HYBRID VEHICLE AND CONTROL METHOD THEREFOR

摘要

A hybrid vehicle generates vehicle driving force by the sum of a direct torque mechanically transmitted directly from an engine (100) to a drive shaft (135) through a power split device (130) and an output torque of an MG (120). A PM-ECU (170) selectively applies a running mode in which outputs of the engine (100) and the MG (120) are controlled such that the requested driving force for the entire vehicle is exerted on the drive shaft (135); and an S/D mode in which the requested driving force is exerted on the drive shaft (135) by the direct torque in the state where the output torque of the MG (120) is set at zero. An MG-ECU (172) stops the operation of a power converter for controlling the output of the MG (120) when the S/D mode is applied.
