Abstract
An ECU executes a program that includes the steps of setting a vehicle speed to the minimum wheel speed among wheel speeds of four wheels of a vehicle; calculating a difference between the wheel speeds of right and left driven wheels; turning an abnormality flag on when a higher wheel speed is higher than a value obtained by multiplaying a lower wheel speed by α; and determining that the vehicle is turning, and turning a turning flag on, when the abnormality flag is off, a predetermined time has not elapsed after the turning flag is turned on, and the difference between the wheel speeds is equal to or larger than a map value obtained using a map where a vehicle speed is used as a parameter.
