Wherein the target controller 102 (target controller refers to a sensor in the target sensor) communicates with the vehicle management platform 104 through a network. The target controller 102, upon receiving the target file sent by the vehicle management platform 104, reads out values of respective standard parameters related to the target sensor from the target file; the target file is determined by the product design platform and stored in the database, and is obtained from the database by the vehicle management platform 104 according to the calibration request sent by the user side; the calibration request includes information of the target vehicle; the target controller 102 determines the position of the target sensor in the target vehicle based on the values of the respective standard parameters.

The terminal can be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things equipment and portable wearable equipment, and the internet of things equipment can be smart speakers, smart televisions, smart air conditioners, smart vehicle-mounted equipment and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The server may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.

In one embodiment, as shown in fig. 2, a method for determining a position of a sensor of a vehicle is provided, and the method is applied to the target controller 102 in fig. 1, for example, and includes the following steps:

step S202, when a target file sent by a vehicle management platform is received, reading values of standard parameters related to a target sensor from the target file; the target file is determined by the product design platform and stored in the database, and the target file is obtained from the database by the vehicle management platform according to the calibration request sent by the user side; the calibration request includes information of the target vehicle.

The vehicle management platform is a platform in the whole vehicle production stage and is used for generating and managing. The vehicle management platform is deployed in a first computer device. The target sensor is a camera, a radar, etc. of the target vehicle, and the standard parameter refers to a standardized parameter related to a component part of the vehicle, including a vehicle type and a component, the vehicle type being determined according to a structure of a cab, a front suspension, etc. of the vehicle, and the component referring to a component, such as a tire, a glass, etc. of the vehicle. Standard parameters may be considered as intrinsic parameters. The target file stores therein values of standard parameters related to the target vehicle. Each vehicle uniquely corresponds to a file. The database stores at least one file of the vehicle. The product design platform refers to a platform in a product design management stage for generating a file of a vehicle, for example, a target file for generating a target vehicle. The product design platform is deployed in the second computer equipment, and the product design management stage is positioned before the whole vehicle generation stage. The user side can be regarded as a scanning device for acquiring information of vehicles, wherein the information comprises vehicle type codes of the vehicles, and each vehicle has a unique corresponding vehicle type code. The target vehicle is a commercial vehicle, such as a truck, or the like.

Optionally, in the whole vehicle production stage, the user side responds to the scanning operation of the vehicle type code of the target vehicle, a calibration request containing the information of the target vehicle is sent to the vehicle management platform, and the vehicle management platform queries a target file corresponding to the information of the target vehicle from the database according to the calibration request and sends the target file to the target controller in the target sensor. The target controller reads out values of standard parameters related to the target sensor from the target file. Step S204, determining the position of the target sensor in the target vehicle according to the values of the standard parameters.

The position of the target sensor in the target vehicle is determined through at least one position parameter of the target sensor, and the position parameter is used for reflecting the position information of the target sensor under the whole vehicle coordinate system. Different vehicles, the corresponding sets of location parameters are different, the set of location parameters including at least one location parameter.

Optionally, the target controller determines a value of at least one position parameter of the target sensor according to the values of the respective standard parameters, and determines a position of the target sensor in the target vehicle according to the value of the at least one position parameter.

In some embodiments, reading values of standard parameters associated with the target sensor from the target file includes: acquiring at least one position parameter of a target sensor, and acquiring a mapping relation between the position parameter and a standard parameter; for each position parameter, reading the value of each standard parameter related to the position parameter from the target file according to the mapping relation and the position parameter.

Optionally, the target controller acquires at least one position parameter of a target sensor to be installed on the target vehicle, acquires a mapping relation between the position parameter and a standard parameter, determines each standard parameter related to the position parameter according to the mapping relation and the position parameter for each position parameter, and reads the value of each standard parameter from the target file.

It should be noted that, for different vehicles, the location parameter may be used as a standard parameter. For example, for a first location parameter, the first location parameter corresponds to a standard parameter 1 and a standard parameter 2, wherein the standard parameter 2 is a second location parameter. For another example, the third position parameter corresponds to the standard parameter 3, and the standard parameter 3 is the fourth position parameter. The specific examples are not limited.

