Further advantages and effects of the present invention will become readily apparent to those skilled in the art from the disclosure herein, by referring to the accompanying drawings and the preferred embodiments. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention. It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.
The connection method of the automobile wire harness in the embodiment of the invention can be executed by a server. The following will describe a connection method of an automobile wire harness according to the present invention in detail with reference to the specific embodiment, as shown in fig. 1, and the specific steps are as follows:
step 101: a preliminary segmentation scheme of the automotive wiring harness is determined.
In the preliminary segmentation scheme, the automobile wire harness is divided into a plurality of segments.
In order to make the whole vehicle circuit regular, convenient to install and protect the insulation of the wire harness, the whole vehicle circuit on the automobile is generally wound and wrapped into a bundle by insulating materials such as cotton yarn or polyvinyl chloride plastic strips of different specifications in the same area except for high-voltage wires, storage battery cables and starter cables, and is called an automobile wire harness.
The automobile wire harness can be divided into a plurality of segments, and the basis of the segments mainly considers reasonable assembly manufacturability and the minimum number of harness connectors.
For example, in the embodiment of the present invention, an automobile wire harness is divided into 11 wire harness segments, fig. 2 is a schematic diagram of a whole automobile wire harness segment, and as can be seen from fig. 2, the 11 wire harness segments include a cabin wire harness a, an instrument wire harness C, a chassis wire harness D, a front bumper wire harness F1, a rear bumper wire harness K1, a front-drive wire harness G1, a rear-drive wire harness H1, a left front-door wire harness E1, a right front-door wire harness B1, a left rear-door wire harness M1, and a right rear-door wire harness N1.
Step 102: and adjusting the first interface layout of the area controller according to the preliminary segmentation scheme to obtain a second interface layout.
The number of butt joint combinations in the second interface layout is the largest, and the butt joint combinations are one interface of the second interface layout for butt joint of the wire harness in the same section.
According to the embodiment of the invention, the regional architecture can realize efficient power and data distribution around the automobile, and meanwhile, the wiring cost is saved, and the weight and manufacturing are improved. One key component in this architecture is the regional controller, which is responsible for connecting a large number of actuators and sensors to the central computing ECU, and can play an important role in the policies within the region, depending on the application distribution. In the software level, the calculation force requirement of the whole vehicle is further concentrated, and the functional domain controller is further developed to form a vehicle-mounted calculation center; in the hardware level, in order to improve expandability, improve communication efficiency and reduce wire harness length, hardware resources such as I/O and the like are planned again, original functional boundaries are broken, area controllers are formed according to area division, and the evolution of the functional domain architecture to the whole vehicle centralized architecture is completed.
The first interface layout of the area controller is determined in advance according to the performance of parts required by the area controller and the attribute of the area controller, and comprises a plurality of interfaces, wherein each interface is used for butting a wire harness. The server adjusts the first interface layout of the area controller according to the preliminary segmentation scheme, so that the wire harnesses in the same segment are butted with the same interface of the second interface layout to the greatest extent, and the largest number of butting combinations are formed. For example, nacelle harness A interfaces one interface and instrument harness C interfaces another interface, avoiding different harnesses interfacing the same interface. And obtaining a second interface layout through adjusting the first interface layout.
Step 103: a target harness of the automotive harness that is not interfaced with the interface of the zone controller is determined.
In the embodiment of the invention, after the area controller adopts the interfaces in the second interface layout and the segmented wire harnesses for butt joint, due to the self attribute of the area controller, some target wire harnesses which cannot be in butt joint with the interfaces of the area controller remain in the wire harnesses, and the target wire harnesses can be wire harnesses in different segments or wire harnesses in the same segment.
Reasons for the remaining target harness include: the pin count of the connector in the area controller is limited or the wire harness in the circuit board cannot form a loop, and when the area controller is in butt joint with the cabin wire harness, the pin count of the connector is insufficient; the camera of the outer rearview mirror is set not to be connected with the regional controller, and a hub is required to be additionally designed to fix a butt joint wire harness;
step 104: the target wire harness in the different segments is connected by a harness connector.
In the embodiment of the invention, the server connects the target wire harnesses in different segments through the wire harness connector.
