[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] The method for determining the parameters of a vehicle cab provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104, or it can be located in the cloud or on other network servers. The method for determining the parameters of the vehicle cab can be executed by terminal 102 or server 104, or it can be executed collaboratively by terminal 102 and server 104.

[0037] Taking the parameter determination method of the vehicle cab executed by terminal 102 as an example, terminal 102 establishes a front lower field of view model based on the first blind spot distance, side floor height, first front bulkhead parameters, and front overhang parameters in the first direction of the front lower field of view of the cab; terminal 102 establishes a human-machine comfort model based on driving comfort parameters and second front bulkhead parameters; terminal 102 merges the human-machine comfort model with the front lower field of view model to obtain a correlation model between front lower field of view and human-machine comfort; in response to the parameter determination request, terminal 102 establishes an equilibrium model based on the correlation model and the preset front bulkhead parameter values ​​and preset driving comfort parameter values ​​carried in the parameter determination request; the equilibrium model is used to reflect the relationship between the side floor height and the front bulkhead height; terminal 102 processes the parameter values ​​to be processed carried in the parameter determination request based on the equilibrium model to obtain the target parameter values; the parameter values ​​to be processed include the side floor height value to be processed or the front bulkhead height value to be processed, and the target parameter value is the target front bulkhead height value or the target side floor height value.

[0038] The terminal 102 can be a smartphone, tablet, laptop, desktop computer, smart speaker, smartwatch, IoT device, or portable wearable device. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle devices, etc. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices, etc.

[0039] Server 104 can be an independent physical server or a service node in a blockchain system, where the service nodes form a peer-to-peer network.

[0040] In addition, server 104 can also be a server cluster consisting of multiple physical servers, which can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0041] Terminal 102 and server 104 can be connected via Bluetooth, USB (Universal Serial Bus) or network, etc., and this application does not impose any restrictions.

[0042] In some embodiments, such as Figure 2 As shown, a method for determining parameters of a vehicle cab is provided. This method consists of... Figure 1 It can be executed by a server or terminal in the system, or by... Figure 1 The server and terminal in the process work together to execute the method. Figure 1 Taking the server execution in [the context of the example] as an example, the steps include:

[0043] Step 202: Based on the first blind spot distance, side floor height, first front bulkhead parameters, and front overhang parameters in the first direction, establish the front lower field of view model.

[0044] The forward downward field of vision is the driver's field of vision from the front and lower side while driving; due to the hardware design of the cab, there are some obstructed and invisible areas in the forward field of vision.

[0045] The side floor is the floor of the cab. The height of the side floor affects the driver's field of vision. Generally speaking, when the side floor is high, it will block the driver's downward view, thus reducing the driver's field of vision. When the side floor is low, the driver can see the position of the wheels and the road conditions more clearly, which can increase the field of vision.

[0046] The first direction can be the longitudinal direction of the vehicle, the same as the direction of the vehicle's movement; the second direction can be the perpendicular direction of the vehicle; the side floor height is the distance between the side floor and the ground in the second direction. In practical applications, the first direction can be represented by X, and the second direction by Z.

[0047] Front bulkhead parameters include those related to the front bulkhead (front sheet metal) of the cab, such as the front bulkhead height and the distance between the front bulkhead and the driver's position. These parameters also affect the driver's field of vision. Generally speaking, the higher the front bulkhead, the smaller the driver's field of vision; the lower the front bulkhead, the larger the driver's field of vision; the farther the distance between the front bulkhead and the driver's position, the smaller the driver's field of vision; and the closer the distance between the front bulkhead and the driver's position, the smaller the driver's field of vision.

[0048] Front overhang parameters are the horizontal distance between the center of the front wheels and the frontmost part of the vehicle. Front overhang parameters are usually set according to the required dimensions for installing the engine, radiator, steering system, and front suspension. Front overhang parameters also affect the driver's field of vision; the longer the front overhang parameter, the smaller the driver's field of vision, and the shorter the front overhang parameter, the larger the driver's field of vision.

