Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of thermal management actuators, and in particular to an actuator control method. Background Art

[0002] At present, the technology of new energy vehicles is iterating and updating, and integrated thermal management of the whole vehicle based on new energy is a development trend and direction. The control of the actuators of multiple circuits (battery circuit, motor circuit, air conditioning refrigeration circuit) is placed in one controller, evolving towards a highly integrated direction, with a more compact layout. By using multi-channel valves or pipelines, some circuits in the battery, motor electronic control and air conditioning system are connected to form a large circulation loop, which improves energy utilization. On the other hand, reducing multiple controllers to one integrated controller can reduce costs.

[0003] The integrated thermal management actuator mainly includes a battery circuit water pump, a motor circuit water pump, a multi-way valve that connects the circuits in series, an air conditioning circuit expansion valve and a solenoid valve. The multi-way valve is generally a brushed DC motor with a built-in reducer and Hall position sensor. The Hall sensor has two parameters, period and duty cycle, and the multi-way valve position is characterized by the period and duty cycle signals.

[0004] Generally, vehicle manufacturers will choose two backups at points A and B on the actuator, but there are differences in the actuators at points A and B, including the different periods of the Hall position signals built into the multi-way valve, the different motor parameters of the water pump, and the different travels of the expansion valve. This requires that the controller must match the control parameters of different actuators in order for the software to achieve the same control performance. Therefore, different actuators require the controller to automatically match different types of actuators for control. However, how to determine whether the matching actuator is point A or point B requires a reasonable and effective method to determine. Summary of the invention

[0052] Embodiment 1

[0053] Figure 1 is a flow chart of an actuator control method in an embodiment of the present invention. This embodiment is applicable to the case of thermal management actuator control. The method can be executed by the actuator control device in the embodiment of the present invention. The device can be implemented in software and / or hardware, such as Figure 1 As shown, the method specifically comprises the following steps:

[0054] S101, obtaining a Hall signal corresponding to a multi-way valve in an actuator to be determined that is connected to a controller, and determining a first type corresponding to the actuator to be determined according to the Hall signal.

[0055] In this embodiment, the controller may be a thermal management controller of an actuator including multiple circuits (battery circuit, motor circuit, air conditioning refrigeration circuit) in a new energy vehicle. In actual operation, the controller may be a controller in an MCU (Microcontroller Unit), which can control the actuator connected thereto.

[0056] It should be noted that the actuator to be determined may be an actuator of a type to be determined connected to the controller. Generally, different types of actuators have different periods of Hall position signals built into the multi-way valve in the actuator, different motor parameters of the water pump, and different travels of the expansion valve. Therefore, different actuators require the controller to automatically match different types of actuators for control.

[0057] In this embodiment, the Hall signal corresponding to the multi-way valve may be a Hall position signal collected by a Hall position sensor built into the multi-way valve.

[0058] The first type may be the type of the actuator to be determined and connected to the controller, determined by the controller according to the collected Hall signal.

[0059] Specifically, the controller obtains a Hall signal corresponding to a multi-way valve in the actuator to be determined that is connected to the controller, and identifies the Hall signal, thereby determining the first type corresponding to the actuator to be determined.

[0060] S102: Receive a configuration instruction sent by a vehicle control unit, and parse the configuration instruction to obtain a second type corresponding to the actuator to be determined.

[0061] In this embodiment, the vehicle control unit may be a VCU (Vehicle Control Unit), and the VCU and the controller may be connected and communicated based on a LIN (Local Interconnect Network) / CAN (Controller Area Network) bus.

[0062] It should be noted that the configuration instruction may be an instruction sent by the VCU to the controller via the LIN / CAN bus to configure the type of actuator connected to the controller.

[0063] The second type may be the type of the actuator to be determined connected to the controller given by the VCU and determined by the controller after parsing the received configuration instruction.

[0064] Specifically, the VCU sends a configuration instruction to the controller via the LIN / CAN bus, and the controller parses the received configuration instruction to obtain the second type of the actuator to be determined connected to the controller given by the VCU.

