Description of the drawings
Fig. 1 is the flow diagram of the quick discharge function off-line test method of the present invention based on electric machine controller.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to enable those skilled in the art with reference to specification text
Word can be implemented according to this.
In quick discharge function off-line test method of the present invention based on electric machine controller, set including off-line test
Standby, electric machine controller and motor busbar voltage sensor.
Wherein, the off-line test equipment is external equipment, is the combination of hardware and software, passes through the off-line test
Equipment can realize the reception processing to data-signal, and export corresponding handling result.
The electric machine controller is the core component for carrying out the motor of electric vehicle control, in of the invention, the motor
The voltage detecting that prestored in controller algorithm routine can obtain the voltage signal that motor busbar voltage sensor senses,
And can test to the voltage signal got, in order to judge whether vehicle voltage is full according to the height of voltage signal
Sufficient safety requirements.
The motor busbar voltage sensor is used for detection-sensitive motor busbar voltage.
As shown in Figure 1, the quick discharge function off-line test method of the present invention based on electric machine controller, performs such as
Lower step：
Step 101, the off-line test equipment sends the instruction for reading motor busbar voltage to the electric machine controller.
In this step, the off-line test equipment is connect with the electric machine controller, and can be to the electric machine controller
Under send instructions, for example, to the electric machine controller send read motor busbar voltage instruction.
Step 102, the electric machine controller sends out reading electricity according to described instruction to the motor busbar voltage sensor
Machine busbar voltage solicited message, the motor busbar voltage sensor are fed back according to the solicited message to the electric machine controller
Motor bus voltage value.
In this step, the electric machine controller is connect with the motor busbar voltage sensor, and can be to motor busbar electricity
Pressure sensor sends out request, the motor busbar voltage sensor to be required to feed back to the motor bus voltage signal sensed
Electric machine controller.
Step 103, the electric machine controller judges whether to meet safety requirements according to the motor bus voltage value of feedback, and
Corresponding safety value mark is fed back to the off-line test equipment.
Specifically, electric machine controller safe voltage value according to as defined in industry examines motor busbar voltage
It surveys namely judges current vehicle voltage whether in safe range.So, if motor bus voltage value is higher than scheduled peace
Full voltage value, then the electric machine controller is judged as not meeting safety requirements, and is unsatisfactory for off-line test equipment feedback
Safety value mark.If motor bus voltage value is less than scheduled safe voltage value, the electric machine controller is judged as meeting peace
Full requirement, and meet safety value mark to off-line test equipment feedback.In other words, for service personnel, only
Motor bus voltage value is less than scheduled safe voltage value, just means the voltage detecting success to motor busbar, conversely, then anticipating
Taste the voltage detecting failure to motor busbar.But the result of voltage detecting failure is apparently not the purpose detected, then,
Electric machine controller can repeat the detection of motor busbar voltage, until electric machine controller judges motor bus voltage value less than pre-
Fixed safe voltage value, and finally meet safety value mark to off-line test equipment feedback.
In quick discharge function off-line test method of the present invention based on electric machine controller, electric machine controller is utilized
The motor busbar voltage of motor busbar voltage sensor sensing is judged, to determine whether current vehicle voltage meets dimension
Requirement is repaiied, the excessively high security risk that harm is brought to maintenance personal of vehicle voltage can be effectively eliminated.
Although the embodiments of the present invention have been disclosed as above, but its be not restricted in specification and embodiment it is 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, it is of the invention and unlimited
In specific details and legend shown and described herein.
