Abstract

<P>PROBLEM TO BE SOLVED: To immediately stop the output of message information without requiring a specific operation when a driving start is operated even if the message information is outputted after a driver is seated. <P>SOLUTION: When a door switch 3 detects door opening, an audio power source is turned on (S3). When the door switch 3 thereafter detects door closing, the previously stored message information is outputted from a speaker 12 (S5). When the driver inserts a key into a key groove for starting driving while the message information is outputted, the output of the message information is immediately stopped (S8,S9). <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a vehicular information output device that outputs preset message information into a passenger compartment when a user gets into a vehicle.

  2. Description of the Related Art Conventionally, a desktop or notebook personal computer is known in which a commercial value is enhanced by expressing a so-called welcome message, which is message information, with video and sound when a start switch is turned on.

On the other hand, various technologies have also been proposed in which a welcome message is sounded when a vehicle is boarded. For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2005-346264), when a user represented by a driver opens a door, the system is turned on, then the door is closed, and the user's boarding is detected. In some cases, a technique for outputting a welcome message from the system is disclosed.
JP 2005-346264 A

  However, in the technique disclosed in the above-described document, since the message continues to be output until a certain time has elapsed after the welcome message is output, for example, when starting immediately after getting on, The welcome message may continue to be output, and some users may feel annoyed.

  In this case, if the power switch is forcibly turned off after the user gets on, the system is turned off, so that the welcome message can be stopped. There is an inconvenience that gives a sense of complexity.

  In the present invention, in view of the above circumstances, even when message information is output after the user is seated, if the driving start operation is performed, the message information is immediately output without performing a special operation. An object of the present invention is to provide a vehicle information output device that can be limited.

  In order to achieve the above object, an information output device for a vehicle according to the present invention includes an output means for outputting message information stored in advance, a door opening / closing detection means for detecting opening / closing of a door, and a driving start for detecting a driving start operation. An operation detecting means; and a control means for turning on the output means when the door opening / closing detecting means detects opening of the door, and outputting the message information from the output means when detecting the closing of the door. The control means limits the output amount of the message information when a driving start operation is detected by the driving start operation detecting means.

  According to the present invention, when the driving start operation is performed, the output amount of the message information is automatically limited, so that the message information is not continuously output during traveling. As a result, after the operation start operation, a special operation for restricting the output of the message information becomes unnecessary, and good operability can be obtained.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[First Embodiment]
1 to 3 show a first embodiment of the present invention. FIG. 1 is an overall configuration diagram of a vehicle information output device. A vehicle information output device 1 shown in FIG. 1 is configured by using a function provided in a car audio device in the present embodiment.

  The vehicle information output device 1 has an electronic control unit (ECU) 2 as control means, and audio control is performed by the ECU 2. The ECU 2 is connected with a door switch 3 as a door opening / closing detection means, a recording switch 4, an ignition switch 5, and a driving start operation detecting section 6 as a driving start operation detecting means, as well as an audio operating section 7 and a DSP ( Digital Signal Processor) circuit 8 is connected.

  The driving start operation detection unit 6 is a series of operations that are performed when a user (in many cases, a driver is described as a “driver” in the following description because the driver is a driver) tries to start traveling. Thus, it is a generic term for each operation start state that can be detected by the sensor / switch, and when any of the sensors / switches detects the operation start operation, the operation start operation is determined. In addition, as a sensor switch for detecting the operation start operation, a key insertion detection switch that is turned on when the key is inserted into the key groove, an accessory switch that is turned 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 detected by a vehicle speed sensor, 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, in the key operation, when the audio switch provided in the audio operation unit 7 is turned ON before the start of driving is detected, this may be determined as the driving 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. Further, the audio amplifier 10 is connected to a speaker 12 as audio output means for outputting auditory information as message information, 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. Note that the door switch 3 according to the present embodiment is intended for the driver seat side, but all door switches of the vehicle may be connected to the ECU 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, a personal message, and the like. In addition, as a standard message, a plurality of information such as music, voice, and video representing hospitality at the time of boarding are stored, and as a personal message, the driver dubbed music from the CD player 9 or input through the microphone 13 Audio can be stored. 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 selects one message information from a plurality of message information stored in the memory 9a, or selects all stored message information at random every time. Message information is output when boarding.

  The ECU 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 and stops message information according to ON / OFF of the door switch 3. And the output amount (volume) is controlled. The output amount (volume) is set by a volume switch provided in the audio operation unit 7. Further, the ECU 2 has a message information output function for outputting message information stored in the memory 9a when a driver or the like gets on a vehicle in a parked state.

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

  The boarding message information output routine shown in FIG. 2 waits until the door switch 3 is turned on (door open) in step S1, and proceeds to step S2 when it is determined that the door switch 3 is turned on. . 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, and is set until a preset time Tco (hereinafter referred to as “set time Tco”) elapses after the ignition switch 5 is turned off. Cleared (Ft = 1) and cleared when the set time Tco has elapsed (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) No message information is output from the speaker 12 or the like.

