Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
An embodiment of the present invention provides a vehicle parking control method, as shown in fig. 1, including:
s101, when a vehicle parking instruction is obtained, obtaining a set vehicle parking duration and detecting the actual environment temperature of the environment where the vehicle is located at the current moment;
s102, acquiring a predicted environment temperature within a parking time;
s103, determining the lowest temperature of the actual environment temperature and the predicted environment temperature;
s104, judging whether the lowest temperature is lower than a preset temperature or not, and obtaining a judgment result, wherein the preset temperature is a set freezing temperature;
and S105, performing shutdown control on the vehicle fuel system based on the judgment result.
First, in S101, when a vehicle parking instruction is acquired, a set vehicle parking time period is acquired, and an actual ambient temperature of an environment in which the vehicle is located at the present time is detected.
The application scenario of the present invention is that a user operates a vehicle to park, and at this time, a set vehicle parking duration is obtained, where the vehicle parking duration may be obtained through a display screen of a console in the vehicle, or may be received and sent by the user through an intelligent terminal, and is not limited herein.
For example, when the vehicle parking instruction is acquired, the vehicle parking duration is acquired based on the selection operation of the user. The user inputs the length of time for parking on the display screen of the console, which may be, for example, 3 days, 5 days, or half a month, etc. Of course, if the selection operation of the user is not received, the parking duration of the vehicle may be directly determined as a preset duration, and the preset duration may be 1 day or half a day, which is set according to the parking habit of the user, so as to facilitate the operation of the user, which is not limited herein.
Meanwhile, when the set parking time of the vehicle is obtained, the actual environment temperature of the environment where the vehicle is located at the current moment is also detected.
The actual ambient temperature may be acquired by a temperature sensor disposed around the vehicle, and is not limited herein.
Next, S102 is executed to acquire the predicted ambient temperature within the parking period.
Specifically, the weather forecast information in the future time, that is, the predicted ambient temperature, obtained by the MP5 car networking system on the vehicle may be used, or the console may be connected to an intelligent terminal, and the weather forecast information in the future time may be obtained from the intelligent terminal.
The predicted ambient temperature includes ambient temperatures at a plurality of times within the parking duration, and all are predicted values.
Next, S103 is executed to determine the lowest temperature of the actual ambient temperature and the predicted ambient temperature.
The minimum temperature may be the actual ambient temperature or may be a predicted ambient temperature at any time during the parking period. Therefore, the minimum temperature during the parking time needs to be estimated by determining the minimum temperature as described above.
Specifically, the predicted ambient temperatures are compared with each other and the predicted ambient temperature is compared with the actual ambient temperature, and the lowest temperature of the actual ambient temperature and the predicted ambient temperature is determined.
Next, S104 is executed to determine whether the lowest temperature is lower than a preset temperature, and obtain a determination result, where the preset temperature is the set freezing temperature.
And comparing the determined lowest temperature with the set icing temperature, and if the lowest temperature is lower than the preset temperature, determining that the vehicle fuel electric system will be iced in the parking time. And if the lowest temperature is not less than the preset temperature, determining that the vehicle fuel electric system can not be frozen in the parking time.
The preset temperature is a value exceeding a preset range of the freezing temperature of the water, namely the freezing temperature of the water is 0 ℃, and the preset temperature is greater than 0 ℃ so as to reserve a certain redundancy value to deal with the situation that the acquired temperature value has errors.
Finally, S105 is executed, and based on the determination result, the vehicle fuel system is subjected to stop control.
Specifically, when the judgment result is yes, the fact that the vehicle fuel-electric system can be frozen in the parking time is determined, the vehicle fuel-electric system is controlled to start purging, the vehicle is controlled to stop after purging, water in the vehicle fuel-electric system is blown to the air as soon as possible, and the vehicle cannot be frozen even if the temperature is lower than the freezing temperature of the water in the parking time.
And if the judgment result is negative, determining that the vehicle fuel electric system is not frozen in the parking time, and controlling the vehicle fuel electric system to normally park, wherein although water exists in the vehicle fuel electric system at the moment, the freezing phenomenon does not occur because the temperature lower than the freezing temperature of the water does not occur in the parking time. Furthermore, the inside of the stack is required to maintain a certain humidity during the electrochemical reaction of the vehicle fuel system. The purging of the vehicle fuel electric system is not performed every time when the vehicle is stopped, and on the other hand, the service life and the performance of the vehicle fuel electric system can be improved.
The specific execution flow of the present invention is shown in fig. 2, and includes:
s201, when a vehicle parking instruction is obtained, the vehicle parking time length is obtained.
S202, detecting the actual environment temperature of the environment where the vehicle is located at the current moment.
Then, S203, the predicted environmental temperature in the parking time is obtained,
next, S204, determining the lowest temperature of the predicted environment temperature and the actual environment temperature;
s205, judging whether the lowest temperature is lower than a preset temperature, wherein the preset temperature is a set freezing temperature;
if yes, S206 is executed, the vehicle fuel system is controlled to stop at low temperature, namely, the vehicle is stopped after the purging is started;
if not, S207 is executed, and the vehicle fuel system is controlled to be normally stopped, namely, directly stopped.
According to the technical scheme, the vehicle fuel electric system is controlled to be shut down at a low temperature only when the low temperature lower than the preset temperature appears in the actual environment temperature of the environment where the vehicle is located at the current moment and the predicted environment temperature within the parking time, and the vehicle fuel electric system is normally shut down at other times.
One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:
the invention provides a vehicle parking control method, which comprises the steps of obtaining set vehicle parking duration and detecting the actual environment temperature of the environment where a vehicle is located at the current moment when a vehicle parking instruction is obtained; obtaining a predicted environment temperature within the parking time, and determining the lowest temperature of the actual environment temperature and the predicted environment temperature; judging whether the lowest temperature is lower than a preset temperature or not, and obtaining a judgment result, wherein the preset temperature is a set freezing temperature; based on the judgment result, the vehicle fuel-electric system is shut down and controlled, and then when the vehicle fuel-electric system is frozen in the estimated parking time, water generated in the vehicle fuel-electric system is blown dry firstly, so that the freezing phenomenon is avoided, and the performance of the vehicle fuel-electric system is further prevented from being rapidly attenuated or damaged.
