    摘要： The present application discloses a method and a system for analyzing and predicting a vehicle stay behavior based on multi-task learning, and the method includes the following steps: acquiring vehicle GPS and OBD data including a vehicle ID, a travel start time, a start longitude, a start latitude, an end time, an end longitude, and an end latitude after desensitization; preprocessing vehicle GPS and OBD data to obtain vehicle stay behavior data including stay location and stay duration; extract a spatial-temporal characteristic of the preprocessed vehicle stay behavior data by a deep recurrent neural network; inputting the spatial-temporal characteristic into a multi-task learning and predicting network, and obtaining the correlation between a stay location prediction task and the stay duration prediction task based on the historical stay behavior of the vehicle through the multi-task learning and predicting network to predict the stay location and stay duration.

    摘要： A driving evaluation device includes: an acquisition unit that acquires at least one of vehicle information related to a vehicle state and driving information related to a driving state of drivers; a determination unit that determines whether a predetermined failure operation related to driving has been performed based on at least one of the vehicle information and the driving information acquired by the acquisition unit; and a calculation unit that calculates a failure operation probability that is a probability that the failure operation was performed, based on the failure operation determined by the determination unit, and uses a Z score of the failure operation probability calculated based on the failure operation probability to calculate an evaluation value related to the driving of the drivers.

    摘要： A computer-implemented system and method are provided for state-based payload capture by a work machine comprising ground engaging units supporting a frame, and a work implement moveable with respect to the frame for loading and unloading payloads. At least a first set of sensors associated with the work machine are used to detect event-based transitions between work states in a defined work cycle having a sequence of work states therein, e.g., from digging states to loaded states. An onboard payload measuring unit is used to selectively capture payload data corresponding to a current work cycle in association with the detected transition. The captured payload data is categorized and stored, independently for the current work cycle with respect to associated locations within a work site and/or with respect to time, and in aggregate with other captured payload data for each of a plurality of work cycles for the work machine.

    摘要： The control unit of the server acquires first information including a turn indicator operation time, a steering angular velocity, and a vehicle speed when the turn indicator is operated, from the first vehicle. Based on the acquired first information, the control unit of the server determines that the turn indicator operation performed in the first vehicle is an operation for notifying the behavior of the first vehicle and the turn indicator operation time is It is determined whether or not the operation corresponds to a short-time turn indicator, which is an operation that is equal to or less than the first time length.
