Description

  The present invention relates to an execution priority setting apparatus for an electronic key system that sets execution priorities in various systems executed in the electronic key system.

  Conventionally, as a vehicle key system, an electronic key that wirelessly transmits a unique ID code possessed by a key is used as a vehicle key, and an ID verification is performed by comparing the ID code transmitted from the electronic key with that of the vehicle. Key systems are widely used. This type of electronic key system includes a wireless key system that performs various vehicle operations by operating a door locking / unlocking button provided on the electronic key and wirelessly transmitting an operation request (wireless signal) to the vehicle. Is widely spread. One type of this wireless key system is, for example, a wireless door lock system in which door lock locking / unlocking is remotely controlled by a key. This wireless signal is a radio signal including a unique ID code of the wireless key and a function code corresponding to the button operated on the key.

  Further, in recent vehicles, various systems for improving convenience other than this type of wireless door lock system tend to be mounted as wireless key systems. Other systems of this type include, for example, a power slide door opening and closing system that automatically opens and closes a vehicle sliding door by remote operation of a key, and a tailgate opening and closing system that automatically raises and lowers a vehicle tailgate by remote operation of a key. . When this type of system is installed in a vehicle, the electronic key is provided with a dedicated button for the system, and when this button is pressed, a unique ID of the key is provided as in the wireless key system. A wireless signal including a code and a function code corresponding to the operation button is sent to the vehicle, and various signals are operated by this signal.

  By the way, when various systems are mounted on one vehicle in this way, while a wireless signal of a certain system is being transmitted, that is, while an operation of a certain system is being executed, When a button of another system other than the execution system is operated, an operation start request of another system is entered, and the system execution may overlap. In order to cope with such a situation, for example, Patent Document 1 discloses a technique for preferentially executing a system operation in accordance with a newly received button operation when an operation start request of another system is received during execution of one system. It is disclosed. That is, this prior art is a logic that prioritizes the system operation of the button operation when an operation start request of another system is received during the execution of one system operation.

Japanese Patent No. 3426547

  By the way, among a plurality of existing systems, there is a highly important system that needs to reliably execute the operation of the system from the start to the completion when the button is operated once. As this system, for example, there is a system in which the user's intention to operate is highly reflected, and examples thereof include a power slide door opening / closing system and a tailgate opening / closing system. However, in the logic to execute the button-operated system with the highest priority as in the prior art, if the wireless signal of the system with high importance is being transmitted, if the button operation is rushed, other buttons are operated. If this happens, the signal transmission of the highly important system is stopped halfway, and the previous system falls into a state where it does not operate. Therefore, some countermeasure has been desired.

  An object of the present invention is to provide an execution priority setting device for an electronic key system that can more reliably execute operations of a plurality of systems having high importance until the operation is completed.

  In order to solve the above problem, in the present invention, when an electronic key communication destination is provided with a plurality of systems, and an operation execution request notification including an ID code is transmitted from the electronic key to the communication destination, the ID Execution priority order of the electronic key system in which the system operates in accordance with the operation execution request notification at that time among a plurality of the systems on condition that the code matches with that of the communication destination and the key verification is established In the setting device, when a plurality of executions of the system are overlapped, a priority setting table in which which of the plurality of systems is to be executed preferentially is set, and a higher priority is given priority. The gist is that priority processing means for processing is provided.

  According to this configuration, when a plurality of system executions are performed, for example, when an operation start request relating to another system is received from the electronic key during operation of a predetermined system, the priority determined from the priority setting table is set. A high system is preferentially executed. For this reason, even if multiple executions of the system overlap, it is possible to execute the operation of each system by the control taking the importance into consideration, such as the operation is executed first from the system with the higher priority. It becomes possible.

  In the present invention, when the priority processing means receives an operation start request of another system during the operation of the system, if the priority of the newly received request is higher, the priority processing means stops the system that is executing the operation. The system operation according to the newly accepted operation start request is executed with priority, and conversely, if the priority of the system that is executing the operation is higher, the system that is executing the operation is continuously executed. The gist is to do.

  According to this configuration, for example, when a new operation start request for another system is received from the electronic key during system operation execution, if the execution priority of the system being executed is higher, it is newly received at this time. The system in accordance with the requested operation start request is not executed first, but the operation being executed is preferentially executed. For this reason, it is possible to prevent a situation in which the execution of a system with a high priority having a high priority level is stopped in the middle of an operation due to reception of a new operation start request.

