Description
ZONAL ELECTRONIC CONTROL UNIT (ECU) HAVING AUDIO AMPLIFIER ASSEMBLYTECHNICAL FIELD
[0001] The present disclosure relates to audio systems for vehicles.BACKGROUND
[0002] In automotive engineering, the network architecture of electronic control units (ECUs) in a vehicle plays an important role in how efficiently and effectively the systems of the vehicle operate. Domain architecture and zonal architecture are two primary types of vehicle network architectures.
[0003] The domain architecture organizes vehicle ECUs based on system functionalities. Domain controllers handle specific vehicle functions (e.g., powertrain, chassis, infotainment) that are within their domain and integrate related systems. For example, a powertrain domain controller manages engine and transmission systems whereas an infotainment domain controller manages radio, music, and navigation systems.
[0004] The zonal architecture organizes vehicle ECUs based on physical location or zones within the vehicle. Zonal ECUs associated with respective zones of the vehicle handle vehicle functions and integrate related systems that are specific to that zone. For example, a front-side zonal ECU manages all the different types of functions (e.g., both powertrain and infotainment functions) occurring in the front side of the vehicle whereas a rear-side zonal ECU manages all the different types of functions occurring in the rear zone of the vehicle.
[0005] Automotive engineering is increasingly moving to centralized processing and making use of the zonal architecture and zonal ECUs with a goal being to reduce the number of vehicle ECUs. This trend impacts the audio system of a vehicle as an audio amplifier of the audio system is conventionally arranged in a vehicle network architecture like a vehicle ECU.SUMMARY
[0006] The present disclosure provides an audio amplifier assembly that comports with the movement towards the use of the zonal architecture and zonal electronic control units (ECUs) . In this regard, the audio amplifier assembly is integrable into a zonal ECU for use within the zonal ECU. A zonal ECU having an audio amplifier assembly integrated therein is also provided.
[0007] The audio amplifier assembly may be assembled by populating pertinent audio amplifier electronic components onto a printed circuit board (PCB) and by depopulating non-pertinent electronic components off from the PCB when present. The PCB with the pertinent audio amplifier electronic components installed therein is a PCB assembly (PCBA) or PCB module. The audio amplifier assembly thus has an amplifier PCBA design. As the PCBA is relatively physically small, the audio amplifier assembly is considered as having a mini amplifier PCBA design.
[0008] The mini amplifier PCBA is configured to physically, flexible fit into a corresponding socket of a zonal ECU for assembly therein and thereby connect with zonal ECU PCBAs of the zonal ECU. In being assembled within the zonal ECU, the mini amplifier PCBA also connects with audio related components (e.g., head units, speakers, subwoofers, microphones, crossover, audio receivers, CD players, DVD players, in-dash GPS navigation, etc. ) that are otherwise connected to the zonal ECU. In this way, the audio amplifier assembly can be utilized to provide amplifier control circuit functions for the zone of a vehicle that is associated with the zonal ECU.
[0009] The mini amplifier PCBA has a modular design to have a reduced complexity. The mini amplifier PCBA provides amplifier functions and can easily fit (e.g., plug into) into a zonal ECU as a signal unit or to co-interact with other ECUs.
[0010] As set forth, the audio amplifier assembly represents a solution as to how audio amplifier hardware is to be associated with a zonal ECU and how the audio amplifier hardware is to mix with vehicle ECUs associated with the zonal ECU. Other advantages and features of the mini amplifier PCBA include the following. The mini amplifier PCBA hardware can be populated onto the PCB and depopulated out from the PCB relatively easily to precisely match the audio needs of an audio system of a vehicle. When integrated into a zonal ECU, subject to thermal requirements, the mini amplifier PCBA can share a heatsink of the zonal ECU. The mini amplifier PCBA may be assembled as a single unit thereby reducing hardware design workload for a vehicle assembler and thereby limiting the workload for integration of the mini amplifier PCBA into a zonal ECU. The mini amplifier PCBA reduces ECU’s hardware design quality risk by leveraging a reconfigurable modular design that can be scaled up and down.BRIEF DESCRIPTION OF THE DRAWINGS

As an example, as indicated in FIG. 2A, zonal ECU 34b is connected to two other ECUs 18a and another ECU 18b and to other sensors and actuators 20a and 20b. Accordingly, in this example, zonal ECU 34b is configured to control these ECUs and sensors and actuators which are physically located in the front, right-hand side of vehicle 10.
[0027] Referring now to FIGS. 2B and 2C, with continual reference to FIG. 2A, simplified and detailed schematic diagrams of zonal network 30 are shown. In the simplified schematic diagram of zonal network 30 in FIG. 2B, vehicle computer 32, zonal ECUs 34a, 34b, 34c, and 34d, and some of vehicle ECUs 18 are shown among other details.

