Abstract
Official abstract text for this publication.
A power transmission system for a hybrid vehicle including an engine, a first planetary gearset and a second planetary gear set is provided. In particular, the first planetary gearset includes a plurality of first rotational elements, one of which is coupled with an output shaft of the engine and one of which is coupled with a first motor generator, and two of which are allowed to be directly selectively connected directly by a clutch. The second planetary gearset includes a plurality of second rotational elements, one of which is permanently coupled with one of the first rotational elements of the first planetary gearset, one of which is coupled with a second motor generator and one of which is connected directly with drive unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A power transmission system for a hybrid vehicle comprising: an engine of the hybrid vehicle; a first planetary gearset made up of a first sun gear, a first carrier, and a first ring gear, of which the first sun gear is connected to a first motor generator, of which the first carrier is coupled with an output shaft of the engine, and of which the first ring gear and the first carrier are connected by a clutch wherein when the clutch is engaged, the vehicle operates using a variable gear position as an invariable gear position during high-speed low-load driving; and a second planetary gearset made up of a second sun gear, a second carrier, and a second ring gear, of which the second sun gear is connected to a second motor generator, of which the second carrier is fixedly connected to a brake, and of which the second ring gear is coupled with a drive unit and is permanently coupled with the first ring gear of the first planetary gear set.
