[0045] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0046] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0047] like Figure 1 The diagram shown is a structural schematic of a vehicle thermal management system according to an embodiment of the present invention. (See also...) Figure 1 The vehicle thermal management system includes a control unit 110, functional components 120, and thermal management equipment 130.
[0048] Functional components 120 are various components deployed in the front compartment of the vehicle to maintain vehicle operation. Each functional component is equipped with a temperature sensor to collect temperature information of each functional component in real time and feed the collected temperature information back to the control unit.
[0049] In some embodiments, the functional components may specifically include a motor, a microcontroller unit (MCU), an MCU node, an on-board charger (OBC), an OBC water channel, a DC-to-DC converter (DCDC), and coolant, etc.
[0050] The control unit 110 receives temperature information from the temperature sensors mounted on each functional component to monitor the temperature of each component in real time and determine whether thermal management is required. Furthermore, the control unit also acquires vehicle operating condition information, such as whether the vehicle is in driving, charging, low-voltage battery charging, or dormant mode, as well as driving mode information, such as whether the vehicle is in Eco, Standard, or Sport mode, to comprehensively assess the vehicle's current status. Based on the vehicle's current status, the most appropriate target thermal management method is determined, and the thermal management equipment is controlled to perform thermal management.
[0051] The thermal management device 130 includes an electric fan and a water pump, which are used to receive instructions on the target thermal management mode output by the control unit, and perform thermal management on each functional component in the front compartment of the vehicle according to the target thermal management mode, so as to achieve cooling of each functional component.
[0052] like Figure 2 The diagram shows a flowchart of a vehicle thermal management method provided in an embodiment of the present invention. This method is applied to vehicles such as... Figure 1 The control unit shown. See also Figure 2 The specific steps of this method include:
[0053] S201: Obtain temperature information of various functional components in the vehicle and determine whether the vehicle is in a drivable state.
[0054] Specifically, the functional components include motors, MCUs, MCU nodes, OBCs, OBC water channels, DC-DC converters, and coolant. Each functional component requiring temperature control acts as a temperature monitoring point and is equipped with at least one temperature sensor. The temperature sensors detect the temperature information of the functional components in real time and feed the temperature information back to the control unit.
[0055] The control unit obtains temperature information of each functional component through temperature sensors and determines whether the vehicle is in a drivable state or just powered on, in order to determine whether thermal management needs to be performed on each functional component.
[0056] S202, when the vehicle is in a drivable state, the thermal management method of each functional component is determined according to the temperature information of each functional component, the driving mode of the vehicle, and the operating condition information of the vehicle.
[0057] Specifically, once the vehicle is determined to be drivable, its operating condition information and driving mode information are determined separately. The vehicle's status information is determined based on the temperature information of each functional component, and / or the vehicle's operating condition information, and / or the vehicle's driving mode information.
[0058] When determining the vehicle's status information, it is necessary to specifically identify the causes that may affect the temperature of the functional components, and then determine the vehicle's status information based on the corresponding vehicle operating conditions or driving mode.
[0059] When the functional components are motors, MCUs, MCU nodes, DC-DC converters, or coolants, the vehicle's status information is determined based on the vehicle's driving mode and the temperature information of the motor, MCU, MCU node, DC-DC converter, or coolant itself.
[0060] When the functional component is an OBC or OBC water channel, considering that different vehicle operating conditions may affect the OBC temperature, it is necessary to determine the vehicle's status information based on the vehicle's operating condition information, the vehicle's driving mode, and the temperature of the OBC or OBC water channel itself.
[0061] The vehicle's operating information includes: driving status, charging status, low-voltage battery charging status, and sleep status. The vehicle's driving modes include: Eco mode, Standard mode, and Sport mode.
[0062] After determining the vehicle's status information, the thermal management method for each functional component is determined from the preset thermal management rules based on the vehicle's status information.
[0063] The preset thermal management rules include a correspondence between several sets of vehicle status information and thermal management methods for various functional components. Specifically, the thermal management methods are the control parameters for the electric fan and water pump. Generally, the control parameters are the duty cycles of the electric fan and water pump.
[0064] That is, in the thermal management rules, for different functional components, under the vehicle status information composed of temperature, vehicle driving mode, and / or vehicle operating condition information, there is a corresponding optimal thermal management method.
[0065] S203, determine the target thermal management method based on the thermal management method of each functional component, and execute thermal management through the target thermal management method.
