Integrated variable speed driving device and electrically controlled energy and management system of hybrid electric vehicle

Abstract

The invention discloses an intelligent variable speed driving device and an electrically controlled energy and management system of a hybrid electric vehicle, relates to the innovation of a power coupling mode of the key technology of new energy energy-saving automobiles, and provides multi-scheme configuration compatible products with a great demand in the market, such as an integrated continuously variable transmission ITA / B-C, an integrated hybrid electric driver IDA / B-H, an integrated plug-in hybrid electric driver IDA / B-P, an integrated extended-range electric driver IDA / BE-R, etc. In the invention, a product series which nearly covers the working modes of almost all power transmission systems of the new energy energy-saving automobiles is established by integrally building three modular structures, i.e., an electric control system ECS, an energy system ES and a management system (MBS) thereof based on a basic platform of a motor power assembly MPA module technology, therefore, the automobile has the advantages of greater safety, energy saving and emission reduction, longer cruising distance, higher cost performance, and higher practicability, contribution to standardization, serialization and universalization of the products of enterprises and capabilities of obviously reducing research and development period, effectively reducing the cost and guaranteeing greater long-term competitive advantage in the market of the product.

Description

technical field [0001] The invention belongs to the technical field of new energy and energy-saving automobile power transmission systems, and in particular relates to an integrated variable speed driving device and an electronically controlled energy source and management system of a multi-program hybrid electric vehicle. Background technique [0002] Today, with the growing demand for safety, energy saving and emission reduction, all countries in the world are rushing to invest huge sums of money in the research and development of new energy and energy-saving vehicles. The four major systems of mode, power battery pack, motor and controller have become the bottleneck restricting the development of my country's electric vehicle industry. [0003] In the description of the Chinese invention patent "Integrated stepless automatic variable speed driving device for hybrid electric vehicles" (Patent No.: ZL 200810086323.1) and the utility model patent of the same name (Patent...
