[0022] Combined with Figure 1 As shown, according to a specific embodiment of the present application, a control system for a vehicle is provided.

[0023] Specifically, the control system includes a box body, a main control module, a power supply module, a thermal management module, a high-voltage power distribution module, and an electric drive module. The box body has a receiving cavity. The main control module is disposed in the receiving cavity and includes a vehicle controller, a high-voltage battery management module, and a motor controller. The power supply module is disposed in the receiving cavity and includes a DC conversion control module, an AC charging control module, and a low-voltage battery control module. The thermal management module is disposed in the receiving cavity and includes an air-conditioning compressor control module, a heating control module, and an oil pump control module. The high-voltage power distribution module is disposed in the receiving cavity. The electric drive module is disposed in the receiving cavity and includes a motor and a reducer.

[0024] In an embodiment of the present application, twelve control modules of the vehicle, namely, the vehicle controller, the high-voltage battery management module, the motor controller, the DC conversion control module, the AC charging control module, the low-voltage battery control module, the air-conditioning compressor control module, the heating control module, the oil pump control module, the high-voltage power distribution module, the motor, and the reducer, are integrated in the same box body, reducing the external wiring of the controller, facilitating the overall layout of the control system, saving the space of the whole vehicle, and facilitating the lightweight and miniaturization of the vehicle; the twelve control modules are divided into five modules and then secondarily integrated, and multiple control modules can share a PCB board, further reducing the overall volume and manufacturing cost of the control system. In the above solution, multiple control modules of the vehicle are integrated into five control modules to reduce the volume and manufacturing cost of the control system, facilitate the space layout of the whole vehicle, and help reduce the cost and weight of the whole vehicle.

[0025] 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 is electrically connected to the main control module, the power supply module, and the thermal management module respectively, and is used to supply power to the main control module, the power supply module, and the thermal management module. Among them, the redundant power distribution of the main control module is provided by the power module, and the low-voltage battery control module in the power supply module is supplied with low voltage by an external device. The main control module is electrically connected to the electric drive module, and the high-voltage electricity in the main control module is inverted by an inverter and then supplied to the electric drive module.

[0026] It should be further noted that the box body is provided with an openable and closable box door for maintaining and disassembling and assembling each module in the box body.

[0027] 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 main control module, the power supply module, the thermal management module, and the high-voltage power distribution module are disposed in the second chamber.

[0028] Specifically, the motor and the reducer in the electric drive module are mechanical components, and the control modules in the main control module, the power supply module, the thermal management 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 layout is conducive to the maintenance and repair of the module.

[0029] Furthermore, the second chamber has a mounting surface, on which there are a first mounting position, a second mounting position, a third mounting position, and a fourth mounting position. The main control module is arranged at the first mounting position, the power supply module is arranged at the second mounting position, the thermal management module is arranged at the third mounting position, and the high-voltage power distribution module is arranged at the fourth mounting position. The four mounting positions are laid flat on the mounting surface of the second chamber, so that the main control module, the power supply module, the thermal management module, and the high-voltage power distribution module are spaced apart, that is, there is no mutual shielding and interference between the four modules, facilitating the independent maintenance and replacement of each module.

[0030] Specifically, as Figure 1 shown, the power supply module, the main control module, the thermal management module, and the high-voltage power distribution module are arranged in sequence along the length direction of the second chamber, and there is no intersection and shielding in space between the modules. Among them, the box body is provided with a low-voltage power supply interface, a communication interface, a direct charging interface, an AC charging interface, a motor interface, an air-conditioning compressor control module interface (ACP interface), an oil pump control module interface (EOP interface), and a DC bus interface. 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 low-voltage battery control module is electrically connected to an external low-voltage power supply device through the low-voltage power supply interface, and the DC conversion control module is electrically connected to a low-power device through the direct charging interface to charge the low-power device. The AC charging control module is electrically connected to a high-voltage component through the AC charging interface to charge the high-voltage component (power battery). The motor interface is arranged close to the main 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 air-conditioning compressor control module interface (ACP interface) and the oil pump control module interface (EOP interface) are both arranged close to the thermal management module. The air-conditioning compressor control module is connected to the air-conditioning compressor through the ACP interface to realize the refrigeration and heating of the air-conditioning system. 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.

[0031] In another exemplary embodiment of the present application, the control chips of the vehicle controller, the high-voltage battery management module, and the motor controller are integrated to form a first main control chip. The vehicle controller, the high-voltage battery management module, and the motor controller share the first control chip. Integrating the three control chips into one control chip not only reduces the volume of the main control module but also saves the manufacturing cost of the main control module.

[0032] Specifically, the first main control chip, as the core of the main control module, is responsible for processing the communication and data transmission between the various modules within the main control module to control the operating state of the vehicle. The vehicle controller obtains information such as the vehicle speed and steering through the first main control chip to control the vehicle's drive system; the high-voltage battery management module monitors information such as the battery state and temperature of the high-voltage battery through the first main control chip to achieve the management and protection of the battery; the motor controller controls the output power and speed of the motor through the first main control chip to achieve the control of the vehicle's power output. Further, the control chips of the DC conversion control module, the AC charging control module, and the low-voltage battery control module are integrated to form a second main control chip. The DC conversion control module, the AC charging control module, and the low-voltage battery control module share the second main control chip. Integrating the three control chips into one control chip not only reduces the volume of the power supply module but also saves the manufacturing cost of the power supply module.

