[0024] In combination with Figure 1 As shown, according to a specific embodiment of this application, a control system for a vehicle is provided.

[0025] Specifically, the control system includes a box body, an electric control module, a power supply module, an electric drive module, and a high-voltage power distribution module. The box body has a receiving cavity. The electric control module is disposed in the receiving cavity. The electric control module includes a motor controller and a first control board of the DC conversion control module. The control chip of the motor controller and the control chip of the first control board are integrated to form a first main control chip. The power supply module is disposed in the receiving cavity. The power supply module includes an AC charging control module and a first power board of the DC conversion control module. The control chip of the AC charging control module forms a second main control chip. The electric drive module is disposed in the receiving cavity. The electric drive module includes a motor and a speed reducer. The high-voltage power distribution module is disposed in the receiving cavity. The high-voltage power distribution module is electrically connected to the electric control module and the power supply module respectively.

[0026] In an embodiment of the present application, the electric control module, the power supply module, the electric drive module, and the high-voltage power distribution module of the vehicle are integrated in the same box body. Each module shares the box body, connectors, wire harnesses, and cooling system, saving the overall vehicle space and contributing to the development of the vehicle towards lightweight and miniaturization. Among them, the control chips of the motor controller and the first control board in the electric control module are deeply integrated, and the control chips of the AC charging control module in the power supply module are deeply integrated. By deeply integrating the control chips, the number of control chips is reduced, and then the number of compilers and debuggers corresponding to the control chips is reduced, reducing the development and maintenance costs. At the same time, the low-voltage power consumption of the control chips is also reduced. In the control system of the above solution, the integration degree of the control system is improved by deeply integrating the control chips, and the development cost and overall weight of the control system are further reduced.

[0027] It should be noted that the high-voltage power distribution module includes a high-voltage filtering module, a power distribution copper bar, and a fuse. The high-voltage power distribution module provides high-voltage electricity for the electric control module, the power supply module, and the electric drive module. The control chip of the motor controller and the control chip of the first control board are integrated to form a first main control chip, which means that at least one control chip of the motor controller and the control chip of the first control board are integrated to form a first control chip. The control chip of the AC charging control module forms a second main control chip, which means that at least one control chip of the AC charging control module forms a second main control chip.

[0028] It should be further noted that the box body is provided with an openable box door for maintaining and disassembling the modules in the box body.

[0029] In an exemplary embodiment of the present application, the box body is provided with a first chamber and a second chamber. The electric drive module is disposed in the first chamber, and the electric control module, the power supply module, and the high-voltage power distribution module are respectively disposed in the second chamber.

[0030] Specifically, the motor and the reducer in the electric drive module are mechanical components, and the control modules in the electronic control module, the power supply module, and the high-voltage power distribution module are electrical components. The mechanical components and the electrical components are separately arranged in two cavities to prevent the electromagnetic and heat generated during the operation of the electrical components from affecting the normal operation of the mechanical components, thereby improving the stability of the control system. In addition, the separate cavity arrangement facilitates the maintenance and repair of the module.

[0031] Preferably, a first housing and a second housing are provided in the box body. The first housing encloses a first cavity, and the second housing encloses a second cavity. Specifically, as Figure 1 shown, the first cavity and the second cavity are arranged at intervals along the width direction of the box body.

[0032] Furthermore, the second cavity has a mounting surface, and a first mounting position, a second mounting position, and a third mounting position are provided on the mounting surface. The electronic control module is arranged at the first mounting position, the power supply module is arranged at the second mounting position, and the high-voltage power distribution module is arranged at the third mounting position. The three mounting positions are laid flat on the mounting surface of the second cavity so that the main power supply module, the electronic control module, and the high-voltage power distribution module are arranged at intervals, that is, there is no mutual shielding and interference between the three modules, which is convenient for the independent maintenance and replacement of each module.

[0033] Specifically, as Figure 1 shown, the power supply module, the electronic control module, and the high-voltage power distribution module are arranged in sequence along the length direction of the second cavity, and there is no intersection and shielding in space between the modules. Among them, a low-voltage power supply interface, a communication interface, a direct charging interface, an AC charging interface, a motor interface, and a DC bus interface are provided on the box body. The low-voltage power supply interface, the direct charging interface, and the AC charging interface are all arranged close to the power supply module. The DC conversion control module is electrically connected to the low-power device through the direct charging interface to charge the low-power device. The AC charging control module is electrically connected to the high-voltage component through the AC charging interface to charge the high-voltage component (power battery). The motor interface is arranged close to the electronic control module, and the motor controller is electrically connected to the motor through the motor interface to control the speed and direction of the motor. The DC bus interface is arranged close to the high-voltage power distribution module, and the high-voltage power distribution module provides DC high-voltage power through the DC bus interface. Each module communicates with the corresponding device through the communication interface, such as sensor signal acquisition, control signal transmission, etc.

