The thermal management of the vehicle means that the temperature and the thermal energy of components in the vehicle are managed, so that the components can be cooled and radiated or heated and kept warm in time, and the normal operation of the components of the vehicle can be ensured. Along with the mass popularization of new energy vehicles, the intellectualization of multi-power source cooling, power battery temperature control and passenger cabin temperature control, and the thermal management becomes more and more important for the energy control of the whole vehicle.
There are many types of vehicles on the market, and there are different vehicle powertrain configurations, vehicle launch strategies, vehicle costs, etc., which result in different thermal management requirements and targets for different vehicles. Therefore, different thermal management modes are required to meet the energy management objectives of the vehicle.
In the related art, when the vehicle is thermally managed, thermal management software is deployed on a controller in the vehicle, and different components are controlled by the thermal management software to perform operations such as heating up or cooling down. The thermal management software used by different vehicles is different, and each thermal management software uses different switching paths when switching thermal management modes. Wherein the switching path includes an order of actions and a kind of actions of all components involved in switching the vehicle to the target thermal management mode.
When the thermal management software is designed, different software models are needed, personalized switching path planning is carried out for each vehicle type, the universality is limited, and the cost is high. When there is a need to extend the thermal management modes of the vehicle, it is also necessary to redesign the thermal management software. Therefore, how to improve the commonality of thermal management software is a problem to be solved.
When a thermal management mode switching signal is received, mapping a first thermal management mode of a current vehicle control system and a target thermal management mode which is expected to be switched with a preset thermal management truth table respectively to obtain respective corresponding truth sequences.
The thermal management truth table comprises vehicle condition truth sequences corresponding to different thermal management modes respectively, the vehicle condition truth sequences comprise truth values corresponding to a plurality of vehicle conditions respectively, and the vehicle conditions refer to requirements which are required to be met by the working state of the controlled thermal management component when the thermal management modes are switched.
After determining the truth sequences respectively corresponding to the first thermal management mode and the target thermal management mode, a target switching path used for switching the vehicle control system from the first thermal management mode to the target thermal management mode may be determined from the candidate switching paths based on a correspondence between the truth sequences and the candidate switching paths.
The candidate switching paths comprise a plurality of paths which can be used when the thermal management modes are switched, each switching path plans the action sequence and the action types of a plurality of controlled components, and the vehicle control system controls the controlled components to carry out switching adjustment according to the content indicated by the target switching path so as to enable the vehicle to be switched from the first thermal management mode to the target thermal management mode.
When a plurality of components are controlled to act based on the target switching path, a truth sequence corresponding to the first thermal management mode and the target thermal management mode is used as an index condition, an action type corresponding to each component is found from a preset action table, the plurality of components are controlled to execute corresponding actions, and switching of the thermal management mode is successfully achieved until each component in the target switching path is executed.
For example, the thermal management truth table includes truth sequences corresponding to 12 thermal management modes, each truth sequence corresponding to 6 vehicle conditions. The candidate switching paths corresponding to the thermal management truth table include 50 switching paths.
When the received thermal management mode switch signal indicates that the vehicle control system is switched to the air-conditioning cooling mode, the vehicle condition truth sequence corresponding to the air-conditioning cooling mode in the thermal management truth table is the 2 nd truth sequence, that is, the air-conditioning cooling mode corresponds to the 2 nd thermal management mode in the thermal management truth table.
Optionally, the thermal management mode in which the vehicle control system is located at the current moment corresponds to the 1 st thermal management mode in the thermal management truth table, and the switching of the thermal management mode is from the 1 st thermal management mode to the 2 nd thermal management mode. Among the candidate switching paths, the path corresponding to the switching is the 4 th switching path.
The 4 th switching path involves various components and action types, and is arranged according to the sequence of executing actions, and the specific path content is as follows: the device comprises a switching valve, an expansion valve, a mixed gas heating and a compressor.
The above-described path indicates that the on-off valve in the vehicle is advanced and the expansion valve is operated again, so that the mixture is heated and then compressed by the compressor.
Wherein the action performed by each component may be obtained from a respective action table for each component. That is, the on-off valve, the expansion valve, and the compressor are respectively associated with the respective operation tables, which are two-dimensional tables, and when determining the type of operation to be performed by each component, the operation tables are indexed to the target execution operation using the first thermal management mode and the target thermal management mode as indexing conditions.
The operation indicated in the operation table of the on-off valve is open (total of three operation types: open/close/no operation), and the operation table of the expansion valve indicates that the expansion opening degree of the expansion valve is 30 (total of four opening types: 0 degree/30 degree/50 degree/no operation).
Then, the thermal management mode switching process of controlling the vehicle control system is as follows: after the on-off valve is opened, the expansion opening degree of the expansion valve is adjusted to 30 degrees, and the mixture is heated and compressed by the compressor.
In summary, the method provided by the application maps the first thermal management mode in which the vehicle control system is currently located and the target thermal management mode indicated by the thermal management mode switching signal with the thermal management truth table respectively, determines the truth sequences corresponding to the first thermal management mode and the target thermal management mode respectively, can determine the mode of switching the thermal management mode based on the truth sequences, and the working state transition mode required to be achieved by the controlled component in the thermal management mode switching process, so that the thermal management mode switching of the vehicle is realized, and the efficiency and convenience of thermal management are improved. The method has the advantages that various vehicle conditions in the thermal management truth table are used as indexes for describing the thermal management modes, the method can be suitable for different types of vehicles, and compared with a mode of designing different thermal management software for different types of vehicles to carry out thermal management, the method has universality and can save development cost and time.

