Vehicle information presenting device
A vehicle information presenting device used for an automated driving vehicle that automatically performs traveling control of the vehicle based on a traveling state of the vehicle and information on an outside of the vehicle includes: a steering wheel; a light-emitting unit that is disposed in the steering wheel and emits light; and a light-emitting control unit that causes the light-emitting unit to emit light, wherein the light-emitting control unit changes a light-emitting state of the light-emitting unit to induce a driver to switch from automated driving to manual driving in accordance with a system state of the automated driving.
1. A vehicle information presenting device used for an automated driving vehicle that automatically performs traveling control of the vehicle based on a traveling state of the vehicle and information on an outside of the vehicle, comprising:
a steering wheel;
a light-emitting unit that is disposed in the steering wheel and emits light; and
a light-emitting control unit that causes the light-emitting unit to emit light, wherein
the light-emitting control unit changes a light-emitting state of the light-emitting unit to induce a driver to switch from automated driving to manual driving in accordance with a system state of the automated driving, and causes each of gripping positions separated on left and right of an upper side of the steering wheel to emit light for indicating positions of the steering wheel to be gripped with left and right hands to the driver, and
the light-emitting control unit does not cause an upper portion of the gripping positions to emit light,
wherein when the steering wheel is turned by the automated driving, the light-emitting control unit causes the gripping positions that are appropriate for a manual driving operation to emit light.
2. The vehicle information presenting device according to claim 1 , wherein the light-emitting control unit categorizes the system state into areas and causes the light-emitting unit to emit light in accordance with a categorized system state.
3. The vehicle information presenting device according to claim 1 , wherein the light-emitting control unit causes the light-emitting unit to emit light such that the light-emitting of the light-emitting unit is formed in a shape of a hand.
4. The vehicle information presenting device according to claim 1 , wherein the light-emitting control unit enlarges a light-emitting region of the light-emitting unit as the system state becomes more unstable, and causes the light-emitting unit to emit light such that the light-emitting of the light-emitting unit is formed in a shape of a hand when the system state is categorized as a most unstable area.
5. The vehicle information presenting device according to claim 1 , wherein the light-emitting control unit changes at least one of brightness and a color of the light in accordance with the system state.
6. The vehicle information presenting device according to claim 1 , wherein the light-emitting control unit alternates light-emitting regions of the steering wheel.
