Background technology
Energy shortage and environmental pollution are two challenges greatly that present automobile industry development runs into.Pertinent data shows, in the urban atmosphere 82% of CO, NO
x48%, 58% and the particulate of HC 8% all from the waste gas of auto emission; According to the prediction of national environmental protection center, the motor vehicle exhaust emission amount was with 64% of duty gas source of pollution in 2010.On the other hand, the oil resources of China are less relatively, and since 1994, China was oil importers just, therefore the energy-conservation schedule of just having put on; Simultaneously, after the enforcement fuel oil tax, the fuel economy that improves automobile becomes user's greatest requirements.
Therefore, developing the mixed power car that engine emission and oil consumption are reduced is the development tendency that meets the modern national conditions of China.
Summary of the invention
Purpose of the present invention just provides a kind of control system of Weak hybrid power automobile, is intended to improve the fuel oil consumption and the exhaust emissions index of vehicle according to the intention control driving engine of chaufeur and the mode of operation of motor.
For achieving the above object, the technical solution used in the present invention is: a kind of control system of Weak hybrid power automobile, it is characterized in that: system comprises that entire car controller, electric machine controller, engine controller ECU, low-voltage-powered storage battery, motor, gearbox controller TCU and battery management system BMS form, the entire car controller and the electric machine controller that wherein constitute hybrid controller are gathered on-off signal, analog signal and ABS signal in order to judge the motoring condition of vehicle, by carrying out the running that driving engine is controlled in communication between CAN and the EMS.
The present invention just is based on a kind of hardware system of Weak hybrid power automobile; this control system can realize the function of the idle stop of driving engine; in the process that vehicle is being exercised; when running into red light, hybrid controller will be controlled driving engine by EMS according to the intention of chaufeur; engine idle is shut down; thereby fuel oil consumption that the idling operation of having avoided conventional car causes and exhaust emissions have been saved the energy to a certain extent, have reduced environmental pollution.
Summary of drawings
Fig. 1 is the dynamic assembly structural principle block diagram of Weak hybrid power automobile;
Fig. 2 is a control system block diagram of the present invention.
The specific embodiment
The control system of Weak hybrid power automobile disclosed by the invention comprises that entire car controller 10, electric machine controller 20, the low-voltage-powered storage battery 40 of engine controller ECU30,12V, motor 50, gearbox controller TCU60 form, the entire car controller 10 and the electric machine controller 20 that wherein constitute hybrid controller are gathered on-off signal, analog signal and ABS signal in order to judge the motoring condition of vehicle, by carrying out the running that driving engine is controlled in communication between CAN and the EMS.
The clutch engagement signal of described hybrid controller collection vehicle, neutral position switch signal, vehicle speed signal, engine rotational speed signal judge whether chaufeur has the intention requirement that enters the idle stop state.
When judging whether chaufeur has the intention that enters the idle stop state to require; hybrid controller can detect temperature, the vacuum pressure of battery, the state of each current consumer waits the state that whether can enter idle stop of judging; then still be not in the electric power generation state if do not satisfy condition, then enter the idle stop state if meet the demands.
When chaufeur was made corresponding action, hybrid controller was judged the intention that chaufeur has start the engine, and then start the engine enters the generating state of motor.
Described electric machine controller 20 is an inverter, and the three plase alternating current and the output DC that receive motor 50 generations arrive low-voltage-powered storage battery 40.
Below in conjunction with accompanying drawing control process of the present invention is described.
Control system operates mainly in following several modes:
Power generation mode: the motor 50 of this moment is as electrical generator work, hybrid controller is gathered some digital signals, the signal of analog signal and ABS is judged the state that chaufeur is in normal enforcement, then by carrying out communication between CAN and the EMS, control the running of driving engine, will charge the battery according to the state of the battery that collects simultaneously, electrically-charged threshold value is set in controller, and this kind pattern is general normal enforcement pattern.
The idling pattern: hybrid controller is by gathering the signal on some vehicle bodies; such as clutch engagement signal; the neutral position switch signal; vehicle speed signal; engine rotational speed signal etc.; the intention of judging chaufeur requires to enter the idle stop state; this moment, hybrid controller can detect the temperature of battery; vacuum pressure; the state of each current consumer waits the state that whether can enter idle stop of judging; then still be not in the electric power generation state if do not satisfy condition; then enter the idle stop state if meet the demands; when chaufeur is made corresponding action; hybrid controller is judged the intention that chaufeur has start the engine, then controls the generating state that the EMS start the engine enters motor.
" shut " mode": motor is in off position, wants electric motor starting is got up and can only start by key switch.The control system of Weak hybrid power automobile disclosed by the invention comprises that entire car controller 10, electric machine controller 20, the low-voltage-powered storage battery 40 of engine controller ECU30,12V, motor 50, gearbox controller TCU60 form, the entire car controller 10 and the electric machine controller 20 that wherein constitute hybrid controller are gathered on-off signal, analog signal and ABS signal in order to judge the motoring condition of vehicle, by carrying out the running that driving engine is controlled in communication between CAN and the EMS.
Among Fig. 2; motor 50 can be used as starter motor and electrical generator uses; entire car controller 10 and electric machine controller 20 are core components of the present invention; entire car controller 10 and electric machine controller 20 carry out communication by the CAN bus of special use; electric machine controller 20 is inverters; the three plase alternating current that motor produces can be converted to the direct current (DC) that can give the low-voltage-powered storage battery 40 of 12V; entire car controller 10 detects the various digital signals of car load; analog signal; vehicle speed signal and engine rotational speed signal; the battery temperature signal waits the intention of judging chaufeur; thereby make corresponding judgment and action in view of the above; and by carrying out communication with electric machine controller 20; the control motor is in the pattern of which kind of work; realize the mutual conversion between the AC/DC; judge the state of battery simultaneously; whether decision charges the battery; thereby mode of operation that can monitoring battery; electric weight deficiency when the low-voltage-powered storage battery 40 of 12V; can make corresponding action under the situation such as aging; such as forbidding that driving engine enters the state of idle stop; enter generating state and give 12V low-voltage-powered storage battery 40 chargings; or remind chaufeur will in time change battery; certainly entire car controller is also by peripheral CAN bus and ABS; EMS; car body controllers etc. carry out communication; by gathering the signal on these car loads; detect the correlation behavior of car load electrical equipment; the foundation of judgement is provided for next step action of entire car controller 10; simultaneously; entire car controller 10 can be by detecting these signals; remind the condition of service of these devices of chaufeur; whether need to change etc., and can show by instrument.