[0065] In this embodiment, the execution order of step S101 and step S102 is not limited. In one embodiment, step S101 may be executed first and then step S102; in another embodiment, step S102 may be executed first and then step S101; in other embodiments, step S101 and step S102 may be executed simultaneously.

[0066] S103: Determine a target type of the actuator to be determined according to the first type and the second type.

[0067] The target type may be the type of the actuator to be determined and connected to the controller, which is determined based on the fusion of the Hall signal and the configuration instruction.

[0068] Specifically, after the types of the actuators to be determined connected to the controller are determined respectively in two ways, the target type of the actuators to be determined is finally determined based on the fusion determination strategy according to the two results.

[0069] S104: Control the actuator to be determined according to the target type of the actuator to be determined.

[0070] Specifically, after the target type of the actuator to be determined is determined according to the fusion determination strategy, the control parameters of each load in the actuator to be determined in the current power-on cycle are matched according to the target type of the actuator to be determined, and the controller controls the actuator to be determined based on these control parameters. In actual operation, after the type of the actuator to be determined is determined, the current power-on cycle will not be changed.

[0071] The embodiment of the present invention obtains the Hall signal corresponding to the multi-way valve in the actuator to be determined connected to the controller, determines the first type corresponding to the actuator to be determined according to the Hall signal, receives the configuration instruction sent by the vehicle control unit, and parses the configuration instruction to obtain the second type corresponding to the actuator to be determined, determines the target type of the actuator to be determined according to the first type and the second type, and controls the actuator to be determined according to the target type of the actuator to be determined. Through the technical solution of the present invention, the period of the Hall signal corresponding to the multi-way valve in the actuator connected to the controller and the configuration instruction transmitted by the vehicle control unit are fused and judged, so that the type of the actuator of the load can be reasonably and accurately determined, and then the actuator can be effectively controlled according to the type of the actuator.

[0072] Optionally, obtaining a Hall signal corresponding to a multi-way valve in the actuator to be determined connected to the controller, and determining the first type corresponding to the actuator to be determined according to the Hall signal includes:

[0073] A Hall signal corresponding to a multi-way valve in an actuator to be determined connected to a controller is obtained.

[0074] Specifically, the controller obtains a Hall signal corresponding to a multi-way valve in the actuator to be determined connected to the controller.

[0075] Get the period information of the Hall signal.

[0076] It can be known that the Hall signal can be a square wave signal with a certain periodicity. In actual operation, the controller can be driven by the ICU (Input Capture Unit) to identify the sampling period of the Hall position signal corresponding to the multi-way valve. Exemplarily, the Hall signal can be, for example, a frequency of 500 Hz, that is, a period of 2 milliseconds.

[0077] The period information of the Hall signal is compared with the period range corresponding to each actuator in the preset actuator set.

[0078] The actuator set includes actuators of the first type and actuators of the second type.

[0079] It should be noted that the type range of the actuator to be determined connected to the controller can be predetermined, that is, which actuators are included in the actuator set can be determined, for example, the preset actuator set can include Class A actuators or Class B actuators. If the type of actuator is different, the frequency and period information of the Hall signal corresponding to the multi-way valve in the actuator may also be different. It can be known that the frequency range of the Hall signal corresponding to each actuator can be known in advance. For example, for example, the frequency range corresponding to Class A actuator is 400-600Hz, that is, the period range corresponding to Class A actuator is approximately 1.667 milliseconds to 2.5 milliseconds; the frequency range corresponding to Class B actuator is 700-900Hz, that is, the period range corresponding to Class B actuator is approximately 1.111 milliseconds to 1.429 milliseconds.

[0080] Specifically, the period information of the identified Hall signal is compared with the period range corresponding to each actuator in the preset actuator set to determine which specific actuator in the preset actuator set has the period range that matches the period information of the Hall signal.

[0081] The type of the actuator whose period range matches the period information of the Hall signal is determined as the first type.

