Hereinafter, each example will be described in detail with reference to the accompanying drawings.

FIG. 1 is a system configuration diagram schematically showing an example of the vehicle control device 1. FIG. 2 is a diagram schematically illustrating an example of the vehicle exterior detection area.

The vehicle control apparatus 1 includes a smart entry control ECU (hereinafter simply referred to as “smart ECU”) 10, a body control ECU (hereinafter simply referred to as “body ECU”) 12, an actuator 14, a transmitter 20, and a receiver. 22 and the portable device 30.

The smart ECU 10 may be configured as a microcomputer including a CPU, a ROM, a RAM, and the like connected to each other via a bus (not shown). Various programs executed by the CPU may be stored in the ROM. Note that the function of the smart ECU 10 may be realized by any hardware, software, firmware, and any combination thereof.

The body ECU 12 is connected to the smart ECU 10 via, for example, a bidirectional multiplex communication line. The body ECU 12 may be configured as a microcomputer including a CPU, a ROM, a RAM, and the like connected to each other via a bus (not shown). Various programs executed by the CPU may be stored in the ROM. Various programs executed by the CPU may be stored in the ROM. The function of the body ECU 12 may be realized by any hardware, software, firmware, or any combination thereof. Also, part or all of the functions of the smart ECU 10 may be realized by the body ECU 12 or may be realized by another ECU. Conversely, part or all of the functions of the body ECU 12 may be realized by the smart ECU 10 or may be realized by another ECU.

The body ECU 12 is connected with an actuator (hereinafter referred to as “body actuator”) 14. The body actuator 14 drives the body parts. The body system actuator 14 includes a door lock actuator that drives a door lock mechanism, an actuator that drives the door glass up and down (power window regulator), an actuator that drives the slide door to open and close (motor for power slide door), a back door or a trunk (luggage door). ) May be included (an actuator for power back door or luggage door opener motor), an actuator for opening / closing the sunroof, and the like. The body system actuator 14 is controlled by the body ECU 12.

The smart ECU 10 is connected to a transmitter (transmitter for detection outside the passenger compartment) 20. The transmitter 20 forms a detection area (outdoor detection area) for detecting the portable device 30 outside the passenger compartment. The transmitter 20 includes a vehicle exterior detection antenna, and forms a vehicle exterior detection region by transmitting a request signal (a vehicle exterior detection radio wave) via the vehicle exterior detection antenna. Here, the range in which the request signal transmitted from the vehicle exterior detection antenna can be normally received by the portable device 30 corresponds to the vehicle exterior detection region. A plurality of antennas for detecting outside the vehicle compartment of the transmitter 20 may be set. For example, one for each of the left and right door outside handles corresponding to the driver side door outer space and the passenger side door outer space of the vehicle. It may be built in one by one. In the example illustrated in FIG. 2, the transmitter 20 includes three vehicle

exterior detection antennas

20 a, 20 b, and 20 c corresponding to the driver seat side door external space, the passenger seat side door external space, and the back door external space, respectively. including. In FIG. 2, corresponding to each of the three vehicle

exterior detection antennas

20 a, 20 b, and 20 c, a driver seat side door external space, a passenger seat side door external space, and a back door external space are respectively provided outside the vehicle interior.

Detection areas

80a, 80b, and 80c are formed. The vehicle exterior detection antenna 20c may be incorporated in, for example, a back door handle.

Note that a part of the function of the transmitter 20 (for example, an antenna drive control function) may be realized by the smart ECU 10. For example, the configuration of the transmitter 20 other than the vehicle exterior detection antenna may be incorporated in the smart ECU 10.

The receiver 22 is connected to the smart ECU 10. The receiver 22 receives a response signal or the like from the portable device 30. The receiver 22 is disposed at a position where a response signal transmitted from the portable device 30 can be received. For example, the receiver 22 may be disposed on the side of the rear seat of the vehicle. The receivers 22 may be additionally arranged in the luggage space, and the number and arrangement position thereof are arbitrary. Upon receiving the response signal from the portable device 30, the receiver 22 performs predetermined processing such as amplification and demodulation on the response signal received from the portable device 30, and then supplies the demodulated response signal to the smart ECU 10. To do. The smart ECU 10 compares the ID code included in the received response signal with the ID code stored in a predetermined memory (not shown), and if they match, the smart ECU 10 is a legitimate portable device 30. Authentication result (authentication result to the effect that authentication has been obtained) is output. Note that some of the functions of the receiver 22 may be realized by the smart ECU 10.

The portable device 30 includes a transmitter / receiver (transponder) that performs bidirectional communication with the transmitter 20 and the receiver 22 on the vehicle side using weak radio waves, and a transmission / reception antenna. The portable device 30 includes a storage unit 31 that stores a given valid ID code and a processing device 33 that performs various processes. The portable device 30 includes a button (see FIG. 3) that can be operated by the user, and a function of transmitting a wireless signal instructing door locking / unlocking or the like according to the operation of the button (that is, a normal keyless entry system) May be provided. Moreover, the portable device 30 may be a key with a built-in mechanical key including a mechanical key that can lock and unlock the door of the vehicle by a user operation. Alternatively, the portable device 30 may be a key independent of the mechanical key.

