Description

  The present invention relates to a vehicular information output control device that outputs preset message information into a passenger compartment when a driver or the like gets into a vehicle.

  2. Description of the Related Art Conventionally, a personal computer is known that enhances the value of a product by expressing a welcome message such as “welcome” or “welcome” to the user with video and sound when the start switch is turned on.

On the other hand, various techniques for outputting a welcome message to an occupant at the time of boarding have been proposed. For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2005-346264), when a driver or the like opens a door, the audio system power is turned on, then the door is closed, and when the driver's boarding is detected, A technique is disclosed in which a welcome message is output from a system to an occupant.
JP 2005-346264 A

  However, in the technology disclosed in Patent Document 1, since the audio system power is turned on when the door is opened and the standby state is entered, the audio system is still started up when the passenger gets on the vehicle immediately after the door is opened. There is a case where the boarding is completed in a situation where there is not. In such a situation, for example, even if the driver's boarding is detected by the seating sensor, the audio system is not started up, so that the welcome message is not output and the driver's expectation is impaired.

  In view of the above circumstances, the present invention is for a vehicle that can output message information reliably and satisfy the driver's expectation sufficiently even when the user opens the door and rides quickly. An object is to provide an information output control device.

To achieve the above object, the present invention is provided in a portable device used for locking and unlocking a door lock of a vehicle, a communication unit provided in the vehicle and performing wireless communication with the portable device, and the vehicle. In a vehicle information output control device comprising an in-vehicle information input / output unit for outputting message information stored in advance to an occupant, the in-vehicle information input is detected when the unlocking operation of the door lock by the portable device is detected. After the power of the output unit is turned on, a control means is provided for outputting the message information to the occupant when a predetermined condition is satisfied, and the control means until the preset time elapses after the engine is stopped. The output of the message information from the in-vehicle information input / output unit is restricted .

  According to the present invention, when the door lock is unlocked using the portable device, the vehicle information input / output unit is turned on. Sufficient time can be secured between opening and boarding, and even when the user quickly opens the door and gets on, for example, when the door is closed, the message information is immediately output. And the user's expectation can be fully satisfied.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a control unit of a door locking / unlocking unit and a control unit of an in-vehicle information input / output unit mounted on a vehicle using an in-vehicle communication line, and FIG. 2 is an overall configuration diagram of the in-vehicle information input / output unit. is there. Note that the information input / output unit 1 as the in-vehicle information input / output unit shown in FIG. 2 uses functions provided in the car audio device in the present embodiment.

  The door locking / unlocking unit 21 includes a transmission / reception unit 22, a control unit 23, and an actuator driving circuit 24 that outputs a driving signal for locking and unlocking the door. The transmission / reception unit 22 includes an outdoor antenna 22a and an indoor antenna 22b, and a user's boarding is detected by receiving a signal from a portable device 31 (to be described later) by the indoor antenna 22b. Reference numeral 31 denotes a portable device that transmits and receives an ID signal to and from the door locking / unlocking unit 21.

  The transmission / reception unit 22 includes a communication unit (not shown) for performing two-way wireless communication with the portable device 31. The communication unit transmits an ID request signal for prompting the portable device 31 to transmit an ID signal from the outdoor antenna 22a to the outside of the vehicle, and a signal (ACK signal, ID) transmitted from the portable device 31. Code). The control unit 23 is a microcomputer including a CPU, a ROM, a RAM, and the like, and various programs executed by the CPU, ID codes, and the like are stored in the ROM. The CPU controls a communication unit provided in the transmission / reception unit 22 according to a program stored in the ROM, realizes bidirectional communication with the portable device 31, and also uses a door lock actuator 25 via the actuator drive circuit 24. On the other hand, a locking signal or an unlocking signal is output to lock and unlock the door lock.

  On the other hand, the portable device 31 receives an ID request signal transmitted from the communication unit provided in the door locking / unlocking unit 21, and also transmits an ACK signal (acknowledgment signal) to the activation request signal to the communication unit, It has a function as a so-called smart key including a transmission / reception unit 32 that wirelessly transmits an ID code unique to the portable device 31 and a control unit 33 that stores an ID code unique to the portable device 31.

