Embodiment

Relevant the present invention is for reaching above-mentioned purpose, and the technological means adopting and effect thereof, hereby lift preferred embodiment, and coordinate graphic be illustrated as follows.

Please refer to Fig. 2, is the schematic diagram of device for vehicular electronic 10 of the present invention.Device for vehicular electronic 10 of the present invention is supplied with electric power by power supply on vehicle 11, device for vehicular electronic 10 comprises processing unit 12, media units 13, display unit 14, loudspeaker unit 15, dynamic memory unit 16, storage element 17, timing unit 18 and detecting unit 19 etc., device for vehicular electronic 10 detects the on off state of power switch 20 by detecting unit 19, when detecting power switch 20 when opening state (ON), processing unit 12 is controlled by power supply on vehicle 11 and is received electric power, supply with each unit electric power in device for vehicular electronic 10, start device for vehicular electronic 10.Utilize and select and adjust media units 13, such as radio, Digital Television and DVD, dial modes of operation such as putting device, receive or produce video-audio signal, through processing unit 12, enable the application program of operating system in non-volatile storage element 17, coordinate after dynamic memory unit 16 buffered of volatibility, picture signal is presented on to display unit 14 and exports voice signal to loudspeaker unit 15.The application program that device for vehicular electronic 10 operating systems are enabled and mode of operation change the use with operating system, and are temporarily stored in dynamic memory unit 16.

When device for vehicular electronic 10 powered-down switch 20, detecting unit 19 1 detects power switch 20 for off status (OFF), processing unit 12 switches to sleep pattern by device for vehicular electronic 10, the data that only maintain processing unit 12 and preserve dynamic memory unit 16 with lower electric power, and close the electric power of media units 13, display unit 14, loudspeaker unit 15 and storage element 17, and close the major clock of processing unit 12, in order to avoid consume the electric power of power supply on vehicle 20 excessively.Device for vehicular electronic 10 is during powered-down switch 20, by timing unit 18 timing at special time, special time can be the scheduled period, such as 12 hours or regular intervals of time time etc., or predetermined opportunity, such as unmanned opportune moments of driving at 2 of midnight etc., device for vehicular electronic 10 resets automatically.

While automatically starting, with user, do not see device for vehicular electronic 10 outward appearance evolutionary modes, for example, close display unit 14 and loudspeaker unit 15 is not exported audio-visual state, from sleep pattern, start device for vehicular electronic 10.Processing unit 12 is kept in the data of dynamic memory unit 16 during by powered-down switch 20, before closing, enable the kind of application program, for example radio program, frequency of radio station or multimedia playing program, played file title, time point, and the mode of operation of operating system, form recovery file and be stored to storage element 17.Close all application programs, remove the data of dynamic memory unit 16.And then the kind of application program and the mode of operation of operating system of the recovery file of execution storage, make only temporary relevant application program and the mode of operation of recovery file of dynamic memory unit 16.Then close device for vehicular electronic 10, again switch to sleep pattern.Wait for when next user starts device for vehicular electronic 10, allow and preserve the dynamic memory unit 16 of simplifying, the normal device for vehicular electronic 10 that starts fast, get back to user's origin operation state, avoid the irrelevant program in dynamic memory unit or data, long-time while preserving leakage, cannot normally start and affect the quick startup of device for vehicular electronic 10.

As shown in Figure 3, be the process flow diagram of first embodiment of the invention device for vehicular electronic quick start method.The step-by-step procedures of device for vehicular electronic quick start method of the present invention is as follows: at step S1, detect switching-on and switching-off state; When step S2 power switch is closed condition, device for vehicular electronic switches to sleep pattern; Step S3 restarts device for vehicular electronic in special time; Enter step S4, store device for vehicular electronic and be kept at the recovery file in dynamic memory unit; At step S5, remove the data of dynamic memory unit; Enter step S6, carry out the recovery file storing; Step S7, device for vehicular electronic enters sleep pattern.

Therefore, first embodiment of the invention device for vehicular electronic quick start method, can utilize while detecting power switch for closed condition, device for vehicular electronic is switched to sleep pattern, in special time, restart device for vehicular electronic again, store after the recovery file of device for vehicular electronic, remove the data of dynamic memory unit, again carry out the device for vehicular electronic recovery file storing, simplify the data that dynamic memory unit is preserved, enter again sleep pattern, while allowing user start device for vehicular electronic next time, preserve the dynamic memory unit of simplifying, reach the object that fast and stable starts.

As shown in Figure 4, be the process flow diagram of second embodiment of the invention device for vehicular electronic quick start method.Although within first o'clock of the present invention, execute example, utilize to remove dynamic memory unit, simplify the data of enabling the kind of application program and the mode of operation of operating system before closing that dynamic memory unit preserves, with the startup device for vehicular electronic of fast and stable.But because device for vehicular electronic operating system of the present invention is often damaged because of undesired access part, need reparation consuming time.For avoiding affecting the stability that device for vehicular electronic starts fast, second embodiment of the invention utilizes first embodiment of the invention to remove before dynamic memory unit, reclaim the data of dynamic memory unit, repair the operating system of device for vehicular electronic, to accelerate to repair and promote the stability that device for vehicular electronic starts fast simultaneously.

The step-by-step procedures of device for vehicular electronic quick start method of the present invention is as follows: at step T1, detect switching-on and switching-off state; Step T2 is when power switch is closed condition, and device for vehicular electronic switches to sleep pattern; Step T3 restarts device for vehicular electronic in special time; Enter step T4, store device for vehicular electronic and be kept at the recovery file in dynamic memory unit; At step T5, repair the operating system of device for vehicular electronic; At step T6, remove the data of dynamic memory unit; Enter step T7, carry out the recovery file storing; Step T8, device for vehicular electronic enters sleep pattern.

Therefore, second embodiment of the invention device for vehicular electronic quick start method, can after closing, automatically start by device for vehicular electronic, while simplifying the save data of dynamic memory unit, before removing dynamic memory unit, reclaim the data of dynamic memory unit, carry out the operating system of repairing device for vehicular electronic, the activity duration of avoiding repairing operating system affects the quick startup of device for vehicular electronic, reaches the object of the degree of stability of guaranteeing that device for vehicular electronic restarts fast.

As described above, only, in order to convenient explanation preferred embodiment of the present invention, scope of the present invention is not limited to these preferred embodiments, and all any changes of doing according to the present invention, in not departing under spirit of the present invention, all belong to the scope of the claims in the present invention.