When the portable device 30 receives a request signal (outside vehicle detection radio wave) transmitted via the outside detection antenna of the transmitter 20 as described above, the portable device 30 transmits a response signal corresponding to the request signal. An ID code is incorporated in this response signal. The portable device 30 receives different response signals when receiving a request signal transmitted through the vehicle interior detection antenna and when receiving a request signal transmitted through the vehicle interior key detection antenna. May be configured to transmit. In this case, the smart ECU 10 can grasp whether the portable device 30 exists inside the vehicle compartment or outside the vehicle compartment by decoding the response signal from the portable device 30. Similarly, when the portable device 30 receives a request signal transmitted via one out-of-vehicle detection antenna and when received a request signal transmitted through another out-of-vehicle detection antenna. And may be configured to transmit different response signals. In this case, the smart ECU 10 can grasp in which vehicle exterior detection area the portable device 30 exists by decoding the response signal from the portable device 30.

Next, an example of a basic door lock / unlock operation executed cooperatively by the smart ECU 10 and the body ECU 12 of the present embodiment will be outlined.

<Unlocking the door lock mechanism>
When the parking state of a predetermined vehicle is detected, the smart ECU 10 transmits a request signal via the outside detection antenna of the transmitter 20 so that the outside detection area is formed. For example, as shown in FIG. 2, the outside detection area may be an area indicated by 80 a, 80 b, and 80 c. When the portable device 30 exists in the vehicle exterior detection area, a response signal is received by the receiver 22 from the portable device 30. The smart ECU 10 checks the ID code included in the response signal received by the receiver 22 against the ID code that is set and stored in advance, thereby allowing the portable device 30 having a valid ID code to approach the vehicle. To detect. When the collation of the ID code is confirmed, the body ECU 12 detects a predetermined operation intended by the user to open the door (for example, the door outer handle is provided with contact or proximity of the user's hand to the door outer handle). At the same time, a drive signal for unlocking is supplied to the door lock actuator (an example of the body actuator 14) of the corresponding door lock mechanism. As a result, a door unlocked state is formed, and a user who has a legitimate portable device 30 does not need to take out the portable device 30 and insert it into the key cylinder or operate the UNLOCK button of the portable device 30. You can open the door and get into the car. Hereinafter, the unlocking operation realized using the smart key system in this manner is also referred to as “smart unlocking”. On the other hand, the unlocking operation realized using a normal keyless entry system (unlock command by button operation) is also referred to as “wireless unlock”. Note that unlock operations other than smart unlock and wireless unlock typically include key-linked unlock realized by the user inserting the portable device 30 into the door key cylinder and turning it.

The smart ECU 10 is configured so that, after smart unlock (or wireless unlock), when a door opening / closing operation by the user is detected, a predetermined detection region (vehicle interior detection region) is formed in the vehicle interior. A request signal (vehicle interior detection radio wave) is transmitted via a vehicle interior key detection transmitter and a vehicle interior key detection antenna (not shown). The portable device 30 in the vehicle interior detection area transmits a response signal in response to the request signal, and the response signal is received by the receiver 22. Therefore, when the response signal is received by the receiver 22 and the key authentication is obtained (the ID code matches), the smart ECU 10 determines that the portable device 30 (legitimate user) exists in the vehicle interior. The immobilizer function may be released and the steering lock may be released. In addition, when the smart ECU 10 transmits a request signal (vehicle interior detection radio wave) when operating an engine switch (not shown), and similarly determines that the portable device 30 (authorized user) is present in the vehicle interior, The engine may be allowed to start. Note that the release of the immobilizer function, the unlocking of the steering lock, and the like may be realized directly in conjunction with the courtesy switch being turned on from off without passing through the normal vehicle interior key collation process.

<Locking door lock mechanism>
The smart ECU 10 detects a pressing operation of a lock switch (not shown) disposed on the door outer handle. When the pressing operation of the lock switch is detected, the smart ECU 10 transmits a request signal via the vehicle interior detection antenna of the transmitter 20 so that the vehicle exterior detection region is formed. The vehicle exterior detection area may be an area indicated by 80a, 80b, 80c as shown in FIG. 2, for example. When the portable device 30 exists in the vehicle exterior detection area, a response signal is received by the receiver 22 from the portable device 30. The smart ECU 10 collates the ID code included in the response signal received by the receiver 22 with the ID code that is set and stored in advance, so that the portable device 30 having a valid ID code is taken out of the vehicle. To detect. When the collation of the ID code is confirmed, the body ECU 12 supplies a drive signal for locking to the door lock actuator of the unlocked door lock mechanism. As a result, a door lock state is formed, and a user who has a legitimate portable device 30 locks the door without taking out the portable device 30 and inserting it into the key cylinder or operating the LOCK button of the portable device 30. can do. Here, the request signal is transmitted when the pressing operation of the lock switch is detected, but the request signal may be transmitted when the opening / closing of the door is detected after the engine is stopped. In this case, the door can be locked without requiring a pressing operation of the lock switch.

