The following describes a steering wheel key multiplexing control method, a steering wheel key multiplexing control device, a vehicle, and a storage medium according to an embodiment of the present application with reference to the drawings. In the method, control objects of an upper key, a lower key and/or a confirmation key of the steering wheel key are determined by receiving a multiplexing switching instruction of the steering wheel key, so that the instruction is triggered to execute a corresponding control action. According to the multiplexing control method for the steering wheel buttons, three different functions are multiplexed on the steering wheel, so that the platform application is realized, the button arrangement of the steering wheel is reduced, the cost is reduced, the human-computer interaction experience is improved, and the safety performance is improved. Therefore, the problems that when the number of the steering wheel keys is large, operation is inconvenient, cost is high, human-computer interaction is reduced, experience is high, and traffic safety hidden dangers are prone to being caused are solved.
Specifically, fig. 1 is a schematic flowchart of a multiplexing control method for steering wheel keys according to an embodiment of the present disclosure.
As shown in fig. 1, the multiplexing control method for steering wheel keys includes the following steps:
in step S101, a multiplexing switching instruction of the steering wheel key is received.
Further, in an embodiment of the present application, receiving a multiplexing switching instruction of a steering wheel key includes: receiving a first multiplexing instruction generated when a HUD height adjusting soft switch of the head-up display is in an open state; or receiving a second multiplexing instruction generated when the HUD height adjusting soft switch is in a closed state and the instrument of the vehicle is not in the menu adjusting page; or receiving a third multiplexing instruction generated when the HUD height adjusting soft switch is in a closed state and the instrument is in a menu adjusting page. Specifically, the design scheme for multiplexing the steering wheel adopted in the embodiment of the present application includes an up key, a down key and an OK key, i.e., a confirmation key, of the steering wheel, and three different functions are multiplexed through the keys of the steering wheel, which are respectively: the upper and lower keys of the steering wheel multiplex the HUD height adjusting function, the upper and lower keys of the steering wheel multiplex the instrument menu function with the confirmation key, and the upper and lower keys of the steering wheel multiplex the vehicle-mounted multimedia function with the confirmation key.
Further, as shown in fig. 2, the main control logic of the steering wheel key multiplexing function of the embodiment of the present application is an instrument controller, and when a control object is an instrument, the instrument receives a steering wheel up-down key signal transmitted from a gateway and is implemented by controlling the instrument by using the steering wheel keys; when the control object is a car machine or a HUD, the instrument sends a CAN (Controller Area Network) signal to the car machine or the HUD for realization.
Specifically, the instrument panel receives a steering wheel key multiplexing switching instruction sent by the gateway through the CAN network cable, such as the confirmation of the up key, the down key and the five-way key of the multifunctional steering wheel instrument. Firstly, judging whether a current HUD height adjusting soft switch is turned on or not by an instrument panel, and if the current HUD height adjusting soft switch is turned on, generating a first multiplexing instruction; secondly, if the current HUD height adjusting soft switch is in a closed state and an instrument of the vehicle is in a menu adjusting page, generating a second multiplexing instruction; and finally, if the current HUD height adjusting soft switch is in a closed state and the instrument is not in a menu adjusting page, generating a third multiplexing instruction to execute corresponding control.
In step S102, the control targets of the up key, the down key, and/or the enter key of the steering wheel key are determined according to the multiplexing switching instruction.
Further, in an embodiment of the present application, determining a control object of an up key, a down key and/or a confirm key of a steering wheel key according to a multiplexing switching instruction includes: if the multiplexing switching instruction is a first multiplexing instruction, the control object of an upper key, a lower key and/or a confirmation key of the steering wheel key is a head-up display (HUD); if the multiplexing switching instruction is a second multiplexing instruction, the control object of the up key, the down key and/or the enter key of the steering wheel key is an instrument menu; and if the multiplexing switching instruction is a third multiplexing instruction, controlling objects of an upper key, a lower key and/or a confirmation key of the steering wheel key are vehicle-mounted multimedia.
Specifically, when the vehicle key multiplexing instruction is a first multiplexing instruction, the instrument forwards the CAN signal to the HUD, that is, the control object of the up key, the down key and/or the enter key of the steering wheel key is the head-up display HUD; when the vehicle key multiplexing switching instruction is a second multiplexing instruction, the instrument automatically adjusts menu pages, namely the control objects of an upper key, a lower key and/or a confirmation key of a steering wheel key are instrument menus; when the vehicle key multiplexing switching instruction is a third multiplexing instruction, the instrument forwards the steering wheel key signal to the vehicle machine, namely, the control objects of the up key, the down key and/or the confirmation key of the steering wheel key are vehicle-mounted multimedia.
In step S103, the control object is controlled to execute the corresponding control action according to the trigger command of the up key, the down key and/or the enter key.
Further, in an embodiment of the present application, controlling the control object to execute a corresponding control action according to a triggering instruction of the up key, the down key and/or the enter key includes: when the control object is the HUD, controlling the current height of the HUD to rise according to the trigger instruction of the upper key, and controlling the current height of the HUD to fall according to the trigger instruction of the lower key; when the control object is an instrument menu, controlling the instrument menu to enter a previous page according to a trigger instruction of an upper key, controlling the instrument menu to return to a next page according to a trigger instruction of a lower key, and determining a currently selected menu item in the instrument menu according to a trigger instruction of a confirmation key; when the control object is the vehicle-mounted multimedia, the volume of the vehicle-mounted multimedia is controlled to be increased according to the trigger instruction of the upper key, the volume of the vehicle-mounted multimedia is controlled to be decreased according to the trigger instruction of the lower key, and the vehicle-mounted multimedia is controlled to be paused or played according to the trigger instruction of the confirmation key.
