Hybrid vehicle control apparatus

摘要

A hybrid vehicle control apparatus controls an engine that rotates at least one first wheel and a mechanically independent electric motor that rotates at least one second wheel. The hybrid vehicle control apparatus stabilizes the vehicle driving performance when there is a change in the portion of the total drive torque that should be carried by the engine. Thus, the hybrid vehicle control apparatus prevents degradation of the vehicle driving performance due to the response of the engine when the drive force distribution is shifted. The target drive torque of the engine driven wheels is calculated by multiplying the total target drive torque by a rear wheel drive force distribution ratio. The target drive torque of the motor driven wheels is calculated by estimating the actual drive torque of the engine driven wheels and subtracting this estimated value from the total target drive torque.
