Description

Technical Field

[0001] This invention relates to the field of thermal management control for new energy vehicles, and specifically to automotive thermal management control methods and systems. Background Technology

[0002] As vehicle emission regulations become increasingly stringent and requirements continue to rise, and the new energy vehicle credit system is being widely implemented, new energy electric vehicle models and R&D projects are showing a rapid growth trend. The industry transformation is in-depth, and software-defined vehicles are moving from theory to practice. This requires continuous upgrading and optimization of communication methods, control strategies, and signal processing rules and methods to improve control accuracy and solve communication redundancy and invalid communication problems.

[0003] In traditional vehicle domain controllers, signal transmission is relatively direct and simple. Most signals such as the operating status and faults of the actuators are collected and directly forwarded to the network. There is little integration or filtering based on system principles and the actual needs of the controller receiving nodes. This often reduces the accuracy of control and the communication efficiency of network signals, resulting in signal redundancy. Summary of the Invention

[0004] This invention provides a method and system for automotive thermal management control. It addresses the problem that traditional vehicle domain controllers rely on relatively direct and simple signal transmission, often simply collecting signals such as the operating status and faults of actuators and directly forwarding them to the network. This approach rarely incorporates targeted integration and filtering based on system principles and the actual needs of the controller's receiving nodes, often reducing control accuracy and network signal communication efficiency, and leading to signal redundancy.

[0044] On the one hand, an automotive thermal management control method M100 is provided, which includes:

[0045] S101. Obtain the operating status information and fault information of each sub-component in the automotive system.

[0046] S102. Determine the impact level of the operating status and faults of each sub-component on the operation of the vehicle system based on the operating status information and fault information of each sub-component in the vehicle system.

[0047] S103. Identify the sub-components located within the preset influence level.

[0048] S104. Control the operation of the vehicle based on the operating status information and fault information of sub-components located within the preset influence level.

[0049] This invention acquires the operating status and fault information of each sub-component in a vehicle system; determines the impact level of the sub-component's operating status and fault on the vehicle system's operation based on this information; identifies sub-components within a preset impact level; and controls the vehicle's operation based on the operating status and fault information of these sub-components. By processing and filtering effective signals, redundant signals unnecessary for the vehicle controller are eliminated, reducing the vehicle controller's processing of operating status and fault information from each sub-component. The controller only needs to process the operating status and fault information of sub-components that substantially affect vehicle operation, reducing the information processing load and computational burden on the vehicle controller, thereby improving its information processing efficiency and avoiding delay and matching problems caused by the vehicle controller simultaneously acquiring and calculating information from multiple sub-components.

[0050] S101. Obtain the operating status information and fault information of each sub-component in the automotive system.

[0051] In an optional embodiment of the present invention, obtaining the operating status information and fault information of each sub-component in the automotive system includes:

[0052] Obtain operating status and fault information for electric compressors, high-voltage electric heaters, water valves, water pumps, and fans.

[0053] The embodiments of the present invention can collect the independent status and fault information of each sub-component, such as electric compressor, high-voltage electric heater, water pump (motor circuit, battery circuit and passenger compartment circuit), water valve (motor circuit, battery circuit and passenger compartment circuit), and electronic expansion valve (battery circuit and passenger compartment circuit), through the thermal management control module in the new energy vehicle.

[0054] Furthermore, in this embodiment of the invention, the collected operating status information and fault information of each sub-component are converted into status information and fault information at the system level (battery cooling and heating, motor cooling) for feedback and signal transmission.

[0055] S102. Determine the impact level of the operating status and faults of each sub-component on the operation of the vehicle system based on the operating status information and fault information of each sub-component in the system.

[0056] The operating status and malfunctions of different sub-components have varying degrees of impact on the vehicle system. For example, while an overcurrent in the battery water pump might affect the flow rate of the vehicle system, potentially extending battery cooling time, it wouldn't affect the overall operational safety of the vehicle. Conversely, a compressor failure would prevent the battery from cooling effectively, impacting power output.

[0057] S103. Identify the sub-components located within the preset influence level.

[0058] The sub-components included in the embodiments of the present invention may include an electric compressor, a high-voltage electric heater, a water pump, a water valve, and an electronic expansion valve. By determining the preset influence level of each of the above sub-components, the influence level of each sub-component on the vehicle can be determined.

[0059] S104. Control the operation of the vehicle based on the operating status information and fault information of sub-components located within the preset influence level.

[0060] When the operating status or malfunction of a sub-component affects the normal operation of the vehicle, the vehicle's operation is controlled based on the sub-component's operating status and malfunction information, such as controlling the vehicle to operate at reduced power. When the operating status or malfunction of a sub-component can maintain the normal operation of the vehicle, the vehicle is controlled to operate normally without shutting down, but a symbolic or text-based pop-up reminder can be displayed through the vehicle system's display module (such as an in-vehicle display screen).

[0061] In one optional embodiment of the present invention, the impact level includes a first impact level and a second impact level.

[0062] The first level of impact can include faulty (the vehicle's heating system is malfunctioning, affecting battery heating, and requiring power output limitation based on actual usage conditions) and faulty (the vehicle's cooling or heat dissipation system is malfunctioning, affecting motor or battery cooling, and requiring power output limitation based on actual usage conditions). The second level of impact can include no fault (the vehicle system is operating normally) and faulty (a diagnostic fault occurs in a sub-component of the vehicle's heating or cooling system, but it has self-recovery capabilities, and the vehicle does not stop).

