Description
Technical field:
The present invention, relates to a kind of automobile when engine low-idle, can make the voltage regulator that automobile current generator steadily generates electricity.It is applicable to each passenger car electromotor, Yi Jinong, woods, herds wind-driven generator, the field such as agricultural vehicle electromotor and engineering special purpose vehicle electromotor.
Technical background:
Nowadays nearly all having electromotor, automobile current generator great majority in each automobile, tractor (IC engine car) is all AC rectification electromotor.Owing to the rotor of alternating current generator is rotated by belt drives by electromotor, its rotating speed changes with the change of engine speed, time be often accompanied by the idle situation of automobile engine, and the speed ratio of generally electromotor and alternating current generator can be between 1.5～3, therefore the rotation speed change scope of alternator rotor is the biggest, and the electromotive force that electromotor produces is directly proportional to rotor speed, magnetic flux etc., so the output voltage of electromotor will necessarily increase along with the increase of rotating speed.But the equipment such as vehicle-mounted electrical equipment (including accumulator) all need a stable and clean power environment, so, can provide for one that to stablize clean power supply be necessity so the moment；General mobile generator has 14V series and 28V series two kinds, and its output voltage range of both electromotors would generally be at 14 ± 0.2V and 28 ± 0.3V.Needing burning voltage to power to meet vehicle-mounted electrical equipment, make output voltage kept stable under all operating modes of electromotor of alternating current generator, alternating current generator is necessary for one efficient, stable voltage regulator of adapted could meet requirement.
At present the internal circuit of voltage regulator for automobile have use discrete device, (single-chip) of special IC, other components and parts of micro processor combination etc. several frequently seen circuit, it enables to the magnitude of voltage that electromotor output accuracy is higher and Wen Bo is less, can also include such as DAC, flash storage circuit etc. simultaneously, battery and the reference data of power supply and cell voltage, generator speed can be stored, and monitor and adjust battery condition, output in real time, whether have the situations such as abnormal.
Such as successive dynasties voltage regulator, there will be when engine low-idle can not be for vehicle mounted electrical apparatus and storage battery power supply or the situation of charging.Such as one automobile is when waiting traffic lights, driver would generally unclamp gas pedal makes engine low-idle run, it is ready that stepping on throttle again does " idle work " by electromotor almost without people, because pedal of stepping on the throttle need not be further continued for when car stops at all, not only oil consumption but also acceleration motor mechanical wear unhelpful to electromotor again, so (if the voltage regulator chatted on Shi Yonging) electrical power generators is not enough or does not produce electricity, make do not have enough electricity to be supplied to vehicle-mounted miscellaneous equipment or electrical appliance uses, the most vehicle-mounted electrical equipment will the electricity of battery consumption to meet the properly functioning of electrical appliance.Therefore while being desirable to voltage regulator for automobile above-mentioned functions to be had, electromotor to be made also be able to when the speed of service that low idling is even lower normal, steadily generate electricity, for vehicle mounted electrical apparatus demand, solve to chat problem with this.
Summary of the invention:
In order to chat problem on solving, the present invention utilizes the composition control circuit such as single-chip microcomputer ECM and transistor, with regulate exciting current, make-and-break time, perception ambient temperature or accept Engine ECU control signal R etc. regulate control electromotor output voltage.In an exemplary embodiment, can make, for the even lower speed when engine low-idle, the method and system that automobile current generator steadily generates electricity, overcome and alleviate the shortcoming and defect of prior art discussed above.Alleviate suddenly because rotating speed raises the rush of current brought, also reduce the impact to system voltage, also reduce electromagnetic pulse intensity simultaneously and bring electromagnetic interference or the impact of vehicle-mounted electricity equipment, improve the service life of vehicle-mounted electrical equipment, overcome electromotor bad phenomenon such as generation deficiency or not generating when idle even lower speed.
