![]() This study attempts to estimate annual vehicle kilometers traveled (AVKT) per privately-owned passenger vehicle and their daily distance patterns by vehicle class and geographic region. Given the explosive growth of the passenger vehicle market and energy demands in China, research on vehicle-use intensity and driver-travel patterns is critical for better assessing travel demand and its implications for alternative fuel vehicles, energy security, and environmental policies. The following NTHV information is presented: the results of the trade-off studies are summarized the overall vehicle design the selection of the design concept and the base vehicle (the Chevrolet Citation), the battery pack configuration, structural modifications, occupant protection, vehicle dynamics, and aerodynamics the powertrain design, including the transmission, coupling devices, engine, more » motor, accessory drive, and powertrain integration the motor controller the battery type, duty cycle, charger, and thermal requirements the control system (electronics) the identification of requirements, software algorithm requirements, processor selection and system design, sensor and actuator characteristics, displays, diagnostics, and other topics environmental system including heating, air conditioning, and compressor drive the specifications, weight breakdown, and energy consumption measures advanced technology components, and the data sources and assumptions used. The NTHV uses a modified GM Citation body, a VW Rabbit turbocharged diesel engine, a 24KW compound dc electric motor, a modified GM automatic transmission, and an on-board computer for transmission control. The derivation of and actual preliminary design of the Near Term Hybrid Vehicle (NTHV) are presented. more » From this study it is concluded that hybrid vehicles are best suited for short range driving the life cycle cost of the preliminary design near term HV is 25% higher than that for a ICE vehicle the availability of essential materials such as battery leads needs investigation and further evaluation of the effects of acute petroleum shortages as well as increased fuel prices and of the desirability of various sizes of HV's is required. The reliability and safety, life cycle costs, and computerized simulation of vehicle performance are discussed. Using a modified General Motors X-body car (Citation) as the base vehicle, the preliminary design of the vehicle, the power train, including internal combustion engine, batteries, and transmission, and the electronic control system are described. ![]() After analyzing automobile usage in terms of trip lengths and purposes, the petroleum savings that could result from using hybrid versus conventional passenger vehicles were estimated. ![]() = ,Īctivities in Phase I of a program to develop a preliminary design of a hybrid (electric and internal combustion engine powered) vehicle are summarized. ![]()
