Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle sunroof opening / closing control device.

[0002]

2. Description of the Related Art As a vehicle sunroof, for example, FIG.
As shown in FIG. 1, an opening 107 formed in a roof 103 of a vehicle 101 is slidably opened and closed by a lid panel 105 driven by a driving device (not shown).
In a state where the lid panel 105 of the vehicle 101 is fully opened or set at a position close to the fully opened state, approximately 40
When the vehicle travels at a speed of up to 60 km / h, the airflow S flows into the vehicle interior from the opening 107, and noise is often generated. The inflow of the airflow S is a phenomenon of a large sound pressure level called “wind throb”, and the cause of the occurrence is said to be the entrainment of the airflow S in the opening 107.

As a countermeasure, it has been proposed to provide a deflector made of a thin plate at the front edge of the opening to rectify the airflow over the opening, thereby preventing the inflow of the airflow.
Such a deflector is provided so as to be capable of falling in conjunction with opening and closing of the lid panel. When the lid panel is opened, the deflector is in an upright state. In such an upright state, the deflector is held by a biasing force of a spring. ing. Then, the deflector is attached in a posture inclined rearward, and when the lid panel is opened and the vehicle travels at the above-described speed, the airflow hitting the deflector from the front is raised in a direction along the inclined surface. Later, it descends while drawing a large arc above the opening, so that it is designed to flow backward without flowing into the vehicle interior.

[0004]

However, the airflow that hits the deflector from the front surface rises in the direction along the inclined surface and then descends above the opening, so if the front-back length of the opening is long, There is a risk that the airflow will flow in from the rear of the opening. To prevent the inflow of airflow, operate the closing switch on the sunroof to close the lid panel, move it to the position where airflow does not flow, and stop the lid panel each time to prevent the inflow of airflow. The operation must be performed, and it is troublesome to repeat such an operation.

Further, since the deflector keeps its upright state by the biasing force of the spring, if the spring degrades its elastic force due to aging, the deflector receiving the air current cannot be supported and tilts, causing the air flow to fall. There is a possibility that the function of preventing the inflow into the opening cannot be sufficiently performed.

Therefore, the present invention can easily prevent the airflow from flowing into the vehicle compartment when the airflow reaches a predetermined vehicle speed at which the airflow flows into the opening while the sunroof is running in a fully opened state or a position near the fully opened state. It is an object of the present invention to provide a control device for a vehicle sunroof that can be operated and does not require a deflector.

[0007]

According to the first aspect of the present invention,
An opening and closing control device for a vehicle sunroof that slides and opens an opening formed in a roof of a vehicle by a lid panel driven by a driving device, the vehicle having a vehicle speed sensor capable of detecting a speed of the vehicle, wherein the vehicle has a lid panel When the vehicle speed sensor detects a predetermined vehicle speed while the vehicle is traveling in a fully open state or a position close to full open, the lid panel is moved to a predetermined position set in the closing direction.

According to the first aspect of the invention, the lid panel is set to the closing direction when the airflow reaches a predetermined speed at which the airflow flows into the opening portion of the sunroof while the vehicle is traveling in a fully opened state or a position near the fully opened state. Since the lid panel is moved to the predetermined position, the lid panel prevents the airflow from flowing into the vehicle interior, so that the occurrence of windslob can be prevented, the noise in the vehicle interior can be prevented, and the comfort can be improved.

Since a deflector becomes unnecessary and the number of parts can be reduced, a sunroof having a simple structure and a low cost can be obtained.

When the vehicle speed sensor reaches a predetermined speed, the lid panel is moved to a predetermined position set in the closing direction, so that a troublesome operation is not imposed on the occupant and the operation is simple.

According to a second aspect of the present invention, there is provided a holding circuit for holding the stopped state even if the vehicle speed sensor detects a predetermined vehicle speed again after the lid panel moves to a predetermined position and stops. It is characterized by the following.

According to the second aspect of the present invention, even if the vehicle speed sensor repeats ON and OFF in accordance with the increase and decrease of the vehicle speed, the lid panel which once moves and is in the stopped state is held in the stopped state by the holding circuit. Therefore, the lid panel does not repeatedly open and close according to the increase or decrease of the vehicle speed, so that the battery can be prevented from being consumed and the amount of noise generated by the motor can be reduced.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a sunroof according to the present invention. FIG. 2 is a schematic sectional view taken along the line II-II in FIG. FIG. 3 is a circuit diagram of the control device of the present invention.