[0049] In some embodiments, the server constructs a first right-angled triangle corresponding to the angle of the blind spot in the front lower field of vision using the first blind spot distance, the side floor height, the first front panel parameters, and the front overhang parameters, and determines the length of the first right-angled side and the length of the second right-angled side in the first right-angled triangle. Then, based on the length of the first right-angled triangle and the length of the second right-angled side, a front lower field of vision model reflecting the tangent value of the blind spot angle is constructed.

[0050] Specifically, the first front bulkhead parameters include front bulkhead-related parameters in the first direction and front bulkhead-related parameters in the second direction. Based on the front bulkhead-related parameters in the first direction and the first blind spot distance, the length of the first right-angle side corresponding to the front lower field of vision blind spot angle in the first direction is determined. Based on the front bulkhead-related parameters in the second direction and the side floor height, the length of the second right-angle side corresponding to the front lower field of vision blind spot angle in the second direction is determined.

[0051] Step 204: Establish a human-machine comfort model based on driving comfort parameters and second front bulkhead parameters.

[0052] The driving comfort parameters include: a first comfort distance X5 between the heel point and the positioning reference point in the first direction, a second comfort distance Z4 between the heel point and the positioning reference point in the second direction, a third comfort distance X6 between the eye point and the positioning reference point in the first direction, and a fourth comfort distance Z5 between the eye point and the positioning reference point in the second direction; the positioning reference point is also known as the ATRP (Accommodation Tool Reference Point).

[0053] The second front bulkhead parameters include the distance between the front bulkhead and the driver's position in the first direction, and the distance between the front bulkhead and the driver's position in the second direction.

[0054] In some embodiments, the server determines a first distance relationship based on a first comfort distance, a third comfort distance, and the distance between the front panel and the driver's position in a first direction; determines a second distance relationship based on a second comfort distance, a fourth comfort distance, and the distance between the front panel and the driver's position in a second direction; and establishes a human-machine comfort model based on the first distance relationship and the second distance relationship. This can be understood as the human-machine comfort model including the first distance relationship and the second distance relationship.

[0055] Step 206: The human-machine comfort model is fused with the forward lower field of vision model to obtain the correlation model between forward lower field of vision and human-machine comfort.

[0056] In some embodiments, the human-machine comfort model includes a first distance relationship and a second distance relationship. The first distance relationship represents the relationship between a first comfort distance, a third comfort distance, and the distance between the front bulkhead and the driver's position in a first direction. The second distance relationship represents the relationship between a second comfort distance, a fourth comfort distance, and the distance between the front bulkhead and the driver's position in a second direction.

[0057] The server substitutes the first and second distance relationships included in the human-machine comfort model into the forward downward field of vision model. Based on the first and second distance relationships, which represent the distance between the front panel and the driver's position in the forward downward field of vision model, a correlation model between the forward downward field of vision and human-machine comfort is obtained.

[0058] Step 208: In response to the parameter determination request, an equilibrium model is established based on the association model and the preset front bulkhead parameter values ​​and preset driving comfort parameter values ​​carried in the parameter determination request; the equilibrium model is used to reflect the relationship between the side floor height and the front bulkhead height.

[0059] The parameter determination request can be sent from the terminal to the server, and the parameter determination request carries preset front bulkhead parameter values ​​and preset driving comfort parameter values; the preset front bulkhead parameter values ​​and preset driving comfort parameter values ​​are parameter values ​​that are preset when designing the vehicle cab.

[0060] In some embodiments, in response to a parameter determination request, the server obtains the preset front bulkhead parameter value and the preset driving comfort parameter value carried in the parameter determination request, substitutes the preset front bulkhead parameter value and the preset driving comfort parameter value into the association model, performs numerical calculations on the association model after substituting the parameter values, and obtains the equilibrium model.

[0061] The equilibrium model reflects the relationship between the side floor height and the front bulkhead height, which can be a linear relationship, meaning that the side floor height and the front bulkhead height influence each other.

[0062] Step 210: Process the parameter values ​​to be processed carried in the parameter determination request based on the equilibrium model to obtain the target parameter values; the parameter values ​​to be processed include the side floor height value to be processed or the front panel height value to be processed, and the target parameter value is the target front panel height value or the target side floor height value.

