As shown in FIG. 1, an electronic key system 10 </ b> A according to the first embodiment includes a portable transceiver 12 carried by a user (user) and a control device 14 mounted on a real vehicle 100 (see FIG. 4). And The portable transceiver 12 may have a key shape and an IC chip incorporated therein, or a card-shaped external device and an IC chip incorporated therein. When applied as a keyless system, the shape of a card is used. In the present embodiment, a description will be given assuming a portable transceiver 12 having a card shape. Further, since the portable transceiver 12 is generally called an electronic key, the portable transceiver is also referred to as an electronic key 12 in the following description.
[0022]
The electronic key 12 has the shape of a card as described above, and includes a battery 20, a power supply circuit 22, a CPU 24, a reception circuit 26, and a transmission circuit 28 as shown in FIG.
[0023]
The power supply circuit 22 is a circuit that supplies power from the battery 20 to the reception circuit 26, the transmission circuit 28, and the CPU 24. The receiving circuit 26 has a receiving antenna (not shown), receives the request signal Sr and the like transmitted from the control device 14 through the receiving antenna, extracts the request signal Sr from the carrier wave, and demodulates the signal. The demodulated signal is supplied to the CPU 24. The carrier frequency of the request signal Sr is 100 kHz to 300 kHz.
[0024]
The CPU 24 executes at least two programs (a request signal comparison unit 30 and a response signal generation unit 32). The request signal matching means 30 checks whether the signal supplied from the receiving circuit 26 is the request signal Sr, and if the signal is the request signal Sr, transfers control to the response signal generating means 32. The response signal generating means 32 reads out ID data recorded in a ROM (not shown) based on the request from the request signal collating means 30, adds an attribute indicating a response to the ID data, and generates the transmission data Dt as transmission data Dt. 28. The transmission circuit 28 has a transmission antenna (not shown), modulates the carrier based on the transmission data Dt supplied from the CPU 24, and transmits the modulated signal as a response signal Sa through the transmission antenna. The carrier frequency of this response signal Sa is 200 MHz to 500 MHz.
[0025]
On the other hand, the control device 14 mounted on the actual vehicle 100 is constituted by, for example, a system LSI, and for example, as shown in FIG. 3, a power supply circuit 40, a CPU 42, a reception circuit 44, a transmission circuit 46, an input circuit 48, a first circuit It has a drive circuit 52 (for driving the actuator) and a second drive circuit 54 (for driving the main relay). Around the control device 14, at least a battery 60, a main switch 62, a seat actuator 64, a main relay 66, a start switch 70, and a transmission antenna 72 are installed.
[0026]
The main switch 62 has two fixed contacts 62a and 62b and one movable contact 62c. One fixed contact 62a is connected to the battery 60, and the other fixed contact 62b is connected to the main relay 66.
[0027]
A start switch 70 is connected to the input circuit 48, and the ON / OFF state of the start switch 70 is supplied to the CPU 42 through the input circuit 48.
[0028]
In the first embodiment, a scooter as shown in FIG. The actual vehicle 100 has a handlebar 102, a front wheel 104, a rear wheel 106, and an openable and closable seat 108 on which a user sits. Below this seat 108, there is a space in which a helmet (not shown) can be stored. Usually, when not riding, a helmet is stored in the space.
[0029]
In the first embodiment, the start switch 70 is provided inside the seat 108 as shown in FIGS.
[0030]
Specifically, as shown in FIG. 5, the sheet 108 has a bottom plate 110 made of, for example, metal or synthetic resin at the bottom, and a urethane material 114 is filled between the bottom plate 110 and the skin 112. Have been.
[0031]
The start switch 70 is housed in a housing space 116 formed in the urethane material 114, and a housing 118 of the start switch 70 is fixed to the bottom plate 110 by, for example, screws. The start switch 70 is provided inside the seat 108 and at a position corresponding to, for example, a portion of the left side of the seat 108 where the user touches the seat 108 when the user opens the seat 108.
[0032]
The operator 70a of the start switch 70 faces the back surface of the skin 112a on the left side of the seat 108. The distance between the tip of the operation element 70a and the back surface of the skin 112a is set such that the start switch 70 is turned ON when the user presses the skin 112a on the left side of the sheet 108 to open the sheet 108. Is set to In the above-described example, the case where the start switch 70 is provided on the left side of the seat 108 has been described. However, the start switch 70 may be provided on the right side of the seat 108 or on both sides of the left side and the right side.
