Description
Technical Field
The invention belongs to the technical field of automobile control, and particularly relates to an automobile intelligent ventilation control method, system, equipment and storage medium.
Background
In hot summer, the vehicle is hot in burning sun, and if the vehicle is parked outdoors for a long time, the temperature in the vehicle can be rapidly increased, and experimental data show that when the temperature outside the vehicle reaches 29 ℃, after a vehicle door is closed, the temperature in the vehicle can reach more than 50 ℃ within half an hour. With the rise of the temperature in the automobile, harmful organic volatile matters such as benzene and aldehydes generated by automotive upholstery, leather and the like are also released and gathered in the closed high-temperature environment in the automobile, and if the automobile is used under the condition, the comfort level of a user is reduced, the experience feeling of the user is influenced, and meanwhile, the adverse influence on the body health of the user is possibly caused. The temperature in the vehicle is maintained not to be too high, so that the use and experience of a user after getting on the vehicle are not influenced, and the release and accumulation of harmful organic volatile matters caused by long-term sealing in the vehicle are reduced, so that the requirement is very necessary.
At present, the ventilation scheme by using the existing equipment of the vehicle mainly comprises two schemes, which are respectively as follows:
one is timing ventilation, after the vehicle is flamed out and sleeps, the air conditioner controller accumulates and times by effective time signals (such as effective Beijing time signals) received before the dormancy after the user passes through a ventilation time point defined by a central control screen or other terminals, when the ventilation time point defined by the user is timed, whether the current storage battery voltage is greater than a set voltage value is judged, if so, an active ventilation action is executed, otherwise, the active ventilation action is not executed. And during ventilation, the air conditioner controller controls the mode air door to the blowing surface foot blowing mode, controls the air blower to ventilate to a set time length according to the external circulation with fixed air quantity, then switches to the internal circulation ventilation to the set time length, and finally switches to the external circulation ventilation to the set time length.
The other method is to carry out ventilation according to the difference between the internal temperature and the external temperature, and mainly comprises the following steps:
1. the control unit acquires the current vehicle position, weather, air quality and the state of the power supply device to judge whether the parking position has a precondition for executing an automatic ventilation function;
2. if the precondition for executing the automatic ventilation function is met, the control unit detects the temperature inside the vehicle and the temperature outside the vehicle at regular time in the parking process; if not, ending the flow;
3. if the temperature inside the vehicle is higher than the temperature outside the vehicle by a set threshold value T1 and the power supply device meets the voltage or electric quantity requirement for executing ventilation, the ventilation execution unit is controlled to act, the fresh air door is controlled to be opened, and fresh air with low temperature and clean outside the vehicle is introduced to ventilate and purify the closed passenger compartment.
4. If the power supply device does not meet the voltage or electric quantity requirement for executing ventilation at the moment, the control unit sends request information for starting the engine or other power supply devices to the vehicle-mounted wireless communication unit, and the vehicle-mounted wireless communication unit pushes information for inquiring starting the engine or other power supply devices for ventilation to a user through the mobile information interaction terminal;
5. if the vehicle-mounted wireless communication unit receives the information of starting the engine or other power supply devices for ventilation returned by the mobile information interaction terminal, the control unit sends out an instruction for starting the engine or other power supply devices, the ventilation execution unit is controlled to act by using energy provided by the engine or other power supply devices, the fresh air door is controlled to be opened, and fresh air with low temperature and clean outside the vehicle is introduced to ventilate and purify the closed passenger compartment.
The two ventilation methods, no matter a starting timer in timing ventilation or real-time monitoring of the temperature inside and outside the vehicle, all need the air conditioner controller to sleep and work in a low power consumption mode, which puts high requirements on comfortable CAN network management and static flow management, and improper treatment may cause storage battery feeding. In addition, if the user is just in two timing ventilation intervals when getting on the vehicle, the temperature in the vehicle is still high at the moment, and the effective cooling and ventilating effects are not achieved. And if the user uses the car again after this time at an interval of a long time, this timing ventilation or the inside and outside temperature of monitoring scheme of taking a breath will be meaningless, consume the accumulator jar electric quantity in vain, cause the battery feed risk, frequent initiative ventilation also can overuse the battery simultaneously and cause the battery life to reduce.
