Abstract
In a hybrid vehicle configured such that a sun gear, a carrier and a ring gear of a planetary gear are respectively connected with a rotating shaft of a motor MG, a crankshaft of an engine and a driveshaft and that a motor MGis connected with the driveshaft, when a required braking force that is to be output to the driveshaft is equal to or less than a reference value Tref in an accelerator-off state, the braking force by engine braking is output to the driveshaft by motoring of the engine by the motor MG. When the required braking force becomes greater than the reference value Tref, on the other hand, the power output from the engine by load operation of the engine in a reverse rotating direction is output as the braking force to the driveshaft.
