DRIVE SYSTEM OF A HYBRID VEHICLE

摘要

The present invention has a purpose to provide a driving system for a hybrid vehicle, which is configured to suppress the occurrence of deceleration sensation when restarting-up a system. When restarting-up a hybrid driving system (5) in a state of being temporarily suspended, a clutch (CL2) is hooked to be adjusted after setting a rotation speed difference (ΔN) between a carrier (C1) of a first planet gear unit (14) and a ring gear (R2) of a second planet gear unit (16) which are subjects for hooking and adjusting to be smaller than a critical value (N_bo) regulated by at least one output torque of a first motor (MG1) and a second motor (MG2), thereby preferably suppressing the occurrence of a deceleration sensation at restarting-up into ready-on after turning the hybrid driving system (5) to ready-off. That is, an electronic control device (30) of a driving unit (10) to suppress the occurrence of a deceleration sensation in a restarting-up of the hybrid driving system (5) can be provided.