  In the present invention, the priority processing means is configured such that when the new request is newly received during the system execution, the newly received request has a lower priority than the running system and the system execution is continued. The execution flag of the newly accepted operation start request is held in its own memory, and after the operation of the system being executed is completed, an operation is performed by operating based on the execution flag of the memory. The gist of the present invention is to execute the operation of the newly accepted system after waiting for the end of the operation of the system.

  According to this configuration, when a new operation start request is received from the electronic key during execution of the predetermined system, even when the operation of the running system is preferentially executed, the newly received system is changed to the system that is executing the operation. It is possible to execute after the operation is completed. For this reason, when operating a new system, the operation of sending an operation execution request notification from the electronic key is not necessary, so that the convenience of the system can be enhanced.

  In the present invention, the priority order of the systems in the priority order setting table is set such that the order is assigned at least at two or more high and low levels by allowing a plurality of systems to be assigned to the same order. The gist.

  According to this configuration, for example, a plurality of these systems are arranged such that a high-priority system group that does not want to stop operation in the middle is in a high rank, and a low-importance system group that may stop operation in the middle is in a low rank. It is possible to assign and set for each predetermined rank. For this reason, it is not necessary to set the priorities of these systems in a unique order such as first, second,..., So that the priorities can be set in a flexible format.

  In the present invention, when a plurality of executions of the system are overlapped, the priority processing means forcibly stops the running system and newly accepts the operation start request. The gist is to preferentially execute the operation of the system.

  According to this configuration, if execution of systems having the same priority overlaps, the system being executed is forcibly stopped, and the system that has newly accepted the operation start request is preferentially executed. For this reason, even if execution of systems having the same priority is overlapped, these systems can be operated without any problem.

  In the present invention, the priority processing means is provided in the electronic key, and during execution of one signal of the operation execution request notification, the system execution is overlapped by receiving another operation execution request notification transmission request. If the priority of the newly received outgoing request is higher, the outgoing operation at that time is stopped and the operation execution request notification is sent according to the new outgoing request, and conversely, the operation execution request being sent If the priority of the notification is higher, the gist is to prioritize the execution of the system by continuing the transmission operation without accepting the request at this time.

  According to this configuration, since the function for giving priority to the execution of the system is provided on the electronic key side, it is not necessary to impose a special design change on the vehicle when this function is mounted on the vehicle.

  According to the present invention, it is possible to more reliably execute an operation of a plurality of systems having a high degree of importance until the operation is completed.

Hereinafter, an embodiment of an execution priority setting apparatus for an electronic key system embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, the vehicle 1 is an electronic device that performs key verification by wireless communication with an electronic key 2 that is used as a vehicle key, and executes various operations of the vehicle 1 on the condition that this key verification is established. A key system 3 is provided. In this case, the vehicle 1 includes a key verification device 4 that performs key verification with the electronic key 2, a door lock device 5 that manages door lock locking / unlocking of various doors of the vehicle 1, and a power state of the vehicle 1. (Power supply position) and an engine starting device 6 for managing the engine operating state are provided. The electronic key 2 is capable of narrow-range wireless communication with the vehicle 1, and transmits an ID code (key code) inherent to the electronic key 2 to the vehicle 1 by wireless communication to the vehicle 1. A key that can be verified. Further, the vehicle 1 corresponds to a communication destination.

  The electronic key system 3 includes a key operation free system that does not require individual key operations when the electronic key 2 transmits an ID code. The key operation free system includes a smart entry system as a function that does not require a key operation at the time of door lock / unlock operation. In this smart entry system, the vehicle 1 is provided with a verification ECU (Electronic Control Unit) 7 that performs key verification (ID verification) with the electronic key 2. The verification ECU 7 includes an out-of-vehicle LF transmitter 8 that transmits an LF (Low Frequency: about 130 kHz) signal outside the vehicle, an in-vehicle LF transmitter 9 that transmits the same LF signal into the vehicle, and an RF band (Radio Frequency). : About 312 MHz) is connected to the RF receiver 10 capable of receiving the signal. The verification ECU 7 is connected to the door lock device 5 and the engine starting device 6 via an in-vehicle LAN (Local Area Network) 11 that is one network in the vehicle.