According to the invention, the first interface layout of the area controller is adjusted according to the preliminary segmentation scheme of the automobile wire harness, so that the wire harnesses in the same segment are butted with one interface of the second interface layout to the greatest extent, the number of target wire harnesses which do not belong to the same segment wire harness can be reduced, the number of wire harness connectors is reduced, meanwhile, the wire harnesses are butted with the interfaces of the area controller, the placement position of the area controller can reduce the length of the automobile wire harnesses, and the invention reduces the cost of connecting the automobile wire harnesses by reducing the number of wire harness connectors and the length of the automobile wire harnesses.
As an alternative embodiment, determining a preliminary segmentation scheme for an automotive wire harness includes: determining a preset wire harness placing position and a controller setting position of an area controller in an automobile; according to the wiring harness placement position and the controller setting position, the automobile wiring harness is segmented, and a preliminary segmentation scheme of the automobile wiring harness is obtained.
The position of the Zone controller in the automobile is a controller setting position, as shown in fig. 2, and includes three Zone controllers, namely, zone controller Zone1 (first Zone controller), zone controller Zone2 (second Zone controller) and Zone controller Zone3 (third Zone controller), zone1 and Zone2 are respectively arranged at left and right a pillars of the automobile, and Zone3 is arranged at the rear half position of the automobile body. The setting position of the controller can be determined according to actual conditions.
The first interface layout of the regional controller is preset before development of the automobile project, and specifically, the determining mode of the first interface layout is as follows: before the development of the automobile project, the server acquires interface information, electrical parameters and functional information of parts required by the area controller, then determines an electrical schematic diagram and an electrical element model selection in a PCB (Printed Circuit Board) board of the area controller according to the interface information, the electrical parameters and the functional information, and finally forms a primary ICD (Interface Control Document interface control file) according to the electrical schematic diagram and the electrical element model selection, thereby determining a first interface layout of the area controller.
The interface information of the component refers to the interface type, interface parameters and the like of the component. The electrical parameters refer to parameters determined by the performance of the component, such as resistance, current, voltage, etc. The function information refers to the functions of the components.
The wire harness placement position means that each wire harness should have a specific placement position, for example, the cabin wire harness a is placed in the a area, and the meter wire harness C is placed in the C area.
The server segments the automobile wire harness according to the wire harness placement position and the controller setting position to obtain a preliminary segmentation scheme of the automobile wire harness, so that the obtained preliminary segmentation scheme can enable the wire harness to be placed at a corresponding position, enables the wire harness to be butted with an interface of the regional controller according to the controller setting position as much as possible, and reduces the number of wire harness connectors.
As an alternative embodiment, adjusting the first interface layout of the zone controller according to the preliminary segmentation scheme includes: and adjusting the number of interfaces, the positions of the interfaces and the number of pins of the interface connector in the area controller according to the segmented wire harness.
The area controller comprises a plurality of interfaces, each interface is provided with a connector used for being in butt joint with an external wire harness, and then the server can adjust the number of the interfaces, the positions of the interfaces and the pin number of the connectors according to the number and the type of the segmented wire harnesses, so that the wire harnesses in the same segment are in butt joint with the area controller as much as possible, and the wire harnesses in the same segment are in butt joint with one interface of the second interface layout to the greatest extent.
As an alternative embodiment, after the target wire harness in the different segments is connected by the wire harness connector, the method further includes: according to interface information of the whole vehicle electric device, adjusting a wire connection scheme, wherein the wire connection scheme is a scheme for connecting target wire harnesses in different sections by adopting a wire harness connector; according to the adjusted wire connection scheme, adjusting the second interface layout of the area controller; and adopting an interface in the adjusted second interface layout to be in butt joint with the automobile wire harness outside the adjusted wire connection scheme.
In the invention, the whole vehicle electric device can be changed in the development process of the automobile project, and the server determines the interface information of the whole vehicle electric device. Some originally can't directly dock the pencil with regional controller, after interface information changes, can directly dock with regional controller's interface, then need adjust the line connection scheme, reduce the length of car pencil.
