Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention remotely controls the opening and closing of doors, trunks, etc. in a vehicle by emitting a transmission signal from a portable transmitter; 1: 1. This invention relates to a remote control device for an on-vehicle opening/closing mechanism that is activated.

[Conventional technology]

As shown in Japanese Patent Application Laid-Open No. 59-203178, a conventional device of this type uses a portable transmitter to emit a magnetic pulse unlock signal, which is received by a receiver installed in the vehicle to unlock the door. A device that operates a locking mechanism is known.

[Problem that the invention seeks to solve]

When a device such as the one described above is used to remotely control the opening/closing operation of a trunk, for example, in addition to a door, the unlocking signal is a magnetic pulse, so the device will not operate unless the user gets close to the trunk. Therefore, once the user unlocks the trunk, he or she must move to the vicinity of the door he or she wishes to open, which is a problem. On the other hand, if a radio wave with a wide range of application is used as an unlocking signal instead of a magnetic pulse, the trunk may also be unlocked when the door is unlocked, so a switch is required to switch between the door and the trunk. , the operation becomes complicated and there is a problem of malfunction due to erroneous switch operation. Further, it is preferable that such a portable transmitter be as small as possible, and from this point of view as well, it is preferable that the switches have a structure as simple as possible.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to enable a plurality of opening/closing mechanisms installed at different locations on a vehicle to be remotely operated without malfunctioning due to unintentional operation. do.

〔Example〕

The present invention will be explained in detail below based on embodiments shown in the drawings.

FIG. 1 shows a block diagram of an embodiment in which the present invention is applied to a wireless door opening/closing control system for a vehicle. This system consists of a small transmitter that can be carried by the driver, and a receiver that is mounted on the car. It consists of a solenoid 3 for locking and unlocking the driver's door, and a solenoid 4 for opening the trunk oven. The transmitter 1 includes a command switch 5 operated by the user, a code generation circuit 6° oscillation circuit 7 that generates an identification code by operating this switch, and a pulse (M number) from the oscillation circuit 7. a first modulation circuit 8 that modulates based on the identification code of the first modulation circuit 8; an amplification circuit 9 that amplifies the output of the first modulation circuit 8;
Then, the transmission signal amplified by the amplification circuit 9 is radiated toward the outside space (3 antennas 10"4iii are installed. Also, the transmitter 1 is equipped with an identification code generated by the code generator 6. A second modulation circuit 111, a light emitting circuit 121, and a light emitting element 13 such as a light emitting diode are provided for converting into an optical signal and emitting the signal to the outside space.

Next, the configuration of the receiver 2 will be explained. Receiver 2 is
It includes a receiving circuit 15 that receives a signal incident on the receiving antenna 14, and the received signal received here is sent to the demodulating circuit 1.
6, the signal is converted into a digital signal and input to the micro combinator 17 manually.

It also includes a light receiving circuit 19 that receives a signal received by a light receiving element 18 such as a photodiode, and the received signal received here is converted into a digital signal by a demodulation circuit 20 and input to the microcomputer 17. . Based on a program to be described later, the microcomputer 17 determines whether the received signal is a signal from the transmitter 1, and also determines whether there is a signal input from the demodulation circuit 20, and activates the solenoid 3 or the solenoid 4. configured to drive.

Here, as shown in FIG. 2, the receiving antenna 14 is disposed at the rear window of the vehicle (2), and the light receiving element 18 is disposed at the rear of the vehicle V. The sensitivity of the receiving antenna 14 is within a circle A centered on the vehicle V in FIG. 2, and the light receiving area of the light receiving element 18 is within a sector B indicated by a dotted line in FIG.

Next, the operation of this embodiment having the above configuration will be explained. FIG. 3 shows a flowchart of the control program for the microcomviator 17.
executes the control program of steps 100-180. When the program starts running, step 11
0 and determines whether there is an optical reception signal. Here, the light emitting element 13 of the transmitter 1 is within the region B of FIG.
When the command switch is turned on, the light from the light receiving element 13 is received by the light receiving element 18, and it is determined that there is a received signal. If there is a received signal, the process proceeds to step 120, the code of the optical signal is read, and the process proceeds to step 130. Step 1
At 30, an identification code indicating that the signal is transmitted from the transmitter 1 is determined, and if so, the trunk oven solenoid 4 is driven at step 140, and if not, the process returns to step 110.

In step 110, if there is no received signal, the process proceeds to step 115, where it is determined whether there is a received radio signal. Here, if the transmitter 1 is within the area A shown in FIG. 2 and the command switch is turned on, it is determined that the radio wave has been received.

If there is a received signal, the process proceeds to step 150, the code of the radio wave signal is read, and the process proceeds to step 160.

In step 16Q, it is determined whether or not the signal is transmitted from the transmitter 1. If so, the solenoid 3 that reverses locking and unlocking of the door is driven, and if not, the process returns to step 110.

In the above operation, when the transmitter 1 is within area B,
By turning on the command switch, you can control both the opening and closing of the driver's door and the opening of the trunk, but even if you are in area A, if you are outside area B, the opening and closing of the driver's door will be controlled. I can open the trunk, but I can't open the trunk. Therefore, it is possible to prevent the trunk from being opened by mistake.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be implemented in various ways. For example, in the above-mentioned embodiments, the opening and closing of the trunk is controlled by optical signals, but it may also be controlled by using magnetic pulses. good. In this case, the sensitivity of the magnetic pulse is defined as the area within circle C in FIG. In addition to magnetic pulses, ultrasonic waves may also be used.

〔Effect of the invention〕

As described above, according to the present invention, the first opening/closing mechanism can be remotely controlled from a place where the first demodulating means is provided, and the second opening/closing mechanism can be controlled remotely from the location where the second demodulating means is provided. Since it is not possible to remotely control I, z, and ti from near the location, when the first opening/closing mechanism is remotely controlled, it is possible to prevent the second opening/closing mechanism from being erroneously controlled.

Furthermore, by operating one command switch, the opening and closing operations of the two opening and closing mechanisms can be controlled and shifted by τ■, contributing to simplification of operation and miniaturization of the mobile transmitter 22.
