Description
Technical Field
The present invention relates to the field of electronic control technologies, and in particular, to a method and an apparatus for controlling a key, and a computer-readable storage medium.
Background
In the prior art, in order to save physical space, different key functions can be triggered by a long press or a short press for the same physical button, wherein the long press and the short press both trigger a press (DWON) event and a lift (UP) event of the corresponding function respectively by a press operation and a lift operation of the key.
When the method is specifically applied to a scene of controlling a vehicle, after a press-DOWN action of a user (no matter long press or short press) is recognized, a vehicle machine distributes a short press-DOWN event (MODE _ KEY _ DOWN) of a short press corresponding to a function, and waits for a short press-UP event (MODE _ KEY _ UP) corresponding to the short press-DOWN event to end the process, but when the press-DOWN duration of the user exceeds a preset time, the vehicle machine system distributes another long press-DOWN event (VOICE _ KEY _ DOWN) corresponding to a long press function, at the moment, if the user lifts UP a button, the vehicle machine distributes a long press-UP event (VOICE _ KEY _ UP), the function corresponding to the long press KEY is triggered, but in the process of triggering the long press of the corresponding function by the vehicle machine, the short press-DOWN event of the system is always in the process.
For example, a "MODE switch" button (MODE) on the steering wheel switches the media source played in short time, and wakes up the voice assistant function in long time.
The user prepares to execute the operation of waking up the voice assistant according to MODE, and the execution sequence is as follows:
1. press MODE button.
At this time, the in-vehicle system distributes a MODE _ KEY _ DOWN event once.
2. Within one second after the MODE key is pressed.
At this time, the vehicle system distributes a VOICE _ KEY _ DOWN event again.
3. The MODE key is raised.
At this time, the car machine system distributes a VOICE _ KEY _ UP event.
And the vehicle-mounted machine system finishes long-press key event distribution.
As can be seen from the above, the system has executed one more MODE _ KEY _ DOWN event, which is an invalid event, and there is no MODE _ KEY _ UP event ending.
In the prior art, when the function corresponding to the long-press key is started, a short-press event needs to be started, which wastes system resources on one hand, and on the other hand, the instability of the car machine system may be caused because no corresponding short-press lift event is matched.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the invention thereto.
Example 1
The present embodiment provides a method for controlling a key, as shown in fig. 1, the method includes the following steps:
Specifically, the specific lifting signal and the specific pressing signal can be selected according to actual conditions, for example, for a touch key, the touch signal is used as the pressing signal and the lifting signal; for another example, for the pressing type key, the pressure signal is used as the pressing signal and the lifting signal.
It should be understood that the above is only an example of the types of the lift-off signal and the push-down signal, and should not be a limitation to the present embodiment.
In a preferred embodiment, as shown in fig. 2, step 101 specifically includes the following steps:
and step 1013, acquiring the timing time of the timer and taking the timing time as the interval time.
In the embodiment, for the same key, the timer is started when the pressing signal is received, and the timer is closed when the lifting signal is received, so that the interval time between the pressing and the lifting of the target key can be accurately acquired by a simple timer timing mode.
And 102, acquiring a key function corresponding to the interval time.
In this embodiment, a corresponding relationship between the interval time and the key function is preset, and in step 102, the corresponding key function may be matched from the preset corresponding relationship according to the obtained interval time.
It should be understood that, in the present embodiment, which key functions are specifically included, and which key function is specifically matched with which interval or which interval, may be selected according to actual requirements.
In a specific embodiment, the key function includes at least one of a sound source switching function, a voice assistant starting function, a window opening and closing function, a system testing function and a system restarting function. In other embodiments, other key functions may be included, which is not limited in this embodiment.
In this embodiment, for the same key, different key functions can be obtained according to different time intervals, so that the function multiplexing of the same key is realized.
And 103, distributing a pressing event and a lifting event corresponding to the key function to trigger the key function to run.
In this embodiment, after receiving the lifting signal of the target key, the pressing event and the lifting event of the key function corresponding to the interval time are distributed to trigger the operation of the corresponding key function, so that on one hand, it is ensured that a plurality of key pressing events are not distributed in the process of one function triggering, thereby saving the resources of the system, and on the other hand, it is also ensured that the distributed pressing events are matched with the corresponding lifting events, thereby improving the stability of the system.
