This paper presents the traction motor sizing for optimal urban fuel economy in two mild and three strong hybridization propulsion on front-wheel-drive vehicles. The traction motor sizes, by means of motor rated torque and speed, are optimized for maximum urban fuel economy. The two mild hybrids are Belt-Integrated-Starter-Generator (BISG) and Crankshaft-Integrated-Starter-Generator (C-ISG) sys...

This paper presents the movement dynamic of the train and the relationship between the speed of wheel and train, as well as a discussion about the concept of wheel slip. There are two different operation regions designated as creep and wheelspin areas for wheel slip. Creep and wheelspin areas have stable and unstable characteristics, respectively. Wheels and rails are constructed from iron, and...

In electric vehicles that use in-wheel motors, the right and left traction forces become unbalanced if a motor malfunctions by motor lock or loss of traction, generating yaw moment. Control methods were designed to reduce this effect by stopping the motor output on the opposite side of the same axle. By using a prototype “Eliica” car, the maximum yaw rate and lateral acceleration were compared ...

Electric drive is widely used in automotive practice. Its basis an electric traction motor (TM), which, compared with internal combustion engine (ICE), has such advantages as high efficiency, overload capacity, a wide range of speed control, and the possibility torque direct transmission to wheels. The main requirements for are efficiency over entire load range, ease small weight dimensions, re...

The purpose of the work is import substitution traction electric drives as part project to create in Chuvash Republic a serial production family front loaders with hybrid drive.
 
 For most transport motors, operation high-torque motor mode not main operating mode, since vehicle acceleration carried out short time overcoming low-efficiency low-speed modes. A distinctive feature for ch...

the use of micro-controllers in actuators provides extended flexibility for on-line data acquisition and sophisticated control implementation. however, attempts to utilize the excellent features of induction motor that is deemed by its strength, robustness, high torque, and relatively low cost in actuators face a fundamental control design challenge. the purpose of this paper is to introduce th...

Additional energy source of hybrid electric buses comprises new control tasks. One of the main challenges of hybrid electric buses is the integrated control between traction motor and brakes, associated with which is the problem of switching traction motor and brakes. Existing control techniques only provide a result of frequent switch and jerky ride. In this paper, we propose a control strateg...

This article describes the design of a traction control system in an electric Formula Student vehicle. In many race applications the accelerator pedal is difficult to control for an in-experienced driver, especially in the case of electric vehicles, where a large torque is available from standstill. A 3-DOF driveline model is used in combination with a 7-DOF vehicle model and a non-linear tyre ...

This paper proposes a novel torque and speed control structure for low-cost induction motor variable-speed drives with a single dc-link current sensor. The controller is based on reconstruction of the active and instantaneous reactive power from the dc-link current without the use of a shaft sensor. An effective way of achieving tracking of set values of motor torque and flux is to base the est...

he Brachial plexus constitute afferent motor and efferent sensory nerves supplying the upper extremities. It is situated in a very vulnerable T anatomical position between the neck and shoulder. Injury to this plexus, which is often due to traction, results in various degrees of motor and sensory deficit to the involved upper limb. This results in loss of function and its catastrophic consequen...
