Policymakers, consumers and manufacturers are all agreed – the auto industry needs to adopt electrification to address climate change and dwindling natural resources – yet we still see very few hybrid and electric vehicles on the road today. Given the will is there, why the lack of adoption? In reality the main reason is not the technology, but rather the cost of developing the technology in th...

Due to less pollution, silence and high efficiency electric vehicles are fascinating to the citizens widely. There are number of physical and electrical aspects are to be considered during vehicle modeling. When electric vehicle runs on the concrete surface rolling resistance resist the vehicle tire to move fast. On the other hand when the vertical angle of vehicle drive is increased or decreas...

The four-wheel-drive electric vehicle's traction chain is powered by four permanent-magnet synchronous motors (PMSM), a single three-phase, five-leg inverter (FLI). In order to achieve the behavior of mechanical differential and require parallel wheel-motors turn at identical or different speeds, using this structure, an independent control applied on each driving wheel. For particular there sh...

Individually-controlled electric motors provide opportunities for enhancing the handling characteristics and energy efficiency of fully electric vehicles. Online power loss minimisation schemes based on electric motor efficiency data may, however, be impractical for real-time implementation due to the heavy computational demand. In this paper, the optimal wheel torque distribution for minimal p...

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...

This paper presents an H ∞ torque-vectoring control formulation for a fully electric vehicle with four individually controlled electric motor drives. The design of the controller based on loop shaping and a state observer configuration is discussed, considering the effect of actuation dynamics. A gain scheduling of the controller parameters as a function of vehicle speed is implemented. The inc...
