  • Patent number: 11618381
    Abstract: A safe exit warning apparatus and method for an occupant may include a first sensor that detects position of the occupant in the vehicle, a second sensor that detects an approaching object from the vehicle's blind spot, a warning device that warns the occupant about collision with the object, and a controller that determines the occupant's intent to get out of the vehicle by monitoring the position of the occupant in the vehicle when the vehicle stops and that controls the warning device to warn the occupant about the collision with the approaching object.

  • Publication number: 20220289273
    Abstract: A method of correcting torque offset of a motor-driven power steering motor, may include activating a lane following assist (LFA) function by an LFA unit of a vehicle, acquiring a comparison range for determining whether the torque offset of the motor included in a motor-driven power steering (MDPS) unit of the vehicle is present under a predetermined comparison condition during a first travel of the vehicle, and determining a relationship coefficient based on a current required torque value required by the LFA unit and a current measured torque value of the motor, acquired by applying the current required torque value by the MDPS unit, and determining whether torque offset of the motor is present when the determined relationship coefficient is within the comparison range during a second travel performed after the first travel and performed in a lane having the same lane condition as the first travel.

  • Patent number: 9850697
    Abstract: The present disclosure relates to a safety power window system capable of detecting jamming of an object between a window and a door frame by generating virtual pulse signals on the basis of pulse signals generated by two hall sensors positioned to have an interval of 90 degrees therebetween to calculate force acting on the window even though a window motor rotates only 0.75 turns, and an operation method thereof.