Next, the reservation function of the portable device 30 will be described.

The portable device 30 has a reservation function that can reserve the operation of the body actuator 14. The body system actuator 14 to be reserved may be arbitrarily determined. For example, the body system actuator 14 to be reserved is one of a door lock actuator operation, a power window regulator, a power sliding door motor, an actuator that opens and closes a back door or a trunk, and an actuator that opens and closes a sunroof. Or any combination of two or more. It should be noted that the body actuator 14 to be reserved is typically actuated by transmitting a wireless signal that can be instructed to operate by a button operation on the portable device 30 (that is, a wireless signal is transmitted). Body actuator 14).

The reservation method of the operation of the body-type actuator 14 for the portable device 30 may be to perform a predetermined reservation input (reservation input from the outside) to the portable device 30. The predetermined reservation input is arbitrary including button input and voice input. The predetermined reservation input is typically an input by a predetermined reservation operation in the operation unit of the portable device 30. When a plurality of operations of the body actuator 14 can be reserved, the predetermined reservation input may include input information for specifying which operation is reserved. When a predetermined reservation is input, the portable device 30 stores (holds) information (reservation information) indicating that in the storage unit 31. The reservation information may be in the form of a flag, for example. When the number of body-type actuators 14 that can be reserved is plural, the reservation information may include information indicating which body-type actuator 14 is reserved for operation (that is, information indicating a reservation operation).

The portable device 30 preferably outputs information indicating that (reservation acceptance completion information) to the outside when holding the reservation information (that is, in response to a predetermined reservation input). This output method is arbitrary including sound (including a message) or vibration generated from the portable device 30. Thereby, the user can confirm that the reservation operation is completed.

The reservation information held in the portable device 30 may be cancelable (can be deleted) by a predetermined cancel input. This is because the user may make a reservation once, but may want to reconsider and cancel the reservation later. The predetermined cancel input is arbitrary including button input and voice input. The predetermined cancel input is typically an input by a predetermined cancel operation in the operation unit of the portable device 30. In this case, when the portable device 30 receives a predetermined cancel input, the portable device 30 deletes the reservation information in the storage unit 31. Note that the portable device 30 may also output information indicating that (reservation erasure completion information) to the outside even when erasing the reservation information in response to a predetermined cancel input.

In addition, the reservation information held in the portable device 30 may be deleted after a predetermined reservation holding time T1 has elapsed from the time when a predetermined reservation is input. This is because when a very long time has passed after the reservation, there is a high possibility that the reservation is no longer necessary. However, depending on the user, there is a possibility of making a reservation for a considerable time before, so the predetermined reservation holding time T1 may be set to a relatively long time (for example, 24 hours). The predetermined reservation holding time T1 may be selectable by the user.

When the portable device 30 holds the reservation information, it receives the request signal from the vehicle side and transmits the reservation signal. The form of the reservation signal may be arbitrary. For example, the reservation signal may be the same as the wireless signal transmitted by the button operation of the portable device 30, or the reservation signal may be included in a response signal transmitted with respect to the request signal.

When the portable device 30 transmits the reservation signal, the reservation information in the storage unit 31 may be deleted. This is because the reservation operation is realized when the reservation signal is transmitted (that is, the current reservation ends its role). However, the portable device 30 deletes the reservation information in the storage unit 31 only when a predetermined execution completion signal (for example, a signal notifying that the reservation operation has been realized) is received from the vehicle side in response to the reservation signal. It is good to do. In this case, the portable device 30 may continue to transmit the reservation signal at every predetermined period until the execution completion signal is received (provided that the portable device 30 is located in the vehicle exterior detection area). Condition). In the configuration in which the execution completion signal is not transmitted from the vehicle side, the portable device 30 may transmit the reservation signal and delete the reservation information in the storage unit 31.

FIG. 3 is a diagram illustrating an example of an operation unit in the portable device 30, and is a diagram illustrating examples of operation buttons in the two

portable devices

30A and 30B. Note that the button configurations shown in FIGS. 3A and 3B are merely examples, and may be appropriately changed according to the function of the vehicle (such as the presence or absence of a power door).

In the example shown in FIG. 3A, the portable device 30A includes a LOCK button 34, an UNLOCK button 36, a PSD (L) button 37a, a PSD (R) button 37b, a PBD button 37c, and a reservation button 38. The portable device 30A includes an indicator 32. The indicator 32 may include an arbitrary light source such as an LED (Light-Emitting / Diode).

