Motor driving control apparatus

A motor-assisted vehicle, comprising:

• a motor;
• and
• a motor driving control apparatus, comprising:
• a first signal generator configured to generate a first signal representing any one rotation angle section of a plurality of rotation angle sections according to a sensor signal that changes every predetermined rotation angle of a rotor of the motor, wherein each of the plurality of rotation angle sections has the predetermined rotation angle;
• a measurement unit configured to measure a period of each of the plurality of rotation angle sections according to the sensor signal;
• a prediction unit configured to predict a period of a next rotation section based on one or plural rotation angle sections measured by the measurement unit;
• a second signal generator configured to generate a second signal representing a relative rotation angle of the rotor in the next rotation angle section for each period that is obtained by dividing the predicted period by a predetermined number;
• and
• a third signal generator configured to generate a third signal corresponding to a rotation angle of the rotor based on the first and second signals.
