Patent number: 9457838Abstract: An electric power steering system is provided which can take an abnormality countermeasure without being affected by a torque abnormality signal and without giving an uncomfortable feeling to a driver when torque abnormality occurs. Abnormality of a steering assist command value is detected by employing a dual detection configuration of a main ECU clip (34) and a sub ECU interlock (62). When abnormality of a steering torque Ti detected by a torque sensor (3) is detected, input values to the main ECU clip (34) and the sub ECU interlock (62) are switched from the steering torque Ti detected by the torque sensor (3) to an alternative torque value. Here, the alternative torque value employs a previous torque value calculated based upon the normal steering torque Ti detected by the torque sensor (3) when the abnormality of the steering torque Ti detected by the torque sensor (3) is not detected.Type: GrantFiled: October 24, 2013Date of Patent: October 4, 2016Assignee: NSK Ltd.Inventors: Mikihiko Tsunoda, Mitsunori Okubo, Naoki Sawada

Publication number: 20160273192Abstract: Provided is a hydraulic circuit capable of efficiently recovering one and the other hydraulic energies for utilization by separating and recovering the same, one hydraulic energy being extruded from a hydraulic cylinder and the other hydraulic energy being extruded in starting and stopping rotation of a hydraulic motor, so as to allow an energy density of an accumulator to increase. The hydraulic circuit has: a first accumulator that accumulates pressure of hydraulic oil extruded from a boom cylinder; and a second accumulator that accumulates one pressure of the hydraulic oil relieved when the rotation of a swing motor is started and another pressure of the hydraulic oil extruded from a motor driving circuit with inertial rotation of the swing motor when rotation of the swing motor is stopped. A solenoid switch valve in passages that connect the first second accumulators closes the passages when pressure is accumulated in the second accumulator opens when the pressure in the second accumulator is discharged.Type: ApplicationFiled: November 4, 2014Publication date: September 22, 2016Applicant: Caterpillar SARLInventors: Shigeo Kajita, Kouji Kishida, Naoki Sawada, Nobuaki Matoba
