JP 2004-264196 A

  By the way, when it is assumed that the device that performs the opening process with the ignition operation as described above and the device that performs the opening process with the accessory operation are mounted on the same vehicle, respectively, the ignition operation and the accessory operation are generally Since each is performed with a time difference, normally, the opening process at the time of the ignition operation and the opening process at the time of the accessory operation are performed separately and independently. However, if both opening processes are performed independently, a difference in start timing of the opening process may occur, giving the driver a sense of incongruity and resulting in inconveniences that reduce the merchantability.

  The present invention has been made in view of the above points, and by reducing the start timing of the opening process at the time of the ignition operation and the start timing of the opening process at the time of the accessory operation, the uncomfortable feeling given to the driver is reduced. An object is to provide an in-vehicle control system.

  The above-mentioned purpose is that an accessory device that is activated by switching the accessory power supply from OFF to ON and that performs an opening process at startup, and an ignition device that is activated by switching the ignition power supply from OFF to ON and that performs an opening process at startup, and Is achieved by an in-vehicle control system including synchronization means for synchronizing the timing for starting the opening process of the accessory device and the timing for starting the opening process of the ignition device. Is done.

  In the invention of this aspect, the synchronization means synchronizes the timing for starting the opening process of the accessory device and the timing for starting the opening process of the ignition device. If the start timings of both opening processes are synchronized, the uncomfortable feeling given to the driver is reduced.

  In the above-described on-vehicle control system, the synchronization unit includes an IG information supply unit that supplies ignition accessory on / off information to the accessory device, and an accessory device built-in, and the accessory power source is switched from off to on. And start processing control means for starting an opening process at the start after the ignition power supply is switched from off to on based on the on / off information supplied by the IG information supply means.

  In the invention of this aspect, the accessory device is supplied with the ignition power on / off information, and starts an opening process at the time of startup based on the information and the accessory power on / off information. For this reason, the start timing of the opening process of the ignition device and the start timing of the opening process of the accessory device can be synchronized.

  In this case, the ignition device starts the opening process when a first predetermined time has elapsed since the ignition power source was switched from off to on, and the start processing control means is configured to turn off the ignition power source. The opening process of the accessory device may be started when the first predetermined time has elapsed since the switch from ON to ON.

  Further, in the above-described in-vehicle control system, when the ignition power supply is not switched from off to on before the second predetermined time elapses after the accessory power supply is switched from off to on, the synchronization is performed. What is necessary is just to provide the synchronization cancellation means to cancel the synchronization by a means.

  In the aspect of the invention, if the ignition power supply is not switched from off to on even if the accessory power supply is switched from off to on, the synchronization by the synchronization means is stopped. In this case, the accessory device can start the opening process thereafter. Therefore, according to the present invention, it can be avoided that the opening process of the accessory device is not performed due to the ignition power supply not being switched from off to on.

  In this case, the accessory device may start the opening process when the second predetermined time elapses when the synchronization by the synchronization unit is canceled by the synchronization cancellation unit.

  By the way, in the above-described in-vehicle control system, the opening process of the accessory device is to output opening music from a speaker, and the opening process of the ignition device is to perform an opening display in the meter. Good.

  ADVANTAGE OF THE INVENTION According to this invention, the discomfort given to a driver | operator can be reduced by synchronizing the start timing of the opening process at the time of ignition operation of a vehicle, and the start timing of the opening process at the time of accessory operation.

  The meter ECU 20 drives the meter display 22 so as to display various information regarding the current vehicle state based on the input states of various sensors and various switches in a situation where the ignition power is on. The meter display 22 is a combination meter that can display various types of information on a vehicle disposed in front of a driver seat on which a vehicle driver is seated, and displays in accordance with a command from the meter ECU 20 when the ignition power is on. I do.

  The audio head unit 12 includes an audio ECU 30 mainly composed of a computer, and a speaker 32 connected to the audio ECU 30. On / off information (ACC information) of accessory power supply to which power is supplied or stopped by accessory operation by the driver is input to the audio ECU 30 via the communication bus 34. The audio head unit 12 is an accessory device that is activated when the accessory power source is switched from off to on, and is operable in a situation where the accessory power source is on, but is inoperable in a situation where the accessory power source is off. .

  The audio ECU 30 drives the speaker 32 so as to output predetermined music and voice based on input states of various switches and the like in a situation where the accessory power supply is on. The speaker 32 is provided in the vehicle interior, and performs music / audio output in accordance with a command from the audio ECU 30 in a situation where the accessory power supply is on.

