Detailed Description
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
The following description of the embodiments of the present invention will be provided with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the present invention. All other embodiments, which can be made by one of ordinary skill in the art without undue burden on the person of ordinary skill in the art based on the embodiments of the present invention, are intended to be within the scope of the present application.
Referring to fig. 1, fig. 1 shows a flowchart of a function control method according to an embodiment of the present invention, where the method is applied to a vehicle-mounted host, the function control method may include the following steps:
The instruction input by the user is an instruction for indicating to trigger a scene mode corresponding to the instruction, and the instruction can comprise a click operation instruction and a voice instruction; the user may input a command corresponding to a certain mode by clicking an icon or button corresponding to the mode in the screen of the vehicle-mounted host, or may input a voice command corresponding to the scene mode to the vehicle-mounted host by using voice.
It should be noted that, a plurality of scene modes corresponding to different scenes may be preset in a vehicle-mounted host (HUT, head Unit), and the different scene modes correspond to different instructions, specifically, a plurality of different scene modes corresponding to different scenes may be preset in the vehicle-mounted host, the different scene modes respectively correspond to different instructions, the scene modes and the instructions are in a one-to-one correspondence relationship, and a user may determine the scene mode corresponding to the instruction by inputting the instruction in the vehicle-mounted host.
In the embodiment of the invention, after a user inputs a command to the vehicle-mounted host, the vehicle-mounted host responds to the command input by the user to determine a scene mode corresponding to the command from a plurality of scene modes. For example, the scene mode may be a rest mode, and the user may input an instruction corresponding to the rest mode by clicking an icon corresponding to the rest mode in the screen of the vehicle-mounted host, or may input an instruction corresponding to the rest mode by clicking a button corresponding to the rest mode in the vehicle-mounted host, or may input an instruction corresponding to the rest mode by inputting a keyword corresponding to the rest mode through voice.
In an embodiment of the present invention, one scene mode may be associated with one or more vehicle functions, and determining at least one vehicle function associated with the scene mode corresponding to the instruction input by the user may be determining all vehicle functions associated with the scene mode. The binding relationship between the first scene mode and the vehicle function corresponding to the first scene mode is that the first scene mode and the vehicle function corresponding to the first scene mode are associated when the first scene mode is newly added, so that the vehicle function associated with the first scene mode can be determined after the user inputs the first instruction corresponding to the first scene mode.
The at least one vehicle function associated with the scene mode may be one, a plurality of, or all of functions that the current vehicle has and that can be controlled by the vehicle terminal controller.
For example, when the scene mode is the rest mode, the vehicle functions bound to the scene mode may include a whole vehicle power-on control function, an air-conditioning control function, and a lamp control function.
Specifically, in the early design stage, a control signal corresponding to the vehicle function may be set for each vehicle function of the vehicle, for example, an enable control signal of the keyless entry function may be peenable=0x0 (enable), and a disable control signal of the keyless entry function may be peenable=0x1 (disable).
When associating a scene mode with a vehicle function, a control signal of each vehicle function corresponding to the scene mode may be set at the same time, for example, in the case that the scene mode is a power saving mode, the control signal of the lamp control function associated with the scene mode may specifically be a disable control signal; in the case where the scene mode is the night driving mode, the control signal of the lamp control function associated with the scene mode may specifically be an enable control signal. Of course, the control signals may include, but are not limited to, an enable control signal and a disable control signal, and may further set an adjustment signal corresponding to a vehicle function according to actual situations, for example, in a case where the vehicle function is an air conditioning function, the control signal corresponding to the vehicle function may specifically be an air conditioning temperature adjustment control signal, a cooling mode control signal, a heating mode control signal, and the like.
It should be noted that, in any one of different scene modes, the control signal corresponding to each vehicle function associated with the scene mode is preset according to the scene mode, and after determining the scene mode corresponding to the instruction input by the user and determining at least one vehicle function associated with the scene mode, the preset control signal corresponding to each vehicle function associated with the scene mode may be acquired.
In the embodiment of the invention, the terminal controller is a controller for controlling different vehicle functions of the vehicle. The terminal controller may be a number of different terminal controllers corresponding to a number of different vehicle functions. For example, a seat controller controls a seat heating function; the vehicle body controller controls external light.
Specifically, after acquiring a control signal corresponding to each vehicle function associated with the scene mode, the in-vehicle host may send the control signal to a terminal controller corresponding to the vehicle function through a CAN (Controller Area Network ) network. Wherein the CAN network is a broadcast type network, so that a control signal transmitted through the CAN network CAN be received by all the terminal controllers in the CAN network in the vehicle, but a terminal controller receives and performs a control operation corresponding to the control signal if and only if the terminal controller has logic related to the control signal, that is, if the vehicle function corresponding to the control signal is a vehicle function controlled by the terminal controller.
In the embodiment of the invention, the terminal controller corresponding to the vehicle function is a terminal controller in the vehicle for controlling the function of the vehicle. After the control signal is sent to the terminal controller corresponding to the vehicle function, the control signal is used for notifying the terminal controller to control the vehicle function controlled by the terminal controller according to the information indicated by the control signal.
