The present application claims priority to Chinese Patent Application No. 202311332060.9 filed in the Chinese National Intellectual Property Administration on Oct. 13, 2023, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to a control technology field of a vehicle, and particularly, to a system and a method of controlling an intake rate of a vehicle blower.
With supply of electric vehicles, electric vehicles without an automatic defogging sensor (ADS) are popular due to low prime cost compared to electric vehicles with the ADS. However, in the case of the electric vehicles without the ADS, power consumption of a positive temperature coefficient (PTC) element is increased due to heating of the PTC element in a low temperature environment, and all electric range (AER) of the electric vehicle is decreased. Furthermore, in the case of the electric vehicle without the ADS, when a vehicle velocity is high and a blower step number is low, a suction pressure of the blower is low, so external cold air is introduced into the vehicle, and this may lower a temperature of a foot region and a temperature of a head region of a driver on a front seat. Furthermore, because the electric vehicle without the ADS cannot sense external temperature and humidity information of the vehicle, an intake rate of the blower cannot be controlled according to a change of an external environment, so fogging is easily generated on a front window.
Therefore, in the case of the electric vehicle without the ADS, a system and a method that can intelligently control the intake rate of the vehicle blower is desperately needed.
The information included in this Background of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Various aspects of the present disclosure are directed to determining whether control of an intake rate of a blower is turned on by obtaining passenger seating information of a passenger seat, vehicle velocity information, and a blower step number of an electric vehicle without an ADS to reduce power consumption of a positive temperature coefficient (PTC) element, increase a winter-season all electric range (AER) of the electric vehicle, and driving and boarding comfort of a driver and a passenger.

The methods and apparatuses of the present disclosure have other features and advantages which will be apparent from or are set forth in more detail in the accompanying drawings, which are incorporated herein, and the following Detailed Description, which together serve to explain certain principles of the present disclosure.
It may be understood that the appended drawings are not necessarily to scale, presenting a somewhat simplified representation of various features illustrative of the basic principles of the present disclosure. The specific design features of the present disclosure as included herein, including, for example, specific dimensions, orientations, locations, and shapes will be determined in part by the particularly intended application and use environment.
In the figures, reference numbers refer to the same or equivalent portions of the present disclosure throughout the several figures of the drawing.
Reference will now be made in detail to various embodiments of the present disclosure(s), examples of which are illustrated in the accompanying drawings and described below. While the present disclosure(s) will be described in conjunction with exemplary embodiments of the present disclosure, it will be understood that the present description is not intended to limit the present disclosure(s) to those exemplary embodiments of the present disclosure. On the other hand, the present disclosure(s) is/are intended to cover not only the exemplary embodiments of the present disclosure, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the present disclosure as defined by the appended claims.
Hereinafter, an exemplary embodiment of the present disclosure will be described in detail, and the exemplary embodiment of the present disclosure will be conducted on the premise of the technical measure of the present disclosure, and a detailed implementation method and a specific operation process are presented, but the protection scope of the present disclosure is limited to the following exemplary embodiment of the present disclosure.
Hereinafter, an exemplary embodiment of the present disclosure will be described in detail with reference to drawings.
When a vehicle velocity is high and a blower step number is low in a low-temperature environment, a suction pressure of the blower is low, so external cold air flows into a driving room (marked by a dotted arrow “X” in
The blower step number detection device 200 may be configured to detect the step number of the blower. The blower may have a plurality of step numbers such as first step to eighth step. The higher the step number of the blower is, the larger a blowing amount is. For example, the step number of the blower may indicate the blowing amount of the blower. The vehicle velocity detection device 300 may be configured to detect a current vehicle velocity of the vehicle. The passenger seat seating detection device 400 may be configured to detect whether the passenger is seated on the passenger seat. The passenger seat seating detection device 400 is not limited to, but may include a seat pressure sensor, a safety belt sensor, etc. configured for sensing whether the passenger is seated on the passenger seat. The HVAC control device 100 may be electrically connected to each of the blower step number detection device 200, the vehicle velocity detection device 300, and the passenger seat seating detection device 400, and may be configured to receive information from the blower step number detection device 200, the vehicle velocity detection device 300, and the passenger seat seating detection device 400, and determine whether the control of the intake rate of the blower is turned on according to the detected current step number of the blower, the current vehicle velocity, and the passenger seat seating information when the blower is turned on as the vehicle is started.
