  • Patent number: 11975772
    Abstract: A steering control device includes an electronic control unit that stores an end position corresponding angle. The electronic control unit is configured to execute end strike relaxation control, to execute partial release control in a case where turning of a vehicle is attempted during execution of the end strike relaxation control, to make a non-following determination and acquire a release-time restriction position determination angle that corresponds to the absolute steering angle detected at a time when the electronic control unit determines that the movement of the steered shaft is restricted, and to permit update of the end position corresponding angle based on the release-time restriction position determination angle, and update the end position corresponding angle in a case where the update of the end position corresponding angle is permitted.

  • Patent number: 11926375
    Abstract: A steering control device includes an electronic control unit. The electronic control unit is configured to acquire a limit position determination angle corresponding to an absolute steering angle when it is determined that movement of a turning shaft is limited, to compare a first stroke width which is a sum of an absolute value of the limit position determination angle on a right side and an absolute value of the limit position determination angle on a left side with a stroke threshold value corresponding to an entire stroke range of the turning shaft when the limit position determination angles on the right and left sides are acquired, and to set end-position-corresponding angles on the right and left sides based on the limit position determination angles on the right and left sides when the first stroke width is greater than the stroke threshold value.

  • Patent number: 11919581
    Abstract: A steering control device includes an electronic control unit. The electronic control unit is configured to perform end contact relaxation control for correcting a current command value such that a decrease of an end separation angle indicating a distance of an absolute steering angle from an end-position-corresponding angle is limited when the end separation angle is equal to or less than a predetermined angle and to perform partial release control for decreasing a correction value of the current command value due to execution of the end contact relaxation control based on a steering torque which is input to a steering system when a vehicle is intended to travel while turning at the time of execution of the end contact relaxation control.

  • Patent number: 8544718
    Abstract: The aim is to provide a paper container for liquid that has a strength to prevent breakage or leakage due to a shock in a long-distance transportation and also has no problems in opening the container when used. This invention is a paper container for liquid which comprises a laminated body which comprises a paper as base material thereof and a heat-sealant layer which is placed inner side of the container than the paper and which comprises a reinforcement layer and a liquid-contacting layer which is the side of contacting the liquid, wherein the reinforcement layer is a layer made of linear low-density polyethylene and the liquid-contacting layer is a layer made of low-density polyethylene and thickness ratio of the reinforcement layer and the liquid-contacting layer (thickness of reinforcement layer 5/thickness of liquid-contacting layer 6) that form the heat-sealant layer is in the range of 0.2-5. Moreover, it is characterized in that the density of the linear low-density polyethylene is in a range of 0.
