Patent number: 10520079Abstract: A transmission controller comprises an actuator which changes a roller position of a toroidal CVT to adjust the tilt motion angle of a power roller; a tilt motion angle information generation unit which generates information of the tilt motion angle; a position estimation unit which derives an estimated value of the roller position; and a position control unit which derives an operation command value of the actuator so that a deviation between a command value of the roller position and the estimated value of the roller position is cancelled. The position estimation unit is configured to derive the estimated value based on the information of the tilt motion angle which is generated by the tilt motion angle information generation unit, and the operation command value, and to compensate the estimated value based on an environment parameter which affects an operation of the power roller.Type: GrantFiled: March 8, 2016Date of Patent: December 31, 2019Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Kenichi Nakashima, Yukinobu Kohno, Tatsuhiko Goi

Patent number: 7006905Abstract: Force balance and moment balance associated with thrust of air and water craft equipped with thrust generators are preset in view of non-linear characteristics and dynamic characteristics of thrust generators. A performance index for minimizing thrusts generated by the thrust generators is defined. Using the balance as restricting condition, propeller thrusts of the thrust generators and rudder angles and changing speeds of rudders that minimize the performance index are calculated.Type: GrantFiled: September 30, 2004Date of Patent: February 28, 2006Assignees: Kawasaki Jukogyo Kabushiki Kaisha, Kabushiki Kaisha Kawasaki ZosenInventors: Masanori Hamamatsu, Yukinobu Kohno, Masaaki Higashi, Kenichi Nakashima, Yasuo Saito, Hiroshi Ohnishi