When there are a plurality of vehicle functions associated with one of the scene modes in the in-vehicle host computer, a plurality of different control signals corresponding to the plurality of different vehicle functions associated with the scene mode may be acquired at the same time, and the plurality of different control signals may be sent to different terminal controllers corresponding to the plurality of different functions, respectively, and the plurality of different terminal controllers corresponding to the plurality of different functions may be notified to control the plurality of different functions through the plurality of different control signals. For example, when the vehicle function associated with the first scene mode includes a first vehicle function and a second vehicle function, a first control signal corresponding to the first vehicle function and a second control signal corresponding to the second vehicle function associated with the first scene mode may be acquired simultaneously, and the first control signal and the second control signal may be respectively transmitted to a terminal controller corresponding to the first vehicle function and a terminal controller corresponding to the second vehicle function, and the terminal controller corresponding to the first vehicle function and the terminal controller corresponding to the second vehicle function may be notified to control the first vehicle function and the second vehicle function, respectively, through the first control signal and the second control signal.
Referring to fig. 2, fig. 2 shows a flowchart of another function control method according to an embodiment of the present invention. The function control method may include the steps of:
This step may be described in detail with reference to step 110, and will not be described here again.
This step is described in detail with reference to step 120 and will not be described in detail here.
The state information of the vehicle function is the state information of the vehicle function associated with a certain scene mode when the whole vehicle is in the scene mode. For example, in the case where the first scene mode is a car wash mode, the user wishes to disable the keyless entry function of the vehicle, preventing frequent triggering of actions of unlocking and locking the door during wiping of the door handle. Thus, the vehicle function associated with the first scene mode may be a keyless entry function, and then the state information of the vehicle function associated with the first scene mode may specifically be a disablement of the keyless entry function, specifically, the state information of the keyless entry function corresponding to the carwash mode is a disablement of the keyless entry function when the vehicle is in the carwash mode.
In the embodiment of the invention, when defining at least one vehicle function associated with a certain scene mode, the specific states of all vehicle functions associated with the scene mode are also determined when the vehicle is in the scene mode; thus, after determining at least one vehicle function associated with the scene mode according to the scene mode, the state information of all vehicle functions associated with the scene mode may be correspondingly acquired, for step 240 to further acquire a control signal corresponding to the state information of the vehicle function according to the state information of the vehicle function.
In the embodiment of the present invention, the control signal is a control signal corresponding to the state information of the vehicle function, which is identifiable by the terminal controller and further acquired based on the state information of the vehicle function acquired in step 230, so that the terminal controller corresponding to the vehicle function can accurately identify the control signal after receiving the control signal, and control the vehicle function according to the control signal. Therefore, after the user inputs the instruction to the vehicle-mounted host computer to trigger the scene mode corresponding to the instruction, the vehicle function associated with the scene mode is in a state corresponding to the state information of the vehicle function, and normal starting of the scene mode corresponding to the instruction input by the user is ensured.
For example, in the case that the first scene mode is the car wash mode, the vehicle function associated with the first scene mode may be a keyless entry function, and then the state information of the vehicle function corresponding to the first scene mode may be disabled for the vehicle function, specifically, when the vehicle is in the car wash mode, the state information of the keyless entry function corresponding to the car wash mode is disabled for the keyless entry function. According to the disabled state information of the keyless entry function, the acquired control signal corresponding to the disabled state information of the keyless entry function may specifically be 0x1.
In the embodiment of the invention, the preset message format is a splicing format of the data message predefined according to the CAN protocol. The specific positions of the control signals of the vehicle functions associated with the scene modes in the data message may be defined in advance, for example, the positions of the control signals of all the vehicle functions associated with the first scene mode in the data message may be defined in advance.
The preset message format may include a specific position of a preset control signal corresponding to all vehicle functions associated with a certain scene mode in the data message, and after the terminal controller receives the data message, the terminal controller may determine, according to the specific position of the preset control signal corresponding to all vehicle functions associated with the scene mode in the preset message format in the data message, the vehicle function corresponding to the control signal.
For example, when the vehicle function associated with the first scene mode includes a first vehicle function and a second vehicle function, a position of the first control signal of the first vehicle function associated with the first scene mode in the data packet may be defined as a position 1, and bytes 0-4 in the corresponding data packet are used for placing the first control signal corresponding to the first vehicle function; the position of the second control signal of the second vehicle function associated with the first scene mode in the data message is defined as position 2, corresponding to the 5 th-10 th byte in the data message, for placing the second control signal corresponding to the second vehicle function. After the on-board host acquires the first control signal of the first vehicle function associated with the first scene mode, the first control signal may be spliced at a predefined position 1 in the data packet, and the second control signal may be spliced at a predefined position 2 in the data packet. After the terminal controller receives the data message, in the case that the first vehicle function corresponding to the position 1 is determined to be the vehicle function controlled by the terminal controller, the terminal controller may receive a first control signal from the position 1 and control the first vehicle function according to the first signal; after the terminal controller receives the data message, if it is determined that the first vehicle function corresponding to the position 1 is not the function controlled by the terminal controller, the first control signal at the position 1 is ignored and is not processed.
