    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, during the travel in limp-home mode with an abnormality detection flag being set to 1, the control device prohibits operation of the EGR device.

    摘要： A hybrid automobile runs by transmitting a power from an engine and a power from a motor-generator MG2, and can store a part of the power from the engine and an electric power generated by a motor-generator MG1. In this hybrid automobile, a power requirement Pr* of a drive shaft is set based on an accelerator opening, and a battery charge electric power Pbi is set based on SOC, and the sum of the power requirement Pr* and the battery charge electric power Pbi are set as an engine target power Pe*. When the engine target power Pe* is less than a predetermined minimum value Plow, the engine target power Pe* is changed to the minimum value Plow. Further, in accordance with this change, the battery charge electric power Pbi is also changed, and the engine and the motor-generators MG1, MG2 are operated. Since the minimum value Plow is set to be a value such that the efficiency with respect to the output of the engine becomes optimal, it is possible to prevent the engine from being operated in a low output region where the efficiency is low.

    摘要： After completion of warm-up of an engine, upon satisfaction of an exhaust gas recirculation condition by setting the drive mode of a hybrid vehicle to a normal mode according to the driver's accelerator operation, when a power difference ΔPe representing a decrease rate of a power demand Pe* required for the engine is less than a preset reference value α, the engine and motors MG1 and MG2 are controlled to ensure output of a power equivalent to the power demand Pe* from the engine with prohibition for exhaust gas recirculation via an EGR valve and to ensure output of a torque equivalent to a torque demand Tr* to a ring gear shaft or an axle (steps S300 to S330 and step S390).
