A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

The present invention relates to electric drivetrain kits for converting all-terrain vehicles into hybrid or electric vehicles. In exemplary embodiments, a conversion kit replaces an existing standard single motor and transmission drive system with a dual set-up including a motor for each rear wheel and a split transmission that houses two sets of gear reduction components in a single housing or an all-wheel configuration with two transmission sets (front and rear). Dual output shafts in each transmission set drive the wheels independently to provide the torque needed as required and demanded by each wheel.

A vehicle power station including a housing, a control circuit for controlling charging and discharging, a receptacle, a removable power module configured to be received in the receptacle, a vehicle electrical system electrically coupled to the power station, and a vehicle motor electrically coupled to the power station wherein the control circuit is configured to discharge power from the removable power module into the vehicle electrical system.

A vehicle comprising a framework in form of beam, wheel, drive and braking system, while the vehicle is partially loaded with the weigh of user and the user stands on roller skates and holds the vehicle on the beam so that the wheel is behind the user and contacts with its tire the road surface; and when the user activates the drive, the wheel starts rotating and, as a result of friction between the wheel's tire and the road surface, there arises a force making the vehicle with user move. Additionally, another technique for operation of the same vehicle is being offered, at which the vehicle on the move is positioned in the front of user.

A wheel assembly includes an attachment module, a motor module, a battery module, and a wheel. The wheel is rotatably coupled to the attachment module about a rotational axis of the wheel. The attachment module has a plurality of coupling elements, and the motor module and the battery module each releasably couple to one of the coupling elements. The wheel extends around the attachment, motor, and battery modules. The motor and battery modules are identically shaped in a direction along the rotational axis.

A control unit for a vehicle having an active steering system capable of changing a steering gear ratio between a steering angle of a steering wheel and a tire steering angle includes a steering turning assist controller and a left-right driving force controller. The steering turning assist controller controls the steering gear ratio so that a yaw rate generated by the vehicle becomes a target yaw rate to assist a turning of the vehicle. The left-right driving force controller controls, in the left and right electric drive wheels which each add a yaw moment to a vehicle body independently of a steering system and are able to be independently driven, driving forces of the electric drive wheels so that the yaw rate generated by the vehicle becomes the target yaw rate based on a roll of the vehicle.

A torque stick apparatus for driving a personal transporter across a transport surface by positioning the torque stick apparatus against a drive surface is described. The torque stick apparatus includes a tubular housing, throttle control, battery pack, motor coupled to a wheel, and motor controller. The motor controller is coupled to the motor, the battery pack, and the throttle control. The motor controller determines whether to select regenerative braking mode based at least in part on the position of the throttle control. The motor controller supplies power from the battery pack to the motor in accordance with the throttle control when regenerative braking mode is not selected. The motor controller provides power from the motor to the battery pack when regenerative braking is selected. The battery pack and the motor controller are contained within the housing.

An apparatus for controlling an electric motor in a motor-assisted, pedaled or hand-cranked vehicle includes a processor adapted to calculate a value for the net opposing force acting on the vehicle; a vehicle speed sensor, an accelerometer to measure a component of vehicle acceleration in a direction of travel of the vehicle, an air pressure sensor measuring air pressure in the direction of travel, a sensor that measures the power output of the electric motor, and a power assist processor that calculates an amount of power to be supplied by an electric motor according to measured values for speed, acceleration, air pressure, and power provided by a person riding the vehicle.

Provided herein is an auxiliary hybrid system (AHS) that may be configured to provide electrical propulsion to an e.g., internal combustion-powered vehicle through the use of a battery and electric motor. Alternatively, the AHS may be configured to increase range to electric vehicles through the use of an internal combustion-powered generator. In either embodiment, the AHS is added to a vehicle without altering the operation of the vehicles standard drivetrain, allowing the vehicle to operate conventionally when the AHS is not engaged. The AHS is compatible with a wide range of vehicles with a minimum of vehicle-specific parts.

An electrically driven hydrofoil for fastening to a board in order to lift the board out of the water during travel operation, comprises at least one drive module, which as an autonomous unit is fastened to a portion of the hydrofoil that remains submerged in the water during travel operation, an electric battery, and an electrically operated propulsion device supplied with power by the battery. It is thus possible to equip a conventional hydrofoil and a corresponding hydrofoil board with an electric drive, without the need for modifications to the board or to the hydrofoil. The battery can be arranged in the drive module so that there will be no need to provide external electrical connection between the propulsion device and the battery. The drive module may thus form an autonomous unit that may be attached to the hydrofoil as required, but otherwise is separate from the hydrofoil.
