| description | The present invention relates to an optimal battery efficiency operation control method for a vehicle. The optimal battery efficiency operation control method of the vehicle according to one embodiment of the present invention comprises: a first step of modeling a longitudinal motion equation of the vehicle as a status variable based on a vehicle speed-related status variable and a wheel drive input variable; a second step of calculating a wheel power using the status variable and the input variable; a third step of calculating a battery power using the wheel power calculation; a fourth step of approximating the battery power; and a fifth step of using the approximated battery power as an objective function and applying at least one constraint condition to calculate a minimum solution and output a wheel drive control target. An objective of the present invention is to provide the optimal battery efficiency operation control method for the eco-friendly vehicle driven by the battery power.
