Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a method for adjusting the position of a driving seat, which can solve the problems that the adjustment accuracy is poor and the universality is to be improved due to the fact that the individual differences of different drivers are not fully considered in the related art.
Referring to fig. 1, the adjusting method includes the steps of firstly, judging whether a driver is on a driving seat, if so, obtaining angle information of a backrest of the driving seat, judging whether the angle information is within a preset angle range, and if not, adjusting the angle of the backrest of the driving seat until the angle of the backrest of the driving seat is within the preset angle range; then acquiring position state information of a driver on the driving seat, calculating the actual eye position of the driver according to the position state information, judging whether the actual eye position is located in the eye preset area, and if not, calculating the difference value between the actual eye position and the eye preset area; and finally, adjusting the actual eye position according to the difference value, and adjusting the actual eye position for multiple times in a gradual approximation mode according to the change condition of the difference value in the adjusting process until the actual eye position is located in the preset eye area.
Specifically, the adjusting method firstly determines whether a driver is in the driving seat, if so, the driver is about to start driving, and then adjusts the backrest of the driving seat according to the current angle information of the backrest so that the backrest is adjusted to be within the preset angle range, because after the angle is determined, the driving seat only needs to be adjusted along the length direction and the height direction of the vehicle, and therefore once the angle adjustment of the backrest of the driving seat is determined, the subsequent adjustment does not influence the angle of the backrest of the driving seat. And finally, adjusting the actual eye position according to the difference, and adjusting the actual eye position in a gradual approximation manner according to the change condition of the difference in the adjusting process until the actual eye position is located in the eye preset area.
Whole accommodation process is progressive, can guarantee the precision of regulation as far as possible, can help the driver to obtain the best field of vision when driving, improve and drive the travelling comfort, reduce the safety risk that leads to because driver field of vision problem, and the individual difference of different drivers has fully been considered, according to current driver's size characteristics, carry out the adjustment of pertinence, when guaranteeing that any driver drives on driving seat, it homoenergetic sees the best driving field of vision, it is good to possess the advantage that the regulation accuracy is good, the commonality is good. The first point is that the two hands of the driver can be naturally lapped on the uppermost part of the steering wheel to ensure that the elbow is provided with certain bending, the bending can still be kept when the steering wheel is held by hands to rotate 180 degrees, and the bending angle is controlled to be about 120 degrees; the second point is that after the right foot fully steps on the brake pedal, the knee still has certain bending, and the bending angle is about 120 degrees; the third point is that the sun shield does not block the view of the driver when being put down.
The eyes preset area is a certain area space which is obtained comprehensively by considering the driving comfort of the driver and combining calculation according to internal structure parameters of different vehicle types under the condition that the driver sits well in position, holds a steering wheel with two hands and places the right foot at a braking position and comparison with a driver optimal view database. In particular, reference is made to the regulation of the distance E between the right and left eye of a human eye 1 E 2 65mm, human eyeball E 1 E 2 The distance between the horizontal line and the neck P is 98mm, the horizontal eyeball visual angle is 60 degrees, the upper visual angle and the lower visual angle are respectively 45 degrees and 65 degrees, the rotatable left angle and the rotatable right angle of the neck P are both 60 degrees, and the optimal visual field area value, namely the eye preset area, is obtained through the self-adaptive calculation of the parameter system.
After the driver is monitored to be in the driving seat, because the driver is not in the posture ready for driving when sitting on the seat, if the actual eye position is directly determined by the position state information of the driver at the moment, the actual eye position may not be the position of the final actual driving. Therefore, as shown in fig. 2, after obtaining the position state information of the driver on the driving seat, the adjusting method further includes determining whether the head of the driver is completely located in the head preset region according to the position state information, if so, calculating the actual eye position of the driver according to the position state information, if not, calculating the overlap percentage of the head of the driver and the head preset region according to the position state information, determining whether the overlap percentage is smaller than the preset percentage, and if so, sending an early warning signal until the overlap percentage is greater than or equal to the preset percentage. Specifically, before confirming the actual eye position of the driver, whether the driver sits well in the posture of driving in advance is judged by confirming the head position of the driver, the head preset area is the middle area of the upper part of the seat, whether the driver sits well normally at the moment can be judged by calculating the overlapping percentage of the head of the driver and the head preset area, if the head of the driver is displayed to deviate from the head preset area too seriously, the vehicle can send out an early warning signal to remind the driver to correct the position, then the actual eye position of the driver is obtained, and the smoothness and the accuracy of the adjusting process are ensured.
Further, the difference value between the actual eye position and the eye preset region includes a height difference value between the actual eye position and the eye preset region in the vehicle height direction, and a horizontal difference value in the vehicle length direction.
