DRIVE CONTROL DEVICE OF HYBRID VEHICLE

摘要

In a drive control apparatus (1) of a hybrid vehicle, provisional target engine power calculating means (17D) of control means (17) compares provisional target engine power which is calculated from a target drive power and a target charge/discharge power with a target engine power lower limit value and, when the provisional target engine power is smaller than the target engine power lower limit value, sets the target engine power lower limit value to the provisional target engine power. Motor torque instruction value operating means (17L) of the control means (17) calculates a torque instruction value of each of a plurality of motor generators (4, 5) by using a torque balance equation including a target engine torque which is obtained from a target engine operation point and an electric power balance equation including a target electric power. Thus, such a situation that the target engine power is set to a low power in dependence on a vehicle speed is reduced, and when a large drive force is requested, an output can be raised so as to make a response to such a request.
