Intelligent brake control device and control method thereof

Abstract

The invention provides an intelligent brake control device and an intelligent brake control method of the intelligent brake control device, belongs to the technical field of automobiles and solves the problems that the automobile automatic brake is not intelligent, and the control precision is low. The device comprises a fuzzy controller, an electric brake mechanism, a radar sensor, an acceleration sensor and a brake pedal sensor, wherein the electric brake mechanism, the radar sensor, the acceleration sensor and the brake pedal sensor are connected with the fuzzy controller, the fuzzy controller receives precise acceleration signals transmitted by the acceleration sensor and precise relative distance signals transmitted by a radar and carries out scattering and fuzzy processing when brake signals are not received, meanwhile, corresponding fuzzy brake braking force signals are output according to a meta-rule base set in the fuzzy controller, and in addition, the fuzzy brake braking force signals are converted into precise braking force signals for controling the electric brake mechanism to realize the brake. The control method comprises the following steps of: A, obtaining the input quantity; B, obtaining fuzzy input variables through fuzzy processing; C, carrying out clearing processing. The device and the method have the advantages that high intelligence of the automatic brake is realized, and the erroneous judgment probability is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an intelligent brake control device and a control method thereof. Background technique [0002] Along with traffic increasingly busy, the automobile collision accidents that fatigue driving, drunk driving etc. cause occur frequently. Wherein, in the driving process, because the speed of the car is too fast, the driver also cannot brake the car in time because of misjudgment, thus causing rear-end collisions to be a common and frequent traffic accident. Sometimes the driver may step on the brakes and step on the accelerator by mistake because of his nervousness, and the consequences of traffic accidents caused by this are unimaginable. How to effectively prevent vehicle rear-end collision is an urgent problem to be solved. [0003] In order to prevent the occurrence of above-mentioned accidents, the Chinese patent literature discloses an automobile rear-end collision avoidance...

AI Technical Summary

Problems solved by technology

Although the content disclosed in the above patent enables the vehicle to automatically brake according to specific conditions during driving, the above disclosure is only aimed at the field of fuel vehicles, and has the following shortcomings: 1. The energy is not absorbed by feedback during the braking process, and the vehicle’s The energy utilization rate is low, which is extremely unfavorable to the driving range of the vehicle; 2. The control is carried out in real time according to the detection signal of the sensor, and the information of random changes such as vehicle speed, distance and acceleration has uncertainty. For machines that require precise execution, the judgment and control of brakes are often not precise enough, prone to misjudgment of automatic braking, and not smart enough; 3. The accuracy of the system's sensors and the number of installations directly affect the accuracy of automatic braking control , so that the system structure is relatively complex and the manufacturing cost is high
