The invention discloses a vehicle 3D positioning method with privacy protection based on V2R or V2V communication in a vehicle-mounted network, comprising the steps of global setting, registering, establishing a safety channel and position proving. The invention can only realize 2D positioning for most of the existing vehicle positioning systems, which can not achieve accurate 3D positioning and vehicle privacy protection. a vehicle 3D location method with privacy protection based on V2R communication and V2V communication respectively is proposed, which enables a vehicle with unknown 3D position to obtain 3D position efficiently and accurately with the help of roadside unit or vehicle with known 3D position under the premise of protecting privacy. 本发明公开了种车载网中基于V2R或V2V通信的具有隐私保护的车辆3D定位方法，包括：全局设置、注册、建立安全信道、位置证明步骤。本发明针对现有的多数车载定位系统只能实现2D定位，无法实现准确的3D定位以及车辆隐私保护等问题，提出了分别基于V2R通信和基于V2V通信的具有隐私保护的车辆3D定位方法，使得辆未知3D位置的车辆借助路边单元或者已知3D位置的车辆在保护隐私的前提下高效的、准确的获取3D位置。