[0063] The parameter determination request also carries parameters to be processed, which can be the height value of the side floor to be processed or the height value of the front panel to be processed; obviously, the preset front panel parameter value does not include the height value of the front panel to be processed.

[0064] The height value of the side floor to be treated or the height value of the front bulkhead to be treated are parameter values ​​preset when designing the vehicle cab.

[0065] The server takes the side floor height or front panel height value to be processed carried in the parameter determination request, substitutes it into the equilibrium model for numerical calculation, and obtains the target parameter value. It should be noted that when the parameter to be processed is the side floor height value, the target parameter value is the target front panel height value; that is, when the side floor height value is predetermined, the front panel height value can be calculated using the equilibrium model; when the parameter to be processed is the front panel height value, the target parameter value is the target side floor height value; that is, when the front panel height value is predetermined, the side floor height value can be calculated using the equilibrium model.

[0066] In the aforementioned method for determining the parameters of the vehicle cab, a forward lower field of vision model is established based on the first blind spot distance, side floor height, first front bulkhead parameters, and front overhang parameters in the first direction. A human-machine comfort model is established based on driving comfort parameters and second front bulkhead parameters. The human-machine comfort model is then fused with the forward lower field of vision model to obtain a correlation model between forward lower field of vision and human-machine comfort. In response to a parameter determination request, an equilibrium model is established based on the correlation model and the preset front bulkhead parameter values ​​and preset driving comfort parameter values ​​carried in the parameter determination request. The equilibrium model reflects the relationship between the side floor height and the front bulkhead height. The parameter values ​​to be processed carried in the parameter determination request are processed based on the equilibrium model to obtain target parameter values. The parameter values ​​to be processed include the side floor height value to be processed. The target parameter value is either the height of the front bulkhead or the height of the side floor. The driver's cab's forward downward visibility and driving comfort are combined to establish a correlation model between forward downward visibility and human-machine comfort. Based on this correlation model, preset front bulkhead parameter values, and preset driving comfort parameter values, a balance model is determined. Then, given the height of the side floor or the height of the front bulkhead to be processed, the target front bulkhead or the target side floor height is determined according to the balance model. This ensures that the target front bulkhead or the target side floor height is determined while comprehensively considering forward downward visibility and driving comfort. In other words, the determined vehicle cab parameters can achieve a larger forward downward visibility range while ensuring driving comfort, thus improving the accuracy of vehicle cab parameter determination.

[0067] In some embodiments, the first front bulkhead parameters include: front bulkhead height, first front bulkhead distance between the front bulkhead and the eye point in a first direction, second front bulkhead distance between the front bulkhead and the eye point in a second direction, and third front bulkhead distance between the front bulkhead and the wheel center in a first direction; establishing a front downward field of view model based on the first blind spot distance of the driver's cab in a first direction, the side floor height, the first front bulkhead parameters, and the front overhang parameters includes: determining the second blind spot distance of the driver's cab in a first direction based on the first blind spot distance of the driver's cab in a first direction, the front overhang parameters, the first front bulkhead distance, and the third front bulkhead distance; determining the third blind spot distance of the driver's cab in a first direction based on the side floor height, the front bulkhead height, and the first front bulkhead distance; and establishing a front downward field of view model based on the second blind spot distance and the third blind spot distance.

[0068] For example, the front bulkhead height Z2, the distance between the first front bulkhead and X4, the distance between the second front bulkhead and Z3, the distance between the third front bulkhead and X3, the distance between the first blind spot and X1, the side floor height Z1, and the front overhang parameter X2 are as follows: Figure 3 As shown.

[0069] The second blind spot distance can be determined based on the first blind spot distance X1, the front overhang parameter X2, the third front panel distance X3, and the first front panel distance X4. Specifically, the first sum of the first blind spot distance X1, the front overhang parameter X2, and the first front panel distance X4 is calculated, and the difference between the first sum and the third front panel distance X3 is calculated to obtain the second blind spot distance.

[0070] The third blind zone distance can be determined based on the side floor height Z1, the front panel height Z2, and the first front panel distance z3; specifically, the second sum of the side floor height Z1, the front panel height Z2, and the first front panel distance z3 is calculated, and the second sum is used as the third blind zone distance.

