In this embodiment, through associating seat and rear-view mirror, the state at the seat changes the back at every turn, and the automatic control rear-view mirror corresponds the removal, realizes the follow-up regulation of automatic seat of rear-view mirror to need not the user and all need manual control adjustment rear-view mirror after adjusting the seat at every turn, improved automobile driving's convenience, be favorable to promoting user experience. Based on this, in order to realize the intelligent regulation of the rearview mirror, the invention also designs the following scheme:
and in the control process of the rearview mirror, matching corresponding rearview mirror adjusting parameters (a user height set value and a rearview mirror vision set value) from the preset control database according to the identity information (the driver ID) and the seat data, so as to adjust the state of the rearview mirror according to the rearview mirror adjusting parameters, and enable the vision of the rearview mirror to accord with the current seat state and the preference of the user.
Therefore, compared with the independent control of the traditional rearview mirror, the embodiment of the invention has active adaptability on the basis of automatically adjusting the rearview mirror, and considers that the positions of the seats closely related to the rearview function can cause frequent changes of the mood of consumers due to seasons, use in daytime and at night, and poor road surfaces of mountainous cities, so that the visual effect of the rearview mirror is possibly inconsistent with the use habits of the users when the state of the seats is adjusted by the consumers, and the state of the rearview mirror needs to be adjusted again. When a user controls the rearview mirror through a button or a touch screen on the automobile to adjust the state, the rearview mirror adjustment parameters need to be updated according to the active adjustment state of the rearview mirror, so that the view of the rearview mirror is corrected, the view preference and the optimal height value of the user are intelligently identified, the rearview mirror is automatically adjusted, and the use convenience and the vehicle using experience of the rearview mirror are improved.
In the embodiment of the invention, it can be understood that the preset control database is established under different seat data and rearview mirror data according to the height and leg length proportion standard of a normal person; the controller can obtain height information according to the identity information (driver ID) of the driver, and deduces the rearview mirror view set value preferred by the driver according to the seat data (front-back direction adjusting data, up-down direction adjusting data and back inclination angle adjusting data) checked by the automobile sensor device, thereby obtaining the adjusting parameter of the rearview mirror according to the rearview mirror view set value table look-up. As an example, the preset control database is shown in table 1.
TABLE 1 control database
Based on the embodiment, in order to intelligently adapt to the situations of randomness of height entry, difference of stature proportion, different views and different preferences in different periods and the like, the embodiment of the invention has active adaptation capability, can fully consider the stature proportion of a person, and performs active learning adjustment. Specifically, as shown in fig. 2, in step S104, after the rearview mirror control mechanism receives the active adjustment information of the user, the active adjustment state of the rearview mirror is recorded, and the rearview mirror adjustment parameter corresponding to the identity information and the seat data is updated according to the active adjustment state of the rearview mirror, specifically:
the active adjustment information includes: a first active adjustment signal;
s201, recording the active adjustment state of the rearview mirror after the rearview mirror control mechanism actively adjusts the rearview mirror according to the received active adjustment information;
s202, updating a rearview mirror view set value and/or a user height set value in rearview mirror adjusting parameters corresponding to the identity information and the seat data according to the active adjusting state of the rearview mirror.
In this embodiment, after the driver gets on the vehicle and starts the vehicle, the controller will execute the above steps S101 and S103 to automatically adjust the state of the rearview mirror.
After the state of the rearview mirror is automatically adjusted, if the user is not satisfied with the current state of the rearview mirror, the rearview mirror is adjusted to the state favored by the user through a rearview mirror adjusting key, a touch screen, voice control and the like of the automobile, so that the active adjustment of the state of the rearview mirror by the consumer is realized, and then the automobile learns and corrects the rearview mirror adjusting parameters. As shown in table 2 below, in No.2, the current seat state is maintained, and the user updates the rearview mirror adjustment parameters based on the active adjustment state of the rearview mirror for the first time when adjusting the rearview mirror, where the rearview mirror adjustment parameters mainly include a user height setting value and a rearview mirror view setting value.
