Aiming at the problems that the operation is inconvenient, the cost is high, the experience of man-machine interaction is high and traffic safety hidden danger is easy to generate when the number of the steering wheel keys is large in the background art, the application provides a multiplexing control method of the steering wheel keys, in the method, the control objects of the up key, the down key and/or the confirmation key of the steering wheel keys are determined by receiving a multiplexing switching instruction of the steering wheel keys, so that the triggering instruction executes corresponding control actions. According to the multiplexing control method for the steering wheel keys, three different functions are multiplexed on the steering wheel, so that the platform is applicable, the key arrangement of the steering wheel is reduced, the cost is reduced, the man-machine interaction experience is improved, and the safety performance is improved. Therefore, the problems that the operation is inconvenient, the cost is high, the man-machine interaction experience is reduced, and the traffic safety hidden trouble is easy to generate when the number of the steering wheel keys is large are solved.
Specifically, fig. 1 is a flow chart of a multiplexing control method for a steering wheel key according to an embodiment of the present application.
As shown in fig. 1, the multiplexing control method of the steering wheel key comprises the following steps:
in step S101, a multiplexing switching instruction of a steering wheel key is received.
Further, in one embodiment of the present application, receiving a multiplexing switch instruction of a steering wheel key includes: receiving a first multiplexing instruction generated when a HUD height adjusting soft switch of a head-up display is in an on state; or receiving a second multiplexing instruction generated when the HUD height adjustment soft switch is in a closed state and the instrument of the vehicle is not in the menu adjustment page; or receiving a third multiplexing instruction generated when the HUD height adjusting soft switch is in an off state and the instrument is in a menu adjusting page. Specifically, the design scheme of the steering wheel multiplexing adopted in the embodiment of the application includes a steering wheel up key, a down key and an OK key, namely a confirm key, and three different functions are multiplexed through the steering wheel keys, which are respectively: the upper and lower keys of the steering wheel multiplex HUD height adjusting function, the upper and lower keys of the steering wheel and the confirmation key multiplex instrument menu function, and the upper and lower keys of the steering wheel and the confirmation key multiplex vehicle-mounted multimedia function.
Further, as shown in fig. 2, the main control logic of the steering wheel key multiplexing function in the embodiment of the present application is that when the control object is a meter, the meter receives the up-down key signal of the steering wheel transmitted from the gateway and is implemented by the steering wheel key to control the meter; when the control object is a vehicle or HUD, the instrument sends a CAN (Controller Area Network ) signal to the vehicle or HUD.
Specifically, the instrument panel receives a multiplexing switching instruction of the steering wheel keys sent by the gateway through the CAN network cable, such as the five-way key of the multifunctional steering wheel instrument, the five-way key of the multifunctional steering wheel instrument and the confirmation of the five-way key of the multifunctional steering wheel instrument. Firstly, the instrument panel judges whether a current HUD height adjustment soft switch is opened to be in an on state, and if the current HUD height adjustment soft switch is in the on state, a first multiplexing instruction is generated; secondly, if the current HUD height adjustment soft switch is in a closed state and the instrument of the vehicle is in a menu adjustment page, a second multiplexing instruction is generated; and finally, if the current HUD height adjustment soft switch is in a closed state and the instrument is not in the menu adjustment page, generating a third multiplexing instruction to execute corresponding control.
In step S102, control objects of up, down, and/or confirm keys of the steering wheel key are determined according to the multiplexing switch instruction.
Further, in one 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 switch instruction includes: if the multiplexing switching instruction is a first multiplexing instruction, the control object of the up key, the down key and/or the 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 confirmation key of the steering wheel key is an instrument menu; if the multiplexing switching instruction is a third multiplexing instruction, the control object of the up key, the down key and/or the confirmation key of the steering wheel key is vehicle-mounted multimedia.
Specifically, when the multiplexing command of the vehicle key is the first multiplexing command, the instrument forwards the CAN signal to the HUD, namely, the control object of the up key, the down key and/or the confirmation key of the steering wheel key is a head-up display HUD; when the multiplexing switching instruction of the vehicle key is a second multiplexing instruction, the instrument automatically adjusts the menu page, namely, the control object of the up key, the down key and/or the confirmation key of the steering wheel key is an instrument menu; when the multiplexing switching instruction of the vehicle key is a third multiplexing instruction, the instrument forwards the steering wheel key signal to the vehicle machine, namely, the control object of the up key, the down key and/or the confirmation key of the steering wheel key is vehicle-mounted multimedia.
In step S103, the control object is controlled to execute the corresponding control action according to the triggering command of the up key, the down key and/or the confirm key.
Further, in an embodiment of the present application, controlling the control object to execute the corresponding control action according to the triggering instruction of the up key, the down key and/or the confirm 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 a meter menu, controlling the meter menu to enter the previous page according to the trigger instruction of the upper key, controlling the meter menu to return to the next page according to the trigger instruction of the lower key, and determining the currently selected menu item in the meter menu according to the trigger instruction of the confirmation key; when the control object is the vehicle-mounted multimedia, controlling the volume of the vehicle-mounted multimedia to be increased according to the triggering instruction of the key-up, controlling the volume of the vehicle-mounted multimedia to be reduced according to the triggering instruction of the key-down, and controlling the vehicle-mounted multimedia to be paused or played according to the triggering instruction of the confirmation key.
