In some illustrative embodiment, also comprise: be arranged on power management module 3 between described primary processor 4 and described vehicle power 7, in described power management module 3, there is at least one electric pressure converter, each described electric pressure converter, its input end connects described vehicle power 7, and its output terminal is connected with described primary processor 4.
The structural representation of a kind of intelligent vehicle mounted terminal in the illustrative embodiment in the present invention is shown with reference to Fig. 2, Fig. 2.
Comprise: primary processor 4, the vehicle power 7 be connected with described primary processor 4 and each function element 8 be connected with described primary processor 4 by CAN 5, in described each function element 8, at least there is car door lock element 6, also comprise: wake module 1 and power-supply controller of electric 2; Described wake module 1, its input end accesses described CAN 5, and its output terminal is connected with described power-supply controller of electric 2, for when monitoring out described car door lock element 6 and opening, wakes described power-supply controller of electric 2 up; Described power-supply controller of electric 2, connects described primary processor 4 and vehicle power 7, during for being waken up, controlling vehicle power 7 and powering on for described primary processor 4.Ignition lock element 9 is also comprised in described each function element 8;
Described intelligent vehicle mounted terminal also comprises: detection module 10, its input end accesses described CAN 5, its output terminal is connected with described power-supply controller of electric 2, for when monitoring out described ignition lock element 9 and opening, trigger described power-supply controller of electric 2 and control described vehicle power 7 and power on for described each function element 8.
Wherein, described wake module 1 is the first CAN transceiver; Described detection module 10 selects the second CAN transceiver or current sensor
Pass through said structure, can be implemented in (when car owner is by car key opening car door) when car door lock is converted to opening from lock-out state, wake module wakes controller up, it is that primary processor powers on that controller controls vehicle power, primary processor is started separately, (this holding state supports status information during vehicle-mounted computer reading car locking last time to enter holding state, automobile is managed), when making automotive ignition, each function element powers on, and now primary processor can be managed as a whole each function element fast.When automobile flameout, each function element stops powering on, primary processor enters holding state again, and (now primary processor stores the status information of Current vehicle, be convenient to call when opening next time), when car door lock is converted to lock-out state from opening (car locking), power-supply controller of electric stops controlling vehicle power and powers on to primary processor, and primary processor is out of service.
Automobile causes automobile flameout due to some road conditions problems, car owner's experience problem and some other special circumstances, when again lighting a fire, only each function element in automobile is powered on, primary processor is still in running status, realize starting fast, and avoid instantaneous unlatching or the closedown of primary processor, the waste of energy that the ON/OFF reducing primary processor causes, realizes energy-saving effect.
All parts in above-described embodiment, the control flow of realization in the prior art, is by independent chip, and such as, the processor pointed out in background technology, can realize inserting the lockhole of automobile from key, most the flow process that powers on of each components and parts.There is problem described above in this scheme, such as, structure is single, is not easy to safeguard.By the scheme of the application, although add the annexation between parts and parts, the control algorithm amount of all parts reduces, and stable, single component costs is lower, improves stability and the reliability of system.
