Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for wirelessly operating vehicle doors, trunks, lights and the like.

[0002]

2. Description of the Related Art In a conventional wireless unlocking system, for example, as disclosed in Japanese Utility Model Laid-Open No. 5-78845, the ignition key of the vehicle on the transmitter side is provided with a switch for opening the door and a switch dedicated for opening the door. A code corresponding to the function is transmitted by operating any one of the switches, and the code is received by a receiver provided in the vehicle to perform the corresponding operation, for example, opening or closing the door. After that, as the user's needs increase, the switch provided on the ignition key 7 as shown in FIG. 7- (A) includes the conventional door lock switch 111 and door lock switch 112, as well as the trunk lock switch 113, Lighting switch 114
Etc. have come to be installed. Further, in the conventional wireless unlocking system, when the door unlock command is received, the door is unlocked unconditionally.

[0003]

As described above, in addition to the door locking switch 111 and the door unlocking switch 112, the trunk unlocking switch 113 and the illumination switch 114 are provided.
And so on, a switch dedicated to each function is provided, and the transmitter becomes large. Therefore, expensive small parts are required to be integrated with an ignition key, a key holder, or the like of a vehicle. Moreover, since the shape of the switch cannot be made large, it is easy to make a mistake in operating the switch. Also, when a door unlock command is received as in the conventional wireless unlocking system, if the door is unconditionally unlocked, the unlocked state of the vehicle door or trunk can be visually recognized from outside the vehicle by another person. Therefore, when the door is unlocked from a remote place or when the unlock command is erroneously output, there is a problem that the possibility of theft or the like increases.

[0004]

DISCLOSURE OF THE INVENTION The present invention is to solve the above-mentioned problems, for which the transmitting means is supposed to transmit only one kind of unique signal, and when the unique signal is received, Depending on the door unlocking state, it outputs a drive control signal that causes the unlocking mechanism driving means to be in the opposite state, then outputs a drive control signal that unlocks the trunk, and then shifts to lighting control. And a drive control means for sequentially outputting a drive control signal. Also, at that time,
An unlocking operation detecting means for detecting that the unlocking member has been unlocked is provided, and when unlocking, a drive control signal for unlocking is output only when an unlocking operation signal is detected.

[0005]

By doing so, it becomes possible to perform a plurality of controls such as locking and unlocking by operating a single switch, which makes it possible to downsize the transmitter structure and reduce the manufacturing cost. You can do it, and you can avoid erroneous operations. Also, when unlocking, the drive control signal for unlocking is output only when an unlocking operation signal for operating the outer handle of the door is detected, so even if the unlocking signal is sent, The upper part is always in the locked state, and it is not known to others that it is in the unlocked state when the outer handle of the door is operated, so security such as theft prevention is improved.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows a schematic configuration of a first embodiment of the present invention. A transmitter 1, a receiver 2, a drive controller 3,
The lock / unlock mechanism drive means 4 and the lock / unlock state confirmation device 5 are included.
The transmitter 1 transmits one type of code signal corresponding to each vehicle, and as shown in FIG. 2, the transmission switch 11, the oscillation control unit 12, the oscillation / modulation circuit 13, the amplifier 14, and the antenna 15 are provided. Consists of. Transmission control unit 12
Holds a code unique to each vehicle inside. When the receiver 2 receives a wireless signal with an antenna installed at an appropriate location on the vehicle body, the receiver 2 detects (demodulates) the received signal and sends the obtained code signal to the drive control unit 3.

The drive control section 3 determines whether or not the code signal from the receiver 2 matches the vehicle-specific code signal held in advance. When the code signals match, the lock / unlock status checker 5
A drive control signal is output to the drive mechanism 4 in response to the door lock / unlock state signal from. That is, when the door is in the unlocked state, a control signal for locking the door is output to the drive mechanism 4, and a control signal for locking the door in the locked state is output to the drive mechanism 4. The drive control unit 3 is composed of a microprocessor CPU that operates according to a program as shown in FIG. 5, and the program is stored in a memory. This microprocessor CPU is powered by the car battery
Ignition (IG) on / off status, drivers doors and other three doors open / closed, key insertion / removal signals, door outer handle operation, trunk Signals indicating the locked and unlocked states of the release and driver's doors are respectively given through the input interface (input I / F). Also,
The one type of code signal corresponding to the vehicle, which is received by the receiving antenna, is also detected and waveform-shaped and is input to the microprocessor CPU.

