DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, several embodiments in which the electronic key system for a vehicle according to the present invention is applied to, for example, a system for a motorcycle will be described with reference to FIGS.
[0017]
As shown in FIG. 1, the electronic key system 10 according to the present embodiment includes an electronic key 12 carried by a user (user) and a control device 14 mounted on an actual vehicle 100 (see FIG. 6). The electronic key 12 has a key shape with an IC chip incorporated therein, and an electronic key 12 with a card shape and an IC chip incorporated therein. When applied as a system, the shape of a card is used. In the present embodiment, description will be made assuming an electronic key 12 having a card shape.
[0018]
The electronic key 12 has the shape of a card as described above, and has a battery 20, a power supply circuit 22, a CPU 24, a reception circuit 26, and a transmission circuit 28 therein as shown in FIG.
[0019]
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 it from the carrier wave, and demodulates it. The demodulated signal is supplied to the CPU 24. The carrier frequency of the request signal Sr is 100 kHz to 300 kHz.
[0020]
The CPU 24 executes at least two computer programs (request signal checking means 30 and response signal generating means 32). The request signal checking unit 30 checks whether the signal supplied from the receiving circuit 26 is the request signal Sr. If the request signal Sr is the request signal Sr, the control is transferred to the response signal generating unit 32. The response signal generation means 32 reads ID data recorded in a ROM (not shown) based on a request from the request signal verification means 30, adds an attribute indicating a response to this ID data, and transmits it as transmission data Dt. To 28. The transmission circuit 28 has a transmission antenna (not shown), modulates a carrier wave based on 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 the response signal Sa is 200 MHz to 500 MHz.
[0021]
On the other hand, the control device 14 mounted on the actual vehicle 100 is constituted by, for example, a system LSI, and as shown in FIG. 3, for example, a power supply circuit 40, a CPU 42, a receiving circuit 44, a transmitting circuit 46, an input circuit 48, a first circuit. It has a drive circuit 52 (for actuator drive), a second drive circuit 54 (for main relay drive), and a third drive circuit 56 (for LED drive). Around the control device 14, at least a battery 60, a main switch 62, an actuator 64, a main relay 66, a warning lamp 68 (LED), a start switch 70, and a transmission antenna 72 are installed.
[0022]
The main switch 62 has two fixed contacts 62 a and 62 b and one movable contact 62 c, one fixed contact 62 a is connected to the battery 60, and the other fixed contact 62 b is connected to the input circuit 48 and the main relay 66. Has been.
[0023]
In addition to the other fixed contact 62 b of the main switch 62, an activation switch 70 is connected to the input circuit 48. The ON / OFF state of the start switch 70 and the ON / OFF state of the main switch 62 are supplied to the CPU 42 through the input circuit 48.
[0024]
The start switch 70 can be set to any one of the operation switches used for starting the engine of the actual vehicle 100, safety during traveling, and stopping the engine of the actual vehicle 100, for example. Specifically, when the actual vehicle 100 is a motorcycle type as shown in FIG. 4, a lighting dimmer switch 104, a clutch switch 106, a winker switch 108, a horn switch 110, a front brake switch installed around the handle 102 Any one of 112, the hazard switch 114, and the starter switch 116 can be set as the activation switch 70.
[0025]
When the actual vehicle 100 is a scooter type as shown in FIG. 5, the activation switch 70 includes a lighting dimmer switch 122, a rear brake switch 124, a winker switch 126, a horn switch 128, Any one of the front brake switch 130, the hazard switch 132, and the starter switch 134 can be set.
[0026]
For example, when the user purchases the actual vehicle 100, the activation switch 70 is determined in advance by a user, for example, by a contract with a dealer, and wiring is performed at the factory based on the determined items. For example, wiring for connecting the switch determined as the start switch 70 and the input circuit 148 of the control device 14 is performed at the factory.
[0027]
The start switch 70 may be any of various switches installed around the handles 102 and 120 as described above. For example, in a scooter, as shown in FIG. 6, the seat 140 or the vicinity of the seat 140 is used. An activation switch 70 may be provided.
[0028]
Below the seat 140 is a space in which a helmet (not shown) can be stored. Usually, when not riding, the helmet is stored in the space.
[0029]
Further, around the rear part of the seat 140, at least a handle 142 (referred to as a seat handle 142 for distinguishing from the handle 120 steered by the driver) used for manually opening and closing the seat 140 is provided. Yes.
