Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, also can obtain other accompanying drawing according to these accompanying drawings.
The distributed energy of electric automobile regulate and control method diagram of circuit that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with accompanying drawing 1 and detailed description of the invention, the present invention is further detailed explanation.
A kind of distributed energy of electric automobile regulate and control method, comprises the steps:
Step 1, when vehicle is in standing, when ignition lock is in and closes gear, on vehicle, whether each controller detects the consumer be connected with self and closes, if close, then order the controller satisfied condition to enter one-level sleep state, respectively enter the dormant controller of one-level and continue to detect bus, if message information do not detected within a certain period of time, then order enters the dormant controller of one-level and enters secondary sleep state.
After each controller enters one-level sleep state, first according to a definite sequence, (this order is by user's self-defining for each controller, can according to the number order of memory device in internal memory, the topological structure of the controller in the present embodiment is: first controller sends message to second controller, the like, last controller is transmitted to first controller after receiving the message of a controller) send broadcast and notify that other controllers self have been in one-level sleep state, after the message sent when last controller is detected by first controller, prove that all controllers have entered one-level sleep state all.Now the power consumption of control unit will reduce one-level, then each controller can monitor Related arousal source in setting-up time (this time is set voluntarily by user), if during this period of time vehicle-state is without any change, each controller can enter second stage sleep state and ECU sleep, the quiescent current of each controller is down to minimum this moment, can reach a microampere rank.Now vehicle enters sleep state completely, and car load quiescent current will be down to minimum.This Time Controller can continue to monitor whole vehicle state, having vehicle to use intention (i.e. wake source), waking all controllers up, recover the normal electrical airway dysfunction of car load by bus when identifying chaufeur.Wake source in the present embodiment comprises ignition lock gear signal, vehicle speed signal, whether car door is opened or closed signal, whether central controlled lock switch is pressed etc.
Car load quiescent current cross conference cause vehicle occur the short time park after the phenomenon that can not start, the reason generally causing this situation to occur has two kinds, and the first there is abnormal wake source to stop vehicle to enter sleep state; The second there is exception control device to wake vehicle up.Can be identified by OSEK Network Management Function in the present embodiment and record above-mentioned reason.If ignition lock to be in after OFF gear 15 minutes, controller does not receive the sleep prompting position of some other controllers, then in internal storage region, record corresponding controller failure identifier namely show that there is abnormal wake source stops vehicle to enter sleep.When ignition lock be in OFF gear and controller send sleep confirm order after 10 seconds in, controller monitors again in bus and occurs that message then records identifier corresponding to this fault in internal storage region, to show having abnormal wake source to occur.The diagnostic code stored in controller can adopt diagnostic installation to be read by vehicle diagnostics interface, for analyzing the fault got rid of and cause vehicle quiescent current excessive.
Step 102, when automobile is in driving condition, detects battery condition, if detect, storage battery is in negative balance state, collection vehicle real-time status data, compares with the threshold value of setting, the consumer not meeting setting threshold is closed, keeps electrical generator to be continuously storage battery power supply.
The real-time status data gathered comprise power supply voltage signal and voltage-duration signal, vehicle speed signal, engine rotational speed signal and the battery outer ambient temperature signal of controller end.
The entry condition of each controller is set: allow when driving engine is greater than a certain rotating speed high power load to start, close related load when driving engine is less than a certain rotating speed, compared by collection engine rotational speed signal with entry condition, when meeting entry condition, allow to open, otherwise, close.Such as: controller can by CAN/LIN bus receive high power load (vehicle voltage can be caused fluctuate when referring to and himself open or close, namely occur the appreciable phenomenon of chaufeur as dimmed in interior light light/variable, audible sound the load of situation such as become greatly/diminish) as the mode of operation of electronic rear Defrost heater, headlight, air conditioner blower, rain shaving electrical machine and the information on load etc. of generation current machine.
Such as, when consumer is rear defrosting electro heat load, controller can judge engine revolution, carries out Threshold Analysis, such as setting threshold is: revolution is defrosting electro heat load after more than 600rpm starts, and revolution defrosts electro heat load after 500rpm then closes.Detect engine revolution, after engine revolution reaches 600rpm, rear defrost heater just can be allowed to open; Automatically defrost heater function after closing after engine revolution drops to 500rpm, prevents accumulator electric-quantity from depleting.
For another example, when consumer is air conditioner blower, controller can control air conditioner blower with reference to engine condition.Controller can receive engine rotational speed signal from bus, and when judging that driving engine does not work, maximum can allow the work of blowing engine half load; When judging driving engine place in the running, just can allow blowing engine can full load operation.When engine running, if controller judges that Current vehicle current consumer power consumption is comparatively large, when generator load is higher, the rotating speed of blowing engine can be reduced equally, thus ensure to there will not be the situation of accumulator feeding to occur.
Utilize the battery outer ambient temperature signal collected, in the process of charging of electrical generator to storage battery, improve or reduce the rotating speed of present engine, the power distribution of each current consumer is adjusted by the horsepower output of regulator generator, such as, when controller detects ambient temperature at-20 DEG C, according to the pressure-temperature curve of storage battery self-characteristic, the charging valtage regulating storage battery is 14.8V; And ambient temperature is 40 DEG C time, regulate the charging valtage of storage battery to be 14V, the method can extend service life of storage battery by actv., can reduce oil consumption simultaneously.
When controller identify self be in under-voltage or overvoltage condition after store corresponding diagnostic code and send to information display unit by bus, give chaufeur information.
Above to invention has been detailed introduction, applying specific case herein and setting forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
