In this paper, a novel robust rolling stability control (RSC) based on electronic stability program (ESP) for electric vehicle (EV) is proposed. Since EVs are driven by electric motors, they have the following four remarkable advantages: (1) motor torque generation is quick and accurate; (2) motor torque can be estimated precisely; (3) a motor can be attached to each wheel; and (4) motor can ou...

Several rodent species that are diurnal in the field become nocturnal in the lab. It has been suggested that the use of running-wheels in the lab might contribute to this timing switch. This proposition is based on studies that indicate feed-back of vigorous wheel-running on the period and phase of circadian clocks that time daily activity rhythms. Tuco-tucos (Ctenomys aff. knighti) are subterr...

This paper proposes model based current sensor and position sensor fault detection and isolation algorithm for driving motor of In-wheel independent drive electric vehicle. From low level perspective, fault diagnosis conducted and analyzed to enhance robustness and stability. Composing state equation of interior permanent magnet synchronous motor (IPMSM), current sensor fault and position senso...

Rats were required to press a bar to activate a motor-driven wheel that forced them to run and subsequently to drink to turn off the wheel. Barpressing and lickilng increased, showing the onset and offset of running to be positively and negatively reinforcing, respectively. The experimental control of the offset of running, in contrast to the traditional control for onset only, served to demons...

In the next years is expected an important rise in sales of electrical scooters in the entire world but especially in China. In order to address this challenge the electric scooter industry has to be more competitive in the transportation market and therefore important improvements, in terms of energy density and costs, have to be done in the electric storage system and in the electric propulsi...

Inflatable wheels are a promising concept for longrange exploration of Mars as well as extremely rugged terrestrial terrains. This paper describes experimental studies that characterize the mobility of a single robotic inflatable wheel in terms of its ability to negotiate Mars-like cohesion-less soils, climb large discrete obstacles and endure the wear and tear caused by driving over kilometers...

In this paper, a method for reducing unspring mass as well as improving safety and ride properties of vehicles driven by in-wheel motors will be provided. To begin with, the advantages of vehicles armed with in-wheel motors will be described, after which some drawbacks of this idea will be studied. Then, to getting a better analysis, quarter car model will be studied in frequency domain. Gain o...
