Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The air condition in the vehicle cabin directly affects the physical health of the driver and the passengers, has non-negligible influence on the driving safety, and particularly in some special driving conditions, such as the way to travel to higher or lower altitudes, the change of the oxygen concentration in the vehicle cabin can directly cause uncomfortable symptoms such as hypoxia or drunk oxygen of the driver and the passengers.
The existing solution is to maintain the oxygen concentration in the cabin at a certain level by means of an oxygen regulating device in the vehicle, and the method improves the comfort of passengers to a certain extent, but after passengers get off or turn off the oxygen regulating device, the passengers need an external oxygen environment which is completely different from the internal oxygen environment on the straight surface, and the passengers in the vehicle do not adapt to the process and still generate discomfort.
The application provides an in-vehicle oxygen concentration control method, which has a transition mode, can improve the in-vehicle oxygen concentration control process under the condition of changing the in-vehicle oxygen environment, and realizes the transition process from the in-vehicle oxygen environment to the out-vehicle oxygen environment.
As shown in fig. 1, in one embodiment, the method comprises the steps of:
It should be noted that the oxygen concentration referred to in the present application may be understood as the oxygen mass in the unit space, the value of which is related to the altitude, and in this embodiment, the first oxygen concentration and the second oxygen concentration are detected by oxygen concentration sensors provided outside the vehicle cabin and inside the vehicle cabin, respectively.
In the actual implementation process, the first oxygen concentration change rate is obtained by continuously detecting the oxygen concentration outside the vehicle cabin and dividing the difference value of the oxygen concentration between the front and rear times by the time difference, and the first oxygen concentration change rate takes absolute value form in the previous calculation mode to participate in the subsequent calculation, wherein the larger the value is, the more severe the change of the oxygen concentration outside the vehicle cabin is represented.
It will be appreciated that the vehicle will generally maintain a substantially steady external oxygen environment within the cabin, and that even if there is a slight change in the oxygen environment during travel of the vehicle, interference may be removed by filtering the sensor signal or the like, and thus a typical value for the first rate of change threshold may be zero.
Illustratively, as the altitude increases during the travel of the vehicle to a higher altitude area, the first concentration of oxygen outside the vehicle cabin, i.e., the first oxygen concentration, decreases, and the first concentration change rate is greater than zero, i.e., the first target change rate, which in this application is the desired change rate of oxygen concentration inside the vehicle cabin, may be determined from the first concentration change rate.
In the actual implementation process, the first target change rate is associated with the first concentration change rate, for example, the first target change rate and the first concentration change rate may be a positive correlation relationship, a preset mapping correspondence relationship, or a stepwise jump relationship.
The adjustment process of the present application is described with the vehicle traveling to a higher altitude area as an example: because the oxygen concentration outside the vehicle cabin (first oxygen concentration) is reduced, the oxygen in the vehicle cabin is reduced due to the influence of the outside, and under the condition of no measure intervention, the reduction rate of the oxygen concentration in the vehicle cabin is approximately equal to that of the outside of the vehicle cabin, and the oxygen deficiency reaction of personnel in the vehicle is likely to occur; if the oxygen concentration in the vehicle is ensured by adopting a stable maintenance mode, the passenger will be in a straight low-concentration oxygen environment after getting off.
According to the control method, under the condition that the external oxygen concentration is reduced, the second oxygen concentration is reduced according to the expected first target change rate by controlling the oxygen supply parameter of the oxygen supply device, such as the oxygen supply rate, and the first target change rate is smaller than the first concentration change rate, so that the oxygen concentration in the vehicle cabin is reduced more slowly, and passengers can adapt to the low-oxygen environment gradually.
Illustratively, when the first oxygen concentration decreases, the in-vehicle controller obtains a first target concentration, which is a desired in-vehicle concentration value at the next time, based on the second oxygen concentration at the current time and the first target rate of change. And controlling the oxygen supply parameter of the oxygen supply device according to the first target concentration by adopting a feedback control method based on the current value and the target value as input, so that the second oxygen concentration is close to or equal to the first oxygen concentration.
Exemplary description of the adjustment process of the travel of the vehicle to the lower altitude area: in this process, the first oxygen concentration is increased and the second oxygen concentration is controlled by controlling the power parameters of the oxygen removal device, such as the nitrogen-filled exhaust device, to increase at a desired first target rate of change.
It will be appreciated that in the above adjustment process, the adjustment direction of the second oxygen concentration is kept identical to the change direction of the first oxygen concentration, i.e., the second oxygen concentration changes with the first oxygen concentration.
By adopting the method for controlling the oxygen concentration in the vehicle, the oxygen concentration in the vehicle cabin is subjected to transition regulation, so that the oxygen concentration is changed according to the target change rate which is smaller than the change rate of the oxygen concentration outside the vehicle cabin, the transition from the oxygen environment in the vehicle to the oxygen environment outside the vehicle is realized, and passengers can adapt to the change of the oxygen environment.
In one embodiment, the determination of the first target rate of change may be as follows:
1) A transition coefficient is determined, the transition coefficient being preset or obtained from a user input, and the transition coefficient being less than 1.
2) The first target rate of change is determined from a product of the transition coefficient and the first concentration rate of change.
