A keyless system comprising: an on-vehicle receiver for controlling a predetermined state; wherein the on-time detected by the control means is detected by an on-time detecting means while the transmission switch is on, and the first on-time detected by the control means is set to a predetermined first time. It is determined whether it is longer or shorter than a set time, and when the ON time is shorter than the first set time, the remote control signal is transmitted from the transmission circuit under the control of the control means for a fixed first transmission time. When the ON time is longer than the first set time, after the transmission switch is turned off, the transmission switch is turned on again. Times when each ON time is shorter than a second set time set in advance by the control means, each transmission time of 0 second, and each ON time is longer than the second set time. May be multiplied by a predetermined multiple so as to be different for each ON time, to obtain each set transmission time, and to transmit the remote control signal for a second transmission time obtained by adding the set transmission times.

A keyless system comprising an on-vehicle receiver that controls the state of the transmission switch, wherein the on time of the transmission switch is detected by on-time detection means, and the on-time detected by the control means is longer than a predetermined set time. Is determined to be longer or shorter, and when the on-time is shorter than the set time, the remote control signal is transmitted from the transmitting circuit under the control of the control means for a constant first transmission time. When the time is longer than the set time, the second transmission is performed from each set transmission time set in advance corresponding to each ON time. Obtained between, it may transmit the longer second transmission time the remote control signal than the first transmission time.

Further, as in the invention according to claim 6, a portable transmitter for transmitting a remote control signal from a transmission circuit by turning on a transmission switch, and an actuator driven by receiving the remote control signal to control a load.

As described above, a receiving circuit is provided in the portable transmitter, and a transmitting circuit is provided in the on-vehicle receiver, and the load control is performed while the on-vehicle receiver continues to receive the remote control signal. When the load ends and the load returns to the original state, a transmission stop command signal is output from the transmission circuit of the on-vehicle receiver, and the transmission stop command signal is output by the reception circuit of the portable transmitter. The reception of the transmission stop command signal causes the output of the remote control signal from the transmission circuit of the portable transmitter to be stopped, or the portable transmitter transmits the remote control signal as described in claim 9. The transmission of the remote control signal may be stopped when the transmission switch is turned on during the continuation.

[0013]

According to the first aspect of the present invention, the ON time of the transmission switch is detected by the ON time detecting means, and the control means determines whether the detected ON time is longer or shorter than a predetermined set time. When the ON time is shorter than the set time, a remote control signal is transmitted from the transmission circuit under the control of the control means for a first transmission time, and when the ON time is longer than the set time, the control of the control means is performed. Thus, since the transmission circuit transmits a remote control signal for a second transmission time that is a predetermined multiple of the ON time, the output time of the remote control signal can be appropriately changed by selecting the ON time of the transmission switch.

[0014] According to the present invention, the on-time detecting means detects the time during which the transmission switch is on, and controls whether the detected on-time is longer or shorter than a predetermined set time. When the ON time is shorter than the set time, a constant first transmission time remote control signal is transmitted from the transmission circuit under the control of the control means, and when the ON time is longer than the set time, Under the control of the control means, the ON time of the ON time is set to be n times longer than the ON time of the transmission switch from the transmitting circuit.
Even if the remote control signal is transmitted twice the second transmission time, the output time of the remote control signal can be appropriately changed.

Further, when the transmission switch of the portable transmitter outputs a remote control signal for a predetermined time if the transmission switch is turned on once, the transmission switch is continuously operated at an interval within a predetermined time. When the transmission switch is turned on a plurality of times, the remote control signal may be transmitted from the transmission circuit for a time obtained by multiplying the fixed time by the number of times the transmission switch is turned on under the control of the control means.

On the other hand, the on-time detecting means detects the time during which the transmission switch is on, and controls whether the detected on-time is longer or shorter than a predetermined set time. When the on time is shorter than the set time, a constant first transmission time remote control signal is transmitted from the transmission circuit under the control of the control means, and when the on time is longer than the set time, After the transmission switch is turned off, the transmission switch is turned on and off again. When each of the on times is shorter than a second set time set in advance by the control means, each transmission time of 0 second and each of the on times is turned off. When the time is longer than the second set time, each set time is multiplied by a predetermined multiple so as to be different for each ON time, and each set transmission time is obtained. The second transmission time obtained by adding the signal time may transmit the remote control signal.

