Vehicles can adopt an architecture that includes multiple zone controllers (ZCUs), which significantly reduces the vehicle wiring harness and realizes intelligent power distribution within the zone controller. It also integrates traditional electrical fuse boxes, reducing the cost of the entire vehicle and wiring harness.

[0049] Embodiments of the present application will be described below with reference to the accompanying drawings and preferred embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the contents disclosed in the present specification. The present application can also be implemented or applied by means of other different specific embodiments, and various modifications or changes can be made to the details in the present specification based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application, and are not intended to limit the protection scope of the present application.

[0050] The connection method of the automobile wire harness in the embodiment of the application can be executed by a server. The connection method of the automobile wire harness provided by the application will be described in detail below in combination with a specific embodiment, as shown in Figure 1 The specific steps are as follows:

[0051] Step 101: determining a preliminary segmentation scheme of the automobile wire harness.

[0052] In the preliminary segmentation scheme, the automobile wire harness is divided into multiple segments.

[0053] In order to make the whole vehicle line regular, installation convenient and protect the insulation of the wire harness, the whole vehicle line on the automobile, except for the high-voltage line, the battery cable and the starter cable, is generally wrapped into a bundle by using an insulating material such as cotton yarn or a polyvinyl chloride plastic tape, which is called an automobile wire harness.

[0054] The automobile wire harness can be divided into multiple segments, and the division of the segments mainly considers the process rationality of assembly and the minimum number of wire harness connectors.

[0055] For example, in the embodiment of the application, the automobile wire harness is divided into 11 wire harness segments, Figure 2 The whole vehicle wire harness segmentation schematic diagram is shown in FIG. 1. Figure 2 As can be seen from FIG. 1, the 11 wire harness segments include the engine compartment wire harness A, the instrument wire harness C, the chassis wire harness D, the front bumper wire harness F1, the rear bumper wire harness K1, the front drive wire harness G1, the rear drive wire harness H1, the left front door wire harness E1, the right front door wire harness B1, the left rear door wire harness M1 and the right rear door wire harness N1.

[0056] Step 102: adjusting the first interface layout of the regional controller according to the preliminary segmentation scheme to obtain a second interface layout.

[0057] In the second interface layout, the number of docking combinations is the largest, and the docking combination is the wire harness in the same segment docking one interface of the second interface layout.

[0058] In the embodiment of the application, the regional architecture can realize efficient power and data distribution around the automobile, while saving wiring cost, improving weight and manufacturing. 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 strategy of distributing in the region according to the application. At the software level, the computing power requirement of the whole vehicle is further concentrated, and the function domain controller will further develop to form a vehicle computing center; at the hardware level, in order to improve scalability, improve communication efficiency and reduce the length of the wire harness, the I / O and other hardware resources will be re-planned, breaking the original function boundary, dividing according to the region, forming a regional controller, and completing the evolution of the function domain architecture to the centralized architecture of the whole vehicle.

[0059] The first interface layout of the area controller is determined in advance according to the performance of the required parts of the area controller and the attribute of the area controller, and the first interface layout includes a plurality of interfaces, each of which is used to connect 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 connected to the same interface of the second interface layout to the greatest extent to form the most number of connection combinations. For example, cabin wire harness A is connected to one interface, and instrument wire harness C is connected to another interface, avoiding different wire harnesses being connected to the same interface. The second interface layout is obtained after the adjustment of the first interface layout.

[0060] Step 103: determining target wire harnesses in the automobile wire harnesses that are not connected to the interfaces of the area controller.

[0061] In the embodiment of the application, after the area controller is connected to the interfaces in the second interface layout and the segmented wire harnesses, due to the attribute of the area controller itself, some target wire harnesses that cannot be connected to the interfaces of the area controller will be left in the wire harnesses. The target wire harnesses can be wire harnesses in different segments or wire harnesses in the same segment.

