The electronic control unit sets a target value of a charging amount of the electrical storage device and increases the charging amount to the target value during traveling on the freeway. The electronic control unit computes a first travel cost being cost per unit travel distance of fuel used when the EV travel is made by using the electric power charged in the electrical storage device at a time when the HV travel is made on the freeway, and the second travel cost being cost per unit travel distance of the electric power used when the EV travel is made by using the electric power charged in the electrical storage device by the charging mechanism at the destination. The electronic control unit sets the target value on the basis of a comparison result between the first travel cost and the second travel cost.

Hybrid vehicle

A hybrid system includes an electrical motor generating motive power, a storing portion providing electrical power to the electrical motor, a fuel cell that provides electrical power to the electrical motor or the storing portion within a predetermined output range, an internal combustion engine absorbing loading of the fuel cell, a determination portion that determines whether the loading of the fuel cell is above the maximum output in the predetermined range, and a control portion that controls the internal combustion engine so as to operate if it is determined that the loading of the fuel cell is above the maximum output in the predetermined range.
