Description
Technical field
The utility model relates to the control of the output signal of kicking sensor, especially a kind of unified LIN and level signal are defeated
Kicking sensor system out.
Background technique
As electric back door is in the universal of passenger car market, the usage amount of kicking sensor is gradually increased, commercially available mainstream foot
Sensor is kicked, it is main to kick trigger signal using lin Bus data or directly using transmitting foot in the form of low and high level.
Foot kicks composition scheme as shown in Figure 1, input signal includes: capacitor antenna inductive signal A, capacitor day in the prior art
Line inductive signal B, power supply VCC, power supply GND；Output signal includes: LIN output, level signal output；What corresponding general foot was kicked
Connector is as follows: connector A(such as Fig. 2), the way of output (LIN output or level export) is fitted according to different automobile types, is needed simultaneously
Cover idle end (level output or LIN output)；Connector B(such as Fig. 3), double capacitor antenna form feet are kicked and can be completely unified.
By the prior art, individual two-way output signal is needed, but is directed to the real vehicle of different model, it can only be using wherein
A kind of form carries out trigger signal output, therefore actually uses, and has all the way that output signal needs the free time, causes connector type
It is inconsistent, it needs individually to process.Simultaneously as foot, which is kicked, belongs to waterproof components, it is also necessary to which idle port adds waterproof plug again, increases
Add process flow cost.
Summary of the invention
The utility model will solve the disadvantage that the above-mentioned prior art, and two different foot kick signals can be unified by providing one kind
Output interface reduces the kicking sensor system of design and subsequent machining cost.
The utility model solves the technical solution of its technical problem use: the foot of this unified LIN and level signal output
Sensing system, including Master control chip are kicked, the input signal connecting with Master control chip includes capacitor antenna A, capacitor antenna
B, power supply VCC, power supply GND, Master control chip connect level output by the port C1, and Master control chip is connected by the port C2
LIN chip, LIN chip connect LIN output, and level output and LIN output are merged into a LIN/ level output end mouth.
Preferably, the port C1 is connect with the output end of LIN chip.
Preferably, Master control chip is connect by the port C3 with a logic switch, the output end of LIN chip and the end C1
Mouth is connect with logic switch respectively, and logic switch connects LIN/ level output end mouth.The logic switch can be controllable hilted broadsword
Commutator.
Utility model has the advantages that: two different foot kick signal output interfaces can be unified, reduce design and
Subsequent machining cost.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Embodiment 1: such as Fig. 4, a kind of kicking sensor system of unified LIN and level signal output, including master control coremaking
Piece, the input signal connecting with Master control chip include capacitor antenna A, capacitor antenna B, power supply VCC, power supply GND, master control coremaking
Piece connects level output by the port C1, and Master control chip connects LIN chip by the port C2, and LIN chip connects LIN output,
The port C1 is connect with the output end of LIN chip, and level output and LIN output are merged into a LIN/ level output end mouth.Its is right
Answer connector as shown in Figure 5.
Scheme explanation: when using LIN signal as output signal, Master control chip (MCU) controls LIN chip by C2
LIN signal is exported, wherein the port C1 does not export；When using level signal as output signal, MCU is exported by C1 control terminal
Level signal, C2 port controlling LIN chip do not export.But the disadvantage is that since the port C1 is connected to control chip, the meeting when not exporting
In the presence of default level value (perseverance is high level or low level), LIN signal can be caused greatly to interfere, cause LIN signal can not
Normal transmission.
Embodiment 2: such as Fig. 6, a kind of kicking sensor system of unified LIN and level signal output, including master control coremaking
Piece, the input signal connecting with Master control chip include capacitor antenna A, capacitor antenna B, power supply VCC, power supply GND, master control coremaking
Piece connects level output by the port C1, and Master control chip connects LIN chip by the port C2, and LIN chip connects LIN output,
Master control chip is connect by the port C3 with a controllable single-pole double-throw switch (SPDT), the output end of LIN chip and the port C1 respectively with
Controllable single-pole double-throw switch (SPDT) connection, controllable single-pole double-throw switch (SPDT) connect LIN/ level output end mouth.Corresponding connector A and embodiment
1 is identical.
Scheme explanation: by controlling one logic switch on-off foot kick signal of chip controls, LIN signal and level signal energy
Enough keep apart, avoids influencing each other for scheme one.In terms of cost, increase a switching device, but connector and late design
Cost can reduce, and remain basically stable.To sum up, embodiment 2 has unified connector A, while in terms of cost almost without increase.Drop
Cost in terms of low late design.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
