Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a car start method according to an embodiment of the present invention. The vehicle starting method of the embodiment comprises the following steps:
s101: and acquiring an instruction for starting the system, and judging whether the external equipment exists.
In this embodiment, the system is a system on a vehicle platform, and the external device is a usb disk with an LED lamp, and in other embodiments, the external device is an SD card, a mobile hard disk, or other storage devices that can be loaded on the vehicle platform.
In a specific implementation scenario, the vehicle platform is a vehicle platform of an automobile, and the external device is a usb flash disk with an LED lamp. A user inputs an instruction for starting the system to the vehicle platform system, and the system judges whether a USB flash disk with an LED lamp connected with the system exists or not through a peripheral driver after acquiring the instruction.
In the implementation scenario, before acquiring an instruction for starting the system, the state information of the running application program needs to be acquired and stored when the system is closed last time, and the peripheral driver flag is set as the second peripheral driver flag by enabling the peripheral service, specifically, a user inputs an instruction for closing the system to the system on the automobile, and after receiving the instruction, the system acquires and stores the application program running in the system and information on whether the application program is in a state of running the external device, and further, when receiving the closing instruction, the system sets the peripheral driver flag as the second peripheral driver flag by enabling the peripheral service and stores the flag in the system.
In this embodiment, the second external driving flag is false, and in other embodiments, the second external driving flag may be another flag that can be recognized and stored by the system, which is not limited herein.
In the implementation scenario, the program being run by the system may be multimedia, radio, desktop, map, battery management, and other software that can run in the system. The system only needs to acquire and store the application program that is running when the instruction to close the system is acquired and the information of whether the application program is in the state of running the external device, which is not limited here.
In other implementation scenarios, the user may also directly set the time for loading the external device in the system and store the information in the system.
S102: and if the external equipment exists, determining the time for setting the first peripheral driving mark for the external equipment according to the pre-stored information.
In a specific implementation scenario, the car platform is an automobile platform, the external device is a usb flash disk with an LED lamp, the first external driver is marked as true, and the second external driver is marked as false. And if the enabling peripheral service reads the mark of the first peripheral drive mark true, the action of loading the external equipment is executed, and if the enabling peripheral service reads the mark of the second peripheral drive mark false, the action of loading the external equipment is not executed. And the system judges that the external equipment exists through the peripheral driver, and reads the pre-stored second set driving mark through the peripheral driver. Since the second peripheral driver is marked false, the system does not load the peripheral first. And after the enabling peripheral service is started, the enabling peripheral service determines the time for setting the first peripheral driving mark true according to the pre-stored information. The pre-stored information comprises state information of the application program when the system is closed last time, wherein the state information comprises whether the application program is in an operating state when the system is closed last time, and whether the application program operates the external device when the application program is in the operating state. Specifically, if the pre-stored information is information that the application program is in a state of running the external device when the system is closed last time, the peripheral service is enabled to modify the pre-stored second peripheral drive flag false into the first peripheral drive flag true and store the modified first peripheral drive flag true when the peripheral service is started. For example, when the system is turned off last time, the running program is a multimedia playing program, and the program is in a state of running the external device, so that the peripheral service modifies the pre-stored second peripheral driver flag false into the first peripheral driver flag true and stores the modified first peripheral driver flag true when being started.
In another specific implementation scenario, the car platform is an automobile platform, the external device is a usb flash disk with an LED lamp, the first external driver is marked as true, and the second external driver is marked as false. And if the enabling peripheral service reads the mark of the first peripheral drive mark true, the action of loading the external equipment is executed, and if the enabling peripheral service reads the mark of the second peripheral drive mark false, the action of loading the external equipment is not executed. And the system judges that the external equipment exists through the peripheral driver, and reads the pre-stored second set driving mark through the peripheral driver. Since the second peripheral driver is marked false, the system does not load the peripheral first. After the enabling peripheral service is started, the enabling peripheral service determines the time for setting the first peripheral driving mark true according to pre-stored information, wherein the pre-stored information comprises state information of an application program when the system is closed last time, the state information comprises whether the application program is in a running state when the system is closed last time, and whether the application program runs the external device when the application program is in the running state. Specifically, if the pre-stored information is information that the application program is in a state of not running the external device when the system is closed last time, after the desktop display of the vehicle is completed, the enabling peripheral service modifies the pre-stored second peripheral drive flag false into the first peripheral drive flag true and stores the modified first peripheral drive flag true. For example, when the system is turned off last time, the running program is a radio, the program is in a state where the external device is not running, and the enabling peripheral service modifies the pre-stored second peripheral driver flag false into the first peripheral driver flag true and stores the modified first peripheral driver flag true after the system is normal and the desktop display is completed.
In this embodiment, the first peripheral driving flag is set to true, and in other embodiments, the first peripheral driving flag may be another flag that can be recognized by the system and distinguished and stored from the second peripheral driving flag, which is not limited herein.
