This paper describes slope traversability analysis for a planetary exploration rover based on a terramechanics approach. In this research, the slope traversability is defined as consisting both of slope climbing and traversing (crossing) capabilities. The authors have been investigated traction mechanics between a wheel of a rover and loose soil. Applying our advantages in the wheel-soil intera...

The in-wheel electric vehicle is expected to be a popular next-generation vehicle because an in-wheel system can simplify the powertrain and improve driving performance. In addition, it also has an advantage in that it maximizes driving efficiency through independent torque control considering the motor efficiency. However, there is an instability problem if only the driving torque is controlle...

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...

Exercise has been recommended to improve motor function in Parkinson patients, but its value in altering progression of disease is unknown. In this study, we examined the neuroprotective effects of running wheel exercise in mice. In adult wild-type mice, one week of running wheel activity led to significantly increased DJ-1 protein concentrations in muscle and plasma. In DJ-1 knockout mice, run...

High power and miniaturization of motors in an in-wheel drive system, which is installed inside the wheels of a vehicle, are required for directly driving the wheels. In addition, an efficient cooling system is required to ensure high driving performance and durability. This study experimentally evaluated the heat dissipation performance of a 35-kW-class large-capacity in-wheel motor equipped w...

Anti-slip control, as a fundamental technique of vehicle stability prevents loss control vehicles, especially under extreme driving conditions. However, current methods fail to suppress slippage when steering. Therefore, new anti-slip approach for four-wheel independent-drive electric vehicles (EVs) based on the energy method is proposed. This makes full use distribution motor between body and ...

For the motion of distributed drive electric vehicles, this paper deigns a novel control strategy based on model predictive control, which can longitudinal and lateral simultaneously. Different with traditional strategies containing one vehicle controller four motor controllers, treats its in-wheel motors as object uses only to realize so that costs are reduced handling performance is improved....

This paper presents some techniques for driving novel 5 phase dual winding PMSM (Permanent Magnet Synchronous Motor) the in-wheel motor. The motor realizes change over characteristics that can expand area from high-torque mode to high-speed due construction. However, structure makes a high-current ripple high coupling between windings. proposes control methods reduce current ripple, including i...
