The contact 2b is grounded, and the normally open fixed contact 2c is connected to the power supply 100. When the occupant turns on the lid-close and lid-drift switch 2, the movable contact 2a separates from the normally closed fixed contact 2b and is connected to the normally open fixed contact 2c.

There is.

The full-closed detection switch 5 provided in the controller 4 is a position switch provided at the process end of a sun roof lid (not shown) and has a movable contact 5a connected to a memory means 7 described later. The normally open fixed contact 5b is grounded. The fully closed detection switch 5 is turned on when the sunroof lid is stopped at the fully closed position, the movable contact 5a is connected to the normally open fixed contact 5b, and is turned off and moved when the sunroof lid is separated from the fully closed position. By separating the contact point 5a from the normally open fixed contact point 5b, it has a function of transferring to the memory means 7 a determination signal as to whether or not the sunroof lid is in the fully closed position.

The rectifying means 6 provided in the controller 4 is composed of first, second, third and fourth diodes D1, D2, D3 and D4 for detecting a current direction. The anode of the first diode D1 is connected to the second input terminal 4b, and the cathode side serves as an output stage and is connected to the memory means 7. The anode of the second diode D2 is grounded, and the cathode is connected to the second input terminal 4b. The third diode D3 has an anode connected to the first input terminal 4a, and a cathode connected to the memory means 7 similarly to the first diode D1. The anode of the fourth diode D4 is grounded and the cathode thereof is connected to the first input terminal 4a.

The rectifying means 6 uses the first diode D 1 to supply the current of the power source supplied through the lid open / lid down switch 3 when the lid open / lid down switch 3 is turned on. The detected current is supplied to the memory means 7, and when the lid-close and lid-drift switch 2 is turned on, the power supplied through the lid-close and lid-drift switch 2 is changed. It has a function of detecting a current by the third diode D3 and supplying the detected current to the memory means 7. The second diode D2 and the fourth diode D4 have a function of forming a ground circuit of the controller 4.

The memory means 7 includes a first transistor TR1, a second transistor TR2, a third transistor TR3, a capacitor C1, circuit forming resistors R1, R2, R3, R4, R5 and R6, and diodes D5 and D6. , D7, D8, and a zener diode ZD1 for transistor protection. The first input point A where one end of the resistor R1 and one end of the resistor R2 are connected is connected to the output stage of the rectifying means 6, and the other end of the resistor R2 is fully closed at the second input point B. It is connected to the movable contact 5a of the detection switch 4. The first transistor TR1 is turned on and turned on when the capacitor C1 is charged to a predetermined potential by supplying a current from the first input point A to the capacitor C1 via the resistor R1 and the diode D5. Has a function of cutting the base current of the second transistor TR2. The second transistor TR2 is turned on when the base current is supplied from the first input point A through the resistor R3 and the resistor R5, and sets the anode side of the diode D5 connected to the collector to the low level. Have a function. The third transistor TR3 is turned on when a base current is supplied from the first input point A through the resistor R3, the diode D7, and the resistor R6, and when turned on, forms a conduction path in the relay coil 8a of the driving means 8. It has a function to do.

In the memory means 7, when the sunroof lid reaches the fully closed position, the fully closed detection switch 5 is on and the movable contact 5a is connected to the normally open fixed contact 5b. The other end of the resistor R2 and the anode of the diode D6 are grounded by the grounding of the input point B. When the second input point B is grounded, the switch 3 for lid open / lid down is turned on and When power is applied to the first input point A through the two input terminals 4b and the first diode D1 of the rectifying means 6, the capacitor C1 is connected from the first input point A through the resistor R1 and the diode D5. The first transistor TR1 is kept off by supplying the base current to the second transistor TR2 via the first input point A, the resistor R3, and the resistor R5 earlier than the current supply. Then, the second transistor TR2 is turned on, and the base current is supplied from the first input point A to the third transistor TR3 through the resistor R3, the diode D7, and the resistor R6. The relay coil 8a of the drive means 8 is excited by recognizing that the TR3 is turned on and the lid open / lid down switch 3 is turned on after the fully closed detection switch 5 is turned on.

The memory means 7 includes a second input point B and a diode when the sunroof lid is separated from the fully closed position and the fully closed detection switch 5 is turned off by turning on the lid open / lid down switch 3. Since the potential of the power supply 100 is applied to the anode of D6 via the resistor R2, current is supplied to the capacitor C1 via the first input point A, the resistor R2, and the diode D6, and the capacitor C1 starts charging. Then, when the charging potential of the capacitor C1 reaches a predetermined value, the base current is supplied to the first transistor TR1, so that the first transistor TR1 is turned on and the first transistor TR1 is turned on to turn on the first input. The base current supplied to the third transistor TR3 via the point A, the resistor R3, the diode D7 and the resistor R6 is However, since the base current is generated in the third transistor TR3 through the first input point A, the resistor R2, the second input point B, the diode D8, and the resistor R6, the third transistor TR3 is turned on. By holding the state, it is recognized that the lid open / lid down switch 3 is turned on when the full close detection switch 5 is not turned on, and the energizing path of the relay coil 8a of the drive means 8 is recognized. It keeps forming and continues to excite.

