Abstract
The utility model provides a control system for reducing an emergency brake distance. The control system comprises a liquid storage tank controlled by an ECU (Electronic Control Unit), a front high-pressure liquid spray pump, a sensing and remote sensing device, a rear high-pressure liquid spray pump and a cleaning solvent spray device, wherein the liquid storage tank, the front high-pressure liquid spray pump, the sensing and remote sensing device, the rear high-pressure liquid spray pump and the cleaning solvent spray device are connected through oil pipes. The control system provided by the utility model solves the technical problem that the conventional braking device is insensitive in brake in case of an emergency and initiatively improves the safety protection measures.
Description
Technical field
The utility model belongs to the automobile brake field, is specifically related to a kind of reduction emergency stopping distance control system.
Background technology
When running into the emergency braking situation, begin to brake the stopping distance that stops from chaufeur and determining whether can evade safely the casualty accident generation.Traditional brake system stopping distance has become a bottleneck, because the friction coefficient between ground and the tire has determined braking force, so should start with from changing friction coefficient, but from present technology, take the reasonable distribution braking force to reduce stopping distance mostly, rarely having progress aspect the change friction coefficient.Current automotive technology is very high to safety requirements, and changes active safety into from the passive security pattern, and this invention to the active safety protection highly significant.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of reduction emergency stopping distance control system.
The reduction emergency stopping distance control system that the utility model provides comprises fluid reservoir, the preceding high pressure Liquid spraying pump by ECU control, sensing and sensoring, back high pressure Liquid spraying pump, and cleaning solvent sprinkler, wherein fluid reservoir, the preceding high pressure Liquid spraying pump of ECU control, sensing and sensoring, back high pressure Liquid spraying pump, and the cleaning solvent sprinkler is connected by oil pipe.
The utlity model has following advantage:
Stopping distance has become a limit that is difficult to breakthrough, it also is the root of a lot of traffic accidents, be head it off, can be when emergency braking spray simultaneously the very high fluent material of tire and road surface stickness to increase the resistance and the adhesive ability of automobile to tire protector and road surface.When spraying,, spray automatically when being chosen in emergency braking by sensor and electronic unit control; Spraying the position, spray to road surface and tire simultaneously wheel cover top and both sides, front and back; Post-processing makes tailstock dilution, can eliminate the influence of road pavement.Thereby initiatively improve safety precautions.

The 1-fluid reservoir; High pressure Liquid spraying pump before the 2-; 3-sensing and sensoring; 4-ECU; High pressure Liquid spraying pump behind the 5-; 6-cleaning solvent sprinkler.
The specific embodiment
This system that the utility model provides comprises fluid reservoir, the preceding high pressure Liquid spraying pump by ECU control, sensing and sensoring, back high pressure Liquid spraying pump, and cleaning solvent sprinkler, wherein fluid reservoir, the preceding high pressure Liquid spraying pump of ECU control, sensing and sensoring, back high pressure Liquid spraying pump, and the cleaning solvent sprinkler is connected by oil pipe.Wherein fluid reservoir is arranged in machinery space inside, and liquid storage dosage stores according to quantity according to test results, needs behind the one-shot usage to change.The high pressure Liquid spraying pump is controlled hydrojet by ECU.The flowing power of sticker in pipeline need be carried out chemical treatment, can guarantee its flowing power in pipeline, the viscosity after guaranteeing again to spray.The quantitative data input of ECU is imported by sensor, and sensor mainly is the emergency braking situation and the speed of a motor vehicle of sense vehicle.At last, the liquid of ejection can be cleaned by the cleaning solvent that vehicle carries.When vehicle in emergency braking and current braking force deficiency so that vehicle under the situation of stopping in the safety distance, car speed sensor and sensoring are imported ECU to signal, analyze this situation and may take place through ECU, the high pressure Liquid spraying pump sprays the liquid material that the road pavement that is stored in the fluid reservoir and tire have very strong binding force to tire periphery and road surface before and after ECU control this moment.This material at first increases the adhesive ability between wheel and road surface, thereby can increase the preceding lock torque of wheel lockup, makes brake braking force can bring into play better effect, and locking is lagged behind; Secondly this material is piled up on road surface and vehicle joint place, and wheel is produced a reverse resisting moment; Most importantly cohesive material can strong increase wheel and ground-surface binding power, and vehicle can consume a lot of energy when overcoming this power.By the effect of above three kinds of power, car is stopped in short distance.For ensure this operating process road pavement and afterwards vehicle impact, cleaning solvent is equipped with in portion at the tailstock, simultaneously the sticker on the road pavement cleans.
