IPC: B60W40/107
Filed: 2020-02-10
Abstract: To provide a vehicle seat that reduces occupant sickness by reducing an acceleration generated by the occupant.SOLUTION: From an image pickup information including a travel path information acquired by an image pickup camera, a predicted acceleration change amount, which is a change amount of an acceleration generated by a control unit on an occupant, is calculated (step S120). When it is determined that the amount is within a predetermined sickness determination threshold range (step S130), a seating surface on which the occupant is seated is tilted to cause the occupant to accelerate by controlling a rotation speed of a motor. At this time, by inclining the seat surface at a speed and direction in which the change amount of the acceleration decreases, the change amount of the acceleration felt by the occupant is reduced to a range that is not included in the predetermined sickness determination threshold range. As a result, a possibility of occupant sickness can be reduced.SELECTED DRAWING: Figure 4
