Intelligent car light control method and system

Abstract

The invention relates to the technical field of automobile illumination, in particular to an intelligent automobile lamp control method and system. The intelligent automobile lamp control method comprises the steps that according to a navigation system, whether an automobile needs to switch the current driving state or not is judged; under the condition that the automobile needs to switch the driving state, the steering preparation distance between the current position of the automobile and the next driving state starting point is worked out; and whether the steering preparation distance is matched with a threshold distance or not is judged, and under the condition that the steering preparation distance is no larger than the threshold distance, a light-compensating lamp is turned on. Before the driving state is switched, light compensation and illumination are conducted on a road on which the automobile is to travel through the light-compensating lamp, that is the illumination mode that illuminating is conducted before driving is adopted, and the situation that when a user enters a new road, visual inertia is caused, and driving safety is affected is avoided; and in addition, in the whole driving state switching process, the illuminating direction of a main illuminating lamp is not changed, that is in the design process of the main illuminating lamp, an adaptive front lighting system (AFS) does not need to be arranged, and the manufacturing cost of the illuminating system is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle lighting, and in particular to a method and system for controlling an intelligent vehicle light. Background technique [0002] With the development and progress of technology, the existing high-end vehicles are equipped with adaptive front-light control system AFS (Adaptive Front-lighting System, AFS), adaptive front-light control system AFS, consists of four parts: sensor, ECU, light control system and headlights. The vehicle speed sensor and the steering wheel angle sensor continuously transmit the detected signals to the ECU, and the ECU processes the signals detected by the sensors, judges the processed data, and outputs the headlight rotation angle command to make the headlights rotate corresponding angle. The system uses the vehicle speed detected by the vehicle speed sensor, and uses the steering angle detected by the steering wheel angle sensor to detect the steerin...

Problems solved by technology

This solution uses GPS to obtain whether there is a curve in the next road section. If it is a curve, the car light mode of the next road section is calculated and configured through the navigator and transmitted to the AFS car light module. The AFS car light module controls the lighting direction of the headlight. Adjustment, this adjustment method uses the steering angle detected by the steering wheel angle sensor to detect the steering angle of the steering wheel, which has obvious hysteresis. At the same time, after the AFS lights adjust the lighting direction, the original lighting direction is not bright enough, which is not conducive to driving at night. At the same time, the manufacturing cost of AFS lights is relatively high
