[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0054] Most of the existing distribution controls for motor heat generation mechanically and fixedly supply components inside the vehicle such as the battery and the passenger compartment. With the development of electrification and intelligence, it is not only necessary to ensure that the components inside the vehicle maintain the optimal working temperature, but also the requirement for the overall vehicle energy utilization rate is getting higher and higher. At the same time, people's requirements for the thermal comfort of vehicle heating and cooling are constantly increasing, and the driving range has become the main pain point of new energy vehicles. However, the current solutions for motor heat generation distribution still mechanically distribute, and cannot solve the problems of low energy utilization rate, affecting the driving range, and high overall vehicle energy consumption during the control and distribution of current motor heat generation.

[0055] The core concept of this application is to integrate the prediction of the driver's habitual actions, so that the motor heat generation corresponding to the next moment can be determined in advance, and based on this habitual information, the motor heat generation can be reasonably distributed to supply components inside the vehicle.

[0056] As Figure 1 shown, an embodiment of one aspect of the present invention provides a thermal management method for a vehicle, which is applied to a cockpit. The cockpit is assembled on a moving vehicle and includes:

[0057] S1: Obtain the current navigation information of the vehicle and the driving habit information of the driver.

[0058] S2: Determine the thermal management method for at least one component inside the vehicle according to the navigation information and the driving habit information of the driver;

[0059] S3: Perform thermal management on all components inside the vehicle to be heat-exchanged according to the thermal management method of each component inside the vehicle to be heat-exchanged.

[0060] The thermal management method for the vehicle provided by the present invention first obtains the current navigation information of the vehicle and the driving habit information of the driver, then determines the thermal management method for at least one component inside the vehicle according to the navigation information and the driving habit information of the driver, and finally performs thermal management on all components inside the vehicle to be heat-exchanged according to the thermal management method of each component inside the vehicle to be heat-exchanged. This application performs different thermal management under different thermal management methods corresponding to different driving situations, solves the problems of single thermal management method and heat supply utilization rate, thereby improving the overall vehicle driving range and optimizing the overall vehicle energy consumption. Compared with mechanical heat supply, it fully considers the driving situation and can ensure that the components inside the vehicle maintain the optimal working temperature.

[0061] In the embodiment of the present application, the passenger compartment is a "seat" device for carrying passengers or drivers of the car. The passenger compartment may include processing functions, such as a smart cockpit of a car, and the present application does not impose any restrictions on this.

[0062] The battery is the driving energy source of the vehicle. The battery output voltage is low at low temperatures and the electricity conversion efficiency is low. When driving the car, the battery power is transmitted to the motor to supply the motor drive.

[0063] In a specific implementation of the present application, the navigation information may come from a user terminal that forms a network connection (eg, Bluetooth) with the vehicle, such as a navigation program on a mobile phone, or from a navigation program on a vehicle-mounted terminal, and the present application does not impose any restrictions on this.

[0064] In a specific implementation of the present application, the driving habit information can be obtained by recording the driver's historical driving information, which may include acceleration and deceleration conditions of each road section, etc., which will not be elaborated in this application. The driving habit information includes the driver's historical driving operations corresponding to various types of road conditions and / or historical navigation information. For example, in the driver's past driving records, when the green light countdown appears at the A three-way intersection, the driver's acceleration times are 30 times and the deceleration times are 3 times. Based on the above historical driving operations (i.e., corresponding to the green light countdown road conditions at the three-way intersection), it can be judged that the driver is likely to accelerate under the green light countdown road conditions at the three-way intersection.

[0065] Road conditions include all conditions during driving, such as rain, congestion, uphill and downhill. Driving operations include acceleration, deceleration, braking, turning, neutral gear, turning on the air conditioner, opening the sunroof, etc., which will not be elaborated in this application.

[0066] In some possible implementations, the thermal management method of at least one interior component of the vehicle is determined based on the navigation information and the driving habit information of the driver, such as Figure 2 As shown, including:

[0067] S21: Determine the driver's current driving operation according to the navigation information and the driving habit information.

[0068] It can be understood that, based on the navigation information and driving habit information, the present application can roughly deduce the possible driving behaviors of the driver under the current road conditions and road sections, such as acceleration, deceleration or constant speed.