[0030]
Accordingly, examples of the installation location of the activation switch 70 include the seat handle 142 and the interior of the seat 140. In the case where the activation switch 70 is provided on the seat handle 142, it is preferable that the activation switch 70 be provided on a portion of the seat handle 142 that is gripped by a hand when the user opens the seat 140. When the activation switch 70 is provided inside the seat 140, it is preferable to embed the activation switch 70 in a position corresponding to a portion that the user puts on when opening the seat 140.
[0031]
Thereby, in order to take out the helmet, the user performs an operation of opening the seat 140 and at the same time, the start switch 70 is turned on, so that the operability related to the start of the electronic key system 10 can be improved.
[0032]
On the other hand, the power supply circuit 40 in the control device 14 supplies the power from the battery 60 to the CPU 42, the reception circuit 44, the transmission circuit 46, and the like.
[0033]
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 it from the carrier wave, and demodulates it. The demodulated signal is supplied to the CPU.
[0034]
The CPU 42 executes at least four programs (request signal generation means 80, response signal collation means 82, monitoring means 84, and peripheral instruction means 86).
[0035]
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 the main switch 62 and outputs the request data Dr to the transmission circuit 46. Further, the request signal generation means 80 reads request data Dr from the ROM and outputs it to the transmission circuit 46 at regular intervals after the engine is started. This fixed time is set to any time of 10 to 100 sec in consideration of the consumption of the battery 20 in the electronic key 12.
[0036]
The transmission circuit 46 modulates a carrier wave based on the request data Dr supplied from the CPU 42 and transmits the modulated carrier wave as a request signal Sr through the transmission antenna 72.
[0037]
As shown in FIGS. 7A and 7B, the transmittable range of the request signal Sr is a spherical range having a radius of 1 to 1.5 m centering on the transmission antenna 72 attached to the actual vehicle 100 (circle A in FIGS. 7A and 7B). And a narrower range than the transmission possible range of the response signal Sa (range of radius m around the electronic key 12).
[0038]
Therefore, as shown in FIGS. 7A and 7B, when assuming a scooter in which a helmet storage space (not shown) is installed under the seat 140 as the actual vehicle 100, for example, communication with the electronic key 12 carried by the user is performed. In order to ensure that the electronic key 12 can be reliably operated when the operation is performed on the actual vehicle 100, when the operation of opening the seat 140 is performed, and when the electronic key 12 is stored in the helmet storage space, for example, the actual vehicle It is preferable to install the transmission antenna 72 near the center of 100.
[0039]
Here, the vicinity of the center of the actual vehicle 100 refers to a line segment (wheel base) 154 connecting the center 150a of the front wheel 150 and the center 152a of the rear wheel 152. For example, the wheel base 154 is based on the center 150a of the front wheel 150. Is a range from the upper part to the lower part of the actual vehicle 100 within a range from a point P1 of 1/4 to a point P2 of 3/4. In the present embodiment, the transmission antenna 72 is installed in the vicinity of the front portion of the seat 140.
[0040]
Next, the response signal collating unit 82 collates whether or not 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 Then, it is verified whether or not it matches the ID data registered in the memory (not shown).
[0041]
Based on the output of the request signal Sr, the monitoring unit 84 monitors whether or not the response signal Sa has arrived (whether or not the ID match in the response signal matching unit 82 has been detected). When the request signal generation means 80 waits for input of the response signal Sa from the time when the request data Dr is output and the response signal Sa does not arrive within a predetermined time (the ID match is detected by the response signal verification means 82) If not, the count value is updated by +1. Then, a warning signal Se is output to the third drive circuit 56 when the count value becomes equal to or greater than a predetermined value.
[0042]
In particular, when the response signal Sa does not arrive within a predetermined time from when the request data Dr is output based on the ON operation of the start switch 70 and the main switch 62, the warning signal Se is sent to the third drive at that stage. Output to the circuit 56.
[0043]
Further, the monitoring unit 84 activates the peripheral instruction unit 86 when the response signal Sa arrives within a predetermined time from the time when the request data Dr is output based on the ON operation of the activation switch 70. The peripheral instruction means 86 outputs a lock release signal to the first drive circuit 52 based on a request (unlock) from the monitoring means 84, and further outputs an ON signal to the second drive circuit 54.
