An electric motorcycle includes a housing for housing an electric motor and/or a transmission. The housing is positioned at the center of the electric motorcycle in a front view. An internal cooling device and/or an electronic component and two cooling elements extend outward from opposite sides of the housing. Exterior cooling ribs are arranged on the cooling elements. The cooling ribs extend in the longitudinal direction of the electric motorcycle, such that the cooling elements and the cooling ribs are directly in contact with the air surrounding the electric motorcycle. The cooling device and/or the electronic component is, at least in portions, housed in and thermally connected to at least one of the cooling elements.

A high-voltage cable connection structure includes a first connector to which a plurality of first high-voltage cables, each connected to a corresponding one of a plurality of terminals of a high-voltage battery, are connected, and a connector receptacle provided in a high-voltage control unit disposed outside a vehicle passenger compartment. Inserting the first connector into and pulling out the first connector from the connector receptacle allows connection and disconnection between the plurality of first high-voltage cables and the high-voltage control unit.

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 method can be used for controlling for engine running. An input unit receives required power data. A controller executes one among a first control for running an engine, a second control for keeping on running the engine, and a third control for stopping the engine, according to the required power data, to drive the engine. The battery is discharged or charged under control of the controller.

An electrified vehicle thermal management system includes, among other things, a transmission, an inverter, and a terminal block disposed between the transmission and the inverter. The terminal block includes a conduit configured to deliver transmission fluid from the transmission to the inverter. An electrified vehicle thermal management method includes circulating a transmission fluid between a transmission, a terminal block, and an inverter, and using the transmission fluid to manage thermal energy within the inverter.

A drive apparatus includes a motor; a reduction gear connected to the motor; a differential connected to the reduction gear, for rotating an axle about a differential axis; a housing including a gear housing portion housing the reduction gear and the differential; and an oil housed in the gear housing portion. The differential includes a gear for rotating about the differential axis. An end portion of the gear is lower than the reduction gear, and is configured to soak in the oil. The housing includes an oil drain hole and an oil feed hole for joining an interior of the housing and a space outside of the housing, a first stopper member removably in the oil drain hole, and a second stopper member removably in the oil feed hole. Each of the oil drain hole and the oil feed hole is in a portion of the gear housing portion.

A system for controlling cooling of a power electronics (PE) part of an electric vehicle includes a driving load determiner configured to estimate a weight of the vehicle and to determine a driving load level based on the estimated weight, and a PE part temperature controller configured to change a cooling start reference temperature of the PE part depending on the determined driving load level.

A scalable tractive power system for vehicles (car, truck, bus, semi-trailer), integrated with all-wheel steering system which leverage synergies between plurality of differently designed electric traction-motors and all-wheel electric steering-motors is configured with plurality of sensors to virtually eliminate wheel-dragging and EPS, as part of virtually 100% dynamic efficiency. A fully automated electronic clutch-system attached to selected electric traction motors is configured to carry out above 90% traction efficiency by coupling to wheels selected electric traction-motors in their high efficiency range of operation, and de-coupling and replacing electric traction-motors with another electric traction-motors while the vehicle is changing speed or when the vehicle requires higher or lower tractive-power, from forward-motion start to top-rated speed of the vehicle. A holistic controller is configured with multi-objective optimization design (MOOD) procedures computing complex variable values and parameters, finding the required trade-off among design objectives, and improving the pertinence of solutions, while complying with NHTSA's ‘fail operational systems’ for steer-by-wire.

A transmission (G) for a motor vehicle includes a housing (GG), a gear set (RS) arranged within the housing (GG), an electric machine (EM), and a power electronics module (LE). The power electronics module (LE) includes a carrier element (S), a DC voltage terminal (DC), an inverter (INV), and an AC voltage terminal (AC). The housing (GG) includes, on an outer wall (GGA), a region (GGE) for accommodating the power electronics module (LE), which is closable with the carrier element (S) of the power electronics module (LE). The region (GGE) of the housing (GG) and an inner side (SI) of the carrier element (S) form a dry space (TR) for accommodating the inverter (INV), which is attached to the carrier element (S). The region (GGE) of the housing (GG) at least partially separates the gear set (RS) from the dry space (TR).

A block-like electric drive providing two single-wheel drives on one axle comprises two electric machines, each having a parallel rotor axis and a transmission on an end face. The single-wheel drives or the electric machines are arranged at least partially congruent with each other in a longitudinal vehicle direction for installation. A respective inverter serves to actuate each one of the two electric machines, the inverters being arranged next to each other at a highest point of the drive block in the installation position. The two electric machines are arranged one behind the other with regard to their housings. The drive block thus has two drives with separate transmission housings. Each drive can advantageously be equipped with a parking lock for blocking an output shaft. A locked state can thus be created in each drive combination.
