Auxiliary automobile lighting system based on GPS navigation device

Abstract

The invention provides an auxiliary automobile lighting system based on a GPS navigation device. The auxiliary automobile lighting system comprises the GPS navigation device, an acceleration sensor, alight sensor, two lateral side lighting units and an electronic control unit. The GPS navigation device is used for obtaining current position information of an automobile in real time; the acceleration sensor is used for obtaining acceleration information of automobile traveling in real time; the light sensor is used for obtaining the outside light intensity in real time; the two lateral side lighting units are arranged on the two sides of an automobile body respectively; the electronic control unit is used for determining the movement track of the automobile according to the position information obtained when the automobile reaches a preset range A and the obtained acceleration information; when the outside real-time light intensity is lower than a first threshold value B, the longitudinal acceleration is a negative value, and the transverse acceleration is larger than 0, the lateral side lighting unit on the corresponding side is turned on according to the steering direction or theturning direction, lighting is conducted in a preset range away from one side of the automobile body, and objects within the preset range are presented to a driver through rearview mirrors.

Description

technical field [0001] The invention relates to a motor vehicle lighting system, in particular to an automotive auxiliary lighting system based on a GPS navigation device. Background technique [0002] Please refer to figure 1 At present, when a car drives at night, it is illuminated by the headlights arranged in front of the car. After the headlights are turned on, they can only illuminate the road directly in front of the car. Therefore, when the car is turning at night, especially when the light is very bright When turning at a dark intersection, due to insufficient lighting on one side of the vehicle body, it is difficult for pedestrians or bicycles within a certain range (blind spot D) on the side of the vehicle body to be presented to the driver through the rearview mirror. When the speed is about to pass through the intersection, it is easy to collide with the turning car. Contents of the invention [0003] The invention provides an auxiliary lighting system for a...