  When the control unit 33 of the portable device 31 receives the ID request signal transmitted from the communication unit provided in the door locking / unlocking unit 21 via the transmission / reception unit 32, the control unit 33 transmits the ID code via the transmission / reception unit 32. To do.

  When the user carrying the portable device 31 enters the communication area of the communication unit provided in the door locking / unlocking unit 21, the transmission / reception unit 32 of the portable device 31 is changed from the communication unit provided in the transmission / reception unit 22. The response signal including the unique ID code is transmitted from the transmission / reception unit 32 to the communication unit.

  Then, the control unit 23 of the door locking / unlocking unit 21 collates the ID code included in the response signal received by the communication unit with the code recorded in its own memory, and whether the portable device 31 is for the vehicle. If the portable device 31 is for the vehicle, an unlock signal is output to the actuator drive circuit 24, and the door lock actuator 25 is unlocked to unlock the door. Further, when the user moves away from the vehicle and the portable device 31 carried away from the communication area of the communication unit, the response signal is not received, and the control unit 33 outputs a locking signal to the actuator drive circuit 24 and the door lock. The door 25 is automatically locked by operating the actuator 25 to lock.

  The unlock signal output from the control unit 33 of the door locking / unlocking unit 21 is transmitted to the control unit (ECU) 2 as the control means of the information input / output unit 1 through the in-vehicle communication line 40. The unlocking signal is activated as a trigger.

  The control unit 2 has a function of performing audio control such as output of message information to a passenger, and is a microcomputer including a CPU, a ROM, a RAM, and the like. Etc. are stored. The control unit 2 is connected with a door switch 3, a recording switch 4, an ignition switch 5, and an operation start operation detection unit 6 as a door opening / closing detection means, an audio operation unit 7, and a DSP (Digital Signal Processor) circuit. 8 is connected.

  The operation start operation is a series of operations performed when the user tries to start traveling, and is a general term for each operation start state that can be detected by the sensor switch. When any of the switches is detected, it is determined that the operation is a start operation. The sensor / switch that detects the start operation is a key insertion detection switch that turns on when the key is inserted into the key groove, an accessory switch that turns on when the key inserted into the key groove is set at the accessory (ACC) position, and a parking lever. There are a parking brake switch that is turned OFF when is opened, a select position switch that detects the position of the select lever, a vehicle speed sensor that detects the vehicle speed, and the like.

  The operation start operation detection unit 6 is configured by selecting one or more of these sensors and switches. For example, when a select position switch and a parking brake switch are selected as the operation start operation detection unit 6, the select position switch detects a state in which the select lever is moved from the P range to another range, or a parking brake switch. When is turned off, it is determined that there is a driving start operation. In this case, if the audio switch provided in the audio operation unit 7 is turned on before detecting the start of operation in the key operation, this may be determined as the operation start operation.

  Further, a CD player 9, an audio amplifier 10, an A / D converter 11 and the like are connected to the DSP circuit 8. Furthermore, a speaker 12 as output means is connected to the audio amplifier 10, and a microphone 13 is connected to the A / D converter 11. The door switch 3 is turned on when the door is opened and turned off when the door is closed. Although the door switch 3 according to the present embodiment is intended for a driver seat side, all the door switches of the vehicle may be connected to the control unit 2 via an OR circuit. The CD player 9 has a built-in memory 9a, and message information is stored in the memory 9a. This message information includes a standard message and a personal message. The standard message stores a plurality of information such as music and voice representing hospitality when boarding, and the personal message includes music dubbed by the user from the CD player 9 and voice input through the microphone 13. It can be memorized.

  The personal message is stored by operating the recording switch 4. The recording switch 4 is a push switch. Recording of a personal message is started by pressing the recording switch 4 once, and recording is stopped by pressing again. At the time of recording, music output from the CD player 9 is recorded when the CD player 9 is driven, and sound input from the microphone 13 is recorded when the CD player 9 is stopped.

  The audio operation unit 7 is configured by a collection of an ON / OFF switch, a music selection button, a volume knob, a preset switch, and the like of the CD player 9. The preset switch is used to select one message information from a plurality of message information stored in the memory 9a, or to select all stored messages at random every time. Information is output to the occupant when boarding.

