DEVICE FOR CONTROLLING HYBRID VEHICLE AND METHOD FOR CONTROLLING HYBRID VEHICLE

摘要

A control device for a hybrid vehicle causes the hybrid vehicle to travel in limp-home mode with motive power from an engine when either a motor or a battery for travel cannot be used. The engine incorporated in the hybrid vehicle includes an EGR device for recirculating part of exhaust gas to an intake system of the engine again. Even if an operation state of the engine satisfies a prescribed EGR permission condition for operating the EGR device (YES at step S12), during the travel in limp-home mode with an abnormality detection flag FD being set to 1 (NO at step S13), the control device prohibits operation of the EGR device (step S15).
