[0001] (Cross - reference to related applications) This disclosure claims the priority of Chinese Patent Application No. 202110889134.3, titled "Integrated Controller, Electric Drive Assembly and Vehicle", filed with the China National Intellectual Property Administration on August 4, 2021, and all of its contents are incorporated herein by reference.

[0002] This disclosure relates to the technical field of vehicles, and in particular, to an integrated controller, an electric drive assembly and a vehicle.

Background Art

[0003] In related technologies, the electric drive assembly has multiple integration methods, such as the 2 - in - 1 integration of a motor controller and a DC / DC, or the 3 - in - 1 integration of a motor, a motor controller and a reducer, or the 3 - in - 1 integration of a DC / DC, an OBC (ON - Board Controller) and a PDU (Power Distribution Unit), etc., thereby reducing costs such as wire harness and support. However, all of the above integrations are physical integration means, only assembling different modules, and there is little reuse of elements between components.

[0004] For example, taking the "Power 3 - in - 1" integration method of a motor, a motor controller and a reducer as an example, the signal wire harness between the integrated "Power 3 - in - 1" and the VCU (Vehicle Control Unit), the high - voltage wire harness between the integrated "Power 3 - in - 1" and the PDU, the high - voltage wire harness between the PDU and the DC / DC and the OBC, the signal wire harness for the interaction between the DC, the OBC and the complete vehicle, etc., as well as the cases of these modules and module fixing supports are all necessary, resulting in high costs. When the modules are arranged individually, the occupied space in the complete vehicle is large and the transmission speed of signal interaction is slow.

Modes for Carrying Out the Invention

[0024] Hereinafter, embodiments of the present disclosure will be described in detail. The embodiments described with reference to the drawings are exemplary, and the embodiments of the present disclosure will be described in detail.

[0025] To solve the above problems, an embodiment of the first aspect of the present disclosure provides an integrated controller, which does not require the installation of a high-voltage power distribution box, can reduce the demand for high-voltage wire harnesses, reduce costs, and save space in the finished vehicle.

[0026] Hereinafter, the integrated controller according to the embodiment of the present disclosure will be described with reference to FIGS. 1 to 4.

[0027] As shown in FIG. 1, the integrated controller 10 includes a housing 1, a control unit 2, a charge and discharge conversion unit 3, and a high-voltage interface component 4.

[0028] The control unit 2 and the charge and discharge conversion unit 3 are installed in the housing 1. That is, by using the same housing 1 for the control unit 2 and the charge and discharge conversion unit 3, the use of cases can be reduced structurally, the integration degree can be improved, the occupied space can be saved, and the cost can be reduced.

[0029] The high-voltage interface component 4 includes a high-voltage interface installed on the housing 1 and a high-voltage connection member installed inside the housing 1. The high-voltage connection member is connected to the high-voltage interface, the control unit 2, and the charge and discharge conversion unit 3, and receives and distributes high-voltage battery signals. Specifically, in the high-voltage power distribution design of a conventional complete vehicle, there is a high-voltage power distribution box, and the high-voltage power needs to be input into the high-voltage power distribution box through the high-voltage interface. The high-voltage power distribution box divides the high-voltage power into multiple branches, and each branch passes through different fuses and contacts and is then output through different high-voltage interfaces to complete the high-voltage power distribution to other modules outside the high-voltage power distribution box. Different from the high-voltage power distribution design of a conventional complete vehicle, in the embodiments of the present disclosure, the high-voltage interface component 4 is installed, the control unit 2 and the charge and discharge conversion unit 3 are installed inside the housing 1, and both are connected to the high-voltage connection member installed inside the housing 1. In this way, the high-voltage wire harness connected to the control unit 2 and the charge and discharge conversion unit 3 shares the same housing 1 with the control unit 2 and the charge and discharge conversion unit 3. That is, in the embodiments of the present disclosure, the high-voltage connection member, which is the part that distributes the high-voltage power in the high-voltage power distribution box in the high-voltage power distribution design of a conventional complete vehicle, and the parts of the control unit 2 and the charge and discharge conversion unit 3, which are other modules outside the high-voltage power distribution box, are newly combined and integrally arranged inside the housing 1. With such a design, there is no need to install a high-voltage power distribution box, which not only saves space, but also eliminates the need to design corresponding high-voltage interfaces for high-voltage power distribution to the control unit 2 and the charge and discharge conversion unit 3, reduces the demand for high-voltage connectors and high-voltage wire harnesses, and can reduce costs.

