    摘要： In accordance with the present invention, a preferred method is disclosed for operating a transfer case synchronized range shift mechanism. The range shift mechanism can be selectively actuated for establishing a four-wheel high-range drive mode, a neutral mode, and a four-wheel low-range drive mode. The synchronized range shift mechanism is comprised of a first input gear system, a second input gear system, and an output gear system. The output gear system is comprised of a rotary output member that may be selectively engaged with either the first input gear system or the second input gear system, depending on which four-wheel-drive operating mode the vehicle operator selects. The range shift mechanism is further comprised of a synchronizing mechanism. The present invention discloses a novel method for controlling the speed of the range shift as a means for reducing the time it takes to perform the range shift.

    摘要： A torque transfer system for transferring torque between a first rotary member and a second rotary member includes a clutch pack that is operably disposed between the first rotary member and the second rotary member to regulate torque transfer therebetween and a clutch actuator for regulating engagement of the clutch pack. A controller generates a dithered control signal by superimposing a dithering signal onto a digital control signal. The controller determines a time averaged duty cycle DCavg of the dithered control signal, determines an amplitude AMP of the dithered control signal, determines a wave function WF that describes a wave shape of the dithered control signal and calculates a pulse duty cycle PDC for each pulse of the dithered control signal using the average duty cycle, amplitude, and wave function.

    摘要： The present invention discloses a preferred method for operating a adaptive clutch system of the type used in a motor vehicle power transfer assembly by employing a dithered control signal. One aspect of the present invention superimposes a dithering signal onto a control signal by nulling consecutive blocks of control signal pulses. Another aspect of the present invention provides a method for generating a dithered control signal by providing a wave function with which to systematically vary a duty cycle of the dithered control signal. A method for varying the output force of a clutch actuator assembly in response to the dithered control signal is also provided.

    摘要： A mechanical system that assembles or deploys pre-stressed structures. The assembly or deployment process outputs and elastically deforms material to form flexural members having a sinusoidal shape and stored potential energy. The sinusoidal shaped members are oriented and deployed with support members as they take shape. Sinusoidal shaped members are formed from a series of contiguous flexures; each flexure's properties may be engineered using a simulation technique. Each flexure is formed from a region of a sinusoidal member's length that begins and ends at antinodes. During assembly or deployment support members are positioned at antinodes maintaining the flexures' shapes and the assembly's pre-stressed state. By controlling the forces applied to and position of each flexure formed during assembly, the distribution of potential energy within the assembly and its secondary shape can be engineered. Elastic potential energy may be harvested from the material forming the flexural members.
