Embodiments of the present disclosure disclose a method and a system for controlling a motion of an electric vehicle (EV). The method includes determining a velocity profile moving the EV from an initial velocity over a period of time by minimizing the energy dissipation according to an energy-loss function. The energy-loss function maps values of acceleration and velocity of the EV to energy dissipation of the EV resulting from controlling one or multiple electric motors of the EV to move the EV at corresponding acceleration and velocity values. The velocity profile is a function of time. The method further includes controlling the one or multiple electric motors of the EV to generate a torque for moving the EV according to the velocity profile.

Techniques are disclosed for systems and methods to provide visually correlated radar imagery for mobile structures. A visually correlated radar imagery system includes a radar system, an imaging device, and a logic device configured to communicate with the radar system and imaging device. The radar system is adapted to be mounted to a mobile structure, and the imaging device may include an imager position and/or orientation sensor (IPOS). The logic device is configured to determine a horizontal field of view (FOV) of image data captured by the imaging device and to render radar data that is visually or spatially correlated to the image data based, at least in part, on the determined horizontal FOV. Subsequent user input and/or the sonar data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

A self-powered towable vehicle has an energy interconnection and distribution unit configured for electrical communication with a power source and an onboard computer of a primary vehicle. A wheel member of the self-powered towable vehicle is selectively movable between an unpowered mode and a powered mode. In the unpowered mode, the wheel member is free rotating. In the powered mode, the wheel member is driven. The energy interconnection and distribution unit is also configured to coordinate movement between the primary vehicle and the self-powered towable vehicle while the primary vehicle is moving. The self-powered towable vehicle is configured to move at a same speed as the primary vehicle when the wheel member of the self-powered towable vehicle is in the powered mode.

A system includes a converter for powering a synchronous electric machine to which it is connected by cables, an insulating device and a mechanism for short-circuiting phases of the machine. The system includes primary detectors for detecting an overcurrent in the converter and a securing device able to open the insulating device when receiving a primary detection signal emitted by the primary detector. The system also includes secondary detectors able to detect a short-circuit downstream from the insulating device and to emit a secondary detection signal toward the securing device, the latter actuating the closing of the mechanism for short-circuiting as long as they have already received a primary detection signal having led to the opening of the insulating device.

A tethered charging and recharging (TCR) drone assembly system is provided. The TCR drone assembly system may be a nurse vehicle-based, a master/slave vehicle-based, a stationary structure and/or free standing TCR drone assembly system. The TCR drone assembly system is especially suitable for use on moving vehicles, for example, a self-propelled conventional type vehicle operated by an operator and/or autonomous or slave autonomous vehicle with no operator on board. The TRC drone assembly system may quickly couple and may deliver energy charges, recharges or other types of power propellants to vehicles while the vehicles are stationary or in motion. The assemblies are especially suitable for providing power to vehicles when only limited downtime of the vehicles is desired. The assemblies are suitable for use in, for example, the agricultural, construction, defense or other industries.