[0066] Specifically, after determining the thermal management methods of all functional components through thermal management rules, the thermal management methods of all functional components are arbitrated to determine a unified target thermal management method.
[0067] Among these options, the thermal management method with the highest demand among the thermal management methods of each functional component can be identified as the target thermal management method. Alternatively, the thermal management methods of each functional component can be combined, and the thermal management method that can cover thermal management of all functional components can be identified as the target thermal management method.
[0068] When determining and implementing the target thermal management method, it is necessary to identify the target electric fan and the target water pump from among the PWM fan and the two-stage fan (high and low speed) based on vehicle information. The target management method is then converted into target control parameters applicable to the target electric fan and the target water pump. These determined target control parameters are further output to the target electric fan and the water pump to drive them to perform thermal management based on these parameters.
[0069] In this embodiment of the invention, based on the user's actual vehicle usage scenarios, the thermal management method is determined by using temperature information of functional components, vehicle driving mode, and vehicle operating condition information. This solves the problem of uneven heat distribution of key functional components under different driving modes and vehicle operating conditions, resulting in more rational energy allocation and improved vehicle energy efficiency and range. It also ensures good thermal comfort in different driving modes, enhancing user driving satisfaction.
[0070] Furthermore, by combining the temperatures of multiple functional components with vehicle status, multi-path cooling requirements are determined, enabling more refined thermal management control covering multiple functional components. This allows for precise temperature control of specific functional modules, reducing overheating or overcooling and extending the lifespan of each component. Simultaneously, arbitration processing of the thermal management methods for each functional component efficiently meets the thermal management requirements of the entire vehicle system.
[0071] At the same time, it can be equipped with a variety of fan and water pump configurations to meet the needs of different markets and environments.
[0072] The following specific embodiment illustrates this solution.
[0073] The control unit acquires temperature information for the motor, MCU, MCU node, OBC, OBC water channel, DC-DC converter, and coolant via temperature sensors installed in various functional components. Once the vehicle is determined to be drivable, the control unit further acquires the vehicle's driving mode (standard mode) and its operating status (driving status).
[0074] Based on the vehicle's standard driving mode and the motor temperature, a first thermal management method is determined from the thermal management rules. Based on the vehicle's standard driving mode and the MCU temperature, a second thermal management method is determined from the thermal management rules. Based on the vehicle's standard driving mode and the MCU node temperature, a third thermal management method is determined from the thermal management rules. Based on the vehicle's standard driving mode and the DC-DC converter temperature, a fourth thermal management method is determined from the thermal management rules. Based on the vehicle's standard driving mode and the coolant temperature, a fifth thermal management method is determined from the thermal management rules.
[0075] Based on the vehicle's driving mode being standard mode, the vehicle's operating information being driving status, and the OBC temperature, a sixth thermal management method for the OBC is determined from the thermal management rules. Based on the vehicle's driving mode being standard mode, the vehicle's operating information being driving status, and the OBC water temperature, a seventh thermal management method for the OBC water system is determined from the thermal management rules.
[0076] The thermal management method involves the duty cycle of electric fans and water pumps.
[0077] After determining the thermal management methods for all functional modules, the thermal management methods are arbitrated, and the thermal management method with the greatest demand is determined as the target thermal management method. The thermal management of each functional component is then uniformly performed by using the first thermal management method as the target thermal management method.
[0078] The types of the target electric fan and target water pump are determined based on vehicle information. For example, a PWM fan is identified as the target electric fan. Based on the types of the target electric fan and target water pump, the duty cycle in the target parameters is converted into the required duty cycle signal for the target electric fan and target water pump, and output to the target electric fan and target water pump to drive them to perform thermal management.
[0079] Corresponding to the above-described vehicle thermal management method, this application also provides a vehicle thermal management device. See [link to previous document]. Figure 3 This is a schematic diagram of the structure of a vehicle thermal management device provided in an embodiment of this application. The vehicle thermal management device may include: an acquisition module 301, a determination module 302, and a thermal management module 303.
[0080] The acquisition module 301 acquires the temperature information of various functional components in the vehicle and determines whether the vehicle is in a drivable state.
[0081] The determination module 302 determines the thermal management method of each functional component based on the temperature information of each functional component, the driving mode of the vehicle, and the operating condition information of the vehicle when the vehicle is in a drivable state.
[0082] The thermal management module 303 determines a target thermal management method based on the thermal management methods of each functional component, and performs thermal management through the target thermal management method.
