  • Patent number: 11982291
    Abstract: A blower unit for a vehicle and an air conditioning device including the same, the blower unit including: a scroll casing having an inlet port; a fan rotatably disposed in the scroll casing; a motor having a shaft coupled to the fan; and a bell mouth disposed in the inlet port, in which an inner end of the scroll casing, which defines the inlet port, is disposed to be spaced apart from the fan in a radial direction to define a separation space, and the bell mouth prevents air, which flows by a rotation of the fan, from flowing reversely through the separation space. The blower unit and the air conditioning device including the same prevent air from flowing reversely to the outside of the scroll casing by means of the arrangement of the bell mouth and the scroll casing and the structural shape of the bell mouth.

  • Publication number: 20230150500
    Abstract: Disclosed are an apparatus and method for determining a cut-in of a vehicle. The apparatus includes a sensor that detects surroundings of the vehicle to generate a point cloud, and a controller that calculates a distance from a starting point to an obstacle based on the point cloud, calculates a distance ratio based on the distance to the obstacle, analyzes the distance ratio by using an artificial neural network, and determines whether a surrounding vehicle cuts in and a cut-in direction. Therefore, it is possible to quickly and accurately determine a cut-in vehicle by minimizing the operation load and increasing the accuracy of the determination performance.