[0082] Specifically, if the period information of the identified Hall signal falls within the period range corresponding to a certain actuator in the preset actuator set, it can be considered that the type of the actuator to be determined connected to the controller is the type of the actuator in the actuator set. Exemplarily, the period of the Hall signal can be, for example, 2 milliseconds, the period range corresponding to the Class A actuator is approximately 1.667 milliseconds to 2.5 milliseconds, and the frequency range corresponding to the Class B actuator is 700-900 Hz, that is, the period range corresponding to the Class B actuator is approximately 1.111 milliseconds to 1.429 milliseconds. It can be seen that the period information of the Hall signal falls within the period range corresponding to the Class A actuator in the preset actuator set, and it can be considered that the type of the actuator to be determined connected to the controller is Class A.

[0083] Optionally, after comparing the period information of the Hall signal with the period range corresponding to each actuator in the preset actuator set, the method further includes:

[0084] If the period information of the Hall signal does not match the period range corresponding to each actuator in the preset actuator set, the Hall signal is determined to be invalid information.

[0085] It should be explained that invalid information can be understood as the identified Hall signal exceeds the cycle range corresponding to all types of actuators that may be connected to the controller. The collected Hall signal can be considered invalid, that is, the configuration obtained by the multi-way valve sampling period is unreliable.

[0086] Specifically, the period information of the identified Hall signal is compared with the period range corresponding to each actuator in the preset actuator set. If the period information of the Hall signal does not match the period range corresponding to each actuator in the preset actuator set, it can be confirmed that the Hall signal is invalid information.

[0087] Optionally, determining the target type of the actuator to be determined according to the first type and the second type includes:

[0088] If the first type and the second type are different, and the Hall signal is invalid information, the target type of the actuator to be determined is determined to be the second type.

[0089] Specifically, if the type of the actuator to be determined according to the Hall signal is inconsistent with the type of the actuator to be determined according to the configuration instruction, and the collected Hall signal is invalid information, the target type of the actuator to be determined can be determined according to the configuration instruction sent by the VCU.

[0090] Optionally, determining the target type of the actuator to be determined according to the first type and the second type includes:

[0091] If the first type and the second type are different, and the Hall signal is not invalid information, the target type of the actuator to be determined is determined to be the first type.

[0092] Specifically, if the type of the actuator to be determined based on the Hall signal is inconsistent with the type of the actuator to be determined based on the configuration instruction, and the collected Hall signal is valid, the configuration obtained through the multi-way valve sampling period can be used preferentially to determine the target type of the actuator to be determined.

[0093] Optionally, obtaining a Hall signal corresponding to a multi-way valve in an actuator to be determined connected to the controller includes:

[0094] After the multi-way valve in the actuator to be determined connected to the controller is powered on and a preset time period has passed, a Hall signal corresponding to the multi-way valve in the actuator to be determined connected to the controller is obtained.

[0095] The preset time period may be a time period pre-set by the user according to actual conditions or experience values. When the multi-way valve is powered on and the preset time period has passed, it can be considered that the power supply of the multi-way valve is stable. Specifically, this embodiment does not limit the preset time period. Preferably, the preset time period may be, for example, 100 milliseconds.

[0096] Specifically, after the thermal management controller is powered on and the power supply to the multi-way valve is stable, the Hall signal is collected and determined, and the periodic information of the Hall signal is identified.

[0097] Optionally, if the first type and the second type are different, a fault signal is sent to the vehicle control unit.

[0098] The fault signal may be a signal indicating that the actuator configuration given by the VCU is inconsistent with the actuator configuration determined according to the Hall signal.

[0099] Specifically, if the type of the actuator to be determined according to the Hall signal is inconsistent with the type of the actuator to be determined according to the configuration instruction, a configuration inconsistency fault signal needs to be sent to the LIN / CAN bus to the VCU.

[0100] Optionally, determining the target type of the actuator to be determined according to the first type and the second type includes:

[0101] If the first type and the second type are the same, the target type of the actuator to be determined is determined to be the first type.