Specifically, when the instrument panel judges that the current HUD height adjusting soft switch is in an on state, the control object of the up key, the down key and/or the enter key of the steering wheel key is the HUD. That is to say, when the control object is a HUD, the current height of the HUD is controlled to increase according to the trigger instruction of the upper key of the steering wheel, and the current height of the HUD is controlled to decrease according to the trigger instruction of the lower key of the steering wheel, that is, each time the upper key and the lower key are pressed, the gear of the HUD is adjusted upwards or downwards for one gear, and until the highest gear or the lowest gear is reached, the HUD stops responding. Wherein, the soft switch of HUD altitude mixture control has two kinds of modes of closing, withdraws from the HUD altitude mixture control interface of car machine promptly and closes the soft switch of HUD altitude mixture control manually.
Further, when the HUD height adjustment soft switch is in an off state and the vehicle instrument is on the menu adjustment page, the control object of the up key, the down key and/or the enter key of the steering wheel key at this time is the instrument menu. That is, when the control object is an instrument menu, the instrument receives a signal of an up-down key of a steering wheel to perform the function of turning up and down the page of the instrument menu, if the instrument menu is controlled to return to the previous page according to a trigger instruction of the up key, the instrument menu is controlled to enter the next page according to a trigger instruction of the down key; when the meter receives a short press confirmation key of a steering wheel key, a menu item confirmation function is carried out, and when the confirmation key is pressed for a long time, a meter menu screenshot function is carried out; when the meter receives a short press of a menu key of a steering wheel case key, the meter menu is opened or exited and a previous-level menu is returned, when the menu key is pressed for a long time, the meter initial interface is returned, and the long press of the menu key in the initial menu does not correspond.
Further, when the HUD height adjusting soft switch is in an off state and the instrument of the vehicle is not in the menu adjusting page, the control object of the up key, the down key and/or the confirmation key of the steering wheel key is vehicle-mounted multimedia. That is to say, when the control object is the vehicle-mounted multimedia, the instrument forwards the received up-down key signal and the confirmation key signal of the steering wheel key to the vehicle machine, and the vehicle machine performs volume adjustment on the vehicle-mounted multimedia after receiving the up-down key signal, if the volume of the vehicle-mounted multimedia is controlled to be increased according to the trigger instruction of the up key, the volume of the vehicle-mounted multimedia is controlled to be decreased according to the trigger instruction of the down key; and after receiving the confirmation key signal, controlling the vehicle-mounted multimedia to pause or play.
To sum up, the specific application information about the multiplexing function, the control object, the keys and the icons of the steering wheel keys and the schematic diagram of the steering wheel multiplexing keys in the embodiment of the present application are respectively shown in table 1 and fig. 3:
TABLE 1
Figure BDA0003722506990000061
Figure BDA0003722506990000071
It should be noted that, since the priority of the meter for the up-down key control of the steering wheel is determined as follows: HUD altitude mixture control soft switch > instrument menu turns over page function > vehicle-mounted multimedia volume control function, consequently, when the soft switch of HUD altitude mixture control that the user opened the car machine, HUD degree regulation use is only done to its function, does not turn over the page and steering wheel volume control use of instrument menu.
It should be noted that the instrument switches the instrument interface according to the input of the relevant CAN signal in the table above, the CAN signal is sent to 1 when the key is pressed for a short time, and the CAN signal is sent to 1 when the key is pressed for a long time, and the instrument judges whether the key is pressed for a long time or pressed for a short time according to the time length triggered by the CAN signal.
Further, in an embodiment of the present application, the method for controlling multiplexing of steering wheel keys further includes: when the driving information is reset or not is displayed on a secondary interface of the instrument running information, a driving information resetting instruction sent by a user is received; and if the driving information resetting instruction is received, resetting the driving information.
Specifically, when the control object is an instrument menu, if the user wants to reset the driving information, a driving information resetting instruction needs to be sent to the instrument, when the instrument receives the resetting instruction sent by the user, the instrument displays an option of whether the driving information is reset on a secondary page of the driving information, if the user needs to reset, the driving information is reset by short pressing a confirmation key, and if the user does not need to reset, the vehicle-mounted audio multimedia pause or play function is continuously executed by short pressing the confirmation key.
Further, in an embodiment of the present application, the above method for multiplexing steering wheel keys further includes: when detecting that the vehicle is down, save the actual state of vehicle HUD altitude mixture control soft switch.
Specifically, the signal that sets up of the soft switch of HUD altitude mixture control that this application embodiment adopted is periodic type signal to 0-1 rising edge is the RMS, returns to the invalid value after triggering the three frames, keeps HUD last state unchangeable during the invalid value, and HUD's altitude mixture control soft switch's actual state value when the vehicle is down electric through the panel board memory, and the demonstration state of the soft switch of HUD altitude mixture control on the car machine is according to the signal value of instrument feedback and is done the demonstration.
According to the multiplexing control method of the steering wheel keys, the control objects of the up key, the down key and/or the confirmation key of the steering wheel keys are determined by receiving the multiplexing switching instruction of the steering wheel keys, so that the instruction is triggered to execute the corresponding control action. According to the multiplexing control method for the steering wheel buttons, three different functions are multiplexed on the steering wheel, so that the platform application is realized, the button arrangement of the steering wheel is reduced, the cost is reduced, the human-computer interaction experience is improved, and the safety performance is improved. Therefore, the problems that when the number of the steering wheel keys is large, operation is inconvenient, cost is high, human-computer interaction is reduced, experience is high, and traffic safety hidden dangers are prone to being caused are solved.
