Various disclosed embodiments include illustrative systems for performing hill stall/start assist functions. An illustrative drive unit controller receives a zero-speed command and electric motor information, generates a torque command based on the received zero-speed command and the electric motor information, and instructs a drive unit inverter for an electric motor in response to the generated torque command.

A magnitude of a road surface slope along which a vehicle travels is detected, when the magnitude of the road surface slope increases, a basic braking force set in advance is corrected to be decreased based on the magnitude of the road surface slope, or a basic driving force set in advance is corrected to be increased based on the magnitude of the road surface slope, when the magnitude of the road surface slope decreases, a basic braking force is corrected to be increased based on the magnitude of the road surface slope or a basic driving force is corrected to be decreased based on the magnitude of the road surface slope, and the corrected braking force or driving force is generated.

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.

A system for providing a movement assistance to an electric cycle is provided. The system includes circuitry communicatively coupled to an electronically-actuated driving mechanism and a sensor system of the electric cycle. The circuitry receives sensor information associated with the electric cycle through the sensor system and determines an inclination of the electric cycle with respect to an inclination-reference based on the received sensor information. The circuitry further determines occupancy information associated with a seat of the electric cycle based on the received sensor information. Based on the determined inclination and the determined occupancy information, the circuitry controls the electronically-actuated driving mechanism to drive at least one wheel of the electric cycle.

A method for holding a two-track motor vehicle is provided, wherein the motor vehicle has at least one electric drive machine and wherein each of four wheels of the motor vehicle can be held via a service brake. In an initial situation when the motor vehicle is at a standstill, the motor vehicle is held by virtue of a motor torque of the electric drive machine being applied to at least two wheels of the motor vehicle. In a manner dependent on a situation and/or gradient, the motor torque that holds the at least two wheels of the motor vehicle is reduced at one wheel. After the motor torque at the one wheel is reduced, the service brake at the wheel is activated. After the service brake at the one wheel is activated, the motor torque at a further wheel of the vehicle is reduced. After the motor torque at the further wheel of the vehicle is reduced, the service brake at the further wheel is activated.