In the whole vehicle production stage, the target controller determines the mapping relation between the position parameters and the standard parameters according to the pre-stored conversion function of each position parameter. The conversion function of each location parameter is a function of the location parameter as a function of the corresponding at least one standard parameter transformation.

For example, as shown in FIG. 3, a schematic diagram of a target vehicle in one embodiment is shown. Taking the target sensor as an example of a camera, in order to determine the installation position of the camera (to be installed on the windshield of the cab) on the target vehicle, at least one position parameter matched with the target vehicle is analyzed in combination with the vehicle information and the requirement of the target vehicle, as shown in fig. 3, 6 position parameters, namely the installation height of the camera (namely a in fig. 3), the distance from the camera to the outer edge of the left wheel (namely b in fig. 3), the distance from the camera to the outer edge of the right wheel (namely c in fig. 3), the distance from the camera to the XZ face of the vehicle (namely d in fig. 3), the distance from the camera to the front axle (namely e in fig. 3), and the distance from the camera to the front protection front end (namely f in fig. 3), are respectively present.

For each position parameter, at least one standard parameter corresponding to the position parameter is determined in combination with the corresponding influencing factors. The staff member may analyze the influence factors to determine at least one standard parameter corresponding to the location parameter, or may acquire historical analysis data and query the historical analysis data for at least one standard parameter corresponding to the location parameter. The historical analysis data includes a mapping relationship of historical location parameters and historical standard parameters. The specific examples are not limited.

For example, for a camera mounting height (i.e., a in fig. 3), the corresponding influencing factors are: the height of the cab, the arrangement positions of the tire and the camera in the Z-axis direction respectively; the distance from the camera to the outer edge of the left wheel (i.e. b in fig. 3), the corresponding influencing factors are: the width of the cab and the arrangement positions of the cameras in the Y-axis direction respectively; the distance from the camera to the outer edge of the right wheel (i.e. c in fig. 3), the corresponding influencing factors are: the width of the cab and the arrangement positions of the cameras in the Y-axis direction respectively; the camera-to-vehicle XZ face distance (i.e., d in fig. 3), the corresponding influencing factors are: the arrangement position of the cameras in the Y-axis direction; the distance from the camera to the front axis (i.e. e in fig. 3), the corresponding influencing factors are: cab modeling and the arrangement position of the cameras in the X-axis direction; the distance from the camera to the front of the front bumper (i.e., f in fig. 3), the corresponding influencing factors are: the cab model, the front overhang and the cameras are respectively arranged at the positions in the X-axis direction.

In this embodiment, according to the mapping relationship between the location parameters and the standard parameters, the values of the standard parameters related to each location parameter can be quickly read from the target file, so that the file reading efficiency is improved.

In the method for determining the position of the vehicle sensor, when a target file sent by the vehicle management platform is received, values of standard parameters related to the target sensor are read from the target file; the target file is determined by a product design platform and stored in a database, and the target file is acquired from the database by the vehicle management platform according to a calibration request sent by a user side; the calibration request comprises information of a target vehicle; that is, before the whole vehicle is produced, the position parameters of the sensors do not need to be determined one by one, based on the position parameters, the position of the target sensor in the target vehicle is automatically determined according to the values of the standard parameters, the position parameters of each vehicle do not need to be determined again, the position of the target sensor can be automatically converted based on the acquired target file, the occupied ratio of manual operation is reduced, the error rate is reduced, and the efficiency of position determination is improved.

In some embodiments, determining the location of the target sensor in the target vehicle based on the values of the respective standard parameters includes: for each position parameter, acquiring a conversion function of the position parameter, wherein the conversion function of the position parameter is a function of the position parameter changing along with the change of at least one corresponding standard parameter; determining the value of the position parameter according to the value of each standard parameter in the target file and the conversion function of the position parameter; the position of the target sensor in the target vehicle is determined based on the values of the respective position parameters.

