Abstract
An engine-motor hybrid vehicle has a power transmission device including a first rotary electric machine and a second rotary electric machine. The first rotary electric machine has a first rotor connected to an engine and a second rotor connected to vehicle wheels. When the engine is in the idling condition, an electronic control apparatus controls the power transmission device to restrict engine vibrations from being transmitted to the vehicle. The electronic control apparatus controls the power transmission device based on a difference in timings of detecting a first rotor position and a second rotor position in the first rotary electric machine. The electronic control apparatus controls the power transmission device to reduce mechanical shocks which occurs immediately after engine operation starting.
