When the real vehicle test is adopted, the upper computer 1 can send an actual measurement instruction to the virtual simulation platform 2, the virtual simulation platform 2 generates a conduction instruction corresponding to the storage battery sensor changeover switch 39 according to the received actual measurement instruction, the storage battery sensor changeover switch 39 is controlled to be conducted through the I/O board card 24, or the upper computer 1 sends the actual measurement instruction to the energy management controller 31 through the virtual simulation platform 2, the energy management controller 31 controls the storage battery sensor changeover switch 39 to be conducted, and after the storage battery sensor changeover switch 39 is conducted, the storage battery 37 can be used for testing.
Specifically, the storage battery 37 supplies power to the electronic load 38, the electric quantity of the storage battery 37 decreases with the consumption of the electronic load 38, the energy management controller 31 collects real state information of the storage battery 37 in real time through the EBS36, and when the real state information of the storage battery 37 meets a set condition, the energy management controller 31 generates a corresponding motor control instruction to control the state of the real generator 33, where the real state information of the storage battery 37 mainly includes the voltage, the current, the temperature, and the current remaining electric quantity of the storage battery 37.
For example, when the remaining capacity of the battery 37 is less than the capacity threshold, the energy management controller 31 controls the driving motor 34 to rotate the real generator 33, so that the real generator 33 generates power to charge the battery 37, and when the remaining capacity of the battery 37 is greater than or equal to the capacity threshold, the energy management controller 31 controls the driving motor 34 to stop rotating, so as to control the real generator 33 to stop generating power. When the remaining capacity of the battery 37 is smaller than the capacity threshold, it is determined whether the energy management controller 31 is normal by detecting whether the energy management controller 31 controls the driving motor 34 to rotate the real generator 34. Note that, when the actual measurement test is used, the generator controller changeover switch 35 and the battery sensor changeover switch 39 need to be turned on simultaneously.
On the basis of the foregoing embodiment, referring to fig. 4, the energy management control 31 is specifically configured to generate a corresponding generator control instruction according to the received real state information of the storage battery 37 and the retrieved real state information of the real generator 33, control the real generator 33 through the generator controller 32 so that the electric energy generated by the real generator 33 meets the electric quantity threshold of the storage battery 37, and send the generator control instruction to the upper computer 1 through the real-time processor 21 so that the upper computer 1 evaluates the energy management controller 31 according to the received generator control instruction.
The specific process of the actual vehicle test has been described above, and reference may be made to the above embodiments specifically, which are not described herein again, and the electric quantity threshold may also be set according to actual needs, and the embodiments are not limited.
On the basis of the above embodiment, with continued reference to fig. 4, the virtual simulation platform 2 further includes: a fault injection board 25;
the fault injection board card 25 is respectively connected with the I/O board card 24 and the energy management controller 31;
the real-time processor is further configured to transmit the generated fault condition of the energy management controller 31 to the fault injection board 25 through the I/O board 24;
the fault injection board 25 is configured to generate a fault signal corresponding to the fault condition, and send the fault signal to the energy management controller 31;
the energy management controller 31 is further configured to control a virtual generator in the simulation scene or a real generator 33 in the energy management device 3 to be tested according to the fault signal;
and the real-time processor is also used for recovering the state of the virtual generator or the real generator 33 and carrying out fault detection on the energy management controller 31 according to the state.
Specifically, the fault injection board 25 is connected to the I/O board 24 and the energy management controller 31 through a hard wire, and since the virtual simulation platform 2 can supply power to the energy management controller 31 through the I/O board 24, fault detection can be performed on power supply, signal communication, and the like of the energy management controller 31. Specifically, during testing, the upper computer 1 sends fault voltage to the real-time processor 21, the real-time processor 21 generates corresponding fault conditions according to the fault voltage and transmits the fault conditions to the fault injection board 25 through the I/O board 24, and the fault injection board 25 generates corresponding fault signals according to the fault conditions and sends the fault signals to the energy management controller 31, so that the energy management controller 31 controls the state of the virtual generator or the real generator 33 under the action of the fault signals.
For example, assuming that the normal operating voltage of the energy management controller 31 is 8V to 12V, the fault voltage is 7.5V, the current test is a simulation test, and the remaining power of the virtual battery is less than the power threshold, under normal conditions, when the signal communication is normal, the energy management controller 31 cannot normally operate, that is, the virtual generator cannot generate power, and if it is currently detected that the energy management controller 31 can still control the virtual generator to generate power under the action of the fault voltage, it indicates that the voltage of the energy management controller 31 is abnormal, and a fault exists. In the embodiment of the present invention, on the basis of the above embodiment, the fault injection board 25 is added between the I/O board 24 and the energy management controller 31, so that the energy management controller 31 can be tested for fault conditions such as voltage or current abnormality. Of course, the generator controller 32, the EBS36, and other devices may also be tested for fault conditions, and the specific process is similar to that of the energy management controller 31, and will not be described herein again.
On the basis of the above embodiment, this embodiment can both realize the switching of simulation test and actual measurement test, can compensate the unable dangerous operating mode of test or unable activation of relevant trouble such as line fault or because the defect of using the unable circumstances such as low temperature of real battery of actual measurement test again through simulation test, can also inject the fault test of the condition such as power supply anomaly, signal communication through the trouble integrated circuit board, increased test coverage and test depth for the test is more comprehensive. In addition, the interaction of the upper computer, the virtual simulation platform and the energy management device to be tested is utilized, so that the test can be continuously operated for hours under the unmanned condition, the test report and the log can be automatically generated, repeated and tedious work of testers is not required, and the test efficiency is improved.
