Information transmission method implemented in vehicle and information transmission system for motorcycle

1. An information transmission method implemented in a vehicle to transmit information to a driver of the vehicle, the vehicle being equipped with a display device disposed to be viewable by the driver assuming a driving posture, the method comprising:

determining a type of the information to be transmitted to the driver when the driver is driving the vehicle;

outputting the information in the form of sound; and

operating the display device to display an illumination pattern as a function of the determined type, wherein

the type is selected from a plurality of information types including a response status associated with information generated in communication with the driver, and

the illumination pattern displayed by the display device is varied based on whether the determined type is the response status.

2. The information transmission method according to claim 1 , wherein

the response status includes a standby status where a question from the driver is waited for, an analyzing status intermediate between receiving the question from the driver and giving an answer to the question, and an answering status where the answer to the question is being given, and

when the determined type is the response status, the illumination pattern displayed by the display device is varied based on whether the response status is the standby status, the analyzing status, or the answering status.

3. The information transmission method according to claim 1 , further comprising outputting the information to be transmitted to the driver in the form of sound, wherein

the type is selected from a plurality of information types including an event notification status associated with information generated based on an event other than communication with the driver,

when the determine type is the event notification status, event information is output in the form of sound, and

the illumination pattern displayed by the display device is varied based on whether the determined type is the event notification status.

4. An information transmission system for a motorcycle, comprising:

a sound output device that outputs sounds;

a display device mounted on a body of the motorcycle and disposed to be viewable by a driver assuming a driving posture; and

a control device that controls the sound output device and the display device,

the control device being configured to:

determine a type of information to be transmitted to the driver when the driver is driving the motorcycle;

operate the sound output device to output the information to be transmitted; and

operate the display device to display an illumination pattern as a function of the determined type, wherein

the type is selected from a plurality of information types including a response status associated with information generated in communication with the driver, and

the illumination pattern displayed by the display device is varied based on whether the determined type is the response status.

5. The information transmission system according to claim 4 , wherein the display device comprises a side light unit located outward of an instrument unit displaying a state of the motorcycle in a width direction of the motorcycle.

6. The information transmission system according to claim 5 , wherein the side light unit comprises a pair of light units located outward of the instrument unit in the width direction of the motorcycle.

7. The information transmission system according to claim 5 , wherein the display device changes the illumination pattern by changing at least one of color, blinking rate, and order of turning on.

8. The information transmission system according to claim 4 , wherein

the response status includes a standby status where a question from the driver is waited for, an analyzing status intermediate between receiving the question from the driver and giving an answer to the question, and an answering status where the answer to the question is being given, and

when the determined type is the response status, the illumination pattern displayed by the display device is varied based on whether the response status is the standby status, the analyzing status, or the answering status.

9. An information transmission method implemented in a vehicle to transmit information to a driver of the vehicle, the vehicle being equipped with a display device disposed to be viewable by the driver assuming a driving posture, the method comprising:

determining a type of the information to be transmitted to the driver when the driver is driving the vehicle based on a determination between a first information type and a second information type;

outputting the information in the form of sound; and

operating the display device to display an illumination pattern as a function of the determined type, wherein

the first information type is selected from a plurality of information types including a response status associated with information generated in communication with the driver, and the illumination pattern displayed by the display device is varied based on whether the determined type is the response status; and

the second information type is selected from a plurality of information types including an event notification status associated with information generated based on an event other than communication with the driver, the event includes at least one of nearby traffic information, weather information, route navigation information, traffic information, and warning information indicating that another vehicle is approaching, when the determined type is the event notification status, event information is output in the form of sound, and the illumination pattern displayed by the display device is varied based on whether the determined type is the event notification status.
