Description

[Detailed description of the invention]

[Object of the Invention] (Industrial Application Field) The present invention relates to a device for automatically opening and closing a roof panel of a vehicle. (Prior art) The roof panel of a vehicle is, for example,
As disclosed in No. 030832, it is opened and closed by a manually operated handle. In addition, the opening and closing mechanism is electric,
Some roof panels are operated by a switch to instruct the roof panel to open and close, and in response to this command, the motor energizing circuit automatically opens and closes the roof panel. Japanese Unexamined Patent Publication No. 55-140611 discloses that a vehicle speed detection means is coupled to this motor energizing circuit, so that when the roof panel is open and the vehicle speed exceeds a predetermined high speed value, the roof panel is automatically closed even if there is no instruction to close it by operating a switch. An automatic closing device has been proposed which automatically drives the roof panel closed. Furthermore, in Japanese Patent Application Laid-open No. 57-66014, a water detection sensor installed on the outer surface of the vehicle roof is coupled to an electric motor energizing circuit that opens and closes the roof panel in response to a switch operation, and this detects water. An automatic closing device is proposed that automatically drives the roof panel closed when the roof panel is closed. In addition, Japanese Utility Model Publication No. 57-6476 discloses that in order to rapidly lower the temperature inside the vehicle when the vehicle is left in the hot sun, the vehicle is equipped with an interior temperature sensor and an exterior temperature sensor. Automatic control is disclosed that opens the window glass when the temperature is detected and closes the window glass when the inside temperature drops to the outside temperature. (Problems to be Solved by the Invention) The automatic closing device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 55-140611 automatically closes the roof panel at critical speeds, but the interior comfort of the vehicle is adjusted to suit the interior environment and atmospheric environment. The automatic opening and closing of the roof panel for the improvement of
In order to ensure vehicle driving safety, automatic closing of the roof panel in response to dangerous speeds should be considered separately or in a complementary relationship. The automatic closing device of the above-mentioned Japanese Patent Application Laid-open No. 57-66014 is as follows:
Although this point is taken into consideration, when the roof panel is open and the detection sensor detects water, the roof panel is only driven to close, which means that the interior environment is deteriorated due to the external environment (rainwater) passing through the roof opening. The above-mentioned Japanese Patent Application Laid-Open No. 55-140611
The automatic closing device disclosed in the above publication is similar, but the interior comfort of the vehicle cannot be positively improved without imposing a particular burden on the driver (for example, attention). The technique disclosed in the above-mentioned Japanese Utility Model Application Publication No. 57-6746 is applicable only to special situations under the scorching sun. In vehicles, as described above, windows are controlled to be closed for safety reasons related to vehicle speed, windows are controlled to be closed to prevent rain from getting inside the vehicle, and windows are closed to prevent hot air from inside the vehicle under the scorching sun. In addition to, or in addition to, controlling the opening of the windows, the system automatically opens the roof panel in response to deterioration of the interior environment and prevents sunlight from directly hitting the passengers. It is preferable to automatically close the roof panel. As mentioned above, there is a suggestion to automatically close the window by detecting the external environment, so consider sunlight as one of the external environments, detect it with a sensor, and close the window when the sunlight is too strong. may be considered as a concept. However, since the sun moves on a diurnal cycle and the vehicle takes its own course, the relative relationship between the vehicle and the sun changes significantly while the vehicle is being driven. Opening/closing control of the roof panel is not possible. The present invention automatically detects direct sunlight that is inappropriate for opening the roof panel depending on the relative relationship between the vehicle's traveling direction and the position of the sun, and prevents sunlight from entering the vehicle interior through the window opening of the roof panel. The purpose is to automatically prevent [Structure of the Invention] (Means for Solving the Problems) A vehicle roof panel opening/closing device of the present invention is an electric opening/closing positioning mechanism that is coupled to a roof panel and drives the roof panel to open/close; an electric energizing circuit for energizing; an instruction means for instructing opening/closing of the roof panel; a photo sensor with a light-receiving surface facing upward; Blocks the incidence of light at a predetermined angle β or less from the rear to the photo sensor, blocks the incidence of light from the right at a predetermined angle γ or less from the right, and blocks the incidence of light from the left at a predetermined angle θ or less to