[0033]
On the other hand, as shown in FIG. 3, the power supply circuit 40 in the control device 14 supplies power from the battery 60 to the CPU 42, the receiving circuit 44, the transmitting circuit 46, and the like.
[0034]
The receiving circuit 44 has a receiving antenna (not shown), receives the response signal Sa and the like transmitted from the electronic key 12 through the receiving antenna, extracts the signal from a carrier wave, and demodulates the signal. The demodulated signal is supplied to the CPU 42.
[0035]
The CPU 42 executes at least three programs (a request signal generation unit 80, a response signal comparison unit 82, and a monitoring unit 84).
[0036]
The request signal generation means 80 reads request data Dr (data that is the source of the request signal Sr) from a ROM (not shown) based on the ON operation of the start switch 70 and outputs the request data Dr to the transmission circuit 46.
[0037]
The transmission circuit 46 modulates a carrier based on the request data Dr supplied from the CPU 42 and transmits the modulated carrier as a request signal Sr through the transmission antenna 72.
[0038]
As shown in FIGS. 6A and 6B, the transmittable range of the request signal Sr is a spherical range having a radius of 1 to 1.5 m around the transmitting antenna 72 mounted on the actual vehicle 100 (circle A in FIGS. 6A and 6B). ), Which is narrower than the transmittable range of the response signal Sa (a range of several m radius around the electronic key 12).
[0039]
Therefore, when assuming, for example, a scooter as the actual vehicle 100, it is necessary to ensure that the communication with the electronic key 12 carried by the user can be reliably performed during the boarding operation, the operation of opening the seat 108, and the like. 6A and 6B, it is preferable to install the transmitting antenna 72 near the center of the actual vehicle 100, for example.
[0040]
Here, the vicinity of the center of the actual vehicle 100 is, for example, a line segment 120 connecting the center 104 a of the front wheel 104 and the center 106 a of the rear wheel 106. It is a range from the point P1 to the point P2 of 3/4. This applies to a motorcycle type not shown. In the present embodiment, transmitting antenna 72 is provided near the front of seat 108.
[0041]
The response signal matching unit 82 checks whether the signal supplied from the receiving circuit 44 is the response signal Sa. If the signal is the response signal Sa, the ID data included in the response signal Sa is not shown. It is checked whether it matches the ID data registered in the memory.
[0042]
The monitoring unit 84 monitors whether or not the response signal Sa has arrived (whether or not an ID match has been detected by the response signal matching unit 82) based on the output of the request signal Sr. The request signal generating means 80 waits for the input of the response signal Sa from the time when the request data Dr is output, and outputs the unlock signal to the first drive circuit 52 when the response signal Sa arrives within a predetermined time. , And outputs an ON signal to the second drive circuit 54.
[0043]
The first drive circuit 52 drives the actuator 64 based on the input of the unlock signal from the CPU 42 to release the locked state of the handle 102 and the seat 108. By this release, steering with the handle 102 becomes possible, and the seat 108 is lifted slightly upward, so that the user can easily recognize that the locked state of the handle 102 and the seat 108 is released.
[0044]
The second drive circuit 54 is turned on based on the input of the ON signal from the CPU 42, and then, when the main switch 62 is turned on to turn on the main relay 66, the engine is started, The vehicle is ready to run.
[0045]
When the main switch 62 is turned off, the main relay 66 is turned off, and the engine is stopped at the same time. When, for example, the helmet is stored in a space (not shown) below the seat 108 and a locking operation is performed, for example, the handle 102 and the seat 108 are operated in a locked state, the collation operation of the response signal Sa in the control device 14 is stopped. Accordingly, the second drive circuit 54 is turned off.
[0046]
Next, a typical processing operation of the electronic key system 10A according to the first embodiment will be described with reference to timing charts of FIGS. 7A to 7E. The request signal Sr is a signal having a pulse train based on the request data Dr, and the response signal Sa is a signal having a pulse train based on data including ID data. , Each signal is described as a one-pulse signal.
[0047]
First, at time t1 in FIG. 7A, when the user operates the start switch 70 while holding the electronic key 12, a request signal Sr is transmitted from the control device 14 as shown in FIG. 7C (see time t2). , Communication with the electronic key 12 is started.
