Abstract:
In a hybrid vehicle control apparatus, a motor control unit executes input power control on a MG unit to stabilize a system voltage. This input power control for MG unit is executed independently from torque control on an AC motor so that the input power control and the torque control are stabilized. The motor control unit further adjusts a current control gain for torque control in accordance with an input power amount of the MG unit. As a result, the current control gains of a q-axis current and a d-axis current for torque control are varied in correspondence to variations in torque variation rate in the q-axis direction and the d-axis direction in accordance with the input power amount, so that the torque is restricted from varying with variations in the q-axis current or the d-axis current.
