TECHNICAL FIELD

[0001] The application belongs to the technical field of intelligent control, and particularly relates to a control device, an intelligent device and a method. BACKGROUND

[0002] With the development of science and technology, intelligent devices are more and more favored by people, such as driving devices, vehicles, robots and the like. In the intelligent devices, an air compressor system and a charger system are two key core systems. The air compressor system provides compressed air for the intelligent device, so that the brake system, the air conditioning system and other devices requiring compressed air assistance can normally operate. The charger system can convert external input alternating current into direct current suitable for charging the power battery, so as to charge the power battery.

[0003] However, in the traditional technology, the air compressor system and the charger system are two independent systems. The air compressor system has a plurality of components required for its own operation, and the charger system also has a plurality of components required for its own operation, which are independently operated with each other, so that the two systems occupy a large amount of space, thereby causing the overall system to be relatively large in size. SUMMARY

[0004] The application aims to provide a control device and a method, and aims to solve the problem of the relatively large size of the overall system in the traditional technology.

[0005] The application provides a control device, comprising:

[0006] An air compressor motor is connected with one end of an alternating current power supply module, the air compressor motor is used to operate in the case that the alternating current power supply module provides alternating current, and the air compressor motor is also used to store and release the alternating current;

[0007] An electric energy conversion module is connected with the air compressor motor and the other end of the alternating current power supply module, and is used to convert the alternating current into direct current;

[0008] A high-voltage energy storage module is connected with the electric energy conversion module, and is used to store the direct current converted by the electric energy conversion module.

[0009] The application provides an intelligent device, comprising the control device in any one of the above embodiments.

[0010] The application provides a control method, comprising:

[0011] Obtaining a device state of an intelligent device;

[0012] If the device state is a stop state, the alternating current power supply module is controlled to provide alternating current to the air compressor motor, and the electric energy conversion module is controlled to convert the alternating current into direct current, and transmit the direct current to the high-voltage energy storage module to charge the high-voltage energy storage module.

[0013] Compared with the prior art, the embodiment of the present application has the following beneficial effects:

[0014] The air compressor motor is the core power component of the air compressor system. The air compressor motor runs through the alternating current provided by the external alternating current power supply module, converts the electric energy into mechanical energy, drives the air compressor to compress air, and realizes the function of the air compressor system.

[0015] When the air compressor motor is connected to one end of the alternating current power supply module, the winding of the air compressor motor can also act as an inductor coil, playing a role in energy storage and release. Further, the air compressor motor can store the alternating current energy provided by the alternating current power supply module in the form of magnetic field energy. The electric energy conversion module is connected to the air compressor motor, which can release the magnetic field energy stored in the air compressor motor and transmit it to the high-voltage energy storage module, realizing charging of the high-voltage energy storage module. The energy of the alternating current power supply module flows to the air compressor motor, driving the air compressor motor to run, so that the vehicle is in the air compressor working mode, realizing the function of the air compressor system. The energy of the alternating current power supply module flows to the high-voltage energy storage module through the air compressor motor and the electric energy conversion module, charging the high-voltage energy storage module, so that the vehicle is in the vehicle charger working mode, realizing the function of the charger system.

[0016] Therefore, the air compressor motor serves as a common component of the air compressor system and the charger system, reducing the number of components required for the operation of the traditional air compressor system and the traditional charger system, saving the occupied space, and reducing the overall system volume. Through the control device provided by the present application, the alternating current power supply module can be charged to the high-voltage energy storage module when the air compressor motor is running, realizing the air compressor working mode and the vehicle charger working mode.

[0017] Further, the air compressor motor serves as a common component of the air compressor system and the charger system, reducing the number of components required for the operation of the traditional air compressor system and the traditional charger system, reducing the cost and weight, and improving the integration of the overall vehicle system.

[0033] Please refer to Figure 1 The application provides a control device 100. The control device 100 includes an air compressor motor 10, an electric energy conversion module 20, and a high-voltage energy storage module 40. The air compressor motor 10 is used to be connected with one end of an alternating current power supply module 30. The air compressor motor 10 is used to operate in the case that the alternating current power supply module 30 provides alternating current. The electric energy conversion module 20 is connected with the air compressor motor 10 and the other end of the alternating current power supply module 30, and is used to convert alternating current into direct current. The high-voltage energy storage module 40 is connected with the electric energy conversion module 20, and is used to store the direct current converted by the electric energy conversion module 20.

