Therefore, in the related art, when the vehicle body domain controller controls power supply and power failure of the vehicle, the power supply is limited to one-to-one power supply or power failure, the power supply mode is simple and rough, unreasonable, the accurate power failure to repair cannot be effectively met, the accurate power supply or power failure cannot be applied to different vehicle controllers, the requirement of a user on applying accurate switching to loads corresponding to different functions of the vehicle cannot be met, the utilization efficiency of vehicle electric energy is reduced, and the problems of vehicle battery loss and the like are aggravated.
Specifically, fig. 1 is a schematic flow chart of a power supply method after a whole vehicle is powered down according to an embodiment of the present application.
As shown in fig. 1, the power supply method after the whole vehicle is powered down comprises the following steps:
In step S101, a vehicle power-down request of a vehicle is received.
It can be understood that the vehicle power-down request of the vehicle in the embodiment of the present application includes, but is not limited to, a request generated by locking the vehicle after closing the door, clicking a one-button start button, clicking a one-button power-down button, screwing a key gear, and the like, so as to switch the vehicle power supply to the OFF gear.
The embodiment of the application can receive the whole vehicle power-down request of the vehicle, and judge whether the user has the relevant whole vehicle power-down request or not through the operation of the user on the vehicle, thereby receiving the corresponding request and further controlling the vehicle to perform the whole vehicle power-down action in the following steps.
In step S102, after controlling the power down of the vehicle based on the power down request of the whole vehicle, a function start request sent by the user based on the mobile terminal or the server is received.
It may be understood that in the embodiment of the present application, the vehicle power-down state may be a vehicle state in which all loads unrelated to the vehicle are turned off, and the function start request sent by the user may be a separate start instruction sent by the user for different vehicle functions.
In some embodiments, after the vehicle enters the OFF gear, a power-down request of the whole vehicle is received, and a part of systems of the vehicle, such as a chassis, power, audio and video systems, are disconnected, so that the complete closing of irrelevant loads after the whole vehicle is powered down is realized.
According to the embodiment of the application, after the vehicle power-down is controlled based on the vehicle power-down request, the function starting request sent by the user based on the mobile terminal or the server is received, so that the specific function required by the user is further determined, and a basis is provided for accurate power supply for the required function in the following steps.
In step S103, at least one associated load and/or at least one associated vehicle controller corresponding to the function turning-on request is identified and mapped onto the corresponding first power interface, so as to power up the at least one associated load and/or the at least one associated vehicle controller, and when the function turning-off request of the user is obtained, if the at least one associated load and/or the at least one associated vehicle controller corresponding to the function turning-off request is not in an activated state after the corresponding second power interface is turned off, the second power interface is turned off, and power supply is stopped.
It may be understood that, in the embodiment of the present application, the associated load and the associated vehicle controller corresponding to the function start request may be an on-board device capable of implementing the function request and an on-board facility for supplying power to the function, the first power interface may be a power interface for supplying power to the associated load and/or the associated vehicle controller corresponding to the function start request, and the second power interface may be a power interface for supplying power to the associated load and/or the associated vehicle controller corresponding to the function close request.
In some embodiments, after a vehicle identifies a function start request, it identifies a load and a controller associated with the function through a software model and maps the load and the controller to a corresponding power interface for supplying power to the function, and after the vehicle identifies a function shut-down request, it identifies the load and the controller associated with the function through the software model and shuts down the load and the controller associated with the function, if the load and the controller associated with the function are not in an active state after the load and the controller associated with the function are shut down, i.e. no other power supply request exists for the power interface, the power interface is shut down to enable, and power supply is stopped.
For example, after receiving the air conditioning heating instruction, the vehicle identifies an associated heating load and a fresh air transmission load of the air conditioning heating function through a software model, maps the associated heating load and the fresh air transmission load to a corresponding power interface for supplying power to the air conditioning heating function, applies enabling power to the power interface, closes the associated heating load and the fresh air transmission load after the user sends a closing request of the air conditioning heating function, detects that the power interface corresponding to the heating load and the fresh air transmission load is not in an activated state at this moment, judges that other power supply requests do not exist on the power interface, and stops supplying power to the power interface.
