Dynamic hybrid vehicle system for adjusting motor rotary position

A non-transitory computer-readable storage medium storing instructions that are executable by a processor, and upon such execution causes the processor to perform operations comprising:

• receiving one or more signals that represent an angular speed of a permanent magnet electric motor of a hybrid electric vehicle, the one or more signals being provided by an angular sensor connected to the permanent magnet electric motor;
• receiving a signal representing a voltage from the permanent magnet electric motor, the voltage being a direct axis voltage component of a three-phase motor model, wherein the one or more signals that represent the angular speed and the signal representing the voltage of the permanent magnet electric motor are received with zero current supplied to the permanent magnet electric motor and motion of the hybrid electric vehicle being supplied by an internal combustion engine;
• determining when the angular speed is within a predetermined threshold;
• calculating an error angle representing a correction offset for an alignment of the angular sensor of the permanent magnet electric motor based on a ratio of the voltage and the angular speed;
• storing the correction offset;
• determining a Boolean value to represent a status of the error angle;
• repeating the receiving the one or more signals, receiving a signal, determining when the angular speed, calculating an error angle, storing the correction offset, and determining a Boolean value steps until the Boolean value changes from a default status;
• and
• controlling for the correction offset of the angular sensor by halting current supply when the Boolean value is the default status and supplying current when the Boolean value changes from the default status.