[0034] In the embodiment, the air compressor motor 10 is the core power component of the air compressor system. The air compressor motor 10 operates through the alternating current provided by the external alternating current power supply module 30, converts electric energy into mechanical energy, drives the air compressor to compress air, so as to realize the function of the air compressor system.

[0035] When the air compressor motor 10 is connected to one end of the AC power supply module 30, the winding of the air compressor motor 10 can also act as an inductive coil, playing a role in energy storage and release. The electric energy conversion module 20 is connected to the air compressor motor 10 and the other end of the AC power supply module 30, and can convert the electric energy provided by the AC power supply module 30 into the electric energy required by the high-voltage energy storage module 40. Through the electric energy conversion module 20, the air compressor motor 10 stores the AC electric energy provided by the AC power supply module 30 in the form of magnetic field energy, and can release the magnetic field energy stored in the air compressor motor 10 and transmit it to the high-voltage energy storage module 40, realizing the charging of the high-voltage energy storage module 40. The energy of the AC power supply module 30 flows to the air compressor motor 10, driving the air compressor motor 10 to operate, so that the vehicle is in the air compressor working mode, realizing the function of the air compressor system. The energy of the AC power supply module 30 flows to the high-voltage energy storage module 40 through the air compressor motor 10 and the electric energy conversion module 20, charging the high-voltage energy storage module 40, so that the vehicle is in the on-board charger working mode, realizing the function of the charger system.

[0036] Therefore, the air compressor motor 10 serves as a common component of the air compressor system and the charger system, reducing the number of components required for the operation of the traditional air compressor system and the traditional charger system, saving the occupied space, and reducing the overall system volume. Through the control device 100 provided in the present application, the air compressor motor 10 can realize the charging of the high-voltage energy storage module 40 by the AC power supply module 30 when the air compressor motor 10 operates, realizing the air compressor working mode and the on-board charger working mode.

[0037] Further, the air compressor motor 10 serves as a common component of the air compressor system and the charger system, reducing the number of components required for the operation of the traditional air compressor system and the traditional charger system, reducing the cost and weight, and improving the integration of the overall vehicle system.

[0038] In one embodiment, the control device 100 is applied to a vehicle. The vehicle can include a smart electric vehicle or a hybrid vehicle, etc. The vehicle includes but is not limited to a car, a truck, a bus, an electric vehicle, a motorcycle, a motor home, a train, etc. The vehicle can be a vehicle driven by a person. In some other embodiments, the vehicle can also be a vehicle with a certain automatic driving capability. The charger system is an on-board charger (OBC) system.

[0039] In one embodiment, the AC power supply module 30 can be a charging facility outside the vehicle, such as a household socket or a public charging pile, etc. which can provide single-phase AC power, used to provide AC input.

[0040] Please refer to Figure 2 With Figure 3In one embodiment, the power conversion module 20 comprises at least one first power circuit 210 and a second power circuit 220. The first power circuit 210 is connected to the air compressor motor 10, and is used to adjust the power conversion during the charging process of the AC power supply module 30 to the high-voltage energy storage module 40.

[0041] The second power circuit 220 is connected to the first power circuit 210 and the other end of the AC power supply module 30, and is used to buffer the energy flow during the charging process of the AC power supply module 30 to the high-voltage energy storage module 40. The common connection end of the first power circuit 210 and the second power circuit 220 is used to connect to the high-voltage energy storage module 40.

[0042] In this embodiment, the first power circuit 210 is connected to the air compressor motor 10. The air compressor motor 10 acts as an inductor coil, which plays a role in energy storage and release. Through the first power circuit 210, energy conversion and transmission can be carried out, so that the current waveform follows the change of the voltage waveform, thereby improving the power factor and adjusting the power conversion during the charging process of the AC power supply module 30 to the high-voltage energy storage module 40.

[0043] The second power circuit 220 works with the first power circuit 210 to assist the first power circuit 210, which can buffer the energy in the circuit and slowly adjust the energy flow to avoid problems such as voltage spikes or current surges caused by rapid changes in inductor coil energy, to ensure more stable power conversion.

[0044] Further, through at least one first power circuit 210 and a second power circuit 220, the electrical energy provided by the AC power supply module 30 can be converted into the electrical energy required by the high-voltage energy storage module 40, realizing the charging of the AC power supply module 30 to the high-voltage energy storage module 40. Thus, the air compressor motor 10 as a common component of the air compressor system and the charger system can make the air compressor motor 10 run and realize the charging of the AC power supply module 30 to the high-voltage energy storage module 40, realizing the air compressor working mode and the vehicle-mounted charger working mode, so that the overall vehicle system is deeply integrated.

