In the above-described embodiments; Through portable terminal external equipment is driven; Make portable terminal to communicate with external equipment, portable terminal can be exported directly being sent to external equipment through the corresponding output signal that moves the application software generation then.In the present invention; Because application software, drive software all not in vehicle-mounted end operation, therefore, need not to install the described computer end as in the background technology at vehicle-mounted end; Only need a vehicle-mounted circuit card, the output signal that receives is sent to cooresponding external equipment gets final product.Compare prior art, the present invention has simplified the component design of vehicle-mounted end, has reduced the cost of producing vehicle-mounted end.

And, compare existing vehicle-mounted information and entertainment system, the time-to-market of portable terminal is short, and renewal speed is fast, can satisfy the demand that the user grows with each passing hour.

In addition, the vehicle-mounted end among the present invention, its equipment and function have universality, when the user has new demand again, only need new portable terminal of purchase or new application software to get final product, and need not vehicle-mounted end is done improvement.Therefore, prolonged the life cycle of vehicle-mounted end.

In an embodiment of the present invention, vehicle-mounted end can link to each other with portable terminal through an interface.Realize the transmission of signal through the input and output of defining interface signal.But in concrete application; Though the external equipment of most vehicle-mounted end is basic identical, existing portable terminal has polytype such as mobile phone; Every type of operating system of being supported maybe and different, the hardware system of corresponding exploitation maybe also can be different.Therefore, vehicle-mounted end can't link to each other with polytype portable terminal through an interface.For this reason, in embodiments of the invention 2, referring to Fig. 2, system also comprises connecting device 23, and the vehicle-mounted circuit card 211 of vehicle-mounted end 21 links to each other through connecting device 23 with portable terminal 22.Wherein, connecting device 23 links to each other through standard interface 231 with vehicle-mounted end 21, links to each other through first interface 232 with portable terminal.First interface 232 is interfaces that the type with portable terminal 22 is complementary.Such as the iOS equipment for Apple, first interface can be the connecting interface of similar apple 30 pins, and possibly be exactly a USB connecting interface for the Android mobile phone.

After external equipment is driven into merit; Vehicle-mounted circuit card 211 will at first be sent to first incoming signal that from external equipment 212, receives the standard interface 231 of connecting device 23, and connecting device 23 is sent to portable terminal through first interface 232 with first incoming signal more then.