The area controller and the harness connector are used for connecting all harnesses in the automobile harness, and after the wire connection scheme is adjusted, the second interface layout of the area controller is also adjusted adaptively. At this time, the interfaces in the adjusted second interface layout are adopted to be in butt joint with the automobile wire harness outside the adjusted wire connection scheme.
According to the invention, as the development process of the automobile project, the wire connection scheme is adjusted based on the interface information of the whole automobile electric device, so that the second interface layout of the area controller is adjusted.
As an optional implementation manner, according to interface information of the whole vehicle electric device, the adjusting the wire connection scheme includes: in the development process of the automobile project, interface information of the whole automobile electric device is determined; determining a wire harness for butting the electric devices according to the interface information; if the first wire harness and the second wire harness are connected in a non-regional controller mode according to the interface information, the second wire harness is connected with the third wire harness through a wire harness connector, wherein the second wire harness is in butt joint with an interface of the first regional controller, and the third wire harness is in butt joint with an interface of the second controller; and adjusting interface butt joint of the first wire harness and the first area controller, wherein information intercommunication is carried out among the different area controllers.
According to the invention, as the development process of the automobile project is continuously advanced, the automobile electric device is also regulated, so that the interface information of the electric device can be changed adaptively, and the wiring harness for the interface butt joint of the changed electric device is determined.
Illustratively, as shown in fig. 2, the original interface information is: the wire harness A3 and the wire harness A1 are cabin wire harnesses, the wire harness A1 is connected with the wire harness D3 through a wire harness connector, no wire harness D1 is arranged at the moment, the wire harness A1 is in butt joint with an interface of the Zone controller Zone1, the wire harness D3 is in butt joint with an interface of the Zone controller Zone3, and then the wire harness connector is used, and the wire harness length A1-D3 is needed.
If the wiring harness D1 is added in the project development process, the interface of the wiring harness D1 and the Zone controller Zone1 is in butt joint, and the interface can be adjusted to be: the wire harness A3 is connected with the wire harness A1, and the wire harness A3 is connected with the Zone controller Zone3 substantially because the Zone controller Zone1 and the Zone controller Zone3 are communicated through the wire harness D1 and the wire harness D3 so as to carry out information intercommunication, and the interfaces of the wire harness A1 and the Zone1 are in butt joint.
Through this adjustment, the connection of the wire harness A1 and the wire harness D3 is omitted, the wire harness length is saved, and the wire harness connector between the wire harness A1 and the wire harness D3 is also omitted. In the development process of the automobile project, the invention can save the length of the wire harness and reduce the number of the wire harness connectors and the cost by adjusting the wire harness connection scheme.
As an alternative embodiment, adjusting the second interface layout of the zone controller according to the adjusted wire connection scheme includes: determining a remaining wire harness not included in the adjusted wire connection scheme based on the adjusted wire connection scheme; and adjusting the second interface layout of the area controller according to the residual wire harnesses, wherein the number of butt joint combinations formed by the residual wire harnesses and the adjusted second interface layout is the largest.
After the wire connection scheme is adjusted, the wire harnesses except the wire harness connector is used as the residual wire harnesses, and the residual wire harnesses are changed relative to the original segmented wire harnesses, so that the second interface layout of the area controller is correspondingly adjusted, the wire harnesses in the same segment in the residual wire harnesses are butted with one interface of the adjusted second interface layout to the greatest extent, and the number of butted combinations is the greatest.
Illustratively, the present invention provides a method of connecting a zone controller to a wiring harness, as shown in fig. 2.
In this embodiment, three area controllers are used as cores, where Zone1 and Zone2 are respectively disposed on the left and right a columns, so as to respectively implement the power distribution and control functions of the electrical components or the secondary controllers (the next-stage controllers of the area controllers) in the left and right areas.
The Zone controller Zone1 and the Zone controller Zone2 are respectively arranged at the left column and the right column of the automobile, and the Zone controller also has the function of a hub, so that information interaction and processing of a cabin area, a door area, a chassis area and an instrument area are realized through the Zone1 and the Zone2 at the left column and the right column A.

In particular, zone3 is mainly responsible for the power distribution and control functions of electrical components or secondary controllers in the rear half area of the vehicle body, so as to reduce the length of the wire harness and the like.
