An active apparatus for modifying aerodynamic properties of a vehicle, encompassing: a frame; a movable portion movable relative to the frame along a motion path; a transceiver to emit a transceiver signal and has a specified transceiver position relative to the frame; an antenna to receive the transceiver signal and arranged on the movable portion, an antenna signal, induced by a predetermined transceiver signal, of the antenna exhibiting a predetermined functional dependence dependent on a position of the movable portion along the motion path and on the transceiver position; a signal transmitting unit to emit a unit signal that is associatable with the antenna and carries information regarding the antenna signal, the transceiver configured to receive the unit signal; and a signal evaluation unit, the signal evaluation unit configured to determine the position of the movable portion along the motion path on the basis of the unit signal, the functional dependence, and the transceiver position.

A thermal energy control apparatus for a hybrid vehicle is capable of efficiently managing thermal energy. The apparatus includes an integrated thermal management (ITM) unit that adjusts a coolant temperature by opening or closing a radiator valve and an active air flap (AAF) unit that adjusts an intake amount of ambient air by opening or closing a flap valve. A cooperative controller cooperatively operates the ITM and AFF units. The cooperative controller determines, based on a coolant temperature, whether a cooperative control mode is to be executed, adjusts an opening degree of the flap valve when the cooperative control mode is a cooperative control mode of the AFF unit, and adjusts an opening degree of the radiator valve when the cooperative control mode is a cooperative control mode of the ITM unit.

A genset includes an enclosure and a deflector assembly. The enclosure defines an at least partially enclosed space and a ventilation air opening that fluidly couples the enclosed space with an environment surrounding the enclosure. The deflector assembly includes a deflector disposed within the enclosed space and an angle driver. The angle driver is structured to adjust an angular position of the deflector relative to the ventilation air opening to minimize exported noise.

An apparatus for controlling an active air flap (AAF) of a vehicle may include a plurality of sensors configured to detect status information of the vehicle; an opening degree controller configured to control an opening degree of the AAF; and a processor configured to determine a target flow and a target opening degree of the AAF based on the status information, calculate an initial speed of a wake generated by a preceding vehicle based on vehicle information of the preceding vehicle, obtain a speed of the wake when the wake arrives the vehicle based on a speed of the vehicle, an inter-vehicle distance between the vehicle and the preceding vehicle, and the initial speed of the wake, correct the target opening degree based on the speed of the wake, and adjust the opening degree of the AAF corresponding to the corrected target opening degree.

A cooling system of a hybrid vehicle includes a radiator, an openable and closable first shutter, an openable and closable second shutter, and a control device. The radiator is placed forward of an internal combustion engine and a heat generation device configured to generate heat along with operation of the drive motor, and the radiator communicates with the heat generation device and the internal combustion engine such that a coolant circulates through the internal combustion engine and the heat generation device. The first shutter extends from a front end of an undercover so as to cross between the radiator, and the heat generation device and the internal combustion engine. The second shutter extends between a front end part of the undercover and a lower part of the radiator. The control device controls opening and closing of the first shutter and the second shutter.

An outdoor unit has a frame that carries a ground grooming or working implement, a traction drive, and a cooling fan, all of which comprises loads on a prime mover. A power management controller automatically reduces an operational speed of the traction drive when prime mover droop is present. The cooling fan cools two cooling fluids. The controller stores data representing variable fan speeds for cooling each cooling fluid in both normal and above normal temperature ranges and for use when prime mover droop is present. The controller uses the highest fan speed required for cooling the cooling fluids in the normal range unless the droop fan speed is lower in which case the lower droop fan speed is used but only to the extent that the lower droop fan speed is not lower than the highest fan speed required for cooling the cooling fluids in the above normal temperature range.

A cooling system for a motor vehicle, has a first cooling circuit arrangement with a first coolant cooler and a second coolant circuit arrangement with a second coolant cooler. A cooling air supply to the first coolant cooler can be varied by means of a first cover device, and a cooling air supply to the second coolant cooler can be varied by means of a second cover device. The first cover device and the second cover device can be moved by means of an interposed gear of a shared drive, whereby the gear is configured such that, when the drive is being operated for opening purposes, the second cover device is moved earlier and/or faster than the first cover device out of a closed position in the direction of an open position. This makes it possible to supply cooling air to meet an already existent cooling demand of the second coolant cooler, whereas such a cooling demand does not yet exist for the first coolant cooler, so that the latter can still remain covered—in terms of a flow of cooling air—by means of the associated (first) cover device. This can have a positive effect on the flow resistance for the cooling air and thus on the aerodynamics of the motor vehicle.