[0069] In specific implementation, acceleration and deceleration correspond to the drive control of the motor. Acceleration requires the battery to increase its output power in a short period of time. Similarly, deceleration corresponds to a short-term reduction in the battery's output power. This shows that driving behavior directly determines the working conditions of the battery and motor.

[0070] S22: Determine the vehicle speed of the current vehicle under the driving behavior according to the driving operation.

[0071] In some possible implementation manners, through the driving operation and in combination with the current vehicle speed in the navigation, it is possible to predict the corresponding vehicle speed if the determined driving behavior is followed. Therefore, the motor power corresponding to the determined driving behavior can be calculated.

[0072] It can be seen that in this embodiment, by combining historical data to predict the driving behavior, the motor power and battery parameters at the next moment can be known, and thus heat supply preparation can be made in advance.

[0073] S23: Determine the heat management method for the at least one vehicle interior component based on the vehicle speed and the current temperature of each vehicle interior component to be heat-exchanged.

[0074] In some possible implementation manners, since the vehicle speed at the next moment or the next time period is considered, the power parameters of all heat-generating devices at the next moment or the next time period can be determined, so as to determine whether sufficient heat can be generated. When sufficient heat is generated, the current temperature of each vehicle interior component to be heat-exchanged can be considered, and then compared with the preset optimal temperature. The heat supply can be allocated according to the difference between the current temperature of each vehicle interior component to be heat-exchanged and the optimal temperature, and the temperature of each vehicle interior component to be heat-exchanged can be adjusted to the optimal.

[0075] In some possible implementation manners, the heating requirements of passengers can be considered based on driving habits. For example, when it is known that when the temperature is appropriate, passengers generally close the windows and turn on the vehicle air conditioner for ventilation after driving for 10 minutes, and generally step on the accelerator pedal with a relatively large amplitude when accelerating. At this time, by combining these data, it can be judged that the parameters such as the battery power and motor power required by the vehicle next. Then, the current battery and occupant compartment temperatures can be defined in combination with driving habits. In this implementation manner, the vehicle interior components include the battery and the occupant compartment, and the control method further includes: determining the heating requirement information of the current battery and the crew compartment based on the driving habit information, the temperature of the battery, and the temperature of the occupant compartment;

[0076] Specifically, in this implementation manner, the heat management of all vehicle interior components to be heat-exchanged according to the heat management method of each vehicle interior component to be heat-exchanged includes: controlling and distributing the heat generated by the motor under the determined heat management method according to the heat supply requirement information; after determining the heat distribution of the heat generated by the motor, performing heating control on the battery and the occupant compartment of the vehicle based on the heat distribution result.

[0077] In some possible embodiments of the present application, the specific driving behavior prediction process can be performed through frequency calculation, that is, searching for the driving behaviors of the driver in the same scenario from historical data, and counting the frequencies of each driving behavior, and taking the one with the highest frequency as the prediction result. In this way, on the one hand, the driving behavior of the driver can be accurately predicted, and on the other hand, the prediction process does not involve complex models and can quickly give the prediction result, which is particularly suitable for the application scenario of the present application.

[0078] In this embodiment, the determining of the current driving operation of the driver according to the navigation information and the driving habit information includes: extracting the current road condition information and vehicle speed information from the navigation information; searching for at least one driving operation corresponding to the current road condition information and the vehicle speed information in the driver habit information; extracting the driving operation with the highest occurrence frequency from all the found driving operations, and determining it as the current driving operation of the driver.

[0079] In some possible embodiments, a neural network model can be used to predict driving behavior. The neural network model makes predictions, and the predictions become more and more accurate after the neural network model converges, which is particularly applicable to vehicles with relatively high in-vehicle terminal processing performance.

[0080] In this embodiment, the determining of the current driving operation of the driver according to the navigation information and the driving habit information includes: extracting the current road condition information and vehicle speed information from the navigation information; inputting the road condition information and the vehicle speed information into a preset neural network model, and the neural network model outputs the driving operation; wherein the neural network model is trained using the driving habit information of the driver.

[0081] In some possible embodiments, the in-vehicle terminal can perform neural network processing by means of the processing performance of a Bluetooth-connected user terminal, such as a mobile phone. Specifically, a dedicated app program can be installed on the mobile phone side. The in-vehicle terminal can send data to the mobile phone terminal, and thus the app program on the mobile phone terminal performs processing and calculation to ensure timeliness.

