[0046] The vehicle electrical control assembly 400 is used in a hybrid vehicle 1, which refers to a vehicle having two power sources. Specifically, the hybrid vehicle 1 includes an engine and at least one drive motor, at least one of which can provide driving force to the hybrid vehicle 1 to move the vehicle. The hybrid vehicle 1 also includes a gearbox connected to the engine and / or the drive motor, a transmission shaft, and the like, which are used to achieve torque adjustment and power transmission.

[0047] The frame 460 is a frame structure of the vehicle electrical control assembly 400, which is used to form an accommodation space. Specifically, the frame 460 includes a first accommodation cavity 461 and a second accommodation cavity 462, the first accommodation cavity 461 accommodating the chassis distribution box 440 and the low-voltage storage battery 450, and the second accommodation cavity 462 accommodating the power domain controller 410, the power battery 420, and the high-voltage distribution box 430.

[0048] The power battery 420 is used to provide electrical energy to the vehicle, and can be, for example, a ternary lithium power battery, a lithium iron phosphate power battery, or the like. The power domain controller 410 is used to achieve intelligent control of the hybrid vehicle 1, and the basic control unit of the power domain controller 410 is a vehicle control unit VCU (Vehicle Control Unit), which can achieve functions such as hybrid mode switching, engine control, energy recovery and management, state monitoring, fault diagnosis, communication interaction, and the like of the hybrid vehicle 1.

[0049] Further, the power domain controller 410 can also integrate at least one of a transmission control unit TCU (Transmission Control Unit), a motor control unit MCU (Motor Control Unit), a high-voltage distribution box control unit, and a high-low voltage direct current conversion unit DC / DC (Direct Current-Direct Current Converter). The transmission control unit TCU is used to control the gear shifting operation and transmission ratio adjustment of the vehicle gearbox to achieve optimal power transmission of the vehicle under different driving conditions. The motor control unit MCU is used to accurately control the operation of the drive motor, including the speed, torque, and steering of the motor. The high-voltage distribution box control unit is a control module of the high-voltage distribution box 430PDU (Power Distribution Unit), which is used to achieve high-voltage control of the high-voltage distribution box 430 and distribute high-voltage power to various systems or components that require high-voltage power, such as drive motors, air conditioning compressors, and the like. The high-low voltage direct current conversion unit DC / DC is used to convert high-voltage direct current of the hybrid vehicle 1 into low-voltage direct current to provide stable power supply for various low-voltage electrical equipment on the hybrid vehicle 1, such as vehicle-mounted electrical equipment, control systems, and the like.

[0050] The high-voltage distribution box 430 is configured to protect and control the output of high-voltage electricity from the power battery 420 and transmit the high-voltage electricity to high-voltage electrical components. The chassis distribution box 440 is configured to distribute electrical energy to various low-voltage electrical devices on the chassis 10, such as an electric power steering system, an electronic stability control system, an anti-lock braking system, a suspension system, and the like. The low-voltage storage battery 450 is configured to provide power for the low-voltage electrical system of the hybrid vehicle 1. It should be noted that in the electrical system of the commercial hybrid vehicle 1, high voltage refers to a voltage exceeding 60 volts, for example, 300-1000 volts, and low voltage refers to a voltage of 12 volts or above (including 12 volts) to 60 volts (including 60 volts) below, for example, 12V, 24V, 48V, and the like.

[0051] In the present application, the power domain controller 410, the plurality of high-voltage components such as the high-voltage distribution box 430 and the power battery 420, and the plurality of low-voltage components such as the chassis distribution box 440 and the low-voltage storage battery 450 are integrated to form the vehicle electrical control assembly 400. Compared with the prior art in which high and low voltage components are arranged separately on the chassis, the space and volume occupied can be reduced, and the number of components on the chassis can be reduced. In this way, the integration, modularity of the electrical system and the utilization rate of the chassis space are improved, and the structural compactness of the chassis and the convenience of component arrangement are also improved.

[0052] In addition, the vehicle electrical control assembly 400 of the present application also separates the high-voltage components from the low-voltage components. In this way, the risk of electromagnetic interference of the high-voltage components on the low-voltage components can be reduced, and the probability of damage to the low-voltage components caused by high-voltage leakage and the like can be reduced, thereby improving the safety and reliability of the vehicle electrical control assembly 400. Furthermore, the same type or closely related components are placed in the same accommodating cavity, which also improves the convenience of electrical connection between the closely related components and the convenience of maintenance, troubleshooting and fault diagnosis.