[0030] In an embodiment of the present disclosure, the integrated controller 10 according to the embodiment is arranged such that the control unit 2 and the charge and discharge conversion unit 3 use the same housing 1, thereby reducing the use of structural members, reducing costs, and arranging the high-voltage interface component 4 to be connected to the control unit 2 and the charge and discharge conversion unit 3, thereby reducing the demand for high-voltage connectors and high-voltage wire harnesses, eliminating the need to install a high-voltage power distribution box, saving space, and reducing costs.

[0031] In some embodiments, the control unit 2 includes a motor controller, a complete vehicle controller, and a battery management controller. That is, by highly integrating the motor controller, the complete vehicle controller, and the battery management controller, not only can the volume of the assembly be reduced and the demand for signal wire harnesses be reduced, but also the interaction time can be shortened and the efficiency can be improved. And the charge and discharge conversion unit 3 includes a DC conversion unit and an in-vehicle charging unit. That is, by integrating the DC conversion unit and the in-vehicle charging unit, the volume of the assembly can be reduced and the integration degree can be improved. Thereby, the above integration method is also advantageous for the subsequent reuse of structures or modules, and improves the reuse degree of the integrated controller 10.

[0032] In some embodiments, as shown in FIG. 1, the high-voltage interface component 4 includes a first high-voltage interface 41, a second high-voltage interface 42, and a third high-voltage interface 43 installed on the housing, and a first connection member, a second connection member, a third connection member, and a fourth connection member.

[0033] The first high-voltage interface 41 receives a high-voltage battery signal. The first connection member is connected to the first high-voltage interface 41 and the second high-voltage interface 42 respectively. The second connection member is connected to the DC conversion unit and the in-vehicle charging unit. The third connection member is connected to the motor controller. The fourth connection member is connected to the first high-voltage interface 41 and the third high-voltage interface 43.

[0034] Specifically, different from the conventional high-voltage power supply distribution design of a complete vehicle, in the embodiments of the present disclosure, the related components in the conventional high-voltage power supply distribution box are divided into two parts. As shown in FIG. 1, one part of the high-voltage power supply distribution box is installed in the high-voltage battery of the complete vehicle and connected to the power battery, and the other part is connected to the control unit 2 and the charge and discharge conversion unit 3 and arranged in the housing 1. Thereby, when high-voltage power is distributed, the high-voltage battery signal, which is a high-voltage power source, is output through the fuse K1 and the high-voltage interface at the high-voltage battery end, and is transmitted to the first high-voltage interface 41 by the connected high-voltage wire harness. The first high-voltage interface 41 divides the high-voltage battery signal into four parts, that is, distributes the high-voltage power supply to the motor controller of the control unit 2, distributes the high-voltage power supply to the DC conversion unit and the in-vehicle charging unit in the housing 1 through the fuse K3, outputs it to the second high-voltage interface 42 through the fuse K2, and distributes the high-voltage power supply to the air conditioner outside the housing 1 through the high-voltage wire harness via the high-voltage interface on the air conditioner side, and controls the output to the third high-voltage interface 43 by the positive and negative contactors to distribute the power to the DC charging port outside the housing 1. Thereby, the embodiments of the present disclosure not only do not need to install a high-voltage power supply distribution box due to the above integrated design of multiple in1, but also reduce the use of high-voltage interfaces and high-voltage wire harnesses for distributing high-voltage current to the control unit 2 and the charge and discharge conversion unit 3, shorten the length of the wire harness between different modules, reduce costs, and save space.

[0035] In some embodiments, as shown in FIG. 2, the integrated controller 10 further includes a low-voltage connector 5.

[0036] The low-voltage connector 5 is installed in the housing 1, connected to the control unit 2 and the charge and discharge conversion unit 3, and receives low-voltage power signals and transmission communication signals. Specifically, in the low-voltage design of conventional production vehicles, since each module is equipped with an independent controller, it is necessary to individually install a low-voltage connector for each module to interact with external signals. However, in the embodiments of the present disclosure, all the low-voltage connectors in the low-voltage design of conventional production vehicles are integrated into one, that is, after integrating the motor controller, the production vehicle controller, and the battery management controller into the control unit 2, and integrating the DC conversion unit and the in-vehicle charging unit into the charge and discharge conversion unit 3, the control unit 2 and the charge and discharge conversion unit 3 use the same low-voltage connector 5. After the low-voltage power signal and the transmission communication signal are input by the low-voltage connector 5, they are split into two, and power supply and two-way signal communication are respectively performed for the control unit 2 and the charge and discharge conversion unit 3. Designed in this way, the use of low-voltage wire harnesses and low-voltage interfaces can be reduced, and costs can be reduced.

