  • 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.

  • Publication number: 20110140212
    Abstract: An electromechanical transducer includes: a conductive substrate; multiple elements which are disposed on a first face side of the substrate and which contain cells; grooves; and insulating films. The substrate has a second face which is opposite from the first face. The grooves run from the second face of the substrate to the first face of the substrate in a manner that electrically isolate the multiple elements from one another, thereby dividing the substrate and forming first electrodes. The insulating films are formed on opposing outer side walls of every two adjacent first electrodes across one of the grooves. The width between the insulating films is narrower on the second face side of the substrate than on the first face side of the substrate. The insulating films are thicker on the second face side than on the first face side.