Referring to fig. 3 and 5, in the case that the user does not adjust the seat, the current optimal rearview mirror view setting and/or the user height setting are calculated according to the unsatisfactory active correction setting of the user for the automatically adjusting rearview mirror service, so as to be a preferred scheme, step S202 is specifically designed as follows:
s301, judging whether the automatic adjustment parameter of the automatic adjustment rearview mirror is equal to 1;
s311, when the automatic adjusting parameter is not equal to 1, obtaining a rearview mirror visual field preference value of a user according to the active adjusting state of the rearview mirror recorded by the current active adjusting rearview mirror;
s312, updating the rearview mirror view preference value to a rearview mirror view set value in a rearview mirror adjustment parameter corresponding to the identity information and the seat data, and clearing the automatic adjustment parameter;
s321, when the automatic adjusting parameter is equal to 1, obtaining a rearview mirror visual field preference value and a user height set value of a user according to the state of the rearview mirror recorded by the current active adjusting rearview mirror and the state of the rearview mirror recorded by the last active adjusting rearview mirror;
and S322, correspondingly updating the rearview mirror visual field preference value and the height estimation value into a rearview mirror visual field set value and a user height set value in a rearview mirror adjustment parameter corresponding to the identity information and the seat data respectively, and resetting the automatic adjustment parameter.
In the present embodiment, for the convenience of understanding and application of those skilled in the art, it should be noted that, regarding steps S321 and S322, in the first use situation after the customer purchases the vehicle, if the customer does not readjust the rearview mirror, and then the automatically adjusting rearview mirror operation occurs due to the seat adjustment, the system defaults to the stored rearview mirror & seat values as the acceptable active adjustment behavior of the customer. Then, when the consumer is not satisfied with the first automatic adjustment of the situation, the operation of actively adjusting the rearview mirror is performed, and the controller matches the result of the current active adjustment with the factory setting value so as to correct the rearview mirror view setting value and the user height setting value in the rearview mirror adjustment parameters. In the situation that the automobile is not used for the first time, the system corrects the rearview mirror view set value and the user height set value in the rearview mirror adjustment parameter according to the state of the rearview mirror recorded by the current active adjustment rearview mirror and the state of the rearview mirror recorded by the last active adjustment rearview mirror.
Referring to fig. 4 and 5, in the case that the user adjusts the seat, the currently best rearview mirror view setting value and/or user height setting value are calculated according to the active correction setting that the user is dissatisfied with the service of automatically adjusting the rearview mirror twice, so as to be preferable, step S202 may be further specifically designed as:
s401, judging whether an automatic adjusting parameter of the automatically adjusted rearview mirror is more than or equal to 2, wherein the automatic adjusting parameter is increased by 1 when the rearview mirror is automatically adjusted along with seat adjustment each time;
s411, when the automatic adjusting parameter is more than or equal to 2, obtaining a rearview mirror visual field preference value of a user according to the active adjusting state of the rearview mirror recorded by the current active adjusting rearview mirror;
s412, updating the rearview mirror view preference value to a rearview mirror view set value in a rearview mirror adjustment parameter corresponding to the identity information and the seat data, and resetting the automatic adjustment parameter;
s421, when the automatic adjusting parameter is less than 2, obtaining a rearview mirror visual field preference value and a user height set value of a user according to the state of the rearview mirror recorded by the current active adjusting rearview mirror and the state of the rearview mirror recorded by the last active adjusting rearview mirror;
s422, the rearview mirror visual field preference value and the height estimation value are correspondingly updated to a rearview mirror visual field set value and a user height set value in a rearview mirror adjusting parameter corresponding to the identity information and the seat data respectively, and the automatic adjusting parameter is cleared.
In this embodiment, after the first correction, the user adjusts the seat so that the rearview mirror is automatically adjusted, and if the user is still not satisfied with the current state of the rearview mirror, the rearview mirror is controlled to be adjusted to the state preferred by the user through the rearview mirror adjustment button or the touch screen of the automobile, so as to manually correct the state of the rearview mirror. Referring to the data No.4 shown in table 2, the current seat state is maintained, and the user adjusts the rearview mirror for the second time, so that the active adjustment state of the rearview mirror is changed to rearview mirror adjustment parameters, wherein the rearview mirror adjustment parameters include a user height setting value and a rearview mirror view setting value.
TABLE 2 seat adjustment, rearview mirror adjustment parameters and corresponding comments
With continued reference to table 2, the following describes the logic of the inventive control of the rearview mirror:
first automatically adjusting rearview mirror of automobile: after the automobile is awakened and started, the controller matches corresponding rearview mirror adjusting parameters from the preset control database according to the identity information of the driver and the real-time detected seat data, so that the state of the rearview mirror is adjusted according to the rearview mirror adjusting parameters. The height setting value of the user obtained according to the identity information of the driver is C1, the rearview mirror vision setting value is D1, the rearview mirror adjustment parameter at the moment is the height vision setting value (C1, D1), the corresponding current rearview mirror state is (A1, B1), and the current seat state is (X1, Y1, Z1).
