The invention provides a traffic-light-free intersection multi-mine-car passing strategy method and system, and the method comprises the steps: 1, building a conflict table based on a conflict point model, and constructing a virtual signal light phase combination; 2, controlling the phase of the virtual signal lamp based on deep reinforcement learning; and step 3, constructing a mine car safety braking distance model based on the braking distance of the self car, the braking distance of the front car and the distance between the two cars after complete braking, and adjusting the speed of the mine car based on the safety braking distance model. According to the invention, safe mixed passing of the unmanned mine car and the manned mine car in the scene of the irregular intersection without the signal lamp is realized, and the passing efficiency is effectively improved.

    本发明提供了一种无信号灯交叉路口多矿车通行策略方法和系统,包括:步骤1:基于冲突点模型,建立冲突表,构建虚拟信号灯相位组合;步骤2:基于深度强化学习,控制虚拟信号灯相位;步骤3:基于自车的制动距离、前车的制动距离和两车完全制动后的间距,构建矿车安全制动距离模型,并基于安全制动距离模型调整矿车速度。本发明实现了无人驾驶矿车与有人驾驶矿车在无信号灯不规则交叉路口场景下安全混合通行,并有效地提高了通行效率。