[0037] In some embodiments, as shown in FIG. 3, the motor controller, the production vehicle controller, and the battery management controller are integrated into the first digital signal processing chip 11, the DC conversion unit is installed in the second digital signal processing chip 12, and the in-vehicle charging unit is installed in the third digital signal processing chip 13.

[0038] That is, in the low-voltage design of conventional production vehicles, a separate digital signal processing chip is correspondingly installed for each module to collect and control signals. However, in the embodiments of the present disclosure, after integrating the motor controller, the production vehicle controller, and the battery management controller into the control unit 2, and integrating the DC conversion unit and the in-vehicle charging unit into the charge and discharge conversion unit 3, when resources are sufficient, by designing to integrate and use the motor controller, the production vehicle controller, and the battery management controller in the first digital signal processing chip 11, the number of digital signal processing chips used can be reduced, costs can be reduced, and the occupied space can be reduced.

[0039] Specifically, as shown in FIG. 2, in the embodiments of the present disclosure, all low-voltage connectors in the low-voltage design of a conventional finished vehicle are integrated, and both the low-voltage power signal and the transmission communication signal transmitted to the control unit 2 and the charge and discharge conversion unit 3 are input through the interface of the same low-voltage connector 5, so that the number of low-voltage connectors used can be reduced. On the premise that the received low-voltage power signal and the transmission communication signal are the same, different modules in the control unit 2 and the charge and discharge conversion unit 3 can share the same interface pin for input. That is, the embodiments of the present disclosure change the conventional method in which different modules collect the required communication signals respectively to a method in which the same sampling channel is used for the same communication signal among different modules. That is, the same communication signal is transmitted by the same pin of the low-voltage connector 5 and transmitted to different modules, so that the number of pins of the low-voltage connector 5 can be reduced and the cost can be reduced.

[0040] In an embodiment, as shown in FIG. 3, for the same transmission communication signal transmitted from the outside, the low-voltage connector 5 only designs one sampling channel for signal collection, and transmits the collected signal for information processing to different digital signal processing chips. For example, for the power grid CAN communication, a fixed connector for external connection is installed on the low-voltage connector 5, that is, the power grid CAN communication signal is received only by this connector. The low-voltage connector 5 divides the received power grid CAN communication signal into three parts, and transmits them to the first digital signal processing chip 11, the second digital signal processing chip 12, and the third digital signal processing chip 13 respectively, so that the complete vehicle controller, the DC conversion unit, and the in-vehicle charging unit can simultaneously receive the power grid CAN communication signal. For the AC charging CC signal, this signal is a collection signal required by both the in-vehicle charging unit and the battery management controller. After integration, for the transmission of this signal, it is integrated into one connector interface and one collection channel is used, that is, this signal is input using only one channel of the low-voltage connector 5 and is divided into two parts and transmitted to the in-vehicle charging unit and the battery management controller respectively. Thus, the battery management controller and the in-vehicle charging unit can execute corresponding operations based on this signal. For example, detect the state information of whether the charging gun is connected. For the collision signal, the bus voltage sampling signal, or the water temperature sampling signal, this signal needs to be transmitted to the motor controller, the complete vehicle controller, and the battery management controller individually before integration. However, after integrating the motor controller, the complete vehicle controller, and the battery management controller into the first digital signal processing chip 11, the transmission of this signal can be integrated and the interface of the same low-voltage connector 5 can be used, and it can be transmitted to the integrated first digital signal processing chip 11 using one collection channel. Thereby, the complete vehicle controller can know whether the complete vehicle has collided based on the collision signal, obtain the voltage value of the power battery based on the bus voltage sampling signal, and know the heat dissipation situation of the heat dissipation system and the control of the water pump based on the water temperature sampling signal, etc.Therefore, different from the design in the conventional complete vehicle where each module uses separate components, in the embodiments of the present disclosure, by reusing the low-voltage connector 5 and the low-voltage interface, the objectives of low cost, small volume, and light weight are achieved.

[0041] In some embodiments, as shown in FIG. 2, the integrated controller 10 further includes a first power supply unit 6 and a second power supply unit 7.

[0042] The first power supply unit 6 is connected to the first digital signal processing chip 11 and converts a low-voltage power signal into a Supplied power supply signal for the first digital signal processing chip 11. The second power supply unit 7 is connected to the second digital signal processing chip 12 and the third digital signal processing chip 13 and converts a low-voltage power signal into the necessary power supply signals for the second digital signal processing chip 12 and the third digital signal processing chip 13.

