[0047] The embodiment of the present invention solves the technical problem of low efficiency in generating the dynamics simulation model file of the whole vehicle in the prior art by providing a method and a device for generating the dynamics simulation model file of the whole vehicle.

[0048] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] This embodiment is described by taking the multi-body dynamics simulation software as Adams software as an example, but is not limited to Adams software. Adams software provides a whole vehicle dynamics simulation modeling template and a dynamics simulation modeling template for each subsystem. The dynamics simulation modeling template for each subsystem is required to establish a whole vehicle dynamics simulation model. The existing modeling method is to manually maintain each parameter in the whole vehicle dynamics simulation modeling template, including maintaining the reference path of each subsystem dynamics simulation modeling template and the parameter value of each parameter in the whole vehicle dynamics simulation modeling template. Since each parameter needs to be maintained, the efficiency of generating the whole vehicle dynamics simulation model file is low.

[0050] This embodiment finds that each time a whole vehicle dynamics simulation model file is generated, most of the parameters used for modeling in the whole vehicle dynamics simulation modeling template are fixed, and only a small number of parameters will change. Therefore, this embodiment can adopt a method of only maintaining variable parameters instead of fixed parameters when generating a whole vehicle dynamics simulation model file, thereby improving the efficiency of generating a whole vehicle dynamics simulation model file.

[0051] In the vehicle dynamics simulation modeling template, different parameters are in different rows. The premise of this embodiment is to analyze the description of all variable parameters in the template and the row where the variable parameters are located in the vehicle dynamics simulation modeling template. After analysis, this embodiment can obtain the description and row number of the variable parameters as shown in Table 1, Table 2 and Table 3. The parameters whose parameter values ​​will change during modeling include the reference path of the front suspension subsystem dynamics simulation modeling template, the reference path of the rear suspension subsystem dynamics simulation modeling template, the reference path of the steering subsystem dynamics simulation modeling template, the reference path of the front wheel subsystem dynamics simulation modeling template, the reference path of the rear wheel subsystem dynamics simulation modeling template, the reference path of the body subsystem dynamics simulation modeling template, the reference path of the powertrain subsystem dynamics simulation modeling template, the reference path of the brake subsystem dynamics simulation modeling template, the reference path of the front lateral stabilizer bar subsystem dynamics simulation modeling template, the reference path of the rear lateral stabilizer bar subsystem dynamics simulation modeling template, and the path error reference (path_error_reference nce), vertical reference (upright_reference), initial engine speed (initial_engine_rpm), throttle lag brake demand (throttle_lag_brake_demand), brake ratio (brake_ratio), front wheel maximum brake torque (front_brake_max_torque), steering gear ratio (rack_ratio), rear wheel maximum brake torque (rear_brake_max_torque), driver preview time (smart_driver_preview_time), steering gear ratio (steering_ratio) and sensor type (vx_sensor_type), etc.

[0058] After obtaining the description and row of the variable parameters in Tables 1 to 3, you can start generating the dynamics simulation model file of the whole vehicle.

[0059] In this embodiment, when the dynamics simulation model file of the whole vehicle is generated for the first time, the method for generating the dynamics simulation model file of the whole vehicle includes:

[0060] Step S1, defining a row variable corresponding to each variable parameter based on the description of the variable parameter in the vehicle dynamics simulation modeling template in the simulation software;

[0061] Step S2, assigning a value to each row variable;

[0062] Step S3, establishing a two-dimensional array consisting of a target row number and a row variable, wherein the target row number is the row number of the variable parameter in the vehicle dynamics simulation modeling template;

[0063] Step S4, write each row variable in the two-dimensional array and the row data of each fixed parameter in the vehicle dynamics simulation modeling template into a preset new file in the order of row numbers.

[0064] It can be understood that after the two-dimensional array is established for the first time, only steps S2 and S4 need to be executed when modeling again in the subsequent step, except that the subsequent step S2 needs to be changed to assign a value to the row variable corresponding to each target row number in the two-dimensional array, such as Figure 1 shown.

