Active anti-collision automatic brake control system of automobile and working method

Abstract

The invention discloses an active anti-collision automatic brake control system of an automobile and a working method. The active anti-collision automatic brake control system comprises a pedestrian information acquiring and processing module, a driving safety state judging module and an automatic control module. The method includes steps that acquiring information of the pedestrian before the automobile, judging the driving safety state and controlling automatically. The active anti-collision automatic brake control system of the automobile and the working method use the learning rate mu for integral I, use the learning rate mu for proportion P and use the learning rate mu<D> for differential D so as to facilitate regulating different weight coefficients, the online correction for weighting coefficients is not based entirely on a neural network learning algorithm but formulated according to the actual situation, so that the timeliness and precision requirements are better satisfied. According to the active anti-collision automatic brake control system, the control system with an upper layer and a lower layer is designed based on sliding-mode control and mono-neuron PID control, the system buffeting phenomenon is effectively inhibited, the outside interference is overcame, the automatic stopping control for preventing the vehicle colliding with the pedestrian is realized, and the vehicle driving safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of automobile active safety intelligent control, relates to a vehicle automatic braking control method, in particular to an automobile active anti-collision automatic braking control system and a working method. Background technique [0002] Automobile active anti-collision warning system has become a research hotspot at home and abroad. The automotive active collision avoidance system includes the following key technologies: driving information perception and processing, driving safety status judgment, vehicle dynamics modeling and control, and control execution technology. Considering that the main research goal of the current automobile active collision avoidance system is to use the vehicle in front as the collision avoidance target, the research purpose is mainly positioned to improve the driving safety of the vehicle, and does not reflect the active safety protection for traffic vulnerable groups such as pedestr...
