The evaluation methodology of parking stall resonable degree and principle：
Driver can produce different degrees of parking difficulty in docking process because of parking stall size and channel width, right
Different physiology, psychological characteristic can be shown in different parking difficulty drivers, and causes different driving behaviors, the row
The acceleration and deceleration of vehicle, corner, speed, pause etc. in show docking process.These physiological psychological qualities and parking behavior collection
In embody driver carrying out this time stop when the load of machinery systems.What parking load can be surveyed from following module：Electrocardio
Detection module 1, checking with EMG method module 2, GPS module 3, eye moves detection module 4.ECG detecting module 1 obtains driver and stopped
Changes in heart rate situation in journey, i.e., relative to calmness in the case of, driver's increased heart rate caused by highly difficult parking behavior
Degree.Checking with EMG method module 2 obtains the muscle strengh situation of change in driver's docking process, and the muscle strengh of high level continues
Time length then illustrates that parking difficulty is big.GPS module 3 obtains the positional information of vehicle, wherein with the adjustment number of times that pauses as accordingly finger
Mark, adjustment number of times is more, illustrates that parking difficulty is big.When watching attentively of eyes when the dynamic detection module 4 of eye can detect that driver is stopped
Between and pupil size, wherein using fixation time as the dynamic index of eye, the longer explanation driver of fixation time needs higher concentration
Attention, stops more difficult.
Load is specifically obtained and computational methods are as follows：
ECG detecting module 1, measures tranquil heart rate HR before driver is stopped1, driven by ECG detecting module 1
The real-time heart rate HR in people's docking process is sailed, HR-t images, image and y=HR is drawn1The areal calculation formula for being surrounded is：
This parking average heart rate computing formula：
Change rate of heartbeat computing formula：
Checking with EMG method module 2, muscle strengh is 0 under driver's relaxation state, when muscle strengh is more than X, then it is assumed that driven
People's muscle is in tension.Remember that lasting cumulative time of driver's muscle strengh more than X is t in whole docking process1, stop
During muscular tone percentage of time computing formula：
3 points of GPS module is rover station and base station, and in automobile, GPS module base station is located at automobile 50m to GPS module rover station
Within region, GPS module rover station and base station pass through bluetooth connection；GPS module 3, for detecting driver in docking process
The information such as middle vehicle location, speed, acceleration, corner, pause number of times, when parking difficulty is big, the number of times that vehicle is adjusted back and forth
Increase, remember that this time stops adjustment number of times for n.
The dynamic detection module 4 of eye, for detecting pupil size, fixation time length of the driver in docking process, wherein
Attention concentration degree in fixation time major embodiment driver's docking process, attention time of concentration is longer, represents that parking is got over
It is difficult.Note fixation time percentage ratio computing formula：
ECG detecting module 1, checking with EMG method module 2, GPS module 3, the dynamic detection module 4 of eye by the driver for detecting and
The real-time parking data of vehicle is stored into memory module 5, and message processing module 6 is used to process ECG detecting module, checking with EMG method
The dynamic detection module storage of module, GPS module, eye data in a storage module, message processing module 6 is calculated it, point
Change rate of heartbeat α, muscular tone percentage of time β are not obtained, frequency n, fixation time percentage ratio γ is adjusted.Message processing module
6 are calculated the parking stall parking carry calculation formula：
A, b, c, d, e are coefficient, and other symbolic significances are the same.
If considering the impact of parking stall and walkway occupied area, parking stall and parking stall dead ahead walkway region area
S=(a+c) * b, parking stall parking resistance
Adjustment parking stall size and walkway width are repeatedly tested, the group of each parking stall size and walkway width
Conjunction can obtain corresponding parking loadWith parking resistance λ.Resistance λ is less for parking, illustrates that driver's parking load is little, and should
Parking stall area is relatively small.
The ECG detecting module is used to detect the real-time heart rate situation of driver, represents when heart rate is fast and drive human psychological
Anxiety is big to the workload of driver from side reflection parking stall；Conversely, when driver's heart rate is steady, illustrating to stop relative
Easily, parking stall humanization designing.
The checking with EMG method module is used to detect the real-time muscle strengh of driver, in a docking process, if driver
Muscle strengh long-time is higher, illustrates that driver is firmly larger, stops difficult；If conversely, driver's muscle strengh is low and relative
Gently, illustrate to stop light, parking stall humanization designing.
GPS module is used to detect driver vehicle location, speed, acceleration, corner, pause number of times etc. in docking process
Information, if automobile pause number of times in docking process is excessive, illustrate to stop more difficult, the multiple translation-angle of needs just can stop into
Go；Conversely, corner significantly convert, pause number of times it is less, then stop be easier to, parking stall humanization designing.
The dynamic detection module of eye is used to detect pupil size, fixation time length of the driver in docking process, pupil phase
For it is initial when to become big, fixation time long, then illustrate driver attention high-pressure, easily cause fatigue；Conversely, then saying
It is bright to stop easy, parking stall humanization designing.
Memory module is used to store the dynamic detection module detection of ECG detecting module, checking with EMG method module, GPS module, eye
Drive personal data.
Message processing module is deposited for processing the dynamic detection module of ECG detecting module, checking with EMG method module, GPS module, eye
Storage data in a storage module, and with reference to parking stall occupied area size, message processing module process obtains stopping every time and drives
Sail the parking load of peopleWith the parking resistance λ on parking stall, so as to judge the resonable degree on parking stall.
The specific workflow of the system is as follows：
A1. the data acquisition end of the dynamic detection module of ECG detecting module, checking with EMG method module and eye is attached to into participation experiment
The corresponding site of driver, connects rover station and the base station of GPS module；

A5. without departing from parking stall scope, edge line is not pressed onto, vehicle is parked in central being considered as in parking stall and completes to stop
Car.
A6. by car open back test before original position, adjustment parking bit length, passage sideline distance (i.e. channel width) and
Parking stall form, repeats to stop.
In the described embodiment, the parking bit width a of each size, parking bit width b, walkway width c can be various
In the case of adjust, wherein parking bit width a, parking bit width b are not less than vehicle width, and width c in walkway is long not less than vehicle
Degree, concrete size can be designed according to actual requirement of engineering.
A kind of parking stall design system based on driver's physiological property is described in detail above, using above-mentioned system
System is obtained heart rate, muscle strengh, pause adjustment number of times, fixation time situation, parking plane of the driver in docking process
Product, by processing these information, obtains the parking resistance on the parking load size and parking stall caused to driver on the parking stall,
So as to judge parking stall design rationality.Above example is one kind of the practical application of the present invention, is used to help understand this
The principle of invention, is not construed as the restriction used the present invention.
