Detailed Description
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, but not all, embodiments of the present application. 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 reference numbers in the present application are only used for distinguishing the steps in the scheme and are not used for limiting the execution sequence of the steps, and the specific execution sequence is described in the specification.
In order to solve the problems in the prior art, an embodiment of the present application provides a method for indicating a vehicle road driving, as shown in fig. 1, including the following steps:
104, determining a visual field area and a blind area in front of a vehicle corresponding to a driver according to vehicle information and the position of eyes of the driver, wherein the vehicle information comprises the width of the vehicle body, the length of a vehicle head and the position of a driving seat;
106, determining two intersection points of a boundary line of the visual field area and the blind area and a parallel line of the outer contour of the vehicle body corresponding to the width of the vehicle body;
Based on the solution provided by the foregoing embodiment, optionally, as shown in fig. 2, in step 102, acquiring a driving seat position of the vehicle and biometric information of the driver to determine an eye position of the driver, includes:
and step 206, determining the eye position of the driver according to the sitting posture height, the sitting posture and the three-dimensional coordinate position.
The vehicle driving seat position includes a height position of the seat surface in the vertical direction, a position of the center of the seat surface in the horizontal front-rear direction and the left-right direction, and the height position of the seat surface in the vertical direction and the positions of the center of the seat surface in the horizontal front-rear direction and the left-right direction are also the three-dimensional coordinate positions of the driving seat.
The biological characteristic information of the driver comprises the height of eyes of the driver from the buttocks when the driver sits normally, namely the sitting posture height of the driver relative to the surface of the driver seat, and the current sitting posture of the driver, wherein the sitting posture type comprises that the body of the driver sits on the driver seat in an upright mode, or the body leans forwards or leans against the back of the seat and the like.
The sitting posture height data of different drivers can be stored in the database, and after the driver sits on the driving seat, the image of the driver is obtained through the camera and recognized, so that the sitting posture height corresponding to the driver can be obtained from the database.
According to the absolute sitting posture height and the corresponding sitting posture of the driver and the three-dimensional coordinate position of the driving seat, the eye position of the driver after sitting down can be determined.
In step 104, the vehicle information includes the vehicle body width, the vehicle head length and the driving seat position corresponding to the target vehicle, and the vehicle information corresponding to different vehicles may be different, so that the relative eye position of the driver may also change after sitting on the driving seat. Accordingly, the driver can see different visual fields and blind areas outward through the windshield in front of the vehicle. The blind area is a vehicle head blind area, and a place which cannot be seen in front of a hood in front of a vehicle head is also called a front blind area and is related to the width of a vehicle body, the height of a seat, the length of the vehicle head and the eye position of a driver.
For example, a vehicle with a lower chassis and a lower driving seat position can see a larger visual field area in a vehicle with a higher chassis and a higher driving seat position by the same driver.
In step 106, referring to fig. 3, the boundary between the sight area and the blind area may be shown, and fig. 3 is a schematic view of an application scenario of the vehicle road driving indication method according to the embodiment of the present application, where the schematic view is a top view of a roof of a corresponding vehicle looking down.
As shown in fig. 3, the blind area is R1, the viewing area is R2, and the boundary between the viewing area R2 and the blind area R1 is D. When the driver seat is positioned on the left side of the vehicle, the boundary D is an asymmetric arc line, and the field of view on the left side is larger. The parallel line of the outer contour of the vehicle body corresponding to the width of the vehicle body comprises a first straight line 32 corresponding to the outer contour of the left side of the vehicle body and a second straight line 34 corresponding to the outer contour of the right side of the vehicle body. In the top view state, the eye position of the driver corresponds to the point 10.
Here, the vertical width of the parallel line of the outer contour of the vehicle body may be approximately 5-20cm greater than the actual width of the vehicle body. For example, the first line 32 of the left side outer contour of the vehicle body is offset to the left by 5-10cm relative to the widest part of the left side of the vehicle body, and the second line 34 of the right side outer contour of the vehicle body is offset to the outside by 5-10cm relative to the widest part of the right side of the vehicle body.
Optionally, in step 106, determining two intersection points of the boundary between the visual field area and the blind area and a parallel line of the outer contour of the vehicle body corresponding to the width of the vehicle body includes:
determining the position of the intersection of the boundary and the first straight line to obtain a first intersection point;
and determining the position of the intersection of the boundary line and the second straight line to obtain a second intersection point.
As shown in fig. 3, the boundary D intersects the first straight line 32 to obtain an intersection point a, and the boundary D intersects the second straight line 34 to obtain an intersection point B.
