一种车载导航仪及其控制方法

Vehicle-mounted navigator and control method thereof

Abstract

本发明公开了一种车载导航仪及其控制方法,涉及导航技术领域,可以顾及车内所有人员观看显示屏的观看视角,全面提升了每个人员的行车体验。具体方案为:车载导航仪包括导航仪主机和显示屏,显示屏上连接有带动显示屏沿水平方向、垂直方向旋转的轴部件;导航仪主机获取车内座椅的高度数据和车内人员的身高数据;根据获取的车内座椅的高度数据和车内人员的身高数据,分别计算车内至少两个人员中每个人员的眼部位置到显示屏的中心点的连线与显示屏所在平面的夹角;根据计算模块计算得到的夹角,通过步进电机控制轴部件带动显示屏沿水平方向和垂直方向旋转,以使至少两个人员中每个人员的眼部位置到显示屏的中心点的连线与显示屏所在平面的夹角相等。
The present invention discloses a vehicle-mounted navigator and a control method thereof, and relates to the technical field of navigation, wherein the display screen viewing angles of all people in a vehicle can be considered so as to completely improve the driving experience of each person. The concrete technical scheme comprises that the vehicle-mounted navigator comprises a navigator host machine and a display screen, wherein the display screen is connected to a shaft part for driving the display screen to rotate along a horizontal direction and a vertical rotation. The control method comprises that the navigator host machine acquires the height data of the seats in a vehicle and the body height data of people in the vehicle; according to the acquired height data of the seats in the vehicle and the body height data of the people in the vehicle, the included angles between the connection line from the eye position to the center point of the display screen and the plane of the display screen of at least people in the vehicle are respectively calculated; and according to the included angles calculated by a calculation module, the shaft part is controlled by a stepping motor to drive the display screen to rotate along a horizontal direction and a vertical rotation, such that the included angles between the connection line from the eye position to the center point of the display screen and the plane of the display screen of the two people are equal to each other.