In FIG. 1, an opening 7 of a sunroof 5 is formed in a roof 3 of a vehicle 1. The opening 7 of the sunroof 5 is opened in a substantially rectangular shape on the upper surface of the roof 3 with the short side as the running direction, and a slidable lid panel 9
It is opened and closed by. Opening and closing the lid panel 9
This is performed by rotating the motor 11 as a driving device forward and backward.

FIG. 3 shows the control circuit 12 of the present invention. On the input side of the main control unit 13, a mode changeover switch 15, a vehicle speed sensor 17, a rotary encoder 19 as a position detecting means, a reset switch 21, a teaching switch 23, and an open operation switch 25 for opening and closing the sunroof 5 in a manual mode. And the closing operation switch 27 are connected respectively.

The mode changeover switch 15 is used for the automatic mode 1
5a, manual mode 15b, automatic mode 15
By switching to "a", the lid panel 9 can be moved to a predetermined position set in the closing direction (hereinafter, referred to as "automatic movement") in conjunction with the detection of the predetermined vehicle speed detected by the vehicle speed sensor 17. When the mode changeover switch 15 is switched to the manual mode 15b, the mode becomes a normal sunroof operation mode, and the automatic movement is not performed.

The vehicle speed sensor 17 detects the traveling speed of the vehicle 1, and turns ON when a predetermined vehicle speed is detected. The predetermined vehicle speed is a speed at which the airflow S generated by traveling flows into the vehicle interior from the opening 7 of the sunroof 5 and is set to be approximately 40 to 60 km / h. Since it differs depending on the shape of the opening 7, it is determined experimentally and set.

The rotary encoder 19 includes a motor 11
And a pulse signal corresponding to the movement of the lid panel 9 is input to the main control unit 13.

The reset switch 21 is a normally open switch. When the reset switch 21 is turned on, a holding state of a holding circuit 31 described later is canceled, and when the vehicle speed sensor 17 detects a predetermined vehicle speed again, automatic movement can be started. State.

The teaching switch 23 is a normally open switch, and has a lid panel 9 in which no wind throb occurs.
In the manual mode 15b, the optimal position of the stop position storage circuit 33 is checked by turning on the teaching switch 23.
Is input and stored.

On the other hand, a motor 11 is connected to the output side of the main controller 13 so as to be able to rotate forward and reverse. The control of the forward / reverse rotation of the motor 11 is performed by a drive circuit 35 in the main control unit 13.

In the automatic mode 15a, the lid panel 9
While the is moving, a chime 29 sounds to warn the occupant.

In the main controller 13, a holding circuit 31, a stop position storage circuit 33, and a drive circuit 35 for driving the motor 11 are provided.

When the lid panel 9 has completed the automatic movement and is stopped, the holding circuit 31 detects the vehicle speed sensor 17.
Functions to keep the drive circuit 35 stopped so that it does not move automatically even when the predetermined vehicle speed is detected again.

The stop position storage circuit 33 includes the teaching switch 2
The position data from the rotary encoder 19 when 3 is turned on is stored as a predetermined position. The stored data is compared with the position data detected by the rotary encoder 19 when the lid panel 9 automatically moves, and when the two data match, it is determined that the predetermined position has been reached, and the automatic movement is performed. Stopped.

Next, the operation of the present embodiment will be described.

First, a procedure for storing a predetermined position in the stop position storage circuit 33 prior to the automatic movement of the lid panel 9 will be described. Mode switch 15 before running the vehicle
Is switched to the manual mode 15b, and the vehicle 1 is driven with the sunroof 5 fully opened. At the vehicle speed at which the wind throb occurs, the airflow S starts to flow into the vehicle interior from the opening 7. At this time, by operating the closing operation switch 27,
The lid panel 9 is moved from the opening 7 to a position where the airflow S does not flow, and stopped. In order to set this position to a predetermined position at the time of automatic movement, the teaching switch 23 is turned on to store the position data in the stop position storage circuit 33.

