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.

Clutch temperature management in a slip control method and arrangement for a drivetrain including a continuously variable transmission is described herein. The drivetrain includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. The temperature data from the clutch is used to determine the usable torque. Accordingly, the clutch prevents the prime mover from stalling.

Provided is a work machine capable of notifying that maintenance is necessary due to continuation of clogging in a cooling device or decrease in cooling performance. A wheel loader 1 including a radiator 31 and an oil cooler 32 comprises a controller 5, 5A configured to determine a clogging continuation state of the radiator 31 or the oil cooler 32. The controller 5, 5A determines whether clogging is occurring in the radiator 31 or the oil cooler 32 based on outside air temperature AW and cooling water temperature CW or hydraulic oil temperature HW, determines whether the clogging continues based on a clogging occurrence ratio R1, R2 while an engine 30 is operating, and outputs a notification command signal for providing the alarm buzzer 61 and the user management system 62 with a command to notify that maintenance is necessary when it is determined that the clogging continues.

The disclosed technology includes devices, systems, and methods for a battery-integrated heat pump system. The disclosed technology can include a heat pump system having a battery, a compressor, and a variable speed drive in electrical communication with the battery and the compressor. The variable speed drive can be configured to control a speed of the compressor. The heat pump system can include a fan that can be configured to move air across a heat exchanger coil of the heat pump system and the battery can be located in an airflow path of the fan such that the fan can also move air across the battery to regulate a temperature of the battery.

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.

In a vehicle including a first MG serving as a driving source, a power transmission mechanism configured to transmit power of the first MG to a drive wheel, and an oil circulation mechanism for cooling the power transmission mechanism and the first MG, it is determined that oil is short when a temperature of the first MG is higher than a temperature of the oil and a difference between the temperature of the first MG and the temperature of the oil is greater than a prescribed value.

When temperature of a second power source of a vehicle becomes higher than a threshold value during a first mode in which three rotating elements of a differential gear can make differential movement and when four-wheel drive is needed, switching is performed to a second mode in which the three rotating elements are unified, and when four-wheel drive is not needed even when the temperature of the second power source becomes higher than the threshold value during the first mode, output of the second power source is restricted, while the first mode is maintained.

A fuel system for a machine may include a fuel tank configured to hold cryogenic fuel, a pressure sensor, and an electronic control module (ECM). The ECM may determine a change in pressure of the fuel between a first time and a second time, determine a predicted change in pressure of the fuel between the first time and the second time, and determine that the change in pressure and the predicted change in pressure is greater than a threshold. Based on the change in pressure and the predicted change in pressure being greater than the threshold, a notification may be displayed associated with an integrity of the fuel tank.

A leakage detector for fuel vapor treatment device is configured to diagnose a leakage of a fuel vapor in a vapor path based on an internal pressure change of the vapor path with the vapor path functioning as a closed space. The leakage detector performs the leakage diagnosis of the vapor path by correcting the effect of the pressure of the fuel vapor with regards to the internal pressure change. The leakage detector comprises a vaporization promoting device and is configured to determine whether the fuel vapor in the gas space of a fuel pump has reached a saturated state.

The disclosure relates to a transmission and all-terrain vehicle having the same. The transmission includes a casing body defining an air inlet and an air outlet; a casing cover mounted to the casing body, the casing cover and the casing body cooperatively defining a cavity in communication with the air inlet and the air outlet separately; and a transmission mechanism having at least a part provided in the cavity.
