Lighting Emitting Diode (LED), a new generation semiconductor light source often referred to as Solid-State Lighting (SSL), has been broadly adopted in illumination, display, visualization, and other areas due to its higher efficacy and longer life. LEDs, first introduced for automotive interior applications such as indicators, expanded to exterior applications including center high mounted stop lamps and other automotive signal lighting devices. Today, LED technologies are being used for night vision, occupancy detection, and many other automotive application areas.

It has not been commonly known that automotive exterior lights are safety devices and must comply with governmental regulations. Since the 1930s, the SAE Lighting Standards Committee has been actively working with the automotive industry OEMs, lamp makers, tier-two suppliers, and human factor experts to develop automotive lighting standards. These standards have been widely used or referenced by the U.S. federal or state governments in establishing and enforcing the lighting regulations.

EPP foams are most commonly used in automotive applications for pedestrian protection and to meet low speed bumper regulatory requirements. In today’s automotive world the design of vehicles are predominantly driven by CAE. This makes it necessary to have validated material model for EPP foams in order to simulate and predict performance under various loading conditions. Since most of the automotive OEMs depend on local material suppliers for their global vehicle applications it is necessary to understand the variation in mechanical properties of the EPP foams and their effect on performance predictions. In this paper, EPP foams from three suppliers across global regions are characterized to study the inter-supplier variation in mechanical properties. In order to understand the effect of inter-supplier variation on vehicle performance, LSDYNA rate dependent material model is developed and validated for low speed and pedestrian protection load cases.

Vehicle front panel is an interior part which have a major impact on the consumers’ experience of the vehicles. To keep a good appearance during long time aging period, most of the front panel is designed as a rough surface. Some types of surface defects on the rough surface can only be observed under the exposure of certain angled sun light. This brings great difficulties in finding surface defects on the production line. This paper introduces a novel polarized laser light based surface quality inspection method for the rough surfaces on the vehicle front panel. By using the novel surface quality inspection system, the surface defects can be detected real-timely even without the exposure under certain angled sun light. The optical fundamentals, theory derivation, experiment setup and testing result are shown in detail in this paper.

Modern automotive cockpit design trends have increased the number of displays and the locations and manner in how they are packaged. One theme in particular is the packaging of the displays in novel locations that may be marginal in terms of dynamic stability during road load vibrations. Examples of this include mirror or deployable displays that adjust their position in the vehicle. The image of the display may be partially or fully blurred during vibration events which can produce a poor HMI experience. This paper will present the results of a HMI study that that evaluated the readability of different sizes and contrast ratios of TFT color display graphics via jury evaluation during varying vibration acceleration and frequency levels in a controlled lab environment. The result of this study was identification of minimum natural frequencies and maximum acceleration levels for the display mounting structure as a function of display graphics size and contrast ratios.

Power steering pump is vital component of hydraulic power steering system. Failure of steering pump can lead to loss of power assistance. Prediction of hub load on pump shaft is an important design input for pump manufacturer. Higher hub loads than design load of pump bearing can lead to seizure of pump. Pump manufacturer has safe limits for hub load. Simulations can assist for optimization of belt layout and placement of accessories to reduce the hub load. Lower hub load can have direct effect on improvement of pump durability. This paper deals with dynamic simulation of belt drive system in MSC.ADAMS as well as vehicle level measurement of hub load on power steering pump. Hub load is measured with two different belt layout as well as in different maneuver related to cranking and high speed conditions at which the worst load cases are seen.

The vehicle performances are studied through the ride comfort and handling stability commonly. While the lateral performance should be mainly considered for the centre axle trailer combination, such as the maximum stable side-inclination, the anti-rolling stability, the lateral stability and so on. Based on the finite element method, a rigid-flexible coupling model for the truck combination was built and analyzed in the multi-body environment (ADAMS), in which the key components of the chassis and cab suspension were treated as flexible bodies. According to the auto standards and regulations, the lateral stability of the centre axle trailer was evaluated through several simulation analyses. The variables' effects on the lateral stability were studied by design of experiment. Furthermore, in order to improve the lateral stability of the trailer combination, the optimal design was obtained by the co-simulation of the ADAMS/Car, iSIGHT and Matlab.

To solve the problem of serious roller wear and improve the smoothness of the sliding door motion process, the rigid-flexible coupling multi-body model of the vehicle sliding door was built in ADAMS. Force boundary conditions of the model were determined to meet the speed requirement of monitoring point and time requirement of opening-closing process according to the bench test specification. The results of dynamic simulation agreed well with that of test so the practicability and credibility of the model was verified. In the optimization of the ride comfort of the sliding door, the shape parameters of the middle guide and the position of arm-shafts were selected as design variables while the impact load of rollers, the curvature of the trajectory and angular acceleration of the sliding door centroid were taken as optimization objectives.

More than half all pedestrian fatalities occur at night. To address this problem, in the 1950s through 1970s Blackwell conducted considerable research that showed that a way to account for the limitations related to drivers’ expectancies at night would be to limit a driver’s time to view the forward roadway. The reduced information during the limited exposure time became a surrogate for the limited information available to on-road drivers at night. With the release of the SHRP-2 naturalistic database, we are able to see how drivers responded to in-road obstacles at night such as animals, bicyclists, pedestrians, and tree limbs. Using the naturalistic response data as a baseline, safe closed road recognition methodology was developed. The closed road study built upon the early nighttime recognition work by Blackwell, the observers were allowed to view the forward roadway for 1 or ¼ second.
