Automotive Lighting Testing and Requirements

2020-06-17
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.

Unsettled Topics Concerning Automated Driving Systems and the Transportation Ecosystem

2019-11-25
EPR2019005
Over the last 100 years, the automobile has become integrated in a fundamental way into the broader economy. A broad and deep ecosystem has emerged, and critical components of this ecosystem include insurance, after-market services, automobile retail sales, automobile lending, energy suppliers (e.g., gas stations), medical services, advertising, lawyers, banking, public planners, and law enforcement. These components – which together represent almost $2 trillion of the United State economy – are in equilibrium based on the current capabilities of automotive technology. However, the advent of autonomous vehicles (AVs) and technologies like electrification have the potential to significantly disrupt the automotive ecosystem. The critical cog governing the rate and pace of this shift is the management of the test and verification of AVs.

Optimization of vehicle side panel to improve crashworthiness.

2019-28-2573
The front of a car, though susceptible to the biggest impacts in terms of magnitude, has space and additional reinforcement to incorporate various safety measures. The rear has considerable amount of space to contain a proper crash box. The side of the car, though, doesn’t have this flexibility in design, the main limiting parameter being space. Any intrusion into the passenger cabin can result in serious injury or even death. The objective of this work is to improve the crashworthiness of a vehicle’s side so as to reduce intrusion into the passenger cabin. The work is focused on optimizing the door and B pillar. The optimized side panel is compared with the baseline model as per standard. ANSYS solver is used for the simulation. The optimized design applied to the door and B pillar will significantly improve crashworthiness of the vehicle side panel as a whole.

Passenger "Sleeper Bus" Structure, an Optimization Study using Finite Element Analysis

2019-11-21
2019-28-2537
Sleeper buses are increasingly used as connectivity between cities and remote areas with sleeping comfort for passengers. During the normal operation, the bus body is subjected to several loads, external loads from the road (i.e. crossing over a speed bump, breaking & cornering). Moreover, there is a substantial possibility that these loads may lead to a structural failure. Hence, it is necessary to determine stresses occurred in the bus body to ensure its integrity under these driving scenarios. During the accident, rollover/front/rear/side impact, energy absorbing capacity of bus body structure is crucial for safety of passengers. The objective of this study is to reduce weight of bus structure while maintaining cost & safety as constraint. 3D Model prepared in NX and finite element model created in hypermesh ,LS-dyna/optistruct used as solver and post processing done in hyperview. In this study, fully loaded bus with passengers as well as maximum language mass, considered.

PMSM motor drive for Electric Vehicle applications

2019-11-21
2019-28-2475
To control air pollution in urban areas and to reduce carbon print in the cities, nowadays EV’s are preferred over IC engine vehicles. Earlier Electric vehicles used DC motor and Induction motors. But Brushless Permanent Magnet motors are preferred over Induction motor for EV’s due to their High Torque density, high-power density and highly efficiency. Prevalent Electric vehicles today have Brushless DC motors. Compared to BLDC, PMSM motor have smoother control and negligible torque ripplesThus, PMSM motor is preferred over BLDC for Electric Vehicle, because of its sinusoidal back emf which results in smoother control, and results into smoother and more comfortable driving experience to users. Methodology Sensor based field-oriented control (FOC) is implemented in 48 V 5kW Interior PMSM motor. . To start the Synchronous motor initial position of the rotor magnetic field should be known.

Noise and vibration simulations method for electric hybrid tractor powertrain.

2019-11-21
2019-28-2469
Internal combustion (IC) engines have been serving as prime source of power in tractors, since late 19th Century. Over this period, there have been significant improvements in IC engine technology leading to increased power density, reduction in tailpipe emissions and refinement in powertrain noise of tractors. As the regulations governing tailpipe emissions continue to be more stringent, original equipment manufacturers also have initiated work on innovative approaches such as diesel-electric hybrid powertrains to ensure compliance with new norms. However, introduction of such technologies may impact customer’s auditory, vibratory and drivability perceptions. Absence of conventional IC engine noise, association of electric whistle and whine, torque changes with activation/de-activation of motors and transmission behavior under transient conditions may result in new NVH issues in hybrid electric vehicles.
