    摘要: Examples of the present disclosure relate to techniques for headlamp heater control. In examples, a headlight assembly comprises a heater, which is used to prevent or remove condensation/precipitation on a lens of the headlamp assembly. Given it may be difficult for an individual to know when to manually turn the headlamp heater on, an electronic control unit (ECU) may evaluate a set of rules to determine when to automatically enable or disable the headlamp heater. The rules may be associated with atmospheric conditions outside the vehicle, the state of the vehicle (e.g., whether windshield wipers are turned on, whether windshield defog is enabled, whether a mirror heater is turned on, etc.), and/or user input received by an ECU of the vehicle, among other examples.

    摘要: A lens for a vehicle headlamp, the lens comprising an inner surface and an outer surface. A cleaning arrangement is arranged to provide a cleaning fluid to the outer surface of the lens. An inlet is connectable to a cleaning fluid hose for providing cleaning fluid to the cleaning arrangement. The cleaning arrangement comprises: a channel and an array of outlets in fluid communication with the channel. The channel is attached to the lens and is adapted to transport the cleaning fluid from the inlet to the array of outlets which are located on the outer side of the lens on the same side as the outer surface for providing the cleaning fluid to the outer surface of the lens. The invention also relates to a headlamp arrangement and a vehicle.
