Description
Technical field
The present invention relates to automotive safety technology, specifically relate to a kind of automobile active safety prompt system, when in vehicle travel process, if chaufeur can not grip bearing circle effectively, system will provide alarm, thus improve drive safety, belong to automobile technical field.
Background technology
Along with the fast development of auto-industry and the mankind to automobile use frequent, increasing vehicle is set out on a journey traveling, and thing followed safety misadventure also constantly increases.In these accidents, most accident mainly causes because drive reason, wherein has considerable part accident to be owing to not controlling well in time caused by bearing circle during driver's steering vehicle.Some driver habit one hand controls bearing circle, another hand rides on car door, or smoking, even spare electronic machines such as using mobile phone, what accident was all given in these driving behaviors has buried hidden danger, because one hand obviously controls not as good as both hands the control in direction, if in emergency circumstances need significantly rotation direction at some, one hand cannot complete at all.Although there is various high-tech to be configured for active safety prompting at present, as blind area monitoring, deviation prompt system etc., but the prompting of these active safetys mainly for be that vehicle travels the relation with surrounding environment and designs, and driver can not be solved use the nonstandard problem of bearing circle.Particularly when fatigue driving, surface sees that chaufeur still controls bearing circle, but the dynamics that in fact grips reduces greatly, if there is emergency situation, is often caught unprepared, is easy to have an accident.
Summary of the invention
For prior art above shortcomings, the object of the present invention is to provide a kind of automobile active safety prompt system, when in vehicle travel process, if chaufeur can not grip bearing circle effectively, native system will provide alarm, thus improve drive safety.
To achieve these goals, the technical solution used in the present invention is such:
Automobile active safety prompt system, comprise bearing circle, be provided with on the steering wheel and detect the grip sensor whether chaufeur effectively grips bearing circle, described grip sensor is made up of several, all grip sensor are uniformly distributed and are divided into independently two groups on steering wheel circumference, often group grip sensor is connected successively and is formed grip sensor group, and two grip sensor groups are symmetrically arranged when bearing circle is placed in the middle; Each wheel is provided with the wheel speed sensors for detecting vehicle wheel rotation, and the output of two grip sensor groups and wheel speed sensors connects signal acquisition process controller jointly, signal acquisition process controller Tip element taking alarm.
Because when staff grips bearing circle, certain gripping pressure and temperature can be produced to bearing circle, described actual grip sensor is temperature sensor or pressure sensor, once systems axiol-ogy reaches temperature or the pressure of setting to bearing circle, can show that staff is in grip state.
Described alarm unit comprises the combination instrument of audible alarm unit and band alarm icon.
Automobile provided by the invention, comprises aforesaid automobile active safety prompt system.
The present invention well solves the early warning function of driver's mal steer direction dish in startup procedure, driver is made the moment to have manipulated bearing circle, avoid the traffic accident because steer direction dish causes not in time as much as possible, reduce and avoid personnel's property damage, for safety trip provides guarantee.
Accompanying drawing explanation
Fig. 1-safety prompting system structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
See Fig. 1, upper as can be seen from figure, automobile active safety prompt system of the present invention, comprise bearing circle 1, bearing circle 1 is provided with and detects the grip sensor 2 whether chaufeur effectively grips bearing circle, described grip sensor 2 is made up of several, and all grip sensor 2 are circumferentially uniformly distributed at bearing circle 1 and are divided into independently two groups, often group grip sensor is connected successively and is formed grip sensor group, and two grip sensor groups are symmetrically arranged when bearing circle is placed in the middle.The output that each wheel 3 is provided with wheel speed sensors 4, the two grip sensor group and wheel speed sensors for detecting vehicle wheel rotation connects signal acquisition process controller 5, signal acquisition process controller 5 Tip element taking alarm jointly.Wheel speed sensors 4 is responsible for collection vehicle speed, judges whether vehicle is in operation with this.
Because common roadlice wheel is four, therefore four wheel speed sensors are had, add two grip sensor groups, always have six Signal transmissions to signal acquisition process controller, signal acquisition process controller then determines whether will send alarm according to the output situation of these six signals by the judgment rule pre-set.
Because when staff grips bearing circle, certain gripping pressure and temperature can be produced to bearing circle, so actual grip sensor is temperature sensor or pressure sensor, once systems axiol-ogy reaches temperature or the pressure of setting to bearing circle, namely show that staff is in grip state.
During actual arrangement grip sensor, both can be arranged in bearing circle just facing to the direction of chaufeur, also can be arranged in the outer of steering wheel circumference circumferentially.And whether effectively grip for detecting due to grip sensor, so its spacing can not be too large, though to ensure that the hand (as women) that normal adult is less grips time, also can be arrived by least one sensor sensing.
Described alarm unit comprises the combination instrument 6 of audible alarm unit and band alarm icon 7, namely on existing combination instrument 6, an alarm icon 7 is set up again, icon can be bearing circle moulding, similar with other alarm mode existing.
The present invention is by the signal acquisition process controller acquisition of signal situation different with all wheel speed sensors according to two grip sensor groups, and by the programmed decision pre-set, determine whether carry out alarm, concrete judgment principle is as follows,
1) when all wheel speed sensors all detect that the speed of a motor vehicle is zero, show that vehicle remains static, no matter whether two grip sensor groups have signal to input, and alarm unit does not carry out any alarm.
2) when wherein any one wheel speed sensors detects that the speed of a motor vehicle is greater than zero, system thinks that vehicle is in motoring condition, if two grip sensor groups have signal to export, alarm unit does not carry out any alarm; Other situation alarm unit all carries out alarm, and other situation comprises: (i) two grip sensor groups only have one group to collect signal; (ii) two grip sensor groups all do not collect signal.Under both of these case, combination instrument alarm figure beacon light is bright, sends chimes of doom simultaneously.All wheel speed sensors are not detected that the speed of a motor vehicle is all greater than zero to be in motoring condition basis for estimation as vehicle by the present invention, this is the problem due to wheel speed sensors reliability, may due to some or two wheel speed sensors because fault collect tach signal, and now vehicle, still in traveling, just avoids erroneous judgement thus.
Also may occur under considering some normal conditions that the condition meeting alarm is (as gear shift, hand is of short duration to be left), but these situations can disappear usually very soon, in order to meet the hommization of driving safety prompting, this situation should not carry out alarm, therefore the present invention has carried out time delay judgement before reporting to the police, namely carry out alarm and meet except the situation of setting except two grip sensor groups and all wheel speed sensors, also need the delay time that the situation of this setting reaches default, when arriving the delay time of presetting, the situation of this setting does not still disappear, then carry out alarm, otherwise do not carry out alarm.Can postpone several seconds (as 4-6 second) during actual design after signal received by controller sends chimes of doom again, is so just unlikely to system and frequently sends alarm.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
