Abstract
A driving torque control device for a hybrid vehicle has an engine torque estimation unit configured to estimate an engine torque by compensating for a retardation caused by a delay filter in an engine torque instruction value, and a retardation factor selection unit configured to select, as a retardation factor indicating a retardation degree of the delay filter, any one of an increase-side retardation factor for a case where the engine torque instruction value increases and a decrease-side retardation factor for a case where the engine torque instruction value decreases. The retardation factor selection unit performs switching between the increase-side retardation factor and the decrease-side retardation factor in a case where a difference between the engine torque estimation value and the engine torque instruction value as a filter input value is equal to or smaller than a predetermined value.
