  • VEHICLE BATTERY CASE
    Publication number: 20240075798
    Abstract: Disclosed is a vehicle battery case including: a case body in which a vehicle battery is contained; and a side portion extending in a longitudinal direction of a vehicle and coupled to a side of the case body, thereby protecting a side of the vehicle battery. The side portion includes: a lower panel extending outwards from the case body and having multiple first protrusions formed to protrude upwards; an upper panel disposed above the lower panel and extending outwards from the case body so as to form a closed section together with the lower panel; and a reinforcement panel disposed between the upper panel and the lower panel so as to extend outwards from the case body, thereby reinforcing rigidity of the side portion together with the lower panel and the upper panel.

  • Apparatus for diagnosing abnormality in vehicle sensor and method thereof
    Patent number: 11600120
    Abstract: An apparatus for diagnosing an abnormality of a vehicle sensor is provided. The apparatus includes a sensor configured to measure an acceleration and an angular velocity of a vehicle, a camera configured to generate a front time series image frame of the vehicle, and a controller configured to estimate the acceleration and the angular velocity of the vehicle by using the front time series image frame generated by the camera and diagnose an abnormality in the sensor based on the acceleration and the angular velocity of the vehicle estimated by the controller.

  • Device for classifying road surface and system for controlling terrain mode of vehicle using the same
    Patent number: 11390287
    Abstract: A device for identifying a road surface includes: storage for storing a deep learning-based road surface model; and a controller configured to identify a type of a road surface on which a vehicle is currently traveling, using the road surface model. The device for identifying a road surface can identify a type of a road surface on which the vehicle is traveling based on deep learning and control the terrain mode of the vehicle based on the identified type of the road surface. The type of the road surface on which the vehicle is traveling may be identified with a high accuracy and an optimal terrain mode may be set, thereby improving not only travel stability but also riding comfort of the vehicle.