[0048]
When the user has the electronic key 12, the request signal Sr is received through the receiving circuit 26 (see FIG. 2) of the electronic key 12. The electronic key 12 transmits a response signal Sa based on the reception of the request signal Sr as shown in FIG. 7D (see time point t3). The response signal Sa is supplied to the CPU 42 through the receiving circuit 44 (see FIG. 3) in the control device 14, and the ID data included in the response signal Sa is collated. When it is determined that the ID data matches, the locked state of the handle 102 and the seat 108 is released (unlocked) through the control device 14 and the first drive circuit 52 as shown in FIG. t4). At this time, the second drive circuit 54 turns ON.
[0049]
Subsequently, at time t5 in FIG. 7B, when the main switch 62 is turned on, the engine is started and the vehicle is ready to run.
[0050]
Thus, in the electronic key system 10A according to the first embodiment, the activation switch 70 is provided in the seat 108. Normally, when the user gets on the actual vehicle 100, an operation of taking out the helmet stored under the openable seat 108 is performed. At this time, an operation of gripping the sheet 108 and lifting the sheet 108 is performed. In this operation, since the start switch 70 can be easily operated, the operability related to the activation of the electronic key system 10A is improved. Can be done.
[0051]
In addition, since the start switch 70 is installed at a position where it cannot be seen from the outside, it is difficult for anyone other than an authorized user to easily find the start switch 70, which is effective in preventing theft.
[0052]
In particular, in the first embodiment, since the operating element 70a of the start switch 70 is provided so as to face the back surface of the skin 112 of the sheet 108, the start switch The start switch 70 can be easily operated by pressing a portion corresponding to a portion where the operation element 70a of 70 is located.
[0053]
That is, when opening the seat 108, two operations (two behaviors) of operating the start switch 70 to release the locked state of the seat 108 and then lifting the seat 108 are necessary. However, since the operator 70a of the start switch 70 is provided so as to be opposed to the back surface of the skin 112a on the left side of the sheet 108, for example, when opening the sheet 108, the start switch 70 , The operation from the operation of the activation switch 70 to the lifting of the seat 108 can be performed in one behavior, which is convenient.
[0054]
As described above, the start switch 70 can be a mechanical contact type switch, a capacitance type touch switch, a switch using the principle of a piezoelectric element, a switch using a Hall element, or the like. Can be used.
[0055]
Next, an electronic key system 10B according to a second embodiment will be described with reference to FIGS. Note that members and means corresponding to those in FIGS. 2 and 3 are denoted by the same reference numerals, and redundant description thereof will be omitted.
[0056]
The electronic key 12 in the electronic key system 10B according to the second embodiment has substantially the same configuration as the electronic key 12 (see FIG. 2) according to the first embodiment, as shown in FIG. , An operation switch 150.
[0057]
Further, the CPU 24 executes at least one program (request signal generation means 152). The request signal generating means 152 is started based on the ON operation of the operation switch 150, reads out ID data recorded in a ROM (not shown), adds an attribute indicating a response to the ID data, and adds the ID to the transmission circuit as transmission data Dt. 28. The transmission circuit 28 has a transmission antenna (not shown), modulates a carrier based on the transmission data Dt supplied from the CPU 24, and transmits the modulated signal as a request signal Sq through the transmission antenna. The carrier frequency of the request signal Sq is 200 MHz to 500 MHz.
[0058]
On the other hand, the control device 14 mounted on the actual vehicle 100 has substantially the same configuration as the control device 14 according to the first embodiment (see FIG. 3) as shown in FIG. And the fact that the transmitting antenna 72 does not exist, the point that the switching circuit 160 that selectively stops the supply of power to the receiving circuit 44 is provided, and the ON signal So and the intermittent pulse signal Sk are output to the switching circuit 160. The difference is that a switching control circuit 154 for controlling ON / OFF of the switching circuit 160 is provided.
[0059]
The receiving circuit 44 has a receiving antenna (not shown), receives the request signal Sq and the like transmitted from the electronic key 12 through the receiving antenna, extracts the request signal Sq from the carrier wave, and demodulates the signal. The demodulated signal is supplied to the CPU 42.
[0060]
The CPU 42 executes at least three programs (a request signal collating unit 156, a monitoring unit 84, and a clock unit 158).
[0061]
The request signal matching unit 156 checks whether the signal supplied from the receiving circuit 44 is the request signal Sq. If the signal is the request signal Sq, the ID data included in the request signal Sq is not shown. It is checked whether it matches the ID data registered in the memory.
