A method for controlling a vehicle (101) on a mission, the vehicle (101) comprising a first and a second power source (ICE, EM) for driving the vehicle (101) itself, the method comprising the steps of: solving an optimal control problem based on a mathematical model of the vehicle (101), the optimal control problem involving at least one state variable (Eb); the solving including minimizing a cost function, with respect to first and second control variable (i, P) and subject to a set of constraints, based on Pontryagin's minimum principle and based on minimization of a Hamiltonian function (H), associated to the optimal control problem, with respect to the first control variable (i), the second control variable (P), and a costate variable (λ); and controlling the vehicle (101) based on the solution of the optimal control problem.