Optionally, for each location parameter, the first controller reads a conversion function of the location parameter, and determines at least one standard parameter corresponding to the location parameter according to the conversion function. The first controller reads the value of at least one standard parameter corresponding to the position parameter from the target file, and determines the value of the position parameter according to the conversion function of the position parameter and the value of at least one standard parameter corresponding to the position parameter. The first controller determines a position of the target sensor in the target vehicle based on the values of the respective position parameters.

It should be noted that, for each location parameter, the conversion function of the location parameter is a function that the location parameter changes with the corresponding at least one standard parameter, and then the conversion function of the location parameter may be a function that the location parameter changes with the corresponding one standard parameter, where the corresponding one standard parameter may be the location parameter itself, other location parameters, or other parameters that are not location parameters, for example, for the location parameter: the distance (e) from the camera to the front axle corresponds to the conversion function of the distance (e) from the camera to the front axle, i.e. the distance (e) from the camera to the front axle is both a position parameter and a standard parameter for the target vehicle. Of course, the conversion function of the position parameter may also be a function of the position parameter as a function of a corresponding plurality of standard parameters.

Illustratively, as shown in fig. 3, the standard parameters corresponding to the mounting height of the camera are the Z-direction height from the camera to the center of the front axle and the tire rolling radius, and the transfer function of the mounting height of the camera is: the mounting height of the camera is equal to the sum of the Z-direction height from the camera to the wheel center of the front axle and the rolling radius of the tire;

the standard parameters corresponding to the distance from the camera to the outer edge of the left wheel are the width of the cab and the distance from the camera to the XZ surface of the vehicle, and the conversion function of the distance from the camera to the outer edge of the left wheel is as follows: the distance from the camera to the outer edge of the left wheel is equal to the difference between half of the width of the cab and the distance from the camera to the XZ surface of the vehicle;

the standard parameters corresponding to the distance from the camera to the outer edge of the right wheel are the width of the cab and the distance from the camera to the XZ surface of the vehicle, and the conversion function of the distance from the camera to the outer edge of the right wheel is as follows: the distance from the camera to the outer edge of the right wheel is equal to the sum of half of the width of the cab and the distance from the camera to the XZ surface of the vehicle;

the distance from the camera to the XZ surface of the vehicle is not only a position parameter, but also a standard parameter; the transfer function of the camera to vehicle XZ face distance is: the camera-to-vehicle XZ face distance is equal to a first constant;

the distance from the camera to the front axle is not only a position parameter, but also a standard parameter; the transfer function of the distance from the camera to the front axle is: the distance from the camera to the front axle is equal to a second constant;

The standard parameters corresponding to the distance from the camera to the forefront of the front bumper are the X-direction distance between the front overhang of the vehicle and the center of the front axle wheel, and the conversion function corresponding to the distance from the camera to the forefront of the front bumper is as follows: the distance from the camera to the forefront of the front bumper is equal to the difference between the front overhang of the vehicle and the X-direction distance from the camera to the center of the front axle.

In this example, for each location parameter, the value of the location parameter can be automatically calculated according to the value of each standard parameter in the target file and the conversion function of the location parameter; according to the values of the position parameters, the position of the target sensor in the target vehicle is rapidly and accurately determined, and the efficiency of position determination is improved.

In one embodiment, as shown in fig. 4, a method for determining a design file of a vehicle sensor is provided, and the method is applied to a second computer device (a product design platform is deployed on the second computer device) for illustration, and includes the following steps:

step S402, acquiring at least one location parameter of a target sensor to be mounted on a target vehicle, and acquiring at least one standard parameter related to each location parameter.

Optionally, the second computer device obtains the design request, and obtains at least one pre-stored position parameter of the target sensor to be installed on the target vehicle and at least one standard parameter related to each position parameter according to the information of the target vehicle carried by the design request and the information of the target vehicle.

The method comprises the steps of establishing a demand list corresponding to a target vehicle in advance aiming at the target vehicle, wherein the demand list comprises at least one position parameter in a target sensor to be installed on the target vehicle, and determining at least one standard parameter related to each position parameter according to influence factors of each position parameter. After at least one standard parameter related to each position parameter is determined, a standard parameter library corresponding to the target vehicle is established according to the plurality of standard parameters.

Step S404, for each standard parameter, determining a component corresponding to the standard parameter.