In other implementation scenarios, if the pre-stored information includes the external device loading time set by the user, the enabling peripheral service may directly modify the pre-stored second external drive flag false into the first external drive flag true according to the set time and store the modified first external drive flag true.
Further, if the system judges that no external device exists through the peripheral driver, the system directly starts the system and related programs on the system according to a default sequence.
S103: and reading the first peripheral driving mark and loading the external equipment.
In a specific implementation scenario, the car platform is an automobile platform, the external device is a usb flash disk with an LED lamp, the first external driver is marked as true, and the second external driver is marked as false. Enabling the peripheral service to modify a prestored second peripheral driving mark false into a first peripheral driving mark true, calling a peripheral driving through an enabling peripheral interface to detect whether external equipment exists, reading the peripheral driving mark again through the peripheral driving by the system, loading a USB flash disk with an LED lamp after determining that the peripheral driving mark is the first peripheral driving mark true, and flashing the LED lamp when the USB flash disk is loaded.
In the above embodiment, when the instruction to start the system is obtained, if the pre-stored information is two kinds of information, namely, the state that the application program is running the external device when the system is turned off last time and the state that the application program is not running the external device when the system is turned off last time, when the same system loads the usb disk with the LED lamp, the latter delays the loading time of the former by more than 100ms, that is, the time taken by the two to flash the LED lamp of the usb disk for the first time from the instruction to start the system is not the same, and the latter is at least 100ms more than the former.
Different from the situation of the prior art, the method and the system firstly judge whether the external equipment exists or not when the instruction for starting the system is obtained, enable the peripheral service to determine the time for setting the first peripheral driving mark for the external equipment according to the pre-stored information when the external equipment exists, and load the external equipment according to the first peripheral driving mark. According to the invention, when the vehicle machine is started, the external equipment is not directly detected and loaded, but the time for loading the external equipment is determined according to the pre-stored information, so that the starting time of the vehicle machine is effectively shortened, and the user experience is improved.
Based on the same inventive concept, the present invention further provides a vehicle-mounted device system, please refer to fig. 2, and fig. 2 is a schematic structural diagram of an embodiment of the vehicle-mounted device system of the present invention. The car machine system of the embodiment comprises the following devices:
the communication circuit 21, the processor 22, and the memory 23, wherein the processor 22 is coupled to the communication circuit 21 and the memory 23, respectively, the communication circuit 21 is configured to obtain and transmit an instruction, and the memory 23 is configured to store a first peripheral driving flag, a second peripheral driving flag, and a computer program executed by the processor 22. When the processor executes the computer program, the following vehicle-mounted device starting method is realized: acquiring a command for starting a system, and judging whether external equipment exists or not; if the external equipment exists, determining the time for setting a first peripheral driving mark for the external equipment according to the pre-stored information; and reading the first peripheral driving mark and loading the external equipment.
In this embodiment, the in-vehicle system is a system on the in-vehicle platform, the external device is a usb disk with an LED lamp, and in other embodiments, the external device is an SD card, a mobile hard disk, or other storage devices that can be loaded on the in-vehicle platform.
In a specific implementation scenario, the car platform is a car platform of an automobile, and the external device is a usb disk with an LED lamp. A user inputs an instruction for starting the system through the communication circuit 21, and the processor 22 judges whether a USB flash disk with an LED lamp connected with the system exists through the peripheral drive after acquiring the instruction.
In the implementation scenario described above, before acquiring the instruction to start the system, the processor 22 needs to acquire the state information of the running application program when the system is turned off last time, and store the state information in the memory 23. The processor 22 further sets the peripheral driving flag to be the second peripheral driving flag by enabling the peripheral service, specifically, the user inputs an instruction to turn off the system to the processor 22 in the automobile through the communication circuit 21, after receiving the instruction, the processor 22 acquires and stores the application program being run by the system and the information of whether the application program is in the state of running the external device, and further, when receiving the turn-off instruction, the processor 22 sets the peripheral driving flag to be the second peripheral driving flag by enabling the peripheral service and stores the flag in the memory 23.
In this embodiment, the second external driving flag is false, and in other embodiments, the second external driving flag may be another flag that can be recognized and stored by the system, which is not limited herein.
In the implementation scenario, the program being run by the system may be multimedia, radio, desktop, map, battery management, and other software that can run in the system. The processor 22 only needs to acquire and store the application program that is running in the system when the instruction to close the system is acquired and information on whether the application program is in a state of running the external device, which is not limited herein.
In other implementations, the user may also set the time to load the external device directly through the communication circuit 21 and store this information in the memory 23.
