actuator of a power window device, 2 is a drive circuit for the motor 1, and when the window close switch 3 is turned on, the motor 1 is rotated in the normal direction to open the window. When the window close switch 4 is turned on, the motor 1 is reversely driven to close the window.

In addition to the above functions, the power window drive circuit 2 also drives the motor 1 in response to a window open command and a window close command from the control circuit 5 according to the present invention.

The control circuit 5 receives a switch signal from a door switch 6, which is turned on and off in conjunction with the opening and closing of the door, and a detection signal from a temperature sensor 7, which detects the temperature inside the vehicle, and also controls the blinking of an alarm lamp 8. This circuit 5 performs this.

The door switch 6 is a main part of the occupancy detection means. When someone gets into a parked car, first open the closed door. This door switch 6 changes from closing to opening the door.
It is detected that a person has entered the vehicle.

FIG. 2 shows a control procedure by the control circuit 5. First, in the first step 100, the state of the door switch 6 is checked, and the timing at which the door changes from closed to open is detected. When the door changes from closed to open, the process proceeds to step 101, in which the temperature inside the vehicle is read from the temperature sensor 7, and in the next step 102, it is determined whether the temperature is equal to or higher than a reference value. If the temperature inside the vehicle is lower than the standard value, take the first step 1.
Return to 00. If the vehicle interior temperature is equal to or higher than the reference value, the process proceeds to step 103, where a window opening command is given to the power window drive circuit 2. This causes the motor 1 to drive the window open.

Next, in step 104, a timer set for a certain period of time is activated, and in the next step 105, the timer waits for the timer to time up. If the time has expired, the process proceeds to step 106, where the alarm lamp 8 is turned on, and then, in step 107, a window close command is given to the power window drive circuit 2, and the process returns to the first step 100. This allows motor 1
drives the window closed.

As is clear from the above, when a person opens the door to get into the vehicle interior, which is hotter than the standard value, the window is automatically opened, and after a certain period of time, the window is automatically closed again. .

Note that the power window drive circuit 2 gives priority to the open command or close command from the switch 3 or 4 over the window open command or close command from the control circuit 5. That is, even if a window opening command is given from the control circuit 5, if the window closing switch 4 is turned on, the motor 1 drives the window to close.

Next, other embodiments of the present invention will be described.

The setting time of the timer may be configured to be changed depending on whether a person gets into a hot car and turns on the air conditioner or not. When the cooling switch is turned on, the set time of the timer is shortened, and when the cooling switch is not turned on, the set time of the timer is lengthened.

Further, when the cooling switch is turned on, the function of automatically opening the window may be completely disabled.

Further, as the occupancy detection means, a seat switch may be used that is turned on and off depending on whether or not the weight of the occupant is applied to the seat.

Further, although the above-mentioned warning lamp 8 is used to notify that the window will automatically close, notification may be provided by a buzzer or a synthesized sound in addition to the lamp.

(Effects of the Invention) As explained in detail above, according to the automobile window opening/closing control device according to the present invention, the window is automatically opened when a person gets into the hot car, thereby eliminating the trouble of operating the switch. This makes the power window device even more useful.
