AI Technical Summary
Adjusting the dimming angle corresponding to each dimming gear of the headlight is complicated, and the rectification period is long and the cost is high.
A headlight dimming control device is provided, including a control module and a dimming motor. By receiving dimming instructions, the target pulse width modulation signal corresponding to the target dimming gear is found according to the mapping relationship between the dimming gear and the pulse width modulation signal, and the dimming motor is controlled to adjust the illumination angle based on the signal.
There is no need to adjust the hardware circuit, just adjust the pulse width modulation signal corresponding to each dimming gear, which can be adjusted at any time, with a short rectification period, low cost and simple operation.
