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.
A continuous variable planetary (CVP) system for a vehicle, the CVP system comprising:
A method of controlling a continuous variable planetary (CVP) hub of a CVP system for a vehicle, the CVP hub configurable to operate across a range of transmission speed ratios, the CVP hub including a set of tiltable planet assemblies including a set of tiltable planets, such that a tilt of the set of tiltable planets controls a transmission speed ratio of the range of transmission speed ratios, the CVP hub further including a shift driver configured to modify the tilt of the set of tiltable planets to shift the CVP hub across the range of transmission speed ratios, the method comprising:
