Description

Technical Field

[0001] This utility model belongs to the field of electronic control technology, and in particular relates to an engine wiring harness that can be adapted to a variety of electronic control systems. Background Technology

[0002] In modern automotive manufacturing, the engine, as the core power component of a vehicle, has an electronic control system that plays a crucial role in its performance, fuel economy, and emission control. With the continuous development of automotive technology, various engine electronic control systems from different manufacturers have emerged on the market, such as the Woodward system and the E-controls system. When producing vehicles with different configurations, OEMs need to adapt the corresponding engine wiring harnesses according to the selected engine electronic control system to ensure the normal operation of both the engine and the vehicle.

[0003] Currently, engine wiring harnesses are typically designed to be specifically adapted to the pinout of the electronic control unit (ECU) of a single electronic control system. For example, when adapting to the Woodward system, only the power supply and control pins of the sensors required by the system are considered. The starter control pins are directly connected to the starter motor, and start-stop control of the starter motor can be achieved without adding an additional starter relay. However, when adapting to the E-controls system, because the pinout of the ECU of this system is different from that of the Woodward system, the entire vehicle wiring harness needs to add an additional starter relay. Starter motor start-stop control is achieved by controlling the starter relay through the starter control pins.

[0004] However, this existing technology has obvious shortcomings. Since each electronic control system requires a separately designed and adapted engine wiring harness, when an OEM needs to replace the engine electronic control system, it often requires modifications to the entire vehicle wiring harness to varying degrees. This not only increases the overall vehicle design and manufacturing costs but also reduces production efficiency and brings many inconveniences to the OEM's parts design and management.

It should also be understood that additional or alternative steps may be used.

[0036] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another.

[0038] Currently, engine wiring harnesses are typically designed to be specifically adapted to the pinout of the electronic control unit (ECU) of a single electronic control system. For example, when adapting to the Woodward system, only the power supply and control pins of the sensors required by the system are considered. The starter control pins are directly connected to the starter motor, and start-stop control of the starter motor can be achieved without adding an additional starter relay. However, when adapting to the E-controls system, because the pinout of the ECU of this system is different from that of the Woodward system, the entire vehicle wiring harness needs to add an additional starter relay. Starter motor start-stop control is achieved by controlling the starter relay through the starter control pins.

[0039] However, this existing technology has obvious shortcomings. Since each electronic control system requires a separately designed and adapted engine wiring harness, when an OEM needs to replace the engine electronic control system, it often requires modifications to the entire vehicle wiring harness to varying degrees. This not only increases the overall vehicle design and manufacturing costs but also reduces production efficiency and brings many inconveniences to the OEM's parts design and management.

[0040] To address the issue that OEMs often need to modify the entire vehicle wiring harness to varying degrees when replacing the engine electronic control system, this invention proposes an engine wiring harness that is compatible with multiple electronic control systems. Figure 1A schematic diagram of an engine wiring harness structure adaptable to various electronic control systems according to an embodiment of the present invention is shown, including: a 62-pin engine wiring harness connector and an electronic control system ECU; the 62-pin engine wiring harness connector has multiple holes, and the electronic control system ECU has multiple conductive pins; wherein, the multiple holes include a first hole group for ensuring the consistency of vehicle functions for the same hole position of the connector, a second hole group for reducing the difference in power supply pins caused by different sensors, and a third hole group for ensuring that different electronic control systems achieve the same electronic control logic; the multiple conductive pins include a first conductive pin group for ensuring the consistency of vehicle functions for the same hole position of the connector, a second conductive pin for reducing the difference in power supply pins caused by different sensors, and a third conductive pin group for ensuring that different electronic control systems achieve the same electronic control logic; wherein, the first hole group is electrically connected to the first conductive pin group; the second hole group is electrically connected to the second conductive pin group; and the third hole group is electrically connected to the third conductive pin group.

[0041] The 62-pin engine wiring harness connector is a connector with 62 pins used to connect the engine wiring harness to the vehicle wiring harness. Each pin can be used to insert a conductive pin for transmitting electrical signals. For example, the 62-pin engine wiring harness connector... Figure 2 As shown.

[0042] The Electronic Control Unit (ECU) is the core component of the engine control system, responsible for receiving sensor signals and controlling actuator actions. An ECU typically has multiple conductive pins for connecting to the wiring harness. Holes are the insertion holes on connectors for inserting these conductive pins. Conductive pins are metal pins inserted into these holes to transmit electrical signals. Each conductive pin has a specific function, such as power supply, grounding, or signal transmission.

[0043] The first group of holes ensures consistent vehicle functionality for connectors with the same hole position. For example, by moving the pin position, different electronic control systems can achieve the same vehicle function at the same hole position. The second group of holes reduces power supply pin differences caused by different sensors. For example, by combining the power supply lines for the front oxygen sensor, EGR valve, and ECU into one hole position, the number and differences of power supply pins are reduced. The third group of holes ensures that different electronic control systems implement the same electronic control logic. For example, by configuring pin functions, different electronic control systems can implement the same control logic at the same hole position.