[0062] The reasons for the remaining target wire harnesses include that the number of pins of the connector in the area controller is limited or the wire harnesses in the circuit board cannot form a loop. For example, when the area controller is connected to the cabin wire harness, the number of pins of the connector is not enough; the outside rearview mirror camera is not connected to the area controller and needs to be additionally designed as a concentrator to connect the wire harnesses;

[0063] Step 104: connecting the target wire harnesses in different segments through a wire harness connector.

[0064] In the embodiment of the application, the server connects the target wire harnesses in different segments through a wire harness connector.

[0065] In the application, the first interface layout of the area controller is adjusted according to the preliminary segmentation scheme of the automobile wire harnesses, so that the wire harnesses in the same segment are connected to one interface of the second interface layout to the greatest extent. In this way, the number of target wire harnesses that do not belong to the same segment can be reduced, thereby reducing the number of wire harness connectors. At the same time, the automobile wire harnesses are connected to the interfaces of the area controller, and the placement position of the area controller can reduce the length of the automobile wire harnesses. The application reduces the cost of connecting the automobile wire harnesses by reducing the number of wire harness connectors and reducing the length of the automobile wire harnesses.

[0066] As an optional implementation, determining the preliminary segmentation scheme of the automobile wire harnesses includes: determining a preset wire harness placement position and a controller setting position of the area controller in the automobile; and segmenting the automobile wire harnesses according to the wire harness placement position and the controller setting position to obtain the preliminary segmentation scheme of the automobile wire harnesses.

[0067] The position of the zone controller in the automobile is a controller setting position, such as Figure 2 As shown, three zone controllers are included, namely, zone controller Zone1 (first zone controller), zone controller Zone2 (second zone controller) and zone controller Zone3 (third zone controller), Zone1 and Zone2 are arranged at the left and right A pillars of the automobile respectively, and Zone3 is arranged at a position in the rear half of the automobile body. The controller setting position can be determined according to actual conditions.

[0068] The first interface layout of the zone controller is pre-set before the development of the automobile project. Specifically, the determination manner of the first interface layout is as follows: before the development of the automobile project, the server obtains the interface information, electrical parameters and function information of the parts required by the zone controller, then determines the electrical schematic diagram and electrical component selection in the PCB (Printed Circuit Board) of the zone controller according to the interface information, electrical parameters and function information, and finally forms a preliminary version of ICD (Interface Control Document) according to the electrical schematic diagram and electrical component selection, so as to determine the first interface layout of the zone controller.

[0069] Among them, the interface information of the parts refers to the interface type, interface parameter and the like of the parts. The electrical parameters refer to the parameters determined according to the performance of the parts, such as resistance, current, voltage and the like. The function information refers to the function of the parts.

[0070] The wire harness placement position refers to that each section of wire harness should have a specific placement position, for example, the engine compartment wire harness A is placed in area a, and the instrument wire harness C is placed in area c.

[0071] 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. The preliminary segmentation scheme obtained in this way can make the wire harness placed in the corresponding position, and make the wire harness connected to the interface of the zone controller according to the controller setting position as much as possible, so as to reduce the number of wire harness connectors.

[0072] As an optional implementation, adjusting the first interface layout of the zone controller according to the preliminary segmentation scheme includes: adjusting the number of interfaces, the position of interfaces and the pin number of interface connectors in the zone controller according to the segmented wire harness.

[0073] The regional controller comprises a plurality of interfaces, each interface is provided with a connector, and the connector is used for docking with an external wire harness, so that the server can adjust the number of interfaces, the position of the interfaces and the number of pins of the connectors according to the number and type of the segmented wire harnesses, so that as many wire harnesses as possible are docked with the regional controller, and the wire harnesses in the same segment are docked with one interface of the second interface layout to the greatest extent.

[0074] As an optional implementation, after the target wire harnesses in different segments are connected through the wire harness connector, the method further comprises: adjusting a wire-wire connection scheme according to the interface information of the vehicle electrical device, wherein the wire-wire connection scheme is a scheme of connecting the target wire harnesses in different segments through the wire harness connector; adjusting the second interface layout of the regional controller according to the adjusted wire-wire connection scheme; and docking the automobile wire harnesses outside the adjusted wire-wire connection scheme with the interfaces in the adjusted second interface layout.