[0063] Please see Figure 2 S103. Determine the sub-components located within the preset influence level, including:

[0064] S1031. When the operating status and fault of a sub-component are at the first level of impact, the operating status and fault of the sub-component will affect the normal operation of the vehicle.

[0065] In other words, when it is determined that the sub-component is located at the first level of impact on the vehicle, the operating status of the sub-component and the faults generated by the sub-component will affect the normal operation of the vehicle. That is, if the sub-component is faulty, the vehicle system will be malfunctioning and the vehicle will not be able to work normally, requiring power limiting; or if the sub-component is faulty, the vehicle system will be under high voltage, and the vehicle will not be able to work normally, requiring power limiting.

[0066] S1032. When the operating status and fault of a sub-component are at the second level of impact, the operating status and fault of the sub-component will not affect the normal operation of the vehicle.

[0067] In other words, when it is determined that the sub-component's impact on the vehicle is at the second level of influence, the sub-component's operating status and the faults it causes will not affect the normal operation of the vehicle. That is, if the sub-component is fault-free, the vehicle system will operate normally, or if the sub-component is faulty but has a self-recovery function, it can operate normally without shutting down.

[0068] In one optional embodiment of the present invention, please refer to Figure 3 S104. Controlling the operation of the vehicle based on the operating status information and fault information of sub-components located within a preset influence level, including:

[0069] S1041. When the operating status and fault of a sub-component are at the first level of impact, the vehicle is controlled to operate in the first operating state. Under the first operating state operating conditions, the vehicle reduces its operating performance but does not stop.

[0070] S1042. When the operating status and fault of a sub-component are at the second level of influence, the vehicle is controlled to operate in the second operating state. Under the operating conditions of the second operating state, the vehicle operates normally.

[0071] As an example, the sub-component can be the PT sensor of the refrigeration system. If the operating status information of the PT sensor is normal, then the second level of influence of the PT sensor of the refrigeration system on the operation of the whole vehicle is normal, that is, it does not affect the operation of the vehicle system.

[0072] As an example, a sub-component could be a heater high-pressure fault. If the heater high-pressure fault is a non-self-recovering fault, then the first level of impact of the heater high-pressure fault on the operation of the vehicle system is abnormal, affecting the vehicle's power output.

[0073] In an optional embodiment of the present invention, obtaining the operating status information and fault information of each sub-component in the automotive system includes:

[0074] Acquire the initial operating status information and initial fault information of each sub-component in the automotive system;

[0075] The operating status and fault information of each sub-component in the automotive system are converted into operating status and fault information of each sub-component, with the automotive thermal management system as the unit.

[0076] As an example, the sub-component can be the PT sensor of the refrigeration system, the initial operating status information and initial fault information of the PT sensor, and convert the PT sensor of the refrigeration system, the initial operating status information and initial fault information of the PT sensor of the refrigeration system into the operating status information and fault information of the PT sensor of the refrigeration system at the level of the automotive thermal management system (e.g., automotive battery cooling and heating, motor cooling).

[0077] The embodiments of the present invention compare the differences between the signal lists of the thermal management control signals in the automotive system of the related art (Table 1) before processing and those of the embodiments of the present invention (Table 2) after processing.

[0078] Table 1. Relevant technologies and conventional design of signal matrices

[0079]

[0080]

[0081]

[0082]

[0083] Note: In the signal description, 0x0 represents the default value, 0x1 represents that the diagnosis has been completed and there is no fault, 0x2 represents that the diagnosis has not been completed, and 0x3 represents that the diagnosis has been completed and there is a fault; T represents the transmitting controller of the signal, and R represents the receiving controller of the signal.

[0084] Table 1 shows that the thermal management control module in the automotive system provided by related technologies collects the actuator fault signals of the motor cooling system circuit and the battery cooling and heating system circuit one by one and sends them directly to the VCU (Vehicular Communication Unit) for system fault judgment. This signal can also be used for component diagnosis. Among them, the water pump signal occupies 24 bits, the refrigerant solenoid valve occupies 32 bits, the electric compressor occupies 16 bits, and the high-voltage electric heater occupies 14 bits. The signal storage is large and the processing is relatively complex. In addition, the actual operating status of the corresponding system cannot be directly determined based solely on the existence of the component fault status signal in the VCU. For example, if the water pump control signal communication fails, after the VCU collects the signal, it is also necessary to collect the water temperature signal of the corresponding circuit and make a comprehensive calculation of the actual working status of the corresponding circuit, such as delay strategy. This increases the software code and the computing load of the controller.

[0085] Table 2. Optimized signal processing matrix

[0086]

[0087] Table 2 shows the results of the thermal management control module in the automotive system provided by this invention. After collecting faults from all actuators, the module merges similar faults into two categories, consuming a total of 5 bits: Fault present (the heating system is limited, affecting battery heating; power output is limited based on actual usage environment requirements) and Fault present (the cooling system is limited, affecting motor cooling or battery cooling; power output is limited based on actual usage environment requirements). The module also considers the principles of automotive engine thermal management system development (one key technology in engine thermal management system development is the matching technology between the thermal management system and engine operation, as well as the selection of system optimization control strategies. The efficiency of the thermal management system largely depends on the system optimization control strategy, and the controlled objects include water pump speed, electronic thermostat valve opening, and cooling fan speed). The second level of impact can include no fault (the vehicle system is working normally) and faulty (the heating and cooling system sub-components of the vehicle have diagnostic faults, but have self-recovery capabilities, and the vehicle does not stop). The signal transmission is completed, and the VCU directly collects and judges the data without adding extra judgment conditions, which reduces the pressure on the controller software code and storage, and further reduces the network load.