[0030] As indicated above, in accordance with the present disclosure, zonal ECUs 34 have an audio amplifier assembly (or module) integrated therein.
[0031] Referring now to FIG. 3, a block diagram of an audio amplifier assembly 40 is shown. The block diagram of FIG. 3 depicts the logic (i.e., electronic hardware components) of audio amplifier assembly 40. Audio amplifier assembly 40 includes electronic components that are assembled onto a printed circuit board (PCB) 42. As such, as assembled, audio amplifier assembly 40 is a PCBA (e.g., “the mini amplifier PCBA” or “Mini AMP PCBA” ) . The electronic components of audio amplifier assembly 40 pertain to audio amplifier electronic components. Audio amplifier assembly 40 is thereby operable for controlling audio functions of a vehicle.
[0032] Audio amplifier assembly 40 is integrable into a zonal ECU 34. Audio amplifier assembly 40, when integrated into zonal ECU 34, connects to other vehicle ECUs 18 and sensors and actuators 20 that are located within the physical zone corresponding to the zonal ECU. In being connected to zonal ECU PCBAs of zonal ECU 34 and vehicle ECUs 18 and sensors and actuators 20, audio amplifier assembly 40 is operable for use in controlling and managing audio functions associated with such zonal ECU PCBAs, vehicle ECUs, and sensors and actuators.
[0033] The electronic components of audio amplifier assembly 40 as shown in FIG. 3 include first and second ECU connectors (ECU CN) 44a and 44b, an automotive audio bus interface (A2B I / F) 46, a first analog to digital converter (ADC) 48a, a second ADC 48b, a memory device (EEPROM) 50, a power line filter 52, an ACC circuit 54, a logic power circuit 56, a tracking power supply (TPS) circuit 58, a first audio amplifier IC (booster power integrated chip IC) 60 (e.g., Class D audio amplifier IC) , a second audio amplifier IC (battery level power IC) 62 (e.g., a Class D or Class AB audio amplifier IC) , a plurality of filter circuits (Filters) 64, and an internal connector (Internal CN) 66.

When audio amplifier assembly 40 is integrated into a zonal ECU 34, ECU connectors 44 connect with vehicle ECUs 18 that are in the physical zone corresponding to the zonal ECU to connect audio amplifier assembly 40 with these vehicle ECUs. Via ECU connectors 44, audio amplifier assembly 40 and vehicle ECUs 18 connected thereto can communicate (i.e., transfer and / or receive) signal inputs therebetween. That is, audio amplifier assembly 40 is operable for use in controlling and managing audio functions associated with vehicle ECUs 18 that are connected to the audio amplifier assembly via ECU connectors 44. As indicated, these vehicle ECUs 18 are the vehicle ECUs that are in the zone corresponding to zonal ECU 34 to which audio amplifier assembly 40 is integrated.
[0035] Similarly, internal connector 66 of audio amplifier assembly 40 is connectable with zonal ECU PCBAs 68 of a zonal ECU 34 to connect the audio amplifier assembly with these zonal ECU PCBAs. When audio amplifier assembly 40 is integrated into a zonal ECU 34, internal connector 66 connects with an internal connector 67 of zonal ECU PCBAs 68 of zonal ECU 34 to connect audio amplifier assembly 40 with these zonal ECU PCBAs. Via internal connectors 66 and 67, audio amplifier assembly 40 and zonal ECU PCBAs 68 of zonal ECU 34 connected thereto can communicate signal inputs therebetween. That is, audio amplifier assembly 40 is operable for use in controlling and managing audio functions associated with zonal ECU PCBAs 68 that are connected to the audio amplifier assembly via internal connectors 66 and 67. As indicated, these zonal ECU PCBAs 68 are the zonal ECU PCBAs of zonal ECU 34 to which audio amplifier assembly 40 is integrated.
[0036] Internal connector 66 is a flexible design option of audio amplifier assembly 40. On the one hand, when direct communications between audio amplifier assembly 40 and the zonal ECU PCBAs of a zonal ECU to which the audio amplifier assembly is integrated is to be conducted, internal connector 66 is used establish the communications with the zonal ECU PCBAs. On the other hand, when direct communications between audio amplifier assembly 40 and the zonal ECU PCBAs of a zonal ECU to which the audio amplifier assembly is integrated is not to be conducted, internal connector 66 is not used.
[0037] As set forth, ECU connectors 44 and internal connector 66 of audio amplifier assembly 40 are operable as ECU unit connectors. Internal connector 66 is operable as an ECU internal board connector for receiving signals from ECUs that are internal to other boards, for sending signals to the ECUs of the internal boards, and for bidirectional transferring signals with the ECUs of the internal boards.
[0038] Further details concerning the other electronic components of audio amplifier assembly 40 are as follows. Audio bus interface (A2B I / F) 46 includes an A2B audio network interface.

