  • Publication number: 20210309237
    Abstract: A vehicle program update system and a vehicle program update method are provided which update a vehicle program that is used to control a vehicle by an on-board control device mounted on the vehicle to an update program received by the vehicle from an external device separate from the vehicle via wireless communication. When the update of the vehicle program is completed, determination is made whether the updated vehicle program is normal. When determination is made that the updated vehicle program is not normal, control of the vehicle is switched from control that is performed by the on-board control device using the vehicle program to limp home control for performing a limp home operation in which the vehicle travels using a driving force from a vehicle driving force source without being controlled by the on-board control device.

  • Patent number: 6814558
    Abstract: The present invention provides a ball screw device for linear movement, which moves a working body by using a single of a plurality of ball screw shafts and ball screw nuts. In the ball screw device, a plurality of ball screw nuts are engaged threadedly with the same ball screw shaft. Also, one of the ball screw nuts on each ball screw shaft is attached to the working body via a fixed flange, the single fixed flange or one of the fixed flanges is provided with a load sensor, and other ball screw nuts serve as a fluid pressure supporting mechanism using a cylinder and a piston. A fluid pressure is controlled so that the support force of the fluid pressure supporting mechanism is equal to the pushing force detected by the load sensor. By this configuration, a large load can be distributed evenly to the ball screw nuts.

  • Patent number: 5269202
    Abstract: A cup-type harmonic gear drive comprises a rigid circular spline, a cup-shaped flexspline disposed inside the circular spline and a wave generator means fitted inside the flexspline for flexing the flexspline into elliptic to engage it with the circular spline and for rotating the engagement portions to thereby produce relative rotation between the splines. The flexspline has a tube, a disc-shaped diaphragm connected integrally to the end of said tube to define the cup bottom, and a thick boss formed on the center of the diaphragm. The diaphragm has a root portion from the boss, a thickness of which is set at least about three times the minimum thickness of the diaphragm. The outer profile of the diaphragm is defined, when viewed along a plane including the axis of the flexspline, by a plurality of curves having a different curvature. These curves are arranged from one having a larger curvature from the root protion to the tube portion of the diaphragm.