[0033] Specifically, the DC conversion control module is responsible for converting high-voltage direct current into low-voltage direct current to charge low-power devices; the AC charging control module is responsible for monitoring the connection of the external AC power supply to achieve the charging control of high-voltage components; the low-voltage battery control module is responsible for monitoring parameters such as the voltage and temperature of the low-voltage battery to ensure the safe operation of the low-voltage battery. The second main control chip dynamically adjusts the output voltage of the DC conversion control module, the charging current of the AC charging control module, and the discharge current of the low-voltage battery control module according to the information fed back by the sensors of the various modules within the power supply module to achieve the efficient and safe operation of the system. At the same time, the second main control chip can also implement the fault diagnosis and protection functions of the system to ensure that the system can operate normally under various working conditions.

[0034] Further, the control chips of the air-conditioning compressor control module, the heating control module, and the oil pump control module are integrated to form a third main control chip. The air-conditioning compressor control module, the heating control module, and the oil pump control module share the third main control chip. Integrating the three control chips into one control chip not only reduces the volume of the thermal management module but also saves the manufacturing cost of the thermal management module.

[0035] Specifically, the air-conditioning compressor control module is a key component in the air-conditioning system, responsible for controlling the start-stop and operating status of the air-conditioning compressor to regulate the interior temperature of the vehicle. The heating control module is a module responsible for controlling the vehicle heating system, generally used in the heating systems of electric vehicles or hybrid vehicles. The heating control module adjusts the temperature of the thermistor (PTC) by controlling the current, thereby achieving heating of the vehicle interior. The heating control module has temperature-sensitive characteristics. When the temperature rises, the resistance value increases, thereby limiting the current and ensuring the safe operation of the heating system.

[0036] The oil pump control module is the control unit of the electric oil pump, responsible for controlling the operation of the electric oil pump. The oil pump control module controls the working state of the oil pump by receiving parameter signals such as motor speed and oil pressure, ensures the normal operation of the motor, and ensures that all components of the motor rotor are sufficiently lubricated. When the motor starts, the oil pump control module will start the oil pump to provide sufficient lubricating oil pressure to ensure the protection of all components of the motor during startup.

[0037] The third main control chip dynamically adjusts the working parameters of the air-conditioning compressor, heating module, and oil pump according to the information fed back by the sensors of each module in the thermal management module to achieve the efficient and safe operation of the system.

[0038] In another exemplary embodiment of the present application, a heat dissipation component is provided inside the box body, and the heat dissipation component is used to dissipate heat from the main control module, power supply module, and thermal management module.

[0039] A large amount of heat will be generated during the operation of the main control module, power supply module, and thermal management module. If the heat cannot be dissipated in a timely and effective manner, it will lead to too high a temperature, which will in turn affect the performance and stability of the equipment, and may even cause damage to the equipment.

[0040] Specifically, the heat dissipation component includes a first water-cooling pipe, a second water-cooling pipe, and a third water-cooling pipe. The first water-cooling pipe is provided on the power supply module, the second water-cooling pipe is provided on the main control module, and the third water-cooling pipe is provided on the thermal management module. Among them, the first water-cooling pipe, the second water-cooling pipe, and the third water-cooling pipe are all connected to the water inlet and outlet on the box body.

[0041] Exemplarily, the first water-cooling pipe is coiled around the control board of the power supply module, the second water-cooling pipe is coiled around the control board of the main control module, and the third water-cooling pipe is coiled around the control board of the thermal management module. The heat on the power supply module, main control module, and thermal management module is taken away by the circulating cooling water.

[0042] Further, the first water cooling pipe, the second water cooling pipe, and the third water cooling pipe are connected in series. The second water cooling pipe is located between the third water cooling pipes. The first water cooling pipe is connected to the water inlet, and the third water cooling pipe is connected to the water outlet. The three water cooling pipes are connected in series to reduce the number of water inlets and outlets, as well as the number of pipeline connections, and simplify the system structure.

[0043] Specifically, during the operation of each module, the heat generated by the power module is less than that of the main control module, and the heat generated by the main control module is less than that of the thermal management module. The first water cooling pipe, the second water cooling pipe, and the third water cooling pipe are connected in series in sequence, so that the cooling water passes through the power module, the main control module, and the thermal management module in sequence to achieve the best cooling effect.

[0044] According to another specific embodiment of the present application, a vehicle is provided. The vehicle includes a control system, and the control system is the control system in the above embodiment.

[0045] Specifically, the control system includes a box body, a main control module, a power module, a thermal management module, a high-voltage power distribution module, and an electric drive module. The box body has a receiving cavity, and one end of the receiving cavity is provided with an opening. The main control module is disposed in the receiving cavity, and the main control module includes a vehicle controller, a high-voltage battery management module, and a motor controller. The power module is disposed in the receiving cavity, and the power module includes a DC conversion control module, an AC charging control module, and a low-voltage battery control module. The thermal management module is disposed in the receiving cavity, and the thermal management module includes an air-conditioning compressor control module, a heating control module, and an oil pump control module. The high-voltage power distribution module is disposed in the receiving cavity, and the high-voltage power distribution module includes a high-voltage filtering module, a distribution copper bar, a fuse, and a fuse replacement cover plate. The electric drive module is disposed in the receiving cavity, and the electric drive module includes a motor and a reducer. The control system includes 12 control modules, which are divided into five modules and integrated in the same box body to reduce the volume and manufacturing cost of the control system, facilitate the space layout of the whole vehicle, and help reduce the cost and weight of the whole vehicle.