[0065] The variable parameters in this embodiment may include any one of a front suspension subsystem dynamics simulation modeling template reference path, a rear suspension subsystem dynamics simulation modeling template reference path, a steering subsystem dynamics simulation modeling template reference path, a front wheel subsystem dynamics simulation modeling template reference path, a rear wheel subsystem dynamics simulation modeling template reference path, a body subsystem dynamics simulation modeling template reference path, a powertrain subsystem dynamics simulation modeling template reference path, a braking subsystem dynamics simulation modeling template reference path, a front lateral stabilizer bar subsystem dynamics simulation modeling template reference path, a rear lateral stabilizer bar subsystem dynamics simulation modeling template reference path, a path error reference, a vertical reference, an initial value of the engine speed, a throttle lag braking demand, a braking ratio, a front wheel maximum braking torque, a steering gear ratio, a rear wheel maximum braking torque, a driver's preview time, a steering gear ratio, and a sensor type. or multiple, the following uses the variable parameters including the reference path of the front suspension subsystem dynamics simulation modeling template, the reference path of the rear suspension subsystem dynamics simulation modeling template, the reference path of the steering subsystem dynamics simulation modeling template, the reference path of the front wheel subsystem dynamics simulation modeling template, the reference path of the rear wheel subsystem dynamics simulation modeling template, the reference path of the body subsystem dynamics simulation modeling template, the reference path of the powertrain subsystem dynamics simulation modeling template, the reference path of the braking subsystem dynamics simulation modeling template, the reference path of the front lateral stabilizer bar subsystem dynamics simulation modeling template, the reference path of the rear lateral stabilizer bar subsystem dynamics simulation modeling template, path error reference, vertical reference, initial value of engine speed, throttle lag braking demand, braking ratio, maximum braking torque of the front wheels, steering gear ratio, maximum braking torque of the rear wheels, driver preview time, steering gear ratio and sensor type as examples for explanation.

[0066] The names of the row variables corresponding to the 10 variable parameters in Table 1 defined in step S1 are Line_frontsup, Line_rearsup, Line_steering, Line_fronttire, Line_reartire, Line_body, Line_powertrain, Line_brake, Line_frontarb, and Line_reararb. Taking Line_frontsup as an example, the assignment statement of Line_frontsup in step S2 is: Line_frontsup==' / USAGE='+full_path_name+front_sus_filename, and the reference path includes full_path_name (full path) and front_sus_filename (file name).

[0067] The names of the row variables corresponding to the two variable parameters in Table 2 defined in step S1 are Line_path_error_reference and Line_upright_reference, respectively. The statements for assigning values ​​to the two row variables in step S2 are: Line_path_error_reference == 'path_error_reference' + 'single'

[0068] +x+”+y+”+z, Line_upright_reference=='upright_reference'+'left / right'+x+”+y+”+z. The description of the variable parameter path_error_reference includes the parameter name "path_error_reference", the data type "single" and the coordinate value "xyz", and the description of the variable parameter upright_reference includes the parameter name "upright_reference", the direction "left / right" and the coordinate value "xyz".

[0069] The names of the row variables corresponding to the 9 variable parameters in Table 3 defined in step S1 are Line_initial_engine_rpm, Line_throttle_lag_brake_demand, Line_brake_ratio, Line_front_brake_max_torque, Line_rack_ratio, Line_rear_brake_max_torque, Line_smart_driver_preview_time, Line_steering_ratio, and Line_vx_sensor_type, respectively. Taking Line_initial_engine_rpm as an example, the assignment statement of step S2 can be: Line_initial_engine_rpm=='initial_engine_rpm'+'single'+'real'+val. The description of the variable parameter initial_engine_rpm includes the parameter name "initial_engine_rpm", the data type "single" and the engine speed value "val".

[0070] As can be seen from Tables 1-3, the target row numbers of this embodiment include 33, 41, 49, 57, 65, 73, 81, 89, 97, 105, 113, 114, 118, 119, 121, 123, 125, 127, 129, 131, and 133. After the assignment of each row variable is completed, the two-dimensional array constructed in step S3 is:

[0071] Arr==[(33,Line_frontsup),

[0072] (41,Line_rearsup),

[0073] (49,Line_steering),

[0074] (57,Line_fronttire),

[0075] (65,Line_reartire),

[0076] (73,Line_body),

[0077] (81,Line_powertrain),

[0078] (89,Line_brake),

[0079] (97,Line_frontarb),

[0080] (105,Line_reararb)]

[0081] (113,Line_path_error_reference),

[0082] (114,Line_upright_reference),

[0083] (118,Line_initial_engine_rpm),

[0084] (119,Line_throttle_lag_brake_demand),

[0085] (121,Line_brake_ratio),

[0086] (123,Line_front_brake_max_torque),

[0087] (125,Line_rack_ratio),

[0088] (127,Line_rear_brake_max_torque),

[0089] (129,Line_smart_driver_preview_time),

[0090] (131,Line_steering_ratio),

[0091] (133,Line_vx_sensor_type)]

[0092] Step S4 may include: starting from the current row number being the first preset value, looping through the preset process until the current row number is the second preset value; the preset process includes: obtaining the current row number; if the current row number is the target row number, writing the row variable corresponding to the current row number in the two-dimensional array into a new file; if the current row number is not the target row number, writing the row data corresponding to the current row number in the vehicle dynamics simulation modeling template into a new file; adding one to the current row number. All parameters except the variable parameters in the vehicle dynamics simulation modeling template are fixed parameters.

