1. A vehicle control device mounted on a vehicle including:
an engine;
a clutch provided on a power transmission path between the engine and a drive wheel;
a first rotary electric machine connected to the drive wheel;
a second rotary electric machine connected to the engine; and
a power storage device for supplying electric power to the first rotary electric machine and the second rotary electric machine,
the vehicle further including a first traveling mode in which the vehicle travels using torque output from the first rotary electric machine driven by electric power from the power storage device, in a state in which the clutch is released and the engine is stopped, and
a second traveling mode in which the engine is operated with the clutch engaged and the vehicle travels using torque output from the engine and the torque output from the first rotary electric machine driven by electric power from the power storage device, wherein
a first section and a second section are included in a period until a clutch engagement at a time of starting the engine when shifting from the first traveling mode to the second traveling mode, the first section being a section for cranking the engine by an output of the second rotary electric machine, and the second section being a section after the first section and a section for assisting a driving force of the engine by an output of the first rotary electric machine, and
the vehicle control device performs control for limiting an increase in the torque of the first rotary electric machine in the first section.