FIG. 3 is a flowchart of a method for thermal management mode switching based on a target switching path and action table of a component according to an exemplary embodiment of the present application, including the following steps.
Step 310, a candidate switching path corresponding to the vehicle condition truth sequence is obtained.
The candidate switching paths include a plurality of thermal management mode switching paths, and the thermal management mode switching paths include types of actions performed by components controlled by the vehicle control system according to a preset sequence.
At step 320, a target switch path is determined from the candidate switch paths based on the first and second truth sequences.
Optionally, a correspondence exists between the vehicle condition truth sequence in the thermal management truth table and the candidate switching path, and the first truth sequence and the second truth sequence are two sequences in the vehicle condition truth sequence, and the target switching path is determined from the candidate switching path according to the correspondence.
For example, the first thermal management mode in which the vehicle control system is currently located is the target mode 0 in table 1, the target thermal management mode is the target mode 1 in table 1, and the corresponding target switching paths are as follows: "on-off valve 1, on-off valve 2, on-off valve 3, expansion valve 1, expansion valve 2, expansion valve 3, mixture, heat, compressor, complete".

The action table is a two-dimensional table, and the action table comprises the action type of a component controlled by the vehicle control system in the target switching path, and the corresponding relation between the first truth sequence and the second truth sequence.
In some embodiments, the target switching path only includes the types of all components that need to execute actions and the action types of some of the components, so that the specific actions executed by each component when performing the thermal management mode switching need to be determined based on the action table corresponding to each component by using the first truth sequence and the second truth sequence as index conditions.
Illustratively, the target handover path is as follows: "on-off valve 1, on-off valve 2, on-off valve 3, expansion valve 1, expansion valve 2, expansion valve 3, mixture, heat, compressor, complete".
Schematically, as shown in fig. 4, fig. 4 is a schematic diagram of an electronic switching valve mode switching action table.
Since the on-off valves 1, 2, and 3 are all electronic on-off valves, the operation table 400 shown in fig. 4 can be used for each of the on-off valves 1, 2, and 3.
Optionally, the first truth sequence includes a first mode number for indicating the first thermal management mode, where the first mode number corresponds to the sequence number of the target mode in table 1. The second truth sequence includes a target pattern number for indicating a target thermal management pattern, the first pattern number corresponding to the target pattern number in table 1.

For example, when the target mode number 420 is 1 and the first mode number 410 is 0, it indicates that the vehicle is switched from the target mode 0 to the target mode 1, and at this time, the type of operation of the on-off valve is determined as "0" in the operation table 400 using (0, 1) as an index condition.
The action table 400 relates to three action types, wherein when the value is 0, the on-off valve is closed, when the value is 1, the on-off valve is opened, and when the value is-1, the on-off valve does not execute action.
Therefore, when the thermal management mode is switched, the on-off valve 1, the on-off valve 2, and the on-off valve 3 execute the closing operation in order.
Schematically, as shown in fig. 5, fig. 5 is a schematic diagram of an action table for mode switching of the electronic expansion valve.
Since the expansion valves 1, 2, and 3 are electronic expansion valves, the operation table 500 shown in fig. 5 can be used for each of the expansion valves 1, 2, and 3.
Optionally, the first truth sequence includes a first mode number for indicating the first thermal management mode, where the first mode number corresponds to the sequence number of the target mode in table 1. The second truth sequence includes a target pattern number for indicating a target thermal management pattern, the first pattern number corresponding to the target pattern number in table 1.
In fig. 5, the thermal management modes corresponding to the vehicle switching mode before and after the vehicle switching mode are represented by two-dimensional parameters (target mode number 520, first mode number 510), and the operation type of the expansion valve is determined in the operation table 500 as an index condition.
For example, when the target mode number 520 is 1 and the first mode number 510 is 0, it indicates that the vehicle is switched from the target mode 0 to the target mode 1, and at this time, the operation type of the expansion valve is determined as "50" in the operation table 500 using (0, 1) as an index condition.
The operation table 500 refers to two operation types, and when the value is greater than 0, the expansion valve is expanded, and the corresponding value is the expansion valve opening, and when the value is-1, the expansion valve does not execute the operation.
Therefore, when the thermal management mode is switched, the expansion valve 1, the expansion valve 2, and the expansion valve 3 sequentially perform the expansion operation with the opening degree of 50.
The workflow of the component when performing the thermal management mode switching will be described by taking the compressor involved in the target switching path as an example.

The vehicle conditions 600 corresponding to the truth sequence include: and judging the state of the compressor, diagnosing and judging the fault state of the compressor, and determining the states of the system, the passenger cabin and the battery.

Step 340, the components controlled by the vehicle control system in the target switching path are controlled based on the action table to execute the corresponding actions, and the vehicle control system is switched to the target thermal management mode.
Since the target switching path includes a plurality of components, the execution actions and the order of each component are different, and thus each component is controlled to execute the corresponding actions in the action table in the order indicated in the target switching path.
Optionally, acquiring an action table corresponding to an ith component controlled by a vehicle control system in the target switching path; wherein i is a positive integer.
Optionally, the target switching path includes n components, n is a positive integer, and i is a positive integer not exceeding n.