[0093] The vehicle dynamics simulation modeling template of this embodiment has a total of 139 rows, so the first preset value can be 1 and the second preset value can be 139. The principle of step S4 is as follows Figure 2 As shown, Figure 2The second element in the array Arr[] should all be row variables. The number "1" in the figure simply replaces the English name of the row variable. First, the current row number is 1, and row number 1 is not the target row number, so the row data of the first row in the vehicle dynamics simulation modeling template is written into the new file file_carmdl. In this embodiment, writing the row data corresponding to the current row number in the vehicle dynamics simulation modeling template into the new file can include: storing the vehicle dynamics simulation modeling template as a behavior string into the Numpy list class variable val_list, the statement expression is file_cartpl = open (full_path + car_filenametpl) (file_cartpl is the name of the vehicle dynamics simulation modeling template, full_path + car_filenametpl are the full path + file name opened respectively), val_list = file_cartpl.readlines(); write the row data corresponding to the current row number in the list class variable val_list into the new file file_carmdl. For the first row, the first row of data in val_list is written to the first row of the new file file_carmdl. Then add one to the current row number. The current row number is 2. Row number 2 is also not the target row number. Write the second row of data in val_list to the second row of the new file file_carmdl. Row numbers 3 to 32 are not the target row numbers. Write the third to third rows of data in val_list in sequence to the third to third rows of the new file file_carmdl. Row number 33 is the target row number. Write the row variable Line_frontsup corresponding to row number 33 in the two-dimensional array Arr[] to the 33rd row of the new file file_carmdl. And so on, until the 139th row of data in val_list is written to the 139th row of the new file file_carmdl. The resulting new file file_carmdl.asy is the required vehicle dynamics simulation model file. Open the file_carmdl.asy file in the Adams software, and you can get the following: Figure 3 The vehicle dynamics simulation model is shown.

[0094] As can be seen from the above, this embodiment assigns a value to the row variable corresponding to each target row number in the two-dimensional array, so as to realize the maintenance of variable parameters, and writes each row variable in the two-dimensional array and the row data of each fixed parameter in the vehicle dynamics simulation modeling template into a preset new file in the order of row numbers. The obtained new file is the required vehicle dynamics simulation model file. In the process of generating the vehicle dynamics simulation model file, only a small number of variable parameters need to be maintained, thereby improving the efficiency of generating the vehicle dynamics simulation model file.

[0095] like Figure 4As shown, this embodiment also provides a device for generating a dynamics simulation model file of a whole vehicle, comprising:

[0096] An assignment module is used to assign a value to a row variable corresponding to each target row number in a preset two-dimensional array;

[0097] A writing module is used to write each row variable in the two-dimensional array and the row data of each fixed parameter in the vehicle dynamics simulation modeling template into a preset new file in the order of row numbers;

[0098] The two-dimensional array is composed of a target row number and a row variable. The target row number is the row number of the row where the variable parameter in the vehicle dynamics simulation modeling template is located in the vehicle dynamics simulation modeling template, and the row variable is a description of the variable parameter.

[0099] Further, the variable parameters may include a reference path of a front suspension subsystem dynamics simulation modeling template, a reference path of a rear suspension subsystem dynamics simulation modeling template, a reference path of a steering subsystem dynamics simulation modeling template, a reference path of a front wheel subsystem dynamics simulation modeling template, a reference path of a rear wheel subsystem dynamics simulation modeling template, a reference path of a body subsystem dynamics simulation modeling template, a reference path of a powertrain subsystem dynamics simulation modeling template, a reference path of a braking subsystem dynamics simulation modeling template, a reference path of a front stabilizer bar subsystem dynamics simulation modeling template, a reference path of a rear stabilizer bar subsystem dynamics simulation modeling template, a path error reference, a vertical reference, an initial value of the engine speed, a throttle lag braking demand, a braking ratio, a maximum braking torque of the front wheels, a steering gear ratio, a maximum braking torque of the rear wheels, a driver's preview time, a steering gear ratio, and a sensor type.

[0100] Furthermore, the whole vehicle dynamics simulation model file generating device may also include:

[0101] A definition module is used to define each row variable based on the vehicle dynamics simulation modeling template;

[0102] The array module is used to create a two-dimensional array consisting of target row numbers and row variables.

[0103] Furthermore, the write module can also be used to:

[0104] Starting from the current line number being the first preset value, the preset process is executed cyclically until the current line number is the second preset value;

[0105] The preset process includes:

[0106] Get the current line number;

[0107] If the current line number is the target line number, write the line variable corresponding to the current line number in the two-dimensional array into the new file;

[0108] If the current line number is not the target line number, the line data corresponding to the current line number in the vehicle dynamics simulation modeling template is written into a new file;

[0109] Increase the current line number by one.

[0110] Based on the same inventive concept as the method for generating a dynamics simulation model file for a whole vehicle described above, this embodiment also provides an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the steps of any one of the methods for generating a dynamics simulation model file for a whole vehicle described above are implemented.
