A method for the performance-enhancing driver assistance of a road vehicle driven by a driver and provided with at least two drive wheels driven by at least one electric motor connected to a corresponding vehicular battery pack; the method comprises the steps of defining a dynamic model of the road vehicle; determining a route of a track travelled by the road vehicle; calculating, as a function of the dynamic model of the road vehicle and of the route, a convenience index relative to the use of energy of the vehicular battery pack by the electric motor; subdividing the route (R) into a plurality of sectors assigning to each a relative value of the calculated convenience index; delivering electrical power to the drive wheels according to the value of the convenience index assigned to each sector of the route.

An electronic control module, particularly for a transmission, includes a first circuit board element and a sensor unit carrier fastened to the first circuit board element. The sensor unit carrier has a sensor unit receptacle configured to receive a sensor unit. The sensor unit has a sensor element fastened and electrically connected to a second circuit board element so as to detect at least one measured value. The sensor unit is fastened in the sensor unit receptacle. The second circuit board element has a flexible region that separates a first sub-region of the second circuit board element from a second sub-region of the second circuit board element. The first sub-region has a predetermined angle to the second sub-region. The sensor element is electrically connected to the first circuit board element by the second sub-region of the second circuit board element.

A drive device includes a motor having a motor shaft that rotates, a motor housing unit that houses the motor, a gear unit that transmits rotation of the motor shaft to an intermediate shaft, and an inverter housing unit that houses the inverter, wherein the inverter housing unit is disposed above the intermediate shaft, a lower wall portion of the inverter housing unit faces outside air, and the inverter housing unit has a vent that allows an inside of the inverter housing unit and an outside below the inverter housing unit to communication with each other.

The present invention relates to an electric power generating system for vehicles. The system includes at least one wind turbine positioned to capture incoming air which is coupled to a wind generator for converting into electric power. The system has solar panels installed on the exterior surface of the vehicle such as trailer of a semi-truck for absorbing solar energy and converting into electric power. The electric power produced by the wind generator and the solar panels is stored in a battery pack for providing electric power to the electric battery of the vehicle. An emergency generator provides electric power to the vehicle when the power of both the electric battery and the battery pack is insufficient. The system slows down the depletion of battery charge, thus enabling the vehicle to stay on the road for a longer duration and improves overall charging experiences for the electric vehicle.

A valve for a fluid system of a vehicle having a valve housing with valve housing openings, a valve body arranged so as to be rotatable about an axis of rotation, a valve seal, a valve drive, and a plurality of connecting pieces corresponding to the valve housing openings. The connecting pieces have a circular flow passage area in cross section at a free end of the respective connecting piece, and the valve housing openings, corresponding to the connecting pieces, each have a substantially rectangular cross section. The respective valve housing opening is larger than the flow passage area at the free end of the corresponding connecting piece, and the flow passage areas of the connecting pieces widen in a diffuser-like manner from the free end of the respective connecting piece to the respective corresponding valve housing opening and merge in a stepless manner into the respective valve housing opening.

A motor having a motor shaft rotatable about a motor axis; a power transmission having gears and connected to the motor shaft; a housing having a motor housing portion accommodating the motor and a gear accommodation portion accommodating the power transmission; a fluid contained in the housing; and a fluid channel through which the fluid flows, in which a reservoir storing the fluid above the motor axis is provided in the inside of the gear accommodation portion. The fluid channel includes an external supply channel for supplying the fluid from an outside of the motor to the motor, and an internal supply channel for supplying the fluid to a hollow portion of the motor shaft. The reservoir has a first supply port and a second supply port. The external supply channel is connected to a first supply port. The internal supply channel is connected to a second supply port.

An apparatus for electrically and mechanically coupling battery modules to an electric vehicle includes an interface plate and one or more battery trays. The interface plate includes an electrical output that electrically couples the interface plate to the vehicle. The interface plate also includes an electrical input that is electrically coupled to the electrical output. The battery tray is configured to receive a plurality of replaceable battery modules and is releasably mechanically coupled to the interface plate.

An under body may include a side sill inside front panel bent similar to the side sill inside panel to connect a front end portion of the side sill inside panel with a dash panel to be bonded to each other; a front side member connecting member connected with a bottom surface of the dash panel and a rear end portion of a front side member while being bonded to an inside surface of the side sill inside front panel; a side sill inside rear panel configured to connect a rear end portion of the side sill inside panel with a rear side member to be bonded to each other; and a rear side member connecting member configured to connect a bottom end portion of the side sill inside rear panel with a front inside surface of a rear side member to be bonded to each other.
