Converter work and output voltage；
Step 3, the entire car controller are passed according to work state information, the accumulator of the DC to DC converter
The collected battery tension information of sensor and the output voltage information of DC to DC converter judge the DC to DC
Whether the function of converter is normal, and the whether normal testing result of function for the DC to DC converter that will determine that out reports
Off-line test equipment.
In the step of electric vehicle DCDC off-line test methods of the present invention based on entire car controller two, the vehicle
Controller controls the DC to DC converter by the DCDC controllers and changes output voltage.
In the step of electric vehicle DCDC off-line test methods of the present invention based on entire car controller three, if direct current turns
DC converter working condition is normally and the output voltage of DC to DC converter is 13.8 volts, then judges that the direct current turns
The function of DC converter is normal.
In the step of electric vehicle DCDC off-line test methods of the present invention based on entire car controller three, if direct current turns
DC converter operating condition failures, DC to DC converter output voltage be that 12 volts and storage battery sensor acquire
The battery tension arrived is less than or equal to 12 volts, then judges the dysfunction of the DC to DC converter.
After the step of electric vehicle DCDC off-line test methods of the present invention based on entire car controller three further
Including：
Step 4, off-line test equipment send DCDC Function detection halt instructions to the entire car controller.
In electric vehicle DCDC off-line test methods of the present invention based on entire car controller, can accurately it detect
The function of the DCDC of electric vehicle, to improve the reliability of vehicle power management function.
Description of the drawings
Fig. 1 is the flow diagram of the electric vehicle DCDC off-line test methods of the present invention based on entire car controller.
Specific implementation mode
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art with reference to specification text
Word can be implemented according to this.
Electric vehicle DCDC off-line test methods of the present invention based on entire car controller, including entire car controller and
Off-line test equipment, DCDC controllers and the storage battery sensor being electrically connected respectively with the entire car controller.
Wherein, core of the entire car controller as Control of Electric Vehicles receives the data of each component transmission simultaneously
Handle and analyze accordingly, meanwhile, control instruction also is sent out to each component, to control the working condition of each component；
The off-line test equipment can send out corresponding inspection as needed and targetedly as external detection device
Instruction is surveyed, and the judgement that feedback data makes testing result can be received.
The mating setting of the accumulator of the storage battery sensor and electric vehicle, can measure the voltage of accumulator.
Control element of the DCDC controllers as DCDC, can control the working condition of DCDC, such as control
The operating mode of DCDC processed, the real-time income voltage for obtaining DCDC and the real-time output voltage for obtaining DCDC.
As shown in Figure 1, the electric vehicle DCDC off-line test methods of the present invention based on entire car controller, including such as
Lower step：
Step 101, the off-line test equipment sends the instruction of DCDC Function detections to the entire car controller.
In this step, the off-line test equipment division sends the instruction of DCDC Function detections to the entire car controller, i.e., logical
The instruction that simulation work is sent to the DCDC is crossed, in order to verify the function of DCDC.
Step 102, the entire car controller controls direct current by the DCDC controllers according to the instruction received and turns directly
Current converter work and output voltage.
In this step, according to the instruction of entire car controller, to control DCDC, (i.e. DC to DC becomes the DCDC controllers
Parallel operation) work, for example, controlling the DC to DC converter by DCDC controllers by the entire car controller changes output
Voltage.And real-time input voltage information and real-time output voltage information are had for DCDC equipment, after work.
Step 103, the entire car controller is passed according to work state information, the accumulator of the DC to DC converter
The collected battery tension information of sensor and the output voltage information of DC to DC converter judge the DC to DC
Whether the function of converter is normal, and the whether normal testing result of function for the DC to DC converter that will determine that out reports
Off-line test equipment.
In this step, the entire car controller determines the working condition of the DC to DC converter first, in this base
On plinth, further judged according to the collected battery tension information of storage battery sensor and the output voltage information of DCDC
Whether the function of DCDC is normal.
Specifically, if entire car controller determines DC to DC, converter working condition is normal, and the direct current turns straight
The output voltage of current converter is 13.8 volts, then can determine that the function of the DC to DC converter is normal, the vehicle control
The normally functioning testing result of the judgement DC to DC converter is reported the off-line test equipment by device processed.
If alternatively, the entire car controller determines that the working condition of the DC to DC converter is failure, moreover, should
The output voltage of DC to DC converter be 12 volts, it is corresponding, the collected battery tension of storage battery sensor again smaller than
Or be equal to 12 volts, then it can determine that the dysfunction of the DC to DC converter, the entire car controller will be described in the judgements
The testing result of the dysfunction of DC to DC converter is reported to the off-line test equipment.
In electric vehicle DCDC off-line test methods of the present invention based on entire car controller, if to the DCDC into
After row detection, also further the stopping of DCDC Function detections can be sent to the entire car controller from off-line test equipment and referred to
It enables.
That is, no matter DCDC function is normal or dysfunction, all can be considered and the Function detection of DCDC completed,
So, the off-line test equipment can send DCDC Function detection halt instructions to the entire car controller.
In electric vehicle DCDC off-line test methods of the present invention based on entire car controller, can accurately it detect
The function of the DCDC of electric vehicle, to improve the reliability of vehicle power management function.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and legend shown and described herein.