First active adjustment of the rearview mirror by the user: if the user is unsatisfied with the current state of the rearview mirror, the rearview mirror is controlled to be adjusted to the state preferred by the user through a rearview mirror adjusting key or a touch screen of the automobile, so that the state of the rearview mirror is manually corrected, the current state of the rearview mirror is (A2 and B2), the corresponding current state of the seat is (X1, Y1 and Z1), the height set value of the user is kept to be C1, the rearview mirror vision set value in rearview mirror adjusting parameters needs to be updated to be D2, and the adjusting effect of updating the vision angle of the user is achieved.
Second automatically adjusting rear-view mirror of the automobile: when the user adjusts the seat state, the controller extracts rearview mirror adjusting parameters from the preset control database according to the seat data and the identity information, height view setting values in the rearview mirror adjusting parameters are (C1, D2), corresponding rearview mirror states are (A3, B3) obtained by looking up a table according to (C1, D2) and the current seat state as (X2, Y2, Z2), and then the rearview mirror states are adjusted by taking (A3, B3) as a reference. The angle of the rearview mirror is actively adjusted according to the seat data on the basis of maintaining the previous C1 and D2, so that the effect of linkage adjustment of the rearview mirror along with the change of the seat is achieved.
Second active adjustment of the user rearview mirror: if the current state of the rearview mirror is still unsatisfied by the user, the state of the rearview mirror is controlled to be in a state preferred by the user through a rearview mirror adjusting key or a touch screen of the automobile, so that the state of the rearview mirror is manually corrected, the current state of the rearview mirror is (A4, B4), the corresponding current state of the seat is (X2, Y2, Z2), at the moment, due to the fact that the current state of the rearview mirror is unsatisfied by two times before and after the current state of the rearview mirror, the current optimal height visual field is deduced to be set to be C3 based on the last time of rearview mirror adjustment result and the current time of rearview mirror adjustment result, the set value of the rearview mirror visual field is D3, and rearview mirror adjustment parameters (C3, D3) are used.
……
Then, if the user does not perform manual adjustment after more than two times of automatic adjustment rearview mirror services, the controller determines that the height and the rearview mirror visual field are correctly determined, then the optimal height calculated according to the estimation is set as C3, the rearview mirror visual field set value is D3 and is used as the corrected height angle value of the consumer, the optimal height is updated to rearview mirror adjustment parameters (C3 and D3), and the subsequent automatic adjustment rearview mirror operation is used for realizing the linkage control of the seat and the rearview mirror according to the rearview mirror adjustment parameters (C3 and D3).
In one possible embodiment of the present invention, the optimal height setting value is calculated by using the current adjustment result and the previous adjustment result. And establishing a complete data model containing all feasible data combinations of the seat rearview mirrors with the same view field and the same height in the control database. When the preference of the consumer is two sets of different seat rearview mirror data, the look-up table comparison can be carried out so as to calculate the height and the visual field value.
TABLE 3 estimation of corresponding heights in the control database
As shown in table 3, in the adjustment data of No.3, the seat data is (X3, Y3, Z3), the mirror state is (A3, B3), and the height field value set by the controller is (CX, DX) (not the true C, D value).
In the subsequent NG adjustment, when the seat position is adjusted to (X6, Y6, Z6), the position of the mirror obtained by table lookup is adjusted to (AM, AN) data based on the table data corresponding to (CX, DX).
If the consumer adjusts to (A6, B6) according to the real preference, the controller will judge the height and view field actively, and use the height and view field combined value C, D that the two data of NO.3 (X3, Y3, Z3), (A3, B3) and NO.6 (X6, Y6, Z6), (A6, B6) are in line with as new control reference, to calculate the optimal height.
It is understood that it is impossible to derive a plurality of combinations of height and field of view from the No.3 data and No.6 data because the position and rearview mirror changes are linear for different preferences of height and field of view, so that two sets of data can derive a unique combination of height and field of view.
