Accompanying drawing explanation
Fig. 1 is the circuit configurations schematic diagram of the embodiment of car trunk of the present invention induction self-starting system.
The realization of the object of the invention, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to Fig. 1, an embodiment of car trunk of the present invention induction self-starting system is proposed:
This car trunk induction self-starting system mainly applies PKE(English full name PASSIVE KEYLESS ENTER)-automotive keyless entering system and human body induction control technology, include the PKE main control module 10 be arranged in automobile, the PKE key 20 mated with PKE main control module 10, human body induction module 30 and the boot opening device 40 for driving car tail case lid to open.
This PKE main control module 10 comprises for receiving UHF(Ultra High Frequency, superfrequency radio wave) signal UHF receiver module 12, for sending LF(Low Frequency, low frequency radio wave) signal LF transmitter module 13 and for the treatment of and identify the MCU microcontroller A 11 of UHF signal received, UHF receiver module 12 comprises UHF reception antenna 121, LF transmitter module 13 and comprises LF transmitting antenna 131.Wherein, MCU microcontroller A 11 is PIC18F2680 chip.
