PROBLEM TO BE SOLVED: To provide a control device capable of accurately distinguishing and determining a condition of a vehicle towing a trailer or the like from a condition of hill-climbing travelling.SOLUTION: A control device calculates a vehicle acceleration as a variation of a vehicle speed VP per unit time (S21); calculates a vehicle drive force in accordance with an output torque of an engine (S11); and calculates a travelling resistance of the vehicle in accordance with the vehicle speed (S12) and calculates an estimated inclination acceleration on the basis of the vehicle drive force and the travelling resistance (S14). Further, the control device detects an inclination vehicle acceleration that corresponds to the sum of the inclination acceleration caused by the inclination of a road where the vehicle is travelling and the vehicle acceleration, and calculates the difference as an actual inclination acceleration between the inclination vehicle acceleration and the vehicle acceleration (S22, S23). The control device calculates the difference as a towing determination value DACTR between the estimated inclination acceleration and the actual inclination acceleration (S31); and determines that the vehicle is in a towing condition if the towing determination value DACTR is equal to or more than a prescribed threshold DTFTH1 (S33, S34). |
