Vehicle integrated control device and vehicle integrated control method
Provided is a vehicle integrated control device capable of controlling a posture of a vehicle so as to prevent in advance an occupant who has high sensitivity to motion sickness from suffering from the motion sickness. The vehicle integrated control device includes a target value generation unit that generates or acquires a control target value of a movement of a vehicle; a motion sickness sensitivity acquisition unit that acquires a motion sickness sensitivity index that is a quantitative value that is likeliness of incidence of motion sickness that differs depending on an occupant characteristic with respect to at least one occupant riding on the vehicle; and a target value correction unit that corrects the control target value based on the control target value and the motion sickness sensitivity index.
1 . A vehicle integrated control device comprising a processor configured to:
generate or acquire a control target value of a movement of a vehicle, a present vehicle movement of the vehicle, and a first head movement of an occupant of the vehicle;
acquire a feature of the first head movement that differs depending on an occupant characteristic of the occupant from the present vehicle movement and the first head movement;
predict a second head movement of the occupant attributed to the control target value based on the acquired feature of the first head movement;
acquire a motion sickness sensitivity index that is a quantitative value indicating a likelihood of incidence of motion sickness that differs depending on the occupant characteristic of the occupant, wherein the likelihood is predicted based on the present vehicle movement and the second head movement; and
correct the control target value based on the control target value and the motion sickness sensitivity index.
2 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
acquire, as the occupant characteristic, at least one of a vehicle riding position of the occupant, a riding direction, line-of-sight information, posture of a head, a motion sickness incidence rate, or a past motion sickness incidence history.
3 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
receive an input of the motion sickness sensitivity index to acquire the likelihood of incidence of motion sickness.
4 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
predict, as the motion sickness sensitivity index, the likelihood of incidence based on a past degree of incidence of motion sickness of the occupant.
5 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
correct the control target value such that the larger the motion sickness sensitivity index, the larger a correction width of the control target value becomes.
6 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
correct the control target value such that the motion sickness sensitivity index falls within a predetermined value.
7 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
correct the control target value such that the larger a change in a posture of the head of the occupant with respect to the control target value, the larger a correction width of the control target value becomes.
8 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
correct the control target value such that a change in a posture of the head of the occupant with respect to the control target value falls within a predetermined value.
9 . The vehicle integrated control device according to claim 1 , wherein the processor is further configured to:
determine manipulated variables of a plurality of actuators mounted on the vehicle such that a controlled value approaches the control target value.
10 . The vehicle integrated control device according to claim 9 , wherein the processor is further configured to:
correct the control target value such that the larger the motion sickness sensitivity index, the larger the manipulated variables of the actuators become.
11 . A vehicle integrated control method comprising:
generating or acquiring a control target value of a movement of a vehicle, a present vehicle movement of the vehicle, and a first head movement of an occupant of the vehicle;
acquiring a feature of the first head movement that differs depending on an occupant characteristic of the occupant from the present vehicle movement and the first head movement;
predicting a second head movement of the occupant attributed to the control target value based on the acquired feature of the first head movement;
acquiring a motion sickness sensitivity index that is a quantitative value indicating a likelihood of incidence of motion sickness that differs depending on the occupant characteristic of the occupant, wherein the likelihood is predicted based on the present vehicle movement and the second head movement; and
correcting the control target value based on the control target value and the motion sickness sensitivity index.
12 . The vehicle integrated control method according to claim 11 , further comprising:
acquiring, as the occupant characteristic, at least one of a vehicle riding position, a riding direction, line-of-sight information, posture of a head, a motion sickness incidence, or a past motion sickness incidence history of the occupant.
13 . The vehicle integrated control method according to claim 11 , further comprising:
receiving an input of the motion sickness sensitivity index to acquire the likelihood of incidence of motion sickness.