[0102] Specifically, if the target types of the actuator to be determined determined by the two methods are consistent, normal control is performed.

[0103] Optionally, controlling the actuator to be determined according to the target type of the actuator to be determined includes:

[0104] The control parameters corresponding to each load in the actuator to be determined are determined according to the target type of the actuator to be determined.

[0105] The load includes: at least one of a battery circuit water pump, a motor circuit water pump, an expansion valve, a solenoid valve and a multi-way valve.

[0106] It should be noted that the control parameters corresponding to each load may be parameters for controlling the normal operation of each load. For example, the control parameters corresponding to each load may include: period information of the Hall position signal built into the multi-way valve, motor parameters of the water pump, travel of the expansion valve, etc.

[0107] Specifically, after the final target type of the actuator to be determined is determined according to the fusion determination strategy, the control parameters corresponding to each load in the actuator to be determined are selected according to the target type of the actuator to be determined.

[0108] The actuator to be determined is controlled to execute based on the control parameters corresponding to each load in the actuator to be determined.

[0109] Specifically, after selecting control parameters corresponding to each load in the actuator to be determined according to the target type of the actuator to be determined, the actuator to be determined is controlled to execute based on these control parameters.

[0110] As an exemplary description of an embodiment of the present invention, Figure 2 Schematic diagram of an actuator control method in an embodiment of the present invention. Figure 2 As shown, VCU communicates with MCU via LIN / CAN. MCU includes controller (i.e., controller). A / B actuator (i.e., actuator to be determined) is connected to the controller. A / B actuator includes loads: motor / battery water pump, expansion valve, SOV valve (SOV valve usually refers to idle air control valve, Idle Air Control Valve, also known as idle throttle actuator Idle Throttle Actuator, which is an important component in modern automobile engine management system. The main function of SOV valve is to control the amount of air entering the engine at idle speed to maintain a stable idle speed) and multi-way valve. The controller identifies the Hall signal corresponding to the multi-way valve in the A / B actuator through the ICU driver, and determines the type of the A / B actuator based on the Hall signal. In addition, the controller determines the type of the A / B actuator by parsing the configuration instructions sent by VCU, and then determines the final type of the A / B actuator based on the types of the actuators determined in the two ways. After determining the type of the A / B actuator, select the control parameters corresponding to the type to control the A / B actuator.

[0111] Figure 3is a schematic diagram of a fusion determination strategy in an embodiment of the present invention, such as Figure 3 As shown, the controller collects and determines the Hall signal, identifies the Hall signal period and validity, and determines the actuator type according to the Hall signal; the controller receives the configuration instruction sent by the VCU, parses the configuration instruction to determine the load configuration, that is, determines the actuator type; then the actuator type results determined by the two methods are used to determine the load selection based on the fusion determination strategy, that is, determines the actuator type; after determining that the actuator is an A / B actuator, the corresponding actuator control parameters are selected to control the actuator. Exemplarily, the specific fusion determination strategy can be described as: if the actuator types obtained by the two methods are consistent, normal control is performed; if they are inconsistent, the configuration obtained through the multi-way valve sampling period is used first; if the configuration obtained through the multi-way valve sampling period is unreliable (the attached validity information is invalid), the actuator type is determined according to the configuration instruction sent by the VCU.

[0112] The technical solution of the embodiment of the present invention provides a thermal management actuator load fusion determination strategy, which determines whether the load actuator is type A or type B based on the period information of the Hall sensor built into the multi-way valve and the configuration instructions transmitted through the VCU. After determination, different control parameters are selected according to the type A actuator or type B actuator for control. Through the technical solution of the present invention, the period of the Hall signal corresponding to the multi-way valve in the actuator connected to the controller and the configuration instructions transmitted through the vehicle control unit are fused and judged, so that the type of the load actuator can be reasonably and accurately determined, and then the actuator can be effectively controlled according to the type of actuator.
