[0037] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0038] See also Figure 1 , which is a flow chart of a method for determining the size of a vehicle structure provided in an embodiment of the present application, which may specifically include:

[0039] S110, constructing a steering arrangement trapezoidal mechanism of the vehicle according to the steering trapezoidal mechanism of the vehicle;

[0040] Specifically, the vehicle's steering trapezoidal mechanism includes: left and right trapezoidal arms and a steering lateral tie rod. The function of the steering trapezoidal mechanism is to concentrate the instantaneous steering center of all vehicles on one point when the vehicle is turning, so as to ensure that the four wheels are respectively rolling without slipping on circles of different radii with the point as the center. It can be understood that the steering of the vehicle mainly depends on the two front wheels, and the steering trapezoidal mechanism is located at the front wheel position of the vehicle and close to the center position of the width of the vehicle. Therefore, the vehicle steering arrangement trapezoidal mechanism constructed with the steering trapezoidal mechanism is also located at the front wheel position of the vehicle and close to the center position of the width of the vehicle.

[0041] S120. Determine the length, width and height of the vehicle according to the position and size of the steering trapezoidal mechanism.

[0042] Specifically, the length of the vehicle is determined by the position of the steering trapezoidal mechanism diverging to both sides of the vehicle's length direction, the width of the vehicle is determined by the position of the steering trapezoidal mechanism diverging to both sides of the vehicle's width direction, and the height of the vehicle is determined by the position of the steering trapezoidal mechanism diverging to both sides of the vehicle's height direction.

[0043] In summary, this method decomposes the target size of the product definition, specifically by dispersing the steering layout trapezoidal mechanism to the part sizes in various directions. When developing a new architecture, the part sizes in specific directions can be clearly changed according to design requirements to meet the product definition goals, reducing the number of iterations in the architecture development process, which is conducive to improving development collaboration efficiency, reducing R&D costs, and shortening the development cycle.

[0044] In some examples, the steps of constructing a vehicle's steering arrangement ladder mechanism include:

[0045] The position and size of the steering trapezoidal mechanism, powertrain, tires and suspension mechanism of the vehicle are determined according to the design requirements of the vehicle, wherein the design requirements of the vehicle include: operating stability, steering performance, suspension comfort, braking performance, chassis performance and power performance; the steering arrangement trapezoidal mechanism is constructed according to the position and size of the steering trapezoidal mechanism, powertrain, tires and suspension mechanism.

[0046] Specifically, the vehicle's steering layout trapezoidal mechanism is determined according to the vehicle's design requirements. The steering layout trapezoidal mechanism is constructed by the position and size of the steering trapezoidal mechanism, powertrain, tires and suspension mechanism, where the powertrain is composed of the engine and transmission and related parts. The vehicle's design requirements include: operational stability, steering performance, suspension comfort, braking performance, chassis performance and power performance. It can be understood that the position of the tire is determined by the size of the load, and the range of variation is from the tire position of the empty load to the tire position of the full load. Taking into account the impact of most design elements on the vehicle architecture size, when the performance needs to be adjusted, only the position and size of the corresponding parts need to be adjusted to adjust the position and size of the steering trapezoidal mechanism, and further adjust the length, width and height of the vehicle architecture. Thus, the product definition target size is decomposed into specific part sizes, reducing the number of iterations in the architecture development process, which is conducive to improving the development collaboration efficiency.

[0047] In some examples, the step of determining the length of the vehicle based on the position and size of the steering arrangement trapezoidal mechanism includes:

[0048] The front overhang dimension, wheelbase dimension and rear overhang dimension are determined respectively according to the design requirements of the above-mentioned vehicle length and the position and dimension of the above-mentioned steering arrangement trapezoidal mechanism, wherein the design requirements of the above-mentioned vehicle length include: safety requirements, thermal management requirements, and pedestrian protection requirements; the length dimension of the above-mentioned vehicle is determined according to the above-mentioned front drive dimension, the above-mentioned wheelbase dimension and the above-mentioned rear drive dimension.

[0049] It can be understood that the length dimension of the vehicle can be decomposed into the front overhang dimension, wheelbase dimension and rear overhang dimension of the vehicle. The front overhang dimension is the distance from the front bumper of the vehicle to the steering layout trapezoidal mechanism. Specifically, the front overhang dimension is the sum of the distance from the front bumper to the front anti-collision beam, the distance between the front anti-collision beam and the radiator, and the distance between the radiator and the steering layout trapezoidal mechanism. Among them, the positions of the front bumper, front anti-collision beam and radiator are determined by the design requirements of the vehicle length, and the design requirements of the vehicle length take into account the safety requirements, thermal management requirements, and pedestrian protection requirements.

[0050] The wheelbase dimension is the distance from the center of the vehicle's front axle to the center of the rear axle.

[0051] The rear overhang dimension is the distance from the center of the vehicle's rear axle to the rear bumper. Specifically, the rear overhang dimension is the sum of the distance from the center of the rear axle to the rear anti-collision beam and the distance from the rear anti-collision beam to the rear bumper. The positions of the rear anti-collision beam and the rear bumper are determined by the design requirements of the vehicle length. The design requirements of the vehicle length take into account the space requirements of the rear drive assembly and the rear collision passive safety requirements.

[0052] The design elements of most vehicle lengths and the position and size of the steering layout trapezoidal mechanism are taken into consideration to determine the length of the vehicle body, determine the position and size of the parts that affect the length of the vehicle body, and decompose the product definition target length size into the position and size of specific parts, which makes it easier to meet the product definition goals and reduces the number of iterations in the architecture development process, which is conducive to improving development collaboration efficiency, reducing R&D costs, and shortening the development cycle.