[0045] In one embodiment, the second power circuit 220 can be applied to the driving circuit for driving the electric motor 50 to operate. The second power circuit 220 can also be separately provided and cooperates with the first power circuit 210 to realize the charging of the high-voltage energy storage module 40, as shown in Figure 3 The number of second power circuits 220 can also be adjusted according to actual conditions.

[0046] In one embodiment, the control device 100 comprises two second power circuits 220, one of which is applied to the driving circuit for driving the electric drive motor 50 to operate, and the other of which works with the first power circuit 210 to charge the high-voltage energy storage module 40.

[0047] In one embodiment, the number of first power circuits 210 can be set according to actual conditions. The number of first power circuits 210 can be one, two, or three, etc. When the air compressor motor 10 is a three-phase motor, three winding coils are respectively connected to three first power circuits 210 to work cooperatively.

[0048] Please refer to Figure 4 In one embodiment, the first power circuit 210 is also used to drive the air compressor motor 10 to operate according to the direct current provided by the high-voltage energy storage module 40.

[0049] In this embodiment, the high-voltage energy storage module 40 provides the electric energy required for the air compressor motor 10 to operate. The high-voltage energy storage module 40, at least one first power circuit 210, and the air compressor motor 10 form an energy flow link, which can drive the air compressor motor 10 to operate. The first power circuit 210 can convert the direct current provided by the high-voltage energy storage module 40 into alternating current required by the air compressor motor 10 to drive the air compressor motor 10 to operate.

[0050] The high-voltage energy storage module 40, at least one first power circuit 210, and the air compressor motor 10 form a first air compressor driving link. The alternating current power supply module 30 and the air compressor motor 10 form a second air compressor driving link. The alternating current power supply module 30, the air compressor motor 10, at least one first power circuit 210, the second power circuit 220, and the high-voltage energy storage module 40 form a charging link. Further, the first air compressor driving link, the second air compressor driving link, and the charging link can share at least one first power circuit 210 and the air compressor motor 10, realizing the mutual integration of the three different links, reducing the number of components required for the traditional system to operate, saving the occupied space, reducing the overall system volume, and realizing the air compressor working mode and the vehicle-mounted charger working mode.

[0051] Further, the control device 100 provided by the present application reduces the number of components required for the traditional system to operate, reduces the overall cost and weight, and improves the integration of the overall vehicle system.

[0052] In one embodiment, the first power circuit 210 is used to drive the air compressor motor 10 to operate according to the direct current provided by the high-voltage energy storage module 40 when the alternating current power supply module 30 does not charge the high-voltage energy storage module 40.

[0053] In the embodiment, when the AC power supply module 30 does not charge the high-voltage energy storage module 40, the connection link between the AC power supply module 30 and the air compressor motor 10 is disconnected, and thus the AC power supply module 30 does not supply power to the air compressor motor 10. The air compressor motor 10 runs by the power provided by the high-voltage energy storage module 40.

[0054] In one embodiment, the three first power circuits 210 are respectively connected to the three-phase windings of the air compressor motor 10, forming a three-phase control circuit corresponding to the U-phase, V-phase and W-phase of the three-phase power. Thus, a regularly changing current is generated in the three-phase windings of the air compressor motor 10, thereby forming a rotating magnetic field to drive the air compressor motor 10 to run.

[0055] In one embodiment, when the AC power supply module 30 does not charge the high-voltage energy storage module 40, the vehicle is in a driving state or a stopped state. Regardless of whether the vehicle is in a driving state or a stopped state, the control device 100 provided by the present application can realize the air compressor working mode, ensuring the normal operation of the air compressor system in the vehicle.

[0056] Please refer to Figure 4 In one embodiment, the second power circuit 220 is further configured to drive the electric drive motor 50 to run according to the direct current provided by the high-voltage energy storage module 40.

The electric drive motor system can convert electrical energy into mechanical energy to drive the vehicle to run, and realize acceleration, deceleration and cruising of the vehicle.

[0058] The electric drive motor 50 runs by the power provided by the high-voltage energy storage module 40. The high-voltage energy storage module 40, the second power circuit 220 and the electric drive motor 50 form an energy flow link, which can drive the electric drive motor 50 to run. The second power circuit 220 can convert the direct current provided by the high-voltage energy storage module 40 into alternating current required by the electric drive motor 50, so as to drive the electric drive motor 50 to run.

