Abstract With increasing concern over the environment and ever stringent emissions regulations, the electric vehicle has been investigated as an alternative form of transportation. However, the electric vehicle suffers from relatively short range and long charging times and consequently has not become an acceptable solution to the automotive consumer. The addition of an internal combustion engine to extend the range of the electric vehicle is one method of exploiting the high efficiency and lack of emissions of the electric vehicle while retaining the range and convenient refueling times of a conventional gasoline powered vehicle. The term that describes this type of vehicle is a hybrid electric vehicle. Many configurations of hybrid electric vehicles have been designed and implemented, read more

Abstract Modeling and control of a hybrid electric vehicle is presented in this paper. A four wheel drive parallel hybrid electric vehicle is built by assembling an auxiliary electrical machine and battery group. Some preliminary instrumentation such as accelerator pedal, brake, clutch pedal position sensors and gear ratio estimation are realized to split torque demand into the two power sources. The first power source is the internal combustion engine and the second one is the permanent magnet electric motor. A rule-based control strategy is developed by setting transition rules between the two power sources. The control strategy is implemented on a proof-of-concept vehicle and road tested. In order to satisfy smooth transient switching between the two power sources, and in order not read more

Abstract A simulation model for a hybrid electric vehicle is developed. Permanent magnet synchronous motor is considered for the drive part of the hybrid electric vehicle which comprises three energy sources: (i) a fuel cell, (ii) a battery bank, and (iii) a super capacitor. Rotor-oriented speed controller is designed, and also verified by simulation results, to achieve trajectory tracking requirements of the hybrid electric vehicle within the inverter voltage and current limits. In recent years, hybrid electric vehicles (HEVs) have received much attention as a replacement for high-emission gasoheldiesel engine in cars, buses, and trucks. The main purpose of the use of HEVs is to decrease the urban air contamination especially caused by black smoke, hydrocarbons, and nitrogen oxides of read more