In a specific implementation scenario, the car platform is an automobile platform, the external device is a usb flash disk with an LED lamp, the first external driver is marked as true, and the second external driver is marked as false. And if the enabling peripheral service reads the mark of the first peripheral drive mark true, the action of loading the external equipment is executed, and if the enabling peripheral service reads the mark of the second peripheral drive mark false, the action of loading the external equipment is not executed. The processor 22 judges that the external device exists through the peripheral driver, and reads the second driving flag pre-stored in the memory 23 through the peripheral driver. Since the second peripheral driver flag is false, processor 22 does not load the peripheral first. And after the enabling peripheral service is started, the enabling peripheral service determines the time for setting the first peripheral driving mark true according to the pre-stored information. The pre-stored information comprises state information of the application program when the system is closed last time, wherein the state information comprises whether the application program is in an operating state when the system is closed last time, and whether the application program operates the external device when the application program is in the operating state. Specifically, if the pre-stored information is information that the application program is in a state of running the external device when the system is turned off last time, the peripheral service is enabled to modify the pre-stored second peripheral driver flag false into the first peripheral driver flag true when the peripheral service is started, and store the modified first peripheral driver flag true into the memory 23. For example, when the system is turned off last time, the running program is a multimedia playing program, and the program is in a state of running the external device, so that the peripheral service modifies the pre-stored second peripheral driver flag false to the first peripheral driver flag true when being started, and stores the modified first peripheral driver flag true in the memory 23.
In another specific implementation scenario, the car platform is an automobile platform, the external device is a usb flash disk with an LED lamp, the first external driver is marked as true, and the second external driver is marked as false. And if the enabling peripheral service reads the mark of the first peripheral drive mark true, the action of loading the external equipment is executed, and if the enabling peripheral service reads the mark of the second peripheral drive mark false, the action of loading the external equipment is not executed. The processor 22 judges that the external device exists through the peripheral driver, and reads the second driving flag pre-stored in the memory 23 through the peripheral driver. Since the second peripheral driver flag is false, processor 22 does not load the peripheral first. After the peripheral service is started, the peripheral service determines the time for setting the first peripheral drive flag true according to pre-stored information, wherein the pre-stored information includes state information of an application program when the system is closed last time, the state information includes whether the application program is in a running state when the system is closed last time, and when the application program is in the running state, whether the application program runs the external device. Specifically, if the pre-stored information is information that the application program is in a state of not running the external device when the system is closed last time, after the display of the desktop of the vehicle is completed, the peripheral service is enabled to modify the pre-stored second peripheral drive flag false into the first peripheral drive flag true, and store the modified first peripheral drive flag true in the memory 23. For example, when the system is turned off last time, the running program is a radio, and the program is in a state where the external device is not running, and then the system is normal and the desktop display is completed this time, the peripheral service is enabled to modify the pre-stored second peripheral driver flag false into the first peripheral driver flag true and store the first peripheral driver flag true in the memory 23.
In other implementation scenarios, if the pre-stored information is the external device loading time set by the user, the enabling peripheral service may directly modify the pre-stored second external driving flag false to the first external driving flag true at the set time according to the pre-stored information and store the modified first external driving flag true in the memory 23.
Further, if the processor 22 determines that no external device exists through the peripheral driver, the processor 22 directly starts the system and related programs on the system according to a default sequence.
After the enabling peripheral service modifies the second peripheral driving flag false pre-stored in the memory 22 into the first peripheral driving flag true, the processor 22 calls the peripheral driving to detect whether the external device exists through the enabling peripheral interface. And the processor 22 reads the peripheral driving mark again through the peripheral driving, and loads the USB flash disk with the LED lamp after determining that the peripheral driving mark is the first peripheral driving mark true, wherein the LED lamp flashes when the USB flash disk is loaded.
In the above embodiment, when the instruction to start the system is obtained, if the information pre-stored in the memory 23 is two kinds of information, namely, the state that the application program is running the external device when the system is turned off last time and the state that the application program is not running the external device when the system is turned off last time, when the processor 22 loads the usb disk carrying the LED lamp in the same system, the latter has a delay with respect to the loading time of the former, where the delay time is longer than 100ms, that is, the time taken by the two usb disks from obtaining the instruction to start the system to flashing the LED lamp of the usb disk for the first time is not consistent, and the latter is at least 100ms longer than the former.
Different from the situation of the prior art, the method and the system firstly judge whether the external equipment exists or not when the instruction for starting the system is obtained, enable the peripheral service to determine the time for setting the first peripheral driving mark for the external equipment according to the pre-stored information when the external equipment exists, and load the external equipment according to the first peripheral driving mark. According to the invention, when the vehicle machine is started, the external equipment is not directly detected and loaded, but the time for loading the external equipment is determined according to the pre-stored information, so that the starting time of the vehicle machine is effectively shortened, and the user experience is improved.
Furthermore, the invention also provides a vehicle which comprises any one of the vehicle-mounted machine systems. The vehicle of the invention can be a truck, a passenger car, a car, an electric vehicle and other vehicles, and is not limited in detail here.
