Abstract

PURPOSE:To reduce a window slop noise caused by a roof oping without installing a deflector, by varying the opening of a roof panel according to a variation in speed of a car. CONSTITUTION:Each detection signal out of a car speed detector 2 detecting a car speed and an opening detector 3 detecting the opening of a roof panel 6 is inputted into an opening control device 1 controlling the opening of the roof panel 6. Here, for example, a speedometer for a car is utilized for the car speed detector and as for the opening detector 3, a displacometer is used. In addition, the opening control device 1 is made to store an opening setting value of the roof panel 6 corresponding to the car speed, while the signal outputted on the basis of this setting value is inputted into an on-off operation device 4. Thereupon a roof panel driving device 5 drives and controls the roof panel 6 to accord with the opening set up according to the car speed via a lonk mechanism 9.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a μmm tongue closing device that reduces wind slob noise by changing the opening degree of the roof panel depending on the vehicle speed. .

(Prior art) When a vehicle is driven with its roof open, the wind flowing in from the direction of travel collides with the air inside the vehicle, creating turbulence.
A windthrob sound is produced by a whistle-like phenomenon. Conventionally, in order to avoid the above-mentioned phenomenon, it is known that a deflector is installed on the roof of the vehicle to deflect the wind upwards to reduce the sloping noise, but this technology has the disadvantage of a complicated structure. are doing.

By the way, as shown in the graph in Figure 6, the slob noise increases rapidly as the vehicle speed increases, but after reaching a peak, it rapidly decreases, and after that, even if the vehicle speed increases, the slob noise remains almost flat. becomes. In addition, the opening area of the roof spring μ (
As the aperture length) decreases, the slob noise also decreases, and the vehicle speed at which the slob noise peaks differs depending on the aperture length. This indicates that by changing the opening degree of the Lou-7 panel in accordance with the vehicle speed, it is possible to reduce the slob noise to an acceptable range without making full use of the roof's function.

In addition, as for changing the opening degree of the roof spring μ,
A μmm tube panel closing device that changes the opening degree of the roof panel according to changes in the environment such as the amount of cigarette smoke and room temperature was developed in Japanese Patent Laid-Open No. 58.
Although it has been proposed in Japanese Patent No. 191628, no measures against sloping noise have been taken.

(Purpose of the Invention) This invention was made to solve the above-mentioned conventional problems, and focuses on the relationship between vehicle speed and the opening degree of the roof spring μ, and changes the opening degree of the roof spring according to changes in vehicle speed. Accordingly, it is an object of the present invention to provide a roof panel opening/closing device in which the slobbing noise caused by the opening of the μ-f is reduced.

(Structure of the Invention) The structure of this invention for achieving the above object is shown in FIG.

In Figure 1, the opening degree of the μm flap (
Detection signals from a vehicle speed detection device 2 that detects the vehicle speed and an opening detection device 3 that detects the opening of the roof spring μ are input to the opening control means 1 that controls the opening (opening length). As the vehicle speed detection device 2, for example, a speedometer of the vehicle can be used, while as the opening degree detection device 3, a displacement meter can be used.

The opening control means 1 stores a roof spring μ opening value (hereinafter referred to as a set value) set in accordance with the vehicle speed 9, and based on the detection signal from the vehicle speed detection device 2,
Find the opening setting value according to the vehicle speed. The signal output based on this set value is input to the opening/closing operation means 4,
The opening/closing operation means 4 drives and controls the roof panel driving means 5 so as to change the opening degree of the roof spring μ to a preset opening position according to the vehicle speed.

(Example) An example of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view of an automobile equipped with a μm roof spring opening/closing device, and FIG. 3 is an enlarged sectional view taken along the line T in FIG. 2, showing the opening/closing operation of the roof spring μ6.

In FIG. 2, the sliding roof panel 6 attached to the vehicle body 70 roof 8 is 1. The opening/closing operation is performed along the guide tray /I/ (not shown) by driving the roof panel driving means 5 consisting of a motor via the linkage mechanism 9. In FIG. 2, lO, , 11 are manual switches, 10 is a roof closing switch, and 11 is a roof closing switch.

Further, FIG. 4 is a system diagram showing the circuit of the present invention, in which the opening degree control means 1 controls the opening degree h (setting fii) of the roof panel 3 corresponding to the vehicle speed by, for example, a microcomputer. It is provided with a memory 12 for storing information, and a comparison means 13 for comparing the actual value obtained based on the detection signal from the opening degree detection device 3 and the set value.

Since the roof spring 1/6 shown in FIG. 2 is provided to open the roof 8 of the vehicle body 7, the above-mentioned opening setting value shown in FIG. long)
is set to . However, if priority is given to reducing the sloping sound, the above setting value may be lowered.

