Automatic driving assistance device and automatic driving assistance method
An automatic driving assistance device includes an information acquirer configured to acquire information on a state of a cabin of a vehicle capable of automatic driving and a modifier configured to modify traveling characteristics in automatic driving according to the state of the cabin of the vehicle.
1. An automatic driving assistance device comprising:
an information acquirer configured to acquire information on a state of a cabin of a vehicle capable of automatic driving; and
a modifier configured to modify traveling characteristics in automatic driving according to the state of the cabin of the vehicle,
wherein the modifier modifies a parameter corresponding to an amount of operation that is varied by a driving operation by a driver in manual driving.
2. The automatic driving assistance device according to claim 1 , wherein the modifier modifies the parameter according to a load capacity of the vehicle that is estimated from the information acquired by the information acquirer.
3. The automatic driving assistance device according to claim 1 , wherein the modifier modifies an automatic driving operation characteristic that is a time-series variation pattern of the parameter.
4. The automatic driving assistance device according to claim 1 , wherein the information acquirer acquires a taken image acquired by a camera that takes an image of the cabin of the vehicle.
5. The automatic driving assistance device according to claim 1 , wherein the information acquirer acquires information transmitted from a vehicle-mounted device mounted on the vehicle.
6. The automatic driving assistance device according to claim 1 , wherein
the vehicle is an electric vehicle or a hybrid vehicle provided with a traveling sound generating device, and
the modifier modifies at least sound volume or sound quality of traveling sound generated by the traveling sound generating device.
7. The automatic driving assistance device according to claim 1 , wherein
the vehicle is a hybrid vehicle, and
the modifier modifies a distribution ratio between electric driving and engine driving.
8. The automatic driving assistance device according to claim 1 , wherein
the vehicle is provided with a navigation device; and
the modifier modifies a navigation route presented by the navigation device according to the state of the cabin of the vehicle.
9. An automatic driving assistance method, comprising:
an information acquiring step of acquiring information on a state of a cabin of a vehicle capable of automatic driving; and
a modifying step of modifying traveling characteristics in automatic driving according to the state of the cabin of the vehicle,
wherein, in the modifying step, a parameter corresponding to an amount of operation that is varied by a driving operation by a driver in manual driving is modified.
