CONTROL SYSTEM FOR HYBRID VEHICLE

摘要

A control system for a hybrid vehicle is provided to suppress noise generated by an application of excessive torque to a torsional damper. A controller predicts that a limit torque is applied to the input member. If an application of the limit torque to the input member is expected, the controller restricts an output torque of an engine while adjusting an output torque of the motor to compensate a reduction in a drive force resulting from a restriction of the engine torque.

1. A control system for a hybrid vehicle, comprising:
an engine; a torsional damper in which an input member and a relative member are moved relatively to each other in a rotational direction by a pulsation of a torque of the engine applied to the input member; a motor that is disposed on a power train between the torsional damper and drive wheels; and a controller for controlling the engine and the motor that is configured to: predict that a limit torque by which a relative movement of the relative member to the input member is increased to be equal to or greater than a first predetermined value is applied to the input member; and restrict the torque of the engine to be lower than the limit torque while adjusting an output torque of the motor to compensate a reduction in a drive force resulting from a restriction of the torque of the engine, in a case that an application of the limit torque to the input member is expected.