Of course, if the number of the vehicle functions associated with the first scene mode is large, or if the number of the control signal occupation bytes corresponding to the vehicle functions associated with the first scene mode is large, if the total bytes of all the control signals corresponding to the state information of all the vehicle functions associated with the first scene mode exceeds the data length of one data message, the control signals corresponding to the state information of all the vehicle functions associated with the first scene mode may be sent to the terminal controller through two or more data messages.
And 260, sending the data message to a terminal controller corresponding to the vehicle function.
In the embodiment of the invention, after the control signal is generated into the data message corresponding to the control signal according to the preset message format, the vehicle-mounted host CAN send the data message to the CAN network, and the control signal in the data message is sent to the terminal controller corresponding to the vehicle function through the CAN network.
Specifically, a data packet including a control signal sent through the CAN network may be received by all the terminal controllers in the CAN network in the vehicle, but if and only if a certain terminal controller has logic related to the control signal, that is, if the vehicle function corresponding to the control signal is a vehicle function controlled by the terminal controller, the terminal controller receives the control signal from the data packet and performs a control operation corresponding to the control signal.
Optionally, before step 110 or step 210, the following steps may be further included:
step 101, determining at least one vehicle function corresponding to the scene mode.
Specifically, when a scene mode is newly added in the vehicle-mounted host, all vehicle functions related to the scene mode can be determined first, for example, when the scene mode which needs to be newly added is a car washing mode, the vehicle functions related to the scene mode can be keyless entry functions; when the newly added scene mode is required to be a valet mode, the vehicle function related to the scene mode can be a related function related to personal data of the user. After determining the vehicle function associated with the scene mode, determining the vehicle function associated with the scene mode as at least one vehicle function corresponding to the scene mode.
Step 102, associating each vehicle function with the scene mode, and determining state information of the vehicle function corresponding to the scene mode.
Specifically, after determining at least one vehicle function associated with a scene in step 101, a scene mode may be associated with each determined vehicle function, and status information of the vehicle function in the scene mode may be determined, so that after determining the vehicle function associated with the scene mode, the status information of each vehicle function associated with the scene mode may be acquired.
In the embodiment of the invention, when a scene mode is newly added in a vehicle-mounted host, at least one vehicle function related to the scene mode needing to be newly added is firstly determined, then each vehicle function related to the scene mode needing to be newly added is associated with the scene mode, and the state information of each vehicle function corresponding to the scene mode is determined. Therefore, after the scene mode is newly added, when the user triggers the scene mode to be started by inputting an instruction corresponding to the scene mode into the vehicle-mounted host, each vehicle function associated with the scene mode can be in a state corresponding to the state information of the vehicle function, and the normal starting of the scene mode is ensured.
Referring to fig. 3, fig. 3 shows a flowchart of yet another function control method according to an embodiment of the present invention, which is applied to a terminal controller, the function control method may include the steps of:
The control signals are control signals corresponding to vehicle functions acquired by the vehicle-mounted host computer; the vehicle function is at least one vehicle function associated with a scene mode; the scene mode is determined by the vehicle-mounted host computer and corresponds to an instruction input by a user.
Specifically, the terminal controller may receive, through the CAN network, a control signal sent by the vehicle-mounted host to the CAN network. Because the CAN network is a broadcast type network, control signals sent by the CAN network CAN be received by all terminal controllers in the CAN network in the vehicle. Specifically, when the terminal controller that is not corresponding to the vehicle function receives the control signal, the terminal controller may determine that the vehicle function corresponding to the signal is not the vehicle function controlled by the terminal controller according to the control signal, and ignore the control signal; the terminal controller corresponding to the vehicle function receives and performs a control operation of the vehicle function corresponding to the control signal if and only if the terminal controller receives the control signal.
Specifically, after the terminal controller corresponding to the vehicle function receives the control signal corresponding to the vehicle function sent by the vehicle-mounted host, the terminal controller may control the vehicle function controlled by the terminal controller according to the information indicated by the control signal. For example, when the control signal corresponding to the vehicle function is 0x0, the terminal controller corresponding to the vehicle function controls the vehicle function to be enabled; when the control signal corresponding to the vehicle function is 0x1, the terminal controller corresponding to the vehicle function controls the vehicle function to be disabled.
Optionally, step 310 may specifically include the following sub-steps:
and a substep 311 of receiving a data message corresponding to the control signal.
The data message is generated by the control signal according to a preset message format and corresponds to the control signal.
In the embodiment of the present invention, the terminal controllers of the vehicle may include a plurality of terminal controllers corresponding to a certain vehicle function, and the terminal controller is one of the plurality of terminal controllers. The terminal controller CAN receive a data message corresponding to the control signal sent by the vehicle-mounted host through the CAN network. The data message comprises control signals corresponding to vehicle functions.
And a sub-step 312 of determining a vehicle function corresponding to the control signal in the data message according to a preset message format.
Specifically, after any terminal controller of the vehicle receives the data message, determining the vehicle function corresponding to the position of the control signal in the data message according to a predefined preset message format.
