[0045] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0046] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0047] like Figure 1 FIG. 1 is a schematic diagram of a vehicle thermal management system provided by an embodiment of the present invention. Figure 1 The vehicle thermal management system includes a control unit 110 , a functional component 120 , and a thermal management device 130 .

[0048] The functional components 120 are components deployed in the front cabin of the vehicle for maintaining the operation of the vehicle. Each functional component is provided with a temperature sensor for collecting temperature information of each functional component in real time and feeding 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 a coolant, etc.

[0050] The control unit 110 is used to receive temperature information fed back by the temperature sensors carried by each functional component, so as to monitor the temperature of each functional component in real time and determine whether thermal management is required for the functional component. Furthermore, the control unit is also used to obtain the vehicle's operating condition information, such as whether the vehicle is in driving state, charging state, low-voltage battery charging state or sleep state, and obtain the vehicle's driving mode information, such as whether the vehicle is in economy mode, standard mode or sports mode, so as to make a comprehensive judgment on the vehicle's current state. The most reasonable target thermal management method is determined in combination with the vehicle's current state, and the thermal management device is controlled to perform thermal management.

[0051] The thermal management device 130 includes an electronic fan and a water pump, which are used to receive the target thermal management mode instruction output by the control unit, and perform thermal management on each functional component of the front cabin of the vehicle according to the target thermal management mode to achieve cooling of each functional component.

[0052] like Figure 2 As shown, it is a flow chart of a vehicle thermal management method provided by an embodiment of the present invention, and the method is applied to Figure 1 Control unit shown. See Figure 2 The specific steps of the method include:

[0053] S201, obtaining temperature information of each functional component in the vehicle, and determining whether the vehicle is in a drivable state.

[0054] Specifically, the functional components include motors, MCUs, MCU nodes, OBCs, OBC water channels, DCDCs, and coolants. Each functional component that needs to perform temperature control is used as a temperature monitoring point and is provided with at least one temperature sensor. The temperature sensor detects the temperature information of the functional component in real time and feeds the temperature information back to the control unit.

[0055] The control unit obtains the temperature information of each functional component through the temperature sensor, and determines whether the vehicle is in a drivable state or a power-only state to determine whether thermal management needs to be performed on each functional component.

[0056] S202, when the vehicle is in a drivable state, determining the thermal management method of each functional component according to the temperature information of each functional component, the driving mode of the vehicle, and the working condition information of the vehicle.

[0057] Specifically, when it is determined that the vehicle is in a drivable state, the working condition information and driving mode information of the vehicle are determined respectively. The state information of the vehicle is determined according to the temperature information of each functional component, and / or the working condition information of the vehicle, and / or the driving mode information of the vehicle.

[0058] When determining the status information of the vehicle, it is necessary to determine the reasons that may affect the temperature of the functional components, so as to determine the status information of the vehicle according to the corresponding vehicle operating conditions or driving modes.

[0059] When the functional component is a motor, MCU, MCU node, DCDC or coolant, the vehicle status information is determined according to the driving mode of the vehicle and the temperature information of the motor, MCU, MCU node, DCDC or coolant itself.

[0060] When the functional component is an OBC or an OBC water channel, considering that different operating conditions of the vehicle may affect the OBC temperature, it is necessary to determine the vehicle status information based on the vehicle operating condition information, the vehicle driving mode, and the temperature of the OBC or the 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: economic mode, standard mode and sports mode.

[0062] After the state information of the vehicle is determined, the thermal management method of each functional component is determined from preset thermal management rules according to the state information of the vehicle.

[0063] The preset thermal management rules include corresponding relationships between several groups of vehicle status information including various functional components and thermal management methods. The thermal management methods are specifically control parameters of the electronic fan and the water pump. Generally, the control parameters are the duty cycle of the electronic fan and the water pump.

[0064] That is, in the thermal management rules, the best thermal management methods are set for different functional components under the vehicle status information composed of temperature, vehicle driving mode, and / or vehicle operating condition information.

[0065] S203, determining a target thermal management mode according to the thermal management mode of each functional component, and performing thermal management by using the target thermal management mode.

[0066] Specifically, after the thermal management modes of all functional components are determined respectively through the thermal management rules, the thermal management modes of all functional components are arbitrated to determine a unified target thermal management mode.

