Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] <Industrial Field of Application> The present invention relates to a remote control device for a vehicle, and particularly to a remote control device for a vehicle that selectively operates a plurality of in-vehicle devices.

<Prior Art> Various remote control devices for automobiles have been proposed for locking and unlocking automobile doors, for example. An example of such a remote control device is to face a fully unlocked door and press a push button switch on a portable transmitter to transmit an infrared signal to a receiver on the vehicle body.
There is a device that unlocks a door locking device (1M lock) based on the above signal using a control device connected to a receiver.

However, for example, if you want to selectively open only the trunk of this car or selectively unlock only the driver's side door, this may unnecessarily affect the locking device of other doors, and the power supply Not only does it consume the transmitter, but each time the transmitter is operated, it is necessary to check whether other doors, etc. are locked or unlocked, which tends to make the work complicated. Therefore, it is conceivable to provide multiple switches in the transmitter and transmit multiple types of code signals to the receiver side in response to each switch, but this not only tends to increase the size of the transmitter, but also causes problems inside the transmitter. There is a problem that the mechanical structure and electrical structure of the device become complicated.

<Problems to be Solved by the Invention> In view of the problems of the prior art, the main object of the present invention is to provide a transmitter that does not become large or complicated, is easy to operate, and can be installed in multiple vehicles. An object of the present invention is to provide a remote control device for a vehicle that can selectively operate devices.

[Structure of the Invention] <Means for Solving the Problems> According to the present invention, such an object is to provide a transmitter that transmits a signal by operating a switch, a receiver on the vehicle body that receives the signal, and a receiver that receives the signal. a control device that operates on-vehicle equipment based on the signal, and a plurality of control devices according to at least one of the length of time the switch is kept on and the number of times the switch is turned on and off within a predetermined time. This is achieved by providing a remote control device for a vehicle that is characterized by selectively operating on-vehicle equipment.

In this way, by turning the switch installed on the transmitter side on and off multiple times within a predetermined period of time, or keeping it on for a long time, you can selectively select the corresponding device from among multiple in-vehicle devices. can be operated.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 schematically shows the configuration of a remote control device for an automobile based on the present invention. A key device 2 having a mechanical key portion 2a for driving an automobile 1 has a transmitter 4 built into its grip portion 3. Further, a switch 5 is provided on the surface of the grip part 3, and by pressing the switch with a finger, an infrared code signal is transmitted from a light emitting element 6, which may be an LED element, to the ceiling of the vehicle interior of the automobile 1. The signal is transmitted toward a light receiving element 7, which may be a photodiode provided. The light receiving element 7 is connected to a control device 9 having a built-in receiver.

This control device 9 includes an actuator 11 connected to an on-vehicle battery (not shown) and connected to lock or unlock a door lock 10 on the driver's side door, and an actuator connected to a door lock 12 on the passenger's side door. 1
3 and an actuator 15 connected to the trunk lock 14 to selectively drive the trunk lock 14.

FIG. 2 is a block diagram showing the internal configuration of the transmitter 4 and the control device 9. As shown in FIG. The transmitter 4 has a circuit 16 connected to the push button switch 5, and the trigger circuit 16 operates at a predetermined level from the time when the first trigger is confirmed in the circuit, that is, from the time when the push button switch 5 is turned on. A timer 17 that measures time T, a counting circuit 18 that adds up the number of times the push button switch 5 is turned on until the timer 17 times up, and a determination circuit that determines whether the push button switch 5 is turned on or not. 19. Further, the output end of the counting circuit 18 is connected to a transmission mode discrimination circuit 20. The output end of the transmission mode discrimination circuit 20 is connected to the first to third code generation circuits 21 to 23. Further, the output end of the push button switch ON state determination circuit 19 is connected to a third code generation circuit 23. These code generation circuits 21~
The output terminal of 23 is connected to an output circuit 24 that controls the light emitting element 6 .