[0043] That is, different from the design in the conventional complete vehicle where each module is provided with a separate power supply, as shown in FIG. 2, in the embodiments of the present disclosure, after integrating the motor controller, the complete vehicle controller, and the battery management controller into the control unit 2, and integrating the DC conversion unit and the in-vehicle charging unit into the charge and discharge conversion unit 3, the conventional method of individually supplying power to each of different modules is changed to a method of reusing the same voltage power supply in multiple modules. Specifically, the low-voltage power signals are all received from the low-voltage connector 5, split into two, and transmitted to the first power supply unit 6 and the second power supply unit 7 respectively. The first power supply unit 6 converts the low-voltage power signal into a of power supply for the control unit 2. The second power supply unit 7 converts the low-voltage power signal into the necessary power supply signals for the second digital signal processing chip 12 and the third digital signal processing chip 13 ofConvert it into power and supply power to the charge and discharge conversion unit 3. Thereby, in the embodiments of the present disclosure, by integrating a plurality of power supply modules in the conventional complete vehicle design into the first power supply unit 6 and the second power supply unit 7, the demand for structural members of the power supply module can be reduced, the cost can be reduced, the volume can be reduced, and the space of the complete vehicle can be saved.

[0044] In some embodiments, as shown in FIG. 2 or FIG. 4, the integrated controller 10 further includes an inlet filter unit 8.

[0045] The inlet filter unit 8 is connected to the low-voltage connector 5, the first power supply unit 6, and the second power supply unit 7, and performs filter processing on the low-voltage power supply signal.

[0046] Specifically, in the low-voltage design of the conventional complete vehicle, each module is provided with a separate inlet filter protection circuit. However, in the embodiments of the present disclosure, a plurality of inlet filter protection circuits in the conventional complete vehicle design are integrated into one inlet filter unit 8, that is, each module in the integrated controller 10 shares the same inlet filter unit 8. For example, as shown in FIG. 4, the low-voltage battery power supply of the passenger car is 12V, and all modules in the complete vehicle receive power from a 12V power supply. The low-voltage power supply signal is input through the low-voltage connector 5 and uniformly input to the inlet filter unit 8. The inlet filter unit 8 performs circuit processing such as inlet protection filter processing, for example, inlet TVS tube, reverse current prevention diode, inlet electrolytic capacitor, inlet ceramic capacitor, magnetic bead, differential mode inductor, common mode inductor, etc. on the low-voltage power supply signal, and transmits the processed low-voltage power supply signal to the first power supply unit 6 and the second power supply unit 7 to supply low-voltage power to different modules in the integrated controller 10. Thereby, with the above design, not only can situations such as inlet interference, lightning strike, and surge be effectively avoided, but also the design of the inlet filter protection circuit can be reduced, the cost can be reduced, and the space can be saved.

[0047] In short, the integrated controller 10 according to the embodiments of the present disclosure integrates the motor controller, the complete vehicle controller, and the battery management controller into the control unit 2, and integrates the DC conversion unit and the in-vehicle charging unit into the charge and discharge conversion unit 3, so that there is no need to install a high-voltage power distribution box, which not only reduces the demand for high-voltage connectors and high-voltage wire harnesses, but also can reduce the design of the module case and related support frames by sharing the same housing 1. In addition, by sharing the low-voltage connector 5, the low-voltage wire harness and the low-voltage interface can be saved. Furthermore, the power supply unit and the collection channel can be reused between different modules that use the same power supply and collect the same signal, eliminating the need to design the power supply module and the signal wire harness separately, thereby reducing the cost of the complete vehicle, saving the space of the complete vehicle, reducing the weight of the complete vehicle, and improving the integration degree and reusability of the complete vehicle.

[0048] An embodiment of the second aspect of the present disclosure provides an electric drive assembly. As shown in FIG. 5, the electric drive assembly 20 includes the integrated controller 20 according to the above embodiment, a motor 301, and a motor drive module 302.

[0049] When the integrated controller 20 determines that heating is required for the vehicle, it sends a heating control signal. The motor drive module 302 is connected to the integrated controller 20 and the motor 301, and drives the motor in response to the heating control signal to generate heat. That is, in the embodiments of the present disclosure, by using the integrated controller 10 after integration in the above embodiments and sharing the motor 301 and the motor drive module 302 for each module in the integrated controller 10, the function of heating the battery in a low-temperature environment is realized, eliminating the need to design a heating module for heating the battery, and further reducing the cost of the complete vehicle.

