A vehicle includes connecting/disconnecting mechanisms (20,30) disposed on power transmission paths between first rotating electric machines (3,4) mounted on the vehicle and an output shaft (12) that drives a wheel, a first rotating electric machine speed sensor (43,44) that detects a rotation speed of the first rotating electric machine (3,4) as a first rotation speed (Nm,Ng), and a wheel speed sensor (42) that detects a rotation speed of the wheel as a wheel speed (Nw). A control unit (5) includes: a first calculator (5B) that calculates an axle rotation speed (Nam,Nag) representing a rotation speed of the output shaft (12) based on the first rotation speed (Nm,Ng) in a state where the first connecting/disconnecting mechanism (20,30) is engaged; a monitoring unit (5C) that calculates a deviation (X,Y) between the axle rotation speed (Nam,Nag) calculated by the first calculator (5B) and the wheel speed (Nw); and a second calculator (5D) that calculates the axle rotation speed (Nax,Nay) by calibrating the wheel speed (Nw) based on the calculated deviation (X,Y) in a state where the first connecting/disconnecting mechanism (20,30) is disengaged.
