Description
Technical Field
The invention belongs to the technical field of advanced manufacturing of automobile generators, and particularly relates to an intelligent energy-saving control method for pre-excitation current rotating speed response of an automobile generator.
Background
With technological advances, particularly the development of the automotive industry, automobiles have become essential vehicles for social production and people's lives. The generator in the automobile is used as a main electromechanical energy device in the automobile, and because the generator needs to bear the requirements of large load and long-time continuous work, how to efficiently save energy, reduce temperature rise, improve operation reliability and prolong service life of the generator becomes an important technical factor of the generator of the automobile.
The existing automobile engines are mostly excitation type generators without permanent magnets, the automobile generators can run for power generation from the stop, rotor windings of the automobile generators need to be electrified and excited, the excitation begins to consume the electric energy of a storage battery when the engines are started, and the excitation current is directly switched on to reach the current value of 4-6A, because the existing automobile generators are provided with larger output power for a vehicle-mounted electronic system, the excitation power of the generators is increased, the direct-current resistance of the excitation windings is very small, the direct-current resistance of the excitation windings of the 120A12V generators is generally 2.0-1.0 omega, and the maximum excitation current can reach more than 6-10A under the power supply of 12.6V storage batteries. As shown in fig. 1, the time axis is t, the ordinate I is the exciting current, fig. 1 shows the variation curve of the exciting current of a certain generator, at this stage, the exciting current is expected to reach a large value (4000mA), and due to the influence of the internal resistance of the storage battery, the amount of the stored electric energy of the storage battery, the excitation magnetic resistance of the generator during the starting period, and other factors, the excitation resistance of the generator during the starting period and the power consumption are very bad for the successful starting of the engine.
The excitation current control during the starting period of the automobile generator in the prior art is divided into four types, one type is that an early single-function voltage regulator is used, the pre-excitation current is provided by a charging indicator lamp, the application of the low-end regulator on a small-sized vehicle is less at present, the waveform of the excitation control current is shown in figure 3, the pre-excitation stage is excited by the charging indicator lamp, the current is about 160mA, the generator starts to generate electricity when running, the voltage of the output voltage of the generator on the rectifying output end of an excitation diode, namely a D + terminal, is increased along with the increase of the rotating speed, the generator enters a positive feedback stage, when the average output voltage of the generator reaches a set value after the generator generates electricity, the generator enters a voltage regulation stage. The second is that as long as the ignition switch of the automobile engine is turned on, the excitation current reaches about 4A (taking 12V as an example), and the excitation resistance is large. As shown in figure 1, a time axis is t, an ordinate I is exciting current, figure 1 shows a change curve of the exciting current of a certain generator, the exciting current is expected to reach a large value (4000mA) at the stage, the pre-exciting current is controlled by duty ratio at the third stage, the pre-exciting current is divided into two types, namely, 22-32% pre-exciting duty ratio, and the pre-exciting current reaches 0.8-1.5A at the moment, as shown in figure 2, the exciting current appears in a pulse mode at the pre-exciting stage, compared with the second phase, although the pre-exciting current is reduced, the low-speed stage still has an invalid power generation period, consumes energy, increases the unsmooth factor of running at the low-speed stage, and normal voltage regulation can occur only when the generator is started successfully. 12-18% pre-excitation duty ratio, wherein the pre-excitation current reaches 0.3-0.8A, the electric energy of the storage battery is consumed during the starting period, namely, as long as the automobile key is opened, the generator rotor winding is electrified even when the engine is not started, unnecessary consumption is caused, electromagnetic resistance moment still exists during starting, intelligent control is insufficient, control precision is low, and optimization cooperation of a whole automobile power electronic system is not facilitated. And the fourth method is that under the condition that the excitation current of the indicator light of the generator is insufficient, the generator regulator of some vehicle types adopts a remedial design, a power supplementing circuit is designed, when the regulator is activated by a terminal or an indicator light, the situation that the pre-excitation current is insufficient through an additionally arranged power supplementing path occurs, generally, the pre-excitation current is supplemented to the single-function regulator, the waveform of the excitation current is as shown in figure 4, and if the power supplementing circuit is not available, the excitation current in the pre-excitation state is very low, for example, 80mA in figure 4, and the generator cannot be normally activated to enter the self-excitation regulation state. Under the condition of power supplement, the pre-excitation current reaches 200mA, the generator rapidly enters a positive feedback stage, the output voltage of the generator rapidly reaches a set value, and then the generator enters a mediation stage. The method also has the problems of electromagnetic resistance moment during starting, insufficient intelligent control, low control precision and unfavorable optimization and cooperation of the whole vehicle power electronic system.
Therefore, there is a need for the creative development of advanced automobile generators which can overcome the above technical defects in whole or in part, in order to achieve better performance and better control accuracy and efficiency.

Detailed Description
In order to meet the technical requirements of advanced automobile manufacturing industry, the automobile generator can intelligently output with energy conservation and high efficiency, reduce heating, improve the operation reliability and prolong the service life, the technical scheme of the invention provides an intelligent automobile generator pre-excitation current rotating speed response energy-saving control method.
