Embodiment 1

[0053] An embodiment of the present invention provides a method for controlling the headlights of a vehicle. When the vehicle enters a preset type of road section, the on-board terminal of the vehicle calculates the first adjustment angle of the headlights of the vehicle, and adjusts the headlights according to the first adjustment angle. The illumination angle of the vehicle's headlights improves accuracy and reduces traffic accidents.

[0054] The execution subject of this method can be the vehicle-mounted terminal of the vehicle, see figure 1 , where the method includes:

[0055] Step 101: Obtain the location information of the vehicle;

[0056] Step 102: According to the location information, determine whether the vehicle enters a preset type of road section;

[0057] Step 103: If the vehicle enters a road section of a preset type, obtain the road information of the road section and the driving speed of the vehicle;

[0058] Step 104: Calculate the first adjustment angl...

Embodiment 2

[0076] An embodiment of the present invention provides a method for controlling the headlights of a vehicle. When the vehicle enters a preset type of road section, the on-board terminal of the vehicle calculates the first adjustment angle of the headlights of the vehicle, and adjusts the headlights according to the first adjustment angle. The illumination angle of the vehicle's headlights improves accuracy and reduces traffic accidents.

[0077] The execution subject of this method can be the vehicle-mounted terminal of the vehicle, see figure 2 , the method includes:

[0078] Step 201: Obtain the location information of the vehicle;

[0079] The vehicle-mounted terminal is installed with GPS (Global Positioning System, Global Positioning System) or BDS (BeiDou Navigation Satellite System, China Beidou Satellite Navigation System), and the vehicle-mounted terminal obtains the location information of the vehicle every preset time through GPS or BDS.

Abstract

The invention discloses a method and a device for controlling a headlight of a vehicle, belonging to the technical field of positioning. The method includes: acquiring the location information of the vehicle; determining whether the vehicle enters a preset type of road section according to the location information; if the vehicle enters the preset type of road section, acquiring the road information of the road section and the The driving speed of the vehicle; according to the road information and the driving speed, calculate a first adjustment angle of the headlight of the vehicle; adjust the irradiation angle of the headlight of the vehicle according to the first adjustment angle. The device includes: a first acquisition module, a determination module, a second acquisition module, a second acquisition module and a first control module. The invention improves the accuracy of calculating the first adjustment angle and reduces the occurrence of traffic accidents.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a method and a device for controlling a headlight of a vehicle. Background technique [0002] When the vehicle is driving in the dark, the driver turns on the headlights of the vehicle to illuminate the road area in front of the vehicle. However, even if the headlights are turned on, the accident rate at night is much higher than that during the day, especially on curves or slopes. On special road sections such as roads, the accident rate is higher due to the deviation of the irradiation range of the headlights of the vehicle and the road surface. Therefore, when the vehicle is driving on a special road section such as a curve or a slope, the irradiation range of the headlight of the vehicle is controlled to be consistent with the road surface, so as to reduce the occurrence of traffic accidents. [0003] At present, the method for controlling the headlights of the vehicle m...
