In addition, inside the throttle grip 13 for adjusting the speed of the electric motorcycle 1, the notification means 1 is provided.
A vibration generator 12B as a second embodiment of No. 2 (the detailed structure will be described later) is provided.

Next, with reference to the block diagram shown in FIG. 2, the connection state of each of the means and devices will be described.

The control device S as the control means is composed of, for example, a one-chip microcomputer or the like,
In the control device S, the main switch MS, the voltage sensor 6 as the battery voltage detecting means, the speed sensor 9 as the state detecting means, the alarm device 12A and the vibration generating device 12B as the notifying means 12, and the read-only A ROM 14 as a memory is connected.

The sounding device 12A is composed of, for example, a speaker having an amplifier, and based on a sound signal output from the control device S, sounds a notification sound imitating an engine sound, for example. There is.

Program data for controlling the controller S, sound data D stored as a memory map, and the like are stored in a predetermined storage area of the ROM 14.

The sound data D has a predetermined correlation between the battery voltage level detected by the voltage sensor 6 and the speed detected by the speed sensor 9, as shown in the memory map of FIG. It is stored with.

That is, for example, in the case where the speed is zero (that is, the electric motor cycle 1 is stopped) and the voltage level of the battery 3 is close to full charge, the engine idling sound is generated. The simulated large-volume continuous sound data D1 is stored, and the continuous sound data of the same sound quality in which the volume gradually decreases as the voltage level decreases is stored over a plurality of stages (D2 to D6).

Further, even at the same voltage level, as the speed gradually increases, for example, D1 → D7 → D13 → D19 → ...

The operation of the electric motorcycle 1 provided with the sound output device 12A will be described as the first embodiment of the present invention.

First, when the driver inserts a start key (not shown) and operates the main switch MS to turn it on, the control device S, the voltage sensor 6, the speed sensor 9, etc. are activated. Start.

Then, the speed sensor 9 outputs, for example, a signal indicating a zero speed state (that is, a stopped state in which the electric motor cycle 1 can start) to the control device S, and the voltage sensor 6 outputs, for example, When a detection signal indicating that the voltage level of the battery 3 is high (that is, a state close to full charge) is output to the control device S,
The microcomputer constituting the control device S reads out the sound data D1 corresponding to the state from the memory map of the predetermined storage area of the ROM 14 according to the predetermined program data and outputs it to the speaker constituting the alarm device 12A. To do.

Then, the sound emitting device 12A produces a large-volume continuous sound simulating the engine idling sound based on the sound data D1.

As a result, the driver can hear the fact that the electric motorcycle 1 is ready to start, the voltage of the battery 3 is sufficiently high, and the speed is high, so that a sudden throttle is applied. Care can be taken not to perform operations.

Further, in the case of outputting the sound imitating the engine sound as in the present embodiment, it becomes possible to operate the vehicle without any discomfort even when the user changes from a conventional motorcycle equipped with an engine. .

As the voltage of the battery 3 decreases, the sound data (D1 to D6) read from the memory map of the ROM 14 changes, and the volume gradually decreases, for example. It is also possible to grasp the state.

When the passenger dismounts, the engine sound continues to be output as long as the main switch MS is turned on.
It is also possible to prevent forgetting to turn off the main switch MS.

On the other hand, when the driver operates the throttle grip 13 while the electric motorcycle 1 is stopped, the electric motor is driven to start traveling.

Then, based on the speed detection signal from the speed sensor 9 and the voltage level signal from the voltage sensor 6, the control device S reads the sound data corresponding to the state from the memory map of the ROM 14. And outputs it to the sound emitting device 12A.

As a result, the output sound quality and volume change according to the change in speed and the exhaustion state of the battery 3, so that the driver can also perceive the running state and the exhaustion state of the battery during running. Becomes

In particular, when a sound imitating the engine sound in which the number of revolutions increases is output as the running speed increases, a running feeling similar to that of a motorcycle equipped with an engine can be obtained. it can.

When the volume is gradually decreased as the traveling speed increases, the state of the electric motor cycle 1 is clearly notified with a large volume in the stopped state, and in the traveling state. It is possible to give a notification at a low volume so as not to hinder driving.

Further, in the present embodiment, the case where a sound imitating the engine sound is output from the sounding device 12A has been described, but the present invention is not limited to this, and the sound quality that can inform the driver of the state of the electric motorcycle 1 is provided. Anything will do.