[0039] Referring now to FIG. 4, with continual reference to FIG. 3, a block diagram depicting a mounting control concept for use with audio amplifier assembly 40 is shown. The mounting control concept involves selectively populating pertinent audio amplifier electronic components onto PCB 42 of audio amplifier assembly 40 and depopulating non-pertinent electronic components out from the PCB to assemble the audio amplifier assembly. In this way, an assembler of audio amplifier assembly 40 can select which electronic components to mount on PCB 42. In FIG. 4, each electronic component encircled by a dotted line can be selectively mounted onto PCB 42 by the assembler.
[0040] Referring now to FIG. 5, a block diagram depicting audio amplifier assembly 40 integrated into a zonal ECU 34 (labeled “Zone ECU” in FIG. 5) is shown. Audio amplifier assembly 40 integrates into zonal ECU 34 by fitting or being plugged into a corresponding socket 92 of a housing 94 of the zonal ECU. This integration involves internal connector 66 of audio amplifier assembly 40 being plugged into internal connector 67 of zonal ECU PCBAs 68 (labeled “Zone ECU PCBAs” in FIG. 5) of zonal ECU 34 whereby the audio amplifier assembly and the zonal ECU PCBAs are connected.
[0041] In audio amplifier assembly 40 being integrated into zonal ECU 34, the audio amplifier assembly is directly connectable via ECU connectors 44 with vehicle ECUs 18 that are in the physical zone corresponding to the zonal ECU to connect the audio amplifier assembly with these vehicle ECUs. Likewise, in audio amplifier assembly 40 being integrated into zonal ECU 34, the audio amplifier assembly is directly connectable via internal connectors 66 and 67 with zonal ECU PCBAs 68 of the zonal ECU to connect the audio amplifier assembly with these zonal ECU PCBAs.

The development flow includes providing a design of audio amplifier assembly 40 and providing a design of zonal ECU 34, as indicated by process blocks 72 and 74. A thermal simulation of the audio amplifier assembly and zonal ECU designs is then performed as indicated by process block 76. Based on results of the thermal simulation, improvements including mechanical design improvements, may be made to the audio amplifier assembly and zonal ECU designs, as indicated by process block 78. The improved designs are then subject to various tests, such as mechanical engineering testing (e.g., material, vibration, stress / strain, fatigue, thermal, etc. ) , electromagnetic compatibility (EMC) testing (i.e., how well will the subject device function when exposed to electromagnetic interference) , environmental (ENV) testing, electrical (ELE) testing, and the like, as indicated by process block 80.
[0043] For system EMC and ENV testing, there are two cases. The first test case assumes that audio amplifier assembly 40 operates independently of zonal ECU 34. As such, the first test case is run with audio amplifier assembly 40 and a heatsink and / or cover of zonal ECU 34. The second test case assumes that audio amplifier assembly 40 operates together with zonal ECU PCBAs 68 of zonal ECU 34.
