Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.

Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

Referring to fig. 1 and 2, there are shown, in hardware and software respectively, system block diagrams of one embodiment of a method according to the invention for automatically controlling the blower 3 of a vehicle after the vehicle has switched off (corresponding to a power outage in an electric vehicle). Wherein IGN is Ignition, namely Ignition; b + is the positive electrode of the battery pack; GND is grounded; DC Input is direct current Input; PWM Input is pulse width modulation Input; v _ Diag = f (lmot) is a feedback signal output based on fan motor current; the LPM is a Linear Power Module, namely a Linear Power Module; m is HVAC Fan Motor, namely air conditioner blower Motor; OAT (outside Air temperature) is the external temperature; SOC (State Of Charge) is the state Of charge; PWM is pulse width modulation.

The vehicle has a body control module 1, wherein the method comprises the following steps:

the vehicle body control module 1 judges: when the vehicle is in a flameout state, the external temperature value (i.e. the external air temperature) is higher than the external temperature value calibration value (i.e. the scale that the user has an incentive to start the compressor for cooling, and the usable range is 10-20 degrees, wherein the reason for considering the external temperature is mainly that the user generally does not start the compressor for cooling under the condition that the external temperature is too low, and therefore the fan does not need to be started for drying the condensed water), and the compressor start time is longer than the compressor calibration value (i.e. the time scale of the occurrence of the condensed water, and the range is 4 minutes to 8 minutes), the vehicle body control module 1 outputs a signal, generally a pulse width modulation signal (because the current fan circuit interfaces are all pulse width modulated, and therefore the corresponding output pulse width modulation signal is generally required for driving the blower 3 to. It should be understood that the Body Control Module (BCM) coordinates different functions in the vehicle by signals, and implements discrete Control functions to Control a plurality of electrical appliances, for example, including electric door and window Control, central door lock Control, remote anti-theft Control, lighting system Control, electric rearview mirror heating Control, instrument backlight adjustment, power distribution, etc. Furthermore, the compressor on time is taken into account in order to determine whether the air conditioning evaporator is running for a time sufficient to enable the formation of condensate to be dried, otherwise there is no need to automatically activate the blower 3 to dry the condensate in the event of a switch-off. Thereby, the automatic starting function of the blower 3 after being turned off is integrated into the vehicle body control module 1.

In the illustrated embodiment, the vehicle body control module 1 further determines: when the state of charge of the battery pack of the vehicle is greater than a state of charge calibration value (available value range thereof is 55% to 65%), when the battery pack voltage of the vehicle is between a voltage upper limit value (available value range thereof is 16.5V to 18.5V) and a voltage lower limit value (available value range thereof is 6.5V to 8.5V), the vehicle is not in a remote start state, and/or the vehicle is not in a logistics mode, the body control module 1 outputs the pulse width modulation signal for driving the blower 3 to be turned on. It will be appreciated that the state of charge or the voltage of the battery pack is taken into account in order to prevent the battery pack from being insufficiently supported to perform other functions, typically more important than a smell, due to a possible shortage of power. The remote start-up and logistics mode are considered because the remote start-up and logistics mode are two special modes. In the remote starting state, the vehicle state is under the appeal of user remote control, and the vehicle should completely respond to the user requirement, so corresponding control is not performed. In the logistics mode, it is required to ensure that the electric quantity of the whole vehicle is consumed as little as possible before the vehicle is transported to the destination, so that the function is limited to meet the requirement of reducing energy consumption.

Furthermore, as can also be seen from the figure, a function enabling flag is set at the vehicle body control module 1, the function enabling flag has an on state and an off state, and the vehicle body control module 1 further determines that: when the function enabling flag bit is in the on state, the vehicle body control module 1 outputs the pulse width modulation signal to drive the blower 3 to be turned on. It will be appreciated that the state of the function enabling flag can be determined by the user, whereby the method of the invention can be performed not only automatically, but also by the user, with intervention according to his experience or will. For example, the user may set the function enable flag to the off state, considering that the power consumption of the battery of the entire vehicle increases due to turning on the blower 3 after turning off the engine.

The vehicle body control module 1 controls the blower 3 together with the manual air conditioning controller 2 of the vehicle. That is, the method of the present invention does not affect the control of the blower 3 by the manual air conditioner controller 2. For example, when the IGN state is ON, the manual air conditioner controller 2 is only allowed to control the blower 3, and thus the present method does not conflict with the manual air conditioner controller 2. When the IGN state is OFF, the blower 3 can be controlled by both the method according to the invention and the manual air conditioning controller 2.

In addition, after triggering the automatic turning on of the blower 3, the BCM controls the blower 3 to blow air, and turns off the blower 3 after keeping blowing air for a certain time. It should be appreciated that the user is able to adjust the certain time according to the actual situation, such as his experience and information about the surrounding environment, vehicle type, etc. Of course, in addition to setting the certain time, a condition for triggering automatic turning off of the blower 3 may be set similarly to the condition for triggering automatic turning on of the blower 3. For example, the vehicle body control module 1 further determines: when the external temperature value is less than or equal to the external temperature value calibration value, the vehicle body control module 1 outputs another signal, for example, a pulse width modulation signal, for driving the blower 3 to close. Of course, in addition to the condition that the external temperature value is equal to or less than the external temperature value calibration value, the condition that the blower 3 is turned off can include that the vehicle is returned from an off state into an ignition (running) state, the state of charge of the battery pack of the vehicle is equal to or less than the state of charge calibration value, the battery pack voltage of the vehicle is in addition to the voltage upper limit value and the voltage lower limit value, the vehicle is in the remote start state, the vehicle is in the logistics mode, and/or the function enabling flag is in the off state, and the like. Specifically, the body control module 1 may not turn on the blower 3 until it is determined that the condition for turning on the blower 3 is satisfied, and if the battery level/voltage is lower than the lower limit (for example, the battery level is lower than 30% to 20% and the voltage is lower than 6V to 4V) after the blower is turned on, the body control module 1 may fail to operate, which may cause the function to be interrupted, and in addition, the vehicle may be in a remote start or a logistics mode, which may also interrupt the function. In addition, the external temperature condition can be optionally used only as an admission condition for opening the function in addition to being one of the shutdown conditions, so that the external temperature condition can not be exited due to a change in the external temperature.

It should be noted that the relationships of the logical conditions are not necessarily all satisfied, and may be determined in accordance with actual circumstances.

The invention also relates to an automatic control system for a blower 3 of a vehicle, comprising the body control module 1 and the blower 3, wherein the automatic control system is adapted to perform any of the methods described above. It should be understood that the body control module 1 and the blower 3 are in signal communication such that the body control module 1 controls the blower 3 with a signal, such as a pulse width modulated signal.

It should be understood that the automatic control system of the present invention may be installed in a variety of vehicles, including cars, vans, passenger cars, hybrid vehicles, electric vehicles, and the like. Therefore, the subject matter of the present invention is also intended to protect various vehicles equipped with the automatic control system of the present invention.

In summary, the contribution of the in-vehicle air conditioner peculiar smell improvement control method and system applicable to the manual air conditioning system of the invention lies in that: automatically starting an air conditioner blower to blow dry the evaporator condensate water after flameout so as to treat the peculiar smell generation source; and the blower control after flameout is realized through the vehicle body controller.

It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which would occur to persons skilled in the art upon consideration of the above teachings, are intended to be within the scope of the invention.
