Abstract (en)

[origin: GB2598923A] A control system 1106 and method of controlling a variable tint (VT) glazing system 1110 of a vehicle that is configured to: receive a frequency band signal indicative of a radio reception frequency 1102 of a radio receiver of the vehicle (e.g. in-vehicle radio for listening to AM/FM radio broadcasts); compare the radio reception frequency with an operating frequency 1104 of the VT glazing system to determine a frequency shift 1108 for the operating frequency in dependence on the comparison; and output a frequency shift signal 1108 indicative of the determined frequency shift to control the operating frequency of the VT glazing system 1110. This can avoid interference between the operating frequency and the radio reception frequency and reduce unwanted noise in audio output. The system may also receive the frequency band signal in dependence on receipt of user identification data that indicates a particular user is accessing the vehicle.