[0082] In some possible embodiments of the present application, the neural network model of the present application can be established online or offline. The present application is not limited thereto. Further, the neural network model of the present application can be an Adaptive Linear Neuron (Adaline), a Convection Neural Network Model (CPN), a Self-Organizing Map Neural Network Model (SOM), a Hopfield neural network, etc. The present application does not limit this.

[0083] In some possible embodiments of the present application, the present application uses an SVM (Support Vector Machine) to train the neural network model, and the driving behavior can be judged through the facial expression recognition neural network model.

[0084] In some possible embodiments of the present application, during training, the historical scene feature vector can be first marked with driving behaviors, and then the input of the model is defined as the historical scene feature vector, and the output is defined as the corresponding driving behavior. Through a large number of repeated trainings, a converged neural network model can be obtained.

[0085] In some possible embodiments of the present application, the heat management method can be specifically screened in combination with temperature. In this embodiment, the in-vehicle components to be heat-exchanged include a battery and a passenger compartment. The heat management methods include: electric drive active heat generation heating, thermistor heating, waste heat heating of the electric drive assembly, internal battery heating, and any combination of multiple of them, that is, two heating methods can be combined to form a composite heat supply.

[0086] The specific heat management method can be carried out through Figure 5 the architecture in. First Figure 5 shows the heat supply architecture of the present application, integrating a drive assembly, a battery pack, and a heat pump system. Among them, the drive assembly (13) is connected in series with the Chiller (6) through a proportional three-way valve (5), and the battery pack (7) is connected in parallel with the electric drive assembly through a first solenoid valve (9) and a second solenoid valve (10) to realize waste heat heating of the electric drive to the battery pack and the heat pump system. At the same time, the electric drive assembly and the battery pack can be cooled through the Chiller. The heat pump system absorbs the heat of the electric drive assembly through the WCC heat exchanger (24) and the Chiller, and uses the air-heating PTC (26) for assistance to jointly heat the passenger compartment.

[0087] In some possible embodiments, when using the waste heat of the electric drive assembly for heating, the heat pump system and the battery pack absorb the heat of the electric drive assembly at the same time. By monitoring the water temperature at the inlet of the battery pack, the opening of the first expansion valve is controlled to control the heat absorption capacity of the heat pump system. At the same time, the air-heating PTC is used for assistance to improve the heating capacity of the passenger compartment.

[0088] In specific use, the electric drive active heat generation heating, thermistor heating, waste heat heating of the electric drive assembly, and internal battery heating are realized in the following ways: (Please briefly describe).

[0089] In certain embodiments, the in-vehicle components to be heat-exchanged include a battery and a passenger compartment. Determining the heat management method for the at least one in-vehicle component based on the vehicle speed of the whole vehicle and the current temperature of each in-vehicle component to be heat-exchanged includes: based on a set speed threshold and a plurality of set temperature thresholds, combining the vehicle speed of the whole vehicle and the current temperature of each in-vehicle component to be heat-exchanged, respectively determining the heat management methods for the battery and the passenger compartment. In this embodiment, by combining the speed threshold and the set temperature threshold, heat management control can be carried out in different situations.

[0090] In achievable embodiments, the thermal management methods include: electric drive active heat generation heating, thermistor heating, waste heat heating of the electric drive assembly, internal battery heating, and combinations of any of the above. The multiple set temperature thresholds include a first set temperature threshold, a second set temperature threshold, a third set temperature threshold, and a fourth set temperature threshold. Based on the set speed threshold and the multiple set temperature thresholds, and in combination with the vehicle speed and the current temperature of each vehicle interior component to be heat-exchanged, determining the thermal management methods for the battery and the passenger compartment respectively includes:

[0091] If the current temperature of the battery is higher than the first set temperature threshold, then use the waste heat of the electric drive assembly to heat the battery; if the current temperature of the battery is lower than the first set temperature threshold, determine whether the current vehicle speed is lower than the speed threshold. If it is lower and the current temperature of the battery is not lower than the second set temperature threshold and lower than the third set temperature threshold, then use a thermal management method that combines electric drive active heat generation and thermistor heating to heat the battery. If it is lower and the current temperature of the battery is lower than the second set temperature threshold, then use the waste heat of the electric drive assembly to heat it. If it is higher, then use the thermal management method of thermistor heating to heat the battery; if the current vehicle speed is lower than the speed threshold, and at the same time the current temperature of the battery is not lower than the third set temperature threshold and lower than the fourth set temperature threshold, then use the thermal management method of internal battery heating to heat the battery; if the current temperature of the battery is not lower than the fourth set temperature threshold, then use a heat pump to recover the waste heat of the battery and heat the passenger compartment.