the photo sensor. a direct sunlight sensor comprising a light shielding member that blocks the incidence of light; and a direct sunlight sensor that instructs the electric energizing circuit to open/close in response to an open/close instruction from the instruction means; Panel opening/closing control means for instructing the electric energizing circuit to close in response to detection of light incident on the photo sensor. The predetermined angle α is a critical angle of incidence of sunlight on the photo sensor at which sunlight passing through the roof opening from the front of the vehicle does not directly strike the head of the occupant in the rear seat. The predetermined angle β is a critical angle of incidence of sunlight on the photo sensor at which sunlight passing through the roof opening from the rear of the vehicle does not directly strike the head of the occupant in the front seat. The predetermined angle γ is a critical angle of incidence of sunlight on the photo sensor at which sunlight passing through the roof opening from the right side of the vehicle does not directly strike the head of the occupant in the left seat. And the predetermined angle θ
is a critical angle of incidence of sunlight on the photo sensor at which sunlight passing through the roof opening from the left side of the vehicle does not directly strike the head of the occupant in the right seat. (Function) According to the direct sunlight sensor configured as described above, since it is provided with the light shielding member, the photo sensor of the direct sunlight sensor detects that sunlight is coming from the front of the vehicle at an angle α or more, from the rear of the vehicle at an angle β or more, and from the right side of the vehicle. When sunlight is directly incident from the left side of the vehicle at an angle γ or more, or from the left side of the vehicle at an angle θ or more, the panel opening/closing control means detects the incidence of light. In response, the roof panel is controlled to close, so no matter what direction the vehicle is facing, it will move toward the front of the vehicle (90°) from the vertical line (directly above the center).
−α)°, towards the rear of the vehicle from the vertical line (90−β)
The solar irradiation angle is within the cone-shaped area formed by the virtual planes of ゜, (90-γ)゜ to the left of the vehicle from the vertical line, and (90-θ)゜ to the left of the vehicle from the vertical line. Sometimes, that is, when strong sunlight shines directly into the vehicle interior through the roof panel opening/closing window, the roof panel is automatically closed. Therefore, in the present invention, the shading angle α of the shading member is set to be the critical incidence angle of sunlight at which sunlight passes through the roof opening and does not hit the head of the occupant in the rear seat when sunlight is received from the front, and β is the critical incidence angle of the sun rays from the rear. Let γ be the critical incidence angle of sunlight at which direct sunlight does not hit the head of the passenger in the front seat when receiving sunlight from the right side, and γ is the critical angle at which direct sunlight does not hit the passenger in the left seat when sunlight is received from the right side. and θ is the critical angle of incidence at which direct sunlight does not hit the head of the right seat occupant when sunlight is received from the left, so when the roof panel is open, the head of any of the above occupants When there is direct sunlight, such as when direct sunlight hits the roof panel, the roof panel automatically closes and the sunlight is blocked or attenuated by the roof panel. When the angle of incidence of sunlight is lower than the cone-shaped area, or when the sunlight is weak (for example, on a cloudy day), the roof panel is not driven to close in response to outside light, and the roof panel is not driven to close in response to the vehicle's exterior light. The roof panel remains open in response to the environmental sensor. Therefore, the functionality of the roof panel is improved, and the comfort inside the vehicle is improved even under strong sunlight and regardless of the direction in which the vehicle is traveling. Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings. (Embodiment) FIG. 1 shows an outline of an embodiment of the present invention. A roof panel 20 is attached to a roof 11 of a vehicle 10 so as to be tiltable and slidable. The vehicle 10 is equipped with an outside temperature sensor 31, an outside air humidity sensor 32, and a direct sunlight sensor 35 as outside environment sensors, and an inside temperature (room temperature) sensor 33 and a smoke sensor 34 as inside environment sensors. These are connected to an electrical control unit 40. In addition, humidity sensor 3
No. 2 is installed in a position where water will adhere to the bonnet if it gets wet. 36 is an air conditioner, 37 is an air cleaner, and _Mw is a wiper motor, which are also connected to the unit 40. FIG. 2 shows an electric opening/closing positioning mechanism for tilting and sliding the panel 20. The roof panel 20 is pivotally attached to a carriage 61 by a hinge 60 and supported by one end of a dogleg-shaped lift link 62. A shoe 63 is coupled to the other end of the lift link 62, and this shoe 63 is a guide member above the carriage dozer 61 and is guided so as to be movable in the horizontal direction. A threaded rod connected to the tilt motor M _c is screwed into the shoe 63 .
