Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. Where the following description refers to reference numerals, the same reference numerals in different embodiments refer to the same or similar elements unless otherwise indicated.
The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of structures consistent with certain aspects of the invention, as detailed in the appended claims.
An embodiment of the present application provides an air conditioner operation control method, and referring to fig. 1, the method includes:
and S101, obtaining basic parameters according to the target temperature, the temperature in the vehicle and the ambient temperature.
For example, in an implementation manner of the embodiment of the present application, the ambient temperature is an outdoor temperature of the vehicle, and the target temperature is a target temperature to be reached by an indoor temperature set in advance by a user. The base parameters may be derived by a specific algorithm.
And S102, determining operation parameters corresponding to the operation mode according to the basic parameters, wherein the operation parameters corresponding to the operation mode comprise an internal and external circulation mode, a blowing mode, a blower mode, a compressor opening and closing state, a compressor target rotating speed, a vehicle-mounted heater opening and closing state and a vehicle-mounted heater target rotating speed.
For example, in one implementation of the embodiments of the present application, a corresponding table may be established between different basic parameters and an internal circulation manner, an air blowing mode, an air blower mode, an on-off state and target rotation speed of the compressor, an on-off state and target power of the vehicle heater, and the basic parameters within a certain threshold range may correspond to a set of the internal circulation manner, the air blowing mode, the air blower mode, the on-off state and target rotation speed of the compressor, or the on-off state and target power of the vehicle heater. Thus, after the basic parameters are determined, the corresponding different types of operation parameters can be obtained quickly.
And step S103, controlling the starting of the running mode of the motor corresponding to each running parameter according to the running parameters.
For example, in one implementation of the embodiment of the present application, the vehicle controller may control the ventilation motor, the blower, the compressor, and the vehicle-mounted heater through different channels, and control the operation of its corresponding motor according to each obtained operation parameter.
For example, the internal and external circulation mode, the blowing mode, and the blower gear may have a plurality of different conditions, and each condition corresponds to a basic parameter within a threshold range, for example, when the basic parameter is within a certain threshold range, the internal and external circulation mode is first, the blowing mode is first, the blower gear is first, the compressor is turned on and is at a first target rotation speed, then the vehicle controller may simultaneously control the compressor to operate at the first target rotation speed, the ventilation motor ventilates in the first internal and external circulation mode, and the blower blows in the first blowing mode and the first gear.
In addition, due to the operation of the air conditioning system, the temperature in the vehicle room can gradually approach the target temperature set by the user, the value of the basic parameter can be changed along with the change of the temperature in the vehicle room, and the corresponding internal and external circulation modes, the blowing mode, the gear position of the blower and the like can be changed in real time. Therefore, the air conditioner can better meet the requirements of users in the running process.
For example, referring to fig. 2, in an implementation manner of the embodiment of the present application, the control method may include:
step S201, a target temperature, an in-vehicle temperature, and an ambient temperature are acquired.
For example, a vehicle may be equipped with an indoor temperature sensor that monitors the vehicle's indoor temperature and an outdoor temperature sensor that monitors the ambient temperature outside the vehicle. The air conditioning system can be provided with a temperature control knob, the outer side of the temperature control knob can be provided with a temperature scale value, a user can rotate the temperature control knob by a certain angle, and the temperature control knob determines the target temperature selected by the user according to the angle.
And the method can record the target temperature selected by the user before, and if the operation of the temperature control knob by the user is not detected, the temperature selected by the user last time is taken as the target temperature of the time. The target temperature selected by the user each time is in corresponding relation with the current in-vehicle temperature and the current environment temperature, and is stored in the memory. If the user does not select the current target temperature, the previous vehicle interior temperature and the environment temperature which are closest to the current vehicle interior temperature and the current environment temperature are searched, and the target temperature corresponding to the closest vehicle interior temperature and the closest environment temperature is used as the current target temperature.
Step S202, determining a reference comfortable temperature and an external temperature compensation amount according to the environment temperature.