[0075] In the present application, during the development process of the automobile project, the vehicle electrical device changes, at this time, the server determines the interface information of the vehicle electrical device. Some wire harnesses that cannot be directly docked with the regional controller can be directly docked with the interfaces of the regional controller after the interface information changes, so it is necessary to adjust the wire-wire connection scheme to reduce the length of the automobile wire harnesses.

[0076] The regional controller and the wire harness connector connect all the wire harnesses in the automobile wire harnesses, so that the second interface layout of the regional controller is also adaptively adjusted after the wire-wire connection scheme is adjusted. At this time, the interfaces in the adjusted second interface layout are docked with the automobile wire harnesses outside the adjusted wire-wire connection scheme.

[0077] In the present application, with the progress of the development of the automobile project, the wire-wire connection scheme is adjusted based on the interface information of the vehicle electrical device, so that the second interface layout of the regional controller is adjusted. The present application can reduce the length of the automobile wire harnesses by continuously adjusting and optimizing the interface layout of the regional controller.

[0078] As an optional implementation, adjusting the wire-wire connection scheme according to the interface information of the vehicle electrical device comprises: determining the interface information of the vehicle electrical device during the development process of the automobile project; determining the wire harnesses docked with the electrical device according to the interface information; if it is determined according to the interface information that the first wire harness and the second wire harness are connected through a non-regional controller and the second wire harness and the third wire harness are connected through a wire harness connector, wherein the second wire harness is docked with the interface of the first regional controller, and the third wire harness is docked with the interface of the second controller; adjusting the first wire harness to be docked with the interface of the first regional controller, wherein information is interchanged between different regional controllers.

[0079] In the present application, as the automobile project development process is continuously promoted, the automobile electrical devices will also be adjusted, and the interface information of the electrical devices may also be adaptively changed. At this time, the wire harness for the interface docking of the changed electrical devices is determined.

[0080] Exemplarily, as shown in Figure 2 The original interface information is that wire harness A3 and wire harness A1 are both cabin wire harnesses, wire harness A1 is connected with wire harness D3 through a wire harness connector, at this time there is no wire harness D1, wire harness A1 is docked with the interface of zone controller Zone1, and wire harness D3 is docked with the interface of zone controller Zone3. At this time, one wire harness connector is used, and the wire harness length A1-D3 is needed.

[0081] If wire harness D1 is added in the project development process, and wire harness D1 is docked with the interface of zone controller Zone1, at this time, it can be adjusted that wire harness A3 is connected with wire harness A1. Since the zone controller Zone1 and the zone controller Zone3 are connected through wire harness D1 and wire harness D3 to realize conduction and information intercommunication, and the interface of wire harness A1 and Zone1 is docked, wire harness A3 is essentially connected with the zone controller Zone3.

[0082] Through the adjustment, the connection between wire harness A1 and wire harness D3 is omitted, the wire harness length is saved, and the wire harness connector between wire harness A1 and wire harness D3 is also omitted. In the automobile project development process, by adjusting the wire harness connection scheme, the wire harness length can be saved, the number of wire harness connectors can be reduced, and the cost can be reduced.

[0083] As an optional implementation, according to the adjusted wire harness connection scheme, adjusting the second interface layout of the zone controller includes: determining remaining wire harnesses not contained in the adjusted wire harness connection scheme based on the adjusted wire harness connection scheme; and adjusting the second interface layout of the zone controller according to the remaining wire harnesses, wherein the number of docking combinations formed by the remaining wire harnesses and the adjusted second interface layout is the largest.

[0084] After the adjustment of the wire harness connection scheme, the wire harnesses other than the wire harnesses connected by the wire harness connector are taken as the remaining wire harnesses. Since the remaining wire harnesses change relative to the original segmented wire harnesses, the second interface layout of the zone controller also needs to be adjusted correspondingly, so that the wire harnesses in the same segment in the remaining wire harnesses dock with one interface of the adjusted second interface layout to the largest extent, so that the number of docking combinations is the largest.

