  By the way, when the vehicle is traveling on a congested road or a winding road (winding road) such as a saddle road, it may be difficult for the driver to watch the display device. As means for notifying the driver of the shift instruction information, it is conceivable to use vibration, sound, or the like together. However, in-vehicle devices are not generally notified by vibration, which causes an increase in cost. The notification by sound may be stopped depending on the situation or preference, for example, when there is a passenger. Such a problem has been newly found in the process in which the present inventors have continued intensive research with the intention of improving the performance of a vehicle shift indicator.

  The present invention has been made in the background of the above circumstances, and an object of the present invention is to provide a vehicle shift indicator system for appropriately notifying a driver of a shift instruction.

As a notification mode, notification by sound, notification by vibration, or report by sound and vibration is performed. It is characterized in that the can be set either.

  In this way, the electronic control unit is arranged in the vehicle, and in accordance with the traveling state of the vehicle, a shift instruction that instructs an upshift or a downshift by a driver of a transmission provided in the vehicle. The portable information terminal receives the shift instruction information output from the electronic control unit and transmitted by the transmission unit, and outputs the shift instruction information by at least one of sound and vibration. As the notification mode, any one of notification by sound, notification by vibration, or notification by sound and vibration can be set as the notification mode. On the other hand, the shift instruction can be appropriately notified. Since a general portable information terminal has a function of generating sound and vibration in advance, an increase in cost can be suppressed by performing notification using at least one of sound and vibration via the portable information terminal. However, appropriate notification can be realized. Furthermore, the notification mode of the shift instruction information can be set according to the situation and preference. That is, it is possible to provide a vehicle shift indicator system that appropriately notifies the driver of a shift instruction.

For example, the transmission 24 is established on the basis of the vehicle speed V detected by the vehicle speed sensor 40 and the accelerator opening Acc detected by the accelerator opening sensor 42 based on a map stored in advance. The gear position to be determined is determined. If the determined shift stage corresponds to a lower speed ratio than the currently established shift stage in the transmission 24 (ie, a high-speed side shift stage), the upshift of the transmission 24 is performed. The shift instruction information for instructing is output. That is, shift instruction information corresponding to an instruction to perform an upshift of the transmission 24 is output. If the determined gear stage corresponds to a gear ratio higher than the gear stage established at that time in the transmission 24 (ie, a low speed gear stage), the downshift of the transmission 24 is performed.

A relatively low sound (at least a sound lower than the sound corresponding to the upshift notification) is output as the notification indicating the shift instruction information corresponding to the downshift. The sounds corresponding to these notifications are not to be confused with the mail ringtone when a mail is received at the portable information terminal 50 or the telephone ringtone when a telephone call is received. It is necessary to set a different frequency (pitch) or the like. Alternatively, a notification sound of a predetermined melody (melody) representing shift instruction information corresponding to upshift and a notification sound of a predetermined melody (melody different from the upshift notification sound) representing shift instruction information corresponding to downshift are preliminarily provided. These notification sounds may be output as notifications indicating shift instruction information corresponding to upshifts and notifications indicating shift instruction information corresponding to downshifts.

  In the aspect 3 illustrated in FIG. 2, the shift instruction notification unit 54 outputs two sounds as notifications indicating shift instruction information corresponding to an upshift. One sound is output as notification indicating shift instruction information corresponding to downshift. In the present embodiment, the number of sounds is the number of appearances of the sound that continues for the specified time in a form in which a sound that lasts for a specified time and a break of specified time (a state in which no sound is output) are repeated. The sounds corresponding to these notifications are not to be confused with the mail ringtone when a mail is received at the portable information terminal 50 or the telephone ringtone when a telephone call is received. The frequency etc. need to be set differently.

  In the aspect 4 illustrated in FIG. 2, the shift instruction notification unit 54 vibrates twice as notification indicating shift instruction information corresponding to an upshift and outputs a relatively high sound. As a notification indicating the shift instruction information corresponding to the downshift, one vibration is performed and a relatively low sound (at least a sound lower than the sound corresponding to the upshift notification) is output. In each notification, vibration and sound are output in conjunction with each other (that is, simultaneously and substantially simultaneously). The vibration corresponding to the notification needs to be set so that the number of times and the vibration period are different from the vibration when the portable information terminal 50 receives mail or the vibration when there is an incoming call. . The sound corresponding to the notification needs to be set to a frequency that is different from that of a mail ring tone when a mail is received by the portable information terminal 50 or a telephone ring tone when a telephone call is received. .

  In the aspect 5 illustrated in FIG. 2, the shift instruction notification unit 54 vibrates twice as notification indicating shift instruction information corresponding to an upshift and outputs two sounds. As a notification indicating the shift instruction information corresponding to the downshift, one vibration is performed and one sound is output. In each notification, vibration and sound are output in conjunction with each other. The vibration corresponding to the notification needs to be set so that the number of times and the vibration period are different from the vibration when the portable information terminal 50 receives mail or the vibration when there is an incoming call. . The sound corresponding to the notification needs to be set to a frequency that is different from that of a mail ring tone when a mail is received by the portable information terminal 50 or a telephone ring tone when a telephone call is received. .

  In the aspect 6 illustrated in FIG. 2, the shift instruction notification unit 54 outputs a guidance voice “Please shift up” as notification indicating the shift instruction information corresponding to the upshift. As a notification indicating the shift instruction information corresponding to the downshift, a guidance voice “Please downshift” is output. The guidance voice corresponding to these notifications is preferably output by a voice guidance function provided in the portable information terminal 50. Alternatively, it may be output by a voice guidance function provided in the car navigation device 32.

  Although not illustrated in FIG. 2, the shift instruction notifying unit 54 indicates the shift instruction information according to the timing of the manual shift operation when a manual shift operation of the transmission 24 is performed by the driver. It may be what performs. For example, when shift instruction information is supplied from the engine control device 60, a manual shift operation corresponding to the shift instruction information of the transmission 24 is performed within a specified time period before and after the time when the supply is performed. In the event that it is interrupted, a guidance voice such as “good timing” is output. When a manual shift operation corresponding to the shift instruction information is performed after a lapse of a specified time from the time when the shift instruction information is supplied, a guidance voice such as “shift operation is too late” is output. When a manual shift operation corresponding to the shift instruction information is performed more than a predetermined time before the shift instruction information is supplied, a guidance voice such as “shift operation is too early” is output.

  In the aspect in which the car navigation device 32 is provided with a voice output device including a speaker and a voice guidance function, the shift instruction notification unit 54 transmits a sound as a notification representing the shift instruction information to the car navigation system. You may output from the audio | voice output apparatus in the apparatus 32. FIG. Specifically, a command to output a sound as a notification representing the shift instruction information is transmitted to the car navigation control device 80. The car navigation control device 80 outputs a sound as a notification representing the shift instruction information from the audio output device in the car navigation device 32 based on the supplied command. Alternatively, sound information generated by the portable information terminal 50 is transmitted to the car navigation control device 80 via the wireless communication units 52 and 82, and the sound information is transmitted from the sound output device in the car navigation device 32 to the sound information. A corresponding sound may be output.
