A cooling system for an electric drive device of a vehicle. The electric drive device includes a housing, a motor accommodated in a first space in the housing and a reducer accommodated in a second space in the housing. The cooling system includes a cooling pump, having a first suction port and a second suction port connected to the first space and the second space respectively. The cooling pump is operatively configured to alternatively suck in cooling liquid from the first suction port or the second suction port; and a cooler connected to an outlet of the cooling pump to receive the cooling liquid sucked in from the first suction port or the second suction port.

Powered wheel assemblies and methods of manufacturing and operating such assemblies are provided.

In order to improve a device for pulling a trailer and/or retaining a load carrying unit that is mountable at the rear end of a motor vehicle body and which comprises a supporting arm that is connected by a first end region to the motor vehicle body and is provided at a second end region with an element for attaching the trailer and/or for fixing the load carrying unit and furthermore which comprises sensors for capturing reversible deformations of the supporting arm caused by loads on the supporting arm in such a manner as to provided a device with which an allocation of captured elongations to individual applications of force is possible in as simple a way as possible, it is proposed that strain sensors which are affected by reversible deformations thereof be assigned to a supporting arm section of the supporting arm, and that, for capturing at least one selected bending strain, at least one strain sensor be arranged on one side and at least one strain sensor on an opposite side of a surface region of a neutral reference surface assigned to the selected bending load and that each of the strain sensors be arranged at a distance from this surface region.

Powered wheel assemblies and methods of manufacturing and operating such assemblies are provided.

A wheel fastener alarm is provided with a fastener body, a cap covering the fastener body, a sensor array disposed within the fastener body, and a cover disposed over an opening in the fastener body and a hole in the cap.

A power control system may include at least one of batteries, a motor, and a data logic analyzer that can interpret certain variable conditions of a transport, such as a tractor trailer, moving along a road or highway. The data can be used to determine when to apply supplemental power to the wheels of a trailer to reduce fuel usage. One example device may include at least one of a power source affixed to a trailer to capture energy from movement of an axle of the trailer, and a motor powered by the power source to operate and provide movement assistance to the axle.

A power control system may include at least one of batteries, a motor, and a data logic analyzer that can interpret certain variable conditions of a transport, such as a tractor trailer, moving along a road or highway. The data can be used to determine when to apply supplemental power to the wheels of a trailer to reduce fuel usage. One example device may include at least one of: a power creation module that generates electrical power, a battery which store the electrical power, a motor affixed to a trailer axle of a trailer which provides a turning force to the trailer axle when enabled to operate from the stored electrical power of the battery, and a motor controller configured to initiate the motor to operate according to a predefined sensor condition.

An active hood vent system for a motor vehicle includes a hood vent, having a closure displaceable between a closed position and an opened position, and a control module. That control module is configured to adjust the aero balance of the motor vehicle by opening and closing the closure. Further, the control module may be configured to close the closure and thereby minimize engine compartment air from entering an HVAC inlet of the motor vehicle when the current operating temperature of the motor vehicle is below a predetermined temperature requiring engine cooling, and a current motor vehicle speed is below a predetermined speed where airflow over the hood limits ingestion of engine compartment air by the HVAC inlet.

A wheel fastener alarm is provided with a fastener body, a cap covering the fastener body, a sensor array disposed within the fastener body, and a cover disposed over an opening in the fastener body and a hole in the cap.

A method of monitoring a vehicle includes monitoring a precollision fuel level, detecting a collision event, and detecting a vehicle orientation based at least on the precollision fuel level and a postcollision fuel level. The method can be executed by a controller having a processor and a memory storing processor-executable instructions where the processor is programmed to monitor the precollision fuel level, detect the collision event, and detect the vehicle orientation based on at least a precollision fuel level and a postcollision fuel level.