[0053] In some embodiments, as shown in Figure 4 The first accommodating cavity 461 includes a first sub-accommodating cavity 4611, a second sub-accommodating cavity 4612, and a third sub-accommodating cavity 4613 arranged in order from top to bottom, the chassis distribution box 440 is arranged in the first sub-accommodating cavity 4611, the low-voltage storage battery 450 includes a first sub-low-voltage storage battery 451 and a second sub-low-voltage storage battery 452, the first sub-low-voltage storage battery 451 is arranged in the second sub-accommodating cavity 4612, and the second sub-low-voltage storage battery 452 is arranged in the third sub-accommodating cavity 4613.

[0054] In this way, on the one hand, the chassis power distribution box 440 is located at the topmost position, facilitating the disassembly and installation of the chassis power distribution box 440, thereby facilitating the convenience and efficiency of the chassis power distribution box 440 maintenance, overhaul and troubleshooting. On the other hand, the capacity of the low-voltage storage battery 450 can be improved, thereby facilitating the reliability and stability of the low-voltage system. In addition, it is also conducive to improving the space utilization of the first accommodating cavity 461, thereby facilitating the compactness of the vehicle electrical control assembly 400.

[0055] In some embodiments, the second accommodating cavity 462 comprises a fourth sub-accommodating cavity 4621, a fifth sub-accommodating cavity 4622 and a sixth sub-accommodating cavity 4623 arranged in sequence from top to bottom, the power domain controller 410 is arranged in the fourth sub-accommodating cavity 4621, the power battery 420 comprises a first sub-power battery 421 and a second sub-power battery 422, the first sub-power battery 421 is arranged in the fifth sub-accommodating cavity 4622, the second sub-power battery 422 and the high-voltage power distribution box 430 are both arranged in the sixth sub-accommodating cavity 4623, and the high-voltage power distribution box 430 is located behind the second sub-power battery 422.

[0056] The embodiment proposes an arrangement mode of the power domain controller 410, the power battery 420 and the high-voltage power distribution box 430 in the second accommodating cavity 462. Among them, the power domain controller 410 is located at the topmost position, facilitating the disassembly and installation of the power domain controller 410, thereby facilitating the convenience and efficiency of the power domain controller 410 maintenance, overhaul and troubleshooting. In addition, the second accommodating cavity 462 is divided into a plurality of sub-accommodating cavities along the Z direction, which can reasonably utilize the space of the second accommodating cavity 462, reserving the installation space of the high-voltage power distribution box 430 while improving the battery capacity as much as possible, thereby facilitating the space utilization of the second accommodating cavity 462, and facilitating the compactness of the vehicle electrical control assembly 400.

[0057] In some embodiments, the extension directions of the first sub-power battery 421 and the second sub-power battery 422 are different. Optionally, the first sub-power battery 421 extends along the X direction, and the second sub-power battery 422 extends along the Y direction. In this way, it is conducive to further improving the space utilization of the second accommodating cavity 462.

[0058] In addition, arranging the chassis power distribution box 440, the low-voltage storage battery 450, the power domain controller 410, the power battery 420 and the high-voltage power distribution box 430 in the frame 460 in the above-mentioned manner is also conducive to improving the uniformity of the load distribution of the vehicle electrical control assembly 400.

[0059] The embodiment of the second aspect of the application proposes a chassis 10. As shown in Figures 1 to 4As shown, the chassis 10 comprises a frame assembly 100, a fuel tank assembly 300 and the vehicle electrical control assembly 400 of the first aspect, the frame assembly 100 extends along the X direction of the hybrid vehicle 1, the fuel tank assembly 300 is arranged at one side of the frame assembly 100, and the vehicle electrical control assembly 400 is arranged at the other side of the frame assembly 100.

[0060] The frame assembly 100 is the skeleton structure of the hybrid vehicle 1, and provides a mounting base for various components of the hybrid vehicle 1. The frame assembly 100 is usually welded by longitudinal beams and cross beams made of high-strength steel, and has high strength and rigidity, and can withstand the weight of the hybrid vehicle 1 itself, the weight of the goods and various stresses during driving.

[0061] The fuel tank assembly 300 refers to a module for storing liquid medium of the vehicle power chain, and can include a urea tank and at least one fuel tank. The urea tank is used for the aftertreatment system 500 of the hybrid vehicle 1, and the fuel tank is used to supply energy to the engine.

