Description
Technical field: the present invention relates to a kind of driving hands of vehicle steering wheel to incude detection device from state.
Background technique: in order to which car steering process is safer, usually when driving, both hands should not leave steering wheel.Now
There is can detecte device of the steering wheel hand from state, sensor is set in steering wheel, is slipped out of the hand if there is steering wheel
Situation can incude rapidly detection and trigger signal to turn-key system.But the prior art is judging steering wheel whether hand is from shape
When state, generally only the circumferential part of sensing detection steering wheel whether and human contact, if left hand and right hand is not held in correct behaviour respectively
Make position, or only gently taken using hand, shelve the incorrect vehicle driving postures such as contact steering wheel, also judges and do not slip out of the hand,
Not enough, it is still necessary to improve for safe ilities for the accuracy of detection.
Summary of the invention: in view of the deficiencies of the prior art, the present invention, which provides one kind, to be incuded with subregion, the direction of accuracy of judgement
Disk hand is from induction detection device.
The present invention includes the sensor being arranged in steering wheel, and the sensor has several, and each sensor is by one
Group thin wire is constituted, and each sensor is all connected in flexible substrate layer, and flexible substrate layer is fixed the strip of paper used for sealing for being wrapped in steering wheel
Layer lower section, each sensor correspond respectively to the different hand griping positions in steering wheel circumference portion in the link position on flexible substrate layer
Place, forms steering wheel feel several different area.
Further, heating stratum reticulare is additionally provided in steering wheel, which is located at below flexible substrate layer and the two
Between be equipped with shielded layer be isolated.
Specifically, there are five sensors, correspond respectively to the lower half in steering wheel circumference portion, upper left half portion, left outside,
Outside surface position in upper right half portion and the right side, forms five steering wheel feel areas.
The present invention is respectively induced detection using multiple and different steering wheel feel areas, and the inductive signal of different zones summarizes,
Can make the more acurrate contact position for judging steering wheel and driver's both hands of turn-key system, hold posture etc., it avoids failing to report mistake
Report, high reliablity can obviously help to improve safe ilities.Also, each sensor of the invention is all connected to flexible base
In layer of cloth, it is convenient for distributing adjustment, is assembled in steering wheel and is also easier to conveniently, it is versatile.
The present invention is further illustrated with reference to the accompanying drawings and detailed description.

Specific embodiment 1: as shown in Figure 1 to Figure 3, sensor 2 is arranged in steering wheel 4, and the sensor 2 has several
A, each sensor 2 is made of one group of thin wire, and each sensor 2 is all connected in flexible substrate layer 3, and flexible substrate layer 3 is consolidated
Surely it is wrapped in 4 lower section of strip of paper used for sealing layer of steering wheel 1, link position of each sensor 2 on flexible substrate layer 3 corresponds respectively to direction
At different hand griping positions on 1 circumferential part of disk, steering wheel feel several different area 5 is formed.In the present embodiment, sensor
There are five 2, correspond respectively to external in lower half, upper left half portion, left outside, upper right half portion and the right side of 1 circumferential part of steering wheel
Surface location forms five steering wheel feel areas 5.
When a hand correctly sufficiently holds the circumferential part of steering wheel 1, there is multiple directions disk feel area 5 that can all produce at holding
Raw inductive signal.Such as left hand grip, the lower half of 1 circumferential part of steering wheel, upper left half portion, the trizonal correspondence in left outside
Sensor 2 can all incude.If both hands are all correctly sufficiently held, all five steering wheel feel areas 5 can all generate induction letter
Number.If hand only using gently taking, shelving the postures such as contact steering wheel 1, generates 5 quantity of steering wheel feel area of inductive signal
It also can be different with position.Such as all only the back of the hand rests on the both sides of steering wheel 1 to both hands, only in the upper left half portion of 1 circumferential part of steering wheel
Inductive signal is generated with two steering wheel feel areas 5 at upper right half portion.The inductive signal of each sensor 2 is sentenced by turn-key system synthesis
Not, the specific contact area and operating gesture of driver's both hands and steering wheel 1 can be accurately judged to.
Flexible substrate layer 3 generally uses nonwoven cotton, and thin wire can weave fixed in nonwoven cotton namely sensor
2 can be integrally attached in flexible substrate layer 3, and production assembly is more convenient.Also, suitable thin wire is selected, can not only be passed
The low current of defeated inductive signal can also be used as heater wire group simultaneously, provide steering wheel heating function.It is of course also possible to such as Fig. 4 institute
Show, heating stratum reticulare 6 is additionally provided in steering wheel 1, which is located at 3 lower section of flexible substrate layer and is equipped between the two
Shielded layer 7 is isolated.It senses in this way and heats separation, and prevent to interfere using shielded layer 7.
Specific embodiment 2: as shown in Figure 5 and Figure 6, there are three sensors 2, corresponds respectively to 1 circumferential part of steering wheel
Lower half, upper left half portion and upper right half portion surface location, form three steering wheel feel areas 5, remaining structure is substantially and specific real
It is identical to apply mode 1.
Also basic and specific embodiment 1 is identical for the process of induction detection operations, but at most only there are three steering wheel hands
Sensillary area 5 can incude, and the differentiation fine degree of specific contact area and operating gesture to both hands and steering wheel 1 slightly has letter
Change.
Specific embodiment 3: as shown in Figure 7 and Figure 8, sensor 2 has two, corresponds respectively to 1 circumferential part of steering wheel
Left and right half portion surface location forms two steering wheel feel areas 5, remaining structure is basic and specific embodiment 1 is identical.
Also basic and specific embodiment 1 is identical for the process of induction detection operations, but at most only two steering wheel hands
Sensillary area 5 can incude, and the differentiation fine degree of specific contact area and operating gesture to both hands and steering wheel 1 is simpler
Change, generally only judges whether left hand and right hand holds steering wheel 1.
