Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] As an embodiment of the present invention, such as figure 1 The overtaking warning control system based on fuzzy control shown includes:

[0040] The input quantity obtaining unit 101 obtains the vehicle steering switch state, and the distance value between the vehicle and the right front vehicle as the input quantity of the fuzzy controller 102;

[0041] The fuzzy controller 102 receives and performs fuzzy processing on the state of the steering switch and the distance value, obtains the corresponding fuzzy input quantities T and L, and searches the preset fuzzy control rule table according to the fuzzy input quantities T and L Obtain the precise control amount; specifically, calculate and obtain the fuzzy input quantity T according to the preset first membership function table according to the state of the steering switch, and obtai...

Abstract

The invention discloses an overtaking early-warning control method based on fuzzy control and a corresponding system, wherein the overtaking early-warning control method based on the fuzzy control comprises: obtaining a steering switch state and a distance value between a vehicle and a vehicle at the right front of the vehicle as an input quantity; computing according to a preset first membership function table to obtain a fuzzy input quantity T according to the steering switch state, and computing according to a preset second membership function table to obtain a fuzzy input quantity L according to the distance value; searching a preset fuzzy control rule table according to the fuzzy input quantities L and T to obtain an accurate control quantity; and determining whether to perform an overtaking pre-warning or not according to the accurate control quantity. By utilizing the overtaking early-warning control method and system based on the fuzzy control, a left turn signal light is automatically turned on in advance during overtaking, the overtaking without turning on the left turn signal light due to a bad driving habit of a driver is avoided, and the traffic safety factor is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an overtaking early warning control method and system based on fuzzy control. Background technique [0002] With the continuous increase of car ownership, road traffic conditions have become more complex, followed by more and more traffic accidents. The number of traffic accidents caused by overtaking accounts for a considerable amount of all traffic accidents. percentage. Many drivers habitually forget to turn on the turn signal in advance to remind the vehicle in front when overtaking. This bad driving habit is an important factor causing overtaking traffic accidents. [0003] The overtaking reminder or early warning device in the prior art is mainly to install a signal transmitter and a signal receiver on the vehicle. When overtaking is desired, the signal transmitter is used to send an overtaking signal, and when the signal receiver receives the overtaking signal, a remi...