  The navigation device 14 includes a navigation ECU 40 mainly composed of a computer, and a navigation display 42 connected to the navigation ECU 40. The ACC information of the accessory power supply is input to the navigation ECU 40 via the communication bus 34. The navigation device 14 is an accessory device that is activated when the accessory power source is switched from off to on, and is operable in a situation where the accessory power source is on, but is inoperable in a situation where the accessory power source is off.

The navigation display 42 is a multi-information display capable of displaying a road map or the like disposed near the center of the instrument panel, and performs display in accordance with a command from the navigation ECU 40 in a situation where the accessory power is on.

  Next, with reference to FIG.2 and FIG.3, operation | movement of the vehicle-mounted control system of a present Example is demonstrated. FIG. 2 shows a time chart of processing executed in the in-vehicle control system of the present embodiment. FIG. 3 shows a flowchart of an example of a control routine executed by the audio ECU 30 of the audio head unit 12 in the in-vehicle control system of the present embodiment.

  In the in-vehicle control system of the present embodiment, the audio head unit 12 and the navigation device 14 that are accessory devices are activated when the accessory power source is switched from off to on, and are deactivated when the accessory power source is switched from on to off. The Further, the meter device 10 that is an ignition device is activated when the ignition power source is switched from OFF to ON, and is deactivated when the ignition power source is switched from ON to OFF.

  The meter device 10 starts an opening process using the meter display 22 when a first predetermined time T1 has elapsed since the ignition power supply was switched from off to on. The meter ECU 20 instructs the meter display 22 to perform a meter opening process when a first predetermined time T1 has elapsed since the ignition power supply was switched from off to on.

  The first predetermined time T1 described above is a time required from the start (initialization) of the meter device 10 until it can be reliably operated, and is set to 800 milliseconds, for example. . Further, the meter opening process described above is for visually informing the vehicle driver that the operation (display) of the meter device 10 is started by switching the ignition power source from OFF to ON by the ignition ON operation by the vehicle driver. This is to perform display with a predetermined effect. The meter opening process is continuously performed for a predetermined period after the start.

  In addition, the navigation device 14 starts an opening process using the navigation display 42 when the second predetermined time T2 has elapsed since the accessory power supply was switched from off to on. The navigation ECU 40 instructs the navigation display 42 to perform a navigation opening process when a second predetermined time T2 has elapsed since the accessory power supply was switched from OFF to ON.

  The second predetermined time T2 described above is a time required until the operation of the navigation device 14 is started after the start of the navigation device 14, and is longer than at least the first predetermined time T1 described above. It is set to 2 seconds. In addition, the above-described navigation opening process visually indicates to the vehicle driver that the operation (display & sound output) of the navigation device 14 is started when the accessory power source is switched from OFF to ON by the accessory ON operation by the vehicle driver. Display with a predetermined effect for informing the user. The navigation opening process is continuously performed for a predetermined period from the start.

  By the way, the audio head unit 12 described above is an accessory device that is activated by switching the accessory power source from off to on, similarly to the navigation device 14, and thus is determined in advance after the accessory power source is switched from off to on. The opening process may be started when time elapses. However, since the accessory-on operation and the ignition-on operation are generally performed with a time difference, in this configuration, the opening process of the audio head unit 12 and the meter opening process of the meter device 10 are performed separately and independently. In other words, the start timing of both opening processes may be shifted, and the vehicle driver may feel uncomfortable.

  Therefore, the in-vehicle control system of this embodiment synchronizes the start timing of the opening process of the audio head unit 12 and the start timing of the meter opening process of the meter device 10. Hereinafter, the characteristic part of a present Example is demonstrated.

  That is, in the in-vehicle control system of the present embodiment, the IG information of the ignition power source is input to the audio ECU 30 of the audio head unit 12 via the communication bus 24.

  The audio ECU 30 determines whether or not the accessory power source has been switched from off to on based on the ACC information of the accessory power source input via the communication bus 34 (step 100). As a result, if it is determined that the accessory power source has been switched from OFF to ON, then the ignition power source is switched from OFF to ON based on the IG information of the ignition power source input via the communication bus 24. It is determined whether or not the operation has been performed (step 102).

  As a result, if it is determined that the ignition power source has been switched from off to on, then whether or not the first predetermined time T1 has elapsed since the ignition power source was switched from off to on Is determined (step 104). The first predetermined time T1 is the time required from the start of the meter device 10 until the operation can be surely performed as described above.

  If it is determined that the first predetermined time T1 has elapsed since the ignition power supply was switched from OFF to ON, an opening process using the speaker 32 is performed (step 106). That is, the audio ECU 30 instructs the speaker 32 to perform an opening process when the first predetermined time T1 has elapsed since the accessory power source was switched from OFF to ON and the ignition power source was switched from OFF to ON. .

