  • Publication number: 20240082095
    Abstract: Disclosed is an exoskeleton-type rehabilitation robot system, including: a body part provided on a chair in which a user sits and provided with a robot arm capable of moving left or right based on the user seated on the chair; a conversion part configured to convert a position of the robot arm with respect to the body part; a driving part configured to articulate the robot arm with respect to the body part; and a controller configured to detect a change in a position of the robot arm and control a left or right driving mode of the driving part according to the position of the robot arm. In accordance with such a configuration, the exoskeleton-type rehabilitation robot system of the present invention is provided integrally with a chair, thereby having excellent space utilization. In addition, the user's initial preparation for rehabilitation training is simple, which can improve efficiency.

  • Patent number: 10486496
    Abstract: A method of controlling an air conditioning system for a vehicle is provided. The method includes detecting a cooling mode while the vehicle is being driven and comparing a vent discharge temperature of air with a cooling target temperature set by a user. When the vent discharge temperature is greater than the cooling target temperature the compressor RPM is determined and air is introduced into the vehicle without passing through the interior heat exchanger and the electric heater. When the vent discharge temperature is less than the cooling target temperature, the compressor RPM is determined and a door in the system is opened to guide the air through the interior heat exchanger to heat the air is heated and then the vent discharge temperature is compared with the cooling target temperature again, and the electric heater is operated.

  • Publication number: 20190118619
    Abstract: A method of controlling an air conditioning system for a vehicle is provided. The method includes setting a scheduled heating and performing charging of the battery and the scheduled heating. A desire target temperature (DTT) of a user is then received and a discharge temperature of air supplied into the vehicle is compared with the DTT to adjust revolutions per minute (RPM) of a compressor. When the RPM of the compressor is adjusted the RPM of the compressor is determined based on whether the discharge temperature is the same as the DTT, and whether to operate the electric heater is determined.

  • Patent number: 8594910
    Abstract: Provided are an apparatus and method for preventing the inflow of exhaust gas of a vehicle. The apparatus includes a mode door provided in an air conditioner of a vehicle in such a manner as to close an air inlet, being in air-close mode, so that only inside air is circulated, or to open the air inlet, being in air-open mode, so that outer air is introduced, and a controller designed, in the air-close mode and above a certain vehicle speed, to control the mode door to tilt and open at a certain angle towards the air-open mode.