The LOCK button 34 and the UNLOCK button 36 are buttons that are operated when the door is locked and unlocked, respectively. For example, when the LOCK button 34 is pressed, the portable device 30A transmits a wireless signal instructing a door lock. When this wireless signal is received by the receiver 22, the body ECU 12 drives the door lock actuator to realize the door lock.

The PSD (L) button 37a and the PSD (R) button 37b are buttons that are operated when the left and right sliding doors are automatically opened and closed. For example, when the PSD (L) button 37a is pressed, the portable device 30A transmits a wireless signal instructing opening / closing of the left slide door. When this wireless signal is received by the receiver 22, the body ECU 12 drives the power sliding door motor to open and close the left sliding door.

The PBD button 37c is a button operated when the back door is automatically opened and closed. For example, when the PBD button 37c is pressed, the portable device 30A transmits a wireless signal instructing opening / closing of the back door. When this wireless signal is received by the receiver 22, the body ECU 12 drives the power back door motor to open and close the back door.

The reservation button 38 is a button operated when reserving the operation of the body actuator 14 to be reserved. In the example shown in FIG. 3A, it is assumed that the body system actuator 14 to be reserved is a power slide door motor and a power back door motor. In this case, the reservation operation for opening and closing the left sliding door may be, for example, pressing the PSD (L) button 37 a after pressing the reservation button 38. Similarly, the reservation operation for opening and closing the right sliding door may be, for example, pressing the PSD (R) button 37 b after pressing the reservation button 38. Similarly, the reservation operation for opening and closing the back door may be, for example, pressing the PBD button 37c after pressing the reservation button 38. As described above, the reservation operation may be different for each reservation operation. However, as will be described later, the reservation operation can be the same for each reservation operation.

3B, the portable device 30B includes a LOCK button 34, an UNLOCK button 36, a TRUNK button 37, and a reservation button 38. The portable device 30B includes an indicator 32.

In the example shown in FIG. 3B, the body-type actuator 14 to be reserved may be an actuator that opens and closes the trunk. In this case, the reservation operation for opening and closing the trunk may be, for example, pressing the TRUNK button 37 after pressing the reservation button 38. Note that, as in the example shown in FIG. 3B, when only one body system actuator 14 is to be reserved, the operation of the TRUNK button 37 after pressing the reservation button 38 is unnecessary. Good. That is, the reservation operation for opening and closing the trunk may be performed simply by pressing the reservation button 38.

3A and 3B, the portable device 30A and the portable device 30B may perform a reservation acceptance completion display when a reservation operation is performed. The reservation acceptance completion display may be realized by turning on the indicator 32. The indicator 32 may be turned on for a predetermined time or may be realized in a predetermined pattern including blinking. In this case, since the existing indicator 32 can be used, the user can be notified that the reservation has been registered without any additional configuration.

In the example shown in FIGS. 3A and 3B, the portable device 30A and the portable device 30B may delete the reservation information currently held when a predetermined reservation cancel operation is performed (ie, You may cancel the reservation). The predetermined reservation canceling operation is arbitrary, but may be a long press of the reservation button 38 for a predetermined second or longer. Note that the portable device 30A and the portable device 30B may perform a reservation erasure completion display when a reservation cancel operation is performed. The reservation erasure completion display may be realized by turning on the indicator 32. The reservation erasure completion display may be the same as or different from the reservation acceptance completion display. In this case, since the existing indicator 32 can be used, the user can be notified that the reservation has been canceled without any additional configuration.

FIG. 4 is a flowchart showing an example of processing executed by the portable device 30 for reservation outside the vehicle compartment. Note that the processing shown in FIG. 4 may be realized by the processing device 33 inside the portable device 30. Note that the processing device 33 inside the portable device 30 may be configured by an arithmetic processing device including a CPU. Various functions (including functions described below) of the processing device 33 of the portable device 30 may be realized by arbitrary hardware, software, firmware, or a combination thereof. Hereinafter, as an example, the portable device 30A illustrated in FIG. 3A is assumed as the portable device 30.

In step 400, a reservation operation in the portable device 30 is detected. The reservation operation may be arbitrary as described above. For example, in the example shown in FIG. 3A, the operation of the reservation button 38 and the subsequent PSD (L) button 37a, PSD (R) button 37b, and PBD button. 37c may be any combination of operations. If a reservation operation is detected, the process proceeds to step 405. When a reservation operation is detected, reservation information is stored in the storage unit 31 of the portable device 30 as described above.

In step 405, it is determined whether or not a request signal (outside vehicle detection radio wave) transmitted via the outside vehicle detection antenna of the transmitter 20 has been received. At this time, the ID code that may be included in the request signal and the ID code in the storage unit 31 of the portable device 30 may be collated to determine whether or not the request signal is for itself. If a request signal has been received, the process proceeds to step 406. On the other hand, when a request signal is not received, it enters a reception waiting state. Accordingly, when a reservation operation is performed, the portable device 30 enters a request signal reception waiting state, and when a request signal is received, the process proceeds to step 406.