For the target vehicle, the component parts include a vehicle type including a cab, a front suspension, and the like, and the component parts include tires, glass, and the like. For each vehicle, the same vehicle model may correspond to different parts, may correspond to the same parts, and different vehicle models may correspond to different parts, may correspond to the same parts, and is not particularly limited.

Optionally, for each standard parameter, the second computer device determines the component parts associated with said standard parameter.

The standard parameter m is illustratively the Z-directional height of the camera to the center of the front axle wheel, and the component part related to the standard parameter m is the cab in the vehicle model. The standard parameter e is the X-direction distance between the camera and the center of the front axle wheel, and the component related to the standard parameter e is a cab in the vehicle type. The standard parameter d is the distance from the camera to the XZ surface of the vehicle, and the component related to the standard parameter d is a cab in the vehicle type. The standard parameter p is the width of the cab, and the component related to the standard parameter p is the cab in the vehicle type. The standard parameter q is the front overhang of the vehicle, and the component related to the standard parameter q is the cab in the vehicle type. The standard parameter r is the rolling radius of the tire, and the component part related to the standard parameter r is the tire in the part.

It should be noted that, a certain value, such as a height, a distance, a width, a radius, etc., which is characterized by the standard parameter is related to the vehicle, i.e., which component part in the vehicle is mapped to, i.e., the component part corresponding to the standard parameter is determined.

Step S406, determining a target assembled vehicle assembled with the component parts according to the target composition type and borrowing relation of the component parts; the borrowing relationship is a mapping relationship between the composition type and the assembled vehicle.

Among them, the composition type reflects the types of the constituent parts, for example, for the vehicle 1, which of the first class, …, and the x-th class the cab used by the vehicle 1 belongs to. By the borrowing relationship, it is possible to know whether the component types of the component parts in the target vehicle have been assembled into the assembled vehicle, for example, the target vehicle selects the cab 1, and it is determined that the target assembled vehicle 1 and the target vehicle both use the same cab, that is, both use the cab 1, based on the borrowing relationship. Based on the method, the multiplexing degree of the vehicle data is high, the number of parameters actually required to be measured can be reduced, the design workload of the whole vehicle is reduced, and the error rate is reduced. That is, according to the borrowing relationship, portability exists, one vehicle is not needed to measure data, the workload is reduced, and the working efficiency and the quality are improved.

Optionally, the second computer device determines whether the component parts corresponding to the standard parameters are of a target component part type, and if so, determines the target assembled vehicle assembled with the component parts according to the target component type and the borrowing relation of the component parts.

In some embodiments, the method further comprises: in the case where it is verified that the composition type of the constituent element is not the new composition type, the composition type of the constituent element is taken as the target composition type.

Alternatively, the second computer apparatus checks whether the composition type of the component part is a new composition type from among the pre-stored composition types, and in the case where it is checked that the composition type of the component part is not a new composition type, takes the composition type of the component part as a target composition type, and returns to step S406 to continue execution.

If the composition type of the component is a new composition type, it is stated that the component is unassembled, and the corresponding standard parameter is measured and not stored in the second computer device.

Based on this, in the case where it is verified that the composition type of the constituent element is the new composition type, the standard parameter is measured by the measuring apparatus, and the measured value is transmitted to the second computer apparatus by the measuring apparatus, and the step S410 is returned to continue execution.

In the present embodiment, in the case where it is verified that the composition type of the constituent element is not the new composition type, the composition type of the constituent element is taken as the target composition type. Therefore, the component parts can be ensured to be assembled and configured in the assembled vehicle, and the standard parameters corresponding to the component parts are proved to exist, so that the component parts can be directly reused without re-measurement, the workload is reduced, and the working efficiency and the quality are improved.

Step S408, determining a value of the standard parameter according to the assembly data of the target assembled vehicle.

Wherein the fitting data of the vehicle includes values of standard parameters related to the constituent parts that have been fitted to the vehicle.

Optionally, the second computer device obtains the assembly data of the target assembled vehicle and reads the value of the standard parameter from the assembly data of the target assembled vehicle.

