Description:A VEHICLE WITH PLURALITY OF ELECTRONIC CONTROL UNITS
FIELD OF THE INVENTION
[0001] The present invention disclosure to an engine assembly of a vehicle. More particularly, the present disclosure relates to a location of at least one electronic 5 control unit of the plurality of electronic control units in the vehicle.
BACKGROUND
[0002] In the development of electric and hybrid vehicles, controllers have risen to prominence while undertaking critical electrical network operations. The 10 controllers are devices or groups of devices that can coordinate, in a predetermined manner, the performance and operation of one or more electric components of the vehicle. The controllers of much importance can include but are not limited to Vehicle Control Unit, Telematics Control unit, Body Control Unit, and Motor Control Unit. The Vehicle Control Unit is in charge of overall control, coordination, 15 and monitoring of the running state of the vehicle. Further, the complex nature of these electronic components necessitates careful consideration in their integration within the vehicle architecture. More specifically, challenge lies in finding efficient and space-effective arrangements to house these controllers, ensuring not only their optimal functionality but also addressing issues related to space constraints, thermal 20 management, and accessibility.
[0003] In the consideration where the controller is placed near the motor to minimize the length of wires and cables, several challenges emerge due to the environment in which the motor operates. Vibrations and heat generated by the motor can have adverse effects on the functioning of the controller. Vibrations can 25 induce mechanical stresses on the controller components, potentially leading to premature wear and failure. Additionally, excessive heat from the motor can affect the thermal management capabilities of the controller, leading to overheating and subsequent performance degradation or even failure.
[0004] Conventional vehicle encounter difficulties in effectively incorporating and 30 accommodating multiple controllers into the vehicle. The confined spaces within vehicles pose significant hurdles for engineers and designers seeking to balance the need for compactness with the necessity for proper cooling and easy access.

Further, the positioning of controllers within the vehicle can impact the overall performance and user experience. Furthermore, the effective wire routing is a critical aspect of any vehicle’s electrical system. The successful functioning of electrical components relies on the reliable transmission of electrical signals. Therefore, the uneven placement of the one or more electronic components in the 5 vehicle will complicate the wire routing and increases the potential hazards. T
he lack of predefined cable routing makes servicing of the controllers a cumbersome and time-consuming task. Without organized routing, identifying and accessing these controllers becomes challenging, thus impeding the efficiency of maintenance and repair operations. This not only extends the downtime during service but also 10 increases the overall complexity of the process. Also, during the assembly of the vehicle, this conventional arrangement poses difficulties. The freely hanging cables from the controllers create a disorderly and cluttered environment, making it challenging for assembly personnel to work efficiently. This not only affects the assembly time but can also lead to errors and inconsistencies in the placement of 15 the controllers, potentially compromising the safety and functionality of the vehicle. [0005] The solution provided by the prior arts additionally fail to address issues related to the theft of controllers. Further, the various controllers are not disposed at an optimum distance so as to ensure efficient signal transmittance while at the 20 same avoiding any tendency of arcing and minimize the length of required wiring.
[0006] Given these challenges, there is an urgent requirement to optimize the positioning, arrangement, and management of one or more controllers within the vehicle architecture. These approaches should not only improve spatial utilization and thermal efficiency but also streamline accessibility for maintenance purposes. 25
[0007] The above information as disclosed in this background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Further limitations and disadvantages of conventional and traditional approaches will become apparent to 30 one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present disclosure and with reference to the drawings.

VCU is also one 25 of the costly components of the vehicle (100), accordingly, there is also a need to appropriately locate the same in the vehicle so that the same can be protected from theft or the like. The onboard charger (204) is an essential component in electric and plug-in hybrid vehicles, configured to manage the charging process of the vehicle's battery pack. Its primary functionality lies in converting the alternating 30 current (AC) from an external power source, typically a charging station or wall outlet, into direct current (DC) to recharge the vehicle's battery pack. The motor (206) serves as the primary source of propulsion, converting electrical energy into mechanical energy to drive the vehicle's wheels. The junction box (404) serves as
12
a central hub for connecting and distributing electrical power to various components and systems within the vehicle.
