This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Example one
Referring to fig. 1, a first embodiment of the present invention is directed to a calibration method for calibrating an air conditioning system of a vehicle through a calibration device, where the method includes steps S10-S40:
step S10, acquiring working condition information of a vehicle in a working state through a preset working condition sensor, and sending the working condition information to an air conditioner controller of the air conditioning system;
in the present embodiment, the preset condition sensor includes, but is not limited to, a PTC sensor, a sunlight sensor, a vehicle running speed sensor, an ambient temperature sensor, a voltage sensor of an on-vehicle battery, an in-vehicle temperature sensor, a radiator fan operating voltage or rotation speed sensor, an evaporator surface temperature sensor, an air conditioner blower operating voltage or rotation speed sensor, and an air conditioner blower operating voltage or rotation speed sensor.
The working condition sensor is used for acquiring the working condition information of the automobile in a working state, and after the working condition information of the automobile is acquired, the working condition information of the automobile is sent to an air conditioner controller of an air conditioning system.
Step S20, temperature information of a vehicle air conditioning system in a working state is obtained through a temperature sensor preset in the vehicle, and the temperature information is sent to the air conditioning controller;
in this embodiment, the temperature sensors preset in the vehicle include, but are not limited to, an air outlet temperature sensor disposed at an air outlet of the air conditioner, a breathing position temperature sensor disposed at a breathing position of a passenger, shoulder temperature sensors disposed on two sides of a shoulder of a passenger in the front row, and a foot temperature sensor disposed at a foot of the passenger.
The air outlet temperature sensor is required to be arranged in the centers of all air duct outlets connected with the front air conditioner, extends into the air duct by 1-2 cm and is not contacted with any part in the air duct. The breathing temperature sensor is arranged at the breathing position of the passenger, the specific position is determined according to the internal structure of the target vehicle type, and at least the left and right seats of the first row and the second row (without the middle seat of the rear row) are ensured to be arranged. The shoulder temperature sensors are mounted on the shoulders of the left and right seats of the first and second rows (without the middle seat of the rear row), and the specific positions depend on the internal structure of the target vehicle type. The foot position temperature sensor is arranged at about 5cm of the plane of the ground floor, the specific position is determined according to the internal structure of a target vehicle type, and the foot position temperature sensor is difficult to step on the premise of approximately reflecting the temperature near the feet of passengers to the greatest extent.
The temperature sensor is used for acquiring the temperature information of the air conditioning system of the automobile in a working state, and after the temperature information of the air conditioning system of the automobile is acquired, the temperature information of the air conditioning system of the automobile is sent to the air conditioning controller of the air conditioning system.

And step S50, based on the calibration data, sending a calibration instruction to the air conditioning system through the air conditioning controller, so that the air conditioning system is calibrated according to the calibration instruction.
After the calibration data are obtained, a calibration instruction for calibrating the air conditioning system is generated according to the calibration data, and the calibration instruction is sent to the air conditioning system through the air conditioning controller, so that the air conditioning system is calibrated according to the calibration instruction.
In one example of the invention, the PWM control mode is adopted for the wind/water PTC of the heating system of the pure electric vehicle, so that the method has a very important effect on improving the comfort level of an automatic air conditioner and can be equivalent to the engine water temperature control of the traditional vehicle type.
In the air conditioner calibration method shown in this embodiment, the restriction requirements are made on the road test calibration working conditions in spring and autumn, summer and winter and each temperature point, and according to different environmental temperatures and sunlight radiation intensities, the calibration method specifies 3 different winter environmental working conditions, 3 different summer environmental working conditions and 2 different spring and autumn environmental working conditions. The above environmental conditions are shown in table 1:
TABLE 1
| Working condition number | Ambient temperature | Intensity of sunlight | Corresponding to seasons |
| 1 | -15～5℃ | 0～300W/m2 | Winter season |
| 2 | -5～5℃ | 0～400W/m2 | Winter season |
| 3 | 5～15℃ | 0～500W/m2 | (Summer) |
| 4 | 25～30℃ | 0～1000W/m2 | (Summer) |
| 5 | 30～35℃ | 0～1000W/m2 | (Summer) |
| 6 | 35～40℃ | 0～1000W/m2 | (Summer) |
| 7 | 15～20℃ | 0～600W/m2 | Spring and autumn |
| 8 | 20～25℃ | 0～800W/m2 | Spring and autumn |
Since the ambient temperature and the solar radiation intensity are fluctuated and uncontrollable during the road test, the specification of the air conditioner calibration method shown in the embodiment on the environmental parameters is embodied in an interval form. The intensity of the solar radiation is based on the solar radiation power received per square meter on the ground plane (of the place where the vehicle is located).
For the working conditions of 5-15 degrees in winter and 30-35 degrees in summer in table 2, road experiments should be performed in the south wet-cold and north dry-cold areas and the south wet-hot and north dry-hot areas respectively as far as possible.
For winter, summer, spring and autumn, the calibration method stipulates 3 different air conditioner settings respectively, as shown in table 2:
TABLE 2
| Winter setting | 21℃ | 24℃ | 27℃ |
| Summer setting | 19℃ | 22℃ | 25℃ |
| Spring and autumn settings | 21℃ | 23℃ | 26℃ |
Therefore, the road experiment comprises 24 experimental cases, and for each working condition point, the urban road condition experiment and the high-speed road condition experiment are required to be carried out. The details are as follows:
urban road condition experiment: driving on an urban road at a speed of not more than 60 km/h; or the vehicle is driven in a mode of stopping for 0.5-2 minutes at the idle speed of every 500 meters to simulate the condition that the vehicle frequently passes through a traffic light intersection under urban road conditions, and the driving time is not less than 30 minutes. If conditions permit, cold start should be guaranteed as much as possible.
High-speed road condition experiment: the vehicle runs on the expressway at the speed of 90-130 km/h, and the running time is not less than 30 minutes. There is no need to guarantee a cold start.
The two experiments can be carried out independently or jointly.
In view of the uncontrollable road test environment, if the vehicle speed occasionally fails to meet the requirement in the high-speed road condition experiment, the experiment is still effective.
The routine road experiment included 24 cases in total, as shown in table 3:
table: 3
In order to improve the calibration accuracy, each case needs to perform at least 6 urban road condition experiments and 6 high-speed road condition experiments, and at least 144 urban road condition experiments and 144 high-speed road condition experiments are summed.