[0071] In some embodiments, establishing a forward lower field of vision model based on the second blind spot distance and the third blind spot distance includes: constructing a forward lower field of vision model that determines the tangent value of the forward lower field of vision blind spot angle based on the second blind spot distance and the third blind spot distance. The forward lower field of vision model is used to reflect the tangent value of the forward lower field of vision blind spot angle, providing a basis for subsequently associating the forward lower field of vision model with a human-machine comfort model.

[0072] It should be noted that the second blind spot distance is the length of the first right-angled side in the first right-angled triangle corresponding to the angle of the anterior inferior visual field blind spot, and the third blind spot distance is the length of the second right-angled side in the first right-angled triangle. Therefore, the ratio between the third blind spot distance and the second blind spot distance can be calculated to obtain the tangent value of the angle of the anterior inferior visual field blind spot.

[0073] For example, the frontal lower field of vision model is shown in Equation (1).

[0074] (1)

[0075] Wherein, the distance to the second blind zone = X1 + X2 - X3 + X4; the distance to the third blind zone = Z1 + Z2 + Z3; It is the angle of the frontal lower field of vision blind spot. The tangent value.

[0076] In the above embodiments, a forward downward field of view model is established by using the parameters of the cab that affect the forward downward field of view. This allows the process of determining the cab parameters to fully consider the forward downward field of view, thereby improving the forward downward field of view range corresponding to the determined cab parameters.

[0077] In some embodiments, driving comfort parameters include: a first comfort distance between the heel point and the positioning reference point in a first direction, a second comfort distance between the heel point and the positioning reference point in a second direction, a third comfort distance between the eye point and the positioning reference point in a first direction, and a fourth comfort distance between the eye point and the positioning reference point in a second direction; second front bulkhead parameters include: a first front bulkhead distance between the front bulkhead and the eye point in a first direction, a second front bulkhead distance between the front bulkhead and the eye point in a second direction, a fourth front bulkhead distance between the heel point and the front bulkhead in a first direction, and the front bulkhead height; based on the driver's driving comfort parameters and the second front bulkhead parameters, a human-machine comfort model is established, including: establishing a first distance relationship between the first front bulkhead distance, the first comfort distance, the fourth front bulkhead distance, and the third comfort distance; establishing a second distance relationship between the second front bulkhead distance, the second comfort distance, the fourth comfort distance, and the front bulkhead height; and establishing a human-machine comfort model based on the first distance relationship and the second distance relationship.

[0078] The human-machine comfort model includes a first distance relationship and a second distance relationship. The first distance relationship is the relationship between distances in a first direction, and the second distance relationship is the relationship between distances in a second direction.

[0079] Specifically, refer to Figure 3 and Figure 4 The first distance relationship is shown in formula (2).

[0080] (2)

[0081] Wherein, X4 is the first front panel distance, X5 is the first comfort distance, X6 is the third comfort distance, and X7 is the fourth front panel distance.

[0082] The second distance relationship is shown in formula (3).

[0083] (3)

[0084] Where Z3 is the second front bulkhead distance, Z4 is the second comfort distance, Z5 is the fourth comfort distance, and Z2 is the front bulkhead height.

[0085] In some embodiments, the human-computer comfort model and the forward downward field of vision model are fused to obtain a correlation model based on forward downward field of vision and human-computer comfort, including: substituting the first distance relationship and the second distance relationship into the forward downward field of vision model to obtain the correlation model.

[0086] Specifically, refer to Figure 5 Substituting the first distance relationship shown in formula (2) and the second distance relationship shown in formula (3) into the front-down field of view model shown in formula (1), we obtain the association model, which is shown in formula (4).

[0087] (4)

[0088] Wherein, X1 is the first blind spot distance, X2 is the front overhang parameter, X3 is the third front bulkhead distance, X5 is the first comfort distance, X6 is the third comfort distance, X7 is the fourth front bulkhead distance, Z1 is the side floor height, Z2 is the front bulkhead height, Z4 is the second comfort distance, and Z5 is the fourth comfort distance.