According to a fifth aspect of the present invention, the ON time of the transmission switch is detected by ON time detecting means, and whether the ON time detected by the control means is longer than a predetermined set time. It is determined whether the ON time is shorter than the set time, and when the ON time is shorter than the set time, the remote control signal is transmitted from the transmitting circuit under the control of the control means for a fixed first transmission time, and the ON time is set to the set time. A longer transmission time, a second transmission time is obtained from each set transmission time set in advance corresponding to each ON time, and a second transmission time longer than the first transmission time. A signal may be transmitted.

On the other hand, when only the transmission switch is turned on, the remote control signal is transmitted from the transmission circuit for a fixed first transmission time under the control of the control means. After providing each input device corresponding to each of the numbers up to and performing a predetermined operation on each of the input devices to set a second transmission time,
The remote control signal may be transmitted.

Also, when the control of the load is completed and the load returns to the original state while the on-vehicle receiver continues to receive the remote control signal, the on-vehicle receiver may be used. By canceling the reception of the remote control signal by the receiver and setting the in-vehicle receiver to a reception standby state after a lapse of a predetermined time from the end of the reception of the remote control signal, for example, when the load is a trunk of an automobile, the trunk is once opened. The trunk is not accidentally opened again after closing.

Further, a receiving circuit is provided in the portable transmitter and a transmitting circuit is provided in the on-vehicle receiver so that the on-vehicle receiver continues to receive the remote control signal. When the load control ends and the load returns to the original state, a transmission stop command signal is output from the transmission circuit of the in-vehicle receiver, and the transmission stop command signal is received by the reception circuit of the portable transmitter. By stopping the output of the remote control signal from the transmitting circuit of the portable transmitter, it is possible to prevent power consumption of the portable transmitter.

On the other hand, when the transmission switch is turned on while the portable transmitter continues to transmit the remote control signal, the transmission of the remote control signal is stopped. It is possible to prevent the trunk from being accidentally released after the trunk is once opened and then closed, and to prevent the power consumption of the portable transmitter from being consumed.

FIG. 1 is a flowchart for explaining the operation of a first embodiment in which the present invention is applied to a portable transmitter of a trunk opener of an automobile, and FIG. 2 is an embodiment in which the present invention is applied to a transmitter of an automobile trunk opener. FIG. 3 is a block diagram of a keyless system to which the present invention is applied.

First, the configuration of the keyless system will be described.

As shown in FIG. 3, when the transmission switch 2 of the portable transmitter 1 is turned on, the on-time detecting means 3 operates and the timer circuit 4 starts counting.
The on-time is detected by the on-time detecting circuit 3 from the count time of the timer circuit 4 when the power is turned off, and whether or not the on-time is longer than a predetermined time set by the transmitting CPU 5 as the control means is determined. If it is determined that the time is short, the transmission circuit 6 is controlled by the CPU 5, and an unlock signal corresponding to a remote control signal for remotely controlling the trunk as a load to the predetermined standby state is transmitted through the antenna 7 for a predetermined time. The signal is transmitted from the circuit 6. In addition, in FIG.
This is a ROM that stores a control program of U5, a vehicle-specific identification code, and the like.

When the unlock signal is received by the receiving circuit 13 via the antenna 12 on the in-vehicle receiver 11, the driving circuit 15 is controlled by the CPU 14 on the receiving side to receive the unlock signal. During this operation, the actuator 16 of the trunk opener is driven by the drive circuit 15, and the trunk is controlled to be openable. In FIG. 3, reference numeral 17 denotes a timer circuit which is controlled by the CPU 14 to count a predetermined time, and 18 denotes a ROM which stores a control program of the CPU 14, an identification code for each vehicle, and the like.

Next, a series of control operations will be described with reference to the flowcharts of FIGS.

First, the operation of the transmitter will be described.

As shown in FIG. 1, it is determined whether or not the transmission switch 2 has been turned on (step S1). If the determination result is NO, this determination is repeated until the determination result becomes YES. If the result is YES, the on-time detecting means 3 operates to start counting by the timer circuit 4 (step S2), and thereafter, it is determined whether or not the transmission switch 2 is turned off (step S3). If the result is NO, this determination is repeated until the determination result becomes YES, and if the determination result is YES, the counting of the timer circuit 4 is stopped (step S4).

