Safety intelligent brake method and system for automobile

Abstract

The invention relates to a vehicle intelligent security brake method and the system thereof. The system comprises a signal detection unit for detecting an emergency brake signal for the emergency emergent brake and sending the emergency brake signal, and an anti-lock brake device mainly comprising an electronic control unit, an anti-lock brake execution device and a hydraulic brake device. The anti-lock brake device comprises a pressure accumulator and a hydraulic pump for boosting the pressure accumulator. The electronic control unit is used for receiving the emergency brake signal from the signal detection unit and converting the emergency brake signals into an initial signal, and then initiating the control of the pressure accumulator to complete the emergency brake under the pressure inside the pressure accumulator. The electronic control unit can change the control time sequence of the hydraulic pump and the pressure accumulator, so as to control the pressure relief of the pressure accumulator prior to the pressure supply to the hydraulic pump. Therefore, the initial speed of the system is increased, the performance of the system is enhanced, and the traffic accident is efficiently prevented.

Description

(1) Technical field [0001] The invention relates to an automobile safety protection system, in particular to an automobile safety intelligent braking method and system. (2) Background technology [0002] When the car encounters sudden and unpredictable situations such as car tire blowout and collision, the car will lose control in a very short period of time. A slight negligence, failure to control the steering wheel, and emergency braking will cause accidents. At this time, the driver is often unable to brake in time due to nervousness or untimely operation, and may even step on the accelerator by mistake in a panic. huge loss. If the automobile can immediately start the braking device when there is an emergency, it can effectively avoid traffic accidents caused by reaction barriers formed by human physiological limitations. [0003] In order to solve the above problems, a Chinese utility model patent with the announcement number of CN2905577Y published on May 30, 2007 pr...

AI Technical Summary

Problems solved by technology

If the driver cannot adjust the steering wheel to change the running direction of the car during this period of time and distance, the purpose of emergency avoidance cannot be achieved, and the danger still exists.

Furthermore, in some cases, there is no need to turn off the flame, such as when reversing, anti-rear collision, etc., but only emergency deceleration is needed. If the ignition system and fuel injection circuit on the car are cut off suddenly, the driver will feel unable to adapt, and It also needs to be re-ignited to start the car, which increases the complexity of the car's operation. If such a situation occurs on the highway, the sudden shutdown of the car is very dangerous
