Description
Technical field
The present invention relates to a kind of auto-safety mechanism, particularly relate to a kind of vehicle speed control system based on seat belt sensor and control method thereof.
Background technology
Safety strap is called " life zone " of automobile visually by people.Exactly because the importance of safety strap, nowadays, a lot of car has safety strap audible alarm unit, some vehicles have become standard configuration, the object of setting only has one, reminds driver to fasten one's safety belt in time exactly.If the occupant at front row does not fasten one's safety belt, warning device will grow from weak to strong, and sound does not stop.
But this is to the vital device of driver safety, now but by a kind of pocket-handkerchief to instead of, although its height is little, as long as its inserted in safety strap draw-in groove, safety band alarm device will " be shut up ".This pocket-handkerchief is called as safety belt buckle, in market and have sale on the net.
The warning that automobile is arranged is avoided in existing automotive safety prompting prompting meeting easily by this buckle, shield the prompting of automobile safety system to the occupant that do not fasten the safety belt.
Summary of the invention
Whether technical matters to be solved by this invention is to provide and a kind ofly accurately can detects occupant and correctly fasten the safety belt, can force to control the vehicle speed control system based on seat belt sensor that automobile travels with safety speed and control method thereof when occupant does not fasten the safety belt.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of vehicle speed control system based on seat belt sensor, comprises safety strap, electronic control unit, accel control and annunciator;
Described safety strap comprises buckle, draw-in groove and belt body, and described buckle is provided with buckle sensor, and described belt body is provided with band body sensor;
Whether described buckle sensor snaps in described draw-in groove for detecting described buckle, and testing result is sent to electronic control unit; Whether described band body sensor presses close to the person for detecting described belt body, and testing result is sent to electronic control unit; Described electronic control unit controls described accel control and annunciator according to the testing result of the testing result of described buckle sensor and described band body sensor;
The invention has the beneficial effects as follows: by detecting the position of the relative draw-in groove of described buckle sensor, can confirm whether described buckle is correctly assigned in described draw-in groove, meanwhile, detect described band body sensor to detect described belt body and whether press close to human body, can guarantee that occupant indeed fastens one's safety belt further, this two cover detecting device complement one another, increase native system to occupant whether use of seat belts detect reliability.
On the basis of technique scheme, the present invention can also do following improvement.
Further, in described draw-in groove, be provided with the coalignment with described buckle sensor unique match, described buckle sensor for detect described buckle sensor whether with described coalignment location matches.
The beneficial effect of above-mentioned further scheme is adopted to be, in existing belt system, when occupant replaces safety belt buckle with other objects, and when being inserted in draw-in groove, safety strap monitoring system can be allowed to take for the proper use of safety strap of occupant.Native system is arranged at the coalignment of described buckle sensor unique match in described draw-in groove, occupant just can be avoided to use other object belt body safety belt buckles, thus avoid the dangerous situation of occupant's safety belt buckling free.Whether buckle sensor can mate with described coalignment by direct-detection buckle sensor, simplifies the collection of native system to snapped-in position information.
Further, described coalignment is built-in with the magnetic for generation of irregular magnetic field, and described buckle sensor is magnetic field sensor.
The beneficial effect of above-mentioned further scheme is adopted to be, irregular magnetic field is produced by the magnetic being built in described coalignment, be equivalent to construct a magnetic key by this magnetic field, and buckle sensor is by gathering the magnetic-field intensity around it, judge whether and coalignment location matches, in this programme, play the role of magnetic lock.And only have and just to think the location matches of itself and coalignment when buckle sensor detects specific magnetic field (i.e. described coalignment produce magnetic field).This system of using magnetic lock and magnetic key fit system, can prevent occupant from using other objects to replace buckle, improve the safety factor of native system.
Further, described band body sensor is infrared pickoff, and described buckle sensor is all connected with described electronic control unit by wireless telecommunications with band body sensor.
The beneficial effect of above-mentioned further scheme is adopted to be utilize infrared pickoff can detect the distance of its relative human body easily.Infrared pickoff manufacturing technology is ripe, easy to use.
The present invention also provides a kind of method for controlling driving speed based on seat belt sensor, comprises the following steps:
S100, collection reflect the snapped-in position information of buckle and draw-in groove relative position and reflect the belt body location information of belt body and human body relative position;
S200, described snapped-in position information and belt body location information are sent to vehicle electronic control unit;
S300, vehicle electronic control unit control throttle and annunciator according to described snapped-in position information and described belt body location information.
The collection of described snapped-in position information is completed jointly by the buckle sensor be arranged on buckle and the coalignment be arranged in draw-in groove, and namely when buckle and draw-in groove exact connect ion, snapped-in position information is correct position, otherwise is positional fault.
Described coalignment produces magnetic field, and described buckle sensor gathers the Magnetic Field in described magnetic field, and determines described buckle and draw-in groove whether exact connect ion by described Magnetic Field, thus determines that described snapped-in position information is correct position or positional fault.
Described belt body location information is gathered by the infrared pickoff be arranged on belt body, described belt body location information refers to the distance of infrared pickoff and human body, when the distance of infrared pickoff and human body is less than preset value, described belt body location information is correct position, otherwise is positional fault.
Described snapped-in position information and belt body location information are all sent to vehicle electronic control unit by the mode of wireless telecommunications.
When electronic control unit detects that described snapped-in position information be positional fault or described belt body location information is positional fault, control throttle with the minimum delivery volume preset to engine oil, and control alarm equipment alarm.
The invention has the beneficial effects as follows: by detecting the snapped-in position information of reflection buckle and draw-in groove relative position and reflecting the belt body location information of belt body and human body relative position, directly judge whether occupant correctly fastens the safety belt, directly control throttle by electronic control unit, to ensure the driving safety of occupant when not fastening the safety belt simultaneously.
