Example 1
Referring to fig. 1, fig. 1 is a flow chart of a control method of an external heater according to an embodiment of the present application. The control method of the external heater comprises the following steps:
and S101, when the ambient temperature is lower than a preset ambient temperature threshold value, acquiring the actual power of the air conditioner of the warm air conditioner on the electric automobile.
S102, detecting the current air-conditioning water temperature of a warm air conditioner on the electric automobile, judging that the current air-conditioning water temperature is lower than a preset water temperature threshold, and if yes, executing a step S103; if not, the process is ended.
S103, judging whether the actual power of the air conditioner is lower than a second preset power threshold value, if yes, executing a step S104; if not, the process is ended.
In this embodiment, when the current air-conditioning water temperature is lower than the preset water temperature threshold and the actual power of the air conditioner is lower than the second preset power threshold, it is determined that the external heater is not in a working state.
In this embodiment, when the current air-conditioning water temperature is not lower than the preset water temperature threshold or the actual power of the air conditioner is not lower than the second preset power threshold, it is determined that the external heater is in a working state.
It can be understood that the vehicle starts to detect the air-conditioning water temperature and the air-conditioning power in the low-temperature environment, and when the actual power of the air-conditioning is lower than a certain value and the air-conditioning water temperature is also lower than a certain value, the external heater is judged to be not working.
S104, judging whether the actual power of the air conditioner is larger than a first preset power threshold value, if so, executing a step S105; if not, the process is ended.
S105, acquiring water temperature detection data of the warm air conditioner in a preset time period.
S106, judging whether the water temperature of the warm air conditioner is in an ascending trend along with the time according to the water temperature detection data.
S107, when the water temperature of the warm air conditioner is in an ascending trend along with the time, calculating a water temperature ascending numerical value according to the water temperature detection data; when the water temperature of the warm air conditioner is in a descending trend along with the time, if not, calculating a water temperature descending numerical value according to the water temperature detection data; the water temperature change value of the warm air conditioner comprises a water temperature rising value or a water temperature falling value.
As an alternative embodiment, the step of calculating the water temperature increase value from the water temperature detection data includes:
screening the water temperature detection data to obtain screening data;
intercepting monotonically rising temperature rise section data from the screening data;
determining a change value of the water temperature according to the temperature rise data;
and (5) calculating the increment offset of the change value of the water temperature to obtain a water temperature increment value.
As a further alternative embodiment, determining a target operating gear of the external heater according to the water temperature change value includes:
when the water temperature change value is a water temperature rising value, judging whether the water temperature rising value is abnormal or not;
if not, acquiring the temperature rise time corresponding to the temperature rise section data;
calculating the water temperature rising rate according to the temperature rising time and the water temperature rising value;
and comparing the water temperature rising rate with a preset working gear comparison table to determine a target working gear of the external heater.
As a further alternative embodiment, the method further comprises:
when the water temperature rising value is abnormal, abnormal data eliminating processing is carried out on the water temperature rising value to obtain a processed value, and a target working gear of the external heater is determined according to the processed value and a preset working gear comparison table.
S108, judging whether the water temperature change value is abnormal, if so, executing steps S112 and S113; if not, steps S109 to S111 and S113 are executed.
S109, acquiring water temperature change time corresponding to the water temperature change data.
S110, calculating the water temperature change rate according to the water temperature change time and the water temperature change data.
S111, comparing the water temperature change rate with a preset working gear reference table, and determining a target working gear of the external heater.
For example, the method processes the water temperature rise value when the air-conditioning water temperature rise is detected. In practice, however, the air-conditioning water temperature fluctuates up and down; therefore, it is necessary to screen the rising of the air-conditioning water temperature, intercept the monotonically rising temperature rise section for processing, and increase the deviation of the water temperature change value to obtain an effective water temperature rising value. After that, the method can obtain an effective water temperature rising value, and can perform similar treatment on the rising time, so that the monotonically rising temperature rising time can be intercepted, and then the effective water temperature rising rate is obtained by the effective water temperature rising value and the effective time. Finally, the effective water temperature rising rate can be obtained through calculation, and then table lookup is performed under different environment temperatures, so that the corresponding working gear of the external heater is obtained.
S112, carrying out abnormal data elimination processing on the water temperature rising value to obtain a processing value, and determining a target working gear of the external heater according to the processing value and a preset working gear comparison table.
S113, controlling the external heater to work according to the target working gear.
In this embodiment, the execution subject of the method may be a computing device such as a computer or a server, which is not limited in this embodiment.
In this embodiment, the execution body of the method may be an intelligent device such as a smart phone or a tablet computer, which is not limited in this embodiment.
Therefore, by implementing the control method of the external heater described in the embodiment, the working gear of the heater can be automatically adjusted, the control efficiency is high, and accordingly energy consumption generated when the heater is started is reduced, and waste of electric energy is avoided.