  The control unit 2 controls each audio means such as the CD player 9, the DSP circuit 8, and the audio amplifier 10 according to the operation of the audio operation unit 7, and outputs message information according to the ON / OFF of the door switch 3. , Stop, and control the output amount (volume). The output amount (volume) is set by a volume switch provided in the audio operation unit 7. Further, the control unit 2 has a message output function for outputting message information stored in the memory 9a to the occupant when the user gets on the vehicle in the parked state.

  Specifically, the message output function executed by the controller 2 is performed according to the routines shown in FIGS.

  3 and 4 is executed every predetermined calculation cycle. First, in step S1, if an unlocking signal transmitted from the control unit 23 of the door locking / unlocking unit 21 is not received, the routine is executed. When the unlock signal transmitted from the control unit 23 is received, the process proceeds to step S2. In step S2, the value of the timer flag Ft is checked. The timer flag Ft is set by a timer flag setting routine, which will be described later. The timer flag Ft is set until the set time Tco elapses after the ignition switch 5 is turned off (Ft = 1), and the set time Tco elapses. When cleared, it is cleared (Ft = 0). The processing in the timer flag setting routine will be described later.

  When Ft = 0, since the set time Tco has elapsed after the ignition switch 5 is turned OFF, the process proceeds to step S3. When Ft = 1, since the set time Tco has not yet elapsed after the ignition switch 5 is turned off, the routine is terminated. Therefore, for example, when the ignition switch 5 is turned off and the engine is stopped, the vehicle temporarily leaves the vehicle and gets on within the set time Tco, because the timer flag Ft is set (Ft = 1) The routine is terminated. Therefore, message information is not output from the speaker 12.

  If it is determined that Ft = 0 and the process proceeds to step S3, the audio power source, which is a system power source, is turned on to enter a standby state. Thereafter, it is determined whether or not a preset time has elapsed in step S4. If not, the process proceeds to step S5 and waits until the door switch 3 is turned on (door open). If it has elapsed, the process branches to step S6 to turn off the audio power and exit the routine.

  When the door switch 3 is turned on, the process proceeds from step S5 to step S7, and this time, it waits until the door switch 3 is turned off (door closed).

  When the door switch 3 is turned OFF, the process proceeds to step S8, and it is checked whether or not a signal from the portable device 31 is received by the indoor antenna 22b provided in the transmission / reception unit 22 of the door locking / unlocking unit 21. That is, in steps S5, S7, and S8, the user's boarding is determined from a series of situations in which the door switch 3 is once turned on and then turned off, and the portable device 31 is detected in the passenger compartment.

  And when the signal from the portable device 31 is received with the indoor antenna 22b provided in the transmission / reception part 22 of the door locking / unlocking unit 21, it progresses to step S9. When the indoor antenna 22b does not receive a signal from the portable device 31, the routine is terminated.

  As a result, for example, when the user once opens the door and then closes it without getting in, the portable device 31 is not detected in the vehicle interior, so that message information is not output in the vehicle interior. Similarly, when a baggage is loaded or unloaded from the vehicle with the door open, the door switch 3 is in an ON state, so that a signal from the portable device 31 is received by the indoor antenna 22b. However, no message information is output.

  When the portable device 31 is detected by the indoor antenna 22b and the process proceeds to step S9, the message information stored in the memory 9a is output. This message information is previously selected by a preset switch provided in the audio operation unit 7.

  Then, the message information is amplified by the audio amplifier 10 via the DSP circuit 8 and then output from the speaker 12. As a result, at the moment when the user gets on and closes the door, message information such as pre-selected music is flowed from the speaker 12 into the room.

  Thereafter, when proceeding to step S10, the count time Tm of the message counter timer is incremented (Tm ← Tm + 1), and the count time Tm is compared with the set time Tmo (for example, a value corresponding to 1 [min]) in step S11. . The setting time Tmo can be arbitrarily variably set using a music selection button or the like provided in the audio operation unit 7.