[0062] The chassis 10 of the present application uses the vehicle electrical control assembly 400 of the first aspect. In this way, the integration and modularity of the electrical system and the utilization rate of the chassis space are improved, and the structural compactness of the chassis and the convenience of component arrangement are also improved. In addition, the vehicle electrical control assembly 400 also separates the high-voltage components and the low-voltage components, thereby improving the safety and reliability of the vehicle electrical control assembly 400, and the convenience of maintenance, troubleshooting and the like. Furthermore, the fuel tank assembly 300 and the vehicle electrical control assembly 400 are respectively arranged at opposite sides of the frame assembly 100, which can reduce the space occupation above the frame, thereby improving the convenience of maintenance and the convenience of trailer installation of the hybrid vehicle 1. On the other hand, the load distribution on the chassis 10 is uniform, thereby improving the stability of the hybrid vehicle 1 during driving.

[0063] It should be noted that in the 6x4 specification hybrid commercial vehicle, the frame assembly 100 is a double longitudinal beam structure, the frame assembly 100 is divided into three regions along the Y direction of the hybrid vehicle 1, and in sequence, the left side region of the frame assembly 100, the region between the two longitudinal beams of the frame assembly 100, and the right side region of the frame assembly 100. The left side is the side where the driver's seat is located, and the 6x4 specification refers to a chassis structure with six wheels (three groups of axles) and four drive wheels, which is commonly used in heavy-duty tractors. Among them, the vehicle electrical control assembly 400 is arranged on the other side of the frame assembly 100 along the Y direction of the center axis, that is, the vehicle electrical control assembly 400 can be arranged on the left side region or the right side region of the frame assembly 100, or part of the vehicle electrical control assembly 400 is arranged on the left side region or the right side region of the frame assembly 100, and a small part extends to the region between the two longitudinal beams of the frame assembly 100.

[0064] Optionally, the vehicle electrical control assembly 400 is arranged on the right side of the frame assembly 100, and the fuel tank assembly 300 is arranged on the left side of the frame assembly 100.

[0065] As shown in Figures 1 to 3 In some embodiments, the chassis 10 further includes a front axle 200, a middle axle 210 and a rear axle 220 connected with the frame assembly 100, the front axle 200, the middle axle 210 and the rear axle 220 are connected with the frame assembly 100 in sequence along the X direction, and the fuel tank assembly 300 and the vehicle electrical control assembly 400 are both located between the front axle 200 and the middle axle 210.

[0066] The front axle 200, the middle axle 210 and the rear axle 220 jointly bear the weight of the hybrid vehicle 1. The front axle 200 is integrated with a steering system for realizing the steering of the hybrid vehicle 1. Two of the front axle 200, the middle axle 210 and the rear axle 220 are electric drive axles, which cooperate with the engine to realize the hybrid driving of the hybrid vehicle 1. Optionally, in some embodiments, the front axle 200 and the rear axle 220 are both connected with a drive motor, that is, the front axle 200 and the rear axle 220 are integrated electric drive axles.

[0067] It can be understood that the size along the X direction between the front axle 200 and the middle axle 210 is the largest. In this way, the volume and size of the fuel tank assembly 300 and the volume and size of the vehicle electrical control assembly 400 can be increased as much as possible without interference, thereby further facilitating the improvement of the endurance of the hybrid vehicle 1. In addition, the above distribution of the two can also evenly distribute the load on the chassis 10, thereby further facilitating the improvement of the stability of the hybrid vehicle 1 in driving.

[0068] In some embodiments, as shown in Figure 1As shown, the fuel tank assembly 300 comprises a housing 310, and a first chamber 320, a second chamber 330 and a third chamber 340 arranged in the housing 310 in sequence from front to back, the first chamber 320 is configured as a urea chamber, the second chamber 330 is configured as a main fuel chamber, and the third chamber 340 is configured as an auxiliary fuel chamber.

[0069] In this way, on the one hand, the urea chamber and the two fuel chambers are integrated into the fuel tank assembly 300, which can reduce the occupied space, increase the fuel volume, and thus improve the endurance of the hybrid vehicle 1 compared to separately arranging the urea tank and the fuel tank. On the other hand, the space utilization of the chassis 10 can be further improved, thereby facilitating the compactness of the chassis 10. In addition, the present embodiment provides two fuel chambers, i.e., the chassis 10 has a dual-tank system, which is also conducive to improving the flexibility of the vehicle in terms of fuel use.

[0070] Alternatively, in other embodiments, only two chambers are arranged in the housing 310, which are a urea tank chamber and a fuel tank chamber. In this case, the chassis 10 is a single-tank system.

[0071] In some embodiments, as shown in Figure 3 The chassis 10 further comprises an aftertreatment system 500 arranged on the side connected to the frame assembly 100, the aftertreatment system 500 is arranged on the same side as the vehicle electrical control assembly 400, and the aftertreatment system 500 is located in front of the vehicle electrical control assembly 400.

[0072] The aftertreatment system 500 is used to purify the exhaust gas of the hybrid vehicle 1 to meet the requirements of the national standard.