[00046] In one of the embodiments of the present disclosure, the electronic control units (202, 204, 206, 404) are located within a predefined region of the vehicle (100), specifically within the rear cabin (119) beneath the step structure (208). 5 Further, the VCU (202) of the plurality of electronic control units (202, 204, 206, 404) is positioned towards the right side of the vehicle (100) when viewed from the rear side (R), offering a balanced distribution and efficient utilization of space within the vehicle's architecture. This positioning optimizes spatial utilization and ensures ease of access for maintenance purposes, contributing to the overall 10 functionality and reliability of the vehicle (100).
[00047] The VCU (202) of the plurality of electronic control units (202, 204, 206, 404) is mounted closer or in a close proximity to at least one rear wheel (114) of the vehicle (100). More specifically, the VCU (202) of the plurality of electronic control units (202, 204, 206, 404) is mounted close to the right-side rear wheel of 15 the vehicle (100) when viewed from the rear side (R). This placement ensures that the VCU is optimally situated to monitor and regulate the vehicle's dynamics and performance, particularly concerning aspects related to the rear wheels' operation. By being positioned nearer to the rear wheel, the VCU can effectively manage factors such as traction control, stability, and braking systems, thereby enhancing 20 the vehicle's overall handling and safety. Further, this location minimizes wiring lengths, reducing potential signal interference and improving the responsiveness of the control systems.
[00048] In one of the embodiments of the present disclosure, the VCU (202) is located in the vicinity of at least one rear wheel (114) of the vehicle (100) offers 25 significant advantages in terms of cooling efficiency. More specifically, by situating the VCU (202) close to the rear wheel (114), a natural airflow pattern is utilized to dissipate heat generated during the unit's operation. As the vehicle (100) moves forward, air rushes past the rear wheel (114), creating a stream of airflow that will effectively cool the VCU. This passive cooling mechanism takes 30 advantage of the vehicle's motion, ensuring consistent airflow to prevent the VCU from overheating. Further, this approach eliminates the need for additional cooling mechanisms that could add complexity and weight to the vehicle, contributing to a more streamlined and efficient cooling solution.
13
[00049] In one of the embodiments of the present disclosure, the VCU (202) among the plurality of electronic control units (202, 204, 206, 404), is positioned below the passenger seat assembly (112) within the rear cabin (119) of the vehicle (100). This positioning is configured to optimize spatial utilization within the vehicle architecture, capitalizing on available space without compromising passenger 5 comfort or safety. Further, by positioning the VCU beneath the passenger seat, it remains discreet and out of sight, contributing to a clean and uncluttered cabin appearance. Furthermore, this location shields the VCU from potential damage due to external impacts or vibrations but also offers a degree of theft protection, as it's less visible and accessible to unauthorized individuals. This placement also serves 10 to minimize wiring length and voltage drop, as the VCU is situated in close proximity to other electronic control units such as but not limited to motor, junction box, contributing to enhanced efficiency and reliability of the vehicle's electrical system.
[00050] In one of the embodiments of the present disclosure, a cooling unit is 15 implemented with the plurality of electronic control units (202, 204, 206, 404), more specifically with the VCU (202). The cooling unit comprising at least one cooling fan which is positioned behind the VCU (202). This cooling unit is configured to regulate the temperature of the ECUs, mitigating the risk of overheating and ensuring optimal performance and longevity. Further, by placing 20 the cooling fan behind the ECUs facilitates efficient heat dissipation by expelling hot air generated during the operation of these electronic components. Furthermore, the positioning of the cooling fan behind the ECUs minimizes the risk of obstruction or interference with other vehicle components, ensuring smooth airflow and effective cooling without compromising the overall layout or functionality of 25 the vehicle. In one of the embodiments of the present disclosure, the at least one cooling fan which is positioned behind the VCU (202) is facing towards the first cross member (302). More specifically, the at least one cooling fan is facing towards the partition wall (206) of the vehicle (100).
