  • Publication number: 20220242396
    Abstract: A control apparatus for a vehicle is configured to be applied to a hybrid vehicle that includes an electric motor and an engine that are coupled to a drive wheel. The control apparatus includes a transmission mechanism and a torque processor. The transmission mechanism is to be provided between the engine and the drive wheel, and configured to switch between a plurality of fixed gear ratios to perform a shift. The torque processor is configured to temporarily decrease a torque of the electric motor and a torque of the engine upon execution of an upshift of the transmission mechanism, and configured to decrease, before the execution of the upshift of the transmission mechanism, a proportion of the torque of the electric motor to a drive wheel torque of the drive wheel as compared with a recent proportion of the torque of the electric motor to the drive wheel torque.

  • Patent number: 7696469
    Abstract: The present invention can be used in a multi-optical axis photoelectric sensor indicating an operating status thereof to a non-safety control device. The present invention allows the multi-optical axis photoelectric sensor so as to become a easier operation. The multi-optical axis photoelectric sensor has a control unit to providing a safety control signal representing a result of a distinguish portion in a normal operating status, a safety control signal representing operation non-allowable in an abnormal status and a safety control signal representing operation allowable in a special operating status. The multi-optical axis photoelectric sensor also has an operating status indication portion for determining an operating status of the multi-optical axis photoelectric sensor from the normal operating status, the abnormal status and the special operating status, and providing the operating status to an external device via the same output line regardless of the result of the determination.

  • Patent number: 7368702
    Abstract: A multi-optical-path photoelectric safety apparatus or a light curtain is placed in front of a pressing machine or a folding machine. Optical paths are set as a floating blanking area B (some paths out of a large number of optical paths) in the light curtain. The operation of the pressing machine or folding machine is forcibly stopped when two contiguous optical paths are blocked in the floating blanking area B. On the other hand, the normal protection function serves in areas A and C between which area B is sandwiched. In these areas A and C, if any one optical path enters a light blocked state, the operation of the pressing machine or folding machine is immediately stopped.

  • Patent number: 6784415
    Abstract: A method of installing a multi-beam photoelectric safeguard system for making a light curtain of closely aligned light beams closely to a pressing machine first positions main light emitting and detecting devices (11, 12). The method next mounts a projecting portion (21) to the pressing machine and identifies optical axes interrupted by the projecting portion (21). Subsequently, after setting a sub light detecting device (13) adjacent to one side of the projecting portion (21), the method adjusts optical axes between the sub light detecting device (13) and the main light emitting device (11). Finally, after setting a sub light emitting device (14) adjacent to the other side of the projecting portion (21), the methods adjusts optical axes between the sub light emitting device (14) and the main light detecting device (12).