[0034] In another exemplary embodiment of the present application, the motor controller includes an electronic control board and a motor drive board. The control chips of the electronic control board, the control chips of the motor drive board, and the control chips of the first control board are integrated to form a first main control chip. That is, only the first main control chip is provided on the control board of the electronic control module. The first main control chip is used to control the electronic control board, the electronic control drive board, and the first control board. The number of chips in the electronic control module is reduced, and the internal layout of the electronic control module is more compact, which helps to reduce the volume and weight of the entire control system. In addition, the reduction in the number of chips in the electronic control module also reduces the low-voltage power consumption and development cost of the electronic control module.

[0035] Furthermore, the AC charging control module includes a second control board and a second power board. The control chips of the second control board form a second main control chip. That is, only the second main control chip is provided on the control board of the power supply module. The second main control chip is used to control the second control board and the second power board. The number of chips in the power supply module is reduced, and the internal layout of the power supply module is more compact, which helps to reduce the volume and weight of the entire control system. In addition, the reduction in the number of chips in the power supply module also reduces the low-voltage power consumption and development cost of the power supply module.

[0036] It should be noted that when integrating the control chips of the DC conversion control module and the AC charging control module, AC-DC isolation and high-low voltage isolation need to be considered. Therefore, the first control board of the DC conversion control module is integrated with the control chips of the electronic control module to reduce the number of chips in the entire control system and reduce the volume and weight of the entire control system.

[0037] In another exemplary embodiment of the present application, a heat dissipation component is provided in the box body. The heat dissipation component is used to dissipate heat from the electronic control module and the power supply module. The setting of the heat dissipation component effectively dissipates heat from the electronic control module and the power supply module to prevent the heat generated during operation from affecting their normal operation.

[0038] Specifically, the heat dissipation component includes a first water cooling pipe and a second water cooling pipe. The first water cooling pipe is provided on the power supply module, and the second water cooling pipe is provided on the electronic control module. Among them, both the first water cooling pipe and the second water cooling pipe are connected to the water inlet and outlet on the box body.

[0039] Exemplarily, the first water cooling pipe is coiled around the control board of the power supply module, and the second water cooling pipe is coiled around the control board of the electronic control module. The heat on the power supply module and the electronic control module is taken away by the circulating cooling water.

[0040] Furthermore, the first water cooling pipe and the second water cooling pipe are connected in series. The first water cooling pipe is connected to the water inlet, and the second water cooling pipe is connected to the water outlet. The two water cooling pipes are connected in series to reduce the number of water inlets and outlets and the number of pipeline connections, simplifying the system structure.

[0041] Specifically, during the operation of each module, the heat generated by the power module is less than that of the electronic control module. The first water-cooling pipe and the second water-cooling pipe are arranged in series, so that the cooling water passes through the power module and the electronic control module in sequence to achieve the best cooling effect.

[0042] According to another specific embodiment of the present application, a vehicle is provided, and the vehicle includes a control system, and the control system is the control system in the above embodiment.

[0043] Specifically, the control system includes a box body, an electronic control module, a power module, an electric drive module, and a high-voltage power distribution module. The box body has a receiving cavity. The electronic control module is arranged in the receiving cavity. The electronic control module includes a motor controller and a first control board of the DC conversion control module. The control chip of the motor controller and the control chip of the first control board are integrated to form a first main control chip. The power module is arranged in the receiving cavity. The power module includes an AC charging control module and a first power board of the DC conversion control module. The control chip of the AC charging control module forms a second main control chip. The electric drive module is arranged in the receiving cavity. The electric drive module includes a motor and a reducer. The high-voltage power distribution module is arranged in the receiving cavity, and the high-voltage power distribution module is electrically connected to the electronic control module and the power module respectively. By deeply integrating the control chips, the integration degree of the control system is improved, and the development cost and the overall weight of the control system are further reduced.

[0044] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0045] 1. The electronic control module, the power module, the electric drive module, and the high-voltage power distribution module are integrated in the same box body. Each module shares the box body, connectors, wiring harnesses, and cooling systems, saving the vehicle space and contributing to the development of the vehicle towards lightweight and miniaturization.

[0046] 2. The control chip of the motor controller in the electronic control module and the control chip of the first control board are deeply integrated, and the control chip of the AC charging control module in the power module is deeply integrated. By deeply integrating the control chips, the number of control chips is reduced, and then the number of compilers and debuggers corresponding to the control chips is reduced, reducing the development and maintenance costs, and at the same time reducing the low-voltage power consumption of the control chips.

[0047] 3. The control system adopts a modular design. After any module fails, it can be quickly repaired by replacing the faulty module alone.

[0048] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device.

Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.