The embodiment of the application can identify at least one associated load and/or at least one associated vehicle controller corresponding to the function starting request, map the at least one associated load and/or the at least one associated vehicle controller to the corresponding first power interface to power up, stop power supply to the second power interface if the corresponding second power interface is not in an activated state after the function closing request of a user is executed, and realize accurate power up by maximally utilizing resources through specific identification and positioning to the power supply state of the power source, thereby reducing the power consumption of the vehicle and improving the energy saving level of the vehicle.
Optionally, in one embodiment of the present application, when acquiring the function closing request of the user, the method further includes: and if at least one associated load corresponding to the function closing request and/or the corresponding second power interface is in an activated state after at least one associated vehicle controller is closed, disabling closing and enabling the second power interface until the second power interface is not in the activated state.
It may be understood that, in the embodiment of the present application, the second power interface may be a power interface that supplies power to an associated load and/or an associated vehicle controller of a function corresponding to the function shutdown request, where the second power interface is not in an active state may mean that no vehicle device connected to the second power interface is in a power supply requirement state.
For example, after the vehicle recognizes the shutdown request for the function a, the vehicle recognizes and confirms the load and the controller associated with the function a, and shuts down the load and the controller associated with the function a, if the load and the controller associated with the function a are still in an active state after shutting down the load and the controller associated with the function a, it is indicated that there is a function B that needs to supply power to the power interface, at this time, shutdown enabling of the power interface is prohibited, so as to maintain the power supply requirement of the function B to be satisfied, until the function B is completed, the power interface is no longer in an active state, and at this time, power supply to the power interface is stopped.
When the function closing request of the user is obtained, if at least one associated load corresponding to the function closing request and/or a second power interface corresponding to the at least one associated vehicle controller are in an activated state after the function closing request is closed, the second power interface is forbidden to be closed and enabled until the second power interface is not in the activated state, so that the situation that the power supply requirements of other running functions cannot be met due to the closing of the power interfaces is avoided, the normal use of the user is influenced, the distinguishing capability of the vehicle for different energy consumption conditions is improved, and the use requirement of the user is met.
Optionally, in one embodiment of the present application, after powering up at least one associated load and/or at least one associated vehicle controller, the method further comprises: at the end of the execution of the at least one associated load and/or at least one associated vehicle controller function, a function shutdown request is generated.
It may be understood that, in the embodiment of the present application, the execution end state may be a state of the vehicle after completing the operation related to the instruction required by the user, and the function closing request generated by the vehicle may be a request sent by the vehicle to the user and including the instruction completion information and the function information related to the request closing.
For example, after the vehicle completes the instruction required by the user, the function execution of the vehicle controller is finished, at this time, instruction completion information is sent to the user mobile terminal, and the user is queried whether to finish the operation, if the user confirms the finish operation, the vehicle executes the relevant finish operation of the function.
According to the embodiment of the application, after the at least one associated load and/or the at least one associated vehicle controller are electrified, when the execution of the functions of the at least one associated load and/or the at least one associated vehicle controller is finished, the function closing request is generated, so that the ending process of the user instruction is accelerated, unnecessary electric quantity consumption is reduced, and the energy saving level of the vehicle is further improved.
Optionally, in one embodiment of the present application, after powering up at least one associated load and/or at least one associated vehicle controller, the method further comprises: and receiving a function closing request sent by a user based on the mobile terminal or the server.
It may be understood that, in the embodiment of the present application, the function closing request sent by the user may be an instruction related to the ending function execution process transmitted to the vehicle by the user, for example, the user may send an instruction for closing the required function to the vehicle through the APP end of the mobile phone, and the vehicle performs related ending operation on the required function after receiving the instruction of the user.
According to the embodiment of the application, after at least one associated load and/or at least one associated vehicle controller is electrified, the function closing request sent by the user based on the mobile terminal or the server is received, and the vehicle operation is executed based on the user intention, so that the actual requirement of the user is further met, and the man-machine interaction level of the vehicle is improved.
Optionally, in one embodiment of the present application, after powering up at least one associated load and/or at least one associated vehicle controller, the method further comprises: generating a power-on-wake signal for at least one associated load and/or at least one associated vehicle controller; and sending a power-on reminding signal to the mobile terminal or the server, and carrying out power-on reminding to the user.
It may be understood that, in the embodiment of the present application, the power-on reminding signal may be a communication signal including power-on operation information for the relevant function when the vehicle is turned on, and the power-on reminding signal for the user may be a reminding signal including power-on procedure starting information sent to the user by the mobile terminal or the server.