[0044]
The first drive circuit 52 drives the actuator 64 based on the input of the lock release signal from the CPU 42 and releases the lock state of the handle 120 and the seat 140.
[0045]
The second drive circuit 54 is turned on based on the input of the ON signal from the CPU 42, and then the engine starts when the main relay 66 is turned on by the main switch 62 being turned on. The vehicle is ready to run.
[0046]
The third drive circuit 56 drives the warning lamp 68 based on the input of the warning signal Se from the CPU 42, and the warning lamp 68 emits light. As this warning lamp 68, for example, an LED can be used.
[0047]
When the main switch 62 is turned off, the main relay 66 is turned off and the engine is also stopped simultaneously. When the locking operation, for example, the handle 120 or the seat 140 is operated in the locked state, the verification operation of the response signal Sa in the control device 14 is stopped, and the second drive circuit 54 is also turned OFF.
[0048]
Next, processing operations of the electronic key system 10 according to the present embodiment will be described with reference to the timing charts of FIGS. 8A to 8E. 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. However, in FIGS. 8A to 8E, the description is simplified. In order to achieve this, each is shown as a one-pulse signal.
[0049]
First, at normal time, when the user operates the activation switch 70 with the electronic key 12 held at time t1 in FIG. 8A, a request signal Sr is transmitted from the control device 14 as shown in FIG. 8C. (See time t2) Communication with the electronic key 12 is started.
[0050]
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. Based on the reception of the request signal Sr, the electronic key 12 transmits a response signal Sa as shown in FIG. 8D (see time 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 match, the handle 120 and the seat 140 are unlocked (unlocked) through the control device 14 and the first drive circuit 52 as shown in FIG. t4). By releasing the lock, the steering wheel 120 can be steered and the seat 140 is lifted slightly upward, so that the user can easily recognize that the handle 120 and the seat 140 are unlocked. At this time, the second drive circuit 54 is turned ON.
[0051]
Subsequently, at time t5 in FIG. 8B, when the user operates the main switch 62 with the electronic key 12 held, a request signal Sr is transmitted from the control device 14 as shown in FIG. 8C (see time t6). ), Communication with the electronic key 12 is performed.
[0052]
When the user has the electronic key 12, as described above, the electronic key 12 transmits the response signal Sa as shown in FIG. 8D based on the reception of the request signal Sr (see time t7). The response signal Sa is supplied to the CPU 42 through the receiving circuit 44 in the control device 14, and the ID data included in the response signal Sa is collated. If it is determined that the ID data match, the next step, that is, The process proceeds to a step of outputting the request signal Sr at every constant time τ.
[0053]
From this stage, the user is traveling in the actual vehicle 100, for example, and during this traveling, the request signal Sr is output from the control device 14 every predetermined time τ. That is, communication with the electronic key 12 is performed at regular time intervals τ, and a response signal Sa is output from the electronic key 12 at substantially regular intervals τ.
[0054]
The above-described processing operation shows the processing from when the user has the electronic key to get on the actual vehicle 100 until the user travels with the actual vehicle 100. Next, there is no electronic key 12 when the actual vehicle 100 is activated. The processing operation in the case of detecting is described briefly.
[0055]
First, when the user does not have the electronic key 12 and the start switch 70 is turned on, a request signal Sr is transmitted from the control device 14, and the control device 14 responds to the output request signal Sr. The signal Sa is not received. As a result, the warning signal Se is output from the monitoring means 84 to the third drive circuit 56, and thereby the warning lamp 68 is turned on. Of course, in this case, processing such as unlocking of the handle 120 and the seat 140 is not performed.
[0056]
The user notices that he / she does not have the electronic key 12 by turning on the warning lamp 68, and can avoid starting the engine in a state where the electronic key 12 is not held in advance.
[0057]
Next, the processing operation when it is detected that the electronic key 12 is not present when the engine of the actual vehicle 100 is started will be briefly described.
[0058]
First, when the user operates the start switch 70 with the electronic key 12 held, a request signal Sr is transmitted from the control device 14 and communication with the electronic key 12 is started. By this communication, the ID data included in the response signal is collated, and when it is determined that the ID data match, the handle 120 and the seat 140 are unlocked.