The memory means 7 is mechanically prevented from moving when the sunroof lid reaches the fully open position, and when the lid open / lid down switch 3 is turned off, power is applied to the first input point A. Since the third transistor TR3 is turned off, the relay coil 8a is recognized by recognizing that the lid open / lid down switch 3 is turned off in a state in which the fully closed detection switch 5 is not recognized to be on. Cut the energization path of.

In the memory means 7, when the lid open / lid down switch 3 is turned off and then the lid close / lid lift switch 2 is turned on in a state where the sunroof lid has reached the fully open position, Since the potential of the power supply 100 is applied to the first input point A, current is supplied to the capacitor C1 via the resistor R2, the second input point B, and the diode D6, and the first potential is supplied to the capacitor C1 according to the charging potential of the capacitor C1. The first transistor TR1 is turned on and the anode of the diode D7 is grounded, so the second transistor TR2 is turned off, but the third transistor TR3 is connected to the first input point A, the resistor R2 and the second input point. Since the base current is supplied via B, diode D8 and resistor R6, it is turned on and the full-closed detection switch 5 is turned on without being recognized. By recognizing that the switch 2 for lid close and lid drift has been turned on, the energization path of the relay coil 8a is formed.

When the sunroof lid reaches the fully closed position and is mechanically prevented from moving, the fully closed detection switch 5 is turned on, so that the anode of the diode D6 is grounded. As a result, the base current of the third transistor TR3 is cut off, and the first transistor TR1 supplied with the base current from the first input point A through the resistor R1, the diode D5, and the resistor R4 maintains the ON state. Therefore, the ground of the anode of the diode D7 is maintained, the capacitor C1 is discharged through the resistor R4 and the first transistor TR1, and the lid closing / lid drift switch 2 is turned off by turning off the third transistor TR3. In the ON state, the fact that the fully closed detection switch 5 is turned on is recognized, and the energization path of the relay coil 8a is cut off.

The memory means 7 receives the second input when the sunroof lid reaches the fully closed position and the lid closing / lid drift switch 2 is turned off and then the lid closing / lid drift switch 2 is turned on. Since the point B is grounded and the potential of the power source 100 is applied to the first input point A, the base current via the first input point A, the resistor R3, and the resistor R5 is faster than the current supply to the capacitor C1. Since the second transistor TR2 is supplied to the second transistor TR2, the second transistor TR2 is turned on, the anode of the diode D5 is grounded, and the anode of the diode D6 is also grounded. Therefore, the first transistor TR1 is not turned on. The third transistor TR3 to which the base current is supplied via the first input point A, the resistor R3, the diode D7 and the resistor R6 is turned on. Therefore, the full-closed detection switch 5 is turned on, and it is recognized that the lid-close and lid-drift switch 2 is turned on to form an energization path for the relay coil 8a.

The memory means 7 is turned off after the sunroof lid has reached the fully closed position and the lid close / lid drift switch 2 is turned on, and the lid open / lid down switch 3 is turned on. Then, since the second input point B is grounded and the potential of the power supply 100 is applied to the first input point A, the first input point A, the resistor R3, and the resistor R5 are connected earlier than the current supply to the capacitor C1. Since the base current via the second transistor TR2 is supplied to the second transistor TR2 and the second transistor TR2 is turned on, the anode of the diode D5 is grounded, and the anode of the diode D6 is also grounded. The third transistor TR 3 is not turned on and is supplied with the base current via the first input point A, the resistor R3, the diode D7, and the resistor R6. Is turned on, the full-closed detection switch 5 is turned on, and it is recognized that the lid open / lid down switch 3 is turned on to form an energization path for the relay coil 8a.

On the other hand, the driving means 8 is composed of a relay coil 8a, a movable contact 8b, and a normally open fixed contact 8c. The driving means 8 has one of the relay coils 8a provided in the memory means 7 for supplying power. The relay coil 8a is connected to the line 7a and the other end of the relay coil 8a is connected to one of the transistor protection Zener diode ZD1 of the memory means 7 and the collector of the third transistor TR3. Further, in the driving means 8, the movable contact 8b is connected to the first output terminal 4e of the controller 4, and the normally closed fixed contact 8c is connected to the second output terminal 4f of the controller 4 via the second power supply line 4d. The normally open fixed contact 8d is connected to the first power supply line 4c.

Since the relay coil 8a is excited by turning on the third transistor TR3 of the memory means 7, the driving means 8 changes the movable contact 8b from the normally closed fixed contact 8c to the normally open fixed contact 8d. It has a function of switching and connecting the first input terminal 4a to the first output terminal 4e through the first power supply line 4c.