Then, it is determined whether or not the time counted by the timer circuit 4, that is, the ON time t of the transmission switch 2 is equal to or longer than a preset time t1 (step S5). If the ON time t is shorter than the set time t1, the first transmission time t2
The time unlock signal is transmitted from the transmission circuit 6 via the antenna 7 (step S6), and if the result of the determination in step S5 is YES, the ON time t, which is longer than the first set time t2, is multiplied by α times. 2 is calculated (step S7), and the calculated t3 time unlock signal is transmitted from the transmitting circuit 6 via the antenna 7 (step S7).
8) Then, the operation ends after the process of step S6 is performed.

At this time, the unlock signal includes an identification code assigned to the vehicle in advance.

Next, the operation of the receiver will be described.

As shown in FIG. 2, it is determined whether or not the unlock signal from the transmitting circuit 6 has been received by the receiving circuit 13 via the antenna 12 (step T1). This determination is repeated until the determination result becomes YES, and if the determination result is YES, it is determined whether or not the identification code included in the received unlock signal matches the identification code assigned to the vehicle. (Step T2). If the determination is NO, the process returns to Step T1, and if the determination is YES, the CPU 1
4 controls the drive circuit 15 and the actuator 16
Is driven, the trunk opener is unlocked, and the trunk is appropriately controlled to be openable (step T3), and the process returns to step T1.

Therefore, for example, when the driver carries luggage from a remote location and loads it in the trunk of the car, the transmission switch 2 of the transmitter 1 is turned on in advance for a time longer than the set time t1, so that the normal time t2 is exceeded. Long t3
Since the unlock signal is output from the transmission circuit 6 for the time period (= t × α), the trunk can be opened while the unlock signal is being output. When the vehicle reaches the area, it is possible to prevent the inconvenience that the output of the unlock signal is already stopped, and the driver always opens the trunk hands-free by selecting the ON time of the transmission switch 2 according to the situation. Can be very convenient.

In the above embodiment, when the ON time of the transmission switch 2 exceeds the predetermined time t6, the time obtained by multiplying the time t6 by α is equal to the time when the ON time exceeds the predetermined time t6 than α. If the time obtained by multiplying by β by a large β is added to obtain the second transmission time, the second transmission time can be reduced in a shorter time than in the above-described embodiment even when it is desired to transmit the unlock signal for a long time. It is convenient because it can be set. A second transmission time t, which is an output time of the unlock signal,
3 may be a time β times the ON time t of the transmission switch 2, and when the ON time t of the transmission switch 2 is longer than the set time t 1, a predetermined time after the transmission switch 2 is turned off, for example, the transmission switch Of course, after the elapse of n times the ON time t of 2, the transmission circuit 6 may output an unlock signal for a time m times the ON time t.

Further, when the transmission switch 2 is continuously turned on p times within an interval of a predetermined time, an unlock signal is output from the transmission circuit 6 for a time p times the number of times the predetermined time is turned on. Even in this case, the same effect as in the above embodiment can be obtained.

Further, even if the second transmission time can be directly set by performing a predetermined operation on a numerical input device such as a numeric keypad or a dial before turning on the transmission switch 2,
The same effect as that of the above embodiment can be obtained, and the second transmission time can be set accurately, which is convenient.

Further, as a third embodiment, the operation of the portable transmitter 1 may be as shown in FIG. 4, and instead of performing the processing of step S5 and subsequent to the processing of step S4 described above, the following is described. Processing may be performed.

That is, after the processing of step S4, it is determined whether or not the switch is turned on for the first time (step S9). If the result of this determination is YES, the timer circuit 4
It is determined whether or not the time counted by the above, that is, the ON time t of the transmission switch 2 is equal to or longer than a preset set time t7 (step S10), and the determination result is NO, that is, the ON time t is longer than the set time t7. Is too short, the first
The unlock signal is transmitted at time t2, which is the transmission time of
Is transmitted via the antenna 7 (step S11),
On the other hand, if the decision result in the step S10 is YES, the processes from the step S1 to the step S4 are performed again,
If the decision result in the step S9 is NO, it is determined whether or not the switch is turned on for the second time (step S12). After the transmission time t8 is obtained (step S13), steps S1 to S1 are performed again.
4 are performed, and the determination result of step S12 is N
If O, each transmission time t9 which is y times the third ON time t
Is obtained (step S14), and the second transmission time t10 is calculated by adding the transmission times t8 and t9 (step S14).
15) The calculated unlock signal at time t10 is transmitted from the transmission circuit 6 via the antenna (step S1).
6) If the operation ends after the process of step S11, an appropriate numerical value is set for x and y, so that even when the unlock signal is transmitted for a long time, the second You can set the transmission time. Also,
Needless to say, the same effects as in the above embodiment can be obtained.

