Description
Technical field
The utility model relates to a kind of auto-safety mechanism, particularly relates to a kind of vehicle speed control system based on seat belt sensor.
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.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of vehicle speed control system based on seat belt sensor that accurately can detect occupant and whether correctly fasten the safety belt, control automobile can be forced when occupant does not fasten the safety belt to travel with safety speed.
The technical scheme that the utility model 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 and accel control;
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 beneficial effects of the utility model are: 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 utility model 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.

Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Fig. 1 is the structural representation of a kind of vehicle speed control system based on seat belt sensor of the utility model.
Based on a vehicle speed control system for seat belt sensor, comprise safety strap 1, electronic control unit 8 and accel control 9;
Described safety strap 1 comprises buckle 2, draw-in groove 3 and belt body 4, and described buckle 2 is provided with buckle sensor 5, and described belt body 4 is provided with band body sensor 6;
Whether described buckle sensor 5 snaps in described draw-in groove 3 for detecting described buckle 2, and testing result is sent to electronic control unit 8; Whether described band body sensor 6 presses close to the person for detecting described belt body 4, and testing result is sent to electronic control unit 8; Described electronic control unit 8 controls described accel control 9 according to the testing result of the testing result of described buckle sensor 5 and described band body sensor 6.
