Abstract

PROBLEM TO BE SOLVED: To prevent a traveling impossible state accompanying failure of closing action of an opening/closing body and occurrence of a burglary by forming a control means to control the opening/closing body in a manner that when an opening signal is inputted, the control means previously determines the normal or abnormal condition of a closing side control circuit, and in the case of the abnormal condition, the control means prohibits the opening control of the opening/closing body based on the opening signal. SOLUTION: DC voltage of a battery 1 is supplied to a microcomputer 11 in a control circuit 15. When a closing switch or opening switch 6 in a control box 4 is closed, a signal is inputted to the microcomputer 11 through an input circuit 9 or 10, operation result is outputted to an output circuit 13 according to input of the signal to the microcomputer 11, electric power is supplied to a motor 16, and an opening part is closed or opened. When a power supply switch is inputted, existence of the opening signal is checked, and if there is no opening signal, opening control is performed and also cancellation of shift lock is prohibited. In the case that the opening signal may exit and the closing switch is failed, opening control is prohibited, and failure is informed. A traveling impossible state accompanied by the closing failure of the opening/closing body and occurrence of burglary can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing control apparatus for an opening / closing body for a motor vehicle, and more particularly, to an opening / closing body control apparatus for a vehicle in which various safety measures are taken. The present invention relates to preventing the occurrence of a theft or the like due to a state in which the vehicle cannot travel or an open state is maintained.

2. Description of the Related Art Conventionally, there are various types of opening / closing control devices for a vehicle-mounted opening / closing body such as a door having a vertical axis or a horizontal axis hinge, a window glass, a slide door, a roof door having a horizontal axis hinge, a roof slide door, and a roof slide glass. Equipped with safety mechanism. For example, an electric window glass regulator with a temporary stop mechanism to prevent the infant from being pinched by a part of the body, the automatic transmission cannot enter the D range or the R range and cannot run when the sliding door and the roof door are open. Safety mechanism. Further, a switch having a double switch is also known. However, on the other hand, these safety mechanisms still have no problem, and for example, have the following problems. That is, a vehicle cannot be driven due to a closing operation failure of the opening / closing body, or an in-vehicle product or a vehicle itself is stolen due to holding the open state due to the inability to close. Then, the present inventor came up with the idea that, as a means for solving these problems, if the closure of the opening / closing body was first confirmed, the opening / closing body itself would not be opened.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an on-vehicle opening / closing body control device in which various safety measures are taken. Is to prevent the occurrence of.

According to the present invention, there is provided an opening / closing control apparatus for an automotive opening / closing body for opening / closing an on-vehicle opening / closing body, an opening / closing switch for instructing opening / closing of the opening / closing body, control means for controlling the opening / closing body, and opening of the opening / closing switch. An open-side transmitting circuit for transmitting a signal to the control means; and a closing-side transmitting circuit for transmitting a closing signal of a closing switch to the control means. Alternatively, an opening / closing control apparatus for a vehicle opening / closing body is configured to determine an abnormality and to prohibit opening / closing of the opening / closing body based on the opening signal when the closing side control circuit is abnormal. Item 1) The opening / closing control device (Claim 2) according to Claim 1, wherein the opening / closing member or the opening / closing control device includes a prohibition mechanism that prohibits the running of the vehicle when the opening / closing member is opened.
The opening / closing control device (Claim 3) according to any one of claims 1 and 2, wherein the opening / closing body is a window glass. The roof opening / closing body opens and closes by swinging an opening provided on a roof upper surface around a horizontal axis. An opening / closing control device according to claims 1 to 3 (claim 4) is provided. Hereinafter, the present invention will be described in detail with reference to Examples.

FIG. 2 is a circuit diagram of an embodiment, FIG. 3 is a circuit diagram of another embodiment, and FIG. 1 is a flowchart showing the operation of the embodiment. 2 and 3, reference numeral 1 denotes a battery, 2
Is a fuse, 3 is a power switch, 4 is an operation box, 5 is a close switch, 6 is an open switch, 8 is a power circuit, 9, 10
Is an input circuit, 11 is a microcomputer, 13 is an output circuit, 15 is a control device, 16 and 17 are motors, 20 is a close detection switch, 21 is a middle open detection switch, 22 is a fully open detection switch, and 30 is a P range detection. The switch 33 is a shift lock solenoid. First, in FIG.
A DC voltage is supplied from the battery power source 1 to the control device 15 via the fuse 2 and the power switch 3.
It is supplied to the microcomputer 11 via a power supply circuit composed of a DC converter. On the other hand, when the closing switch 5 or the opening switch 6 of the operation box 4 is closed, a signal is input to the microcomputer 11 via the input circuits 9 and 10, respectively, and the operation result of the microcomputer 11 is output to the output circuit 13 accordingly. Eventually, power is supplied to the motor 16 so that the opening or closing operation is performed on the opening. FIG. 3 is substantially the same. What is important in the present invention is the flowchart of the operation of the embodiment of the present invention shown in FIG. In FIG. 1, a description will be given of a process in which the function and effect described in the claims are derived. First, when the power switch is turned on and started, it is determined whether or not the flag is F = 1. If the flag is not F = 1, the process proceeds to the next when the AT (automatic transmission) is in the P range,
The presence or absence of an open signal is checked. If there is an open signal, it is checked whether or not the next closing SW is out of order. If it is not in the P range on the way, it returns immediately. Also, if F = 1 immediately after the start, is there a closing signal after fixing the P range by shift lock? CHECK
If the answer is YES, the closing control is executed, and if it is already in the closed state, the shift lock release permission & F is set to 0 and the routine returns. If not closed, the routine returns. Is there an open signal mentioned above? When the closing SW is faulty, the opening control is prohibited and a fault is notified. Here, closing SW
In order to determine whether or not there is a failure, a weak current is applied as in a case where a circuit test is generally performed by a tester. And return. That is, OFF is confirmed before opening control is turned ON, and ON is performed only when OFF is normal. This is the most important of the present invention (example). By doing so, it is possible to detect any failure in advance and not to open the opening door (including the roof door), thereby preventing the actual failure state (running impossible, etc.). The present invention is also applicable to a prohibition mechanism for prohibiting traveling when the roof door is opened and a prohibition mechanism for the window glass of each door.

By implementing the present invention, all of the above objects can be achieved. That is, it is possible to prevent a running impossible state due to a closing operation failure of the opening / closing body and a theft due to holding the open state, which may occur in the on-vehicle opening / closing body control device in which various safety measures are taken.