FIG. 5 shows a case where the third embodiment is used for an actual portable transmitter. As shown in FIG. 5A, the portable transmitter is provided with a transmission switch 2 and a light emitting diode 23. The time when the first transmission switch 2 is turned on is, for example, less than 2 seconds (FIG. 4, t7 = 2 in step S10).
When the transmission switch 2 is turned on for 2 seconds or more, the transmission signal is transmitted once (step S11). As shown in FIG. 5B, the light emitting diode 23 blinks green at short time intervals. When the second transmission switch 2 is turned on (step S12), the second ON time is multiplied by 100 (x = 10 in step S13).
0) Set the hundreds digit of the second transmission time. At this time, as shown in FIG. 5C, the light emitting diode 23 flashes green every second so that the lapse of the ON time can be visually confirmed. After the second transmission switch 2 is turned off, the light emitting diode 23 flashes in red at short time intervals as shown in FIG. 5B, and when the third transmission switch 2 is turned on, the third on-time is ten times longer. Then (y = 100 in step S14), the tens place of the second transmission time is set. At this time, FIG.
As shown in (c), the light emitting diode 23 flashes every second so that the elapsed time of the on-time can be visually confirmed.
After the third transmission switch 2 is turned off, the second transmission time unlock signal obtained by setting as described above is transmitted. If the unlock signal is transmitted at regular intervals during this transmission, the power consumption of the portable transmitter can be prevented from being consumed, and furthermore, if the light emitting diode 23 is turned on and off in synchronization with the transmission time of the unlock signal, the transmission is performed. It is convenient to check. In the above-described embodiment, the order of 10 seconds may be set by the second ON time, and the minute may be set by the third ON time, or the setting by the second ON time and the third ON time. May be reversed. Further, instead of turning on the transmission switch 2 a plurality of times, a plurality of switches may be provided, and each position may be set by each switch.

Further, as a fourth embodiment, a portable transmitter 1
May perform the processing shown in FIG.

In FIG. 7, the operation from step S1 to step S4 is the same as the corresponding step in FIG. Then, it is determined whether or not the time counted by the timer circuit after the processing in step S4, that is, the ON time t of the transmission switch 2 is equal to or longer than a preset time t7 (step S10). If the on-time t is shorter than the set time t7, an unlock signal is transmitted from the transmission circuit 6 via the antenna 7 from the transmission circuit 6 for the first transmission time t2 (step S11). If YES, the second transmission time is obtained from the preset transmission time for the ON time t (step S17), and the second transmission time unlock signal longer than the first set time t2 is output. The signal is transmitted from the transmission circuit 6 via the antenna (step S18), and thereafter, the operation ends after the process of step S6.

A practical portable transmitter according to the fourth embodiment (FIG. 6)
The following shows the case of using Each set transmission time set in advance with respect to the above-mentioned ON time is the ON time set time t
It is set to increase by 10 seconds every 0.5 seconds after the elapse of 7 seconds, and 10 seconds when 0.5 seconds elapses after the elapse of 7 seconds. Therefore, 1 minute is set when 3 seconds elapse, When 3 seconds or more have elapsed, the setting is made to increase by 1 minute every 0.5 seconds, that is, 5 minutes is set when 5 seconds have elapsed. The portable transmitter shown in FIG. 6 is provided with ten transmission switches 2 and a plurality of light emitting diodes 24 corresponding to each set transmission time arranged in a line in an upper and lower order in ascending order of the set transmission time. , Each light emitting diode 24 emits light corresponding to each set transmission time determined with the elapse of the on-time. The operation of the portable transmitter will be described. When the transmission switch 2 is turned on and the ON time is shorter than a preset time t7, an unlock signal is transmitted once after the transmission switch 2 is turned off (step S11). When the ON time is longer than the set time t7, the transmission time setting mode is set. Each time the ON time exceeds the set time t7 and 0.5 seconds elapse, the light emitting diodes 24 are sequentially illuminated from the bottom and set. The transmission time can be confirmed (step S17). Thereafter, when the transmission switch 2 is turned off, a set transmission time unlock signal determined with respect to the ON time is transmitted (step S1).
8). The setting of the set transmission time is not limited to the above example.