[0092] As Figure 3 shown, the first set temperature threshold is -13°C, the speed threshold is 40 KM / h, the second set temperature threshold is -10°C, the third set temperature threshold is 20°C, and the fourth set temperature threshold is 25°C.

[0093] In specific applications, if the current temperature of the battery is higher than -13°C, then use the waste heat of the electric drive assembly to heat the battery; if the current temperature of the battery is lower than -13°C, determine whether the current vehicle speed is lower than the speed threshold. If it is lower and the current temperature of the battery is not lower than -10°C and lower than 20°C, then use a thermal management method that combines electric drive active heat generation and thermistor heating to heat the battery. If it is lower and the current temperature of the battery is lower than -10°C, then use the waste heat of the electric drive assembly to heat it. If it is higher, then use the thermal management method of thermistor heating to heat the battery; if the current vehicle speed is lower than the speed threshold, and at the same time the current temperature of the battery is not lower than 20°C and lower than 25°C, then use the thermal management method of internal battery heating to heat the battery; if the current temperature of the battery is not lower than 25°C, then use a heat pump to recover the waste heat of the battery and heat the passenger compartment.

[0094] In some other possible embodiments of the present application, the heat management mode of the passenger compartment can be adjusted considering road conditions and driving behavior. The vehicle interior components to be heat-exchanged include the battery and the passenger compartment. The heat management modes include: air heating, electric drive active heat generation heating, thermistor heating, waste heat heating of the electric drive assembly, internal battery heating, and any combination of multiple thereof. Specifically, the vehicle interior components to be heat-exchanged include the passenger compartment. Determining the heat management mode of at least one vehicle interior component based on the vehicle speed and the current temperature of each vehicle interior component to be heat-exchanged includes: determining the heat management mode of the passenger compartment based on multiple set temperature differences, in combination with the vehicle road conditions, driving habit information, and the current temperature of the passenger compartment.

[0095] More specifically, in an achievable embodiment, the heat management modes include: electric drive active heat generation heating, thermistor heating, waste heat heating of the electric drive assembly, internal battery heating, and any combination of multiple thereof. The multiple set temperature thresholds include a first set temperature threshold, a second set temperature threshold, a third set temperature threshold, and a fourth set temperature threshold. Determining the heat management modes of the battery and the passenger compartment respectively based on the set speed threshold and the multiple set temperature thresholds, in combination with the vehicle speed and the current temperature of each vehicle interior component to be heat-exchanged, includes: judging whether the air conditioner in the passenger compartment is turned on. If it is turned on and the temperature difference between the current external environment and the temperature in the passenger compartment is not higher than the first set temperature difference, the air heating heat management mode is used to heat the passenger compartment. If it is not turned on, then according to the vehicle road conditions, driving operations, and the current climbing condition, it is determined whether the vehicle is in an accelerating state or a climbing state at present. If so, it is judged whether the temperature difference is not lower than the second set temperature difference. If so, the air conditioner is turned off, and after a set time period, it is judged whether the temperature difference is not lower than the third set temperature difference. If the temperature difference is not lower than the third set temperature difference, it returns to the step of determining whether the vehicle is in an accelerating state or a climbing state at present according to the vehicle road conditions, driving operations, and the current climbing condition. If the temperature difference is lower than the third set temperature difference, the thermistor heating heat management mode is used to supply heat to the passenger compartment. If the temperature difference is not lower than the fourth set temperature difference, the heat management mode of combining the electric drive active heat generation and the heat pump recovering the waste heat of the electric drive assembly is used to supply heat to the passenger compartment. Otherwise, the air heating method is used to supply heat to the passenger compartment. If the temperature difference is not lower than the fifth set temperature difference, the heat management mode of combining the waste heat heating of the electric drive assembly and the internal battery heating is used.

[0096] In specific applications, such as Figure 4As shown in the figure, first, it is determined whether the air conditioner in the passenger compartment is turned on.
