Description

A kind of test macro of measuring new-energy automobile power drive system efficient
Technical field
The utility model relates to a kind of test macro of measuring new-energy automobile power drive system efficient.
Background technology
Power drive system efficient is a very important reference data of design of electrical motor.Power drive system efficient=output power/power input.At present, the measurement of the output power of new-energy automobile power drive system mainly is that dynamometer machine is linked to each other by spring coupling with motor, operate under the rotating speed pattern by the control dynamometer machine, the control motor operates under the torque mode, motor just can operate under the specific rotating speed and be subject to different moments of torsion like this, just can measure the output power of motor by formula, gather again input current and the input voltage of motor operation by power analyzer, obtain power input with this, so just can measure power drive system in the efficient of specific rotation speeds point and specified torque point.But this method can only be calculated by the numerical value of inputting certain specific rotating speed and moment of torsion, and what namely calculate is the numerical value of some points, is not the continuous power drive system efficient under a kind of real-time road.
The utility model content
The purpose of this utility model is to provide a kind of test macro of measuring new-energy automobile power drive system efficient, and this test macro can calculate the lower continuous power drive system efficient of stretch spectrum continuously.
For achieving the above object, the utility model has adopted following technical scheme: comprise PC, store the road spectrum information in the storer of PC, PC links to each other with the input end of entire car controller, the output terminal of entire car controller links to each other with the input end of Dynamometer Control device and the input end of electric machine controller respectively, the output terminal of described Dynamometer Control device links to each other with dynamometer machine, the output terminal of described electric machine controller links to each other with motor, the input end of described electric machine controller links to each other with power supply, and the output terminal of power supply links to each other with electric machine controller by power analyzer.
Dynamometer machine of the present utility model links to each other by spring coupling with motor.
Pass through the CAN bus transmissioning data between PC of the present utility model and entire car controller, electric machine controller, the Dynamometer Control device.
As shown from the above technical solution, the utility model stores the road spectrum information of standard by the storer at PC, PC is by processing the road spectrum information like this, parse corresponding real-time throttle and brake pedal information, go out torque value and tachometer value by entire car controller by real-time throttle and brake pedal information calculations again, and respectively torque value and tachometer value are passed to electric machine controller and Dynamometer Control device, electric machine controller and Dynamometer Control device be drive motor and dynamometer machine rotation respectively, at this moment can calculate according to formula the output power of power drive system, calculate again the power input of power drive system by power analyzer, get the power drive system efficient of a point in the outlet spectrum, the power drive system efficient that the lower whole process of motor of this road spectrum is had a few can be calculated continuously by PC by same this system, and is the power drive system efficient under a kind of real-time road.
Description of drawings
Fig. 1 is system chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of test macro of measuring new-energy automobile drive motor efficient as shown in Figure 1, comprise PC 1, store the road spectrum information in the storer of PC 1, PC 1 links to each other with the input end of entire car controller 2, the output terminal of entire car controller 2 links to each other with the input end of Dynamometer Control device 3 and the input end of electric machine controller 4 respectively, the output terminal of described Dynamometer Control device 3 links to each other with dynamometer machine 5, the output terminal of described electric machine controller 4 links to each other with motor 6, described electric machine controller 4 links to each other with power supply 7, the output terminal of power supply 7 links to each other with electric machine controller 4 by power analyzer 8, and dynamometer machine 5 and motor 6 link to each other by spring coupling.Transmit data by the CAN bus between PC of the present utility model and entire car controller, electric machine controller, the Dynamometer Control device.
Concrete method of testing is as follows:
The hardware-in-loop simulation system software is installed on this PC, and concrete grammar is as follows:
At PC the hardware-in-loop simulation system software is installed, reads first the standard road spectrum information spectrum information that satisfies the need again by this software and process, draw corresponding real-time throttle and the information of brake pedal; The real-time throttle that PC will draw again and the information of brake pedal feed back to entire car controller, calculate respectively tachometer value and torque value by entire car controller; Entire car controller sends to the Dynamometer Control device with tachometer value by the CAN bus again, Dynamometer Control device control dynamometer machine is worked under the rotating speed pattern, entire car controller sends to electric machine controller with torque value by the CAN bus, the motor controller controls motor is worked under torque mode, because dynamometer machine links to each other by elasticity connection connected device with motor, so just be equivalent to dynamometer machine and be subject to specific torque by motor stabilizing under certain specific rotating speed this moment, just can calculate the output power of power drive system according to this rotating speed and torque, that is: output power=torque * rotating speed/9550, power analyzer collects input current and the input voltage of power supply simultaneously, calculate again the power input of power drive system by input current and input voltage, that is: power input=voltage * electric current, so just can obtain the efficient of power drive system, that is: efficient=output power/power input, this only is one of them point, by the processing to whole road spectrum information, just can obtain the power drive system efficient of having a few under this road spectrum information, and be a kind of real-time power drive system efficient, again the efficient of having a few is processed, then drawn out the efficiency curve of this power drive system under this road spectrum.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
