Abstract
A hybrid electric vehicle is arranged such that a driving force of an engine and a driving force of an electric motor can be transmitted to driving wheels through an automatic transmission having a plurality of forward gears. When it is detected that the vehicle is in a predetermined state in which it is difficult for the electric motor to output an upper limit torque predetermined as a generable maximum torque, a vehicle ECU controls the automatic transmission using a gear shift map configured such that the automatic transmission is downshifted earlier in accordance with a change in the operating state of the vehicle and upshifted later in accordance with a change in the operating state of the vehicle in comparison with a gear shift map that is used when it is not detected that the vehicle is in the predetermined state.
