Embodiment Construction
[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific drawings.
[0019] The main purpose of the present invention is to analyze the demand for vehicle headlamp lighting for safe driving of existing vehicles when turning, and aim at the fact that existing vehicles cannot control the lighting state of the headlights according to the turning state during the turning process. The problem of adjustment is to provide a predictive follow-up control method for vehicle headlights.
[0020] figure 1 The state shown is the state of the vehicle turning left (the situation of turning right is similar), the lighting direction of the vehicle's headlights is along the direction of the vehicle body without any adjustment. When the vehicle turns to the left, the headlights should be deflected to the left relative to the body for driving sa...

The invention discloses a predictive follow-up control method for vehicle headlamps, and aims to overcome the shortcoming of incapability of regulating the illumination state of conventional vehicle headlamps according to a current steering state and requirements on the safe running of the vehicle in a steering process of a vehicle. The control method comprises the following steps of acquiring angular velocity in the steering process of the vehicle in real time; setting a prediction time interval, and determining the product of the prediction time interval and the angular velocity of any moment in the steering process of the vehicle as a predicted deflection angle of the vehicle at the moment; determining the predicted deflection angle of the vehicle at the moment as a follow-up control angle of the vehicle headlamps at the moment. According to the method, deflection angle changes during the steering of the vehicle are predicted to correspondingly compensate the deflection angle of the headlamps to realize dynamic adaptive follow-up regulation; the vehicle dynamically runs, an angular velocity value can be dynamically and instantly obtained, and the predicted angle can be regulated at any time, so that prediction errors are reduced to a great extent.
Description
Technical field [0001] The invention relates to the technical field of vehicle lamp control, in particular to a predictive follow-up control method for vehicle headlights. Background technique [0002] The headlight of the vehicle is set at the front of the whole vehicle, and it mainly plays the role of illumination and signal. The light emitted by the headlights for lighting can illuminate the road conditions in front of the vehicle body, so that the driver can drive safely in the dark or in poor light places. The headlights for lighting can be divided into halogen tungsten according to the light source. Lamps, xenon lamps, etc. [0003] During the driving of the vehicle, due to different road conditions and different driving conditions, the lighting requirements for the headlights are actually different, especially when the vehicle is turning, due to the requirements for safe driving of the vehicle, the lighting of the headlights The status requirements are different. However,...