[00051] In one of the embodiments of the present disclosure, the at least one cooling 30 fan cooling fan is utilized either as an exhausted unit or as a blower unit, depending on the specific configuration and requirements of the vehicle's electronic control system. When serving as an exhausted unit, the cooling fan is positioned to expel hot air generated by the VCU, assisting in the removal of heat from the vehicle's
14
interior. This configuration promotes efficient thermal management by facilitating the extraction of hot air away from the VCU, thereby helping to prevent overheating and maintain optimal operating conditions for these critical components. On the other hand, in scenarios where the cooling fan functions as a blower unit, it is employed to circulate cool air within the vicinity of the VCU. By directing airflow 5 towards the electronic control units, the blower unit aids in dissipating heat and maintaining a consistent temperature, thus contributing to the overall cooling efficiency of the system. This configuration is particularly beneficial in environments where ambient temperatures are elevated or where additional cooling is required to ensure the proper functioning of the VCU. 10 [00052] In one of the embodiments of the present disclosure, the at least one cooling fan cooling fan is controlled based on real-time temperature data obtained from one or more temperature sensors. These sensors such as but not limited to thermistors, thermocouple, infrared temperature sensors, are intricately integrated within the plurality of electronic control units (202, 204, 206, 404), more specifically the VCU 15 (202), allowing for precise monitoring of the temperature conditions. As the temperature within the VCU fluctuates during operation, the temperature sensors continuously gather data to assess thermal conditions. When the temperature exceeds predetermined thresholds, signalling potential overheating, the cooling fan is automatically activated to facilitate heat dissipation. This dynamic cooling 20 mechanism ensures that the VCU remain within optimal temperature ranges, mitigating the risk of overheating-related malfunctions and safeguarding the overall performance and reliability of the vehicle's electrical systems.
[00053] In one of the embodiments of the present disclosure, a cover assembly (not shown) is introduced to encapsulate the plurality of electronic control units (202, 25 204, 206, 404), more specifically the VCU (202), of the vehicle (100). This cover assembly provides protection and containment for the ECUs, shielding them from external elements and potential damage, and also enhances the overall aesthetic and organization of the vehicle's interior space. Further, the cover assembly is operatively connected to the frame assembly (300) of the vehicle (100), establishing 30 a secure and integrated arrangement. This connection allows for convenient accessibility to the VCU when necessary for maintenance or servicing.
[00054] In one of the embodiments of the present disclosure, the structural integrity of the vehicle (100) is reinforced through a series of cross members (302, 306, 406)
15
integrated into the frame assembly (300) of the vehicle (100). These cross members, designated as the first
cross member (302), second cross member (406), and third cross member (306), serve to enhance the overall stability and strength of the vehicle's framework. More specifically, the second cross member (406) is positioned between the first (302) and third (306) cross members, effectively 5 bridging them to distribute load and stress more evenly across the frame. Further, the third cross member (406) is situated at the rear side (R) of the vehicle, further fortifying the framework against potential rear-end collisions or other rearward forces. [00055] In one of the embodiments of the present disclosure, the
VCU (202) of the 10 plurality of electronic control units (202, 204, 206, 404) is responsible for managing various vehicle functions, is positioned on the first cross member (302) within the vehicle's frame assembly. This placement is achieved through the utilization of a plurality of fastening units (304-1 and 304-2) which secure the VCU firmly onto the first cross member. The said placement of the VCU on the first cross member 15 ensures optimal placement for facilitating efficient communication and coordination with other vehicle systems and provides a stable and secure foundation for the VCU, minimizing vibration and ensuring reliable performance even under challenging conditions. Further, this will help to streamline the wiring harness layout, reducing complexity and enhancing the overall efficiency of the vehicle's 20 electrical system.
[00056] In one of the embodiments of the present disclosure, a structural enhancement is introduced to the vehicle's frame assembly through the inclusion of connecting arms (not shown) positioned over one or more electronic control units (202, 204, 206, 404), more specifically over the VCU (202).