For example, the comfortable temperature suitable for human body is 25 ℃, but different users have different perceptions of temperature, and when the environmental temperature is different, the comfortable temperature perceived by the users is slightly different. Therefore, the user can establish the corresponding relation between the ambient temperature and the reference comfortable temperature according to different comfortable temperatures when the user is at different ambient temperatures, and the user's requirements and the user's own conditions can be better met.
In addition, different ambient temperatures can also correspond to different external temperature compensation quantities, so that the air conditioner running process can meet the requirements of users according to various parameters.
Step S203, determining a basic parameter according to the first formula.
For example, the first formula may be
Y＝A(X1-X2)+B(X1-X3)+C，
Wherein Y represents a basic parameter, A represents an in-vehicle temperature difference gain coefficient, and X1Which is indicative of the target temperature, is,
b represents a comfort temperature difference gain coefficient, X2Indicates the in-vehicle temperature, X3Denotes a reference comfort temperature, and C denotes an external temperature compensation amount.
Step S204, acquiring the corresponding relation between the basic parameters and the operation parameters corresponding to each operation mode.
For example, the operation parameters corresponding to the operation mode may include an internal and external circulation mode, a blowing mode, a blower gear, an on-off state of a compressor, an on-off state of an on-vehicle heater, a target rotation speed of the compressor, and a target power of the on-vehicle heater.
The user can establish the corresponding relation between the basic parameters and each operation parameter in advance, and after the basic parameters are determined, the corresponding internal and external circulation modes, the blowing mode, the blower gear, the compressor opening and closing state and the target rotating speed or the vehicle-mounted heater opening and closing state and the target power can be quickly determined according to the corresponding relation.
Specifically, the parameters of the internal and external circulation modes may include: 0x0, 0x1, 0x2, 0x3, 0x4, 0x5-0x7, and the like. Wherein 0x0 can represent an inner circulation, 0x1 can represent an outer circulation, 0x2 can represent that the inner circulation and the outer circulation respectively account for 50%, 0x3 can represent that the inner circulation accounts for 30%, the outer circulation accounts for 70%, 0x4 can represent that the inner circulation accounts for 70%, the outer circulation accounts for 30%, and 0x5-0x7 can be in a reserved mode, so that users can increase more inner and outer circulation modes according to their own needs.
The correspondence between the parameters of the internal and external circulation modes and the basic parameters is shown in table 1 below.
TABLE 1
Of course, the basic parameters corresponding to the parameters of the internal and external circulation modes are not limited to the above values, and in other implementation manners of the embodiment of the present application, specific values of the basic parameters corresponding to different internal and external circulation modes may be modified according to requirements of a user.
The parameters of the blowing mode may include 0x0, 0x1, 0x2, 0x3, 0x4, 0x5, 0x6-0x7, and the like. Wherein, 0x0 can represent the face blowing mode, 0x1 can represent the foot blowing mode, 0x2 can represent the face blowing and foot blowing modes, 0x3 can represent the front defrosting mode, 0x4 can represent the rear defrosting mode, 0x5 can represent the front defrosting and rear defrosting modes, and 0x6-0x7 can be reserved modes, so that users can add more air blowing modes according to their own needs.
In one implementation of the embodiments of the present application, the blower may be determined to operate in a face and/or foot blowing mode based on the base parameters, and the defrost mode may be not controlled by the automatic air conditioning system and may be manually controlled by a user, i.e., the defrost mode may be independent of the base parameters.
For example, when the front defrosting mode is started, the compressor and the vehicle-mounted heater are started simultaneously, specifically, a key switch for controlling the opening and closing of the compressor and a key switch for controlling the opening and closing of the vehicle-mounted heater can be arranged on a console of the front cabin of the vehicle room, and each key switch can be provided with a corresponding working state indicator lamp, so that a user can know the current running states of the compressor and the vehicle-mounted heater according to the on and off of the indicator lamp.
