Background technique
With the rapid development of social economy, road mileage open to traffic in China's increases year by year, and vehicle guaranteeding organic quantity is continuously increased,
Road Transportation is increasingly busy, and consequent is increasingly taking place frequently for traffic accident.Statistical result show driver not and
When obtain traffic information be the main reason for leading to traffic accident.
Currently, driver mainly passes through voice, image mode realizes people-car interaction, running information is obtained in time.It obtains
Running information includes that safety belt is not prompting, lane holding, tire pressure, fatigue driving prompt etc..
There are shortcomings and deficiency in actual operation in voice reminder mode.On the one hand, prompt tone is highly susceptible to outer
Boundary's noise jamming, for example, vehicle in severe road conditions, run at high speed or the driving process that opens a window in, it is easy to made an uproar by road noise, wind,
Power assembly noise and other influence of noises, the case where not received there are driver or receive incomplete prompting message.It is another
Aspect, part prompt tone (such as navigation hint sound) can interrupt or interfere car entertainment facility to operate normally.In addition to this, image mentions
Awake mode is easy to interference pilot's line of vision, and there are security risks.
For this reason, it may be necessary to a kind of alerting pattern of strong antijamming capability.

Embodiment two
Difference with embodiment one is that the driving of vibrating controller 02 vibration execution unit 03 is to correspond to vibration mode work
When, since vibrating 03 lowest vibration intensity of execution unit, it is gradually increased oscillation intensity, and after reaching corresponding oscillation intensity
2-10s is maintained, vibration is then stopped；5s is maintained in the present embodiment.
For example, it is desired to vibrate execution unit 03 when carrying out low intensive vibration since lowest vibration intensity, be gradually increased
Oscillation intensity, and after reaching low intensive oscillation intensity, the vibration of 5s is maintained, is then stopped.Since driver is driving vapour
Energy is concentrated when vehicle, if vibrated at the very start with low-intensity, precipitate vibration may cause to frighten to driver, shadow
Ring traffic safety, vibrated since lowest vibration intensity, driver can be allowed gradually to experience vibrating alert, prevent driver by
It is frightened, to guarantee traffic safety.
Embodiment three
Difference with embodiment one is, the location information of instrument board trouble light is also prestored in memory module.At information
After module is managed based on the dangerous item of situation of remote differentiation, the instrument board trouble light for showing the situation of remote is further determined whether, if
Have, the location information of instrument board trouble light is obtained from memory module；In the present embodiment, the location information of instrument board trouble light includes
Left side, centre and right side.The location information of instrument board trouble light is sent to vibrating controller 02 by message processing module；Vibration control
When device 02 processed matches the mode of vibration in vibration mode, the location information based on instrument board trouble light matches corresponding vibration side
Formula；In the present embodiment, the instrument board trouble light in left side corresponds to vibration on the left of cushion, and it is double that intermediate instrument board trouble light corresponds to cushion
Side vibration, the instrument board trouble light on right side correspond to vibration on the right side of cushion.
When certain failures occurs in automobile, the trouble light on corresponding instrument board can be lighted, but driver drives in wholwe-hearted
It sails, these information are easy to be ignored；Some vehicle failure lamps can be with prompt tone after lighting；Driver needs to take time after hearing
It goes for where failure occur, is not found if looked for one time, easily cause the impatient of driver.Pass through this programme driver
It can know on instrument board there is corresponding trouble light to light by the position of vibration, then trouble light on Quick positioning instrument dial plate
Position is handled in time so as to quick obtaining information.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and patent practicability.The scope of protection required by this application should be based on the content of the claims, in specification
The records such as specific embodiment can be used for explaining the content of claim.