[0053] In some examples, the step of determining the wheelbase size based on the design requirements of the vehicle length and the position and size of the steering arrangement trapezoidal mechanism includes: determining a first size based on the front and rear collision safety requirements of the power battery of the vehicle and the space requirements occupied by the power battery capacity; determining a second size based on the space requirements for human driving and human getting on and off the vehicle; and selecting the maximum value of the first size and the second size as the wheelbase size.

[0054] It is understandable that when determining the wheelbase size of the vehicle, since the power battery needs to be placed in the middle section of the vehicle body and it is the driving and riding space of the vehicle, it is necessary to consider the impact of the above two factors on the wheelbase size. Specifically, the first size is determined based on the front and rear collision safety requirements of the power battery and the space occupied by the power battery, and the second size is determined based on the driving and riding space for the human body and the needs of getting on and off the vehicle. By comparing the first size and the second size, the maximum value is selected as the wheelbase size of the vehicle, so that the wheelbase size of the vehicle can more easily meet the product definition goals and avoid the situation where the vehicle length is insufficient.

[0055] It can be understood that the second dimension is the sum of the distance from the front axle to the front panel, the distance from the front panel to the pedal, the distance from the pedal to the front row of people, the distance from the front row of people to the rear row of people, and the distance from the rear row of people to the rear axle, where the pedal includes the brake pedal and the rest pedal.

[0056] In some examples, the step of determining the width dimension of the vehicle based on the position and size of the steering arrangement trapezoidal mechanism includes: determining the width dimension of the wheel based on the size of the powertrain and the distance between the powertrain and the fenders on both sides of the vehicle.

[0057] It is understandable that the width dimension of the vehicle is the distance between the fenders on both sides of the vehicle, in other words, it refers to the distance between the wheel arches on both sides of the vehicle. Specifically, the width dimension can be decomposed into the distance from the left fender to the left wheel, the distance from the left wheel to the left longitudinal beam, the distance from the left longitudinal beam to the powertrain, the size of the powertrain, the distance from the powertrain to the right longitudinal beam, the distance from the right longitudinal beam to the right wheel, and the distance from the right vehicle to the right fender. Among them, the size of the powertrain is determined according to the performance of the vehicle, which affects the width dimension of the vehicle. Decomposing the product definition target width dimension into the location and size of specific parts makes it easier to meet the product definition goals, reduces the number of iterations in the architecture development process, and is conducive to improving development collaboration efficiency, reducing R&D costs, and shortening the development cycle.

[0058] In some examples, the step of determining the height dimension of the vehicle according to the position and size of the steering arrangement trapezoidal mechanism includes: determining the static radius of the tire and the longitudinal distance from the wheel center of the tire to the front shock absorber fixing point according to the design requirements of the vehicle height and the position and size of the steering arrangement trapezoidal mechanism, wherein the design requirements of the vehicle height include: the tire characteristics and the suspension comfort; determining the height dimension of the vehicle according to the static radius of the tire and the longitudinal distance from the wheel center of the tire to the front shock absorber fixing point.

[0059] It can be understood that the height dimension of the vehicle is the longitudinal distance from the lowest end of the tire to the roof in a static state. Specifically, the height dimension can be decomposed into the radius dimension of the tire in a static state, the longitudinal distance from the wheel center of the tire to the front shock absorber fixing point, the longitudinal distance from the front shock absorber fixing point to the Cowl point, the orthographic projection length of the H61 dimension on the vertical plane, and the sum of the longitudinal distance from the highest point of the effective head space to the roof minus the longitudinal distance from the Cowl point to the H point. Among them, the Cowl point is the longitudinal projection point of the highest point of the rear end of the engine cover on the windshield, the H point is the position of the midpoint of the hip joint of the driver in the vehicle after the driver is seated, and the H61 dimension is the effective head space dimension.

[0060] Among them, the selection of tire size is affected by the design requirements such as vehicle shape and load size; the selection of the longitudinal distance from the wheel center of the tire to the front shock absorber fixing point is affected by the suspension position and size in the steering layout trapezoidal mechanism and the design requirements of vehicle comfort; the selection of the longitudinal distance from the front shock absorber fixing point to the Cowl point is affected by the pedestrian protection requirements; the selection of the longitudinal distance from the Cowl point to the H point is affected by the driver's downward field of vision requirements; the selection of the orthographic projection length of the H61 size on the vertical plane is affected by the head space requirements of the driver and passengers.

[0061] The height dimensions of the vehicle body are determined by taking into account the design elements of most vehicle heights and the position and size of the steering layout trapezoidal mechanism, in order to determine the position and size of the parts that affect the height of the vehicle body. The product definition target height dimensions are decomposed into the position and size of specific parts, which makes it easier to meet the product definition goals and reduces the number of iterations in the architecture development process, which is conducive to improving development collaboration efficiency, reducing R&D costs, and shortening the development cycle.

[0062] In some examples, the above vehicle architecture size determination method further includes:

[0063] Determine the length dimension range, width dimension range and height dimension range of the vehicle according to the length, width and height dimensions of the vehicle respectively; select the target length, target width and target height of the vehicle within the length dimension range, the width dimension range and the height dimension range according to the product definition target requirements of the vehicle.

[0064] Specifically, by considering the design requirements of the vehicle and the position and size of the steering layout trapezoidal mechanism, the length dimension range, width dimension range and height dimension space of the vehicle can be determined, and the vehicle target length, target width and target height that meet the product definition target are selected from the above length dimension range, width dimension range and height dimension space according to the product definition target requirements of the vehicle. The architecture size that meets the product definition target can be quickly obtained, which reduces the number of iterations in the development process, improves the development collaboration efficiency, and shortens the development cycle.