Hereinafter, an operation of the system of controlling an intake rate of a vehicle blower according to an exemplary embodiment of the present disclosure will be described in detail.
In step S21, it is detected whether the electric vehicle is started, and in step S22, it is detected whether the blower is turned on. When the electric vehicle is started and the blower is turned on, it is detected whether the current blower step number is a predetermined step number in step S23. When the detected current blower step number is not the predetermined step number (i.e., when the detected current blower step number is a step number other than the predetermined step number among the plurality of step numbers), the HVAC control device may turn on an intake rate control function of the blower, and when the detected current blower step number is the predetermined step number, the HVAC control device may turn off the intake rate control function of the blower. The predetermined step number may be set to the first step, but the present disclosure is not limited thereto.
When the electric vehicle is not started or the blower is not turned on, the HVAC control device 100 turns off the intake rate control function of the blower.
According to an exemplary embodiment of the present disclosure, turning on the intake rate control function means further determining whether the control of the intake rate of the blower is turned on based on the detected current blower step number, the current vehicle velocity, and the passenger seat seating information. Turning off the intake rate control function means maintaining the existing intake rate control without conducting subsequent determination.
Hereinafter, a specific process of the turning on the intake rate control function in the method of controlling an intake rate of a vehicle blower according to an exemplary embodiment of the present disclosure will be described in detail.
According to an exemplary embodiment of the present disclosure, in a situation in which the intake rate control function is determined to be turned on, the HVAC control device 100 is configured to determine whether a current intake rate control state is in an intake rate control ON area or in an intake rate control OFF area based on an intake rate control mapping table according to the detected current vehicle velocity information and the current blower step number. The HVAC control device 100 is configured to determine whether the current intake rate control state is changed between the intake rate control ON area and the intake rate control OFF area, and then is additionally configured to determine whether the intake rate control of the blower is turned on based on whether the passenger is seated on the passenger seat and the change of the current intake rate control state between the intake rate control ON area and the intake rate control OFF area.
The HVAC control device 100 may include a processor and a memory, and the memory stores a predetermined intake rate control mapping table (shown in Table 1 below) based on the vehicle velocity information and the blower step number. The intake rate control mapping table is divided into the intake rate control ON area and the intake rate control OFF area. As shown in Table 1 below, symbol ‘⊚” represents the intake rate control ON area and symbol “X” represents the intake rate control OFF area.
When the blower step number is 1st step, the suction pressure of the blower is low and the external cold air easily flows into the driving room to lower the temperature at the side foot region of the passenger and the temperature at the side head region of the driver, referring back to
According to an exemplary embodiment of the present disclosure, the turning on the intake rate control is to make the internal circulation intake ratio of the blower reach a predetermined ratio. The predetermined ratio may be set to 10%, 20%, 30%, 40%, 50%, etc. of the total intake amount. Furthermore, when reducing a cause such as a fogging risk of a vehicle window is considered, the predetermined ratio may be 30%. However, the present disclosure is not limited to such the predetermined ratios.
Accordingly, when the current vehicle velocity information and the current blower step number are detected, the HVAC control device 100 may be configured to determine whether the current intake rate control state is in the intake rate control ON area or the intake rate control OFF area based on the intake rate control mapping table, and determine the change of the current intake rate control state, i.e., whether the current intake rate control state is changed from the intake rate control ON area to the intake rate control OFF area or whether the current intake rate control state is changed from the intake rate control OFF area to the intake rate control ON area.
Referring to
When it is determined that the passenger is seated on the passenger seat (“Yes” in the step S31), the HVAC control device 100 determines whether the current intake rate control state is changed in step S32, that is, determines the current intake rate control state in real time based on the intake rate control mapping table and determines whether the current intake rate control state is changed, according to the current vehicle velocity information and the current blower step number.
When it is determined that the current intake rate control state is changed from the intake rate control ON area to the intake rate control OFF area in step S33, or it is determined that the current intake rate control state is changed from the intake rate control OFF area to the intake rate control ON area in step S34, the HVAC control device 100 is configured to determine whether a time for which the current intake rate control state is maintained is equal to or greater than a first intake rate control switching delay time in S35.
