Vehicle light control method for adaptive front lighting system

Abstract

The invention discloses a vehicle light control method for an adaptive front lighting system. The method comprises the following steps of: determining the vehicle light turning angle of the adaptive front lighting system (AFS) by using an accelerator pedal, a brake pedal, a clutch pedal, a gear, a steering wheel turning angle and the height information of a front axle and a back axle; simulating the attitude and the speed of a vehicle according to the characteristics of an AFS kinetic model, and acquiring the turning angle of a vehicle light by combining different vehicle types and road conditions; creating a language control rule by combining the empirical ranges of the left, right and longitudinal turning angles of a front light, and performing fuzzy reasoning and constructing a fuzzy control rule table according to the language control rule; and acquiring a fuzzy output decision by calculating a fuzzy relationship, and acquiring the actual control quantity of a vehicle light turning angle through defuzzification so as to output a motor control value to a motor driving module.

Description

technical field [0001] The invention relates to a light control algorithm of an automobile self-adaptive headlight system based on information such as an accelerator pedal, a brake pedal, a clutch pedal, a gear position, a steering wheel angle, and heights of front and rear axles. Background technique [0002] At present, the headlight system of a vehicle is mainly composed of low beams, high beams, running lights and front fog lights. When the car is driving on urban roads and at the speed limit, the low beam is mainly used; when driving at high speed on country roads or expressways, the high beam is mainly used; when driving in foggy weather, the fog lights should be turned on; Running lights (European standard). But in actual use, there are many problems in the traditional headlight system. For example, the short-range lighting effect of existing low beam lights is very bad. When the traffic situation is more complicated, drivers often turn on the low beam lights, high ...

AI Technical Summary

Problems solved by technology

For example, the short-range lighting effect of existing low beam lights is very bad. When the traffic situation is more complicated, drivers often turn on the low beam lights, high beam lights and front fog lights; Seriously affect the driver's judgment of obstacles on the curve; when the vehicle is driving in rainy days, the water on the ground reflects the light of the headlights, resulting in reflected glare, etc.
