Safety traffic is inevitable topic during automobile uses all the time, in recent years, along with the increase of car owning amount and improving constantly of the speed of a motor vehicle, traffic accidents also presents the trend increased year by year, and due to the raising of the speed of a motor vehicle, it is comparatively large that traffic accident also shows injures and deaths, loses higher feature.Therefore, improving brake system of car performance is reduce traffic accident, avoids the effective way of personal casualty and property damage.
The brake system of automobile depends on braking clamp friction brake disk, the rotation of limiting wheel, thus make frictional ground force contrary with automobile working direction, the braking force of car deceleration is provided, after the braking through a segment distance, realizes automobile by the transition process of high-speed motion state to quiescence.The braking procedure of orthodox car makes to obtain maximum braking force during automobile brake by locking tire, but the vehicle after tire locking to turn to etc. handling owing to losing, and easily causes the phenomenons such as sideslip, whipping, and then causes the generation of traffic accident; The ABS antiblock device of widespread use is in recent years on the basis of orthodox car, adopt the way automatically controlled, prevent the locking of braking procedure tire, lose the control to operability, simultaneously as much as possiblely again provide braking force, well solve the handling problem in automobile brake, then ABS antiblock device but can not shorten stopping distance, relative to locking system in a lot of situations even, on the contrary can increase stopping distance to a certain degree, and avoiding of accident and alleviating of injuring under being unfavorable for emergency braking situation.
Therefore, on the basis of ABS antiblock device, shortening stopping distance as much as possible seems particularly important, better can avoid personal casualty in an emergency braking situation and reduce property damage.
Summary of the invention
The technical matters that when the purpose of this utility model is the ABS system works overcoming existing automobile, stopping distance is longer, provides a kind of automobile brake auxiliary device, and it, when ensureing automobile balance braking, shortens stopping distance.
In order to solve the problem, the utility model is achieved by the following technical solutions:
A kind of automobile brake auxiliary device of the present utility model, comprise microprocessor, detect the degree of dip detection module of the acceleration pick-up of pickup and detection automobile head degree of dip, described microprocessor is electrically connected with the ABS system of acceleration pick-up, degree of dip detection module, automobile and the electro-hydraulic brake mechanism of automobile respectively.
In the technical program, ABS system starts, and ABS system is taked to send control signals to microprocessor during braking at every turn.After microprocessor receives control signal, the deceleration/decel size of automobile is detected by acceleration pick-up, the downward-sloping angle of headstock is detected by degree of dip detection module, the amplitude of headstock sinking is gone out according to the change calculations of headstock downtilt angles, the hydraulic coupling size that need apply is found by tabling look-up according to car deceleration degree and headstock sinking amplitude, and sending it to electro-hydraulic brake mechanism, electro-hydraulic brake mechanism applies pressure according to the pressure data received to wheel.
Under pressure, the maximum frictional force on wheel and ground increases, and headstock sinks under this application force, in braking procedure, according to the adjustment of headstock sinking amplitude, electro-hydraulic brake mechanism can effectively avoid headstock sinking amplitude excessive to the application force that wheel applies, and ensures automobile balance braking.In guarantee automobile balance braking procedure, strengthen the braking force that electro-hydraulic brake mechanism applies as far as possible, make each ABS system point braking force in a flash large as much as possible, shorten stopping distance, that avoids some originally can occur slightly knocks into the back, collides and scraping etc., simultaneously because braking deceleration effect increases, the reduction of speed also can alleviate the personal injury and property damage that suffer when unavoidable collision produces.
As preferably, described degree of dip detection module is obliquity sensor.
As preferably, described degree of dip detection module is arranged on automobile head position.
As preferably, described a kind of automobile brake auxiliary device also comprises car speed sensor, voice output module and the apomecometer for the spacing that detects automobile and front vehicles, described apomecometer is arranged on automotive front end, described voice output module installation is on vehicle console, and described car speed sensor, voice output module and apomecometer are electrically connected with microprocessor respectively.Microprocessor calculates the safety distance between automobile and front vehicles according to automobile speed, if the distance that apomecometer detects is less than safety distance, then Microprocessor S3C44B0X voice output module exports voice message, reminds chaufeur braking deceleration.
As preferably, described a kind of automobile brake auxiliary device also comprises the rain sensor be arranged on automobile, and described rain sensor is electrically connected with microprocessor.When rainy, road surface slippery situation, the friction force on tire and ground reduces, and therefore safe distance between vehicles will strengthen, between the real-time vehicles of rainfall that microprocessor detects according to rain sensor and front vehicles safety distance threshold value, be convenient to remind chaufeur braking deceleration to remain a safe distance behind the car in front in time.
The beneficial effects of the utility model are: (1) is when ensureing automobile balance braking, strengthen the braking force that electro-hydraulic brake mechanism applies as far as possible, shorten stopping distance, that avoids some originally can occur slightly knocks into the back, collides and scraping etc., simultaneously because braking deceleration effect increases, the reduction of speed also can alleviate the personal injury and property damage that suffer when unavoidable collision produces.(2) chaufeur braking deceleration can be reminded in time to remain a safe distance behind the car in front.
