Claim Text:
1. A vehicle control device comprising: an engine and a first motor generator from both of which a driving force for traveling is output to drive wheels; a second motor generator that can perform motoring of the engine, the motoring of the engine is an increase in a rotational speed of the engine; a power split mechanism that splits and transmits power of the engine to the second motor generator and the drive wheels; and an electricity storage device that stores electric power for driving the first motor generator, wherein, when a vehicle weight is in a reference state at a time of deceleration braking, at least the first motor generator is caused, out of the first motor generator and the engine, to generate a first braking force, and when the vehicle weight is greater than that in the reference state at the time of deceleration braking, at least the engine is caused, out of the first motor generator and the engine, to generate a second braking force, when the vehicle weight is greater than that in the reference state, a portion of the second braking force by the first motor generator is less than a portion of the first braking force by the first motor generator when the vehicle weight is in the reference state, wherein, when the vehicle weight is greater than that in the reference state, the motoring of the engine is performed by the second motor generator so as to generate at least a portion of the second braking force by engine brake.
