Abstract
The utility model discloses a slow and emergency braking light warning device. The slow and emergency braking light warning device comprises a sensor arranged below a brake pedal; the sensor is connected with a central control unit; the central control unit is connected with a driving circuit; the driving circuit is connected with a braking lamp controlled by the central control unit and is also connected with a screen type display; and the central control unit comprises a singlechip control system used for changing the twinkling frequency of the braking lamp according to the duration of braking time and the braking strength. The slow and emergency braking light warning device has a simple structure and is convenient to use; the braking lamp is arranged and twinkles to catch the attention of following vehicles, and the twinkling frequency can be changed according to the braking strength, so that the following vehicles can clearly know the braking condition of ahead vehicles, and accidents can be reduced.
Description
Technical field
The utility model relates to a kind of brake light control setup, is the slow brake light alarming device of a kind of urgency concretely.
Background technology
At present, the brake light function singleness of existing vehicle is when brake of motor-driven vehicle; The rear brake lamp is luminous, to cause front vehicle and pedestrian's attention, as long as existing stoplight stop lamp is stepped on brake; Stoplight stop lamp is just lighted, and can not demonstrate braking strength information, in the vehicle ' process; Front truck takes emergency braking easily the back car to be caused great danger, and particularly in city vehicle relatively crowded highway section and the occasion that can not guarantee spacing, back vehicle is when the emergency brake of front truck emergency situations; Be difficult to judge its braking strength, judge inaccurate frequent passive emergency brake, cause the generation of rear-end collision easily.In order to address this problem, take stoplight stop lamp to be set to a row in the prior art, show the stoplight stop lamp of different numbers according to the difference of car retardation degree, system principle and complex structure like this, actual use inconvenience has also increased cost.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art; Provide a kind of simple in structure; Easy to use, the stoplight stop lamp flicker is provided with, thereby reminds front vehicle to note; And can change flicker frequency, thereby be convenient to the slow brake light alarming device of urgency of the clear and definite front truck brake of front vehicle situation according to the braking strength size.
Its technical scheme is: anxious slow brake light alarming device; Comprise the sensor that is arranged on the brake pedal below; Said sensor is connected with central controller; Said central controller is connected with driving circuit, and said driving circuit is connected with through the stoplight stop lamp of central controller controls and screen-type telltale, and said central controller comprises the single-chip computer control system that is used for changing according to brake time length and braking strength the stoplight stop lamp flicker frequency.
Said sensor is a pressure sensor.
Single-chip computer control system comprises respectively and said driving circuit bonded assembly gently brake electronic control switch, sudden stop electronic control switch and emergency brake electronic control switch.
After having adopted technique scheme; The beneficial effect that the utility model is obtained is: the utility model is simple in structure, and is easy to use, and the stoplight stop lamp flicker is provided with; Thereby remind front vehicle to note; And can change flicker frequency according to the braking strength size, thus be convenient to the clear and definite front truck brake of front vehicle situation, reduced the generation of accident.
Description of drawings
Accompanying drawing is the control principle figure of system of the utility model embodiment.
The specific embodiment
Shown in accompanying drawing; Anxious slow brake light alarming device; Comprise the sensor that is arranged on the brake pedal below, said sensor is connected with central controller, and said central controller is connected with driving circuit; Said driving circuit is connected with through the stoplight stop lamp of central controller controls and screen-type telltale, and said central controller comprises the single-chip computer control system that is used for changing according to brake time length and braking strength the stoplight stop lamp flicker frequency.
Said sensor is a pressure sensor.
Single-chip computer control system comprises respectively and said driving circuit bonded assembly gently brake electronic control switch, sudden stop electronic control switch and emergency brake electronic control switch.
Wherein, Single-chip computer control system is through programming its mode register to be set; Can be set at needed mode of operation, the single-chip computer control system of measuring the braking strength parameter according to pressure sensor and being sent to central controller like light when brake carries out data handing, and through the light brake of single-chip computer control system control electronic control switch; Thereby the connection driving circuit, thereby can control stoplight stop lamp for not dodging state; In like manner, connect the sudden stop electronic control switch during sudden stop, stoplight stop lamp is a blink states; And connect the emergency brake electronic control switch during emergency brake, stoplight stop lamp is the fast blink state.In addition, can drive screen display by certain function program through central controller.Can be set in connection, the disconnection of output port under a certain dynamics value according to central controller; And can configure the flicker frequency that the external trigger frequency is controlled stoplight stop lamp in advance; Thereby can control the speed degree of stoplight stop lamp flicker according to the size of braking strength, certainly, also can pre-set timing; Will touch switch when brake reaches this time, the flicker frequency of control flash light.Be provided with through flicker, can improve the attention of front vehicle, be convenient to front vehicle and make judgement fast.
During use; Supply power through power brake source, when central controller receives the detected brake signal of vehicle sensors, measure the braking strength parameter and be sent to central controller by pressure sensor and carry out data handing; According to central controller it is differentiated; Confirm it is light brake, sudden stop or emergency brake, and corresponding output drive signal, thereby corresponding brake electronic switch is started by the drive signal of single-chip computer control system output; Thereby cooresponding driving circuit is connected, and carries out light-emitting flash and shows.Through being Rule of judgment with brake time length, make vehicle produce different show states such as general braking state or emergency brake state, to improve the attention to front vehicle, guarantee driving safety property, the generation of reduction accident with braking strength.And need not to change position and the quantity that has stoplight stop lamp now, reduced cost.
The utility model is simple in structure, and is easy to use, and the stoplight stop lamp flicker is provided with, and can remind front vehicle to note, and can change flicker frequency according to the braking strength size, thereby is convenient to the clear and definite front truck brake of front vehicle situation, reduced the generation of accident.
