A hybrid electric vehicle includes a wet clutch device (C1, C2) configured to establish and interrupt connection between an engine (1) and an electric motor (3), and a transmission (2) capable of being switched between a driving range (D range) in which driving force can be transmitted to driving wheels (14) and a non-driving range (P range, N range) in which transmission of the driving force is interrupted. When a battery temperature (TB) is not less than a warm-up determination value TB0 while the vehicle is at a standstill with the transmission (2) switched to the non-driving range, the wet clutch device (C1, C2) is kept disengaged, and on the other hand, when the battery temperature (TB) is less than the warm-up determination value TB0, a battery warm-up control unit (21) switches the wet clutch device (C1, C2) into engaged state to connect the engine (1) and the electric motor (3) together and vary driving force of the electric motor (3) alternately to a positive side and a negative side so as to repeatedly charge and discharge the battery 5.