In step S410, the values of the standard parameters are stored in a preset file, so as to obtain a target file of the target vehicle.

The preset file is a product design file, and storage areas in which standard parameters related to a target vehicle are preset, wherein each storage area corresponds to one standard parameter, and each storage area has a unique corresponding storage address.

For each standard parameter, the second computer device stores the value of the standard parameter into the corresponding storage address in the preset file according to the storage address corresponding to the standard parameter until the value of each standard parameter is stored into the preset file, and takes the preset file storing the value of each standard parameter as the target file. The second computer device stores the target file in a database. In the whole vehicle production stage, a user side responds to scanning operation of a vehicle model code of a target vehicle, a calibration request containing information of the target vehicle is sent to a vehicle management platform, and according to the calibration request, first computer equipment inquires a target file corresponding to the information of the target vehicle from a database and sends the target file to a target controller in a target sensor. The target controller reads out values of standard parameters related to the target sensor from the target file. The target controller determines the position of the target sensor in the target vehicle according to the values of the standard parameters.

After the target file of the target vehicle is obtained, the target file is stored in the database, so that the target file can be issued to a target controller in the target sensor in the subsequent whole vehicle production stage, the information transmission characteristic is realized, and the production of the vehicle is more convenient. Each target vehicle corresponds to one target file, and the corresponding target file can be accurately inquired according to the calibration request, so that the automatic position parameter value determination is rapidly carried out, the management is simpler and more convenient, and the component misloading rate is reduced.

According to the method for determining the vehicle sensor design file, at least one position parameter of the target sensor to be installed on the target vehicle is obtained, and at least one standard parameter related to each position parameter is obtained, namely, the standardized parameter corresponding to each position parameter is predetermined, so that direct one-to-one measurement of the position parameters is avoided. For each standard parameter, determining the component part to which the standard parameter corresponds, thereby determining with which component part of the target vehicle the standard parameter is related; according to the target composition type and borrowing relation of the component parts, the target assembled vehicle with the component parts can be accurately determined; the borrowing relationship is a mapping relationship between the composition type and the assembled vehicle. In this way, according to the assembly data of the target assembled vehicle, the value of the standard parameter is directly determined, namely, the value of the standard parameter is directly multiplexed, repeated determination is not needed, and invalid calculation is avoided. And storing the values of the standard parameters into preset files to directly obtain the target file of the target vehicle, so that the generation efficiency of the target file is ensured, the position of the target sensor is automatically determined according to the target file, and the position determination efficiency is improved.

In some embodiments, storing the values of the standard parameters in a preset file to obtain a target file of the target vehicle, including: determining a storage address of the standard parameter in the design file according to the target composition type, and correspondingly storing the value of the standard parameter to the storage address; and taking the preset file storing the values of the standard parameters as a target file of the target vehicle.

Optionally, for each standard parameter, the second computer device obtains an association relationship between the target composition type and the storage address, and determines the storage address of the standard parameter in the design file according to the association relationship between the target composition type and the storage address. And taking the preset file storing the values of the standard parameters as a target file of the target vehicle.

It should be noted that, the association relationship determines the respective storage addresses of different target composition types, so that data storage and data extraction can be facilitated.

In the embodiment, the storage address of the standard parameter in the design file is accurately positioned according to the target composition type, and the value of the standard parameter is correspondingly stored to the storage address, so that the storage efficiency of the data is improved. And taking the preset file storing the values of the standard parameters as a target file of the target vehicle. Therefore, the position of the target sensor can be automatically determined according to the target file, and the efficiency of position determination is improved.

In a particular embodiment, a position determination system is provided that includes a first computer device, a second computer device, and a target sensor of the target sensors. The method comprises the following specific steps:

in the product design management stage, a product design platform in the second computer device acquires at least one position parameter of a target sensor to be installed on a target vehicle, and acquires at least one standard parameter related to each position parameter. For each standard parameter, the product design platform in the second computer device checks whether the composition type of the component part is a new composition type from the prestored composition types, measures the standard parameter by the measuring device and sends the measured value to the product design platform in the second computer device by the measuring device when the composition type of the component part is checked to be the new composition type, and returns to step S410 to continue execution.
