The distribution module 150 distributes the low-voltage power supply to the low-voltage load access terminal. For example, in the case of multiple low-voltage load access terminals, power distribution is performed according to the power demand of the low-voltage load connected to each low-voltage load access terminal, and power distribution can also be performed according to the working status of the connected low-voltage load, thereby realizing dynamic adjustment of the output power of the low-voltage power supply and achieving the purpose of protecting the battery module 300 and the low-voltage load.

The controller 600 processes the sensor detection signal provided by the sensor interface 410, and controls the operation of the vehicle through the switch signal input through the switch input and output interface to achieve control of the entire vehicle.
[0107] In some embodiments, the electronic parking drive module 500 includes a caliper drive unit and an electronic handbrake unit, and the caliper drive unit and the electronic handbrake unit are controlled by the controller 600 to control the working state of the vehicle power load.
[0108] In this embodiment, the electronic parking control module 200 can control the caliper drive unit and the electronic handbrake unit at the same time to achieve control over the braking and parking of the vehicle.
[0109] In some embodiments, see Figure 8 As shown, the vehicle integrated controller architecture includes a first circuit board 123 and a second circuit board 124 , the vehicle control module 400 , the battery management module 100 , and the electronic parking control module 200 are integrated in the first circuit board 123 , and the power distribution module 150 is integrated in the second circuit board 124 .
[0110] In this embodiment, the vehicle control module 400, the battery management module 100 and the electronic parking control module 200 share the same controller 600. The battery management module 100 composed of the controller 600 and a part of its peripheral driving devices manages the status of the battery module 300. The vehicle control module 400 composed of the controller 600 and another part of its peripheral driving devices manages the power load of the vehicle. The electronic parking control module 200 composed of the controller 600 and another part of its peripheral driving devices manages the electronic parking drive module 500. The driving devices in the vehicle control module 400, the battery management module 100 and the electronic parking control module 200 are integrated on the first circuit board 123, and the relays or high-power devices in the power distribution module 150 are integrated on the second circuit board 124, which is conducive to simplifying the circuit and reducing the probability of wiring harness failure.
[0111] In this embodiment, since the vehicle control module 400, the battery management module 100, and the electronic parking control module 200 share the same controller 600, the controller 600 and the electronic parking drive module 500 constitute an electronic parking management circuit. Therefore, when the controller 600 is integrated into the first circuit board 123, the power distribution module 150 is integrated into the second circuit board 124 and connected to the controller 600 on the first circuit board 123 through a wiring harness. The power distribution module 150 supplies power to the first circuit board 123. The controller 600 performs vehicle control and electronic parking control on the same circuit board, which can reduce packet loss caused by data communication between circuit boards.
[0112] The battery management module 100 composed of the controller 600 and some of its peripheral driving devices manages the status of the battery module 300, and the power distribution module 150 composed of the controller 600 and another part of its peripheral driving devices controls the power distribution of the connected load. The vehicle control module 400 and the battery management module 100 are integrated on the first circuit board 123, and the controller 600 is also integrated on the first circuit board 123. This can avoid the problem that the original battery management module 100 and the vehicle control module 400 are independently set, resulting in a large number of wiring harnesses required to connect the circuit boards, and reduce the probability of wiring harness failure by simplifying the lines.
[0113] In some embodiments, the external pins of the controller 600 can not only form a vehicle control module 400 and a battery management module 100 with the driving device on the first circuit board 123, but can also form a power distribution module 150 with the DCDC circuit on the second circuit board 124, thereby achieving the effect of expanding the driving scheme.
[0114] In some embodiments, see Fig. 9 As shown, the vehicle integrated controller architecture also includes a vehicle radiator 160, a first circuit board 123 is disposed on a first side of the vehicle radiator 160, and a second circuit board 124 is disposed on a second side of the vehicle radiator 160, wherein the second side of the vehicle radiator 160 is opposite to the first side of the vehicle radiator 160.
[0115] In this embodiment, the first circuit board 123 and the second circuit board 124 are respectively arranged on both sides of the same vehicle heat sink 160. By sharing the same vehicle heat sink 160, the heat dissipation efficiency of the vehicle heat sink 160 can be improved and the volume of the vehicle can be reduced.
[0116] In some embodiments, the second circuit board 124 is disposed between the battery module 300 and the vehicle cooling plate 160 .
[0117] In this embodiment, by designing the second circuit board 124 to be close to the battery module 300, the power distribution module 150 can be made closer to the battery module 300, thereby realizing the management of the output power of the battery module 300, reducing the arrangement of high-current lines, and avoiding safety hazards caused by excessively long high-current wiring distances or complex signal line routing between the controller 600 and the battery module 300.
[0118] In some embodiments, a battery management module 100 composed of a controller 600 and a part of the driving devices on the first circuit board 123 manages the status of the battery module 300, and a power distribution module 150 composed of the controller 600 and another part of the driving devices on the second circuit board 124 controls the power distribution of the connected load. This can not only improve the heat dissipation efficiency of the driving devices, but also avoid the problem that the original battery management module 100, the power distribution module 150, and the vehicle control module 400 are independently set, resulting in a large number of wiring harnesses required for signal transmission and data communication between the circuit boards. By simplifying the lines, the probability of wiring harness failure and data packet loss is reduced.
