A running locus generating apparatus 1 for generating a future running locus of a vehicle driven by a hybrid scheme comprises constraint condition computing means 30 for convergently computing a constraint condition including at least a road boundary condition and evaluation function computing means 30 for deriving a running locus by a convergent computation with an evaluation function including at least an evaluation of an electric power balance in a hybrid system when the electric power balance is positive in a state where the constraint condition by the constraint condition computing means 30 is satisfied.
