Abstract: Data is received regarding vehicle braking events, each event occurring on one of a plurality of vehicles, and each event associated with a location. A determination is made that the braking events correspond to a pattern. Based on determining that the braking events correspond to the pattern, a first location is identified. In response to identifying the first location, at least one action is performed.

Abstract: A map in a cloud service stores physical objects previously detected by other vehicles that have previously traveled over the same road that a current vehicle is presently traveling on. New data received by the cloud service from the current vehicle regarding new objects that are being encountered by the current vehicle can be compared to the previous object data stored in the map. Based on this comparison, an operating status of the current vehicle is determined. In response to determining the status, an action such as terminating an autonomous navigation mode of the current vehicle is performed.

The disclosed embodiments utilize a one-time programmable (OTP) memory added to both a memory device and a processing device. The OTP memory stores encryption keys and the encryption and decryption of messages between the two devices are used as a heartbeat to determine that the memory device has not been separated from the processing device and, in some instances, connected to a malicious processing device.

Abstract: A system includes a memory device and a processing device coupled to the memory device. The processing device can determine a data rate from a first sensor and a data rate from a second sensor. The processing device can write a first set of data received from the first sensor at a first logical block address (LBA) in the memory device. The processing device can write a second set of data received from the second sensor and subsequent to the first set of data at a second LBA in the memory device. The processing device can remap the first LBA and the second LBA to be logically sequential LBAs. The second LBA can be associated with an offset from the first LBA and the offset can correspond to a data rate of the first sensor.

Abstract: Systems, methods, and apparatus related to dynamically adjusting sensing and/or processing resources of a vehicle. In one approach, sensor data is collected by sensing devices of the vehicle. A controller of the vehicle uses the sensor data to control one or more functions of the vehicle. The controller evaluates the sensor data to determine a context of operation (e.g., weather, lighting, and/or traffic) for the vehicle. Based on the context of operation, the controller adjusts the operation of one or more of the sensing or processing devices in real-time during operation of the vehicle. In one example, the adjustment reduces power consumption by the vehicle.

Abstract: Systems, methods, and apparatus related to data storage devices. In one approach, a string of storage devices are chained together and coupled to a host device for storing data. Each storage device may, for example, execute read, write, or erase commands received from the host device. Each storage device in the chain is a master to the next storage device in the chain, and each storage device is a slave to the previous storage device in the chain. In one example, the host device is a system-on-chip. The chain can manage itself and is seen as a single large storage space to the host device. The host device does not require knowledge about each individual storage device, and each storage device does not require knowledge about the other storage devices in the chain (other than whether the storage device is attached to another storage device on its master port).

Abstract: 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.

Abstract: An improved black box data recorder for use with autonomous driving vehicles (AVD). In one embodiment, two cyclic buffers are provided to record vehicle sensors data. A first cyclic buffer records raw vehicle sensor data on a volatile memory, while a second cyclic buffer records the same vehicle sensor data, as compressed data, on a non-volatile memory. In a case of a collision or near collision, in one embodiment the buffers are flushed into a non-volatile (NV) storage for retrieval. As long as there is no power interruption, the raw vehicle sensor data will be accessible from the NV storage. If a power interruption occurs, the raw vehicle sensor data held in the volatile memory of the first cyclic buffer will be lost and only the compressed form of the vehicle sensor data from the second cyclic buffer will survive and be accessible.

Abstract: Systems, methods, and apparatus related to determining ice hazards on roads based on crowdsourced data from vehicles. In one approach, a server receives weather data and location data from each of several vehicles. The weather data is timestamped when received. The server determines, using the location data, a geographic region in which each vehicle is located. The weather data is stored in a database associated with the respective geographic region for the vehicle that transmitted the weather data. The server periodically scans the database to select weather data received over a selected time period. The selected data is analyzed to determine whether an ice hazard exists for one or more regions. A communication is sent to vehicles in those regions having the determined ice hazard.