  If it is determined that Ft = 0 and the process proceeds to step S3, the audio power supply is turned on to enter a standby state, and the process waits until the door switch 3 is turned off (door closed) in step S4.

  When it is determined that the door switch 3 is OFF and the door is closed, the process proceeds to step S5. In step S5, 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 or the like. As a result, when the driver opens the door and gets on and closes the door, message information such as pre-selected music is flowed into the room from the speaker 12 or the like.

  Thereafter, when proceeding to step S6, the count time Tm of the message information counter timer is incremented (Tm ← Tm + 1), and the count time Tm and a time Tmo set in advance at step S7 (for example, a value corresponding to 1 [min]. , Referred to as “set time Tmo”). 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 S8. If Tm ≧ Tmo, the process proceeds to step S9. If it progresses to step S8, 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 S9. If it is determined that there is no operation to start, the process returns to step S5 to continue outputting message information.

  Then, when the process proceeds from step S7 or step S8 to step S9, the output of the message information is limited (stopped in this embodiment), and the routine is terminated.

  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 value 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 S22. On the other hand, when Tc ≧ Tco, the process proceeds to step S25, the timer flag Ft is cleared (Ft ← 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).

  As described above, in this embodiment, when the driver opens the door (the door switch 3 is ON), gets on the vehicle, and then closes the door (the door switch 3 is OFF), the message information is composed of audio information such as music. Automatically flows from the speaker 12, and then the message information is stopped when an operation start operation such as inserting a key into the keyway is performed. Therefore, for example, even if the driver starts immediately after getting on, message information is not continuously output, and the driver does not feel uncomfortable. Further, since a troublesome operation for forcibly stopping the message information as in the prior art is not required, good operability can be obtained.

  In addition, the time after the ignition switch 5 is turned off by the timer counter is timed, and message information is not output even if the door is opened and closed until the set time Tco elapses. Even if the car is temporarily away from the vehicle for easy shopping, or when the door is opened or closed when loading or unloading the vehicle, message information is not output one by one, giving the driver discomfort. There is no.

[Second Embodiment]
FIG. 4 shows a boarding message information output routine according to the second embodiment of the present invention. This routine is a modification of the routine shown in FIG. 2 of the first embodiment described above. The difference is that when it is determined in step S8 that there is an operation start operation, the message information is not stopped and the output amount (this embodiment) is changed. In the embodiment, the volume) is reduced.

  Accordingly, steps S1 to S8 and step S9 of this routine are the same as those in the first embodiment, and thus description thereof is omitted.

  If it is determined in step S8 that there is a driving start operation, the process proceeds to step S31, the output amount of message information is limited (reduced in the present embodiment), and the process returns to step S5. Then, message information with a reduced output amount is output in step S4.

  Therefore, in this embodiment, even when it is determined that there is a driving start operation, the message information continues to be output until the count time Tm of the message information counter timer reaches the set time Tmo. The output amount instructed in step S31 can be adjusted by operating a volume switch provided in the audio operation unit 7.

  Thus, in this embodiment, even if it is determined that there is a driving start operation, the message information is not stopped, so for example, when the driver's favorite music is recorded as message information, it is listened to the end. Can do.

[Third Embodiment]
FIG. 5 shows a boarding message output routine according to the third embodiment of the present invention. This routine is a modification of the routine shown in FIG. 2 of the first embodiment described above. The difference is that after the message information is output in step S5, the states of all the door switches 3 are checked in step S41. When the door switch 3 is ON, the process jumps to step S9 to immediately stop the message information. Processing other than step S41 is the same as the processing performed in each step of FIG. 2 of the first embodiment described above.

  That is, in this routine, after message information is output in step S5, the state of all door switches 3 is checked in step S41, and if all door switches 3 are in the OFF state, the process proceeds to step S7. On the other hand, when at least one door switch 3 is ON, the process jumps to step S9.

  As a situation where the door switch 3 is turned off once and then turned on without opening the door, a half door can be considered. In this embodiment, when a half door is detected in any of the door switches, the message information is immediately stopped, so that the driver's expectation that the message information can be listened to normally is hindered. The person can immediately recognize that it is a half-door.

  The present invention is not limited to the above-described embodiment. For example, the vehicle information output apparatus may be configured using a car navigation function instead of a car audio function. Further, the message information is not limited to auditory information, but may be visual information from an in-vehicle device, or both auditory information and visual information. As visual information, for example, there is an image displayed on a monitor. In this case, the video output means for outputting visual information is a monitor. When message information is displayed on the monitor, the output amount processed in step S31 of the second embodiment can be reduced by reducing the brightness of the monitor. Further, the output amount of the message information may be faded out (after being reduced in steps, it is stopped before the count time Tm of the message information counter timer reaches the set time Tmo).
