摘要： In control devices of electric power steering systems, steering characteristics are improved by control being carried out by means of a signal based on rotor speed or steering angle after failure of a torque sensor is detected. In the present invention, in a control device of an electric power steering system for controlling a motor applying a steering assist force to a steering mechanism on the basis of a current control value computed from a motor current value and a steering assist command value computed on the basis of a steering torque in a steering shaft, two over-current detecting circuits have different detection current values; when an over-current is detected by the circuit having the lower current detection value within the response time of current control, the duty of PWM for driving the motor is restricted, and when an over-current is detected by the circuit having the higher current detection value, motor current output is stopped and a relay is opened and the system is disengaged from the steering mechanism.

摘要： A control apparatus for an electric power steering system ensures convergence of a yaw rate of a vehicle without discomforting a driver, thus improving steerage of the vehicle. The control apparatus controls a motor that provides a steering mechanism with a steering assist force based on a current control value. The current control value is computed from a steering assist command value, which is computed based on a steering torque generated on a steering shaft, and from a motor current value. In the control apparatus, a rate of change in the yaw rate of the vehicle is detected, based on which damping is applied on the yaw rate.

摘要： The present invention relates to an anchoring system and method for installing exterior materials to a building structure particularly suited for when the exterior materials are to be placed at a distance from the building structure. The anchoring system utilizes a separator rod having two ends wherein one end is secured within a nut joint embedded in the exterior material and the other end is attached to an anchoring device anchored to the building structure. The anchoring device has a speed nut which accepts the other end of the separator rod, allowing the rod to advance into the anchoring device but which inhibits movement of the separator rod out of and away from the anchoring device in a rachet fashion.