In step 406, the portable device 30 transmits a reservation signal. This reservation signal is a signal for realizing the operation of the body actuator 14 related to the reservation. The form of the reservation signal may be arbitrary.

For example, the reservation signal may be the same as the wireless signal transmitted by the button operation of the portable device 30. For example, the reservation signal related to the reservation operation for opening and closing the left sliding door may be the same as the wireless signal transmitted when the PSD (L) button 37a of the portable device 30 is pressed. In this case, the wireless signal is transmitted separately from the response signal transmitted in response to the request signal received in step 405. In this case, it is not necessary to substantially change the specifications of the vehicle side devices (such as the smart ECU 10 and the body ECU 12) due to the addition of the reservation function. That is, the body ECU 12 may realize the operation of the body system actuator 14 according to the received wireless signal. However, at this time, the operation of the body system actuator 14 may be realized only when authentication based on the ID code included in the response signal received separately from the wireless signal is obtained.

Alternatively, the reservation signal may be included in the response signal transmitted in response to the request signal received in step 405. That is, the response signal includes an ID code as described above, but a reservation code representing the reservation signal is incorporated in addition to the ID code. In this case, the receiver 22 decodes the reservation code, and the body ECU 12 realizes the operation of the body system actuator 14 according to the reservation code. At this time, the operation of the body actuator 14 may be realized only when authentication based on the ID code included in the response signal is obtained.

According to the process shown in FIG. 4, when a reservation operation is performed in the portable device 30, a reservation signal is transmitted when the user who owns the portable device 30 approaches the vehicle, and the reservation operation is realized. For example, when a reservation operation for opening and closing the left sliding door is performed, when the user holding the portable device 30 approaches the vehicle (that is, when the portable device 30 enters the outside detection area). A reservation signal is transmitted. In response to the reservation signal, the body ECU 12 drives the door lock actuator to unlock the left slide door and drives the power slide door motor to open the left slide door. Therefore, the user does not have to bother to put the baggage and press the PSD (L) button 37a in a state where both hands are occupied with the baggage, for example, and the convenience is improved. Thus, for example, when it is predicted that both hands will be blocked by baggage, etc. when boarding, the user does not need to operate the operation unit of the portable device 30 only after performing a reservation operation in advance, The opening of the slide door or the like can be realized only by approaching the vehicle (just by the portable device 30 entering the outside detection area).

Further, according to the process shown in FIG. 4, the driving of the body actuator 14 related to the reservation is performed when the user holding the portable device 30 approaches the vehicle regardless of the timing when the reservation operation is performed (that is, the portable device 14 is carried). This is realized when the machine 30 enters the outside detection area. Therefore, the user does not need to worry about the timing for performing the reservation operation, and does not need to set a reservation time or the like. Thus, according to the present embodiment, the convenience is improved as compared with the configuration in which the reservation signal is transmitted after a predetermined time from the reservation operation time point.

In the example shown in FIG. 4, the reservation signal transmitted in step 506 is a signal for realizing the operation of the body system actuator 14 related to the reservation. Therefore, when there are a plurality of operations that can be reserved, the reservation signal to be transmitted is a different signal depending on the reservation operation. For example, the reservation signal to be transmitted is naturally different when the reservation operation for opening and closing the left slide door is performed and when the reservation operation for opening and closing the right slide door is performed. Further, a plurality of operations may be reserved at the same time. In this case, a plurality of reservation signals may be transmitted.

In the example shown in FIG. 4, the reservation signal is transmitted in response to the first request signal from the vehicle side, but instead of or in addition, in response to reception of the second and subsequent request signals. May be sent.

In addition, when the request signal transmitted via the outside detection antenna of the transmitter 20 is different for each outside detection antenna (for example, there is a difference in codes included), the reservation signal to be transmitted is the request signal. It may be different depending on. For example, in the example shown in FIG. 2, when a request signal is received from the vehicle exterior detection antenna 20 a, the reservation signal that is transmitted may be a signal that commands the operation of an actuator that opens and closes the right sliding door. . Further, when a request signal is received from the vehicle exterior detection antenna 20b, the transmitted reservation signal may be a signal for instructing an operation of an actuator that opens and closes the left sliding door. Further, when a request signal is received from the vehicle exterior detection antenna 20c, the reservation signal to be transmitted may be a signal for instructing an operation of an actuator that opens and closes the back door. In such a configuration, the user does not need to specify which body system actuator 14 is to be reserved at the time of the reservation operation (that is, only the reservation button 38 needs to be pressed). In this case, the user who performed the reservation operation can realize opening of the door and the like only by approaching the desired door.

