The invention relates to the technical field of positioning, particularly provides a vehicle-mounted UWB positioning system and a vehicle, and aims to solve the problem that the positioning range of the existing vehicle-mounted UWB positioning technology is limited. In order to achieve the purpose, a UWB node in the vehicle-mounted UWB positioning system comprises three antenna subunits, the first antenna subunit and the second antenna subunit are combined to test the horizontal azimuth angle of a to-be-tested target through the AOA technology, and the first antenna subunit and the third antenna subunit are combined to test the vertical pitch angle of the to-be-tested target through the AOA technology. And one of the three antenna subunits can test the distance of the target to be tested by using the TOF technology. One UWB node in the vehicle-mounted UWB positioning system can obtain the horizontal azimuth angle, the vertical pitch angle and the distance of the to-be-measured target at the same time, the to-be-measured target can be accurately positioned through the horizontal azimuth angle, the vertical pitch angle and the distance of the to-be-measured target, and the distance measurement and positioning range of the vehicle-mounted UWB positioning system is greatly enlarged.
本发明涉及定位技术领域,具体提供一种车载UWB定位系统及车辆,旨在解决现有的车载UWB定位技术存在定位范围限制的问题。为此目的,本发明中的车载UWB定位系统中的UWB节点包括三个天线子单元,第一天线子单元和第二天线子单元组合利用AOA技术测试待测目标的水平方位角,第一天线子单元和第三天线子单元组合利用AOA技术测试待测目标的竖直俯仰角,且三个天线子单元中的其中一个能够利用TOF技术测试待测目标的距离。车载UWB定位系统中的一个UWB节点就能够同时获得待测目标的水平方位角、竖直俯仰角以及距离,而通过待测目标的水平方位角、竖直俯仰角以及距离就能够对待测目标进行准确定位,大大增加了车载UWB定位系统的测距和定位范围。
