and S102, determining a requirement threshold value of the thermal management operation matched with the working state based on the obtained working state of the whole vehicle.
The corresponding heat requirements of the whole vehicle are different when the whole vehicle runs in different working states, and the heat management operation required to be executed by the whole vehicle heat management system is different, so that the corresponding requirement threshold can be read when the running state is identified by presetting the corresponding requirement threshold according to different working states, and the heat management operation of the whole vehicle heat management system can be determined according to the requirement threshold.

The method includes the steps of judging whether an interference phenomenon exists in a plurality of kinds of thermal management operations existing at the same time in an operation state to be configured, for example, a first kind of thermal management operation and a second kind of thermal management operation need to be executed at the same time, wherein a control valve A in the first kind of thermal management operation needs to be configured in a closed state, and a control valve A in the second kind of thermal management operation needs to be configured in an open state.

and regenerating the control information according to the updated demand information.

In some embodiments, in the presence of an interference phenomenon, the operating state to be configured is adjusted according to a preset adjustment manner to eliminate the interference phenomenon, which may be implemented as follows:
one possible way is to: determining a plurality of thermal management operations corresponding to a plurality of running states to be configured as requirements to be adjusted under the condition that an interference phenomenon exists; calculating a difference value between a working condition parameter in the demand to be adjusted and a corresponding demand threshold value; and determining the requirement to be adjusted with the largest difference as the thermal management operation to be executed, and canceling other thermal management operations in the requirement to be adjusted so as to eliminate the interference phenomenon.
In the embodiment, the difference between the actual working condition temperature and the requirement threshold is detected to judge the execution priority of the corresponding thermal management operation according to the difference, the higher the difference is, the higher the priority is, so that the refrigerant adjusting device is controlled to execute the demand to be adjusted with the highest priority, and the demand to be adjusted with the low execution priority is cancelled, so that the interference phenomenon is eliminated.
Another possible way is: determining the execution priority of various thermal management operations corresponding to a plurality of running states to be configured respectively under the condition that an interference phenomenon exists; and sequentially configuring the refrigerant adjusting devices to corresponding operating states according to the execution priority so as to eliminate the interference phenomenon.
In the embodiment, when a plurality of thermal management operations need to be executed simultaneously, the priority of each thermal management operation is preset to control the refrigerant adjusting device to execute in sequence according to the sequence from high to low, so that the normal operation of the thermal management system is ensured, a plurality of thermal management requirements can be met, and the vehicle can be in a more stable and safe working state.
Referring to fig. 3, a flowchart illustrating steps of an embodiment of a control method of a vehicle thermal management system according to the present invention is shown, which may specifically include the following steps:

And step S316, receiving a feedback signal fed back by the independent controller according to the configuration instruction.
In step S318, if the feedback signal is an enable signal, the corresponding demand information is determined as the second control information.
In step S320, if the feedback signal is a non-enable signal, the corresponding requirement information is deleted to regenerate the second control information.
If part of the refrigerant adjusting devices and the heat management operation executed by the refrigerant adjusting devices are controlled by a non-vehicle controller, namely controlled by an independent controller, a feedback signal sent by the independent controller is obtained through communication interaction between the vehicle controller and the independent controller, and whether the refrigerant adjusting devices controlled by the independent controller can be added into the vehicle control or not is determined according to the feedback signal so as to reduce the probability of system operation abnormity.
In step S322, the operation state of the refrigerant adjusting device is configured according to the first control information and the second control information.
In the embodiment, the vehicle controller is required to send a state and demand request to the independent controller and the non-automatic control accessory, when the independent controller feeds back the demand enable and the accessory state conforms to the demand, the demand information is kept, since the logic determination of all controllers is not necessarily consistent, if the feedback of the independent controller is not enabled or the status of the individual accessories is contrary to the requirement, the requirement information is updated according to the heat pipe requirements of the whole vehicle and the status of each requirement enabling item and accessory, the actual control information is obtained, the various requirements of the whole vehicle are checked one by one through the code form, can ensure that no omission or missing of function requirements exists, individual function codes can never occur in the real vehicle working condition, which leads to strategy redundancy, but the dead cycle can not be entered due to identification omission in the strategy execution process, and the safe operation of the whole vehicle is ensured.

As shown in fig. 7, the demand code of the demand information includes three stages, the first stage corresponds to a battery heat exchange circuit, the second stage corresponds to an air conditioning circuit, and the third stage corresponds to a power system heat exchange circuit, where the power system heat exchange circuit includes a vehicle-mounted charger, a voltage converter, a power distribution unit, an MCU, a driving motor, and the like.
For example, the cooling requirement of the battery is judged, the temperature of the battery is higher than 35 ℃ under the driving working condition of the vehicle, the battery needs to be cooled, and the temperature of the battery is higher than 25 ℃ under the quick charging working condition, and other judgment principles are similar.
The generation process of the code 2 is slightly different from that of the code 1, because the vehicle control unit can send a request for starting and a request for switching the accessory state to other controllers according to the code 1, for example, the vehicle control unit can send a battery cooling request to the air conditioning system, after the air conditioning system is enabled by feedback, the battery cooling request can be finally established, that is, the code representing the battery cooling request in the code 2 can be the same as the code 1, and if the air conditioning system is not enabled by feedback of the battery cooling request, the battery cooling request is determined to be the battery cooling-free request in the generation process of the code 2. Other decisions are analogized. And the final code 2 is the requirement that all controllers of the whole vehicle can realize together. And thus performs the subsequent processes.