In addition, when it is possible to determine in which detection area outside the passenger compartment the portable device 30 is located on the vehicle side, the reservation signal transmitted in step 506 is a signal for commanding the operation of the body system actuator 14 related to the reservation. Instead, it may be a signal simply indicating reservation (that is, a signal that does not specify which body actuator 14 should be operated). It should be noted that it may be determined based on the position of the receiving antenna that received the response signal or the response signal itself, in which vehicle compartment detection area the portable device 30 is located. For example, in the example shown in FIG. 2, when the portable device 30 is located in the vehicle exterior detection area 80a, the body ECU 12 realizes the operation of the actuator that opens and closes the right sliding door in response to the reservation signal. Also good. Further, when the portable device 30 is located in the outside detection area 80b, the body ECU 12 may realize an operation of an actuator that opens and closes the left sliding door in response to the reservation signal. Further, when the portable device 30 is located in the outside detection area 80c, the body ECU 12 may realize the operation of the actuator that opens and closes the back door in response to the reservation signal. In such a configuration, the user does not need to specify which body system actuator 14 is to be reserved at the time of the reservation operation (that is, only the reservation button 38 needs to be pressed). In this case, the user who performed the reservation operation can realize opening of the door and the like only by approaching the desired door.

FIG. 5 is a flowchart showing another example of processing executed by the portable device 30 for reservation outside the passenger compartment. Note that the processing shown in FIG. 5 may be realized by the processing device 33 inside the portable device 30 as in the processing shown in FIG. The process shown in FIG. 5 is mainly different from the process shown in FIG. 4 in that steps 502, 503, 504, 507, and 508 are added. That is, the processing in steps 501, 505, and 506 may be the same as the processing in steps 401, 405, and 406 shown in FIG. Therefore, only different parts will be described below.

In step 502 subsequent to step 501, the reservation acceptance completion display is performed with the storage of the reservation information, and the timer T starts counting up.

In step 503, it is determined whether or not the timer T (count value) is less than the reservation holding time T1. If the timer T is less than the reservation holding time T1, the process proceeds to step 504. Otherwise (ie, the timer T reaches the reservation holding time T1), the process proceeds to step 507.

In step 504, it is determined whether or not a reservation cancel operation has been performed. As described above, the reservation canceling operation may be a long press of the reservation button 38 for a predetermined second or more. If there is a reservation cancel operation, the process proceeds to step 507. Otherwise, the process proceeds to step 505.

In step 507, the reservation is canceled. That is, the reservation information stored in the storage unit 31 is deleted. When the process of step 507 is completed, the process proceeds to step 508. Note that the process also proceeds to step 508 when the process of step 506 is completed.

In step 508, the count value of timer T is cleared.

According to the process shown in FIG. 5, the same effect as the process shown in FIG. 4 can be obtained. Further, according to the process shown in FIG. 5, it is possible to visually confirm the completion of the reservation operation (step 502), the reservation can be canceled (step 504), and the reservation information after the reservation holding time T1 has elapsed. Can be automatically erased (steps 503 and 507).

FIG. 6 is a flowchart illustrating an example of processing that may be executed during a reservation operation in the portable device 30. 6 may be realized by the processing device 33 inside the portable device 30. The processing routine shown in FIG. 6 may be executed as the processing of step 401 in FIG. 4 or step 501 in FIG. The processing routine shown in FIG. 6 is executed for a configuration in which the reservation operation is a combined operation of the operation of the reservation button 38 and the operation of other buttons. For example, in this configuration, for example, as described above with reference to FIG. 3A, the reservation operation for opening and closing the left sliding door is performed by pressing the PSD (L) button 37a after pressing the reservation button 38. The configuration in which the reservation operation for opening and closing the right slide door is to press the PSD (R) button 37b after pressing the reservation button 38, and the reservation operation to open and close the back door is the reservation button 38. After pressing, the PBD button 37c is pressed.

In step 601, it is determined whether or not the reservation button 38 (see FIG. 3A) has been operated. If the reservation button 38 is operated, the process proceeds to step 602.

In step 602, transmission of a wireless signal in response to an operation of another button on the portable device 30 is prohibited. Therefore, in this prohibited state, for example, in the example shown in FIG. 3A, even if the PSD (R) button 37b is pressed after the reservation button 38 is pressed, the PSD (R) button 37b The wireless signal that should be transmitted in response to the operation is not transmitted.

In step 603, it is determined whether or not a certain time has elapsed since the prohibition state was formed. The certain time may correspond to the maximum value that can be taken by a series of reservation operations. If a certain time has elapsed since the prohibition state was formed, the process proceeds to step 605, and otherwise, the process proceeds to step 604.

In step 604, it is determined whether or not the reservation operation is completed. When the reservation operation is completed, the process proceeds to step 605, and otherwise, the process returns to step 602 (in this case, the wireless signal transmission prohibited state from the portable device 30 continues).

