Systems, methods and apparatus to collect sensor data generated in an autonomous vehicle. Sensors in the vehicle generate a sensor data stream during operations of the vehicle on a road. An advanced driver assistance system (ADAS) of the vehicle uses the sensor data stream to operate the vehicle and generate a trigger signal in response to a fault in object detection, recognition, identification or classification and/or in response to the detection/prediction of an accident. A cyclic buffer buffers at least a portion of the sensor data stream. In response to the trigger signal, a selected segment of the sensor data stream is stored into a non-volatile memory. The selected segment can be partially before the trigger signal and partially after the trigger signal; and selected segment can be longer than what can be fully buffered in the cyclic buffer at the time of the trigger signal.
用于收集在自主车辆中生成的传感器数据的系统、方法和设备。所述车辆中的传感器在所述车辆在道路上操作期间生成传感器数据流。所述车辆的高级驾驶员辅助系统(ADAS)使用所述传感器数据流来操作所述车辆并响应于对象检测、识别、标识或分类中的故障和/或响应于事故的检测/预测而生成触发信号。循环缓冲器缓冲所述传感器数据流的至少一部分。响应于所述触发信号,所述传感器数据流的选择段被存储到非易失性存储器中。所述选择段可以部分在所述触发信号之前,部分在所述触发信号之后;并且选择段可以长于可以在所述触发信号时完全缓冲在所述循环缓冲器中的段。