Further, the second transmission time may be indicated by a liquid crystal, a light emitting diode or a lighting tube.

Further, as a fifth embodiment, the operation of the on-vehicle receiver 11 may be as shown in FIG. 8, and the following processing may be performed following the processing of step T3.

That is, after the processing in step T3, it is determined whether or not the reception of the unlock signal has been completed (step T3).
4) If this determination result is NO, this determination is repeated until the determination result becomes YES, and if the determination result is YES, the CPU 14 controls the timer circuit 17 to start counting for a predetermined time (step T5). ), Timer circuit 1
It is determined whether or not an unlock signal has been received from the transmission circuit 6 during the counting of step 7 (step T6). If the result of the determination is YES, the process returns to step T4. It is determined whether the count time of the timer circuit 17, that is, the time interval t4 from the previous unlock signal to the reception of the next unlock signal is equal to or longer than a predetermined time t5 (step T7), and if the determination result is NO. If the determination result is YES, the process returns to step T6.
It may return to 1.

Therefore, when the trunk, which is a load, is opened and closed while the on-vehicle receiver 11 continues to receive the unlock signal, the unlock signal by the receiving circuit 13 of the on-vehicle receiver 11 is obtained. May be canceled, and the reception circuit 13 may be set to a reception standby state after a lapse of a predetermined time from the end of the reception of the unlock signal. For example, the trunk may be opened once, closed, and then opened again by mistake. Can be prevented.

The portable transmitter 1 is provided with a receiving circuit, the vehicle-mounted receiver 11 is provided with a transmitting circuit, and the trunk, which is a load, while the vehicle-mounted receiver 11 continues to receive the unlock signal. When the is opened and closed, a transmission stop command signal is output from the transmission circuit provided in the on-vehicle receiver 11, and the reception circuit provided in the portable transmitter 1 receives the transmission stop command signal to transmit the portable transmission signal. The output of the unlock signal from the transmission circuit 6 of the transmitter 1 may be stopped, thereby making it possible to prevent power consumption of the portable transmitter 1 from being consumed.

When a switch such as the transmission switch 2 is operated while the portable transmitter is transmitting the unlock signal, the output of the unlock signal may be stopped.
The power consumption of the portable transmitter can be prevented, the trunk can be prevented from being accidentally opened after the trunk has been opened and then closed, and the unlock signal can be released even when it is no longer necessary to open the trunk. The operation that the trunk is opened while the transmission is continued can be avoided.

Further, when transmitting the unlock signal for the second transmission time, if the unlock signal is transmitted at predetermined time intervals, the power consumption of the portable transmitter 1 is prevented from being consumed. be able to.

By the way, as shown by the broken line in FIG. 3, a light emitting diode 20 is provided in the portable transmitter 1, and while the transmission switch 2 is turned on, the light emission is performed by the CPU 5 at regular intervals such as one second. The diode 20 may be made to blink so that the user can visually confirm the on-time. Alternatively, as shown by a broken line in FIG. 3, the portable transmitter 1 is provided with a buzzer 21 and the transmission switch 2 is turned on. Then, while the transmission circuit 6 is outputting the unlock signal, the CPU 5 outputs the buzzer 2 at regular intervals such as one second, for example.
1 may be sounded so that the user can confirm the on-time by ear. Further, the second transmission time set by the numerical display device using a light emitting diode or a liquid crystal or the like may be used to confirm the user. May be displayed.

In the above embodiment, the present invention is applied to a trunk opener. However, a so-called keyless entry system for unlocking a door of an automobile by remote control, or a remote control for closing and opening a garage door. It is needless to say that the present invention can be applied to other keyless systems such as a system performed by the method described above, and the same effect as that of the above embodiment can be obtained.

Further, the above means are not limited to those shown in FIG.