  If Tm <Tmo, the process branches to step S12. If Tm ≧ Tmo, the process proceeds to step S13. If it progresses to step S12, it will be determined based on the signal from the driving start operation detection part 6 whether driving start operation exists. Since the operation start operation detection unit 6 has already been described, the description thereof is omitted. If it is determined that there is a driving start operation, the process proceeds to step S13. If it is determined that there is no operation to start, the process returns to step S9 to continue outputting message information.

  Thereafter, when the process proceeds from step S11 or step S12 to step S13, output of the message information is stopped, and in step S12, the count time Tm is cleared (Tm ← 0), and the routine is ended.

  Further, the value of the timer flag Ft read in step S3 described above is set by the timer flag setting routine shown in FIG. This timer flag setting routine is executed at every setting calculation cycle. First, in step S21, it is checked whether or not the ignition switch 5 is OFF. If the ignition switch 5 is ON, the timer flag setting routine waits until the OFF operation is performed. When the ignition switch 5 is turned OFF, the process proceeds to step S22, the count time Tc of the flag counter timer is incremented (Tc ← Tc + 1), and the process proceeds to step S23.

  In step S23, the count time Tc of the counter timer is compared with a set time Tco (for example, a value corresponding to 30 [min]). When Tc <Tco, the process proceeds to step S24, and the timer flag Ft is set ( Ft ← 1), the process returns to step S21. On the other hand, when Tc ≧ Tco, the process proceeds to step S25, the timer flag Ft is cleared (Ft ← 0), then the process proceeds to step 26, the count time Tc is cleared (Tc ← 0), and the routine is exited.

  Therefore, in this routine, after the ignition switch 5 is turned OFF, the timer flag Ft is set (Ft ← 1) until the set time Tco elapses. When the set time Tco is reached, the timer flag Ft is cleared. (Ft ← 0).

  Thus, in this embodiment, when the door locking / unlocking unit 21 unlocks the door lock by mutual communication with the portable device 31 carried by the user, the audio power is turned on and the standby state is set. Even after the user opens the door, even if he gets on quickly and closes the door, the information input / output unit 1 is started up with sufficient time, so that the message information can be output with certainty. Can fully satisfy the expectations.

  In addition, when the door is closed with the portable device 31 not in the passenger compartment, that is, when the user closes the door without getting on, message information is not output, so that the user can feel secure. . In the present embodiment, since the user's boarding is detected by detecting the portable device 31 in the passenger compartment, it is not necessary to provide a special sensor such as a seating sensor, and the handling is good. In this case, since the message information is output even when the user gets on the passenger seat or the rear seat, the commercial value can be further increased. Furthermore, message information does not flow when a user carries in or out a package with the door open, so that the user does not feel uncomfortable.

  In addition, if the user starts the operation such as inserting the key into the key groove after sitting in the driver's seat, the message information is stopped, so even if the user starts immediately after getting on the message Information does not continue to flow, and the user does not feel uncomfortable.

  Furthermore, the time after the ignition switch 5 is turned off by the timer counter is timed, and message information is not output until the set time Tco has elapsed. However, the message information is not output one by one, and the user does not feel uncomfortable.

  In the present embodiment, message information is not output until the set time Tco elapses after the ignition switch 5 is turned off. Instead, until the set time Tco elapses. The output amount may be regulated so as to be reduced compared to the output amount after the set time Tco has elapsed.

  The present invention is not limited to the above-described embodiment. For example, the vehicle information input / output unit may use a car navigation function instead of a car audio function. Further, the message information may be in any form as long as it is audio information or visual information from the in-vehicle device, for example, an image displayed on a monitor.

  In this embodiment, message information is output when the door is closed. However, the present invention is not necessarily limited to this mode. For example, the door antenna may be detected by an indoor antenna regardless of the detection result of the door closing after the door is opened. When it is detected that the portable device is in the passenger compartment, message information may be output. In this way, message information is output even when the door is open, so that it is possible to output message information, which is effective when the message information is to be heard by another person. In addition, a specification that outputs message information after closing the door and a specification that outputs message information depending on the presence of the portable device in the passenger compartment are prepared regardless of the detection result of the door closing, and these specifications are prepared by the user. The user-friendliness can be improved by making it possible to select any of the above.
