BACKGROUND In Spain, a federal road safety law went into effect in the fall of 1992 extending to urban areas the unrestricted use of safety helmets by all two wheel motor vehicle occupants. OBJECTIVES To assess the effect of the law in reducing fatal motorcycle crash injuries; to estimate the number of lives saved; and to determine changes in the distribution of severity and anatomical locati...

Typical rovers with wheels equipped with conventional grousers are prone to getting stuck in unconsolidated sandy dune inclines as the wheels tend to sink into the sand. This phenomenon is caused by the motion of the grouser through the sand during the latter half of the rotation, in which the grouser pushes the sand from underneath the wheel upwards and towards the backside of the wheel. This ...

In view of the high difficulty in coupling various electric vehicle parameters, intractable parameter estimation, and unreasonable distribution driving torque, four-wheel hub motor is applied to drive vehicles, which can instantly obtain torque speed achieve precise control each wheel. According longitudinal dynamics model, a progressive RLS (PRLS) algorithm for real-time estimation mass road g...

Hybrid electric vehicle technology (HEVT) is emerging as a reliable alternative to reduce the constraints of battery-only driven pure vehicles (EVs). HVET utilizes an motor well internal combustion engine for its operation. These components would work on battery power and fossil fuels, respectively, source energy mobility. The delivered either from or fuel both sources based user requirements, ...

To improve the comprehensive performance of distributed wheel-side four-wheel-drive electric bus, problem optimal distribution driving torque four motors is studied. Aiming at poor economy and failure switching control due to consideration both straight steering conditions, this paper proposes a fuzzy yaw moment strategy based on golden section search algorithm. Under full working according eff...

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 focuses on the design of power management strategy for four-wheel independent drive electric vehicles (4WID EVs). Since the efficiency of the motor and inverter is different under different driving conditions, genetic algorithm based optimal energy management strategy is proposed to maximize the efficiency of motor drive systems. Not only the efficiency of motor, but also the efficie...

This paper presents the traction motor evaluation method depending on the electric transmission energy transfer characteristics and different source of supply, including motor manufactures, diesel turbine manufacturers, wheel side reducer manufacturers and electric drive system integrated manufacturers. 9 evaluations are proposed in 3 levels from the motor body and control performance, electric...