On the other hand, the light receiving element 7 on the vehicle 1 side that receives the infrared signal transmitted from the light emitting element 5 described above is connected to a receiving circuit 26 that functions as a receiver in the control device 9. The output end of this receiving circuit 26 is connected to a code signal matching circuit 27. Further, this code signal verification circuit 27 is connected to a code storage circuit 28. The output end of the code signal verification circuit 27 is connected to an operating device determination circuit 29 for determining which of the driver's side door lock 10, passenger's side door lock 12, and trunk lock 14 is to be activated. The output terminal is connected to an operation mode discrimination circuit 30 that discriminates whether to lock or unlock. The operating mode determination circuit 30 is connected to each actuator 11, 12, 14 via output circuits 31-33.

Fig. 3 is a flowchart showing the procedure for actually operating each actuator 11, 12, 14 after turning on the push button switch 5, and Fig. 4 is a time chart for the process. The operation procedure of this embodiment will be explained.

First, when the push button switch 5 is turned on at step 35 in FIG. 3, the process proceeds to step 36 and the timer 17 is started. Next, in steps 37 and 38, the number of times the push button switch 6 is turned on and off within a predetermined time T is counted (P/C) by the counting circuit 18. When it is determined in step 38 that the predetermined time T has elapsed, the process proceeds to step 39, and the number of times the push button switch 5 has been turned on and off (
It is determined whether or not P/C) is once, and if it is once, the process proceeds to step 40. Then, in this step, timer 1
The switch-on state determination circuit 19 determines whether or not the operator continues to turn on the push button switch 5 even after a predetermined time T has elapsed since the start of 7. If the push button switch 5 has not continued to be turned on, the process proceeds to step 41 and the driver's seat is switched on. The actuator 11 of the side door bolter 10 is operated. This is shown at part A in the time chart of FIG. That is, in push button switch 5,
If an on/off operation for a time t1 shorter than this time T is performed only once during a predetermined time T after the switch is first turned on, the first code signal C1 is controlled 1vl after the predetermined time elapses. Send to the position 9 side, actuator] 1
Activate.

On the other hand, if the operator continues to turn on the push button switch 5 in step 40, the process proceeds to step 42 and the actuator 15 is activated. This is shown in part C of the time chart in FIG. That is, if the push button switch 5 is continuously turned on for 12 hours longer than the predetermined time T, the third code signal QC3 is sent to the control device 9 side when the predetermined time T has elapsed, and the actuator 15 is actuated.

On the other hand, if it is determined in step 39 that the number of times the push button switch 5 has been turned on within the predetermined time T is not 1, the process proceeds to step 43, where it is determined whether or not the number of times is 2.
If it is, the process advances to step 44 and the actuator 13 is activated. This is shown in part 8 of the time chart in FIG. That is, if the push button switch 5 is turned on twice for 11 hours within a predetermined time period T after the switch is turned on for the first time, the second code signal is generated after the predetermined time period T elapses. C2 is sent to the control device 9 side, and the actuator 13 is activated. If the push button switch 5 is turned on and off three times or more in steps 37 and 38, the process returns to step 35 without operating each actuator in step 43.

It goes without saying that the present invention is not limited to the above-mentioned embodiment and can be applied in various ways. For example, in this embodiment, three types of code signals are prepared on the transmitter side. The on/off operation timing of the button switch may be directly transmitted to the receiver on the vehicle body, and the receiver may determine the timing and operate each vehicle-mounted device via the control device. Also,
In this embodiment, the driver's side door lock, passenger's side door lock, and trunk lock are locked or unlocked, but the push button switch may be turned on and off three or four times or more within a predetermined time. It is also possible to selectively operate a large number of in-vehicle devices, such as the rear seat side door lock and engine starter, by turning on and off briefly and then turning on for a long time.

[Effects of the Invention] As described above, according to the present invention, it is possible to selectively remotely control multiple in-vehicle devices without complicating operations, increasing the size of the transmitter, or complicating the mechanical and electrical aspects. The effect is extremely large because it makes it possible to do this and improves ease of handling.