[00057] In one of the embodiments of the present disclosure, a structural arrangement is introduced to manage and secure the wiring harness connected to
the plurality of electronic control units (202, 204, 206, 404) within the vehicle (100). More specifically, at least one cable clamp bracket (402) is positioned in front of the at least VCU (202) of the plurality of electronic control units (202, 204, 5 206, 404). The at least one cable clamp bracket (402) serves as a mounting mechanism, securing the wiring harness that emanates from the VCU (202) and preventing it from dangling or becoming disorganized. Further, the cable clamp bracket (402) is mounted over the second cross member (406) within the vehicle's frame assembly (300). This will ensure optimal spatial utilization and structural 10 integration, as the at least one cable clamp bracket (402) is affixed to a stable and centrally located component of the vehicle's frame. Furthermore, at least one cable clamp bracket (402) is equipped with multiple cable clips configured to support and organize the various cables originating from the VCU (202). These clips effectively manage the routing of cables, preventing tangling or interference with other vehicle 15 components. Accordingly, the cable clamp bracket enhances the reliability and durability of the vehicle's electrical systems, ensuring seamless operation and minimizing the risk of malfunctions due to loose or damaged wiring.
[00058] In one of the embodiments of the present disclosure, a cushioning unit is integrated into the mounting arrangement of the plurality of electronic control units 20 (202, 204, 206, 404) to protect the same from the vibrations experienced within the vehicle (100). This cushioning unit serves as a buffer between the VCU and the vehicle's frame, absorbing and dampening vibrations before they reach the electronic components. The cushioning unit typically consists of resilient materials such as rubber or foam that possess excellent shock-absorbing properties. Further, 25 the cushioning unit can be customized to accommodate the VCU's form factor and mounting requirements. It may consist of a flexible mounting bracket or a specially configured housing embedded with vibration-absorbing materials. This approach ensures a secure and stable installation while maximizing the effectiveness of vibration isolation. 30
[00059] The present disclosure offers several advantages by locating the Vehicle Control Unit (VCU) (202) within the vehicle architecture. More specifically, by positioning the VCU below the passenger seat assembly in the rear cabin, the same will optimizes spatial utilization within the vehicle, effectively utilizing the
17
available space and minimizing the impact on passenger comfort and cabin layout. With the VCU tucked away beneath the seat, valuable interior space is preserved, allowing for a more ergonomic and comfortable seating arrangement for occupants. Further, this placement of VCU allows for efficient utilization of interior space, which is especially crucial in modern vehicles where maximizing cabin room is a 5 priority. By capitalizing on the often-underutilized space beneath the seat, the VCU can be seamlessly integrated into the vehicle architecture without compromising passenger comfort or cabin aesthetics. [00060] By positioning the VCU below the passenger seat assembly reduces wiring harness length and complexity. With the VCU situated closer to other electronic 10 control units (ECUs) and components of the vehicle, the need for extensive wiring and cabling is minimized. This streamlined wiring configuration not only simplifies installation and maintenance processes but also reduces the likelihood of signal interference, voltage drops, and electromagnetic interference (EMI), thereby enhancing overall system reliability and performance. Additionally, the proximity 15 of the VCU to other ECUs facilitates efficient communication and coordination between various vehicle systems, optimizing control and responsiveness. The position of the VCU beneath the passenger seat assembly represents a departure from conventional placement methods typically found in vehicles. Traditionally, VCUs and other electronic control units are often mounted in more visible and 20 accessible locations within the vehicle, such as the dashboard or engine compartment. However, by choosing to conceal the VCU beneath the seat, the present disclosure introduces a novel approach that prioritizes space optimization, security, and protection from environmental factors.
[00061] By placing the VCU below the passenger seat assembly enhances security 25 and theft prevention. More specifically by situating the VCU in a less accessible and discreet location, the risk of unauthorized access or tampering is mitigated. This added layer of security helps safeguard sensitive electronic components and data, providing peace of mind to vehicle owners and operators. Unlike conventional mounting locations that may be more susceptible to unauthorized access or 30 tampering, the placement beneath the seat provides an added layer of protection. The location as disclosed in the present disclosure will reduces the risk of theft or vandalism directed towards the VCU, safeguarding critical electronic components and sensitive data housed within the vehicle's control system. Moreover, the VCU's
18
location beneath the seat offers inherent protection from environmental factors such as moisture, dust, and debris, shielding it from potential damage and ensuring reliable operation in various driving conditions. The location of the VCU as disclosed in the present disclosure enhances security and theft prevention.
