PROBLEM TO BE SOLVED: To prevent generation of a speed change shock by carrying out control for a non-driving mode even though in a driving mode at the time of shift change during automatic travelling control. SOLUTION: Automatic travelling control to control output of a motor and a working gear step of an automatic transmission is carried out so as to adjust vehicle travelling speed. Thereafter, at the time of carrying out shift-change of the automatic transmission during automatic travelling control, either of a standard driving mode and a standard non-driving mode is maintained during shift-change. Hereby, the standard driving mode is a mode free to define that output torque of the motor is in a state where it is larger than travelling resistance and does not include an ambiguous region where the driving mode/the non-driving mode cannot be discriminated. In the same way, the standard non- driving mode is a mode free to define that output torque of the motor is in a state where it is smaller than travelling resistance. |