Next, the automatic driving mode will be described. Vehicle 1
Mode switch 15 before running
Switch to. This completes the preparation for the automatic movement of the lid panel 9 and waits for a signal from the vehicle speed sensor 17.

Next, when the vehicle 1 is run with the sunroof 5 fully opened, the rotary encoder 19 detects the fully open position, but the vehicle speed sensor 17 has not yet reached the predetermined vehicle speed. Has become. At this time, no output is performed from the main control unit 13 to the motor 11.

When the running speed of the vehicle gradually increases and reaches a predetermined vehicle speed, the vehicle speed sensor 17 is turned on. Detection of fully open position of rotary encoder 19 and vehicle speed sensor 1
When the condition that the switch 7 is turned on is satisfied, the main controller 13 outputs a drive signal to the motor 11 to move the lid panel 9 in the closing direction. When the drive signal is output, the motor 11 rotates to move the lid panel 9 in the closing direction. When the lid panel 9 moves in the closing direction, the rotary encoder 1
9 continues to detect the position data of the lid panel 9. Here, when the position data detected by the rotary encoder 19 matches the storage data stored in the stop position storage circuit 33, the main control unit 13 stops outputting to the motor 11, and the lid panel 9 stops at a predetermined position.

The predetermined position differs depending on the type of vehicle.
The distance from the fully open position ranges from about 50 mm to about half of the length of the opening 7 in the front-rear direction.

During the movement of the lid panel 9 to a predetermined position, the chime 29 continues to sound.
Warn occupants that they are moving automatically.

When the mode changeover switch 15 is switched to the manual mode 15b and the open operation switch 25 is operated to open the lid panel 9, the lid panel 9 is set to stop at a predetermined position. In the case where the opening operation is continuously performed to the fully opened position, once the user releases his / her hand and operates the opening operation switch 25 again, the lid panel 9 moves toward the fully opened position.

In the state where the lid panel 9 is stopped at a predetermined position in this way, even if the air flow S descends as shown in FIG. Since it is covered, the airflow S is prevented from flowing into the vehicle interior from the opening 7.

After the lid panel 9 stops at a predetermined position in the automatic mode 15a, the vehicle speed increases and decreases, so that even if the vehicle speed sensor 17 repeats ON / OFF, the holding circuit 31
Thus, the stopped state is maintained, and the lid panel 9 is not automatically moved. Therefore, the lid panel 9 does not repeatedly open and close according to the increase or decrease of the vehicle speed, so that the battery is prevented from being consumed and the noise generated by the motor 11 is reduced.

When the vehicle runs at a predetermined vehicle speed or higher, the airflow S flows behind the opening 7, so that the airflow S does not flow into the vehicle interior from the opening 7, and there is no possibility that a wind throb is generated. In such a case, when the reset switch 21 is turned on, the holding circuit 31 is cancelled, the lid panel 9 moves to the fully open position, and a large open feeling is obtained. Thereafter, when the vehicle speed of the vehicle 1 decreases to a predetermined vehicle speed, the lid panel 9 automatically moves to a predetermined position, thereby preventing the occurrence of the wind throb.

[0038]

According to the first aspect of the present invention, when the vehicle reaches a predetermined vehicle speed at which the airflow flows into the opening of the sunroof during traveling in the fully open state, the lid panel is set to the predetermined position in the closing direction. Therefore, the lid panel can prevent the airflow from flowing into the vehicle interior, thereby preventing the occurrence of wind slops and preventing noise in the vehicle interior to improve comfort.

Further, since a deflector becomes unnecessary and the number of parts can be reduced, a sunroof having a simple structure and a low cost can be obtained.

When the vehicle speed sensor reaches a predetermined speed, the lid panel is moved to a predetermined position set in the closing direction, so that a troublesome operation is not imposed on the occupant and the operation is simple.

According to the second aspect of the present invention, even if the vehicle speed sensor repeatedly turns ON and OFF according to the increase and decrease of the vehicle speed,
The lid panel, which has been moved and then stopped, is held in a stopped state by the holding circuit, so the lid panel does not repeatedly open and close as the vehicle speed increases and decreases, preventing battery consumption and generating motors. The amount of noise generated can be reduced.
