CONTROL DEVICE OF HYBRID VEHICLE FOR RESTRICTING LOWERING OF DRIVABILITY IN LOWERING FUNCTION OF VARIABLE SPEED RATIO CONTROL UNIT

摘要

PURPOSE: A control device of a hybrid vehicle is provided to prevent lowering of drivability in lowering function of a variable speed ratio control unit by generating control pressure according to shifting condition of the transmission. CONSTITUTION: A control device of a hybrid vehicle is composed of a first driving source and a second driving source transmitting power to a wheel of the vehicle, a power distribution unit distributing power from the first driving source to the wheel and a rotating apparatus, a transmission arranged in the power transmission passage from the second driving source to the wheel, and variable speed ratio control units(SL1,SL2) controlling the variable speed ratio. A specific control unit(88) prevents lowering of drivability in lowering function of the variable speed ratio control units by controlling the transmission.