When the rear defrosting mode is started, because the rear window is far away from the front cabin, the rear window cannot be defrosted in time by using the vehicle-mounted heater and the compressor, so that the electric heating resistance wire can be arranged at the rear window, the opening and closing control of the electric heating resistance wire is arranged on the front cabin control console, and a user can directly operate the rear defrosting button switch to control the rear defrosting electric heating resistance wire to heat and start to work, thereby defrosting the rear window. Moreover, because a user can not conveniently observe the progress of the rear window defrosting operation at any time, the rear defrosting controller can be further provided with an automatic closing function, when the rear window electric heating resistance wire is opened for a certain time, the operation of the electric heating resistance wire is automatically stopped, and the phenomenon that the electric heating resistance wire is used excessively due to forgetting of the user is avoided.
The corresponding relationships between 0x0, 0x1, and 0x2 and the basic parameters can be shown in table 2 below.
TABLE 2
Of course, the basic parameters corresponding to the parameters of the blowing modes are not limited to the above values, and in other implementation manners of the embodiment of the present application, specific values of the basic parameters corresponding to different blowing modes may be modified according to requirements of a user.
Parameters for blower gears may include 0x0, 0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, and so forth. Wherein, 0x0 may indicate the automatic air conditioning system is turned off, 0x1 may indicate 1 gear, 0x2 may indicate 2 gear, 0x3 may indicate 3 gear, 0x4 may indicate 4 gear, 0x5 may indicate 5 gear, 0x6 may indicate 6 gear, and 0x7 may indicate 7 gear.
The corresponding relationship between the parameters of the blower gear and the basic parameters can be shown in table 3 below.
TABLE 3
In other implementation manners of the embodiment of the application, a user can set more blower gears according to the requirement of the user, basic parameters corresponding to the parameters of the blower gears are not limited to the numerical values, and in other implementation manners of the embodiment of the application, specific numerical values of the basic parameters corresponding to different blower gears can be modified according to the requirement of the user.
The parameters of the on-off state of the compressor may include: 0x0 and 0x1, 0x0 may indicate off, 0x1 may indicate on. The correspondence relationship between the parameters of the compressor opening/closing state and the basic parameters can be shown in table 4 below.
TABLE 4
In one implementation of the embodiment of the present application, when the value of the basic parameter is located in the range of the return difference, the on/off state of the compressor is maintained in the previous state, that is, for example, when the basic parameter Y is 120, the compressor is in the on state, and at the next time, the basic parameter Y may be 130, which is in the range of the return difference, the state of the compressor is maintained in the on state. Therefore, a certain buffering effect can be achieved, if only one threshold value is used for judging opening and closing, when the basic parameter Y continuously changes around 130, the compressor can continuously jump between opening and closing, and the compressor can be seriously damaged. Two different thresholds are respectively set for basic parameters corresponding to the opening and the closing of the compressor, so that when the basic parameters are in a return difference region between the two thresholds, the compressor can have certain buffering time when jumping between the opening and the closing.
For example, during the operation of the compressor, the basic parameter Y value is originally increased slowly in a certain trend, and a sudden sharp increase of the basic parameter Y value may occur, and then the basic parameter Y value is restored to the previous specific operation trend, so that when the basic parameter Y value is suddenly located in the range of the return stroke difference, the compressor may be kept in the previous state, if the basic parameter Y value continues to increase, the compressor may be turned off, and if the basic parameter Y value is restored to the range less than 125, the compressor may be kept in the on state.
For example, table 5 provides a corresponding set of a part of the target speed of the compressor and the value of the basic parameter Y, and fig. 4 can be obtained from table 5, and it can be seen from fig. 4 that the value of the basic parameter Y has a linear relationship with the target speed of the compressor within a certain interval.
TABLE 5
In other implementation manners of the embodiment of the present application, when the basic parameter Y is other values, the corresponding target rotation speed of the compressor can be obtained according to the linear relationship.
The parameters of the on-vehicle heater opening and closing state may include: 0x0 and 0x1, 0x0 may indicate off, 0x1 may indicate on. The correspondence relationship between the parameters of the on-vehicle heater opening/closing state and the basic parameters can be shown in table 6 below.
TABLE 6
When the vehicle-mounted heater is in the return difference interval, namely between 140 and 150, the running state of the vehicle-mounted heater is kept in the previous state, so that the damage to the vehicle-mounted heater caused by continuously opening and closing the vehicle-mounted heater when the basic parameter continuously changes around the return difference can be avoided.