Further, referring to fig. 3, the actual eye position is adjusted according to the difference, and the actual eye position is adjusted multiple times in a gradual approximation manner according to the variation of the difference during the adjustment process, which mainly includes the steps of:
determining distance values which are adjusted for the first time along the height direction and the length direction of the vehicle respectively according to the height difference value and the level difference value;
after the first adjustment is finished, re-determining the current height difference value and the current level difference value, and re-determining the distance values which are adjusted respectively along the height direction and the length direction of the vehicle at present according to the current height difference value and the current level difference value;
and so on, the actual eye position is adjusted multiple times in a stepwise approximation.
Specifically, in order to ensure the adjustment accuracy, after the difference is determined and before the adjustment is started, the distance values to be adjusted for the first time in the height direction and the length direction of the vehicle are determined according to the height difference and the level difference, the distance values to be adjusted for the first time are related to the current height difference and the current level difference and are in a proportional relation, if the difference is larger, the distance to be adjusted for a single time is correspondingly larger, and if the difference is smaller, the distance to be adjusted for a single time is correspondingly smaller. Similarly, in the continuous adjusting process, the height difference value and the level difference value are continuously reduced, the actual eye position is gradually close to the eye preset area, the distance value of each adjustment is continuously adjusted in the process, and the actual eye position is adjusted for multiple times in a gradual approximation mode until the actual eye position is located in the eye preset area.
Further, whether the height difference value or the level difference value is within a first difference value range or not is judged, if yes, the value range of the corresponding distance value which is currently adjusted is 8-10 cm/time, if not, whether the height difference value or the level difference value is within a second difference value range or not is judged, if yes, the value range of the corresponding distance value which is currently adjusted is 5-7 cm/time, if not, whether the height difference value or the level difference value is within a third difference value range or not is judged, and if yes, the value range of the corresponding distance value which is currently adjusted is 2-4 cm/time.
Since the determined eye preset area is a range, that is, as long as the actual eye position is located in the eye preset area, the driver can obtain the optimal driving visual angle, as the driver inevitably experiences slight deviation in the driving process, if the adjusted actual eye position is exactly located at the boundary of the eye preset area or is very close to the boundary of the eye preset area, the actual eye position will move out of the eye preset area as long as slight deviation is achieved in the driving process, in order to ensure that the driver always has the optimal driving visual field in normal driving, further, as shown in fig. 4, until the actual eye position is located in the eye preset area, the steps include: if the actual eye position is located in the eye preset area, respectively calculating the minimum height difference value and the minimum horizontal distance of the actual eye position and the boundary of the eye preset area along the height direction and the length direction of the vehicle, respectively, and respectively judging whether the minimum height difference value and the minimum horizontal distance are greater than the minimum preset distance, if not, adjusting the actual eye position towards the corresponding direction until the minimum height difference value and the minimum horizontal distance are both greater than the minimum preset distance.
Further, whether a driver is on the driving seat or not is judged, and the steps mainly comprise:
acquiring a starting state of the vehicle, and acquiring a pressure value of a driving seat if the starting state is starting;
and judging whether the pressure value is greater than a preset pressure value, if so, judging that a driver is on the driving seat.
Specifically, when having the driver on driving seat, driving seat probably can bear certain pressure, consequently can judge whether have the driver on driving seat through the pressure sensor who sets up on driving seat, in some other embodiments, except adopting pressure sensor's mode to monitor, can also monitor through the mode that sets up the camera.
Furthermore, the position state information of the driver on the driving seat is acquired by the camera, and the position state information refers to a form that the camera converts the acquired human body image into coordinates through conversion, so that subsequent calculation and adjustment are facilitated.
Further, the value range of the preset angle range is 90-120 degrees.
The application also provides a device for adjusting the position of the driving seat, which is used for implementing the method for adjusting the position of the driving seat, and the device mainly comprises an information acquisition module, an information judgment module and an information execution module, wherein the information acquisition module is used for acquiring angle information of a backrest of the driving seat and position state information of a driver on the driving seat; the information judgment module is used for judging whether a driver is on the driving seat or not, judging whether the angle information is located in a preset angle range or not according to the angle information, calculating the actual eye position of the driver according to the position state information and judging whether the actual eye position is located in an eye preset area or not; the information execution module is used for adjusting the angle of the backrest of the driving seat according to the judgment result of the information judgment module so that the angle of the backrest of the driving seat is within a preset angle range, calculating the difference value between the actual eye position and the eye preset area according to the judgment result of the information judgment module, and adjusting the actual eye position for multiple times in a gradual approximation mode according to the change condition of the difference value so that the actual eye position is within the eye preset area.
