CONTROL APPARATUS FOR VEHICLE

摘要

Provided is a control apparatus applied to a hybrid vehicle provided with a dual clutch transmission in which a first input shaft is connected via a first clutch to an internal combustion engine and a second input shaft is connected via a second clutch to the internal combustion engine; a first motor generator connected to the first input shaft; and a second motor generator connected to the second input shaft. The first clutch is a normally open clutch, and the second clutch is a normally closed clutch. When detecting that hydraulic pressure is impossible to be supplied from a hydraulic supply system to both clutches, retreat travel is performed whereby a drive wheel is driven with the power of the first motor generator while the second motor generator is driven by the internal combustion engine for generating electricity.

1. A control apparatus applied to a vehicle, the vehicle comprising:
an internal combustion engine, a dual clutch transmission: having an input system including a fist input shaft connected to the internal combustion engine via a first clutch and a second input shaft connected to the internal combustion engine via a second clutch, an output system connected power-transmittably to a drive wheel, and a plurality of gear trains, one part of the plurality of gear trains intervening between the first input shaft and the output system and remaining ones of the plurality of gear trains intervening between the second input shaft and the output system, gear ratios of the plurality of gear trains being different from each other; and capable of changing a gear stage between a plurality of gear stages by changing a gear train to be used for power transmission between the input system and the output system, a first motor generator connected power-transmittably to the first input shaft, a second motor generator connected power-transmittably to the second input shaft, and a battery connected electrically to the first motor generator and the second motor generator, wherein the first clutch is a normally open clutch which operates hydraulically and when the hydraulic pressure is not supplied, changes over to a release state where power is shut off between the internal combustion engine and the first input shaft, the second clutch is a normally closed clutch operating hydraulically and, when the hydraulic pressure is not supplied, changing over to an engagement state where power is transmitted between the internal combustion engine and the second input shaft, the vehicle is provided with a hydraulic supply device supplying hydraulic pressure to each of the first clutch and the second clutch, and the control apparatus includes a computer programmed to function as a control device which is configured to perform, when detecting that the hydraulic pressure is impossible to be supplied from the hydraulic supply device to both of the first clutch and the second clutch, retreat travel where, while the second motor generator is driven by the internal combustion engine to generate electricity, the drive wheel is driven by power of the first motor generator.