In a preferred embodiment, step 103 specifically includes the following steps:
distributing a pressing event corresponding to the key function;
after a preset time, a lift-up event corresponding to the key function is automatically distributed to trigger the operation of the key function.
In this embodiment, the lift-up event may be automatically distributed after a preset time elapses after the distribution of the press-down event, so that the operation of the corresponding key function may be triggered, and the lift-up event may be automatically distributed without other operations on the key, thereby further enhancing the stability of the system while ensuring the execution efficiency of the key function.
In a preferred embodiment, the control method further comprises the steps of:
and if the uplifting signal of the target key is not received within a preset time range after the pressing signal of the target key is received, generating key fault information.
In a specific embodiment, the control method is applied to a scenario of vehicle function control, but it should be understood that in other embodiments, the control method may also be applied to other scenarios, and the embodiment is not limited thereto.
In a specific embodiment, the target key is a physical key disposed on the vehicle, but it should be understood that in other embodiments, the target key is also a physical key, a virtual key, etc., disposed on other devices, and the embodiment is not limited thereto.
For a better understanding of the present embodiment, the following describes the present embodiment through two specific scenarios:
scene one:
assuming that the target key is specifically a "MODE switching" key (i.e., a MODE key) of the vehicle, in this scenario, multiplexing of two vehicle functions needs to be implemented, and when the interval time is less than 1s (second), the corresponding key function is a short-press function, and may specifically be a wake-up voice assistant function; when the interval time is longer than 1s, the corresponding key function is a long-press function, and may be a mode switching function specifically.
As shown in fig. 3, step 101 is executed first, a press signal is received when the MODE KEY is pressed, so as to start a timer, if the timer still does not receive a lift signal of the MODE KEY at the end of timing 1s, step 102 is executed to acquire the corresponding KEY function as a wake-UP VOICE assistant function, step 103 is executed again, a press event (VOICE _ KEY _ DOWN) corresponding to the VOICE assistant function is distributed, and a lift event (VOICE _ KEY _ UP) corresponding to the wake-UP VOICE assistant function is automatically distributed after 100ms (milliseconds), so as to trigger the wake-UP VOICE assistant function.
In step 101, if the timer receives a MODE KEY UP signal within 1s of time, step 102 is executed to obtain the corresponding KEY function as the sound source switching function, and then step 103 is executed to automatically distribute a DOWN event (MODE _ KEY _ DOWN) corresponding to the sound source switching function and a UP event (MODE _ KEY _ UP) corresponding to the sound source switching function after 100ms, thereby triggering the voice switching function of the vehicle.
Scene two:
assuming that the target key is specifically a MODE switching key (i.e., a MODE key) of the vehicle, in this scenario, multiplexing of at least four vehicle functions needs to be implemented, and when the interval time is less than 1s, the corresponding key function is a function of a MODE key in a conventional vehicle, i.e., a function of switching a sound source; when the interval time is greater than or equal to 1s and less than 2s, the corresponding key function is the function of a VOICE key in the traditional vehicle, namely the function of waking up a VOICE assistant; when the interval time is greater than or equal to 2s and less than 3s, the corresponding key function is the function of a WINDOW key in a traditional vehicle, namely the function of opening a vehicle WINDOW; when the interval time is greater than or equal to X seconds and less than X +1 seconds, the corresponding key function is a function of a REBOOT key in a conventional vehicle, that is, a function of restarting the vehicle machine, it should be understood that X in this embodiment may select a specific value according to an actual requirement, for example, X is 4 in a specific implementation, and in this embodiment, more key functions of the vehicle may also be extended according to the actual requirement.
As shown in fig. 4, step 101 is first executed, a MODE key is pressed, a press signal is received, a timer is started, a MODE key is lifted, a lift signal is received, and an interval N is calculated. Then, step 102 is executed, and when N is smaller than 1, the corresponding key function is a sound source switching function; when N is more than or equal to 1 and less than 2, the corresponding key function is a function of waking up the voice assistant; when N is more than or equal to 2 and less than 3, the corresponding key function is a window opening function; and when the N is more than or equal to the X and less than the X +1, the corresponding key function is a vehicle restarting machine function. Then, step 103 is executed to trigger the corresponding function to run.
In step 102, if N exceeds 3X seconds and the key-up signal is not received, it is determined that the key is possibly damaged, the timer is turned off, and a prompt signal may be further sent to prompt a relevant person to perform processing.
