  • Patent number: 7778753
    Abstract: A vehicle operation assist system includes as assist yaw rate calculator which calculates a necessary moving amount to avoid an obstacle based on a detection result of the obstacle by a radar device, and a vehicle movement controller controls lateral movement of the vehicle based on the calculated moving amount. When an avoiding operation detector determines initiation of an obstacle avoiding operation by the driver, the vehicle movement controller operates a braking device to control the lateral movement of the vehicle, so that the obstacle can be reliably avoided. When a restoring operation detector determines initiation of a restoring operation, the vehicle movement controller operates a power steering device to control the lateral movement of the vehicle, so that delay in the steering operation by the driver, and excessive restoring operation of the steering handle to compensate for the delay are suppressed, thus stabilizing vehicle behavior.

  • Patent number: 7472562
    Abstract: A refrigerant go-around passage is provided in a housing of a compressor. The passage takes in refrigerant discharged from a compression mechanism into the housing, makes the refrigerant go around an axial line of the compressor and finally returns the refrigerant to the discharge-port side of the housing while separating liquid contained in the refrigerant from the refrigerant by centrifugation or by centrifugation and collision. In the mid portion of the refrigerant go-around passage, a liquid returning port is provided for returning the separated liquid to the housing in such a manner that the liquid returning port has an orientation that has a component in a direction of gravity and that is deviated from a traveling direction of the refrigerant.
