Autonomous driving simulation using recorded driving data is disclosed. A method of simulating autonomous driving includes receiving recorded driving data from a recorded autonomous vehicle (AV), therecorded driving data includes decision-making data generated using a first decision-making algorithm, sensing data, and movement data including positions of the recorded AV; obtaining simulation datafrom the recorded driving data by excluding the decision-making data from the recorded driving data; and simulating, by a simulation AV, a second decision-making algorithm using the simulation data.The simulating the second decision-making algorithm includes determining a first position of the simulation AV at a first time and adjusting a playback speed of the simulation data based on a difference between the first position and a second position of the positions of the recorded AV at the first time.
公开了使用记录驾驶数据的自主驾驶模拟。模拟自主驾驶的方法包括:从记录自主运载工具(AV)接收记录驾驶数据,该记录驾驶数据包括:使用第一决策算法生成的决策数据、感测数据、以及包括记录AV的位置的移动数据;通过从记录驾驶数据中排除决策数据来从记录驾驶数据获得模拟数据;以及由模拟AV使用模拟数据来模拟第二决策算法。模拟第二决策算法包括:确定模拟AV在第一时间的第一位置;以及基于第一位置和记录AV的位置中的在第一时间的第二位置之间的差来调整模拟数据的重放速率。
