The subject of this paper is the thermal limitations of automotive headlamp bulb shields. Close proximity to high intensity halogen headlamp bulbs cause bulb shields to reach unacceptable temperatures....
Most of the Driving Assistance functions require sensors that are looking ahead of the vehicle. Among these sensors, cameras, already providing Lane Departure Warning and Night Vision, will play a maj....
Useful driver assistance system must provide drivers with information and warnings that adapt to driver conditions such as driver awareness level, attention level etc. We have developed a prototype re....
This paper describes a driver's side outside rearview mirror that combines a spherically convex blind zone mirror with a planar main viewing mirror in such a manner as to comply with FMVSS 111. It is ....
A main requirement for a driver assisting automated parking system is the identification and localisation of a free parking spot. A sensory system consisting of a reverse aid camera, a processing unit....
A new design for a glare reducing car mirror is presented. Several aspects of human perception like the different spectral sensitivity of the eye during day and at night and its response to color puri....
The purpose of this paper is to present an updated methodology for validating the visibility of objects in low-illumination digital photographs. A procedure is presented for creating prints from digit....
The size of an average instrument cluster is much larger than what is actually required to present information on vehicle conditions. There exists an opportunity to present all of that information on ....
This report consists of an investigation of human perceptions of narrow band width coloured light sources (Light Emitting Diode or LED) and wide band width coloured light sources (filtered incandescen....
One of the widely known secrets in automotive lighting is the problem of detecting low reflectance roadway obstacles. At speeds beyond 40 mph, most drivers cannot see dark-colored obstacles (such as d....
The Uniform Detection Characteristic (UDC) locus circumscribes a region in front of a vehicle at which the luminance requirement for detecting a roadway obstacle is met by the vehicle's headlamp syste....
The effects of image size on perceived distance have been of concern for convex rearview mirrors as well as camera-based rear vision systems. We suggest that the importance of image size is limited to....
Over the years, there have been different ways to reduce glare from mirrors for drivers - dimmable electrochromic mirrors being the latest option. These mirrors often have a limited lifespan when expo....
We have developed a new automotive instrument cluster consisting of a dial made of a glossy natural metal in order to enhance the high-quality appearance of the cluster. The glass covering the cluster....
Since the Adapted Frontlighting System (AFS) was commercialized in 2003, it has helped improve visibility on curves. This paper reports that: The driver’s eye-fixation points change for different area....
When it comes to innovations for lighting in the front of motor vehicles, mostly the road illuminating systems are mentioned. However, in addition to the progress in the “real beam tasks” with swiveli....
Recent studies [2, 3, 4] have shown that with increase of the blue spectral content in the peripheral part of a headlamp beam pattern the visibility during night is also increased, especially at low a....
The directional turn signal is a vital safety feature, and when properly used by the motor vehicle operator, helps prevent countless collisions every day. As important as this safety feature is, its b....
Halogen light sources for automotive forward lighting applications are designed for a nominal DC voltage and power, typically in the range of 13 volts and 55 to 65 watts. However some applications att....
This paper describes motor vehicle lamp assemblies employing a mask that controls the photometric output, or cosmetic appearance of the lamp. The mask is comprised of materials such as liquid crystal ....
