Row step 512.
Step 503: obtaining alcohol content information and driver's physical ability information.
Since gas with various is by different material molecular composition, it can in absorption spectrum corresponding wavelength light, and inhaling
Off peak wave band is received, uptake is very small, and the intensity before and after laser irradiation under test gas can be acquired using laser detecting apparatus
Variation, calculates under test gas alcohol concentration (general 1.3998 μm~1.3928 μ m of alcohol gas wavelength region), obtains
Alcohol content information；Specifically, laser detecting apparatus includes: laser emitter, laser pickoff, signal receiver, signal amplification
Device and control unit；Laser emitter gas into vehicle emits laser signal, using vehicle indoor gas to laser reflection, swashs
Optical receiver receives gas reflection signal and is simultaneously converted into electric signal, electric signal by signal receiver amplify with convert after,
It is sent to control unit, alcohol content information is calculated by control unit.
Step 504: determining whether driver is drunk driving by alcohol content information and driver's physical ability information；If it is not, holding
Row step 505；If so, executing step 512.
Since laser detecting apparatus is only able to detect automotive interior alcohol concentration, it can be detected drive by assisted detector here
Whether the person of sailing is the personnel that drink, and detects driver according to the sensors such as personnel body variation characteristic, including heart rate, electric current are drunk
Member whether be the state of drinking, with this come judge driver take in alcohol content, and remind driver forbid drive vehicle.
Specifically, driver's physical ability information includes: heart rate, oxygen content, skin temperature and epidermis humidity.The present embodiment
In, it can judge whether driver is drunk driving by interior alcohol content and heart rate.
Step 505: judging whether the physical efficiency of driver is good by driver's physical ability information；If so, executing step 506；If
It is no, execute step 512.
Step 506: vehicle being allowed normally to start.
Step 507: in vehicle travel process, obtaining position of driver information and driver's physical ability information.
Step 508: judging whether the physical efficiency of driver is good by driver's physical ability information；If so, executing step 509；If
It is no, execute step 513.
Step 509: whether the posture that driver is judged by position of driver information is standard vehicle driving posture；If so, executing
Step 511；If it is not, executing step 510.
Step 510: in the range that steering wheel is adjusted, section being finely adjusted to steering wheel, so that the posture of driver accords with
Standardization vehicle driving posture.
Step 511: terminating.
Step 512: not allowing vehicle normally to start.
Step 513: being alarmed or prompted.
Safe driving method provided in an embodiment of the present invention, after receiving vehicle launch signal, according to palm print information, really
Determine whether driver is car owner；When driver is car owner, judge whether driver is drunk driving, and judge driver whether physical efficiency
Well, if the not non-drunk driving of driver and driver's physical efficiency is good, allow vehicle launch.The technical solution of the present embodiment, can be with
Prevent drunk driving, reduce fatigue driving and driving bring security risk lack of standardization, can adjust in time and stop dangerous vehicle launch
Habit, to ensure that the safety of the operation of vehicle in advance before vehicle operation.
Embodiment six
As another technical solution of the invention, as shown in fig. 6, the safe driving system provided for the embodiment of the present invention six
The structural block diagram of system, in the present embodiment six, safety driving system includes: steering wheel, and steering wheel micro actuator is provided on steering wheel
11, position sensor 12 and physical efficiency sensor 13；Further include: processor 2, alarm or prompting device 3.
Position sensor 12 is for acquiring position of driver information.
Physical efficiency sensor 13 is for acquiring driver's physical ability information.
Steering wheel micro actuator 11 is used to adjust the displacement that steering wheel carries out set amount in different directions.Specifically, steering wheel
Micro actuator is steering wheel can be made in different directions, for example front and back carries out the mobile device of set amount up and down, and set amount
It is determined by steering wheel micro actuator mechanical structure.
Processor 2 obtains driver's physical ability information and position of driver information in vehicle travel process；By driver's body
Energy information judges whether the physical efficiency of driver is good；When the physical efficiency of driver is good, processor is sentenced by position of driver information
Whether the posture of disconnected driver is standard vehicle driving posture；When the posture of driver is not standard gestures, control steering wheel fine tuning
Device is finely adjusted section to steering wheel, so that the posture of driver complies with standard vehicle driving posture in the range that steering wheel is adjusted；
When the physical efficiency of driver is bad, control alarm is alarmed or is controlled prompting device and prompted.
In the present embodiment, installation direction disk micro actuator, position sensor and physical efficiency sensor, make direction on the steering wheel
Disk becomes safe steering wheel, and safe steering wheel, and first is to solve the problems, such as asking for driver itself driving and emergency case
Topic, for example, safety certification, that is, judge whether current driver has the preliminary judgement for driving permission and driving ability；Second
It is exactly driver's self reason, for example, fatigue driving, hypervelocity, driving lack of standardization, third is exactly that emergency case includes burst disease
Disease and special circumstances (unexpected lack of standardization, running speed exception of travel route etc.).
Safety driving system provided by the invention, according to driver's physical ability information and position of driver information, to direction
Disk is adjusted, and has ensured that vehicle can drive safely, and when driver's physical efficiency is bad, reminds driver in time, further,
The safety of Vehicle And Personnel is ensured.
Further, pressure sensor, position indicator and timing are additionally provided in another embodiment of the present invention, on steering wheel
Device.Wherein, pressure sensor is for acquiring steering wheel pressure；Position indicator is used to acquire the track of vehicle information of vehicle；Timer
For timing.
Processor by steering wheel pressure judge driver whether be both hands drive, one hand drive or without hand drive:
When driver is that both hands drive, processor determines that driver is safe driving.
When driver is one hand drive, processor judges whether vehicle deviates and offset is greater than by track of vehicle information
Set distance；If offset be greater than set distance, processor control alarm alarmed and control vehicle deceleration traveling until
Until vehicle stops.Specifically, set distance can be set according to different type vehicle, for example, set distance is 0.5m.
If offset is less than or equal to set distance, processor control alarm is alarmed.
When driver drives for no hand, processor control timer starts timing, and is less than and sets in timer
When fixing time, processor by track of vehicle information judge vehicle whether deviating track；If so, control alarm is alarmed and is controlled
Vehicle deceleration traveling processed is until vehicle stops.
Specifically, setting time can be set according to different type vehicle, for example, setting time is 10s.
When processor is more than setting time in timer, control alarm is alarmed and controls vehicle deceleration traveling
Until vehicle stops.
