| 发明名称 | Vehicle suspension device | ||
| 摘要 | A vehicle suspension device includes a suspension device main body configured to support a wheel of a vehicle to a vehicle body of the vehicle; a varying device configured to cause an upper connecting portion stiffness and a lower connecting portion stiffness to be variable, the upper connecting portion stiffness being a stiffness between a vertically upper portion of the suspension device main body and the vehicle body, and the lower connecting portion stiffness being a stiffness between a vertically lower portion of the suspension device main body and the vehicle body; and a control device configured to control the varying device at a time of braking of the vehicle to perform control which causes the upper connecting portion stiffness to be relatively decreased and causes the lower connecting portion stiffness to be relatively increased, compared to at a time of non-braking of the vehicle. | ||

| 主权项 | 1. A vehicle suspension device comprising: a suspension device main body configured to support a wheel of a vehicle to a vehicle body of the vehicle; a varying device configured to cause an upper connecting portion stiffness and a lower connecting portion stiffness to be variable, the upper connecting portion stiffness being a stiffness between a vertically upper portion of the suspension device main body and the vehicle body, and the lower connecting portion stiffness being a stiffness between a vertically lower portion of the suspension device main body and the vehicle body; and a control device configured to control the varying device at a time of braking of the vehicle to perform control which causes the upper connecting portion stiffness to be relatively decreased and causes the lower connecting portion stiffness to be relatively increased, compared to at a time of non-braking of the vehicle, wherein the control device changes the upper connecting portion stiffness and the lower connecting portion stiffness so that a front-back force compliance of a spindle of the wheel at the time of braking of the vehicle is equal to a front-back force compliance of the spindle at the time of non-braking of the vehicle. | ||