[0059] The high-voltage energy storage module 40, the second power circuit 220, and the electric drive motor 50 form an electric drive motor driving link. The AC power supply module 30, the air compressor motor 10, the first power circuit 210, the second power circuit 220, and the high-voltage energy storage module 40 form a charging link. Further, the electric drive motor driving link and the charging link share the second power circuit 220, realizing the mutual integration between the two different links, reducing the number of components required for the operation of the traditional electric drive motor system and the traditional charger system, saving the occupied space, reducing the overall system volume, and realizing the electric drive motor working mode and the vehicle-mounted charger working mode.

[0060] Further, the control device 100 provided in the application reduces the number of components required for the operation of the traditional system, reduces the overall cost and weight, and improves the integration of the overall vehicle system.

[0061] In one embodiment, the second power circuit 220 is configured to drive the electric drive motor 50 to operate according to the electric energy provided by the high-voltage energy storage module 40 when the AC power supply module 30 does not charge the high-voltage energy storage module 40.

[0062] In the embodiment, when the AC power supply module 30 does not charge the high-voltage energy storage module 40, the connection link between the AC power supply module 30 and the air compressor motor 10 is disconnected, and the connection link between the AC power supply module 30 and the second power circuit 220 is also disconnected, so that the second power circuit 220 does not work in the charging link. The electric energy required for the operation of the electric drive motor 50 is provided by the high-voltage energy storage module 40, so that the vehicle is in the electric drive motor working mode, and the vehicle is in the driving state.

[0063] In one embodiment, the electric energy conversion module 20 further comprises at least one third power circuit 230. The third power circuit 230 is connected with the second power circuit 220 and the high-voltage energy storage module 40. The third power circuit 230 and the second power circuit 220 are configured to drive the electric drive motor 50 to operate according to the direct-current electric energy provided by the high-voltage energy storage module 40.

[0064] In the embodiment, the two ends of the third power circuit 230 are connected with the two ends of the second power circuit 220 and the two ends of the high-voltage energy storage module 40, respectively. The high-voltage energy storage module 40, the at least one third power circuit 230, the second power circuit 220, and the electric drive motor 50 form an energy flow link, which can drive the electric drive motor 50 to operate.

[0065] The at least one third power circuit 230 is connected with the second power circuit 220 respectively to the three-phase windings of the electric drive motor 50, forming a three-phase control circuit corresponding to the U-phase, V-phase and W-phase of the three-phase power respectively. Then, the current in the three-phase windings of the electric drive motor 50 changes regularly, thereby forming a rotating magnetic field to drive the electric drive motor 50 to operate.

[0066] In one embodiment, the at least one third power circuit 230 is in an off state when the AC power supply module 30 charges the high-voltage energy storage module 40. The AC power supply module 30, the air compressor motor 10, the at least one first power circuit 210, the second power circuit 220 and the high-voltage energy storage module 40 form a charging link.

[0067] In one embodiment, the third power circuit 230 can also realize the slow pipe function of the second power circuit 220 in the charging link. The circuit connection can be adjusted according to the actual situation, so that the functionality of the third power circuit 230 is expanded, and the integration of the overall vehicle system is further improved.

[0068] In one embodiment, the first power circuit 210 includes a plurality of transistors and a plurality of diodes. The second power circuit 220 includes a plurality of transistors and a plurality of diodes. The third power circuit 230 includes a plurality of transistors and a plurality of diodes. The type of transistor can be an Insulated Gate Bipolar Transistor (IGBT) or a Metal-Oxide-Semiconductor Field-Effect Transistor (SIC MOSFET). The IGBT is a composite full-controlled voltage-driven power semiconductor device composed of BJT and MOSFET. The IGBT has the advantages of high input impedance, low driving power, low on-state voltage drop, large current carrying capacity and good insulation performance between input and output. The SIC MOSFET has the advantages of high voltage resistance, low on-state resistance, high switching speed and good high temperature resistance.

[0069] In one embodiment, the first power circuit 210 includes a first transistor 211 and a second transistor 212. The emitter of the first transistor 211 is connected with the air compressor motor 10. The collector of the first transistor 211 is connected with one end of the high-voltage energy storage module 40. The collector of the second transistor 212 is connected with the emitter of the first transistor 211 and the air compressor motor 10. The emitter of the second transistor 212 is connected with the other end of the high-voltage energy storage module 40.

[0070] The second power circuit 220 includes a third transistor 221 and a fourth transistor 222. The emitter of the third transistor 221 is connected to the other end of the AC power supply module 30. The collector of the third transistor 221 is connected to one end of the high-voltage energy storage module 40. The collector of the fourth transistor 222 is connected to the emitter of the third transistor 221 and the other end of the AC power supply module 30. The emitter of the fourth transistor 222 is connected to the other end of the high-voltage energy storage module 40. The connection end of the collector of the fourth transistor 222 and the emitter of the third transistor 221 is connected to the electric drive motor 50.