On the other hand, as the vehicle speed detection device 2, a speedometer of the vehicle is used, and as the opening degree detection device 3, a displacement meter is used. As this displacement meter, for example, a meter can be used in which a resistor is attached to a guide tray μ that guides the roof spring 1v5i, and a change in the position of the roof spring μ6 is detected as a change in resistance value.

Further, the opening/closing operation means 4 includes a μm closing movement circuit 14 that drives the roof panel driving means 5 in the direction of closing the roof spring /L/6, and a roof opening movement circuit that drives the roof panel driving means 5 in the direction of opening the roof spring μ6. It consists of 15.

Reference numeral 16 denotes an OR circuit, into which signals are inputted from the comparison means 13 of the opening control means 1 and the roof closing switch 11 of the manual switch, and the output signal thereof is inputted to the roof closing operation circuit 14.

17 is an AND circuit, into which signals are input from the comparison means 13 and the manual switch roof closing switch 10;
The output signal is input to the roof opening circuit 15. 18
is a NOT circuit, and the input from the comparison means 13 to the AND circuit 17 is performed via the NOT circuit 18 of and.

Next, the operation of the above configuration will be explained. The detection signal from the vehicle speed detection device 2 is input to the memory 12 of the opening degree control means 1, and the set value of the opening degree corresponding to the vehicle speed is taken out from the memory 12. This set value and the detection signal from the opening detection device 3 are input to the comparison means 13 and compared, and if the actual measured value exceeds the set value, an H level signal is sent to operate the μm valve closing circuit 14. Output. This H level signal is O
The signal is inputted to the roof closing circuit 14 through the R circuit 16, and the roof closing circuit 14 is operated. In this case, even when the roof closing switch 11 is turned on, an H level signal is output from the roof closing switch 11, and the OR circuit 16
The roof closing circuit 14 is actuated through the roof closing circuit 14. Claw 9: When the driver wishes to close the roof spring A/ due to a drop in the temperature inside the vehicle, noise outside the vehicle, etc., the roof closing circuit 14 is activated by the roof closing switch 11 alone.

On the other hand, if the actual measurement value is less than the set value, the comparator 13 outputs an L level signal, which is inverted to H level by the NOT circuit 18 and then input to the AND circuit 17 . At this time, only when the μmm opening/opening switch 10 is turned on and an H level signal is output from the roof closing switch 10, an H level signal is output from the AND circuit 17, and μmm
The m-opening circuit 15 is activated. In other words, the μm opening operation circuit 15 operates only when the driver's intention and the judgment of the opening degree control means 1 match.

Next, the set value of the opening degree will be explained with reference to FIG. For example, if the vehicle speed at which the slob noise peaks at aperture length A is 1, if the opening degree (aperture length) is set to B, which is smaller than A, the slob noise peak at aperture length B will be at vehicle speed V. , the slob noise decreases rapidly at vehicle speed ■l. Therefore, this opening length B can be used as the set value of the opening degree at vehicle speed 1. Similarly, at a vehicle speed of 8, the set value can be set to the opening length C, which is also smaller than the opening length B.

Next, the operation of the opening control means 1 will be explained according to the flowchart shown in FIG. In the same figure, P1 to PIO
indicates each step.

Starting at P1, at P2, the actual measured values of the vehicle speed and the opening degree of the μm door panel are read based on the detection signals from the vehicle speed detection device 2 and the opening degree detection device 3 shown in FIG. Fifth
At P3 in the figure, it is determined whether the roof close switch 10 and the roof close switch 11 in FIG. 4 are OFF. If both are OFF, the set value of the opening degree corresponding to the vehicle speed is read in P4 of FIG. 5, and it is determined in P5 whether the measured value of the roof panel opening degree is less than the set value. If it is below, the control operation returns to P2, and if it is not below, μm at P6.
The m tube is driven in the direction of closure.

On the other hand, if the roof close switch 10 or the roof close switch 11 in FIG. 4 is not OFF at P3, P1 in FIG.
Then, it is determined whether the roof closing switch 10 is ON.

If the roof closing switch 10 is not ON, that is, if the roof closing switch 11 is ON, the roof panel is driven to close at P6.

Also, if the roof close switch 10 is ON at Pl, P
In step 8, the set value of the roof panel opening degree corresponding to the vehicle speed is read, and in step P9, it is determined whether the actual value of the roof panel opening degree is less than the set value. If it is below, the roof panel is driven in the opening direction at PIO, whereas if it is not, the control operation returns to P2.

(Effects of the Invention) As described above, according to the present invention, wind throb noise can be effectively reduced by changing the opening degree of the μm flap according to changes in vehicle speed. Furthermore, the structure is simple because it is not necessary to provide all stages of the deflector.