  The electronic key 2 is provided with a communication control unit 12 that performs overall control of various operations of the electronic key 2. The communication control unit 12 includes a control IC (Integrated Circuit) having various devices such as a CPU (Central Processing Unit) 13 and a memory 14, and an ID code is registered in the memory 14 as a unique key code of the electronic key 2. Has been. The communication control unit 12 is connected to an LF receiver 15 capable of receiving an LF band radio signal and an RF transmitter 16 capable of transmitting an RF band radio signal. The communication control unit 12 sequentially monitors which type of radio signal is received by the LF receiver 15 and manages the operation of signal transmission from the RF transmitter 16.

  When the vehicle 1 is in a parked state, the verification ECU 7 intermittently transmits the LF band request signal Srq from the vehicle LF transmitter 8 to form the vehicle communication area of the request signal Srq around the vehicle, and the narrow area wireless communication (Hereinafter referred to as smart communication). When the electronic key 2 enters the outside communication area and receives the request signal Srq, the electronic key 2 responds to the request signal Srq and sends the ID signal Sid carrying the ID code registered in its own memory 14 to the RF band. Reply with the signal. When the smart communication (external communication) is established by receiving the ID signal Sid with the RF receiver 10, the verification ECU 7 compares the ID code registered in its own memory 17 with the ID code of the electronic key 2. , So-called smart verification (external verification). When the verification ECU 7 confirms that this external verification is established, the door lock device 5 permits or executes the door lock locking / unlocking operation. The ID signal Sid constitutes an operation execution request notification.

  In addition, the key operation free system has a one-push function that allows the engine (not shown) to be started / stopped by a simple switch operation without requiring an actual vehicle key operation during the engine start / stop operation. There is an engine start system. In this one-push engine start system, for example, when the driver enters the vehicle by a courtesy switch (not shown), the verification ECU 7 does not start from the previous LF transmitter 8, but this time the in-vehicle LF transmitter. A request signal Srq is transmitted from 9 to form an in-vehicle communication area throughout the vehicle. When the RF signal is received by the RF receiver 10 and the smart communication (in-vehicle communication) is established when the electronic key 2 enters the in-vehicle communication area and returns, the verification ECU 7 establishes the ID code and the electronic key registered in itself. ID collation, so-called smart collation (in-vehicle collation) is performed by checking the ID code of No. 2. When the verification ECU 7 confirms that the in-vehicle verification has been established, the verification ECU 7 permits the engine start device 6 to switch the power state.

  As a result, when the push momentary engine switch (not shown) is pushed while the brake pedal is depressed while the engine is in the stopped state, the engine that has been in the stopped state is switched to the activated state. When the engine is in a movable state, if the engine switch is pushed while the range position of the select lever is in the parking position (P range), the engine is now switched to a stopped state. Furthermore, when the engine is stopped and the brake pedal is not depressed and only the engine switch is pushed, the power state is repeatedly switched in the order of power off → ACC on → IG on every push operation.

  The electronic key system 3 includes a wireless key system that performs various vehicle operations such as door lock locking / unlocking by operating the buttons of the electronic key 2. In this wireless key system, when various buttons provided on the electronic key 2 are operated, a wireless signal Swl having a signal content corresponding to the operation button at that time is transmitted to the RF transmitter 16 by narrowband wireless communication (wireless communication). From the vehicle 1 to the vehicle 1 as an RF band signal. The wireless signal Swl includes an ID code which is a key code of the electronic key 2 and a function code for notifying what kind of vehicle operation has been instructed by a button operation. When the ID code in the wireless signal Swl matches the vehicle 1 and ID verification is established, the vehicle operation according to the function code included in the same wireless signal Swl is executed.

  This wireless key system includes a wireless door lock system that locks and unlocks the door lock by operating a button with the electronic key 2. In this case, when the lock button 18 is operated with the electronic key 2, a locking request is transmitted from the electronic key 2 as a wireless signal Swl as an RF band signal. This locking request is a wireless signal Swl having a function code that instructs the vehicle 1 to lock the door. When the verification ECU 7 receives this locking request by the RF receiver 10, if the ID code in the locking request is correct, the verification ECU 7 causes the door lock device 5 to lock the door lock according to the function code at this time. Further, when the unlock button 19 is operated with the electronic key 2, the unlocking request is transmitted from the electronic key 2 as a wireless signal Swl as an RF band signal. This unlocking request is a wireless signal Swl having a function code that instructs the vehicle 1 to unlock the door. When the unlocking request is received by the RF receiver 10, the verification ECU 7 causes the door lock device 5 to unlock the door lock according to the instruction of the function code at this time if the ID code in the unlocking request is correct. The wireless signal Swl constitutes an operation execution request notification.