[0053]

As described above, according to the first aspect of the present invention, when the transmission switch is shorter than a predetermined set time, the transmission circuit of the portable transmitter transmits a fixed first transmission time. When the control signal is transmitted and the on-time is longer than the set time, the remote control signal is transmitted from the transmission circuit for a second transmission time which is twice as long as the on-time. Sometimes, the inconvenience that the output of the remote control signal is already stopped can be prevented, and the output time of the remote control signal can be appropriately changed by selecting the ON time of the transmission switch, so that the output of the remote control signal can be changed. It is possible to always control the load.

Further, as in the second aspect of the present invention, the time during which the transmission switch is turned on is detected by the on-time detecting means, and whether the detected on-time is longer or shorter than a predetermined set time is controlled. When the ON time is shorter than the set time, a constant first transmission time remote control signal is transmitted from the transmission circuit under the control of the control means, and when the ON time is longer than the set time, Under the control of the control means, the ON time of the ON time is set to be n times longer than the ON time of the transmission switch from the transmitting circuit.
Even if the remote control signal is transmitted twice as long as the second transmission time, the output time of the remote control signal can be appropriately varied, and the same effect as the invention of claim 1 can be obtained. The effect that the consumption of the battery in the transmitter can be suppressed can also be obtained.

Further, when the transmission switch of the portable transmitter is turned on once to output a remote control signal for a certain period of time as in the invention according to the third aspect, the transmission switch is continuously operated at intervals within a predetermined time. When the remote control signal is transmitted from the transmitting circuit for a time obtained by multiplying the fixed time by the number of times the transmission switch is turned on by the control of the control means when the remote control signal is turned on a plurality of times by the control means, the same effect as the invention of claim 1 can still be obtained. Obtainable.

Further, as in the invention according to claim 4, the time during which the transmission switch is turned on is detected by the on-time detecting means, and whether the detected on-time is longer or shorter than a predetermined set time is controlled. When the ON time is shorter than the set time, a constant first transmission time remote control signal is transmitted from the transmission circuit under the control of the control means, and when the ON time is longer than the set time, After the transmission switch is turned off, the transmission switch is turned on and off again, and when each of the on-times is longer than a second set time set in advance by the control means, it is set in advance so as to be different for each on-time. Each set transmission time is multiplied by a predetermined multiple to obtain each set transmission time, and a second transmission time remote control signal obtained by adding the set transmission times is transmitted. Motomeko 1 and can obtain the same effect, also can be set in a short time even if you want to set a longer second transmission time.

According to a fifth aspect of the present invention, the time during which the transmission switch is turned on is detected by the on-time detecting means, and whether the on-time detected by the control means is longer or shorter than a predetermined set time is determined. Judging, when the on-time is shorter than the set time, the remote control signal is transmitted from the transmitting circuit under the control of the control means for a fixed first transmission time, and the on-time is longer than the set time. Sometimes, a second transmission time is obtained from each set transmission time set in advance corresponding to each ON time, and the remote control signal is transmitted for a second transmission time longer than the first transmission time.

And the second transmission time can be set more accurately.

On the other hand, when the load control is completed and the load returns to the original state while the on-vehicle receiver continues to receive the remote control signal, the on-vehicle receiver is turned on. By canceling the reception of the remote control signal by the receiver and putting the in-vehicle receiver in a reception standby state after a lapse of a predetermined time from the end of the reception of the remote control signal, for example, when the load is a trunk of an automobile, the trunk is opened once It is possible to prevent the trunk from being accidentally opened again after closing.

According to the present invention, the receiving circuit is provided in the portable transmitter and the transmitting circuit is provided in the on-vehicle receiver so that the on-vehicle receiver continues to receive the remote control signal. When the load control ends and the load returns to the original state, a transmission stop command signal is output from the transmission circuit of the in-vehicle receiver, and the transmission stop command signal is received by the reception circuit of the portable transmitter. By stopping the output of the remote control signal from the transmitting circuit of the portable transmitter, it is possible to prevent power consumption of the portable transmitter.

Further, when the transmission switch is turned on while the portable transmitter continues to transmit the remote control signal, the transmission of the remote control signal is stopped. It is possible to prevent the trunk from being accidentally released after the trunk is once opened and then closed, and to prevent the power consumption of the portable transmitter from being consumed.