In the embodiment shown in FIG. 5, the drive mechanism 4 rotates the door electric motor Md and the trunk electric motor Mt forward or reverse to open or lock the door (however, in this embodiment, the door electric motor Md is used). The locking is not performed by the electric motor Mt but exclusively by the manual.). As another conceivable embodiment, it is possible to turn on / off the illumination device at a desired location in the vehicle. As shown in FIG. 6, the unlocking / locking state confirmation device 5 is attached in the vicinity of the unlocking / locking portion of the door and detects whether the door is in the open state or in the closed state. It is composed of a changeover switch 5 that switches between an unlock side and a lock side in response. This status signal is given to the microprocessor CPU3, which is a drive control unit, via the input I / F. Specifically, the transmission switch 11 is constituted by only one switch on the ignition key 7 according to the present invention as shown in FIG. 7- (B). Therefore, when this switch is turned on, the code signal is sent to the oscillation / modulation circuit 13, the carrier wave is modulated with the code signal specific to the vehicle, and is transmitted from the antenna 15 via the amplifier 14.
On the other hand, the carrier signal received by the antenna 2 is detected (demodulated), converted into a code signal, and then the drive control unit (CP).
U) 3, and the drive control unit 3 determines whether the code signal received from the receiver 2 matches the vehicle-specific code signal previously stored in the memory. When the code signals match, a drive control signal for reversing the lock / unlock state confirmation signal from the lock / unlock state confirmation device 5 (that is, a signal indicating whether the driver's door is locked or unlocked) is sent. Output to the drive mechanism 4. That is, when the door is in the unlocked state, the door motor Md is rotated in the locking direction to lock the unlocking member, and conversely, when the door is in the locked state, the door motor Md is unlocked. It is rotated to unlock the unlocking member. In addition, in FIG. 7- (B), one switch is connected to the ignition key 7
Although it is configured above, it is not limited to this.
As shown in (C), the transmission switch 1 is placed on the key holder 71.
1 may be configured.

When a plurality of controls are performed by operating a single switch, the control operation of the next control target is started. For example,
When the trunk is in the closed state, the operation of unlocking the trunk or controlling the turning on / off of the interior lighting device is performed.
The unlocking operation of the trunk may be performed by rotating the trunk motor Mt in the unlocking direction as in the case of the door drive control, depending on the presence or absence of the trunk release signal. Further, when the control operation of turning on / off the in-vehicle lighting device is performed, it may be performed by detecting whether it is on or off by a sensor or the like and performing control to reverse the state. Such control itself is often performed, and a description thereof will be omitted. As described above, according to the present invention, since only one switch is required,
It can be easily incorporated into the ignition key or the key holder, and the size can be reduced.

FIG. 3 shows a schematic configuration of the second embodiment of the present invention. The difference from the first embodiment is that an opening operation detector 6 is added to the configuration of the first embodiment. Also here, as in the first embodiment, not only the door of the vehicle but also the trunk is targeted for unlocking. The opening operation detector 6 is composed of a switch 61 attached near the outer handle 8 of the door and a pressure switch 62 attached near the locking mechanism of the trunk 9 as shown in FIG.
In the block diagram of FIG. 5, the switches described as the door handle 61 and the trunk release 62 correspond to this, and open when the outer handle 8 of the door is operated and when the trunk 9 is lifted to the open side. Input operation signal I
Microprocessor CPU which is a drive control unit via
Output to 3. The drive control unit 3 is similar to the first embodiment.
The drive mechanism is controlled according to the received code signal and the unlocking / locking state signal, but the control signal for unlocking is output only when the opening operation signal from the opening operation detector 6 is detected.

Next, the operation flow of the second embodiment will be described with reference to FIG. First, when a signal from the transmitter 1 is received in S1 (meaning step 1, the same applies hereinafter),
In S2, it is determined whether the received code and the code unique to the vehicle match, and if the codes match, the locked / unlocked state of the door and trunk is confirmed in S3. Then, the state of the door is determined (S
4) If the door is in the unlocked state, in S11, a control signal for locking the door is output to the drive mechanism 4. When the door is locked, the timer is set in S5 and the operation of the outer handle is detected (S6). Then, when the outer handle is operated, a control signal for unlocking the door is output to the drive mechanism 4 in S7. Further, the trunk opening operation is detected in S8, and when the trunk opening operation is performed, a control signal for unlocking the trunk is output to the drive mechanism 4 (S9). S6
And S8 are detected until the timer is up (S1
0).

In the above embodiment, the unlocking / locking state confirmation means 5 is used.
6 has been described as a sensor that is attached near the door opening / closing portion as shown in FIG. 6 and confirms whether the door is in the open state or the closed state, but of course the invention is not limited to this. For example, if the memory of the aforementioned microcomputer is used to store the previous unlocked state, the sensor can be omitted, which is advantageous in terms of cost.

[0013]

As described above, according to the first to eighth aspects of the invention, since a plurality of control signals are output by operating a single switch, the structure of the transmitter is miniaturized. In addition, the manufacturing cost is reduced. In addition, erroneous operation is avoided. According to the inventions of claims 5 to 8,
An unlocking operation detecting means for detecting that the unlocking member is operated to be opened is provided, and when the unlocking operation is performed, the drive control signal for unlocking is output only when the unlocking operation signal is detected. Even when the unlocking signal is transmitted, the appearance is always in the locked state, and the security is improved. Further, even when a signal is erroneously transmitted, the unlocking member is always in the locked state unless the unlocking member is operated to open within a certain period of time, so that the unlocked state is not erroneously obtained.