A pin is set up in the center of the lift link 62, and this pin engages with the guide groove 64. When the motor M _c reverses, the shoe 63 moves to the right and the lift link 62 moves to the right and rotates counterclockwise to close the roof panel 20 (tilt close). When the switch 63 closes the limit switch SW _c1 , the roof panel 20 completely closes the opening of the roof 11 (fully closed). Just before the intermediate pin of the lift link 62 reaches the upper end of the groove 64, the shoe 63 switches the limit switch.
Close SW _c2 . At this time, the panel 20 is fully opened (as shown by the solid line in FIG. 2). Carriage 6
1 is the first guide 65 between the limit switches SW _u1 and SW _u2 in the raised position shown in FIG.
It can be moved left and right along. When the carriage 61 is moved to the left until SW _u2 is closed, the carriage 61 can be lowered into the second guide 66. The carriage 61 is supported by a second lift link 67 having a substantially inverted Z shape. One end of the lift link 67 supports the carriage 61, a second shoe 68 is coupled to the other end, and a pin approximately in the middle of the link 67 engages with a second guide groove 69. A lifting motor Mud is connected to a threaded rod screwed into the shoe 68. When the motor Mud reverses, the shoe 68 moves to the left, and the lift link 67 moves to the left and rotates clockwise to retreat below the second guide 66. When the motor Mud rotates normally, the shoe 68 moves to the right, the lift link 67 moves to the right and rotates clockwise, and comes out above the second guide 66. The carriage 61 is connected to the slide drive wire 7
0, it is driven left and right along the guide 65 or 66. The wire 70 is driven by a slide motor Ms. With the above configuration, the roof panel 20
As shown in Figures 3-3g, it is possible to set any angle (tilt) and opening (slide) from a fully closed state to a fully open state. As will be described later, in this embodiment, in both the automatic opening/closing control and the automatic opening/closing drive by manual switch operation, the roof panel 20 is fully closed (FIG. 3a), tilted and partially opened (FIG. 3b), Tilt fully open (Figure 3c), slide 1/3 open (Figure 3d), slide half open (Figure 3e),
Slide 2/3 open and slide fully open (Figure 3g)
Only seven states can be set. The direct sunlight sensor 35 is installed horizontally on the roof 11, as shown in FIG. 4a. As shown in FIG. 4d, the sensor 35 has four sides 35c, 35d, 35 surrounding the photo sensor 35a.
It has a light-shielding plate formed with numbers e and 35f. As shown in Figure 4b, α is the critical incidence angle of the sun's rays at which direct sunlight passing through the roof opening does not hit the head of the occupant in the rear seat when receiving sunlight from the front, and when receiving sunlight from the rear β is the critical incident angle of sunlight at which direct sunlight does not hit the head of the passenger in the front seat, and as shown in Figure 4c, direct sunlight hits the head of the passenger in the right seat when sunlight is received from the left. Let θ be the critical incident angle at which the sun does not hit the passenger, and γ be the critical incident angle at which the left seat passenger is not hit by sunlight from the right, then α,
The slopes of the sides 35c to 35f are adjusted as shown in FIGS. 4e and 4f so that the photo sensor 35a receives direct sunlight when the incident angle exceeds β, γ, and θ, and does not receive direct sunlight when the incident angle does not exceed β, γ, and θ.
As shown in the figure, they are set to α, θ, β, and γ, respectively. As a result, when the incident angle of sunlight exceeds α, γ, γ, or θ, the photo sensor 35a detects direct sunlight, and as described later, the roof panel 20
Tilt fully open to block direct sunlight (3rd c)
), and when the photo sensor 35a does not detect direct light, the slide is opened (Figs. 3d to 3g).
When the other conditions shown in Fig.) are satisfied, the slide is opened. FIG. 5 shows the configuration of the electric control unit 40.
