Self-dimming vehicle headlights

摘要

A system by which high beam lights on motor vehicles are automatically dimmed when a similarly equipped vehicle is approaching from an oncoming direction utilizes transmitted radio frequency (RF) signals between vehicles which operate at a preset range. Vehicles equipped with the system also comprise front, rear, and side vehicle sensors to differentiate RF signals transmitted from oncoming or trailing vehicles. A receiving antenna portion of the system picks up an RF signal, verifies there are no proximal side or trailing vehicles, and deactivates the high beam circuit for a preset period of time. All vehicles equipped with the system provide an RF signal having a digital identification code to prevent interference. The system is preferably introduced as a retrofit kit for installation upon existing vehicles; however, the system may also be incorporated on new vehicles.

主权项

1. A self-dimming vehicle headlight system, comprising:
an electronic control module adapted to be in electrical communication with a high beam light dimming portion of a wiring harness of a vehicle; an internal transceiver in electrical communication with said electronic control module; an antenna in electrical communication with said internal transceiver adapted to be removably mounted to said vehicle; a front sensor in electrical communication with said electronic control module adapted to be mounted to a front of said vehicle; at least one side sensor in electrical communication with said electronic control module adapted to be mounted to either side of said vehicle; and, a rear sensor in electrical communication with said electronic control module adapted to be mounted to a rear of said vehicle; wherein said internal transceiver continuously transmits a signal through said antenna; wherein said internal transceiver receives and transmits said signal as an RF signal over an approximate range of one-half mile; and, wherein a high beam headlight of a first vehicle equipped with said system is automatically dimmed when said internal transceiver receives a signal from a second vehicle equipped with said system and said rear and said at least one side sensor of said first vehicle do not detect a proximal vehicle.
