Abstract
The utility model relates to automobile emergency brake alarming device, comprise microprocessor and acceleration pick-up, the signal output part of this acceleration pick-up connects AD, the mouth of this AD connects described microprocessor, the signal input part of this microprocessor is connected with speed-slackening signal input terminal, described output end of microprocessor connects warning driving circuit, this warning driving circuit drived control emergency braking caution device; Microprocessor of the present utility model is that the acceleration information uploaded according to acceleration pick-up carries out judging whether to be in emergency braking condition, corresponding caution device is then driven to send the warning of emergency braking to rear car if be in emergency braking condition, make rear car chaufeur have the more time to take measures, avoid the generation of rear-end collision.
Description
Technical field
The utility model belongs to the emergency braking technical field of vehicle, relates to a kind of automobile emergency brake alarming device.
Background technology
With the development of person society, automobile is more and more universal in China, the recoverable amount of automobile increases gradually, but along with the quick increase traffic accident of automobile quantity is also in increase, traffic accident causes a large amount of personnel, property damage, and one of reason causing traffic accident is front vehicles emergency braking, rear power actuated vehicle, non-power-driven vehicle are failed to hide in time and are caused and to knock into the back and the chain of rings such as to knock into the back at the accident.Existing automobile brake system can not distinguish emergency brake and general brake, as long as step on brake pedal, the brake display lamp of the tailstock will be bright, but vehicle below cannot judge whether it is emergency brake according to brake display lamp, if emergency brake is mistaken for general brake, probably there is rear-end collision, actv. treatment measures can not be taked in advance to avoid the generation of accident, therefore a kind of device can reminded to the power actuated vehicle of rear view of vehicle, non-power-driven vehicle is needed, to avoid the generation of the rear-end collision caused because of front vehicles emergency braking.
Utility model content
The purpose of this utility model is to provide a kind of automobile emergency brake alarming device, cannot provide effective warning of emergency braking to solve existing apparatus and cause the problem of traffic accident.
For achieving the above object, automobile emergency brake alarming device technical scheme of the present utility model is as follows: comprise microprocessor and acceleration pick-up, the signal output part of this acceleration pick-up connects AD, the mouth of this AD connects described microprocessor, the signal input part of this microprocessor is connected with speed-slackening signal input terminal, described output end of microprocessor connects warning driving circuit, this warning driving circuit drived control emergency braking caution device.
Further, the signal input part of described microprocessor is also connected with left and right turn sign input terminal.
Further, described emergency braking caution device is sound, light and/or electric equipment.
Microprocessor in automobile emergency brake alarming device of the present utility model is that the acceleration information uploaded according to acceleration pick-up carries out judging whether to be in emergency braking condition, corresponding caution device is then driven to send the warning of emergency braking to rear car if be in emergency braking condition, make rear car chaufeur have the more time to take measures, avoid the generation of rear-end collision.
Accompanying drawing explanation
Fig. 1 is the device block diagram of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, automobile emergency brake alarming device comprises Freescale Multifunctional microprocessor MM908E625 and acceleration pick-up MMA7260Q, the signal output part of this acceleration pick-up connects AD, the mouth of this AD connects microprocessor, the signal input part of this microprocessor is connected with speed-slackening signal input terminal, left direction signal input terminal and right steering signal input terminal, output end of microprocessor connects warning driving circuit, this warning driving circuit drived control emergency braking caution device, this emergency braking caution device is sound, light and/or electric equipment, in the present embodiment, emergency braking caution device is the adjustable car light of flicker frequency.Microprocessor reads acceleration/accel and deceleration/decel data from acceleration pick-up, after microprocessor judges process, as vehicle is in urgent state processed, then drive corresponding lighting system, left and right turn signal is allowed to light, as shown in fig. 1, microprocessor has also inputted brake switch signal, left steering on-off signal and right on-off signal, these three signals are used for providing to microprocessor and confirm currently whether be in braking mode, simultaneously as located steering indicating light open mode, then automatically can improve the flicker frequency of steering indicating light.