In the actual implementation process, the vehicle-mounted controller determines that the external oxygen environment of the vehicle cabin changes by monitoring the first oxygen concentration, and CAN send a signal to an IVI (In-vehicle information entertainment system) network through a CAN (controller area network) network, the IVI controls a speaker In the vehicle to sound and inquire whether an occupant In the vehicle enters a transition mode or not, and after receiving a reply voice confirmed by the occupant, the IVI sends a signal to the vehicle-mounted controller through the CAN to enter the transition mode, and an IVI popup window or a voice prompt user sets the transition coefficient. The transition coefficient is an important parameter for determining the change rate of the oxygen concentration in the vehicle, and the user can set the value of the transition coefficient according to the physical condition after hearing a voice prompt or a large screen with a popup prompt. The range may be set, for example, to 0.1 to 0.9, with the larger the value, the closer the desired in-vehicle oxygen change rate is to the outside of the vehicle, the smaller the value, and the longer the in-vehicle oxygen concentration reaches a value consistent with the outside of the vehicle oxygen concentration. If not set for a certain period of time, the system adopts a default value, for example, 0.8.
In the above embodiment, the oxygen concentration inside the cabin may be gradually reduced at a smaller rate in the implementation process, for example, as shown in a portion a of fig. 2, in fig. 2, a solid line OX1 indicates a first oxygen concentration, a broken line OX2 indicates a second oxygen concentration, in a portion B of fig. 2, the oxygen concentration outside the cabin is re-stabilized, and in the case that an oxygen concentration difference still exists between the inside and the outside of the cabin, the first concentration change rate falls below a first change rate threshold.
In one embodiment, the on-board controller further obtains a concentration difference from the first oxygen concentration and the second oxygen concentration; when the first concentration change rate is less than or equal to the first change rate threshold, and the concentration difference is greater than or equal to a concentration threshold, the second oxygen concentration is adjusted based on a second target change rate such that the second oxygen concentration is near or equal to the first oxygen concentration.
By monitoring the difference between the internal and external concentration of the vehicle cabin, the capability of adjusting the oxygen concentration in the vehicle cabin is still maintained after the oxygen concentration outside the vehicle cabin is re-stabilized, and in this embodiment, the second target change rate may be extended by the first target change rate at the time T1, or a calculated value such as a mean value of the first target change rates in the portion a, or a system preset value is adopted.
In some embodiments, after obtaining the concentration difference value according to the first oxygen concentration and the second oxygen concentration, the method further includes a step of calculating an estimated change time according to the concentration difference value and the first target change rate, and if the oxygen concentration outside the vehicle cabin tends to be stable, the estimated change time can be obtained by calculating the second target change.
And sending the estimated change time to a display terminal such as a vehicle-mounted display and the like for display, so that the passengers can select proper get-off time.
The method for controlling the oxygen concentration in the vehicle further discloses a control process under partial extreme conditions, such as when the vehicle falls into water, which is hereinafter referred to as an emergency maintenance mode, when the first concentration change rate is greater than a second change rate threshold value, the method enters the emergency maintenance mode, the second oxygen concentration is adjusted to a second target concentration and is maintained, and the second change rate threshold value is greater than the first change rate threshold value.
In an actual implementation process, the second rate threshold may be an oxygen concentration rate obtained through experiments under extreme conditions, for example, an oxygen concentration rate corresponding to a vehicle water falling scene.
The second target concentration is an oxygen concentration value suitable for human survival.
It can be appreciated that in the method for controlling the oxygen concentration in the vehicle provided by the application, the emergency maintenance mode can have the highest priority, and the life safety of the passengers is preferentially ensured.
In general, the vehicle is in a relatively stable external oxygen environment for a long period of time, and the in-vehicle oxygen concentration control may be applied to improve the comfort of the occupant's daily travel, which is hereinafter referred to as a comfort mode.
In some embodiments, the method for controlling the oxygen concentration in the vehicle provided by the application further comprises:
obtaining a second concentration change rate from the second oxygen concentration; and when the first concentration change rate is smaller than or equal to the first change rate threshold value and the second concentration change rate is larger than a third change rate threshold value, adjusting the second oxygen concentration to the first oxygen concentration.
The first concentration change rate is smaller than or equal to the first change rate threshold, and the condition that the oxygen environment outside the vehicle cabin is unchanged can be considered, but under the condition that the vehicle cabin is closed, the oxygen concentration in the vehicle cabin can be continuously reduced due to respiration of passengers, the third change rate threshold is determined according to a test, and when the oxygen concentration in the vehicle cabin is changed only, the inside and the outside of the vehicle cabin are adjusted to be consistent.
The in-vehicle oxygen concentration control method provided by the application also judges whether the target value is reached or not according to the actually collected second oxygen concentration, namely, the first oxygen concentration, if the target value is not reached, the oxygen output is continuously regulated to form closed loop regulation, and the time required for reaching the target value is calculated according to the current second concentration change rate and the target value, so that a user is reminded.
Referring to fig. 3, a flow chart of controlling oxygen concentration in a vehicle disclosed in an embodiment of the present application is shown, and in fig. 3, an implementation flow of an emergency maintenance mode, a transition mode and a comfort mode is illustrated by taking oxygen supply adjustment as an example, wherein a first change rate threshold value and a third change rate threshold value are both 0, monitoring of an oxygen environment in a vehicle cabin is further included before the transition mode adjustment, and the transition mode is started when a second concentration change rate is greater than zero, that is, when the oxygen concentration in the vehicle cabin is reduced.
On the other hand, the starting of the transition mode and the comfort mode can follow the instruction of the user, and the confirmation of the user requirement is realized through the voice interaction with the passengers.
