This paper presents the modelling and real time implementation of PEM (polymer electrolyte membrane) fuel cell flow control. Flow control presents a critical performance requirement to achieving dynamic power responses for electric vehicle motor dema...
Concerns regarding global climate change have caused the transportation sector to look for alternatives to petroleum as a fuel for vehicles of all types. Hybrid electric vehicles (HEVs) have been recognized as being particularly efficient for urban t...
In recent years, development of environment measure cars is an important theme of the earth environment protection and energy saving. Various kinds of hybrid electric vehicles increase the production rapidly. However, the vehicle price is one of the...
This paper proposes a nonlinear observer for Body Slip Angle (β) estimation, in which a nonlinear tire model is adopted for the observer design. A newly developed method to identify parameters of road surface friction coefficient (μ) is introduced in...
The electrically propelled vehicle makes use of various technologies and is thus faced with diverse standardization and regulation cultures. The relevant standardization landscape is a complex one, particularly if new energy vectors such as hydrogen...
The relative fuel consumption reduction strengths of multiple passenger car powertrains are investigated. These include [A] conventional compression ignition (CI) direct injection (DI) turbocharged (TC) diesel (D) [CI-DI-TC-D]; [B] Atkinson cycle cha...
Average losses of the electric drive throughout a driving cycle are an important issue for hybrid electric vehicles. Permanent magnet synchronous electric motors (PMSM) are the most efficient electric drives under load conditions. However, they suffe...
Hino Motors, Ltd., developed the new light-duty hybrid truck whose traction motor, inverter, and traction battery were completely redesigned for maximizing output and efficiency. It also succeeds in balancing low fuel economy and low exhaust emission...
Motor control algorithm for a dual power split system is proposed for hybrid electric vehicles (HEV). The dual mode power split system consists of an electric variator, MG1 and MG2, and three planetary gear sets. In order to develop the control algor...
Regenerative Braking Systems (RBS) provide an efficient method to assist hybrid electric buses achieve better fuel economy while lowering exhaust emissions. This paper describes the design and testing of three regenerative braking systems, one of whi...
