Description
Technical field
The utility model relates to a kind of general vehicle illumination or signalling apparatus, relates to a kind of device that is used to indicate brake action particularly.
Background technology
At present, common vehicle brake lamp generally rearward vehicle show that this car brakes, can not demonstrate this car is normal braking or emergency brake, promptly can't judge the dynamics of brake, the vehicle drivers at rear is owing to can not judge the braking state of front vehicles rapidly accurately, can only according to the stoplight stop lamp of front vehicles light and two cars between distance judge, therefore be easy to cause rear-end collision.In order to reduce the generation of rear-end collision, people can utilize sensing element to predict in the brake process size of pressure in the brake pump housing or the brake oil pipe, be converted into electric signal, pass to stoplight stop lamp again, make stoplight stop lamp send the optical signal of different brightness, thereby can point out the speed of braking automobile clearly.
But said method all exists certain defective: if at first directly predict oil pressure in the brake oil pipe, certainly will to destroy brake oil pipe integrative-structure, cause the leakage of oil of brake fluid line pipe if seal bad meeting, braking quality is affected; In addition, in predicting the brake pump housing, during pressure big or small, need in car body, be provided with optional features such as pressure inductor, make the vehicle inside structure become complicated.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that exists in the existing braking strength indicating device, it utilizes the element in the existing automobile, pass through control system, make stoplight stop lamp or stoplight stop lamp group under different braking strengths, send different optical signals, this apparatus structure is simple, and is easy for installation, need not to be provided with in automobile other pressure inductor, and can accurately predict the braking strength of automobile, have the effect of good indication braking strength.
The utility model is to adopt following technical scheme to realize: a kind of braking strength indicating device, comprise the signal link between vehicle wheel rotational speed inductor and this inductor and the ABS assembly, wherein, on the signal link between vehicle wheel rotational speed inductor and the ABS assembly line interface is set, this line interface is provided with three interfaces at least, one of them interface is connected with the vehicle wheel rotational speed inductor by signal link, an interface is connected with the ABS assembly by signal link, and the 3rd interface is connected with the braking strength analysis system by signal link.
In the utility model, described braking strength analysis system is made up of waveform shaping circuit, one-chip computer and DA conv.This braking strength analysis system is connected with stoplight stop lamp or stoplight stop lamp group.
In the automobile that has the ABS assembly, the ABS assembly generally is connected with the vehicle wheel rotational speed inductor by signal link, and the vehicle wheel rotational speed inductor shows the rotating speed of the wheel form with impulse singla.By line interface is set on signal link, can draws an other bars line from this interface and be connected with the braking strength analysis system.After impulse singla enters this analysis system, at first this impulse singla is converted into the square-wave signal of standard by waveform shaping circuit, square-wave signal is through obtaining the cireular frequency and the angular acceleration of wheel after the analytical calculation of one-chip computer, thereby learn the rate of braking of automobile, these strength rating are converted into electric signal by the DA conv, and the stoplight stop lamp of direct control automobile or stoplight stop lamp group, the rate of braking value is big more, and electric signal is strong more.Therefore at different braking states, the power that can represent braking strength by the optical signal that stoplight stop lamp or stoplight stop lamp group are sent different brightness, also can show, perhaps utilize different electric signal that the stoplight stop lamp of different colours or stoplight stop lamp group are lighted respectively by the number difference that stoplight stop lamp or stoplight stop lamp group light.
The beneficial effects of the utility model are, this device has made full use of the element that automobile carries, and need not to be provided with other add ons such as pressure sensor, has simplified the inner structure of automobile, and can point out the speed of braking automobile clearly, the generation of minimizing accident effectively.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this device comprises vehicle wheel rotational speed inductor 1, the signal link 2 between vehicle wheel rotational speed inductor 1 and the ABS assembly 5, line interface 3 and braking strength analysis system 4.Line interface 3 wherein is set on pulse line 2, three interfaces are set on the line interface 3, one of them interface is connected with vehicle wheel rotational speed inductor 1 by signal link 2, another interface is connected with ABS assembly 5 by signal link 2, and the 3rd interface is connected with braking strength analysis system 4 by signal link 2.Braking strength analysis system 4 mainly is made up of waveform shaping circuit, one-chip computer and DA conv.Waveform shaping circuit wherein can be converted to impulse singla the square-wave signal of standard.
Vehicle wheel rotational speed inductor 1 is installed on the change-speed box, transmission output shaft rotates by the rotor shaft that driven gear drives wheel speed sensor 1, rotor shaft can produce impulse singla when rotating, this impulse singla is connected with ABS assembly 5 by signal link 2, in brake process, when the vehicle wheel rotational speed signal determining that the electronic control package in the automobile is imported according to wheel speed sensor 1 had wheel to be tending towards locking, ABS just entered anti-lock brake pressure control process.By on 5 signal link 2 between wheel speed sensor 1 and the ABS assembly line interface 3 being set, the impulse singla that wheel speed sensor 1 is produced enters in the braking strength analysis system 4 simultaneously.After impulse singla enters this system, at first pass through waveform shaping circuit, impulse singla is converted to the square-wave signal of standard, this square-wave signal can obtain the cireular frequency and the angular acceleration of wheel through the analytical calculation of one-chip computer and related software, thereby learn the rate of braking value of this automobile, the rate of braking value is converted to electric signal by the DA conv.In the brake process, difference along with braking strength, the power of analyzing the electric signal that produces after converting system 4 conversions through braking strength is also different, the power of this electric signal can be by stoplight stop lamp or stoplight stop lamp group the optical signal of the different brightness of being sent show, also can show by the number that stoplight stop lamp under the different braking states or stoplight stop lamp group light, perhaps different electric signal lights the stoplight stop lamp of different colours or stoplight stop lamp group respectively.
In the utility model, the interface more than three can be set also on the line interface.In addition, line interface both can only be arranged on the signal link between a vehicle wheel rotational speed inductor and the ABS assembly, also can be arranged on simultaneously on the signal link between four vehicle wheel rotational speed inductors and the ABS assembly, perhaps on the signal link between part vehicle wheel rotational speed inductor and the ABS assembly, line interface is set.
