Between communicated by CAN bus.
The Dinuclear Systems that control core ECU is constituted using fpga chip 4(Cyclone IV) with Cortex-A8 control panel 5,
It is consumed using the internal resource that FPGA shares ARM chip, accelerates data processing speed, secondary treatment is carried out to data, is improved
The accuracy of data.The main effect of fpga chip 4 exactly opens fingerprint, the engine 122 that fingerprint Identification sensor 2 acquires certainly
The data such as dynamic control and the induction of 11 touch pressure of steering wheel are pre-processed, then pass through DMA(direct memory access) it is passed to ARM
Chip is reprocessed, and passes corresponding data back fpga chip 4 again after having handled, and fpga chip 4 executes machine to corresponding again
Structure is operated, while ARM chip is also responsible for the data and life with car-mounted terminal 14,11 retaining mechanism of steering wheel and alarm 6
Order processing.Cortex-A8 control panel 5 is using Samsung S5PV210 as primary processor.
The model FPC1011F of fingerprint Identification sensor 2, fingerprint Identification sensor 2 may be provided at by steering wheel 11, side
Just user carries out fingerprint authentication after entering vehicle, and pressure sensor 3 carries out capacitive induction to the surface of steering wheel 11, passes through
Hand puts steering wheel 11 and generates the change of voltage and judge whether in safe driving, and realization is monitored safe driving, such as
Fruit is not at this time in safe driving, it will and the signal specific for generating a byte transfers information to fpga chip 4 by CAN bus,
Fpga chip 4 detects again makes corresponding instruction.Alarm 6 uses alarm lamp and emergency alarm bell, unsuccessful five times in fingerprint matching
Or hand-held continuous three seconds of driver are not placed on steering wheel 11 and carry out alarm and reminding.
As shown in figure 3,11 retaining mechanism of steering wheel includes the first clamping jaw 81, the second clamping jaw 82, screw rod 83 and locking motor
84, the first clamping jaw 81 and the second clamping jaw 82 are symmetricly set on the shaft two sides of steering wheel 11, and the first clamping jaw 81 passes through the first nut
85 connect with screw rod 83, and the second clamping jaw 82 is connected by the second nut 86 in screw rod 83, the first clamping jaw 81 and the second clamping jaw 82
Section is in semi-circular, and the screw thread of the screw thread of the first nut 85 and the second nut 86 is on the contrary, the driving end of locking motor 84 connects
One end of screw rod 83, Cortex-A8 control panel 5 connect locking motor 84, and when locking steering wheel 11, locking motor 84 drives screw rod
83 rotations drive the first clamping jaw 81 and the second clamping jaw 82 to move toward one another through the first nut 85 and the second nut 86, until the first folder
Pawl 81 and the second clamping jaw 82 hold the shaft of steering wheel 11 tightly, realize the locking of steering wheel 11, screw rod 83 and locking motor 84 pass through
Bracket is erected at the side of the shaft of steering wheel 11, realizes and fixes.11 locking mechanism of steering wheel will be unsuccessful in fingerprint matching
After five times, steering wheel 11 is locked, until fingerprint matching success, steering wheel 11 could be unlocked.
Chair regulator 13 includes driving the seat sliding block of seat slide and seat slide 132(or caterpillar belt structure), and
The seat of sliding block is driven to adjust motor 131 etc., the output end connecting chair of fpga chip 4 adjusts the control terminal of motor 131, seat
Adjust the stepper motor (110BLF230-630) that motor 131 is 3kw.Fpga chip 4 judges user according to fingerprint, and controls seat
Chair adjusts the position that motor 131 adjusts seat 133, and seat position is configured by the user, also using chair regulator 13
Increase the function of adjusting 133 backrest slope of seat.
The unlatching of starting-motor of engine 12 will be controlled by independent circuit, what which opened
Judgment basis is fingerprint successful match, and the unlatching of starting-motor of engine 12 will not be over 10 seconds, will first be suspended more than ten seconds
Three seconds, then started.
As shown in figure 4, the course of work of the multifunctional vehicle-borne control system based on fingerprint recognition is as follows:
User enters vehicle cab, puts his hand into fingerprint Identification sensor 2 and carries out fingerprint matching, fingerprint recognition sensing
Device 2 acquires the current finger print of user, and fpga chip 4 carries out pre-stored fingerprint in the fingerprint of user and storage card 7
Fingerprint matching, if fingerprint matching success, fpga chip 4 controls starting-motor of engine 12 and starts vehicle motor 122(engine
Start motor 12 and control the work of engine flywheel 121, to start engine 122), and according to the correspondence stored in storage card 7
Seat position controls chair regulator 13, and chair regulator 13 is adjusted seat；
If the unsuccessful number of fingerprint matching is more than setting number (such as 5 times), fpga chip 4 and Cortex-A8 are controlled
The mutual data of plate 5, Cortex-A8 control panel 5 controls 11 retaining mechanism of steering wheel and locks steering wheel 11, while controlling alarm
6 will alarm, the releasing of alarm still needs the success of fingerprint recognition, until fingerprint recognition success；
Vehicle motor 122 starts successfully, into safe driving detecting state, sets driver's hand not in fpga chip 4
The time interval (such as 3 seconds) of steering wheel 11 can be left, if being more than that time interval pressure sensor 3 does not collect pressure signal
(after i.e. 3 seconds, hand is still not returned to steering wheel 11), fpga chip 4 and the mutual data of Cortex-A8 control panel 5,
Cortex-A8 control panel 5 controls vehicle by car-mounted terminal 14 and reduces speed now, while controlling the alarm of alarm 6.
When Cortex-A8 control panel 5 is zero by the control vehicle deceleration of car-mounted terminal 14 to car speed, car-mounted terminal
14 remind whether start flame-out program, select as needed for driver；
Car-mounted terminal 14 is also used to typing fingerprint, whether fingerprint matching is successfully reminded.Fingerprint is added and deleted, it will
Meeting after fingerprint recognition success, shows that driver can according to need the addition for carrying out fingerprint in car-mounted terminal 14 again.
In 122 start-up course of engine, inevitably will appear the short time does not start, but cannot be driven using motor always
Flywheel turns, so Cortex-A8 control panel 5 passes through vehicle during starting-motor of engine 12 starts vehicle motor 122
Mounted terminal 14 obtain car status information and judge transmitter whether start completion, if be more than setting time in starting failure,
The work of starting-motor of engine 12 is controlled after separated in time again, while whether the prompting of car-mounted terminal 14 continues to start, and is used for
Driver chooses whether transmitter off starting motor as needed can choose if driver discovers the starting time too long
Starting is terminated, program will will appear termination.
The utility model is easy to operate, reliable for operation, can be convenient people's trip, without carrying car key, without manual
Adjust seat position, it is only necessary to which presetting parameter can automatically adjust and start under the fingerprint.
The utility model combines locked four functions of engine self-starting, safe driving, seat memory and steering wheel, section
The redesign of all parts is saved, fingerprint identification technology is adequately and reasonably utilized, realizes that function using maximizing, reduces cost.
Tthe utility model system is implanted into car-mounted terminal, becomes the subsystem of car-mounted terminal, facilitates the change of system, simultaneously
Save the cost for redesigning display module.
