The invention provides a headlamp dimming control device, method and system and a vehicle. The headlamp dimming control device comprises a control module and a dimming motor. The control module is used for receiving a dimming instruction, and the dimming instruction is used for indicating the irradiation angle of the headlamp to be adjusted to a target angle corresponding to a target dimming gear; in response to the dimming instruction, searching a target pulse width modulation signal corresponding to the target dimming gear according to a mapping relation between the dimming gear and the pulse width modulation signal; and based on the target pulse width modulation signal, a dimming motor is controlled to adjust the illumination angle of the headlamp to the target angle. The problem that the operation of adjusting the dimming angle corresponding to each dimming gear of the headlamp is complex can be solved.
