There are provided a motor control apparatus, an electric power steering apparatus, and a vehicle, capable of controlling the driving of an electric motor accurately even when a failure occurs in a motor electric angle detecting unit that detects a motor electric angle. The motor control apparatus includes: a relative offset amount estimating unit (62) that estimates a relative offset amount (¸off) between a reference value (¸osr) of an output shaft rotational angle detection value (¸os) of a steering shaft (12), detected by an output-side rotational angle sensor (13c), and a motor electric angle original point (¸md) of a three-phase electric motor (22); and a motor electric angle estimating unit (63) that calculates a motor electric angle estimate (¸me) based on the output shaft rotational angle (¸os) and the relative offset amount (¸off), wherein when at least either one of a resolver (23a) and an angle computing unit (60) is abnormal, the driving of the three-phase electric motor (22) is controlled based on the motor electric angle estimate (¸me) estimated by the motor electric angle estimating unit (63).