The method for controlling the rearview mirror of the automobile provided by the first embodiment of the invention fully considers the figure proportion of people and carries out active learning and adjustment, and the active adaptation control logic is shown in fig. 5:
after the automobile is awakened, the controller acquires the identity information and the seat data of the driver, and extracts the rearview mirror adjustment parameters (assuming the height set value C of the consumer) corresponding to the identity information and the seat data from a preset control database1And a visual field setting value D1) Therefore, the rearview mirror adjusting parameters matched with the current seat state are obtained, and the automobile can automatically adjust the angle of the rearview mirror according to the seat state.
When the consumer does not adjust the seat state, if the consumer is not satisfied with the current rearview mirror angle, the active adjustment operation (such as mechanical key/touch screen key operation, voice control, direct adjustment of the rearview mirror by hand) is performed on the rearview mirror, so that the view angle of the rearview mirror meets the requirements or preferences of the consumer. After judging that the consumer performs the operation of actively adjusting the rearview mirror, the controller further judges whether the automatic adjustment parameter is equal to 1:
when the auto-adjust parameter is not equal to 1, then the controller will maintain the height setting C of the consumer1The vision set value D of the rearview mirror is corrected by the state of the rearview mirror after the consumer actively adjusts the rearview mirror operation1Is changed to D2And meanwhile, clearing 0 the automatic adjustment parameters. When the automobile automatically adjusts the rearview mirror, the parameters (height set value C of the consumer) are adjusted according to the rearview mirror1And a visual field setting value D2) The rearview mirror is automatically adjusted.
When the automatic adjusting parameter is equal to 1, the current rearview mirror angle is still unsatisfied by the consumer, the active adjusting operation is continuously carried out on the rearview mirror, the view angle of the rearview mirror is made to accord with the current requirement or preference of the consumer, and the controller judges the height set value C of the consumer1And a visual field setting value D2If the conditions are inaccurate, a new condition needs to be calculated according to the state of the rearview mirror actively adjusted by the consumer this time and the state of the rearview mirror actively adjusted last timeHeight setting value C of consumer3And a visual field setting value D3And meanwhile, clearing 0 the automatic adjustment parameters. When the automobile automatically adjusts the rearview mirror, the parameters (height set value C of the consumer) are adjusted according to the rearview mirror3And a visual field setting value D3) The rearview mirror is adjusted.
When the consumer adjusts the seat state, the controller recognizes the seat data changed after the consumer adjusts the seat state, and the controller automatically looks up the table according to the adjusted seat data and based on the identity information (driver ID) of the consumer to obtain the rearview mirror adjustment parameter (assuming the height setting value C of the consumer)1And a visual field setting value D1) The mirror state is adjusted in this way, and each time the mirror is automatically adjusted, the mirror state is automatically adjusted by + 1. Thus, linkage control of the seat and the rearview mirror is realized, and the visual field of the rearview mirror is in accordance with the current seat state.
After the rearview mirror is automatically adjusted, if the current rearview mirror angle is not satisfied by a consumer, the rearview mirror is actively adjusted, so that the view angle of the rearview mirror meets the current requirement or preference of the consumer; it will be appreciated that in one implementation, if the vehicle is operated by a button/touch screen or controlled by voice, the vehicle will generate mirror adjustment commands to determine the active adjustment of the rearview mirror by the consumer. After judging that the consumer actively adjusts the rearview mirror, the controller further judges whether the automatic adjusting parameter is more than or equal to 2:
when the automatic adjusting parameter is more than or equal to 2, the controller maintains the height set value C of the consumer1The vision set value D of the rearview mirror is corrected by the state of the rearview mirror after the consumer actively adjusts the rearview mirror operation1Is changed to D2And meanwhile, clearing 0 the automatic adjustment parameters. When the automobile automatically adjusts the rearview mirror, the parameters (height set value C of the consumer) are adjusted according to the rearview mirror1And a visual field setting value D2) The rearview mirror is automatically adjusted.
When the automatic adjustment parameter is not more than or equal to 2, the consumer is still dissatisfiedThe angle of the front rearview mirror is continuously actively adjusted to ensure that the view angle of the rearview mirror meets the current demand or preference of the consumer, and the controller judges the height set value C of the consumer1And a visual field setting value D2If the height setting value C is inaccurate, a new height setting value C of the consumer needs to be calculated according to the state of the rearview mirror actively adjusted by the consumer at this time and the state of the rearview mirror actively adjusted last time3And a visual field setting value D3And meanwhile, clearing 0 the automatic adjustment parameters. When the automobile automatically adjusts the rearview mirror, the parameters (height set value C of the consumer) are adjusted according to the rearview mirror3And a visual field setting value D3) The rearview mirror is adjusted.