At step 108, a vehicle width indicating device, such as the vehicle width indicating device 20 shown in fig. 3, may be provided based on the two intersection points A, B determined at the above step and the eye position 10 of the driver. The vehicle width indicating device 20 may be provided at a target position in front of a driver on the vehicle. Optionally, the predetermined area comprises a vehicle dashboard or front windshield.
In one embodiment, the vehicle width indicating device includes a first vehicle width indicating device and a second vehicle width indicating device, and optionally, in step 108, the setting of the vehicle width indicating device at the target position in the predetermined area in front of the driver according to the two intersection points and the eye position of the driver includes: setting a first vehicle width indicating device at a first position in a preset area in front of a driver, wherein a reference point corresponding to the first vehicle width indicating device is located on a connecting line of the eye position of the driver and a first intersection point and is superposed with the first intersection point; and setting a second vehicle width indicating device to be located at a second position in a preset area in front of the driver, wherein a reference point corresponding to the second vehicle width indicating device is located on a connecting line of the eye position of the driver and the second intersection point and is coincided with the second intersection point.
As shown in fig. 3, the vehicle width indicator 20 is provided on a vehicle instrument panel, and includes a first vehicle width indicator 22 on the left side and a second vehicle width indicator 24 on the right side. The vehicle width indicating devices 22, 24 may be members having a predetermined size and shape, such as a coin-sized column having a certain color, and mainly serve as a visual indication for the driver. Of course, the present application is not limited to the above-described embodiments, and the vehicle width indicator may have other suitable shapes, sizes, and/or colors.
After the same driver sits on the driving seat, the eye position of the driver is basically fixed, and correspondingly, the boundary of the visual field area and the blind area corresponding to the driver is also fixed. In addition, the vehicle body outer contour parallel line is also fixed. Therefore, two intersection points of the boundary of the visual field area and the blind area and the parallel line of the outer contour of the vehicle body are basically fixed.
From the fixed driver eye position 10 and the position of intersection A, B, it can be determined that the position of connecting line 42 corresponding to eye position 10 and intersection a, and the position of connecting line 44 corresponding to eye position 10 and intersection B are also fixed. Line 42 corresponds to the driver's eye line pointing at intersection a, and line 44 corresponds to the driver's eye line pointing at intersection B. The location of intersection A, B is outside the vehicle in the driver's field of view, and if there are no obstructions or obstacles in front, then intersection A, B is located on the ground corresponding to the driver's field of view.
The first width indicating device 22 is disposed in a predetermined area in front of the driver, for example, on a dashboard of the vehicle, and according to the visual principle, when the eye position is fixed, the first width indicating device 22 is disposed at different positions, and the driver looks at the first width indicating device 22, and the corresponding reference point, that is, the visual image of the first width indicating device 22, falls on different positions.
In the embodiment of the present application, the first vehicle width indicating device 22 is disposed at a position such that the driver can see that the vehicle width indicating device 22 falls at the position of the intersection a, that is, on the ground of the visual field area outside the vehicle when viewing the vehicle width indicating device 22.
That is, the position of the first width indicating device 22 is set such that the reference point corresponding to the first width indicating device 22 falls on the line connecting the eye position of the driver and the intersection a and coincides with the intersection a.
Likewise, the position of the second vehicle width indicating device 24 may be set such that the reference point corresponding to the second vehicle width indicating device 24 falls on the line connecting the eye position of the driver and the intersection B and coincides with the intersection B.
As described above, the intersection A, B corresponds to the body width of the vehicle. In this way, along the parallel line of the first straight line 32 and the second straight line 34, the external object located in the visual field area inside the intersection point a and B in front of the vehicle will fall within the range of the vehicle width of the vehicle, and will form a driving obstacle for the vehicle, that is, if the external object, such as an external vehicle or an obstacle, is located inside the intersection points a and B, the external object will scratch or collide with the vehicle if the vehicle continues to drive forward.
In this way, by setting the reference point corresponding to the first vehicle width indicating device 22 to fall on the line between the eye position of the driver and the intersection point a and coincide with the intersection point a, the driver can predict whether the vehicle will scratch or collide with an external object on the left side by looking at the first vehicle width indicating device 22. On the visual line, if the reference point corresponding to the first vehicle width indicating device 22 intersects with an object outside the vehicle, a scratch or a collision may occur. If the reference point corresponding to the first vehicle width indicating device 22 does not intersect with the object outside the vehicle, scratch or collision cannot occur.
