Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
To make the objects, technical solutions and advantages of the present application more clear, the following description is made by way of specific embodiments with reference to the accompanying drawings.
At present, a vehicle fan is controlled by a vehicle controller of a vehicle, and due to different vehicle manufacturers, the control logic of the vehicle fan by the vehicle controller is greatly different. For example, the air conditioning controller may generate and send a fan control request to the vehicle control unit, which controls the vehicle fan based on the fan control request. For another example, the vehicle controller may determine and monitor the air conditioner pipeline pressure, and when the air conditioner pipeline pressure reaches a preset threshold (which is generally considered by industry personnel that the compressor is started under the condition), the vehicle controller automatically generates a fan control request based on a preset control logic, and then controls the vehicle fan based on the fan control request.
However, the applicant found that, in a control method in which an air conditioner controller generates a fan control request or a control method in which a vehicle control unit generates a fan control request, an abnormal fan control request may occur and the control method may be concentrated on a situation in which an air conditioner compressor cannot be started. For example, when the entire vehicle is not in a high-voltage state, the compressor cannot be started because the voltage does not reach the starting voltage, but the air conditioner controller still generates a fan control request, that is, an abnormal fan control request occurs for unknown reasons.
The conventional automobile fan control method has a problem of poor control effect because the abnormal fan control request causes the fan to idle, which causes unnecessary energy consumption and NVH (noise vibration harshness).
In order to solve the prior art problems, embodiments of the present application provide a method and an apparatus for controlling a vehicle fan, a storage medium, an electronic device, and a vehicle. The following first describes a control method of a vehicle fan provided in an embodiment of the present application.
The main body of the vehicle fan control method may be a vehicle fan control device, and the vehicle fan control device may be an electronic device having a processor and a memory, such as a vehicle control unit, an air conditioner controller, and the like, which is not specifically limited herein.
Based on the foregoing, it is considered that the abnormal fan control request is generally concentrated on the situation where the air conditioner compressor cannot be started, and therefore, the fan control request generated in the case where the compressor is not started may be regarded as the abnormal fan control request, and accordingly, the fan control request generated in the case where the compressor has been started may be regarded as the normal fan control request.
Because it is difficult to determine whether the compressor is started, for example, in the case of an abnormal air conditioner controller, it is difficult to ensure the accuracy of the generated compressor start signal, therefore, it is possible to determine whether the fan control request is abnormal by the condition that the compressor needs to be normally started, for example, the vehicle is in a high-pressure state, and then determine whether to respond to the fan control request according to the abnormal condition of the fan control request, so as to control the fan to operate.
Referring to fig. 1, it shows a flowchart of an implementation of a control method of a vehicle fan provided in an embodiment of the present application, which is detailed as follows:
and step 110, acquiring a whole vehicle state signal of the target vehicle when the fan control request of the target vehicle is detected.
In some embodiments, the target vehicle may be any hybrid or electric vehicle. The vehicle status signal may be a related status signal related to compressor starting, for example, the vehicle status signal may be one or more of a driving status flag, a charging status flag, a battery thermal management status flag, and a keyless entry and start status flag.
Specifically, the control device of the vehicle fan may detect a fan control request of the target vehicle. For example, the control device of the vehicle fan may compare the received data of the air conditioner controller to detect whether it issues a fan control request. When the control device of the vehicle fan detects a fan control request, a vehicle state signal of the target vehicle may be acquired. For example, the control device of the vehicle fan may obtain a corresponding vehicle signal from a corresponding control device of the target vehicle, such as a charge status indicator from the charge controller.
And step 120, judging whether the vehicle state signal meets a preset fan starting condition.
In some embodiments, the preset fan start condition may be a condition that needs to be satisfied for a normal start of the compressor. For example, the preset fan start condition may be any one of a driving state flag as an on flag, a charging state flag as an on flag, a battery thermal management state flag as an on flag, and a keyless entry and start state flag as an on flag. It should be noted that any one of the conditions exemplified above can ensure the normal start of the compressor.
Specifically, after the control device of the vehicle fan obtains the vehicle state signals, whether the vehicle state signals meet the preset fan starting conditions or not can be judged.