In step 605, the prohibition state (inhibition state of wireless signal transmission from portable device 30) formed in step 602 is canceled. Therefore, thereafter, unless the reservation button 38 is operated again, a wireless signal is transmitted according to the operation of each button in the portable device 30.

According to the processing shown in FIG. 6, when a user performs a reservation operation within a reachable range of the wireless signal (for example, in the vicinity of a parked vehicle), a wireless signal is transmitted due to a button operation necessary for the reservation operation. Thus, it is possible to prevent the sliding door from being opened unintentionally. Therefore, according to the process shown in FIG. 6, various reservation operations can be performed in such a manner that the unintended operation of the body actuator 14 is prevented without unnecessarily increasing the number of buttons provided on the portable device 30. .

In the process shown in FIG. 6, the buttons that are prohibited from transmission of wireless signals may be limited to only the buttons used for the reservation operation. For example, in the example shown in FIG. 3A, when the body system actuator 14 to be reserved is only a power slide door motor and a power back door motor, it responds to the operation of the LOCK button 34 or the UNLOCK button 36. The transmission of the wireless signal may not be prohibited immediately after the reservation button 38 is operated.

Next, the reservation in the passenger compartment will be explained. Note that the control related to the reservation in the passenger compartment described below may be realized in combination with the control related to the reservation outside the passenger compartment described above, or only one of them may be realized. In the case of reservation in the passenger compartment, the user typically performs a reservation operation in the passenger compartment before getting out of the vehicle. The control related to the reservation in the passenger compartment may be executed for the reservation in the passenger compartment made while the ignition switch is on and / or for the reservation in the passenger compartment made after the ignition switch is turned off. The reservation operation method may be the same as described above. When a reservation operation is performed in the passenger compartment, the portable device 30 may hold the reservation information in the same manner as described above, but does not hold the reservation information (or only holds it temporarily), It may be sent immediately. In this case, the reservation signal may be a signal indicating that a reservation has been made (however, information for specifying a reservation operation may be included) instead of the kind of reservation signal substituted for the above-described wireless signal. In the case where the control relating to the reservation in the passenger compartment is combined with the control relating to the reservation outside the passenger compartment described above, whether or not a reservation operation has been performed in the passenger compartment is determined by whether the received request signal is for detecting the passenger compartment. It may be determined based on whether the vehicle is used for detection outside the vehicle compartment. This is because when a reservation operation is performed in the vehicle interior, the vehicle interior detection signal (request signal) is received first, and when a reservation operation is performed outside the vehicle interior, the vehicle exterior detection signal (request signal) is received. ) Is received first.

FIG. 7 is a flowchart showing an example of processing executed by the smart ECU 10 in connection with reservation in the vehicle interior. Here, it is assumed that the reservation operation related to the reservation in the passenger compartment is, for example, the closing operation of the right slide door.

In step 700, it is determined whether or not a reservation operation has been performed in the portable device 30 in the passenger compartment. In addition, regarding the reservation in the passenger compartment, the reservation operation may be realized not by the portable device 30 but by an operation (or voice input) with respect to the operation unit in the passenger compartment. The operation unit in the vehicle compartment may include, for example, an operation switch disposed on a touch panel, an instrument panel, or the like. In the configuration in which the reservation operation is performed in the portable device 30, the smart ECU 10 receives the reservation signal from the portable device 30, for example, after the ignition switch is turned off, the vehicle interior key detection transmitter and the vehicle interior key detection. The request signal (vehicle interior detection radio wave) may be transmitted via the antenna. In this case, if the reservation signal is included in the response signal from the portable device 30 in response to the request signal, it is determined that there is a reservation operation in the vehicle interior, and the response signal from the portable device 30 in response to the request signal is When the reservation signal is not included, it may be determined that there is no reservation operation in the passenger compartment. If there is a reservation operation in the passenger compartment, the process proceeds to step 702, and otherwise, the process ends.

In step 702, for example, based on information from the door courtesy switch, it is determined whether or not the right slide door is open. If the right slide door is in the open state, the process proceeds to step 704. Otherwise, the process waits for the right slide door to be opened.

In step 704, a request signal is transmitted from the vehicle exterior detection transmitter and / or vehicle interior detection transmitter. In this case, the request signal may be transmitted only from the vehicle interior key detection transmitter and the vehicle interior key detection antenna, or from only the vehicle exterior key detection transmitter and the vehicle exterior key detection antenna (transmitter 20). A request signal may be transmitted, or a request signal may be transmitted from both sides. When request signals are transmitted from both sides, first, a request signal is transmitted only from the vehicle interior key detection transmitter and vehicle interior key detection antenna, and when the response signal is interrupted, the vehicle exterior key detection transmitter and vehicle exterior key are transmitted. The request signal may be transmitted only from the detection antenna (transmitter 20).