[0044] Specifically, the first conductive pin group is electrically connected to the first hole group to ensure consistent vehicle functionality. The second conductive pin is electrically connected to the second hole to reduce power supply pin differences. The third conductive pin group is electrically connected to the third hole group to ensure consistent electronic control logic.

[0045] For example, in the first group of pins: assuming pin 49 is used for power supply, by moving the pin positions, different electronic control systems can achieve the same power supply function on pin 49. In the second group of pins: assuming pin 50 is used for merging sensor power supply, the power lines for the front oxygen sensor, EGR valve, and ECU are merged into pin 50, reducing the number of power supply pins. In the third group of pins: assuming pins 51, 52, and 53 are used for signal transmission, by configuring the pin functions, different electronic control systems can achieve the same signal transmission logic on these pins.

[0046] In some embodiments of this application, the first hole group includes hole X1 numbered 1, hole X2 numbered 2, and hole X3 numbered 3; the first conductive pin group includes conductive pin Y1 identified as CAN3_H, conductive pin Y2 identified as CAN3_L, and conductive pin Y3 identified as T15; wherein hole X1 is electrically connected to conductive pin Y1, hole X2 is electrically connected to conductive pin Y2, and hole X3 is electrically connected to conductive pin Y3.

[0047] For example, the CAN3_H, CAN3_L, T15 pins of the E-controls system ECU should be connected according to the connection order of the Woodward system ECU and the 62-pin pins to ensure consistency.

[0048] As shown in Table 1.

[0050] In some embodiments of this application, the second hole is the X49 hole numbered 49; the second conductive pin is obtained by combining the sensor power supply pins of the front oxygen sensor power line, the EGR valve power line and the ECU power line; wherein, the X49 hole is electrically connected to the second conductive pin.

[0051] For example, the pins of the pre-oxygen power supply, EGR valve power supply, and ECU power supply are riveted together and connected to the 62-pin X49 socket. Figure 3 As shown, the left side represents the result after unification, and the right side represents the result before unification.

[0052] In some embodiments of this application, each third hole in the third hole group corresponds to the sensor requirements in the electronic control system ECU; each third conductive pin in the third conductive pin group corresponds to the sensor function in the electronic control system ECU.

[0053] Specifically, the third hole group includes an X37 hole for starter motor control, and the third conductive pin group includes starter motor control pins for starter motor control; wherein, the starter motor control pins are connected to the starter motor, and the X37 hole is connected to the starter motor.

[0054] For example, each hole is configured with pin functions according to the requirements of each sensor to ensure that different electronic control systems can achieve the same electronic control logic.

[0055] For example Figure 4 As shown, before standardization, the starter control of the E-controls system required the addition of a separate relay. For example... Figure 5 As shown, after the standardization was not achieved, the starter relay on the vehicle wiring harness was eliminated by configuring the pin function, so that no separate relay was needed for the whole vehicle.

[0056] In this embodiment, by adopting the design of this utility model, the 62-pin engine wiring harness connector is provided with multiple holes, including a first group of holes to ensure the consistency of vehicle functions for the same holes in the connector, a second group of holes to reduce the differences in power supply pins caused by different sensors, and a third group of holes to ensure that different electronic control systems achieve the same electronic control logic. The multiple conductive pins of the electronic control system ECU are also correspondingly divided into a first group of conductive pins, a second group of conductive pins, and a third group of conductive pins. Through this design, the first group of holes is electrically connected to the first group of conductive pins, the second group of holes is electrically connected to the second group of conductive pins, and the third group of holes is electrically connected to the third group of conductive pins. This unified hole definition and pin configuration allows a single vehicle wiring harness to adapt to different electronic control systems without the need for separate wiring harness design for each system, greatly improving the versatility and adaptability of the wiring harness and reducing design and manufacturing costs.

[0057] In some embodiments of this application, the electronic control system ECU is a Woodward system ECU or an E-controls system ECU.

[0058] In some embodiments of this application, multiple conductive pins are fixed to corresponding holes in multiple holes by crimping or riveting.

[0059] In some embodiments of this utility model, one end of the 62Pin engine wiring harness connector is electrically connected to the electronic control system ECU, and the other end of the 62Pin engine wiring harness connector is connected to the vehicle wiring harness. The vehicle wiring harness is the main body of the vehicle circuit for transmitting information between various vehicle components and controlling related vehicle electronic control equipment.

[0060] In some embodiments of this utility model, one end of the electronic control system ECU is connected to the 62-pin engine wiring harness connector, and the other end of the electronic control system ECU is connected to the engine's sensors and actuators to receive sensor signals and control the actuators to achieve the engine's electronic control function.

[0061] In some embodiments of this application, the housing of the 62Pin engine wiring harness connector is provided with a foolproof protrusion and a latch, the position and shape of which match the corresponding connector on the vehicle wiring harness side.

[0062] In this embodiment, the pin configuration of the 62-pin engine wiring harness connector and the ECU (Electronic Control Unit) is unified and standardized through the adoption of this design. This design allows a single vehicle wiring harness to be compatible with multiple electronic control systems, reducing the types and quantities of parts and simplifying inventory management, procurement, assembly, and after-sales maintenance processes. OEMs only need to manage one type of wiring harness, significantly reducing management costs and improving production and management efficiency.

[0063] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