[0062]
The monitoring unit 84 monitors the presence or absence of the request signal Sq (whether or not the ID match is detected by the request signal matching unit 156), and detects the request signal Sq from the electronic key 12 carried by an authorized user. Then, an unlock signal is output to the first drive circuit 52 to release the locked state of the handle 102 and the seat 108, and at the same time, the second drive circuit 54 is turned on. Thereafter, when the main switch 66 is turned ON by turning on the main switch 62, the engine is started and the vehicle is ready to run.
[0063]
When the main switch 62 is turned off, the main relay 66 is turned off, and the engine is stopped at the same time. At this time, the second drive circuit 54 is turned off.
[0064]
The timer 158 is used when the start switch 70 is turned on, when the main switch 62 is in the ON state, and when the main switch 62 is turned off until the timer 158 counts a predetermined value. In the period, continuation instruction signal Sc is output to switching control circuit 154.
[0065]
The timing means 158 counts a reference clock from a clock generator (not shown) from the time when the main switch 62 is turned off, and counts to a predetermined value (for example, when two days or one week has elapsed). Outputs an intermittent instruction signal Sp to the switching control circuit 154.
[0066]
The switching control circuit 154 outputs an ON signal So to the switching circuit 160 during a period in which the continuation instruction signal Sc is supplied from the timer 158. The switching circuit 160 turns on the switch 162 based on the supplied ON signal So, whereby the power supply to the receiving circuit 44 is always continued.
[0067]
When the intermittent instruction signal Sp is supplied from the timer 158, the switching control circuit 154 generates an intermittent pulse signal Sk whose attribute is intermittently switched between ON and OFF, and outputs the signal to the switching circuit 160. The switching circuit 160 intermittently repeats the ON operation and the OFF operation based on the supplied intermittent pulse signal Sk. As a result, the power supply to the receiving circuit 44 becomes intermittent, and the control device 14 shifts to the power saving operation mode.
[0068]
Then, in the power saving operation mode, when the start switch 70 is turned ON, the continuation instruction signal Sc is output from the timer 158 to the switching control circuit 154, whereby the power supply to the receiving circuit 44 is constantly continued. You.
[0069]
In the electronic key system 10B according to the second embodiment, when the actual vehicle is not started for a predetermined period, power supply to the receiving circuit 44 is intermittently performed until the start switch 70 is turned on thereafter. Therefore, power consumption during standby can be reduced.
[0070]
Next, an electronic key system 10C according to a third embodiment will be described with reference to FIG. Note that members and means corresponding to those in FIG. 9 are denoted by the same reference numerals, and redundant description thereof will be omitted.
[0071]
The electronic key 12 used in the electronic key system 10C according to the third embodiment is the same as the electronic key 12 according to the above-described second embodiment (see FIG. 8).
[0072]
The control device 14 also has substantially the same configuration as the control device 14 according to the above-described second embodiment (see FIG. 9), except that the switching control circuit 154 outputs an ON signal So and an OFF signal Sf. .
[0073]
That is, the time counting means 158 counts a predetermined value by the time counting means 158 when the start switch 70 is turned on, when the main switch 62 is turned on, and after the main switch 62 is turned off. During this period, the continuation instruction signal Sc is output to the switching control circuit 154.
[0074]
The timer 158 counts a reference clock from a clock generator (not shown) from the time when the main switch 62 is turned off, and outputs a stop instruction signal Ss to the switching control circuit 154 when the count reaches a predetermined value. I do.
[0075]
The switching control circuit 154 outputs an ON signal So to the switching circuit 160 during the period in which the continuation instruction signal Sc is supplied from the timing unit 158, whereby the power supply to the receiving circuit 44 is always continued. Will be.
[0076]
The switching control circuit 154 outputs an OFF signal Sf at the time when the stop instruction signal Ss is supplied from the timing unit 158. The switching circuit 160 turns off the switch 162 based on the supplied OFF signal Sf, whereby the power supply to the receiving circuit 44 is completely stopped.
[0077]
When the start switch 70 is turned on while the power supply to the receiving circuit 44 is stopped, a continuation instruction signal Sc is output from the timing unit 158 to the switching control circuit 154, whereby the receiving circuit 44 Power supply is always continued.
[0078]
In the electronic key system 10C according to the third embodiment, when the actual vehicle is not started for a predetermined period, power is not supplied to the receiving circuit 44 at all until the start switch 70 is turned on. Therefore, power consumption during standby can be significantly reduced.
[0079]
Moreover, communication with the outside (communication with the electronic key 12) is not performed unless the predetermined start switch 70 is turned ON, and the start switch 70 cannot be easily found by anyone other than the authorized user. It is also effective in preventing theft.
