摘要： An infinitely variable transmission includes an input assembly, an output assembly, an input/output planetary ratio assembly and a torque feedback control is provided. The input assembly is coupled to receive input rotational motion. The output assembly provides a rotational output. The output assembly is configured to be rotationally coupled to a load. The input/output planetary ratio assembly sets an input to output speed ratio. The input/output ratio assembly includes a first and a second stator. The torque feedback control assembly provides torque feedback to the input/output planetary ratio assembly to at least in part control the input to output speed ratio of the input/output planetary ratio assembly. The torque feedback control assembly includes a phase relation system operationally coupled to the first and second stator and a torque system operationally coupled to the output assembly. The phase relation system further is in operational communication with the torque system.

摘要： A continuous variable planetary (CVP) system includes a CVP hub, which includes a shift mechanism including a shift driver element, and a processing server system to calibrate the CVP system and detect errors within the CVP system. The processing server system performs continuously monitoring or obtaining a transmission speed ratio of the CVP hub. Upon detecting that the transmission speed ratio reaches a particular value, the processing server system records a corresponding position of the shift driver. The processing server system calibrates the CVP system based on the particular value, the corresponding position, and a known relationship between transmission speed ratios and positions of the shift mechanism. The processing server system determines or verifies a full underdrive (FUD) position by iteratively reducing a transmission speed ratio from the particular value until an onset of a backlash condition is detected and determines or verifies a full overdrive (FOD) position.