In addition, table 7 provides a corresponding set of a part of the vehicle-mounted heater target power and the basic parameter Y value, and fig. 5 can be obtained from table 7, and it can be seen from fig. 5 that the basic parameter Y value may have a linear relationship with the vehicle-mounted heater target power within a certain interval.
TABLE 7
In other implementation manners of the embodiment of the application, when the basic parameter Y is other values, the corresponding target power of the vehicle-mounted heater can be obtained according to the linear relationship.
Therefore, when the basic parameter Y value is determined, the currently required internal and external circulation mode, the blowing mode, the blower gear, the compressor opening and closing state and target rotating speed or the vehicle-mounted heater opening and closing state and target power can be obtained according to the corresponding relation between the basic parameter and the internal and external circulation mode, the blowing mode, the blower gear, the compressor opening and closing state and target rotating speed, and the vehicle-mounted heater opening and closing state and target power.
Step S205, obtaining a plurality of operating parameters corresponding to the basic parameters according to the corresponding relationship.
And step S206, controlling the operation of the ventilation motor according to the internal and external circulation mode.
For example, when the current value of the basic parameter Y is 60, which is calculated according to the first formula, it can be seen from table 1 that the corresponding inner and outer circulation modes are 0x 2: the internal circulation and the external circulation respectively account for 50%, and the vehicle controller controls the ventilation motor to simultaneously carry out the internal circulation and the external circulation, and the internal circulation and the external circulation respectively account for 50%.
Both can adjust the temperature in the car room through the inner loop like this, can also carry out the circulation of air to the car room is inside and outside through the extrinsic cycle, prevent that the door window from hazing.
And step S207, controlling the operation of the blower according to the blowing mode and the gear of the blower.
For example, when the value of the basic parameter Y is 60, the corresponding blowing pattern is 0x0 according to table 2: in the blowing mode, the corresponding gear of the blower is 0x4:4, and the vehicle controller controls the blower to operate in the 4-gear blowing mode.
The gear of the blower is used for reflecting the wind speed of blowing, and the blowing mode can be used for reflecting the wind direction.
Step S208, judging whether the basic parameter is larger than a first threshold value. If so, step S209 is executed, otherwise, step S210 is executed.
In step S209, it is determined whether the basic parameter is greater than the second threshold. If yes, go to step S211.
And step S210, acquiring the target rotating speed of the compressor and starting the compressor.
Step S211, the compressor is turned off.
For example, in one implementation of the embodiments of the present application, referring to table 4, the first threshold may be 125 and the second threshold may be 135. When the Y value is less than or equal to 125, the compressor is started to output cold air, and when the Y value is more than 135, the compressor is closed.
In step S212, it is determined whether the basic parameter is greater than the third threshold, and if so, step S213 is executed.
In step S213, the target power of the vehicle heater is acquired, and the vehicle heater is started.
For example, in one implementation of an embodiment of the present application, referring to table 6, the third threshold may be 150. And after the compressor is closed, continuously judging whether the current basic parameter Y value is greater than a third threshold value, and when the Y value is greater than the third threshold value, indicating that hot air needs to be output at the moment. And then acquiring the target power of the vehicle-mounted heater corresponding to the Y value, and starting the vehicle-mounted heater to output hot air.
For example, when the value of the basic parameter Y is 60, it can be seen from table 4 that the compressor is started, and from table 5 and fig. 4 that the target rotation speed of the compressor is 3000rpm, the vehicle controller controls the compressor to operate at 3000 rpm.
As can be seen from tables 4 and 6, when the value of the basic parameter Y is located between 135-140, the compressor and the vehicle-mounted heater are both in the off state, that is, the temperature in the vehicle room is very close to the ambient temperature, the ventilation motor and the blower are still in the on state, the internal circulation and the external circulation can be performed simultaneously, and the external circulation has a higher specific gravity, which is equivalent to performing more circulation and replacement on the air in the vehicle room, so that the air in the vehicle room is fresher, or the air conditioning system can be manually turned off by a user.