  Further, the wireless key system includes a power slide door opening / closing system that automatically opens and closes a power slide door (not shown) of the vehicle 1 by a button operation with the electronic key 2. In this case, the vehicle 1 is provided with a power slide door device 20 that manages opening and closing of the power slide door. In the power slide door opening / closing system, when the power slide door open / close button 21 of the electronic key 2 is pressed for a long time (for example, 1 second) when the power slide door is closed, the power slide door automatically opens using a motor or the like as a drive source, When the power slide door opening / closing button 21 of the electronic key 2 is again pressed for a long time after the door is opened, the motor slides backward to automatically close the power slide door.

  When the power slide door open / close button 21 is operated for a long time, a power slide door operation request is transmitted as a wireless signal Swl as an RF band signal. This power slide door operation request is a wireless signal Swl having, as a function code, a content that instructs the vehicle 1 to execute the operation of the power slide door. When the verification slide ECU 7 receives the power slide door operation request by the RF receiver 10, if the ID code in the power slide door operation request is correct and the power slide door is fully closed, the verification ECU 7 The sliding door is opened. Further, when the verification ECU 7 receives the power slide door operation request by the RF receiver 10, if the ID code in the power slide door operation request is correct and the power slide door is in the open state, the verification ECU 7 Execute the sliding door closing operation.

  In addition to the power sliding door opening and closing system, systems using a wireless key system include, for example, a tailgate opening and closing system that automatically opens and closes a tailgate (not shown), a trunk opening and closing system that automatically opens and closes a luggage door (not shown), There are window opening and closing systems that automatically open and close windows (not shown) of vehicle side doors. The tailgate opening / closing system automatically opens and closes the tailgate by operating the tailgate opening / closing button 22 of the electronic key 2 to operate the tailgate device 23 of the vehicle 1. The trunk opening / closing system automatically opens and closes the trunk by operating the trunk opening / closing button 24 of the electronic key 2 to operate the trunk device 25 of the vehicle 1. In the window opening and closing system, the window of the side door is automatically opened and closed by operating the power window device 27 of the vehicle 1 by operating the window opening and closing button 26 of the electronic key 2.

  As shown in FIGS. 1 and 2, the electronic key system 3 of this example executes the operation of each system according to a predetermined priority order when the execution operations overlap between these systems of the vehicle 1. System priority order processing function is included. The system priority processing function of this example selectively executes transmission of RF signal operations one by one so that transmission operations of various RF band signals from the electronic key 2 (hereinafter referred to as RF signals) do not overlap. By doing so, a key-side management formula for managing execution of system operations on the so-called electronic key 2 side that avoids duplication of system execution is adopted.

  In this case, the memory 14 of the communication control unit 12 is provided with a priority order setting table 28 in which system execution priorities are set. As shown in FIG. 3, the priority setting table 28 is divided into three levels, for example, high, medium, and low, and the priorities of the various systems described above are allocated among these three levels. In this example, the power sliding door opening and closing system and the tailgate opening and closing system are set to high priority, the window opening and closing system and the trunk opening and closing system are set to medium priority, the key operation free system and the wireless door lock system, Is set to low priority.

  As shown in FIG. 2, the communication control unit 12 is provided with a system execution duplication presence / absence monitoring unit 29 that monitors the presence or absence of system execution duplication. The system execution duplication monitoring unit 29 checks whether there is an operation start request of another system, that is, an RF signal transmission request conforming to another system, while performing an RF signal transmission operation as a system execution operation. By monitoring the system execution overlap. That is, the system execution duplication presence / absence monitoring unit 29 of this example detects whether there is an overlap of RF signal transmission requests as duplication of system operation.

  Further, the communication control unit 12 is provided with a system execution order setting unit 30 for setting which system is to be preferentially executed when the execution of system operations overlaps. When the system execution duplication monitoring unit 29 recognizes duplication of system execution, the system execution order setting unit 30 refers to the priority setting table 28 to check which system should be preferentially executed, and sets the priority. The RF signal transmission operation is selectively performed according to the priority order determined from the table 28 to avoid duplication of system operation. Note that the system execution duplication presence / absence monitoring unit 29 and the system execution order setting unit 30 are functionally generated by the CPU 13 and the control program in the memory 14, and in the present example, these are shown in a block diagram. The system execution duplication presence / absence monitoring unit 29 and the system execution order setting unit 30 constitute priority processing means.

