摘要： PROBLEM TO BE SOLVED: To provide a driving force change control device having excellent reliability which prevents a vehicle from being impossible to travel even when a position switch to detect a driving state is failed, or an electric contact is short-circuited.
SOLUTION: A control means of an actuator of a driving force changing device stores a pattern of a present position switch, and detects an abnormality when the next pattern is different from the pattern estimated from the pattern map. In a driving force change control device, even when a worm wheel as a rotating body used for detecting the rotation of the actuator to change the driving state of a vehicle and a plurality of position switches arranged in a housing are failed, the failed state is determined from the preliminarily stored pattern corresponding to the driving state of the vehicle, and the driving state is not changed any more. Thus, continuous drive of the actuator for a long time can be avoided, and breakage of a motor can be prevented.
