A method for detecting abnormal operating states of a device includes obtaining model data to the device that is representative of operating states to be expected for at least one component of the device. The device collects measurement data that is representative of an actual operating state of the component of the device. The device ascertains comparison data on the basis of the model data and the measurement data, where the comparison data is representative of an expected operating state. The method includes using the comparison data and the measurement data as a basis for determining whether there is a discrepancy between the actual operating state and the expected operating state. The method further includes attributing an abnormal operating state to the at least one component in a manner corresponding to a time of collection of the measurement data on the basis of the discrepancy.

A driving data collection method is disclosed, including: obtaining driving scenario requirement information (S203); determining at least one sensor on a vehicle based on the driving scenario requirement information (S204); and then, sending driving data collected by the at least one sensor to a network side device (S206).

A system for controlling the locking of accessories by a vehicle includes a vehicle door, a door lock, and an input device configured to receive user input including an unlock request. The system further includes an accessory lock configured to alternate between a locked accessory state and an unlocked accessory state. The system further includes a network access device. The system further includes an ECU designed to determine a door unlock event in response to the input device receiving the unlock request and to control the door lock to alternate from the locked door state to the unlocked door state in response to determining the door unlock event. The ECU is further designed to control the network access device to instruct the accessory lock to alternate from the locked accessory state to the unlocked accessory state in response to determining the door unlock event.

The present disclosure provides methods and systems for identifying or verifying trip information. A method for identifying or verifying a trip of a vehicle comprises detecting a presence of the vehicle with a mobile computing device of a user. The mobile computing device may be removable from the vehicle. Next, a trip start may be determined when the vehicle is detected by the mobile computing device as being present. Trip data may be recorded for a trip of the vehicle subsequent to the trip start, the trip data being based at least in part on sensor readings. A trip end that corresponds to an end of the trip of the vehicle may be detected and verified.

A recording system for a vehicle according to an example of the present disclosure includes proximity sensors configured to obtain data indicative of a distance between a vehicle and external objects and at least one vehicle operation sensor configured to obtain data indicative of how a driver is operating the vehicle. A controller is configured to obtain input data for a current monitoring period that includes data from the plurality of proximity sensors and the at least one vehicle operation sensor; utilize a predictive engine to determine whether the input data fulfills a criteria set corresponding to a potential impending vehicle incident; based on the input data fulfilling the criteria set commence saving of the input data from the current monitoring period and subsequent monitoring periods in a data set; and based on the input data not fulfilling the criteria set delete the input data for the current monitoring period.

Disclosed are systems and methods relating to providing intersection metrics based on road network data and telematic data.

The disclosure relates generally to an in-vehicle feedback system, and more particularly, to an in-vehicle device with a display or graphical interface that collects driving data and provides feedback based on the driving data. The system may comprise an in-vehicle device that includes a graphical user interface and a processor and a data collection device wirelessly connected to the in-vehicle device. The in-vehicle device may be configured to receive vehicle telematics data from the data collection device and the processor may process the telematics data in real time and cause the telematics data to be displayed on the graphical user interface. The graphical user interface may include a speed display and an acceleration display.

An unmanned aerial vehicle manages storage of data and transfer between other connected devices. The unmanned aerial vehicle captures sensor data from sensors on the unmanned aerial vehicle. The unmanned aerial vehicle transfers the captured sensor data from the unmanned aerial vehicle to a remote controller via a wireless interface. The captured data may be transferred via a TCP link, a UDP link, or a combination thereof. If a loss of link is detected, the captured sensor data is stored to a buffer and a battery level of the unmanned aerial vehicle and a flight status of the unmanned aerial vehicle is monitored. The stored sensor data is transferred from the buffer to a non-volatile storage responsive to the battery level dropping below a predefined threshold or detecting that the unmanned aerial vehicle is stationary and a shutdown may be imminent.

A processor may receive a request including a vehicle identifier, a first symptom identifier, and a second symptom identifier. In response to receiving the request, the processor may determine a circuit element identifier to include in a reply to the request. To do so, the processor may make a determination that the received vehicle identifier matches or is mapped to a stored vehicle identifier, that the received first symptom identifier matches or is mapped to a stored first symptom identifier, and that the received second symptom identifier matches or is mapped to a stored second symptom identifier. In response to making the determination, the processor may determine that a particular circuit element identifier is the circuit element identifier to include based on the particular circuit element identifier being mapped to these stored identifiers. Then, the processor may generate and subsequently output the reply including the determined circuit element identifier.

A method for vehicle diagnostics, a diagnostic device, and a non-transitory computer-readable storage medium are provided in the present disclosure. In the method, the diagnostic device obtains a diagnostic request including vehicle information of a vehicle to-be-diagnosed, and determine a communication protocol which is applied in the vehicle to-be-diagnosed according to the vehicle information. After obtaining a diagnostic instruction including a diagnostic function instruction and a communication protocol corresponding to the diagnostic function instruction, the diagnostic device determines a communication link corresponding to the diagnostic function instruction according to the communication protocol corresponding to the diagnostic function instruction, sends the diagnostic function instruction to the vehicle to-be-diagnosed through the communication link corresponding to the diagnostic function instruction, obtains feedback data from the vehicle to-be-diagnosed, and performs diagnostics.
