Data Recorders of Autonomous Vehicles - A simplified explanation of the abstract
This abstract first appeared for US patent application 18326972 titled 'Data Recorders of Autonomous Vehicles
Simplified Explanation
- This patent application describes a system for collecting sensor data in an autonomous vehicle. - The vehicle's sensors generate a continuous stream of data, which is stored in two separate cyclic buffers. - The first cyclic buffer stores a smaller segment of the data, while the second cyclic buffer stores a larger segment. - The vehicle's advanced driver assistance system can detect or predict accidents and faults in object detection. - When an accident is detected, a segment of the sensor data stream is copied from the first cyclic buffer to a non-volatile memory slot. - The non-volatile memory has multiple slots, and the copied segment is placed in a slot selected in a round-robin manner. - When a fault in object detection is detected, a segment of the sensor data stream is copied from the second cyclic buffer to a different area of the non-volatile memory. - This different area is outside of the slots reserved for the first cyclic buffer.
Original Abstract Submitted
Systems, methods and apparatus to collect sensor data generated in an autonomous vehicle. Sensors of the vehicle generate a sensor data stream that is buffered, in parallel and in a cyclic way, in a first cyclic buffer and a larger second cyclic buffer respectively. An advanced driver assistance system of the vehicle generates an accident signal when detecting or predicting an accident and provides a training signal when detecting a fault in object detection, recognition, identification or classification. The accident signal causes a sensor data stream segment to be copied from the first cyclic buffer into a slot of a non-volatile memory, selected from a plurality of slots in a round robin way. The training signal causes a sensor data stream segment to be copied from the second cyclic buffer into an area of the non-volatile memory outside of the slots reserved for the first cyclic buffer.
