Vehicle lighting methods and apparatus, in which an LED-based light source is configured to generate at least visible radiation associated with a vehicle. The light source is controlled such that the generated visible radiation has a variable color over a range of colors including at least three different perceivable colors. Examples of vehicles in which such methods and apparatus may be used include, but are not limited to, an automobile, airplane, boat, non-motorized vehicle, etc. The LED-based light source may be disposed inside the vehicle (e.g., dashboard, instrument panel) or outside the vehicle (e.g., brake lights, undercarriage lighting), and may be controlled to generate white light as one of the perceivable colors. A user interface may be employed to facilitate an adjustment of the variable color of the generated visible radiation. Additionally, information relating to at least one condition associated with the vehicle may be employed to control the LED-based light source such that the variable color of the generated visible radiation is based at least in part on the condition associated with the vehicle.

The present invention includes a number of embodiments for improving vehicle situational awareness at intersections. A first embodiment may comprise a lens fitted at the top of the windshield or outside the vehicle, for refracting the light to the driver, so the driver may more easily see signals, signage and other features of an intersection, as well as other traffic. A second embodiment of the invention is used as an aid to prompt the driver that a light has changed. In a third embodiment, the light change sensor may be combined with other vehicle status information. As the car comes to a stop, the route guidance system may determine if the vehicle is at or in the vicinity of an intersection. Depending on the route guidance database, the system may also know whether or not there are traffic lights at the intersection. Using the vehicle's on board forward-looking radar sensor, the system may then determine if it is first in line at the intersection. In a fourth embodiment the system may be part of a portable after-market routing device. In a fifth embodiment the system, either portable or fixed, may be used to detect changes in the intensity of the brake lights of the vehicle ahead.

The information available to a driver of a vehicle is greatly expanded using wireless communications (e.g., using Bluetooth wireless communication devices). In one embodiment, information regarding an adjacent vehicle such as a brake light, a turn light, speed, distance, direction, etc., is transmitted from one vehicle to a nearby or adjacent other vehicle. The received information is used in any appropriate manner, such as causing the receiving vehicle to change vehicle speed or brake, to turn to avoid a collision, etc. In a second embodiment, roadside wireless transceivers collect information regarding passing vehicles, and central database is compiled relating to a traffic conditions. The traffic condition information can be passed back to the passing vehicles for appropriate use, e.g., causing the driver to slow down, or even causing a navigation device in the receiving vehicle to manually prompt for or automatically recalculate a best route to an intended destination. In yet another embodiment, broadcast transmitters can be established at signs and other significant locations transmitting information to passing vehicles. The broadcast information may be as simple as indicating the existence of the sign, or depending upon the range of the particular wireless transmitter, the existence of a particular sign, bump in road, curve, etc., can be forewarned far in advance of when the driver will actually see the relevant object. Alternatively, the broadcast information may be quite detailed, e.g., containing a detailed itemization and directions to a large number of gas stations, restaurants, etc., reachable from a particular exit from a highway.

A system and method to avoid collisions on highways, and to minimize the fatalities, injury, and damage when a collision is unavoidable. The system includes sensors to detect other vehicles, and computing environments programmed to evaluate when a collision is imminent and to determine whether the collision is avoidable. If the collision is avoidable by a sequence of controlled accelerations and decelerations and steering, the system implements that sequence of actions automatically. If the collision is unavoidable, a different sequence is implemented to minimize the overall harm of the unavoidable collision. The system further includes indirect mitigation steps such as flashing the brake lights automatically. An optional post-collision strategy is implemented to prevent secondary collisions, particularly if the driver is incapacitated. Adjustment devices are provided to enable the driver to set the type and timing of automatic interventions.

Any presence of brake light emissions of another vehicle to the forward of a subject vehicle is sensed in a color camera and microprocessor system that detects (i) red light(s) illuminations in excess of other colors, that are any of (ii) appropriately sized, (iii) appropriately located, (iv) simultaneously occurring, (v) spaced apart in separation, (vi) substantially horizontal, and/or (vii) of approximately of equal intensity, as would be appropriate to a single brake light, or to a pair of brake lights, as the case may be. The brake lights of the subject vehicle are preferably applied either during (i) the persistence of any detection of the brake light(s) of any other vehicle(s) to the forward, or (ii) normal application of the subject vehicle's own brakes. The forward-sensed rearward-propagated brake light signal is preferably delayed in propagation, limiting any propagation of minor perturbations in traffic. Optional application of the vehicle's own brakes may be conditioned upon (i) proximity to and/or rate of closure with a forward emission source as is preferably determined by angles, and/or upon (ii) rate of closure, speed or deceleration G force of the subject vehicle. The brake light signal, whether simple or sophisticated in either its development and/or presentation, beneficially alerts drivers to the rear of impending or actual slowing, thus deterring rear end collisions and promoting fuel economy.

This disclosure introduces a system which generates a visual, audio, and/or tactile warning to a driver of a lead vehicle when a possible rear-end collision is detected, based on the approach of a second vehicle from a rear direction. The system may also generate a warning signal (such as quick blinking red brake light, or an array of multi-color lights) directed to the approaching vehicle when it is determined to be approaching at an unsafe speed. The system may include one or more of: approaching-vehicle-sensors mounted on the back end of the lead vehicle, a computer processing system, a set of warning lights, a set of speakers within the lead vehicle, and an antenna and transmitter/receiver for communicating with systems of other vehicles. This system may include a connection to the existing taillight system and other existing systems in the lead vehicle. Extended systems may include connections to and control of head support system, seat-belt systems and airbags system to provide additional safety to the occupants of the lead vehicle. The system may also record and store a few seconds of sensor data of the pre-crash and crash related scene when an impact occurs, and provide blind spot warnings.

The present invention relates to a taillight assembly that includes a light source for emitting light and a light source enclosure having a light transmissive portion for transmitting light from the light source to an illumination zone. A portion of the enclosure includes a material that is affixed to selected regions of the light transmissive portion. By electrically energizing the material the light transmitting properties of the material can be altered for performing different taillight functions. A drive circuit is electrically coupled to the material in each region for selectively energizing the material and thereby controlling the functional light output of each region. All taillight functions can be accomplished by activating the bands on the light transmissive portion, including running light, brake light, reverse light, parking light and turning signal.