In the sunroof motor control device 1 having such a structure, when the lid open / lid down switch 3 is turned on by an operation of an occupant when the sunroof lid is at the fully closed position, the memory means is operated. In the state where the second input point B of 7 is grounded, the potential of the power supply 100 is applied to the first input point A through the second input terminal 4b of the controller 4 and the first diode D1 of the rectifying means 6. Therefore, the relay coil 8a is energized by forming an energization path, and the movable contact 8b is separated from the normally closed fixed contact 8c and connected to the normally open fixed contact 8d, so that the second input terminal 4b and the second The output terminal 4f, the other brush terminal 9b of the sunroof motor 9, one brush terminal 9a of the sunroof motor 9, the first output terminal 4e, the first input terminal 4a, and the power supply 10 to ground. Since a current of 0 flows, the motor shaft 9c provided in the sunroof motor 9 rotates forward, and the motor shaft 9c rotates forward, so that the sunroof lid is connected via a sunroof slide mechanism (not shown) connected to the motor shaft 9c. Move toward the fully open side.

When the sunroof lid is moved to the fully open position by turning on the switch 3 for lid open and lid down, the sunroof lid is mechanically prevented from moving at the fully open position, and the switch 3 for lid open and lid down is operated. When the third transistor TR3 is turned off by being motivated to turn off, the energization path of the relay coil 8a is cut, so that the current supply to the sunroof motor 9 is stopped and the rotation of the motor shaft 9c is stopped. Stop the lid in the fully open position.

When the lid closing / lid drift switch 2 is turned on by an operation of an occupant when the sunroof lid is at the fully open position, the controller is operated in a state where the second input point B of the memory means 7 is not grounded. Since the electric potential of the power supply 100 is applied to the first input point A via the first input terminal 4a of No. 4 and the third diode D3 of the rectifying means 6, the relay coil 8a is excited by forming a conduction path. , The movable contact 8b is separated from the normally closed fixed contact 8c and connected to the normally open fixed contact 8d, so that the first input terminal 4a, the first output terminal 4e, one brush terminal 9a of the sunroof motor 9, and the sun roof Since the current of the power supply 100 flows to the other brush terminal 9b, the second output terminal 4f, the second input terminal 4b, and the ground of the motor 9, the motor provided in the sunroof motor 9 is equipped. The sun shaft lid is rotated in the reverse direction, and the motor shaft 9c is rotated in the reverse direction to move the sunroof lid toward the fully closed side.

When the sunroof lid reaches the fully closed position by turning on the lid closing and lid down switch 2, the sunroof lid is mechanically prevented from moving and the fully closed detection switch 5 is turned on. The third transistor TR3 of No. 7 is turned off to stop the formation of the energization path of the relay coil 8a, so that the current supply to the sunroof motor 9 is stopped and the sunroof lid is stopped at the fully closed position.

When the sunroof lid is stopped in the fully closed position and the lid closing / lid down switch 2 is turned off, the lid opening / lid drift switch 3 is turned on by the occupant. The detection switch 5 is in the ON state, and when the third transistor TR3 of the memory means 7 is turned on, the relay coil 8a is energized by forming an energization path, and the movable contact 8b is separated from the normally closed fixed contact 8c. Since it is connected to the normally open fixed contact 8d, the second input terminal 4b, the second output terminal 4f, the other brush terminal 9b of the sunroof motor 9, the one brush terminal 9a of the sunroof motor 9, and the first output Since the current of the power source 100 flows to the terminal 4e, the first input terminal 4a, and the ground, the motor shuffle provided in the sunroof motor 9 is equipped. When the motor 9c rotates in the forward direction and the motor shaft 9c rotates in the forward direction, the rear portion of the sunroof lid is moved upward through a lid drift mechanism (not shown).

When the lid closing and lid down switch 3 is turned on by the occupant while the sunroof lid is in the lifted state, the fully closed detection switch 5 is in the on state, and the third closing of the memory means 7 is performed. When the transistor TR3 of is turned on, the relay coil 8a is excited by forming an energization path, and the movable contact 8b is separated from the normally closed fixed contact 8c and connected to the normally open fixed contact 8d. Terminal 4a, first output terminal 4e, one brush terminal 9a of sunroof motor 9, other brush terminal 9b of sunroof motor 9, second output terminal 4f, second input terminal 4b, power supply 100 to ground Since the electric current flows in, the motor shaft 9c provided in the sunroof motor 9 rotates in the reverse direction, and the motor shaft 9c rotates in the reverse direction. The rear side portion of the sunroof lid is moved downward through the lid drift mechanism.

During this time, the controller 4 turns on and off the lid-open / lid-close switch 3 and the lid-close / lid-drift switch 2 so that the current detected by the rectifying means 6 is stored in the memory means. The energization path of the drive means 8 is formed based on the turn-on sequence of the switches recognized by the reference numeral 7, and current is supplied to the sunroof motor 9.

[0034]

As described above, since the sunroof motor control device according to the present invention has the above-mentioned configuration, the forward and reverse currents detected by the rectifying means are recognized by the memory means. Since the energization path of the driving means is formed based on the ON order of the switches, and the current can be supplied to the sunroof motor, the wiring between the first switch, the second switch and the controller is the first switch. Since it suffices to flow the current flowing from the second switch to the rectifying means, it is possible to control the current supply to the sunroof motor without pulling a large number of lines, and to control the switch and controller. It has an excellent effect that the number of wires can be reduced by connecting the wiring between the wiring and the wiring with extremely simple wiring.
