Abstract
A vehicle, including a motor having a rotor, a resolver that detects a rotation angle of the rotor and a control device, and a control method for the vehicle are provided. The control device executes rectangular-wave control over the motor using the rotation angle of the rotor, detected by the resolver, executes zero learning for learning a deviation between an origin of an actual rotation angle of the rotor and an origin of the detected rotation angle of the rotor, corrects the detected rotation angle of the rotor on the basis of a result of the zero learning, and, when the zero learning has not been completed yet, executes avoidance control for avoiding a rapid variation in output of the motor.
