The present disclosure relates to a method and apparatus for determining optimal load balancing in a vehicle. According to an embodiment of the present disclosure, the method for determining optimal load balancing of an operation amount in a vehicle may be provided, the method comprising the steps of: acquiring at least one time-independent first element; acquiring at least one time-dependent second element with a predetermined time period as a cycle; determining, on the basis of the at least one first element and the at least one second element, a clock frequency of an operation device in the vehicle, which minimizes energy consumption of the vehicle, a first operation amount to be transmitted from the operation device to an edge, and a second operation amount to be transmitted from the operation device to a cloud; transmitting the first operation amount to the edge and transmitting the second operation amount to the cloud; and performing an operation on the basis of the clock frequency.
