Abstract
An HV-ECU executes a control process including the step of executing reverse rotation prevention control for an engine when EV running is in execution in a vehicle (YES in S100), an ABS is usable (YES in S102) and a magnitude of an amount of change in rotation speed of a ring gear of a differential unit is larger than a threshold value A (YES in S104), or when the ABS is unusable (NO in S102) and a magnitude of an amount of reduction in rotation speed of the ring gear of the differential unit is larger than a threshold value B (YES in S106).
Claims6
A vehicle comprising:
- a planetary gear mechanism having a sun gear, a ring gear and a carrier;
- an internal combustion engine coupled to said carrier and configured to rotate in a predetermined direction at the time of actuation;
- a drive wheel coupled to one rotation element which is one of said sun gear and said ring gear;
- and
- a rotating electric machine provided on a motive power transfer path between said one rotation element and said drive wheel,
- when said vehicle is running by using said rotating electric machine, with said internal combustion engine stopped, and a magnitude of an amount of change in rotation speed of said one rotation element is larger than a threshold value, said vehicle being controlled to actuate said internal combustion engine.

- and
- a clutch for switching a state between said internal combustion engine and said drive wheel from one of a motive power transfer state and a motive power interruption state to the other,
- when said vehicle is running by using said rotating electric machine, with said internal combustion engine stopped, and a magnitude of an amount of change in rotation speed of said one rotation element is larger than a threshold value, said clutch being controlled to bring about said motive power interruption state.