  The opening process of the audio head unit 12 indicates that the operation of the audio head unit 12 (output of music and voice) can be started by switching the accessory power source from off to on by the accessory on operation by the vehicle driver. This is to perform output (start-up BGM ringing) with a predetermined effect for audibly informing the driver. Then, this opening process is continuously performed for a predetermined period from the start.

  If it is determined in step 102 that the ignition power source has not been switched from off to on, then the second predetermined time T2 has elapsed since the accessory power source was switched from off to on. It is determined whether or not it has elapsed (step 108). Note that the second predetermined time T2 is the time required from the start of the navigation device 14 to the time when it can be reliably operated, as described above.

  As a result, if it is determined that the second predetermined time T2 has not elapsed since the accessory power supply was switched from off to on, the processing of step 102 is repeated. On the other hand, if it is determined that the second predetermined time T2 has elapsed since the accessory power supply was switched from off to on, the opening process using the speaker 32 described above is performed (step 106).

  Thus, in the in-vehicle control system of the present embodiment, the opening process using the speaker 32 that is performed when the audio head unit 12 that is one of the accessory devices is switched from the accessory power supply OFF to the ON is performed by the accessory power supply. This is started when the first predetermined time T1 has elapsed since the ignition power source was switched from off to on after the switch from off to on. In other words, the meter display 22 is used for the start timing of the opening process of the audio head unit 12 when the accessory power source is switched from off to on when the meter device 10 as the ignition device switches from the ignition power source to off. It can be synchronized with the start timing of the meter opening process.

  If the start timing of the opening process of the audio head unit 12 and the start timing of the opening process of the meter device 10 are synchronized, the sound output from the speaker 32 and the display of the meter display 22 by the opening process are started without time lag. Therefore, it is possible to prevent the vehicle driver who can listen to the sound from the speaker 32 and see the display on the meter display 22 from feeling uncomfortable due to the time difference between the start of both opening processes. It will be.

  Therefore, according to the vehicle-mounted control system of the present embodiment, it is possible to reduce the uncomfortable feeling given to the vehicle driver regarding the start timing of the opening process of the audio head unit 12 and the opening process of the meter device 10.

  Even if the accessory power source is switched from off to on, for example, when the vehicle occupant listens to music in the passenger compartment without driving while the vehicle is stopped, the ignition power source is switched from off to on. Sometimes not done at all. In this case, if the requirement for switching the ignition power supply from off to on imposed on the execution of the opening process of the audio head unit 12 is strictly applied, the opening process is not performed at all.

  On the other hand, in the in-vehicle control system of the present embodiment, the ignition power supply is switched from off to on before the second predetermined time T2 elapses after the accessory power supply is switched from off to on. Otherwise, the synchronization between the start timing of the opening process of the audio head unit 12 and the start timing of the meter opening process of the meter device 10 is stopped, and when the second predetermined time T2 elapses, the audio head unit 12 The opening process is started.

  In other words, the opening process of the audio head unit 12 is started when the second predetermined time T2 elapses after the accessory power source is switched from off to on, even if the ignition power source is not switched from off to on. . Therefore, according to the present embodiment, it is possible to prevent the opening process of the audio head unit 12 as the accessory device from being performed due to the ignition power source not being switched from OFF to ON. Thus, the opening process of the audio head unit 12 when the accessory power is turned on can be reliably executed.

  In this case, the start timing of the opening process of the audio head unit 12 is synchronized with the start timing of the navigation opening process using the navigation display 42 that is performed when the navigation device 14 as the accessory device switches from the accessory power supply to the on state. Is done. If such synchronization is performed, the sound output from the speaker 32 and the display on the navigation display 42 by the opening process are started without time lag, so that the user can listen to the sound from the speaker 32 and display on the navigation display 42. As a result, the effect of performing both opening processes on the vehicle driver who can see the vehicle is enhanced.

  Therefore, according to the vehicle-mounted control system of the present embodiment, the ignition power source is not switched from off to on before the second predetermined time T2 elapses after the accessory power source is switched from off to on. Then, when the synchronization between the start timing of the opening process of the audio head unit 12 and the start timing of the meter opening process of the meter device 10 is stopped, the opening process of the audio head unit 12 and the opening process of the navigation device 14 are started. Synchronizing the timing, it is possible to enhance the production effect by executing both opening processes.

