Effect, below in conjunction with accompanying drawing and preferred embodiment, to according to the detailed description of the invention of the present invention, structure,
Feature and effect thereof, after describing in detail such as.
First embodiment
The flow chart of the temperature protecting method that Fig. 1 provides for first embodiment of the invention.As it is shown in figure 1,
Described temperature protecting method includes:
Step S11: monitoring motor, to gather the temperature data of motor；
Wherein, motor can be, but not limited to as electromotor or traction electric machine.
Specifically, the frequency of the temperature data gathering motor can be, but not limited to as every 10 microsecond collections
Once.
Step S12: judge that whether the number of times of collecting temperature data is equal to the first preset value；
Wherein, the first preset value is that user presets the number of times of the temperature data of collection as required
Numerical value.First preset value can be, but not limited to be 128 times.
Step S13: if the number of times of collecting temperature data is not equal to the first preset value, then return monitoring motor,
To gather the step of the temperature data of motor；
