Intelligent hybrid management system for new energy vehicle

Abstract

The invention discloses an intelligent hybrid management system for a new energy vehicle. The intelligent hybrid management system for the new energy vehicle comprises a hybrid vehicle control unit HCU, an electronic stability control unit ESP, an engine control unit ECU, a motor control unit MCU, a power generator control unit GCU, a battery management system BMS, an automatic transmission control unit TCU and an air conditioning compressor control system EAS, wherein the control units communicate with each other by using a PROFIBUS-DP bus; the intelligent hybrid management system for the new energy vehicle further comprises a field bus instrument with a CPU processor function; the field bus instrument can detect digital signals, connect actually measured data to the PROFIBUS-DP bus through a DP / PA coupler and transmit the actually measured data to each control unit through the bus. The intelligent hybrid management system for the new energy vehicle is advantaged in that the time can be saved, pollutant emissions can be reduced, economic, applicable, safe and reliable operation of the new energy vehicle can be ensured, and good economic benefit and environmental protection benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of energy saving and new energy vehicles, in particular to an intelligent hybrid management system for new energy vehicles. [0002] Background technique. [0003] With the continuous and rapid development of my country's economy and the acceleration of urbanization, the demand for automobiles will continue to grow for a long period of time in the future, and the problems of energy shortage and environmental pollution will become more prominent. Immediately after the country implemented policies such as environmental pollution, energy crisis, and restrictions on travel and purchase, more and more new energy vehicles entered the market, and their safety, quality, reliability, economical practicability, and service life also received more attention. As an important part of new energy vehicles, the new energy vehicle management system plays a decisive role in the operation of new energy vehicles, including safet...

Problems solved by technology

In the current related technologies, one is that most of the hybrid vehicles adopt the preheating method of idling the engine in situ, that is to say, the engine does not work externally, and is in an idling state, and it will not start until the temperature of the engine reaches a certain preset value. put in gear, refuel and drive; second, in terms of power battery preheating, currently vehicles do not have a battery preheating function. Very low, unable to heat the power battery

Third, when the temperature of the power battery is low, the charging and discharging performance is greatly affected by the environment, which affects the normal use of users