[0067] Among the thermal management methods of each functional component, the thermal management method with the greatest demand can be determined as the target thermal management method. Alternatively, the thermal management methods of each functional component can be combined to determine the thermal management method that can cover the thermal management of all functional components as the target thermal management method.

[0068] When the target thermal management mode is determined and thermal management is performed by the target thermal management mode, the target electronic fan and the target water pump need to be determined from the PWM fan and the two-stage fan divided into high and low speeds according to the vehicle information. The target management mode is converted into target control parameters applied to the target electronic fan and the target water pump. The determined target control parameters are further output to the target electronic fan and the water pump to drive the target electronic fan and the water pump to perform thermal management based on the target control parameters.

[0069] In the embodiment of the present invention, based on the actual vehicle usage scenario of the user, the thermal management method is determined by the temperature information of the functional components, the driving mode of the vehicle, and the working condition information of the vehicle, which solves the problem of uneven heat distribution of key functional components under different driving modes and vehicle working conditions, making energy distribution more reasonable, improving the energy efficiency and endurance of the vehicle, and ensuring good thermal comfort in different driving modes, enhancing the driving satisfaction of users.

[0070] Among them, the multi-channel cooling requirements are determined by combining the temperature of multiple functional components with the vehicle status, making the thermal management control requirements covering multiple functional components more refined, and being able to accurately control the temperature of specific functional modules, reduce overheating or overcooling, and extend the service life of each functional component. At the same time, the thermal management methods of each functional component are arbitrated to efficiently meet the thermal management requirements of the vehicle system level.

[0071] At the same time, a variety of fan and water pump configurations can be used to meet the needs of different markets and environments.

[0072] The present solution is described below through a specific embodiment.

[0073] The control unit obtains the temperature information of the motor, MCU, MCU node, OBC, OBC water channel, DCDC and coolant through the temperature sensors installed in each functional component. When it is determined that the vehicle is in a drivable state, it further obtains that the vehicle's driving mode is the standard mode and the vehicle's working condition information is the driving state.

[0074] According to the driving mode of the vehicle being the standard mode and the temperature of the motor, a first thermal management method for the motor is determined from the thermal management rules. According to the driving mode of the vehicle being the standard mode and the temperature of the MCU, a second thermal management method for the MCU is determined from the thermal management rules. According to the driving mode of the vehicle being the standard mode and the temperature of the MCU node, a third thermal management method for the MCU node is determined from the thermal management rules. According to the driving mode of the vehicle being the standard mode and the temperature of the DCDC, a fourth thermal management method for the DCDC is determined from the thermal management rules. According to the driving mode of the vehicle being the standard mode and the temperature of the coolant, a fifth thermal management method for the coolant is determined from the thermal management rules.

[0075] According to the vehicle driving mode being the standard mode, the vehicle operating condition information being the driving state, and the temperature of the OBC, a sixth thermal management method for the OBC is determined from the thermal management rules. According to the vehicle driving mode being the standard mode, the vehicle operating condition information being the driving state, and the temperature of the OBC water channel, a seventh thermal management method for the OBC water channel is determined from the thermal management rules.

[0076] Among them, the thermal management method is the duty cycle of the electronic fan and water pump.

[0077] After determining the thermal management methods for all functional modules, the thermal management methods are arbitrated and the first thermal management method with the greatest demand is determined as the target thermal management method, so that thermal management is uniformly performed on each functional component using the first thermal management method as the target thermal management method.

[0078] The types of the target electronic fan and the target water pump are determined according to the vehicle information. For example, a PWM fan is determined as the target electronic fan. According to the types of the target electronic fan and the target water pump, the duty cycle in the target parameter is converted into the required duty cycle signal of the target electronic fan and the target water pump, and output to the target electronic fan and the target water pump to drive them to perform thermal management.

[0079] Corresponding to the above vehicle thermal management method, the present application embodiment also provides a vehicle thermal management device. Figure 3 , is a structural schematic diagram of a vehicle thermal management device provided in an embodiment of the present 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 each functional component 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 according to the temperature information of each functional component, the driving mode of the vehicle, and the working condition information of the vehicle when the vehicle is in a drivable state.

[0082] The thermal management module 303 determines a target thermal management mode according to the thermal management modes of the functional components, and performs thermal management through the target thermal management mode.