  By the way, in the above-described embodiment, the meter device 10 supplies the IG information to the “ignition device” described in the claims, the audio head unit 12 stores the IG information in the “accessory device” described in the claims, and the audio head unit. The communication bus 24 to be supplied to 12 is connected to the “synchronizing means” and “IG information supplying means” described in the claims, and the audio ECU 30 of the audio head unit 12 switches the accessory power source from off to on and turns off the ignition power source. The start-up BGM is started to sound from the speaker 32 when the first predetermined time T1 has elapsed since switching from ON to ON is performed. Respectively.

  In the above-described embodiment, the opening process of the navigation device 14 as an accessory device is started when the second predetermined time T2 has elapsed since the accessory power supply was switched from off to on. The start timing of the opening process of the meter device 10 is a time when the first predetermined time T1 has elapsed since the ignition power supply was switched from off to on, and the audio head unit 12 and the navigation device 14 that are accessory devices On the other hand, the start timing of the opening process of one audio head unit 12 is synchronized with the start timing of the opening process of the meter device 10 which is an ignition device, but the present invention is not limited to this, and the other navigation The start timing of the opening process of the device 14 may be synchronized with the start timing of the opening process of the meter device 10 without being fixed when the second predetermined time T2 has elapsed since the accessory power supply was switched from OFF to ON. Good.

  In the above embodiment, only the start timing of the opening process of one of a plurality of accessory devices is synchronized with the start timing of the opening process of the ignition device. The start timing of the opening process may be synchronized with the start timing of the opening process of the ignition device.

  In the above embodiment, in order to perform the opening process of the audio head unit 12 as an accessory device, in principle, it is necessary to switch the ignition power source from OFF to ON, and the ignition power source is switched from OFF to ON. The opening process is started when a predetermined time T1 elapses. However, when the time required for activation (initialization) of the accessory device is longer than the time required for activation of the ignition device (for example, this embodiment) In the relationship between the navigation device 14 and the meter device 10 in the example), the start timing side of the opening process of the accessory device is not matched with the start timing side of the opening process of the ignition device. Supplied to the ignition device via the communication bus 34 Above, it is also possible to adjust the start timing side of the opening process of the ignition device to start timing side of the opening process of the accessory device.

  In this case, after the communication ECU 34 for supplying the ACC information of the accessory power source to the ignition device and the meter ECU 20 of the meter device 10 switching the ignition power source from OFF to ON, the accessory power source is switched from OFF to ON. When the second predetermined time T <b> 2 has elapsed since the start, the meter display 22 starts the meter opening process, which corresponds to “synchronization means” described in the claims.

  In the above embodiment, if the ignition power supply is not switched from off to on before the second predetermined time T2 elapses after the accessory power supply is switched from off to on, At the elapse of the second predetermined time T2, the synchronization between the start timing of the opening process of the audio head unit 12 and the start timing of the meter opening process of the meter device 10 is stopped, and the opening process of the audio head unit 12 is started. I am going to do that. In such a configuration, immediately before the second predetermined time T2 has elapsed since the accessory power supply was switched from OFF to ON (specifically, before the elapsed time, within the first predetermined time T1). When the ignition power supply is switched from OFF to ON, the opening process of the audio head unit 12 is performed. More precisely, the second predetermined time T2 elapses after the accessory power supply is switched from OFF to ON. The first predetermined time T1 has elapsed since the ignition power supply was switched from off to on, which is the same as the opening timing of the opening process of the meter device 10, after the second predetermined time T2 has elapsed. It will start at the time.

  However, the present invention is not limited to this, and after the accessory power source is switched from OFF to ON, a time elapsed by subtracting the first predetermined time T1 from the second predetermined time T2 has elapsed. If the ignition power supply is not switched from off to on before starting, the synchronization between the start timing of the opening process of the audio head unit 12 and the start timing of the meter opening process of the meter device 10 is stopped, and the second When the predetermined time T2 elapses, the opening process of the audio head unit 12 may be started. In such a configuration, immediately before the second predetermined time T2 has elapsed since the accessory power supply was switched from OFF to ON (specifically, before the elapsed time, within the first predetermined time T1). When the ignition power source is switched from OFF to ON, the opening process of the audio head unit 12 starts when the second predetermined time T2 has elapsed since the accessory power source was switched from OFF to ON. Will be.

  Further, in the above embodiment, the audio head unit 12 and the navigation device 14 are used as accessory devices, and the meter device 10 is used as an ignition device. However, when the accessory power source is switched from off to on, or the ignition power source. As long as the opening process is performed at the time of switching from OFF to ON, the present invention is not limited to the above devices and devices 10 to 14, and other devices and devices may be used.