[0059]
Subsequently, when the user turns on the main switch 62 without noticing that the electronic key 12 has been dropped, for example, the request signal Sr is transmitted from the control device 14. The response signal Sa to the signal Sr is not received. As a result, the warning signal Se is output from the monitoring means 84 to the third drive circuit 56, and thereby the warning lamp 68 is turned on.
[0060]
The user notices that the electronic key 12 has been dropped by turning on the warning lamp 68, and the loss of the electronic key 12 is avoided in advance.
[0061]
Next, the processing operation when it is detected that there is no electronic key 12 while the actual vehicle 100 is traveling will be briefly described.
[0062]
First, the processing from the ON operation of the start switch 70 to the ON operation of the main switch 62 is the same as the processing from time t1 to time t7 in FIGS. 8A to 8E.
[0063]
When the engine is started based on the ON operation of the main switch 62, the process proceeds to the step of outputting the request signal Sr every predetermined time τ as described above. From this stage, the user is traveling in the actual vehicle 100, for example, and during this traveling, the request signal Sr is output from the control device 14 every predetermined time τ.
[0064]
For example, when the electronic key 12 is dropped during traveling in the actual vehicle 100, the control device 14 does not receive the response signal Sa. The monitoring unit 84 updates the count value by +1 when the response signal Sa is not received within a predetermined time from the output time point of the request data Dr. In the process of sequentially outputting the request signal Sr, the warning signal Se is output from the monitoring unit 84 to the third drive circuit 56 when the count value becomes equal to or greater than the predetermined value. Will light up.
[0065]
The user notices that the electronic key 12 has been dropped by turning on the warning lamp 68, and the loss of the electronic key 12 is avoided in advance.
[0066]
Thus, in the electronic key system 10 according to the present embodiment, the transmission antenna 72 (transmitting the request signal Sr) of the control device 14 is installed near the center of the actual vehicle 100. The request signal Sr is output from the vicinity of the center of the actual vehicle 100.
[0067]
Therefore, it is possible to cover almost the entire area of the actual vehicle 100 as the transmittable range. As a result, it is possible to reliably communicate with the electronic key 12 when the user enters the actual vehicle 100, during traveling, when the seat 140 is opened and closed, and when the electronic key 12 is stored in the helmet storage space. it can. In this case, since only one transmission antenna 72 has to be installed, communication with the electronic key 12 in all the above-described situations can be realized without incurring an increase in cost, weight, installation space, or the like.
[0068]
In addition, there is a case where a bag containing the electronic key 12 is put in the helmet storage space at the lower part of the seat 140, but even in this case, the communication between the control device 14 and the electronic key 12 is surely performed. So-called closing (state in which the lock of the seat 140 cannot be released while the electronic key 12 is stored in the helmet storage space) can be avoided.
[0069]
Next, two modified examples of the electronic key system 10 according to the present embodiment will be described with reference to FIGS.
[0070]
First, the electronic key system 10a according to the first modification has substantially the same configuration as the electronic key system 10 according to the first embodiment described above, but as shown in FIG. Is different in that a transmission unit 160 is installed.
[0071]
As shown in FIG. 10, the transmission unit 160 separates the transmission circuit 46 from the control device 14 configured by a system LSI to form one electronic component 162, and electrically connects the electronic component 162 to the transmission antenna 72. And unitized.
[0072]
The electronic key system 10b according to the second modified example has substantially the same configuration as that of the electronic key system 10 according to the first embodiment described above, but as shown in FIG. The difference is that the unit 170 is installed.
[0073]
As shown in FIG. 12, the transmission / reception unit 170 separates the reception circuit 44 and the transmission circuit 46 from the control device 14 configured by a system LSI, and the reception circuit 44 and the transmission circuit 46 are integrated. One electronic component 172, and the transmission circuit 46 of the electronic component 172 and the transmission antenna 72 are electrically connected to form a unit.
[0074]
Whether the electronic key system 10 according to the present embodiment or the electronic key systems 10a and 10b according to the first and second modifications described above is adopted depends on the size of the actual vehicle 100, the wiring path, the transmission antenna 72, etc. What is necessary is just to select suitably in consideration of installation space.
[0075]
In addition, the vehicle electronic key system according to the present invention is not limited to the above-described embodiment, and can of course have various configurations without departing from the gist of the present invention.
[0076]
【The invention's effect】
