High Performance Hybrid Vehicle Concept—Preliminary Study and Vehicle Packaging

Optimizing Vehicle Occupant Packaging

Occupant packaging practice relies on statistical models codified in SAE practices, such as the SAE J941 eyellipse, and virtual human figure models representing individual occupants. The current packaging approach provides good solutions when the problem is relatively unconstrained, but achieving good results when many constraints are active, such as restricted headroom and sightlines, requires...

High performance liquid crystals for vehicle displays

We report three liquid crystal (LC) mixtures with a wide nematic range (−40°C to ~100°C), small visco-elastic coefficient and low activation energy for vehicular displays. Physical properties at different temperatures were characterized. These LCs greatly improve the performance of different display devices in a car: 1) for head-up projection using liquid-crystal-onsilicon with an average gray-...

Performance Evaluation of an In-Wheel Motor Cooling System in an Electric Vehicle/Hybrid Electric Vehicle

High power and miniaturization of motors in an in-wheel drive system, which is installed inside the wheels of a vehicle, are required for directly driving the wheels. In addition, an efficient cooling system is required to ensure high driving performance and durability. This study experimentally evaluated the heat dissipation performance of a 35-kW-class large-capacity in-wheel motor equipped w...

Cost and Effectiveness Study of Hybrid Electric Vehicle Technologies Based on China Data

A Comprehensive Vehicle NVH Performance Correlation Study

One of main NVH (Noise, Vibration and Harshness) deliverables for Chrysler Development System (CDS) is a fully correlated finite element model to be used for the referencing and the target setting process for the future program. To satisfy CDS requirements, a comprehensive feasibility study using the finite element modeling techniques along with the experimental methods to validate the CAE (Com...
