  • Publication number: 20010051845
    Abstract: A vehicle steering apparatus controller that enables a sub-computer having a capacity lower than that of a main computer to recognize computation results in the same control cycle as the main computer. A main computer of the controller computes an auxiliary torque command value of a steering motor based on the torque of a steering wheel and the velocity of the vehicle in a main control routine. A sub-computer of the controller computes a value equivalent to the command value based on the torque and the vehicle velocity in each cycle of a sub-control routine, which is longer than that of the main control routine. The sub-computer includes a first comparison circuit for comparing the command value and the torque in each cycle of the main control routine and a second comparison circuit for comparing the command value and the equivalent value in each cycle of the sub-control routine.

  • Patent number: 5785377
    Abstract: An article fixture 10 includes a projecting portion 14 which comprises a lower part 16 connected with a base portion 12 and an upper part 18 displaceable along the lower part 16. The upper part 18 is connected at a first height with the lower part 16 through interconnecting portions which can be broken by a predetermined force. When the interconnecting portions are broken, the upper part 18 is displaced into the second height lower than the first height. The upper part 18 has a pawl 24 which is integrally formed and laterally extended adjacent to the top face 18a. The pawl 24 is hooked with the objective body, thereby mechanically locking the projecting portion 14 at a predetermined position on the objective body. The base portion 12 is provided with a resilient hook 26, and the upper part 18 of the projecting portion 14 is provided with a recess 28 into which the resilient hook 28 is engaged. The hook 26 is engaged with the recess 28, thereby the upper part 18 is mechanically held at the second height.
