The invention discloses an anti-collision method of an unmanned vehicle, a vehicle-mounted device and an anti-collision system, and relates to the technical field of unmanned driving of surface mines. The method comprises the steps: obtaining a vehicle information table, wherein the vehicle information table at least comprises a vehicle identifier and an anti-collision safety circle corresponding to the vehicle identifier; determining a first dynamic anti-collision safety circle of the vehicle and a second dynamic anti-collision safety circle of the surrounding vehicle according to the first current speed of the vehicle, the second current speed of the surrounding vehicle and the vehicle information table; and controling the vehicle to execute corresponding operation by judging the intersection state of the first dynamic anti-collision safety circle of the vehicle and the second dynamic anti-collision safety circle of the surrounding vehicle. By means of the technical scheme, the reasonable driving distance between the vehicle and the surrounding vehicle can be kept during vehicle meeting, meanwhile, the calculation amount is greatly reduced, so that the calculation speed is increased, and the timeliness of vehicle anti-collision operation execution is guaranteed.
本申请公开了无人驾驶车辆的防碰撞方法、车载装置及防碰撞系统,涉及露天矿山无人驾驶技术领域。其中方法包括:获取车辆信息表,所述车辆信息表至少包括车辆标识和与所述车辆标识相对应的防碰撞安全圈;根据本车的第一当前速度和周边车辆的第二当前速度,以及所述车辆信息表,确定本车的第一动态防碰撞安全圈和周边车辆的第二动态防碰撞安全圈;通过判断本车的第一动态防碰撞安全圈与周边车辆的第二动态防碰撞安全圈的相交状态,控制本车执行相应操作。通过本申请的技术方案,能够在会车时,与周边车辆保持合理的行驶间距,同时极大程度地降低计算量,提升计算速度,保证车辆防碰撞操作执行的及时性。
