A drive control device for providing drive control for a hybrid vehicle and hybrid vehicle

摘要

Torque applied to a one-way clutch (1) when a first motor-generator (4) and a second motor-generator (5) are operated in a motor-generator drive mode is restricted or prevented from becoming excessively high, setting a first motor-generator division fraction (cf1) in response to a drive torque target Tdvt for the vehicle by controlling the operation of the first motor-generator (4) in response to a first motor-generator division fraction (cf1), when it is likely that vehicle vibrations occur due to cogging torque and by decreasing the torque from the first motor generator (4) when the driving torque target Tdvt is large. Moment applied to the one-way clutch (1), which would otherwise become excessively high immediately after stopping the engine, is restricted or prevented by taking the torque from the first motor generator (4) in response to the second motor-generator split fraction (FIG. cf2) is reduced when the machine downtime test is short.
