  • Patent number: 6698542
    Abstract: The steering device for vehicle changes the steering angle by transmitting the movements of the steering electrical actuator to the vehicle wheels. When the vehicle is steered in the stationary state, the hydraulic fluid can be supplied to the steering assistance force generating hydraulic actuator from the pump within the hydraulic pressure imparting unit. When the vehicle is not steered in the stationary state, the hydraulic fluid can be supplied to the brake device from the pump via the hydraulic pressure distribution unit.

  • Patent number: 6470250
    Abstract: A vehicle attitude control apparatus, wherein a corrected behavior index value for steering is determined in such a manner that the deviation between a target behavior index value for a vehicle and a corrected behavior index value for steering decreases, as an instability index value correlating to the amount of under-steer increases, and when the target behavior index value and the behavior index value are equal, the corrected behavior index value for steering is set to equal the behavior index value. A corrected behavior index value for braking is determined in such a manner that the deviation between the target behavior index value and a corrected behavior index value for braking increases, as the instability index value increases, and when the target behavior index value and the behavior index value are equal, the corrected behavior index value for braking is set to equal the behavior index value.

  • Patent number: 6458010
    Abstract: An jointed tail of a pet robot can be configured simply and driven to curve freely and autonomously by fitting an jointed cylindrical member 25 around outer circumferences of two wire portions 24a and 24b composed of a wire 24 which is folded nearly into a shape of a hair pin, rotatingly driving two driven ends 24d and 24e on a side opposite to a tip 24c of the two wire portions 24a and 24b connected to each other around an X axis and a Y axis with a differential gear mechanism 38, and moving and controlling two driven ends 26d and 26e reversibly in an axial direction at a swing limit position around the X axis, thereby autonomously curving a tip of the wire 24.

  • Patent number: 6450592
    Abstract: A braking system for a motor vehicle is provided, which has an attitude control function. The system includes: a first attitude control circuit for stabilizing the behavior of the motor vehicle by controlling the operation of a steering mechanism of the motor vehicle; a second attitude control circuit for stabilizing the behavior of the motor vehicle by controlling a braking mechanism for applying a braking force to vehicle wheels of the motor vehicle; and a braking control circuit for causing the braking mechanism to generate a maximum braking force on condition that an attitude control is performed for the stabilization of the behavior of the motor vehicle by the first attitude control circuit when a braking command is inputted thereto.

  • Patent number: 6438474
    Abstract: An ECU (2) of a vehicle executes under-steering control when a steering wheel is operated in the direction to increase the steering angle under an under-steering state and the yaw rate does not increase. The under-steering control is not executed under such a driven under-steering state that the vehicle is cornering while applying the engine power to the driven wheels. The under-steering control is executed only under such a condition that although the steering wheel is operated in the direction to increase the steering angle, the actual yaw rate &phgr; does not change and not follow the operation. Thus, in the vehicle, when the under-steering control for restraining the under-steering state or the over-steering control for restraining the over-steering state is executed during the cornering motion of the vehicle, the condition for executing the under-steering control or the over-steering control is adequately set.

  • Patent number: 6374162
    Abstract: An apparatus for controlling behavior of a vehicle has an ECU (2) which estimates behavior of a yaw rate of the vehicle using a first target yaw rate, a second target yaw rate and an actual yaw rate to control the behavior of the yaw rate. The ECU (2) completes the behavior control if a completion condition is achieved during over-steering control of the vehicle. The completion condition is any one of the following matters. The steering wheel is operated to increase the steering angle. The vehicle is running straight in a stable state. The deviation between the second target yaw rate and the actual yaw rate is stable in a region lower than a preset value. The estimative brake fluid pressure is approximately identical to the fluid pressure of the master cylinder. The slip angle is small. The absolute values of the first and second target yaw rates and the absolute value of the actual yaw rate are smaller and approximately resemble to one another.

  • Patent number: 6354588
    Abstract: A discharged paper receiver unit for receiving papers discharged from an image recording apparatus has a bottom plate on which papers discharged from the image recording apparatus are stacked and which is positioned with its one end held lower than the other at least when the discharged paper receiver unit is set in its operative position. A stopper member has a cushioning portion positioned so that the leading end of each paper as discharged from the image recording apparatus directly impacts against the cushioning portion and the paper falls onto the bottom plate.

  • Patent number: 6333386
    Abstract: A relatively small amount of a plasticizer having an SP value of at least 8.8 and a molecular weight of at most 550 is added to blend rubber of NBR-PVC in which NBR has an AN content of from 43 to 50% by weight. The fuel impermeability and the low-temperature flexibility of the resulting rubber composition are improved to be comparable to those of FKM, and the amount of the plasticizer and its reaction product to be released from the rubber composition in fuel is reduced. Adding a controlled amount of carbon black to the rubber composition makes the composition have favorable electroconductivity. The rubber composition is formed into hoses or electroconductive hoses of low fuel permeation.