Specifically, when the instrument panel determines that the current HUD height adjustment soft switch is in an on state, the control object of the up key, the down key and/or the confirm key of the steering wheel key is the HUD. That is, when the control object is the HUD, the current height of the HUD is controlled to be increased according to the trigger instruction of the upper key of the steering wheel, and the current height of the HUD is controlled to be decreased according to the trigger instruction of the lower key of the steering wheel, that is, the gear of the HUD is adjusted upwards or downwards by one gear each time the upper key and the lower key are pressed, until the HUD reaches the highest gear or the lowest gear, and the HUD stops responding. The HUD height adjusting soft switch has two closing modes, namely, the HUD height adjusting interface of the vehicle exit machine and the HUD height adjusting soft switch which is manually closed.
Further, when the HUD height adjustment soft switch is in an off state and the meter of the vehicle is in a menu adjustment page, the control object of the up key, the down key and/or the confirm key of the steering wheel key is the meter menu. That is, when the control object is the instrument menu, the instrument receives the signal of the up-down key of the steering wheel to perform the up-down page turning function of the instrument menu, for example, the instrument menu is controlled to return to the previous page according to the trigger instruction of the up key, and the instrument menu is controlled to enter the next page according to the trigger instruction of the down key; when the instrument receives a short-press confirmation key of a steering wheel key, a menu item confirmation function is performed, and when the confirmation key is pressed for a long time, an instrument menu screenshot function is performed; when the instrument receives a short-press menu key of a steering wheel table, the instrument is opened or exited, the upper-level menu is returned, when the menu key is pressed for a long time, the instrument is returned to an initial interface, and the menu key is not pressed for a long time in the initial menu.
Further, when the HUD height adjustment soft switch is in an off state and the meter of the vehicle is not on the menu adjustment page, the control object of the up key, the down key and/or the confirm key of the steering wheel key is vehicle-mounted multimedia. That is, when the control object is the vehicle-mounted multimedia, the instrument forwards the received up-down key signal and the received confirmation key signal of the steering wheel key to the vehicle machine, and the vehicle machine adjusts the volume of the vehicle-mounted multimedia after receiving the up-down key signal, for example, controls the volume of the vehicle-mounted multimedia to be increased according to the trigger instruction of the up key, and controls the volume of the vehicle-mounted multimedia 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.
In summary, specific application information and schematic diagrams of the multiplexing functions, control objects, keys and icons of the steering wheel keys and the multiplexing keys of the steering wheel according to the embodiments of the present application are shown in table 1 and fig. 3, respectively:
TABLE 1
Figure BDA0003722506990000061
Figure BDA0003722506990000071
It should be noted that, since the priority of the meter for the control of the up and down keys of the steering wheel is determined as follows: the HUD height adjusting soft switch is more than the instrument menu page turning function is more than the vehicle-mounted multimedia volume adjusting function, so that when a user turns on the HUD height adjusting soft switch of the vehicle, the HUD height adjusting soft switch is only used for adjusting HUD height, and is not used for adjusting instrument menu page turning and steering wheel volume.
It should be noted that the instrument switches the instrument interface according to the related CAN signal input in the above table, the CAN signal corresponds to 1 when the key is pressed for a short time, 1 when the key is pressed for a long time, and the instrument judges whether the key is pressed for a long time or a short time according to the time 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 secondary interface of the instrument driving information displays whether to reset the driving information, receiving a driving information reset instruction sent by a user; 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, the user needs to send a driving information reset instruction to the instrument, when the instrument receives the reset instruction sent by the user, the second-level page of the driving information displays an option of whether to reset or not, if the user needs to reset, the user presses the confirmation key for resetting the driving information, and if the user does not need to reset, the user presses the confirmation key for continuing to execute the pause or play function of the vehicle-mounted audio multimedia.
Further, in an embodiment of the present application, the method for controlling multiplexing of steering wheel keys further includes: when the vehicle power down is detected, the actual state of the vehicle HUD height adjustment soft switch is saved.
Specifically, the setting signal of the HUD height-adjusting soft switch adopted in the embodiment of the present application is a periodic signal, the rising edge of 0-1 is used as an effective value, the signal is classified as an invalid value after three frames are triggered, the last state of the HUD is kept unchanged when the invalid value is obtained, the actual state value of the HUD height-adjusting soft switch when the vehicle is powered down is memorized through an instrument panel, and the display state of the HUD height-adjusting soft switch on the vehicle is displayed according to the signal value fed back by the instrument.
According to the multiplexing control method for the steering wheel keys, which is provided by the embodiment of the application, 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 corresponding control actions are triggered to execute by the triggering instruction. According to the multiplexing control method for the steering wheel keys, three different functions are multiplexed on the steering wheel, so that the platform is applicable, the key arrangement of the steering wheel is reduced, the cost is reduced, the man-machine interaction experience is improved, and the safety performance is improved. Therefore, the problems that the operation is inconvenient, the cost is high, the man-machine interaction experience is reduced, and the traffic safety hidden trouble is easy to generate when the number of the steering wheel keys is large are solved.