[0119] In some embodiments, the external pins of the controller 600 can not only form a vehicle control module 400 and a battery management module 100 with the driving devices on the first circuit board 123, but also form a power distribution module 150 with the DCDC unit on the second circuit board 124, thereby achieving the effect of expanding the driving scheme.
[0120] In some embodiments, the controller 600 can also expand its external pins. For example, by soldering its external expansion pins to the expansion circuit on the first circuit board 123 and connecting the expansion circuit on the first circuit board 123 through multiple solder pads, the functions of the external expansion pins of the controller 600 can be customized and reused to achieve the purpose of vehicle function customization.
[0121] In some embodiments, see Fig.10 As shown, the battery module 300 is disposed on the second side of the vehicle heat sink 160 , and the second circuit board 124 is disposed between the battery module 300 and the vehicle heat sink 160 to dissipate heat together with the battery module 300 .
[0122] In this embodiment, a power distribution module 150 is provided on the second circuit board 124. By setting the second circuit board 124 between the battery module 300 and the vehicle heat sink 160, not only the wiring harness length between the battery module 300 and the driving device can be reduced, but also the temperature of the battery module 300 can be managed by integrating the relevant thermal management driving unit on the second circuit board 124, thereby reducing the signal transmission distance and reducing the size of the vehicle.
[0123] In some embodiments, see Fig.10As shown, the battery module 300 is arranged in the product lower cover 125, and the product lower cover 125 is a concave structure. The product lower cover 125 and the product upper cover 126 form a storage cavity. The first circuit board 123, the vehicle heat sink 160, and the second circuit board 124 are stacked on the battery module 300. The first circuit board 123, the vehicle heat sink 160, and the second circuit board 124 are fixed by an installation structure, wherein the distance between the first circuit board 123, the vehicle heat sink 160, the second circuit board 124 and the battery module 300 can be set according to the heat dissipation requirements and wiring harness requirements.
[0124] In some embodiments, the vehicle heat sink 160 can be a water-cooled plate, which is disposed between the first circuit board 123 and the second circuit board 124. After the vehicle is started, the heat emitted by the first circuit board 123 and the second circuit board 124 is absorbed by the water-cooled plate, thereby improving the space utilization efficiency inside the vehicle and reducing the size and volume of the vehicle's power distribution system.
[0125] In some embodiments, the controller 600 has at least two cores.
[0126] In this embodiment, the controller 600 has at least two cores, and multiple functions of the controller 600 can be distributed to multiple cores to improve the processing efficiency of the controller 600.

[0129] In some embodiments, at least one core of the controller 600 is used to process the sampling signal of the distribution module 150 to obtain sampling data, and at least one core of the controller 600 is used to generate control data based on the sampling data, and output a corresponding control signal based on the control data to control the distribution power of the distribution module 150.
[0130] In this embodiment, the controller 600 includes at least two cores, one or part of the cores can be used to process the sampling signal to obtain corresponding sampling data, and the other core or another part of the cores can be used to process the sampling data, obtain control data according to preset operations, and generate a control signal based on the control data and output it to the peripheral driving device, so as to control the distribution power of the low-voltage load by controlling the working state of the driving device.
[0131] In some embodiments, at least one core of the controller 600 is used to process the sampling signal of the vehicle control module 400 to obtain sampling data, and at least one core of the controller 600 is used to generate control data based on the sampling data, and output a corresponding control signal based on the control data to control the distribution power of the low-voltage load.
[0132] In this embodiment, the controller 600 includes at least two cores, one or part of the cores can be used to process the sampling signal to obtain corresponding sampling data, the other core or another part of the cores can be used to process the sampling data, obtain control data according to preset operations, and generate a control signal based on the control data and output it to the peripheral vehicle drive unit, so as to control the working state of the vehicle power load by controlling the working state of the vehicle drive unit.
[0133] In some embodiments, the controller 600 includes at least two cores. After the power distribution module 150, the battery management module 100 and the vehicle control module 400 reuse the same controller 600, the data collected by the sensor can be directly output to the controller 600 and processed uniformly by the controller 600. There is no need for the upper-level processor to send messages through the CAN bus, and there is no need to be affected by the outside world, thereby reducing the problem of information loss caused by message failure.
[0134] In some embodiments, the controller 600 controls multiple power loads to be powered on in time when the power distribution module 150 is connected to multiple power loads.
[0135] In this embodiment, multiple distribution modules 150 of the distribution module 150 can be connected to multiple power loads respectively. When multiple power loads are connected, the controller 600 can control the multiple power loads to power on in time, thereby meeting the power requirements of multiple low-voltage loads without increasing or significantly increasing the output current of the distribution module 150, thereby avoiding the problem of multiple distribution modules 150 being powered on at the same time, resulting in excessive output current and causing safety hazards.
[0136] In some embodiments, the output voltage range of the battery module 300 is 12V-72V.
