Moreover, in the following description, in order to make an understanding of this invention easy, description of a known technical matter is abbreviate | omitted suitably.

  The electric motorcycle 1 is a motorcycle powered by a motor. As shown in FIG. 1, the main components for explaining the present embodiment are a power unit 3, a tire 5, a battery 7, and an accelerator. 9, a display device 11, and a vehicle information acquisition unit 13.

  The power unit 3 includes a motor and a gear that transmits the power of the motor to the outside of the power unit 3. The power of the motor is transmitted to a shaft (not shown) through a gear. By this transmission, the shaft rotates, the tire 5 rotates by this rotation, and the electric motorcycle 1 travels. In this way, the power unit 3 rotates the tire 5 via the shaft and causes the electric motorcycle 1 to travel. The power unit 3 is controlled by the ECU 131 of the vehicle information acquisition unit 13.

  The battery 7 stores electric power, which is energy for operating predetermined components in the electric motorcycle 1, and supplies the electric power to the predetermined components. In particular, the motor of the power unit 3 is driven by electric power supplied from the battery 7.

  The accelerator 9 receives an accelerator operation from the user. For example, the accelerator 9 supplies an accelerator operation signal indicating a value corresponding to the operation amount of the accelerator operation to the vehicle information acquisition unit 13.

To do. The first predetermined period and the second predetermined period are basically the same, but may be different.

  The display device 11 communicates with the ECU 131 by CAN communication or the like, and displays a predetermined display screen based on the rotation speed information, the remaining amount information, and the like supplied from the ECU 131. Here, the display device 11 is an instrument (vehicle instrument) that displays the speed, travel distance, and the like of the electric motorcycle 1.

  The display device 11 includes a control unit 111, a storage unit 112, an input / output interface unit 113, a display unit 114, and an audio output unit 115.

  The control unit 111 (control unit) includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like. The CPU executes processing to be described later performed by the control unit 111 in accordance with a program recorded in the storage unit 112 and using information recorded in the flash memory 112a and the like. The control unit 111 also functions as a timer 111a. And the control part 111 calculates | requires the moving distance of an electric motorcycle from the rotation speed information supplied from ECU131 and the outer periphery length (predetermined value) of a wheel, for example, and calculated | required moving distance and the time measured by the timer 111a From (period), the speed of the electric motorcycle 1 is calculated. In addition, the control unit 111 is supplied from the ECU 131 with the calculated speed, an integrated value for the travel distance obtained above (the travel distance is appropriately recorded in the storage unit 112 and integrated). The remaining amount of the battery indicated by the remaining amount information is displayed on the display unit 114.

  The storage unit 112 stores predetermined information and the like. The storage unit 112 includes a flash memory 112a. In the flash memory 112a, in addition to storing programs, information (various data) used for processing performed by the control unit 111 is appropriately stored.

Hereinafter, the operation of the display device 11 will be described by taking as an example a case in which it is displayed immediately after the ignition switch is turned on that the electric motorcycle 1 is ready to start.

  In response to the ignition switch being turned on, the control unit 111 starts the start possible state display process shown in FIG. 3, and first resets the counter value (t) of the timer 111a to 0 to measure the time. Start (step S1). The control unit 111 calculates the speed of the electric motorcycle 1 from the rotation speed information supplied from the ECU 131 and the period measured by the timer 111a (step S2). The controller 111 determines whether or not the counter value (t) of the timer 111a is equal to or longer than a predetermined time (T1) (step S3). This time (T1) corresponds to a period during which the control unit 111 displays on the display unit 114 that the transmission is possible.

When the control unit 111 determines that the counter value (t) is less than the predetermined time (T1) (step S3; No), the control unit 111 determines whether the calculated speed of the electric motorcycle 1 is zero. That is, it is determined whether or not the electric motorcycle 1 is stopped (step S4).

Each segment for displaying the speed of the electric motorcycle 1 is sequentially blinked and dynamically displayed (animation display) (step S5).

That is, the display unit 114 that originally displays the speed of the electric motorcycle 1 indicates that the vehicle is ready to start. For this reason, it is not necessary to mount a display device only for displaying that the vehicle is ready to start, and the structure can be simplified. In addition, since no dedicated display device is provided, power consumption can be reduced.
Furthermore, since each segment for displaying the speed of the electric motorcycle 1 is blinked sequentially and displayed as an animation, it is easy for the operator to understand and perform a novel notification.

The control unit 111 changes the color of each segment in accordance with the timing of blinking each segment (step S6). For this reason, it is possible to prompt the operator to call attention and perform novel notification.
Further, the control unit 111 notifies the user that the vehicle is ready to start by outputting from the voice output unit 115 that the vehicle is ready to start (step S7). For this reason, the operator can be alerted by voice.
On the other hand, when it is determined that the calculated speed is not 0 (step S4; No), the control unit 111 displays the calculated speed on the display unit 114 (step S8).
Then, the control part 111 returns a process to step S2.

  On the other hand, when the control unit 111 determines that the counter value (t) is equal to or longer than the predetermined time (T1) (step S3; Yes), the control unit 111 advances the process to step S8.

  As described above, according to the present embodiment, each segment for displaying the speed of the electric motorcycle 1 is blinked sequentially instead of the speed for a predetermined period after the ignition switch is turned on. To display. For this reason, it is possible to suppress the manufacturing cost for notifying that the vehicle is ready to start without requiring dedicated hardware for notifying that the vehicle is ready to start. In addition, since the number of display items does not increase, a reduction in the visibility of the display unit 114 can be suppressed.