In a state of concluding that the current intake rate control state is changed from the intake rate control ON area to the intake rate control OFF area, when the time for which the current intake rate control state is maintained at the intake rate control OFF area is equal to or greater than the first intake rate control switching delay time (i.e., “Yes” in step S35), the intake rate control is maintained to be OFF to prevent the temperature of the foot region of the passenger from being lowered. When the time for which the current intake rate control state is maintained at the intake rate control OFF area is less than the first intake rate control switching delay time (i.e., “No” in the step S35), the intake rate control is maintained to be ON. That is, when the current intake rate control state is not maintained for the first intake rate control switching delay time, but is changed, the intake rate control is not switched, but the state change and the maintenance time are determined again.
Similarly, in a state of concluding that the current intake rate control state is changed from the intake rate control OFF area to the intake rate control ON area, when the time for which the current intake rate control state is maintained at the intake rate control ON area is equal to or greater than the first intake rate control switching delay time (i.e., “Yes” in step S36), the intake rate control is made to be changed to ON to reduce the power consumption of the PTC. When the time for which the current intake rate control state is maintained at the intake rate control OFF area is less than the first intake rate control switching delay time (i.e., “No” in the step S36), the intake rate control is maintained to be OFF. That is, the switching is not conducted.
When it is determined that the passenger is not seated on the passenger seat (“No” in the step S31), it is determined whether the current intake rate control state is changed in step S37. When it is determined that the current intake rate control state is changed from the intake rate control ON area to the intake rate control OFF area in step S38, it is determined whether the time for which the current intake rate control state is maintained is equal to or greater than a second intake rate control switching delay time. When it is determined that the current intake rate control state is changed from the intake rate control OFF area to the intake rate control ON area in step S39, it is determined whether the time for which the current intake rate control state is maintained is equal to or greater than the first intake rate control switching delay time.
In a state of determining whether the current intake rate control state is changed from the intake rate control ON area to the intake rate control OFF area, when the time for which the current intake rate control state is maintained at the intake rate control OFF area is equal to or greater than the second intake rate control switching delay time (i.e., “Yes” in step S40), the intake rate control is changed to be OFF to prevent the temperature of the head region of the driver from being lowered. When the time for which the current intake rate control state is maintained at the intake rate control OFF area is less than the second intake rate control switching delay time (i.e., “No” in the step S40), the intake rate control is maintained to be ON, and the switching is not conducted.
Similarly, in the state of determining that the current intake rate control state is changed from the intake rate control OFF area to the intake rate control ON area, when the time for which the current intake rate control state is maintained at the intake rate control ON area is equal to or greater than the first intake rate control switching delay time (i.e., “Yes” in step S41), the intake rate control is made to be changed to ON to reduce the power consumption of the PTC. When the time for which the current intake rate control state is maintained at the intake rate control ON area is less than the first intake rate control switching delay time (i.e., “No” in the step S41), the intake rate control is maintained to be OFF. That is, the switching is not conducted.
According to an exemplary embodiment of the present disclosure, the first intake rate control switching delay time and the second intake rate control switching delay time may be predetermined and stored in the memory of the HVAC control device 100. When the passenger is seated on the passenger seat, the intake rate control OFF area may be maintained for 10 seconds, and then the temperature of the foot region of the passenger at the passenger seat may be significantly lowered. When the passenger is not seated on the passenger seat, the intake rate control OFF area may be maintained for 70 seconds, and then the temperature of the side head region of the driver may be significantly lowered. In one example, the first intake rate control switching delay time may be set to 10 seconds, and the second intake rate control switching delay time may be set to 70 seconds, but the present disclosure is not limited thereto.
According to an exemplary embodiment of the present disclosure, it is determined whether the intake rate control of the blower is turned on by obtaining the passenger seating information of the passenger seat, the vehicle velocity information, and the blower step number of the electric vehicle without an ADS to prevent the temperature of the foot region of the passenger at the front seat and the temperature of the head region of the driver from being lowered in a low-temperature environment, to enhance driving and boarding comfort of the driver and the passenger, and to increase a winter-season all electric range (AER) of the electric vehicle by reducing the power consumption of the positive temperature coefficient (PTC) element.