In an implementation manner of the embodiment of the application, the heating of the whole vehicle is composed of two sub-vehicle heaters which have equal power and are both P0, so that the maximum power of the heating of the whole vehicle is 2P 0.
Specifically, referring to fig. 3, controlling the operation of the vehicle-mounted heater according to the open/close state of the vehicle-mounted heater and the target rotation speed may include:
step S301, determining whether the target power of the vehicle-mounted heater is greater than a first rotation speed threshold, if so, executing step S302, otherwise, executing step S307.
Wherein the first rotational speed threshold may be P0.
In step S302, flg1 is set to 1, T1 is set to Px/P0T, flg2 is set to 0, and T2 is set to 0.
Wherein, flg1 ═ 1 represents the on state, and flg2 ═ 0 represents the off state. T is one duty cycle of the vehicle heater, and T1 and T2 represent the on time. Px is the current target power of the vehicle heater, P0 is the maximum power of the vehicle heater, and Px/P0 × T represents the time required for operating at the current target rotational speed.
In step S303, ptc1 is flg1, ptc1_ t is t1, ptc2 is flg2, and ptc2_ t is t 2.
ptc1 denotes a first sub vehicle-mounted heater, ptc2 denotes a second sub vehicle-mounted heater, ptc1_ t denotes an operation time of the first sub vehicle-mounted heater, and ptc2_ t denotes an operation time of the second sub vehicle-mounted heater.
The first sub vehicle-mounted heater and the second sub vehicle-mounted heater respectively receive a first working state, a first working time, a second working state and a second working time. That is, the first sub-on-board heater is turned on, and the operation is performed for a time period of t1, and the second sub-on-board heater is turned off. At this time, the target power of the vehicle-mounted heater 3 is smaller than the maximum power of one sub vehicle-mounted heater, so that only one sub vehicle-mounted heater needs to be operated.
Step S304, judging whether the timing VCU _ t of the current vehicle controller is not less than the work period of one sub vehicle heater. If so, go to step S305, otherwise go to step S303.
When the first sub vehicle-mounted heater and the second sub vehicle-mounted heater receive the corresponding working state and working time, the vehicle controller starts timing, and the timing is the working time of the first sub vehicle-mounted heater.
And if the working time of the first sub vehicle-mounted heater does not reach a period, the first sub vehicle-mounted heater continues to work, and the second sub vehicle-mounted heater continues to be closed. 6
In step S305, ptc1 is flg2, ptc1_ t is t2, ptc2 is flg1, and ptc2_ t is t 1.
When the first sub vehicle-mounted heater operates for one period, the first sub vehicle-mounted heater and the second sub vehicle-mounted heater receive the working state and the working time again, at the moment, the first sub vehicle-mounted heater is turned off, the second sub vehicle-mounted heater is turned on, and the operation is carried out for a time period of t 1.
Step S306, judging whether the timing VCU _ t of the current vehicle controller is not less than the work period of one sub vehicle heater. If yes, go to step S303, otherwise go to step S305.
When the first sub vehicle-mounted heater and the second sub vehicle-mounted heater receive the working state and the working time again, the vehicle controller restarts timing, and the timing is the working time of the second sub vehicle-mounted heater.
When the second sub-vehicle-mounted heater operates for a period, the steps S303-S306 are repeated, namely the first sub-vehicle-mounted heater and the second sub-vehicle-mounted heater alternately switch to operate, so that the working states of the two sub-vehicle-mounted heaters are exchanged periodically, the working time of the two sub-vehicle-mounted heaters is basically kept consistent, the phenomenon that the sub-heaters are overused due to the fact that one sub-vehicle-mounted heater operates for a long time is avoided, and the whole service life can be further guaranteed.
In step S307, it is determined whether the target power of the vehicle-mounted heater is greater than the second rotational speed threshold, and if so, step S308 is executed.
The second rotational speed threshold may be 2P0, which is the maximum power at which the two onboard heaters operate simultaneously.
In step S308, flg1 is set to 1, T1 is set to T, flg2 is set to 1, and T2 is set to (Px-P0)/P0 is set to T.
