Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.In addition, if below in described each embodiment of the present invention involved technical characteristic do not form conflict each other and just can mutually combine.
As shown in Figures 2 and 3, illustrated system comprises electrical generator, the electrical generator belt wheel 2 be connected with driving engine, power-transfer clutch 1, car speed sensor, storage battery SOC sensor, clutch controller and clutch control actr.Electrical generator is connected by power-transfer clutch 1 with electrical generator belt wheel 2, and power-transfer clutch 1 comprises driving disc spacing pressing 3 and clutch plate 4, wherein driving disc spacing pressing 3 and electrical generator band, and 2 coaxially connect, and clutch plate 4 is connected with generator coaxle.Driving disc spacing pressing 3 is electrically connected with clutch control actr by induction coil 5.Car speed sensor is arranged between the change-speed box of automobile and axle drive shaft, and storage battery SOC sensor setting is on storage battery.Storage battery is that the ECU control unit of automobile and clutch controller are powered.The mouth of storage battery SOC sensor is connected with clutch controller, the mouth of car speed sensor is electrically connected with ECU control unit, ECU control unit is connected by CAN network with clutch controller, the vehicle speed signal of car speed sensor collection can be passed to clutch controller, by this annexation, realize the monitoring of clutch controller to accumulator electric-quantity and the speed of a motor vehicle.The mouth of clutch controller is connected with clutch control actr, realizes the control to power-transfer clutch.
As shown in Figure 1, whether the vehicle speed signal that collects according to car speed sensor and storage battery SOC sensor of clutch controller and accumulator electric-quantity signal carry out electrical generator and to generate electricity the control whether i.e. electrical generator and electrical generator belt wheel depart from.
When storage battery SOC sensor detects accumulator electric-quantity lower than calibration value, no matter vehicle is in any driving cycle, and clutch controller all controls electrical generator and all generates electricity.
When storage battery SOC sensor detects accumulator electric-quantity higher than calibration value, whether clutch controller only controls electrical generator according to vehicle speed signal and generates electricity.Now, if when vehicle is in idling, any one at the uniform velocity, in acceleration mode, clutch controller controls electrical generator and does not generate electricity, this signal is input in clutch control actr by clutch controller, clutch control actr is not powered to the induction coil of clutch driving case, and clutch driving case magnetic force disappears, and clutch plate is separated with driving disc spacing pressing, electrical generator and electrical generator belt wheel depart from, thus stop generating.If when vehicle is in deceleration regime, clutch controller controls electrical power generators, this signal is input in clutch control actr by clutch controller, clutch control actr is powered to clutch driving case, clutch driving case produces magnetic force by electromagnetic induction, adsorbs clutch plate thus drive electrical generators running.
Mode above by electromagnetism the suction-combining force control clutch is only this case example, this concrete mode is not limited in practical application, anyly accept control signal, and the master and slave Moving plate of power-transfer clutch can be realized carry out engaging and the actr of separating action all can adopt at this.
The above, be only the specific embodiment of the present invention, it should be pointed out that any those of ordinary skill in the art are in the technical scope disclosed by the present invention, the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