[0050] Specifically, as shown in FIG. 5, in the embodiment of the present disclosure, in order to heat the high-voltage battery, the integrated controller 10 and the motor drive module 302 of the electric drive assembly 20 are directly reused. The integrated controller 10 outputs a certain proportion of reactive current or Lock rotor heating in outputs all the reactive current to heat the motor drive module 302 and the motor winding, thereby raising the water temperature in a low-temperature environment and heating the high-voltage battery by the water circulation system of the complete vehicle.

[0051] As shown in FIG. 5, the electric drive assembly 20 is mainly divided into the following three operating states.

[0052] The electric drive assembly 20 is in the normal drive mode. The integrated controller 10 can drive the vehicle to run normally by ensuring that the output torque at the shaft end is maximum by outputting id = 0 and iq = Imax during software control. In a low-temperature environment, in order to ensure that the performance of the battery can be well exerted, it is necessary to heat the battery, that is, reuse the motor drive module 302 to heat the battery, generate heat by the motor 301, heat the battery by the heat circulation system. The heating by the motor drive module 302 is divided into two modes: driving heating and restraint heating. The driving heating is usually performed at medium and low torques. The integrated controller 10 controls to increase id and decrease iq to ensure that the output torque at the shaft end remains unchanged, and increases the total current to achieve heating. Lock rotor The heating is for the case of parking. The integrated controller 10 controls id = Imax and iq = 0 to ensure that the output torque at the shaft end is 0, and heats the motor by the three-phase DC heating method.

[0053] The electric drive assembly 20 according to an embodiment of the present disclosure can control the motor drive module 302 using a motor controller by an integrated controller 10, and can realize the function of heating the battery in a low-temperature environment by using the methods of traveling heating and restraint heating, without the need to design a heating module for heating the battery, thereby reducing the cost of the complete vehicle.

[0054] In some embodiments, the electric drive assembly 20 further includes a speed reducer, and the speed reducer is connected to the integrated controller 10, that is, structurally, for different modules in the integrated controller 10, the same motor 301 and speed reducer are used, and by structurally reusing, the use of structural members can be reduced, the cost of the complete vehicle can be reduced, the volume of the assembly can be reduced, and the weight can be reduced.

[0055] An embodiment of the third aspect of the present disclosure provides a vehicle, and hereinafter, the vehicle according to the embodiment of the present disclosure will be described.

[0056] In an embodiment of the present disclosure, the vehicle 30 includes a power battery 301 and the integrated controller 10 according to the above embodiment, and the power battery 301 is connected to the integrated controller 10.

[0057] In this embodiment, the specific implementation manner of the vehicle 30 is similar to the specific implementation manner of the integrated controller 10 according to any of the above embodiments of the present disclosure. Specifically, refer to the description of the part of the integrated controller 10, and for the sake of reducing redundancy, the description is omitted here.

[0058] In another embodiment of the present disclosure, as shown in FIG. 6, the vehicle 30 includes a power battery 301 and the electric drive assembly 20 according to the above embodiment.

[0059] In the embodiment, the AC charging port realizes a bidirectional conversion function of converting 220V AC to DC or DC to AC through a PFC (Power Factor Correction) circuit. Then, by sharing the primary side of the transformer of the on-vehicle charging unit and adding one winding to the secondary side, the output function of the DC conversion unit can be realized simultaneously.

[0060] The charging methods for the vehicle 30 are divided into DC charging and AC charging. During DC charging, the current flows from the charging stand through the power distribution unit of the electric drive assembly 20 to the power battery 301 to charge the power battery 301. During AC charging, the current is converted by the on-vehicle charging unit in the electric drive assembly 20 from 220V household power to charge the power battery 301. When driving the vehicle 30 to run normally, the current flows from the power battery 301 through the motor controller in the electric drive assembly 20 to the motor to drive the vehicle 30 to run normally. Heating is divided into driving heating and restraint heating. Driving heating means that during the process of normal driving of the vehicle 30, the motor controller controls through PWM waves so that part of the current outputs useful work to drive the vehicle 30 to run, and the other part of the current outputs ineffective work, and the current flows through the motor controller and the motor, and the motor coil generates heat to heat the coolant, and finally heats the power battery 301.

[0061] By using the integrated controller 10 or the electric drive assembly 20 according to the above embodiment, the vehicle 30 according to the embodiment of the present disclosure can improve the integration degree and reusability of the complete vehicle, reduce the cost of the complete vehicle, and save the space of the complete vehicle.