Example 1
The embodiment provides an intelligent automobile generator pre-excitation current rotating speed response energy-saving control method which is applied to an automobile with an electronic control system. In the conventional automobile generator, a certain value of pre-excitation current is generally adopted to provide excitation for a self-generator, the excitation current becomes running resistance as the generator is driven, during the starting period of the generator, the resistance load of the starter is heavy, the fluctuation of the rotating speed is large in the stage before the successful starting, and the resistance moment generated by the generator under the excitation of the pre-excitation current increases the burden of the starter. According to the defects, in order to optimize the generator pre-excitation method, the electronic control system described in the embodiment includes an engine Crankshaft rotation speed sensor (CKP-crank shock position sensor) and an electronic control unit ecu (electronic control unit), and the technical scheme of the embodiment further includes, with reference to fig. 5 and 6: an electronic control unit ECU (shown as 200 in figure 6) monitors signals of an engine crankshaft rotating speed sensor of an automobile according to CKP (shown as 100 in figure 6), obtains real-time rotating speed signals of an engine crankshaft, and obtains the ratio relation between the engine crankshaft rotating speed Vcr and the automobile generator rotating speed Valt according to the diameter of an engine crankshaft pulley and the diameter of an automobile generator pulley in design parameters of the automobile to calculate the rotating speed value of a generator; when the ignition switch K1 is turned on but the engine is not started, the crankshaft stops rotating, CKP has no rotating speed signal, and the exciting current is designed as follows: before the time t1, when the calculated automobile generator rotation speed Valt is lower than the first rotation speed value V1 (for example, set as 950RPM), which includes the period when the engine is not running and the engine is in the starting stage but the engine starting rotation speed is low, the electronic control unit ECU determines the starting condition based on the calculation and outputs a first signal to control the excitation current of the generator (ALT) excitation winding L1 to be 0 through the generator voltage regulator REG (shown as 300 in FIG. 6) so as to close the excitation energy consumption in the low-speed starting process, improve the starting performance, reduce the unnecessary pre-excitation magnetic resistance moment, reduce the power consumption of the storage battery, and enable the effective energy during the starting to be applied to the starting engine as much as possible.
When the Valt rotating speed of the automobile generator is calculated to be higher than a first rotating speed value V1 but lower than a second rotating speed value V2 according to the ratio relation of Vcr and Valt, the ECU judges that the starting is successful and outputs a second signal at the time of t1, the signal controls the exciting current to be a first exciting current value I1 through a generator voltage regulator (for example, the duty ratio is set to be 10%, the exciting current is about 300 mA), and the value can be determined according to design parameters of the generator, such as the pole number, the pole gap of a fixed rotor, the number of turns of a rotor winding, the direct current resistance value and the like, so that the excitation reliability and the energy conservation are ensured.
When the rotating speed of the generator of the automobile is calculated to be higher than a second rotating speed value V2(V2 is more than V1, such as 1600RPM) along with further increase of the rotating speed of the generator, the electronic control unit ECU outputs a second signal to control the exciting current to adjust the equivalent value I2 in real time through the voltage regulator of the generator, the second signal enables the generator to quit the limitation of duty ratio excitation controlled by the first signal, because the generator speed has risen above the higher value V2, the engine has started to go from the start-up success to the idle speed or the operating condition above the idle speed, and under the condition that the engine has the ability to output larger mechanical power enough to drive various power loads, the generator is quickly separated from the initial control state of the restricted exciting current and is quickly converted into a normal generating regulation state, the exciting duty ratio at the moment is completely controlled by the output voltage feedback of the generator, and the exciting duty ratio is allowed to be regulated between 0 and 100 percent according to the output voltage feedback of the generator. The first excitation current value I1 is called an "excitation cut-in value" and is used for providing necessary excitation current for the excitation winding to wake up the excitation magnetic field, and the first rotating speed value V1 is a "wake-up excitation cut-in rotating speed"; the second rotation speed value V2 is the "full-regulation excitation cut-in rotation speed". By the detailed optimization and improvement design of the generator exciting current control method for the transition period from starting to stable running before the engine reaches normal running, the control of the generator exciting current is more suitable for the real-time working condition of the engine, the successful starting, stable running and power saving of the engine are facilitated, the service life of the starter is prolonged, and the optimal control of the generator is facilitated.
Further, on the basis of the various intelligent automobile generator pre-excitation current rotating speed response energy-saving control methods, a plurality of intermediate excitation current values which are increased from V1 to V2 in steps can be configured between the first rotating speed value V1 and the second rotating speed value V2, so that the resistance torque response of the generator can be flexibly optimized, for example, the resistance torque response can be divided into 16 duty ratio steps, the resistance is smooth and soft, duty ratio data between V1 and V2 can be calculated by the ECU according to CKP, the data are transmitted to a generator regulator, and excitation smooth control is completed by the regulator.
Further optimally, the first rotating speed value can be preferably V1 to 1000RPM according to the vehicle generator parameter characteristics, and is selected to be 1050 RPM.
Further optimally, on the basis of the intelligent automobile generator pre-excitation current rotating speed response energy-saving control method, the generator voltage regulator also monitors the phase signal voltage Ps of the generator stator winding in real time, and identifies that the rotating speed equivalent value of the phase signal voltage Ps reaches the first rotating speed value V1, and when the second signal output by the electronic control unit ECU is abnormal and lacked, the generator voltage regulator controls the excitation current to be the real-time regulation equivalent value I2, so that the normal power generation regulation of the generator is sequentially ensured, the signal failure protection is realized, and the reliability is improved.
The electronic control unit ECU and the generator voltage regulator can adopt duty ratio signals for transmission and can also adopt Lin signals for data transmission.

The embodiment of the invention can be read, and the technical scheme of the invention has the following beneficial effects: the ECU and the excitation winding are used for carrying out accurate excitation signal configuration, and pre-excitation current intelligent control is adopted, so that on one hand, the invalid excitation loss is reduced, on the other hand, the temperature rise of a power device is reduced, the thermal load of a voltage regulator of the generator is reduced, the effect is improved, the high-efficiency cooperation of the intelligent integrated control degree of the whole automobile is facilitated, and the technical requirement of a high-precision control system in the field of automobile intelligent control is met.
