Abstract

An apparatus and method for illuminating a vehicle including a light source connected to an illuminatable component such as an interior or exterior vehicle door handle or steering wheel, and a control system including a plurality of sensors that monitor the vehicle and surroundings for predetermined conditions and selectively illuminate the component as a means of conveying information or warnings about the vehicle or its surroundings. Illumination may be enhanced by other auditory signals such as audio alarms or vibration. Predetermined conditions may include the proximity of a vehicle user, key fob activation or proximity, input from an entertainment system, activation of a pressure sensor, the presence of a person or object in proximity to the vehicle, or the vehicle'"'"'s ignition or gear state.

Claims

1. A vehicle lighting system comprising:

a passenger compartment;

a steering wheel having a rim operatively connected to a hub, said rim being selectively illuminatable at any location around its circumference, by at least one light source in response to a detection of an obstacle in proximity to a vehicle having the system;

a controller electrically connected to said at least one light source and configured to selectively cause said at least one light source to illuminate said rim at said location, wherein said location always directly corresponds to a relative position of the obstacle with respect to the vehicle; and

at least one sensor configured to monitor the proximity of said vehicle on all sides of said vehicle for the presence of said obstacle, and to transmit signals indicative of the presence of said obstacle;

the controller being configured to determine whether the transmitted signals are indicative of the presence of said obstacle and to cause the at least one light source to illuminate said rim at said location in proportional response to the signals, wherein at least one of the size and the length of an illuminated portion of said rim is substantially proportional to at least one of the size and the proximity of the obstacle;

wherein said controller automatically adjusts said location to thereby continuously display said relative position on said rim in response to a rotation of said steering wheel.

2. The lighting system of claim 1, wherein the entirety of said rim is constructed from a non-opaque material to allow said rim to be internally illuminated by said at least one light source.

3. The lighting system of claim 1, wherein at least one of the color and the intensity of the light emitted by said lighting source may be varied by the controller in response to the proximity of said obstacle.

4. The lighting system of claim 3, wherein said response includes at least one of a strobing, pulsing, a change in color, and a change in intensity.

5. The lighting system of claim 1, wherein said controller is further configured to selectively activate at least one audio or vibrational alarm in proportional response to said signals.