The electric control unit 40 controls the motors M _c , Mud, Ms
Electrical energizing circuits such as _motor drivers 41 to 44, air conditioning controller 45, and air cleaner driver 46 that energize and Mw; microprocessor (microcomputer) MPU used as an electronic control device; amplifier 47 ₁ 47 ₄ , an amplification/binarization circuit 47 ₅ ; and a 4-channel A/D converter 48, and 25 key switches k ₁₁ to k ₅₅ are connected to the input/output ports of the MPU. Table 1 shows the names of these key switches k ₁₁ to _{k 55} and what they indicate when they are opened or closed. The microprocessor MPU reads the opening and closing of k ₁₁ to _{k 55} at predetermined timing, and then reads the opening and closing of sensors 31 to k 55.
34 detected values are sequentially A/D converted to read digital data, and further ₄₇₅ binary outputs and signal level output registers (flags) of input ports _V1 to _V5 are output.
With reference to the contents of , the opening/closing control of the roof panel 20, driving/stopping of the air cleaner 37, and driving/stopping of the air conditioner 36 are performed in accordance with the set program.

[Table] Figure 6a shows the control operation of the microprocessor MPU. When the microprocessor MPU is powered on (step 100: the word step is omitted in brackets below), it sets all output ports to the non-driving level and clears its internal register (RAM) memory. Initialization is performed, and as one step of this initialization, the positioning state of the roof panel 20 is read and set in a register (flag register) (200). That is, the positioning state is read as shown in Table 2. In Case No. A, B, and D, flags are set for fully open, tilt fully open, and slide fully open, respectively, but in Case No. C, motor M _c is reversely energized until limit switch SW _c1 is closed, and then Set the fully closed flag (after fully closing), and in Case No. E, reversely energize the motor M _c until the limit switch SW _c1 is closed.
Next, the motor M _s is energized to rotate in the normal direction to position the panel 20 with the slide 1/3 open, and then the slide 1/3 open flag is set, and in Case No. F, the limit switch SW _s2 is closed. Energize the motor M _s in forward rotation until the slide is fully open and set the flag to indicate that the slide is fully open.

〔Effect of the invention〕

In the present invention, the light shielding members 35c, 35e, 35
Since the direct solar radiation sensor 35 is used, the photo sensor 35a of the solar radiation sensor 35 is
However, when sunlight is directly shining from the front of the vehicle at an angle α or more, from the rear of the vehicle at an angle β or more, from the right side of the vehicle at an angle γ or more, or from the left side of the vehicle at an angle θ or more, the light On the other hand, the panel opening/closing control means MPU controls the closing drive of the roof panel 20 in response to the detection of the incident light by the photocent 35a, so that no matter what direction the vehicle is facing, (90-α)° toward the front of the vehicle from the line (directly above the center), and toward the rear of the vehicle from the vertical line (90-α)
β)°, (90-γ)° to the left of the vehicle from the vertical line, and (90-θ)° to the left of the vehicle from the vertical line within the conical area formed by the solar irradiation angle. In other words, when strong sunlight directly enters the vehicle interior through the roof panel opening/closing window, the roof panel 20 is automatically closed. Therefore, the shading angle α of the shading member is the critical incident angle of sunlight at which sunlight passes through the roof opening and does not hit the head of the passenger in the rear seat when sunlight is received from the front, and β is the critical incidence angle of sunlight that does not pass through the roof opening and hits the head of the passenger in the rear seat when sunlight is received from the front. Let γ be the critical incident angle of sunlight at which direct solar rays do not hit the head of the passenger in the front seat when receiving sunlight, and γ is the critical incident angle at which direct solar rays do not hit the passenger in the left seat when sunlight is received from the right side. In addition, since θ is set as the critical incident angle at which direct sunlight does not hit the heads of the right seat occupants when sunlight is received from the left, when the roof panel 20 is open, direct sunlight does not hit the heads of any of the above occupants. When there is direct sunlight, the roof panel 20 is automatically closed and the sunlight is blocked or attenuated by the roof panel 20. When the angle of incidence of sunlight is lower than the cone-shaped area, or when the sunlight is weak (for example, on a cloudy day), the roof panel 20 is not driven to close in response to outside light, and the switch operation by the occupant or The roof panel 20 is maintained open in response to the in-vehicle environment sensor. Therefore, the functionality of the roof panel 20 is improved, and the comfort inside the vehicle is improved even when there is strong sunlight or regardless of the direction in which the vehicle is traveling.