  In addition, the electronic key 2 is provided with a notification unit 31 that notifies the user of the operating state of the system priority order processing function. The notification unit 31 includes a display, for example, and the operation is managed by the communication control unit 12. When the system priority order processing function is activated, the notification unit 31 notifies the user of the operation state of the function by displaying the name of the system being executed or displaying the name of the system waiting for the operation execution. . In addition, this alerting | reporting part 31 can display not only the thing according to a system priority order processing function but the various screens related to the electronic key 2. FIG.

  For example, when a button operation is performed on the electronic key 2 or when the electronic key 2 receives a request signal Srq transmitted from the vehicle 1, these button operations and signal reception are requested to transmit an RF signal, that is, a system. The communication control unit 12 accepts the operation start request. And the communication control part 12 produces | generates RF signal according to these operation and states, and this RF signal transmits toward the vehicle 1 from the RF transmitter 16. FIG. For example, when the lock button 18 of the electronic key 2 is operated, the communication control unit 12 generates lock request transmission data, and the data is transmitted from the RF transmitter 16 to the vehicle 1 as the lock request. .

  Here, when the electronic key 2 is transmitting the RF signal, for example, when another button of the electronic key 2 is operated or the electronic key 2 newly receives the request signal Srq, Since the signal transmission requests overlap, the operation of the system executed between the electronic key 2 and the vehicle 1 overlaps. When the system execution duplication monitoring unit 29 confirms the acceptance of a new RF signal transmission request during the transmission of the RF signal, it determines that the system execution operations have overlapped. Then, the system execution order setting unit 30 refers to the priority order setting table 28 and preferentially executes the operation of the system having a high priority determined from the table 28.

  For example, as shown in FIG. 4, when the priority of the system that has newly accepted the operation start request is higher than that of the running system, the running RF signal transmission is forcibly stopped and newly operated. An RF signal corresponding to the button is transmitted to preferentially execute a system that has newly accepted an operation start request. As an example of this operation, for example, when the power slide door opening / closing button 21 is operated while the lock request is transmitted by pressing the lock button 18, the operation for transmitting the lock request is stopped and the power slide is stopped. The opening / closing request is transmitted, and the operation of the power slide door opening / closing system received as a new operation start request is preferentially executed over the wireless door lock system being executed.

  On the other hand, as shown in FIG. 5, when the priority of the running system is higher than that of the system that has newly accepted the operation start request, the running RF signal transmission is continued and the running system is Perform priority. As an example of this operation, for example, even if the lock button 18 is operated while the power slide door open / close request is transmitted by pressing the power slide door open / close button 21, the operation of the lock button 18 at this time is operated. Is ignored, and the operation of transmitting the power slide door opening / closing request is continued, so that the operation of the power sliding door opening / closing system being executed is preferentially executed over the wireless door lock system as a new operation start request.

  At this time, the system execution order setting unit 30 executes the new receiving system after completion of the operation of the running system when preferentially executing the running system over the new receiving system. In this case, when the system execution order setting unit 30 preferentially executes the system being executed, the system execution flag of the system that has newly accepted the operation start request is set in the memory 14, and the operation start request for the new system has been received. Hold. Then, when the transmission operation of the RF signal of the previous system is completed, the system execution order setting unit 30 executes the transmission operation of the RF signal according to the newly accepted system using the execution flag set in the memory 14 as a trigger, Wait for completion of the operation of the system that is executing the operation of the newly accepted system. Note that only one execution flag may be held in the memory 14, or two or more execution flags may be held to store a plurality of button operations.

  Further, the system execution order setting unit 30 forcibly stops the running system and prioritizes the operation of the newly accepted system when the system order of execution overlaps and the priority order of these systems is the same. Execute. In this example, the power slide door opening / closing system and the tailgate opening / closing system have the same priority with high priority.For example, during the execution of the power slide door opening / closing system, the operation start request of the tailgate opening / closing system is received. Upon entering, the operation of the power sliding door opening / closing system is forcibly stopped and the operation of the tailgate opening / closing system is preferentially executed.

  As described above, in this example, the priority setting table 28 in which the priority of system execution is determined is provided in the memory 14 of the communication control unit 12, and the priority determined from the priority setting table 28 when the system execution overlaps. System operations are executed in order. For this reason, for example, once a button is operated, such as a power slide door opening / closing system or tailgate opening / closing system, it is safe to complete the system operation to the end. It becomes possible to finish. Therefore, the electronic key system 3 can be a highly secure and highly functional system.