[0089] In the above embodiments, a first distance relationship is established by the distance in the first direction, and a second distance relationship is established by the distance in the second direction. The parameters affecting driving comfort are associated by the first distance relationship and the second distance relationship, so that the process of determining the parameters of the cab fully considers the comfort-related parameters and improves the driving comfort corresponding to the determined cab parameters.

[0090] In some embodiments, establishing an equilibrium model based on the preset parameter values ​​carried in the request using an association model and parameter determination includes: obtaining preset front overhang parameter values, preset third front bulkhead distance values, preset fourth front bulkhead distance values, preset first comfort distance values, preset second comfort distance values, preset third comfort distance values, and preset fourth comfort distance values ​​carried in the request using the association model, preset front overhang parameter values, preset third front bulkhead distance values, preset fourth front bulkhead distance values, preset first comfort distance values, preset second comfort distance values, preset third comfort distance values, and preset fourth comfort distance values, and determining the equilibrium model using the preset front overhang parameter values, preset third front bulkhead distance values, preset fourth front bulkhead distance values, preset first comfort distance values, preset second comfort distance values, preset third comfort distance values, and preset fourth comfort distance values.

[0091] The associated model is shown in formula (4). The front overhang parameter X2 in the associated model is set as the preset front overhang parameter value, the third front panel distance X3 is set as the preset third front panel distance value, the fourth front panel distance X7 is set as the preset fourth front panel distance value, the first comfort distance X5 is set as the preset first comfort distance value, the second comfort distance Z4 is set as the preset second comfort distance value, the third comfort distance X6 is set as the preset third comfort distance value, and the fourth comfort distance Z5 is set as the preset fourth comfort distance value.

[0092] For example, the preset front overhang parameter value is 1530, the preset third front panel distance value is 1210, the preset fourth front panel distance value is 300, the preset first comfort distance value is 700, the preset second comfort distance value is 400, the preset third comfort distance value is 1, and the preset fourth comfort distance value is 645; substituting the above preset parameter values ​​into formula (4), the equilibrium model is obtained as shown in formula (5).

[0093] (5)

[0094] Where Z1 is the side floor height, X1 is the first blind spot distance, and Z2 is the front bulkhead height.

[0095] As can be seen, the equilibrium model is used to reflect the relationship between the side floor height and the front bulkhead height.

[0096] In the above embodiments, the preset parameter values ​​are substituted into the correlation model to obtain an equilibrium model that reflects the relationship between the side floor height and the front bulkhead height. The target front bulkhead height value or the target side floor height value can be determined through the equilibrium model, so that the target front bulkhead height value or the target side floor height value is determined under the comprehensive consideration of forward downward vision and driving comfort, thereby improving the accuracy of vehicle cab parameter determination.

[0097] In some embodiments, the parameter values ​​to be processed carried in the parameter determination request are processed based on an equilibrium model to obtain target parameter values, including: when the parameter values ​​to be processed include the distance value of the first blind zone to be processed and the height value of the side floor to be processed, the distance value of the first blind zone to be processed and the height value of the side floor to be processed are processed based on an equilibrium model to obtain target front panel height value; when the parameter values ​​to be processed include the height value of the front panel to be processed and the distance value of the first blind zone to be processed, the height value of the front panel to be processed and the distance value of the first blind zone to be processed are processed based on an equilibrium model to obtain target side floor height value.

[0098] Specifically, the distance value of the first blind zone to be processed is a preset value of the first blind zone distance, and the height value of the side floor to be processed is a preset value of the side floor height.

[0099] For example, when the distance value X1 of the first blind zone to be processed is 5000 and the height value Z1 of the side floor to be processed is 1600, the target front panel height value Z2 can be calculated as 492 by formula (5).

[0100] The height value of the edge floor to be processed is a preset value.

[0101] For example, when the distance value X1 of the first blind zone to be processed is 5000 and the height value Z2 of the side floor to be processed is 550, the target front panel height value Z1 can be calculated as 1325 by formula (5).