In Step 706, it is determined whether or not the receiver 22 has received a response signal from the portable device 30 that responds to the request signal transmitted in Step 704. When the portable device 30 is located within the detection area of the vehicle exterior detection transmitter and / or the vehicle interior detection transmitter, a response signal from the portable device 30 is received. When the response signal from the portable device 30 is received, the process returns to step 704, and when the response signal from the portable device 30 is not received, the process proceeds to step 708. In this way, when the right sliding door is opened, the process of step 704 is repeated until reception of the response signal from the portable device 30 is interrupted.

Note that the determination method in step 706 differs depending on how the request signal is transmitted in step 704. For example, in step 704, first, a request signal is transmitted only from the vehicle interior key detection transmitter and the vehicle interior key detection antenna, and when the response signal is interrupted, the vehicle exterior key detection transmitter and the vehicle interior key detection antenna. When the request signal is transmitted only from (transmitter 20), the determination in step 706 is that the response signal to the request signal from the vehicle interior key detection transmitter and the vehicle interior key detection antenna is not received by the receiver 22. After that, it is determined whether or not a response signal to the request signal from the transmitter 20 has been received by the receiver 22.

In step 708, the reservation operation is realized. Specifically, the body system actuator 14 is operated via the body ECU 12 to realize the closing operation and the locking operation of the right slide door. The locking operation may be performed on all doors simultaneously.

Note that the realization timing of the reservation operation in step 708 differs depending on how the request signal is transmitted in step 704. Specifically, in the configuration in which the request signal is transmitted only from the vehicle interior key detection transmitter and the vehicle interior key detection antenna in step 704, the reservation operation is realized at the timing when the portable device 30 comes out of the vehicle interior detection area. Is done. On the other hand, in the configuration in which the request signal is transmitted only from the vehicle key detection transmitter and the vehicle key detection antenna (transmitter 20) or the request signal is transmitted from both, the portable device is outside the vehicle detection region. The reservation operation is realized at the timing when 30 is issued.

According to the process shown in FIG. 7, when a reservation operation is performed in the vehicle interior, the user carrying the portable device 30 goes out of the detection area (the vehicle interior detection area or the vehicle exterior detection area). In addition, the reservation operation is realized. For example, when a reservation operation for closing the right sliding door is performed, the closing operation of the right sliding door is realized when the user holding the portable device 30 goes out of the detection area. That is, the smart ECU 10 drives the power slide door motor via the body ECU 12 to close the right slide door, and drives the door lock actuator to lock all the doors. Accordingly, the user does not have to bother to put the baggage and press the PSD (R) button 37a in a state where both hands are occupied with the baggage, for example, and the convenience is improved. Thus, for example, when it is predicted that both hands will be blocked by baggage when getting off the vehicle, the user only needs to perform a reservation operation in the passenger compartment in advance and then operate the operation unit of the portable device 30. However, only by moving away from the vehicle (the portable device 30 possessed by the user moves out of the detection area), the closing operation of the slide door or the like can be realized.

The process shown in FIG. 7 relates to the closing operation of the slide door, but the same may be applied to the closing operation of other doors. The same applies to the closing operation of the door glass. However, in the case of the door glass closing operation, after the door opening / closing is detected, when the portable device 30 having a valid ID code goes out of the vehicle exterior detection area, or the portable device 30 having a valid ID code. When the taking-out of the vehicle outside is detected, the door glass closing operation may be realized. In this case, the portable device 30 may transmit the reservation signal in a manner that responds to the request signal, or may transmit the reservation signal when a reservation operation is performed.

As mentioned above, although each Example was explained in full detail, it is not limited to a specific Example, A various deformation | transformation and change are possible within the range described in the claim. It is also possible to combine all or a plurality of the components of the above-described embodiments.

For example, in the above-described embodiment, the actuator to be reserved is the body actuator 14 arranged on the door of the vehicle (particularly, the body actuator 14 capable of instructing the operation by the button operation on the portable device 30). However, the reservation target actuator may be an arbitrary actuator mounted on the vehicle. For example, the reservation target actuator may be an actuator that changes the seat position or height. In this case, the reservation operation may be an operation in which the seat is lowered to the rearmost position so that the boarding / exiting property is good. The reservation target actuator may be an actuator (for example, a compressor or a blower motor) that drives the air conditioner. In this case, the reservation operation may be an operation for realizing heating or cooling according to the environmental temperature (for example, detected by an outside air temperature sensor or the like). Further, the reservation target actuator may be a heater embedded in a steering wheel or a seat. In this case, the reservation operation may be an operation for heating the steering wheel or the seat. In addition, the reservation target actuator may be a heater (heat wire) for preventing the glass from fogging or freezing. The operation of the actuators to be reserved may be instructed by button operation on the portable device 30 (operation by a wireless signal) or may not be possible. For example, it may be possible to instruct the operation of these actuators by providing a multifunction button on the portable device 30.