[0085] Exemplarily, the present application provides a connection method between a zone controller and a wire harness, as shown in Figure 2 .

[0086] In the embodiment, three zone controllers are taken as the core, wherein the Zone1 and the Zone2 are arranged at the left and right A pillars respectively, and the power distribution and control functions of the electrical components or secondary controllers (the next level controllers of the zone controllers) in the left and right regions are realized respectively.

[0087] The zone controller Zone1 and the zone controller Zone2 are arranged at the left and right A pillars of the automobile respectively, and the zone controllers have the function of the concentrator, so that the information interaction and processing of the cabin region, the door region, the chassis region and the instrument region are realized at the left and right A pillars through the Zone1 and the Zone2.

[0088] In the embodiment, the connection mode of the wire harness segments is as follows.

[0089] The A is a cabin wire harness, including A1, A2, A3 and A4. The A1 and the A2 are connected with the right zone controller Zone1 and the left zone controller Zone2 respectively, the A3 is connected with the front bumper wire harness F1, and the segmentation mainly considers the assembly process; and the A4 is connected with the front drive wire harness G1.

[0090] The C is an instrument wire harness, including C1 and C2. The C1 and the C2 are connected with the right zone controller Zone1 and the left zone controller Zone2 respectively, the C1 and the C2 produce information interaction with the Zone1 and the Zone2 according to the corresponding functional requirements, and since the C1 and the C2 are connected, the information transmission between the Zone1 and the Zone2 can be realized through the instrument wire harness C.

[0091] The D is a chassis wire harness, including D1, D2, D3, D4, D5, D6, D7 and D8. The D1 and the D2 are connected with the right zone controller Zone1 and the left zone controller Zone2 respectively, the D3 and the D4 are connected with the zone controller Zone3, so that the information interaction among the Zone1, the Zone2 and the Zone3 can be realized through the chassis wire harness D, and the control function redistribution of the zone controllers can be balanced. In particular, the Zone3 is mainly responsible for the power distribution and control functions of the electrical components or secondary controllers in the rear half region of the vehicle body, so as to reduce the length of the wire harness and the like. The D5 is connected with the right rear door wire harness N1, the D6 is connected with the left rear door wire harness M1, and the segmentation mainly considers the assembly process of the rear door wire harness. The D7 is connected with the rear bumper wire harness K1, and the segmentation mainly considers the assembly process of the rear bumper. The D8 is connected with the rear drive wire harness H1 at the right rear of the vehicle, and the segmentation mainly considers the assembly process of the rear drive wire harness.

[0092] The left front door wire harness E1 is connected with the left zone controller Zone2, and the right front door wire harness B1 is connected with the right zone controller Zone1. The wire harness connector between the traditional door wire harness and the chassis wire harness is reduced to reduce the cost under the requirement of the assembly process.

[0093] The above-mentioned consideration of the assembly process of the wire harness refers to placing the wire harness in the corresponding wire harness mounting position according to the type of the wire harness.

[0094] Figure 3 The schematic diagram of the wire harness connection scheme corresponding to Zone1 is shown to illustrate the wire harness connection and the wire harness-controller connection relationship under the right A pillar.

[0095] In the embodiment, the nacelle wire harness has four connection connectors (a1, a2, a3, a4), the chassis wire harness has four connection connectors (d1, d2, d3, d4), the instrument wire harness has three connection connectors (c1, c2, c3), and the right front door wire harness has two connection connectors (b1, b2).

[0096] In the embodiment, a1, b1, c1, and d1 are directly connected with the zone controller Zone1, and correspond to Figure 2 Zone1 is connected with the wire harnesses A1, B1, C1, and D1, but in the wire harness segment connected with Zone1, there is an interaction relationship, and the loop does not need to enter the zone controller.

