Abstract

A control system for hybrid vehicles to prevent a reduction in a brake force when an electrical input to a battery is restricted. A controller is configured to execute a regeneration control to deliver a regenerative torque resulting from operating second motor as a generator to the drive wheels, and an engine brake control to deliver a brake torque resulting from a power loss of an engine to the output member. The controller is further configured to select an HV-Lo mode when an input power allowed to accumulate in the battery is smaller than a threshold power.