Similarly, by setting the reference point corresponding to the second vehicle width indicating device 24 to fall on the line connecting the eye position of the driver and the intersection point B and coincide with the intersection point B, the driver can predict whether the vehicle will scratch or collide with an external object on the right side by looking at the second vehicle width indicating device 24.
For example, in fig. 3, the object T1 outside the vehicle intersects the intersection B, and the driver visually views the second width indicating device 24 and finds that the visual image point corresponding to the second width indicating device 24 falls on the object T1. If the vehicle continues to travel forward, it will collide with the object T1.
For the object T2 outside the vehicle in fig. 3, there is no intersection with the intersection point a, and the driver visually views the first width indicating device 22 and does not find that the visual image point corresponding to the second width indicating device 22 falls on any object. If the vehicle continues to move forward, no collision accident occurs.
The above objects T1, T2 may be obstacles or external vehicles.
Based on the solution provided in the foregoing embodiment, optionally, in step 110, instructing the driver to control the road running of the vehicle according to the vehicle width indicating device includes: if the reference point corresponding to any one of the first vehicle width indicating device and the second vehicle width indicating device falls on an object outside the vehicle, indicating the driver to control the vehicle to drive in the direction deviating from the object; and if the reference points corresponding to the first vehicle width indicating device and the second vehicle width indicating device do not fall on the object outside the vehicle, indicating the driver to control the vehicle to normally run.
The above-mentioned off-object directional running includes steering running, deceleration running or stop running.
In the above-described embodiment, the first vehicle width indicating device and the second vehicle width indicating device are respectively provided on the left side and the right side of the corresponding vehicle. In other embodiments of the present application, only one vehicle width indicating device may be further disposed corresponding to the left intersection of the vehicle, so as to indicate that the driver predicts the scratch or collision condition between the vehicle and the left external object, thereby controlling the road running of the vehicle. Or only one vehicle width indicating device can be arranged corresponding to the right intersection point of the vehicle, so as to indicate that the driver predicts the scratch or collision condition of the vehicle and the external object on the right side, and thus the road running of the vehicle is controlled.
In the case where the seat position and the sitting posture of the driver are fixed for the same driver, the vehicle width indication device according to the embodiment of the present invention may be fixedly provided.
However, when there are a plurality of drivers or the positions of the drivers and the positions of the driver's seats vary for the same target vehicle, the position of the vehicle width indicator device also varies accordingly. Thus, the vehicle width indicating device can be movably provided. And moving the vehicle width indicating device in the preset area according to the two intersection points and the eye position of the target driver so as to set the vehicle width indicating device at the target position in the preset area in front of the target driver.
The vehicle width indicating device driven and controlled by the micro motor can be arranged on a preset area of the vehicle, so that the vehicle width indicating device can move left and right. Therefore, the vehicle width indicating device is moved to the corresponding target position according to the eye position of the driver and the two intersection points. The movable vehicle width indicating device can be arranged at the left side and the right side respectively and is used for indicating the driver to predict the road condition corresponding to the external objects at the left side and the right side of the vehicle respectively, or only one movable vehicle width indicating device can be arranged, the movable vehicle width indicating device is moved to the target position corresponding to the left side to be used for predicting the road condition at the left side of the vehicle by the driver, and the movable vehicle width indicating device is moved to the target position corresponding to the right side to be used for predicting the road condition at the right side of the vehicle by the driver.
In the embodiment of the application, the position of the eyes of a driver is determined by acquiring the position of a driving seat of a vehicle and the biological characteristic information of the driver; determining a visual field area and a blind area in front of a vehicle corresponding to a driver according to vehicle information and the position of eyes of the driver, wherein the vehicle information comprises the width of a vehicle body, the length of a vehicle head and the position of a driving seat; determining two intersection points of a boundary line of the visual field area and the blind area and a parallel line of the outer contour of the vehicle body corresponding to the width of the vehicle body; setting a target position of the vehicle width indicating device in a preset area in front of the driver according to the two intersection points and the eye position of the driver; the driver is instructed to control the road running of the vehicle according to the vehicle width indicating device, so that the vehicle width indicating device arranged at the target position provides visual vehicle outline reference for the driver, the driver accurately judges the vehicle outline width and the running track by observing the position of the vehicle width indicating device on the running road, and the driver is assisted to control the running of the vehicle on the road, thereby obviously improving the driving safety and convenience.
Particularly, when the vehicle approaches a narrow road, the embodiment of the application can avoid the situation that a driver scratches or collides with an external object due to the fact that the driver cannot accurately judge the outer contour of the vehicle, and accordingly safety of vehicle driving is further improved.
