    摘要: 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.

    摘要: A front lens group 1 and a rear lens group 2 having a diameter of about 5 mm held inside a cylindrical body 5 are capable of movement in the forward and backward directions via a front group movable body 3 and a rear group movable body 4, respectively. An image taking element such as a CCD is arranged at a prescribed position behind the cylindrical body. By setting the distance from each lens group to the CCD and the distance between both lens groups, an image is formed at a prescribed zoom on the CCD. From the 1× base state when the zoom magnification is made α×→β×→γ×, the positional relationship between the front lens group and the rear lens group becomes as shown in FIG. 1(b)˜(d). The two kinds of zoom magnification 1× and β× can be switched by fixing the front lens group and moving only the rear lens group back and forth between positions.