In the actual execution process, after the vehicle starts the relevant power-on operation of the required function, a reminding signal that the function is powered on is generated and sent to the user mobile terminal or the server, and power-on starting information is transmitted to the user so as to inform the user of the power-on process of the relevant function.
The embodiment of the application can generate the power-on reminding signal of at least one associated load and/or at least one associated vehicle controller, and send the power-on reminding signal to the mobile terminal or the server to carry out power-on reminding to the user, thereby synchronizing the relevant operation process of the vehicle to the user in real time, ensuring the information updating efficiency of the user and improving the intelligent interaction level of the vehicle.
The working of the embodiment of the present application will be described in detail with reference to fig. 2.
Step S201: the whole vehicle is powered down.
That is, the entire vehicle is powered down, including but not limited to locking the vehicle after closing the door, clicking a one-button start button, clicking a one-button power down button, turning a key gear, and the like, to switch the vehicle power to the OFF gear.
Step S202: the part load power is turned off.
That is, after the vehicle enters the OFF gear, the power supply of part of the systems including the chassis, the power, the video and audio system and the like can be disconnected by the domain controller, so that the complete closing of the irrelevant load after the whole vehicle is powered down is realized.
Step S203: the domain controller recognizes that the function request is on.
That is, when the mobile phone APP/cloud initiates a function request such as remote unlocking, remote windowing, remote opening of an air conditioner, remote photographing, etc., the domain controller recognizes the function request from the cloud and then performs power-on operation.
Step S204: the associated load power is turned on by the software model map.
That is, after the domain controller recognizes the corresponding function request, the domain controller recognizes the function-related load and the controller through the software model, maps the function-related load and the controller to the corresponding power interface, and enables the corresponding interface to be powered on. And accurate power-on is realized by maximally utilizing resources.
Step S205: the domain controller recognizes that the function requests to be turned off.
That is, when the function execution ends or the user actively turns off the function, the domain controller recognizes the function turn-off request.
Step S206: and judging whether the associated interface has other function requests to occupy, if so, executing the step S205, otherwise, executing the step S207.
That is, since the load following the same interface may have a situation that multiple functions are simultaneously requested to occupy, after the domain controller recognizes that a certain function is turned off, it is determined whether other functions are still requested to be in an active state, if so, the interface is not turned off, and step S205 is performed, and the next function turn-off request is waited, and if not, step S207 is performed.
Step S207: and turning off the load power supply.
That is, the function association mapping interface is turned off to enable, the power supply of the corresponding load is turned off, and the flow is ended.
According to the power supply method after the whole vehicle is powered down, after the whole vehicle is powered down based on the whole vehicle power down request, the power supply is stopped by receiving the function starting request sent by the user based on the mobile terminal or the server after the whole vehicle power down request is received, identifying at least one associated load and/or at least one associated vehicle controller corresponding to the function starting request and mapping the at least one associated load and/or the at least one associated vehicle controller onto the corresponding first power interface, and when the function closing request of the user is obtained, if the at least one associated load and/or the corresponding second power interface corresponding to the function closing request is not in an activated state after the at least one associated vehicle controller is closed, the second power interface is closed, the power supply is stopped, and the mapping relation between the required function and the associated load and the vehicle controller is identified according to different function requirements of the user, so that accurate power supply is implemented, the vehicle power utilization level is improved, the vehicle battery consumption is reduced, and the power supply is more intelligent. Therefore, in the related art, when the vehicle body domain controller controls power supply and power failure of the vehicle, the power supply is limited to one-to-one power supply or power failure, the power supply mode is simple and rough, unreasonable, the accurate power failure to repair cannot be effectively met, the accurate power supply or power failure cannot be applied to different vehicle controllers, the requirement of a user on applying accurate switching to loads corresponding to different functions of the vehicle cannot be met, the utilization efficiency of vehicle electric energy is reduced, and the problems of vehicle battery loss and the like are aggravated.
Next, a power supply device for a powered-down whole vehicle according to an embodiment of the present application will be described with reference to the accompanying drawings.

As shown in fig. 3, the power supply device 10 after the entire vehicle is powered down includes: the first receiving module 100, the second receiving module 200, and the power supply module 300.
