A powertrain system includes an internal combustion engine, an electric motor, a battery and a control device. The control device is configured to: execute a control input determination processing to solve an optimization problem that minimizes a fuel consumption amount mf during the control time period while taking dynamics of a charging rate SOC as a constraint, and thereby calculate one or more control input values; and execute a system control processing. The control input determination processing includes: a co-state variable determination processing to update a co-state variable p for each time step while using, as an initial value thereof, a final value or an average value thereof during the last control time period; and a control input calculation processing to use the determined co-state variable p and search for and calculate, for each time step, the one or more control input values that minimize an Hamiltonian H.