[0102] In the above embodiments, when the height value of the side floor to be processed or the height value of the front bulkhead to be processed are obtained, the height value of the target front bulkhead or the height value of the target side floor are determined according to the equilibrium model. This ensures that the height value of the target front bulkhead or the height value of the target side floor are determined by comprehensively considering the forward downward field of vision and driving comfort. In other words, the determined vehicle cab parameters can obtain a larger forward downward field of vision while ensuring driving comfort, thereby improving the accuracy of the determination of the vehicle cab parameters.

[0103] In some embodiments, such as Figure 6 As shown, the method for determining the parameters of the vehicle cab includes:

[0104] Step 601: Determine the second blind spot distance of the cab in the first direction based on the first blind spot distance of the cab in the first direction, the front overhang parameters, the distance of the first front bulkhead and the distance of the third front bulkhead.

[0105] Step 602: Determine the third blind spot distance in the first direction based on the side floor height, front bulkhead height, and distance to the first front bulkhead;

[0106] Step 603: Based on the distances to the second and third blind zones, construct a forward lower field of vision model that determines the tangent value of the forward lower field of vision blind zone angle;

[0107] Step 604: Establish a first distance relationship between the first front panel distance, the first comfort distance, the fourth front panel distance, and the third comfort distance;

[0108] Step 605: Establish a second distance relationship between the second front panel distance, the second comfort distance, the fourth comfort distance, and the front panel height;

[0109] Step 606: Establish a human-machine comfort model based on the first distance relationship and the second distance relationship;

[0110] Step 607: Fuse the human-machine comfort model with the forward lower field of vision model to obtain the correlation model between forward lower field of vision and human-machine comfort.

[0111] Step 608: Obtain the preset front overhang parameter value, preset third front bulkhead distance value, preset fourth front bulkhead distance value, preset first comfort distance value, preset second comfort distance value, preset third comfort distance value and preset fourth comfort distance value carried in the parameter determination request;

[0112] Step 609: Determine the equilibrium model by using the associated model, preset front overhang parameter values, preset third front bulkhead distance values, preset fourth front bulkhead distance values, preset first comfort distance values, preset second comfort distance values, preset third comfort distance values, and preset fourth comfort distance values;

[0113] Step 610A: When the parameter values ​​to be processed include the distance value of the first blind zone to be processed and the height value of the side floor to be processed, the distance value of the first blind zone to be processed and the height value of the side floor to be processed are processed based on the equilibrium model to obtain the target front panel height value.

[0114] Step 610B: When the parameter values ​​to be processed include the height value of the front panel to be processed and the distance value of the first blind zone to be processed, the height value of the front panel to be processed and the distance value of the first blind zone to be processed are processed based on the equilibrium model to obtain the target side floor height value.

[0115] In the aforementioned method for determining the parameters of the vehicle cab, a forward lower field of vision model is established based on the first blind spot distance, side floor height, first front bulkhead parameters, and front overhang parameters in the first direction. A human-machine comfort model is established based on driving comfort parameters and second front bulkhead parameters. The human-machine comfort model is then fused with the forward lower field of vision model to obtain a correlation model between forward lower field of vision and human-machine comfort. In response to a parameter determination request, an equilibrium model is established based on the correlation model and the preset front bulkhead parameter values ​​and preset driving comfort parameter values ​​carried in the parameter determination request. The equilibrium model reflects the relationship between the side floor height and the front bulkhead height. The parameter values ​​to be processed carried in the parameter determination request are processed based on the equilibrium model to obtain target parameter values. The parameter values ​​to be processed include the side floor height value to be processed. The target parameter value is either the height of the front bulkhead or the height of the side floor. The driver's cab's forward downward visibility and driving comfort are combined to establish a correlation model between forward downward visibility and human-machine comfort. Based on this correlation model, preset front bulkhead parameter values, and preset driving comfort parameter values, a balance model is determined. Then, given the height of the side floor or the height of the front bulkhead to be processed, the target front bulkhead or the target side floor height is determined according to the balance model. This ensures that the target front bulkhead or the target side floor height is determined while comprehensively considering forward downward visibility and driving comfort. In other words, the determined vehicle cab parameters can achieve a larger forward downward visibility range while ensuring driving comfort, thus improving the accuracy of vehicle cab parameter determination.