  Also, when the system operation overlaps, the priority of the system being executed is higher than the system that newly accepted the operation start request, and if this is completed first, the execution flag of the newly accepted system is set. It stands in the memory 14, waits for the completion of the operation of the system being executed, and subsequently executes it. For this reason, when the system operation overlaps, even if the system being executed is preferentially executed, the system received later can be executed without any problem. Therefore, when executing a new reception system having a low priority order, for example, it is not necessary to impose the button operation again on the operator, and this is highly convenient.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) A priority order setting table 28 is prepared in the memory 14 of the electronic key 2. When system operations overlap, a system with a higher priority order determined from the priority order setting table 28 is preferentially executed. Therefore, if the priority of a highly important system that needs to be executed first is set high, the system operations can be executed in the order of considering the importance.

  (2) When the system operation overlaps, if the priority of the newly accepted system is higher, the newly accepted system is preferentially executed, and if the priority of the running system is higher, the system is executing Priority is given to system operation. For this reason, a system with high priority and high importance can always be executed first.

  (3) When preferentially executing a system operation that is being executed due to overlapping system operations, a new acceptance system execution flag is set in the memory 14, and after the system operation being executed is completed, Perform the operation of the receiving system. For this reason, since it is not necessary to impose a redo operation on the newly accepted system on the operator, the convenience of the operation can be improved.

  (4) The priority order setting table 28 sorts the priorities of a plurality of systems by ranking that allows the same order of high, medium and low. For this reason, since it is not necessary to set these priorities in a unique order such as first, second,..., Priority can be set in a flexible format.

  (5) When operations overlap in systems with the same priority, the newly received system operation is preferentially executed, so that items that may become uncertain elements of the operation of overlapping systems with the same priority may be eliminated. it can. Therefore, the system priority order processing function can be made highly reliable.

  (6) Since the system priority order processing function is a key-side management type, a component group related to this function may be included in the electronic key 2. Therefore, when the system priority processing function of this example is installed in the electronic key system 3, it is not necessary to make a special design change to the vehicle 1.

  (7) Since the notification unit 31 is provided in the electronic key 2, the operating state of the system priority order function can be notified to the user. Therefore, the user can sequentially know which system is being executed at that time.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
The priority setting table 28 may be set uniquely such that the execution priority order of each system is first, second,.

  -When a newly accepted system is preferentially executed over a running system, the running system is stopped in the middle, but the operation of the system that was forcibly stopped after completion of the new accepted system is continued. May be continuously executed.

  -The power sliding door opening / closing system is not limited to one that opens and closes with a single opening / closing button, but may have a dedicated operation button for each. This is also true for systems other than the power slide door opening / closing system.

  -When the newly accepted system is executed later, when two or more execution flags can be held, processing may be performed in descending order of priority among the plurality of execution flags.

  In the case where the new reception system is executed later, the transmission of the RF signal in accordance with the new reception system may be performed after completion of the operation of the system previously executed on the vehicle 1 side.

For example, when a plurality of operation start requests (RF signal transmission requests) are received simultaneously (substantially simultaneously), an execution format may be used in which these operations are executed in order of priority.
The system priority order processing function is not limited to the key-side management type that manages the priority order by managing the transmission of the RF signal from the electronic key 2, but this kind of function is provided on the vehicle 1 side, May be managed on the vehicle 1 side (vehicle-side management type). In this case, when a new RF signal is received from the electronic key 2 while the vehicle 1 is executing the system, the vehicle 1 compares the priority order between the system being executed and the system according to the received RF signal. An example of an operation executed first from a system with a high priority is given.

  -If the priority order of the systems that overlap execution is the same, it is not always necessary to preferentially execute the system on the post-operation side. For example, the system of the post-operation is executed after waiting for the completion of the execution of the system being executed. May be.

-The alerting | reporting part 31 is not necessarily limited to a display (monitor), What kind of thing may be employ | adopted if it can notify a user of a state, such as light, a sound, a vibration, for example.
The button of the electronic key 2 is not necessarily provided with a dedicated button for each system, and one button may be shared by a plurality of systems.

  ・ The target system is not limited to the key operation free system, wireless door lock system, power slide door opening / closing system, tailgate opening / closing system, trunk opening / closing system, and window opening / closing system, but only one of these systems may be used. . Further, systems other than these systems may be targeted.

-Needless to say, the electronic key system 3 is not necessarily employed in the vehicle 1 but can be employed in other apparatuses and devices.
