Abstract
The utility model discloses a mileage increasing motorcycle current detecting circuit, the key is that the detecting circuit comprises a first resistance in series connection to an ISG (integrated starter and generator) electrical machine controller branch, a second resistance in series connection to a power supply branch and a third resistance in series to the electrical machine branch, a first operating amplifier, a second operating amplifier and a third operating amplifier are respectively connected to the ISG(Integrated starter and generator) electrical machine controller branch, the power supply branch and the electrical machine branch. The mileage increasing motorcycle current detecting circuit can realize the detection of the mileage increasing motorcycle current, thereby having the advantages of being simple in structure and convenient to measure.
Description
Technical field
The utility model relates to a kind of current detection circuit.
Background technology
The detection of motorcycle electric current plays an important role in motorcycle control, and detecting electric current, to offer controller can be to improve motorcycle control performance and motorcycle self performance.As shown in Figure 1, in the control of extended-range motorcycle, need to detect three electric currents: battery discharging electric current, generator generation current and motor current of electric.The detection of these three electric currents becomes the important part in the controller design, can guarantee safety current and the optimum current of each parts by the detection to electric current, promotes the safety and reliability of whole control.
Practical fresh content
The purpose of this utility model is to provide a kind of testing circuit that can detect extended-range motorcycle electric current.
To achieve these goals, by the following technical solutions:
A kind of extended-range motorcycle electric current detection circuit, it is characterized in that: described testing circuit comprises the first resistance of being connected on respectively ISG electric machine controller branch road, be connected on the second resistance of power branch and be connected on the 3rd resistance of motor branch road, also is connected with respectively the first operational amplifier, the second operational amplifier and the 3rd operational amplifier on ISG electric machine controller branch road, power branch and motor branch road.
The utility model has been realized the detection to the required electric current of extended-range motorcycle, provides related data to controller, guarantees its safety and reliability.
Description of drawings
Fig. 1 is extended-range motorcycle control basic circuit;
Fig. 2 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As depicted in figs. 1 and 2, a kind of extended-range motorcycle electric current detection circuit, comprise the first resistance 11 of being connected on respectively ISG electric machine controller branch road, be connected on the second resistance 22 of power branch and be connected on the 3rd resistance 33 of motor branch road, on ISG electric machine controller branch road, power branch and motor branch road, also be connected with respectively the first operational amplifier 1, the second operational amplifier 2 and the 3rd operational amplifier 3.
As in Fig. 2 institute, when the ISG motor was not worked, for just, the electrode of the second operational amplifier 2 was for bearing through the electrode of the 3rd operational amplifier 3 for the right electric current out.During electric motor starting, the electrode of the first operational amplifier 1 and the 3rd operational amplifier 3 is being for just, and the electrode of the second operational amplifier is for negative, measures A1, the A3 place namely draws the Node Current at A2 place.
When the ISG on left side motor is done generator work, can measure the electric current at A2 and A3 place, addition can draw the A1 electric current.The operational amplifier that accesses in whole metering circuit adopts single power supply in measuring process.
