The present invention relates to a method for reducing morning sickness, which predicts a motion of a vehicle causing morning sickness while the vehicle drives along a target path to transmit the predicted motion to a passenger, and at the same time, preforms reduction control. The method comprises: a prediction step of predicting and calculating the motion according to a behavior of the vehicle while the vehicle drives along the target path; a display step of displaying the motion of the vehicle calculated in the prediction step in a hologram to have a size and a direction in a coordinate system; a comparison step of comparing the size of the motion of the vehicle with a preset limit size; a reduction amount calculation step of calculating a reduction amount required for restraining the motion of the vehicle as much as an exceeding amount in an exceeding section where the size of the motion of the vehicle is predicted to exceed the limit size; and a speed gain calculation step of determining a reduction gradient of the vehicle to be controlled to reduce speed at a t time point before arriving the exceeding section according to the reduction amount in the exceeding section to calculate a speed gain to be calculated with reference speed of the vehicle.

    본 발명은 차량이 목표 경로를 따라 주행 중에 멀미를 유발할 수 있는 차량의 움직임을 미리 예측하여 탑승자에게 전달함과 동시에 감속 제어를 수행할 수 있는 멀미 저감 방법에 관한 것으로, 목표 경로를 주행하는 동안 차량의 거동에 따른 움직임을 예측하여 연산하는 예측단계; 상기 예측단계에서 연산된 차량의 움직임을 좌표계 내에서 크기와 방향을 갖도록 홀로그램으로 표시하는 표시단계; 상기 차량의 움직임의 크기와 미리 설정된 Limit 크기를 비교하는 비교단계; 상기 차량의 움직임의 크기가 상기 Limit 크기를 초과하는 것으로 예측되는 초과구간에서 그 초과량만큼 차량의 움직임을 제한하는데 필요한 감속량을 연산하는 감속량 연산단계; 및 상기 초과구간에서 상기 감속량에 따라 상기 초과구간 이전 t 시점에서 감속 제어 되도록 차량의 감속 기울기를 결정하여 차량의 기존 속도와 연산될 수 있도록 속도게인을 연산하는 속도게인 연산단계;를 포함한다.