Where, flg1 ═ 1 indicates an on state, and flg2 ═ 1 also indicates an on state. T is one duty cycle of the vehicle heater, and T1 and T2 represent the on time. Px is the current target power, P0 is the maximum power of one vehicle-mounted heater, (Px-P0)/P0 × T indicates the time required for one sub vehicle-mounted heater to operate at the target power, in addition to the full power operation for one cycle of the other sub vehicle-mounted heater.
In step S309, ptc1 is flg1, ptc1_ t is t1, ptc2 is flg2, and ptc2_ t is t 2.
ptc1 denotes a first sub vehicle-mounted heater, ptc2 denotes a second sub vehicle-mounted heater, ptc1_ t denotes an operation time of the first sub vehicle-mounted heater, and ptc2_ t denotes an operation time of the second sub vehicle-mounted heater.
The first sub-on-vehicle heater and the second sub-on-vehicle heater respectively receive a first working state, a first working time, a second working state and a second working time. That is, the first sub vehicle-mounted heater is turned on and operated for a period T, and the second sub vehicle-mounted heater is turned on and operated for a period T1. At the moment, the target power of the vehicle-mounted heater required by the whole vehicle heating is larger than the maximum power of one sub vehicle-mounted heater and smaller than the maximum power of two sub vehicle-mounted heaters, so that the two sub vehicle-mounted heaters need to be operated simultaneously, but the operation time of the two sub vehicle-mounted heaters is different.
The first sub vehicle-mounted heater needs to operate for a period, the second sub vehicle-mounted heater only needs to operate for a preset time period t2, and the preset time period t2 is smaller than the period, so that the second sub vehicle-mounted heater can operate simultaneously with the first sub vehicle-mounted heater, is turned off when the preset time period t2 is reached, or is in a turned-off state at first, and is turned on when the t2 time period is remained.
Step S310, judging whether the timing VCU _ t of the current vehicle controller is not less than the work period of one sub vehicle heater. If so, go to step S311, otherwise go to step S309.
When the first sub vehicle-mounted heater and the second sub vehicle-mounted heater receive the corresponding working state and working time, the vehicle controller starts timing, and the timing is the working time of the first sub vehicle-mounted heater.
And if the working time of the first sub vehicle-mounted heater does not reach a period, the first sub vehicle-mounted heater and the second sub vehicle-mounted heater continue to work.
In step S311, ptc1 is flg2, ptc1_ t is t2, ptc2 is flg1, and ptc2_ t is t 1.
When the first sub vehicle-mounted heater operates for one cycle, the first sub vehicle-mounted heater and the second sub vehicle-mounted heater receive the working state and the working time again, at the moment, the first sub vehicle-mounted heater operates only for a preset time period t2, and the second sub vehicle-mounted heater is started to operate for one cycle.
In step S312, it is determined whether the current time VCU _ t of the vehicle controller is not less than the duty cycle of one sub vehicle heater. If so, go to step S309, otherwise go to step S311.
When the first sub vehicle-mounted heater and the second sub vehicle-mounted heater receive the working state and the working time again, the vehicle controller restarts timing, and the timing is the working time of the second sub vehicle-mounted heater.
When the second sub-vehicle-mounted heater operates for a period, the steps S303-S306 are repeated, namely the working state and the working time of the first sub-vehicle-mounted heater and the second sub-vehicle-mounted heater are switched repeatedly, so that the operation time lengths of the two sub-vehicle-mounted heaters can be controlled to be basically consistent, and the phenomenon that the two sub-vehicle-mounted heaters are not used as a whole due to different use degrees is avoided.
In one implementation of the embodiment of the present application, the air conditioning operation control method may further include an "ECO" energy saving mode, and when the vehicle enters the energy saving mode, the vehicle controller may actively limit the target rotation speed of the compressor and the target power of the vehicle heater, for example, by multiplying the coefficients K1 and K2 to reduce the output rotation speed and power of the air conditioning system, thereby reducing the energy consumption of the vehicle.
And when the vehicle runs in the energy-saving mode, the running of the front defrosting mode or/and the rear defrosting mode of the blowing mode is not limited, so that the defrosting and demisting of the vehicle window can be completed as soon as possible, and the driving safety is ensured.