A specific implementation of step 120 is given below, and the corresponding processing may be as follows:
if all the state marks in the finished automobile state signal are non-opening marks, the finished automobile state signal can be judged not to meet the preset fan starting condition. If the whole vehicle state signal comprises the driving state identification and the driving state identification is the opening identification, the whole vehicle state signal can be judged to meet the preset fan starting condition. If the vehicle state signal comprises the charging state identification and the charging state identification is the opening identification, the vehicle state signal can be judged to meet the preset fan starting condition. If the vehicle state signal comprises a battery thermal management state identifier and the battery thermal management state identifier is a starting identifier, the vehicle state signal can be judged to meet the preset fan starting condition. If the whole vehicle state signal comprises the keyless entry and starting state identifier, and the keyless entry and starting state identifier is an opening identifier, the whole vehicle state signal can be judged to meet the preset fan starting condition.
And step 130, responding to the fan control request if the vehicle state signal meets the preset fan starting condition, and otherwise rejecting the fan control request.
When the control device of the vehicle fan judges that the vehicle state signal meets the preset fan starting condition, the control device can respond to the fan control request to control the fan to operate. When the control device of the vehicle fan judges that the vehicle state signal does not meet the preset fan starting condition, the fan control request can be refused.
In this way, the control device of the vehicle fan does not directly respond to the fan control request after receiving the fan control request, but determines whether the fan control request is abnormal. When the fan control request is judged to be a normal fan control request, the fan control request is responded, so that the problems of energy consumption and NVH (noise, vibration and harshness) caused by the phenomenon that the fan idles due to the fact that the compressor is not started are solved, and the control effect of the fan is improved.
In some embodiments, for the case that the fan control request carries the fan duty ratio information, the specific process of responding to the fan control request in step 130 may be as follows: the fan of the control target vehicle operates according to the fan duty ratio information.
In some embodiments, the fan control request carrying the fan duty cycle information is generally generated by an air conditioner controller, and for such a fan control request, the control device of the vehicle fan may directly extract the fan duty cycle information carried therein and then send the fan duty cycle information to the fan to control the fan to operate according to the fan duty cycle information.
In other embodiments, for the case that the fan control request does not carry the fan duty ratio information, the specific processing of responding to the fan control request in step 130 may be as follows: acquiring a current speed value and a current pipeline pressure value of a target vehicle; determining target fan duty ratio information corresponding to the current speed value and the current pipeline pressure value together according to the preset corresponding relation among the speed, the pressure and the fan duty ratio; and controlling the fan of the target vehicle to operate according to the target fan duty ratio information.
In some embodiments, the preset correspondence between the vehicle speed and the fan duty ratio may be a correspondence, such as a table-type correspondence, recorded with the fan duty ratios corresponding to different vehicle speeds and different pressures. As shown in Table one, a method is provided in which various kinds of correspondence are changed.
Watch 1
Therefore, when the control device of the vehicle fan judges that the whole vehicle state signal meets the preset fan starting condition, the current vehicle speed value and the current pipeline pressure value of the target vehicle can be obtained, and then the target fan duty ratio information corresponding to the current vehicle speed value and the current pipeline pressure value together can be obtained through table lookup, so that the fan can be controlled to operate according to the target fan duty ratio information.
The applicant has also found that in the current fan control process in which a fan control request is generated by an air conditioner controller, the fan is usually delayed from the compressor start-up because the air conditioner controller firstly sends a start-up command to the compressor and then sends a fan control request to the vehicle controller after the compressor start-up is completed. Because the fan does not rotate in the starting process of the compressor, the heat of the compressor is difficult to radiate, the pressure of an air-conditioning pipeline in a short time is larger, and the refrigerating performance of the compressor is reduced.
In view of the above problems, the present application adjusts the sending logic of the fan control request of the air conditioner controller, that is, the fan control request is sent by the air conditioner controller of the target vehicle synchronously when sending the start instruction to the compressor of the target vehicle. So, can realize fan operation and compressor start-up in step, like this, the compressor heat can be blown away to the fan in compressor start-up process, avoids appearing the great phenomenon of air conditioner pipeline pressure, has guaranteed the stability of air conditioner pipeline pressure, and then has promoted the refrigeration performance of compressor.
In the embodiment of the application, after the fan control request is received, the fan control request is not directly responded, and whether the fan control request is abnormal or not is judged. When the fan control request is judged to be a normal fan control request, the fan control request is responded, so that the problems of energy consumption and NVH (noise, vibration and harshness) caused by the phenomenon of fan idling due to the fact that the compressor is not started are solved, and the control effect of the fan is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
In the following, embodiments of the apparatus of the present application are provided, and for details which are not described in detail therein, reference may be made to the corresponding method embodiments described above.
