Neural World Models for Computer Vision
… in complex environments like in autonomous driving. A human driver, or a self-driving system, perceives their surroundings with their eyes or their cameras. They infer an internal representation of the world which should: (i) have spatial memory (e.g. occlusions), (ii) fill partially …

Experimental Investigation on Different After-treatment Technologies for the Control of Pollutant Emissions from Automotive Diesel Engines.
… to be significantly high, especially during the urban driving; spontaneous release of stored NOx (without periodic rich regeneration such as for LNTs) was observed at high exhaust temperatures typical of extra-urban driving, highlighting the potential for a combined application with a downstream …

Hydrogen : what fuel cell vehicles and advanced nuclear reactors have in common
… efficiency advantage over hybrid vehicles in urban driving cycle. Therefore, there is a strong justification for federal support for hybrid vehicles that will achieve similar results, quicker. The second issue focuses on another important technology and policy question related to large scale …

Vehicle fuel economy benefit and aftertreatment requirement of an HCCI-SI engine system
… the benefit of implementing HCCI over driving cycle: * Power-to-weight ratio * Operation range of HCCI * Conditions of the driving cycle * Application of constraints that cause "un-natural" mode transitions * Application of transition penalties * Available after-treatment performance * …

A general, context-aware pedestrian trajectory prediction model
Autonomous driving on highways and freeways, as a feature, is already available in quite a few high-end commercial vehicles being sold today. Autonomous driving in urban environments, on the other hand, is still an active area of academic and industrial research [6], because of its relatively …

Performance Evaluation of a Cascaded H-Bridge Multi Level Inverter Fed BLDC Motor Drive in an Electric Vehicle
… system on a standard drive cycle, New York urban driving cycle. This highly transient driving cycle is particularly used because it provides rapidly changing acceleration and deceleration curves. Furthermore, the evaluation of the system under fault conditions is also done. It is …

Hybrid internal combustion engine : driving a vehicle using air compressed in braking
… while driven through 1373 seconds of typical urban driving (CVS cycle) were used, combined with a model to estimate engine friction, to carry out an available energy analysis of the hybrid engine. An air processing efficiency was incorporated into the analysis to determine how irreversible the …

Synthesizing Vehicle Cornering Modes for Energy Consumption Analysis
… full route consumption modeling. Two routes, an urban and highway, are modeled and driven to evaluate the accuracy of the full simulation model when compared with on-road data. The results show that corners can largely be ignored during energy consumption analysis for highways. The cornering …

Mesoscopic Fuel Consumption and Emission Modeling
… estimate vehicle emissions based on typical urban driving cycles. Most of these models offer simplified mathematical expressions to compute fuel consumption and emission rates based on average link speeds while ignoring transient changes in a vehicle's speed and acceleration level as it …

On generating driving trajectories in urban traffic to achieve higher fuel efficiency
… the purpose of generating optimal policies for driving a vehicle with information about upcoming traffic signals has been developed. The toolkit can be used to investigate how to generate the optimal velocity profile with upcoming traffic signals based on a model of second-by- second fuel …