[0071] In this embodiment, the first transistor 211 and the second transistor 212 are connected between the two ends of the high-voltage energy storage module 40. The common connection end of the first transistor 211 and the second transistor 212 is connected to the air compressor motor 10, and further connected to one end of the AC power supply module 30. The third transistor 221 and the fourth transistor 222 are connected between the two ends of the high-voltage energy storage module 40. The common connection end of the third transistor 221 and the fourth transistor 222 is connected to the other end of the AC power supply module 30.

[0072] The first transistor 211 and the second transistor 212 form the fast tube of the power factor correction (PFC) circuit, have high switching frequency, can quickly turn on and turn off, have fast response speed, can timely make the current waveform follow the voltage waveform change, thereby improving the power factor, realizing more accurate energy storage and release control.

[0073] When the AC power provided by the AC power supply module 30 is in the positive half cycle, when the first transistor 211 is closed, the second transistor 212 is turned on, and the third transistor 221 is closed, the fourth transistor 222 is turned on, the AC power supply module 30 charges the inductor coil in the air compressor motor 10 to store energy. When the first transistor 211 is turned on, the second transistor 212 is disconnected, and the third transistor 221 is closed, the fourth transistor 222 is turned on, the induced electromotive force generated by the inductor coil in the air compressor motor 10 charges the high-voltage energy storage module 40 with the AC power supply module 30.

[0074] When the AC power provided by the AC power supply module 30 is in the negative half cycle, the third transistor 221 is turned on, the fourth transistor 222 is turned off, and the first transistor 211 is turned on, the second transistor 212 is turned off, the AC power supply module 30 charges the inductor coil in the air compressor motor 10 to store energy. When the third transistor 221 is turned on, the fourth transistor 222 is turned off, and the first transistor 211 is turned off, the second transistor 212 is turned on, the induced electromotive force generated by the inductor coil in the air compressor motor 10 charges the high-voltage energy storage module 40. In this way, the inductor current is controlled by the high-frequency switching action of the first transistor 211 and the second transistor 212, so that the current waveform changes with the voltage waveform, thereby improving the power factor.

[0075] The third transistor 221 and the fourth transistor 222 form a slow tube of the power factor correction circuit, have a low switching frequency, and work with the fast tube to buffer the energy in the circuit and slowly adjust the energy flow to avoid problems such as voltage spikes or current surges caused by rapid changes in inductor energy, so as to ensure more stable power conversion.

[0076] In an embodiment, a diode is connected between the collector and the emitter of each transistor in the first power circuit 210, the second power circuit 220, and the third power circuit 230. When the transistor is turned off, the current in the inductor coil in the air compressor motor 10 cannot change abruptly, an induced electromotive force is generated, and a freewheeling path is formed through the diode to maintain the continuous flow of current. Further, the diode can also protect the transistor from reverse voltage impact and protect the transistor.

[0077] In an embodiment, the circuit structures of the first power circuit 210, the second power circuit 220, and the third power circuit 230 are the same. The turning on or turning off of each transistor in the first power circuit 210, the second power circuit 220, and the third power circuit 230 can be realized by the control signal output by the main control module 910.

[0078] Please refer to Figure 5 In an embodiment, the control device 100 further includes a filter energy storage module 60. The filter energy storage module 60 is connected with the electric energy conversion module 20 and the high-voltage energy storage module 40, respectively, for filtering the voltage during the charging of the high-voltage energy storage module 40 by the AC power supply module 30, and storing the electric energy during the charging of the high-voltage energy storage module 40 by the AC power supply module 30. The filter energy storage module 60 is also used to store the electric energy during the energy supply of the air compressor motor 10 and the electric drive motor 50 by the high-voltage energy storage module 40.

[0079] In this embodiment, the filter and energy storage module 60 is connected in parallel across the two ends of the electric energy conversion module 20, and can also be understood as being connected in parallel across the two ends of the first power circuit 210 and the second power circuit 220 respectively. The filter and energy storage module 60 acts as a switching component in the charging link and filters the pulsating direct current output by the electric energy conversion module 20, so that the direct current signal reaching the high-voltage energy storage module 40 is smoother. Further, the filter and energy storage module 60 can also store energy and maintain the stability of the voltage output to the high-voltage energy storage module 40, thereby playing a role in energy buffering.
