Description

A kind of electric automobile intelligent control system
Technical field
The invention belongs to automobile manufacturing field, particularly relate to a kind of electric automobile intelligent control system.
Background technology
Electronlmobil is to be the automobile of power with the electricity, appears at 1873 the earliest, and British Luo Baichi Dai Weisen has made first electronlmobil with practical value, and this battery-driven car was than also Zao more than 10 years of the automobile of Ka Erbenci.From the history of development of automobile, its fullsized fuel-engined vehicle of electronlmobil (EV, Electric Vehicle) also will early be born, but is subjected to the limitation of battery and Drive Control Technique, and its development but lags far behind fuel-engined vehicle.Though fuel-engined vehicle has brought development to bring convenience to the mankind to national economy, but also brought huge disaster to the mankind, 42% environmental pollution is the discharging that derives from fuel-engined vehicle, 80% city noise is produced by the vehicle, world today's oil reserves reduces day by day, and fuel-engined vehicle is the rich and influential family who consumes petroleum.Thereby the current automobile industry development direction that certainly will seek low noise, zero-emission, the comprehensive application energy.Can predict electronlmobil will be the important vehicle of 21 century, and electronlmobil has comfortable clean, advantage such as noise is low, free from environmental pollution, operation is simple and reliable and operating costs is low.
During "the 10th five-years", China has dropped into 1,000,000,000 Renminbi exploitation electronlmobil.Electronlmobil is listed in country " 15 " high-tech brainstorm project, be listed in country " 863 " key scientific and technological projects simultaneously, support the prospective technological development of battery-driven car, this does not also comprise basic research such as raw-material research, complete fuel cell and other propulsions source.Under the playing an active part in of local government and each large enterprises, the industrialization of new-energy automobile also " is spurred on the flying horse ".National Development and Reform Committee has has formally publicized and implemented the administrative provisions of " new-energy automobile production access rule " and " vehicle manufacturing enterprise and product announcement " in last Nov, and beginning to organize to set up national new-energy automobile technical policy, science and technology begins to manifest to the facilitation of economy.
What electronlmobil carried is people's life, and safety is the key of system's operation.Electronlmobil be unable to do without electronic control system, no matter be the place with car or manned vehicle, or the construction machinery and equipment car, the electronic control system of electronlmobil is also more important than the driving engine of present fuel-engined vehicle.The Security Control Problem of electronlmobil is exactly in fact to solve the reliability of electronics actuating system and the deadlock problem of process software computing how.Also there are not at present complete electronic system and the software system of a cover fully to mate the safe and reliable operation of controlling whole battery-driven car.Therefore, development one cover complete function, stable and reliable operation, adaptable intelligence control system seem especially necessary.
The CAN bus is for solving a kind of communication protocol that control numerous in the automobile and the data exchange between the testing tool are developed.Because the CAN bus has outstanding reliability, real-time and alerting ability, thereby has obtained the extensive approval and the utilization of industry, and formally becomes international standard and industry standard in 1993, is described as one of " the most promising fieldbus ".The application of bussing technique on automobile that with CAN is representative not only reduced body harness, also improved the reliability of automobile.