The sounding device (speaker) 12A is
The present invention is not limited to the case where it is provided on the side surface of the cowl 11 below the seat 10 as in the present embodiment, but may be provided, for example, on the front cover portion 5 or the like, or at a position where the driver can hear the sound. You can place it anywhere you want.

Further, the sound output device 12A is not limited to the case where it is constituted by a speaker, and may be a buzzer or the like.

Next, with reference to FIG. 4 and FIG. 5, a structural example of the vibration generator 12B as the second embodiment of the present invention will be explained.

FIG. 4 is a side sectional view of the vibration generator 12B, and FIG. 5 is a sectional view taken along the line AA.

In this embodiment, the vibration generator 12B, which is the notification means 12, is incorporated in the throttle grip 13.

In the figure, 20 is a handlebar made of a metal pipe, and a non-slip grip rubber 2 is provided on the outer periphery thereof.
1 is provided.

An electric motor 23 is arranged in the handlebar 20 via a motor support member 22.

An eccentric metal or resin weight 25 is fixed to a rotary shaft 24 of the electric motor 23, and the other end of the rotary shaft 24 is supported by a bearing member 26.

The electric motor 23 is connected to the control device S.

Then, the electric motor 23 rotates based on the drive signal from the control device S to rotate the eccentric weight 25.

As a result, the throttle grip 13 is vibrated in accordance with the rotational speed of the eccentric weight 25.

Although not shown, the drive data of the vibration generator 12B in which the voltage level and the speed of the battery 3 are correlated with each other in a predetermined storage area in the ROM 14 as in the memory map of FIG. Is stored in a memory map, and the vibration generator 12 is stored in accordance with the memory map.
The vibration state of B can be changed.

Now, the operation of the electric motorcycle 1 provided with the vibration generator 12B having the above-described structure will be described.

First, as in the case of the first embodiment, when the driver operates the main switch MS to turn it on from the state in which the start key is inserted, the control device S, the voltage sensor 6, and the speed are set. The sensor 9 and the like start operating.

Then, the speed sensor 9 outputs, for example, a signal indicating a stopped state in which the electric motorcycle 1 can start, and the voltage sensor 6 outputs, for example, the battery 3
When a detection signal indicating that the voltage level of R is high is output to the control device S, the control device S causes the R
The drive data corresponding to the state is read from the memory map of the predetermined storage area of the OM 14, and the electric motor 2 is read.
3 is rotated at a predetermined rotation speed.

As a result, the eccentric weight 25 rotates and vibration is generated in the throttle grip 13, and the driver can start the electric motorcycle 1, and the voltage of the battery 3 is sufficient. Since it is possible to experience through tactile sensation that the speed is extremely high, it is possible to take care not to perform a sudden throttle operation.

If the memory map of the drive data is constructed so that the rotation speed of the electric motor 23 gradually decreases as the voltage of the battery 3 decreases,
Since the vibration also gradually decreases, the player can grasp the consumption state of the battery 3 through the sense of touch.

Further, at the time of getting off, vibration continues to be generated as long as the main switch MS is turned on, so that it is possible to prevent forgetting to turn off the main switch MS.

In this embodiment, the case where the vibration generating device 12B is incorporated only in the throttle grip 13 has been described, but the same vibration generating device 1 is used in the grip on the opposite side.
2B may be incorporated so that vibration can be felt with both hands.

A vibration generator 12B of the same principle is also used.
May be provided in the seat 10, the step portion 2, or the like.

Further, as the vibration generator, in addition to the mechanical vibration generator shown in this embodiment, for example, a pulse voltage may be applied to a piezoelectric element or the like to generate the vibration.

Further, as shown in FIG. 1, both the sounding device 12A and the vibration generating device 12B can be provided as the informing means 12, and in this case, it is more reliable via both hearing and tactile sense. In addition, the state of the electric motorcycle 1 can be perceived by experience.

Further, the notifying means 12 is not limited to the sound emitting device 12A and the vibration generating device 12B shown in the present embodiment, and a lamp, an LED or the like is turned on in accordance with the state of the electric motor cycle 1 to visually. It is also possible to have a configuration capable of notifying.

Although the present invention relates to an electric motorcycle, the same effect can be obtained by applying the present invention to a four-wheel electric vehicle.
