    摘要: The present disclosure relates to a computer-implemented method for training of machine learning models in person accident event assessment. The method comprises preparing (S200) training data, by obtaining and automatically acquiring (S210) sensor data generated from sensors (2, 3; 6, 7) at an initial group (200) of subjects (201a-201c), and dividing (S220) the group (200) of subjects (201a-201c) into sub-groups (200a-200h) associated with certain corresponding features that are unique for the subjects (201a-201c) in that sub-group (200a-200h). The method further comprises training (S400) an initial machine learning model for the subjects in the initial group (200) and training (S500) a plurality of machine learning sub-models for the subjects (201a-201c) in the corresponding sub-group (200a-200h), such that one machine learning sub-model for each sub-group (200a-200h) is obtained.

    摘要: The present disclosure relates to a computer-implemented method for training of a machine learning model in vehicle accident event assessment. The method comprises implementing (S100) the machine learning model, and preparing (S200) training data by obtaining and automatically acquiring (S210) sensor data generated from vehicle sensors (2, 3; 4, 5). The method further comprises applying data augmentation on the collected data to artificially increase the amount of collected data acquired from each sensor such that an augmented data set is acquired for each sensor.
    For each sensor (2, 3; 4, 5), applying data augmentation (5220) comprises transforming (S221) the collected data to apply to a plurality of different sensor mounting positions and/or a plurality of different sensor mounting orientations within a certain sensor mounting area (6, 7), such that a further data set is obtained, the augmented data set comprising the collected data and the further data set. The method further comprises training (S300) the machine learning model using the augmented data set for each sensor (2, 3; 4, 5).

    摘要: A seat belt retracting and locking apparatus and an automotive seat. The seat belt retracting and locking apparatus includes a seat belt retractor (1), a sensor having a sensing seat (21) and a sensing ball (22), and a locking mechanism (3) for locking the sensing seat (21). When the locking mechanism (3) is in a locking state, the sensing seat (21) is fixed in an initial position. When the locking mechanism (3) is in an unlocking state, the sensing seat (21) is rotatable relative to the axis of a first pivot shaft (212), and the sensing seat (21) remains in the initial position. When the seat belt retracting and locking apparatus (3) and the automotive seat are in a normal state, the sensing seat (21) is locked in the initial position by the locking mechanism (3), and the angle and the position of the sensing seat (21) are not affected by a change in the speed of a vehicle, so that relative positions between the sensing ball (22), a pawl (14), and a ratchet (13) do not change, thereby improving the stability of the performance of the product.

    摘要: Disclosed are a vehicle sensor device and a seat belt retractor equipped with the same. The vehicle sensor device includes a body that forms an external appearance, a cover coupled to an opened one surface of the body, a sensor housing rotatably installed in the body according to an installation angle of the body and an inclination of a backrest, a ball installed inside the sensor housing to sense changes in the inclination and acceleration of the vehicle, and a sensor lever disposed on an upper portion of the ball and having one end rotatably coupled to the sensor housing. The sensor lever linearly reciprocates a pilot lever provided in a locking device by a rotation action according to movement of the ball. The sensor lever is installed in the sensor housing where the ball is installed, and the sensor lever is rotated about a rotating shaft coupled to the sensor housing by the movement of the ball according to the change in inclination and acceleration of the vehicle to linearly reciprocate the pilot lever connected to the sensor lever, thereby allowing the pilot lever to be engaged with or disengaged from the locking device. Thus, the normal control range of the pilot lever can be extended.