[0097] Therefore, the nacelle-instrument (a2-c2), the nacelle-chassis (a3-d3), and the instrument-chassis (c3-d2) are set as the connection loops of the three wire harness connectors, and the number of the connection loops of the wire harness connectors is determined by the integration degree of the zone controller. In particular, the inline segment points of special wire harnesses such as cameras are set, such as the front camera of the nacelle wire harness and the camera of the door wire harness, which are connected at the chassis wire harness d4. The connection points are determined according to the position of the controller receiving the video signal. In the embodiment, Zone1 does not directly receive and process the video signal.

[0098] The zone controller has a plurality of function modules, and the function modules include a power module, a communication module, a driving module, a signal module, a processor module, and a power distribution module.

[0099] The power module is used to receive the whole vehicle primary power distribution of the nacelle fuse box and the power supply of each module in the controller.

[0100] The communication module is used for Ethernet communication, CANFD (CAN with Flexible Data-Rate) communication and CAN communication with other area controllers and peer controllers, and can also perform LIN (Local Interconnect Network) communication with lower-level devices. The communication module integrates a traditional gateway controller and can realize communication protocol conversion, data exchange and filtering protection.

[0101] The driving module is used for outputting driving signals to lower-level devices, and the driving mode includes high-side driving and H-bridge driving.

[0102] The signal module is used for signal acquisition of the next-level device, which includes an external device chassis and a power sensor. The signal module is internally provided with a PIS5 transceiver and uses a PIS5 communication protocol for signal transmission.

[0103] The micro control unit module (MCU) is used for processing node information of each module and can also perform decision control. The arrangement position of the connector in the micro control unit module should consider the connection mode with each segmented wire harness to avoid wire harness cross installation.

[0104] The power distribution module is a two-level power distribution center, which is used for providing power output to sensors, controllers and actuators in the area, and uses an intelligent electronic programmable fuse (eFuse) to realize intelligent power distribution.

[0105] Figure 4 It is an electrical interface distribution diagram of the area controller. Figure 4 It includes K1-K8 connectors in total, wherein K1 is a power connector, K2-K6 are signal connectors, and K7 and K8 are communication interface connectors. The distribution of the connector pin should consider multiple factors such as PCB layout, PCB wiring, signal shielding, heat dissipation, electromagnetic compatibility and signal integrity.

[0106] The eight connectors are arranged according to the wire harness segmentation, the distribution position of the function module of the controller on the circuit board and the wiring of the controller PCB. In particular, the power connector and the communication interface connector are separately arranged considering electromagnetic compatibility and signal integrity.

[0107] K1 is a power connector. According to the direction of the vehicle power wire harness, the wire harness end can be arranged on a suitable wire harness segment. According to the power consumption parameters of the area controller, the connection mode with the corresponding wire harness segment is set, including but not limited to bolt connection.

[0108] K7 and K8 are communication interface connectors, which are generally 100 Mbps or 1 Gbps Ethernet connectors to realize Ethernet communication with other area controllers and peer controllers.

[0109] K2-K6 are signal connectors, which respectively realize the butt joint with the cabin wire harness, the chassis wire harness, the door wire harness and the instrument wire harness.

[0110] Based on the same technical concept, the application further provides a signaling diagram for automobile wire harness connection, as shown in the following steps. Figure 5

[0111] Step 501: In the initial stage of the project, the regional controller collects information of parts to determine a first interface layout.

[0112] Step 502: A preliminary segmentation scheme of the automobile wire harness is determined.

[0113] Step 503: According to the preliminary segmentation scheme, the first interface layout of the regional controller is adjusted to obtain a second interface layout.

[0114] Step 504: A target wire harness is obtained.

[0115] Step 505: The target wire harness in different segments is connected through a wire harness connector.

[0116] Step 506: In the development stage of the project, the wire-wire connection scheme is adjusted according to the interface information of the whole vehicle electrical device.

[0117] Step 507: The second interface layout of the regional controller is adjusted according to the adjusted wire-wire connection scheme.

[0118] Step 508: The interfaces in the adjusted second interface layout are used to butt joint with the automobile wire harnesses other than the adjusted wire-wire connection scheme.
