A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle or a coupling between a vehicle body and a suspension of the vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow and vehicle weight sensing coupling devices installed on different types of automobile cars and trucks.

A vehicle rear structure includes an interposed member and an attachment part. The interposed member is disposed at a center area in a vehicle width direction of the vehicle under a floor panel of a vehicle body of the vehicle, and interposed between at least one under-floor component of the vehicle and the vehicle body. The attachment part is provided for a hitch member for a trailer. The attachment part is disposed at a rear end of the interposed member and at a center area of the interposed member in the vehicle width direction.

Methods and apparatus for a dual reacting, single load sensing element coupled to a hitch receiver are disclosed herein. An example apparatus includes a hitch configured to be coupled to a vehicle, the hitch including a crossbar, a receiver tube, and a pin housing coupled to the receiver tube. The pin housing includes a first pin including a load sensor, the first pin reacting loads in a first direction and a second direction and a second pin, the second pin reacting loads in the first direction, the first pin and the second pin acting as the only load path between the receiver tube and the crossbar.

Trailer electrical connector assemblies can facilitate the automatic coupling and decoupling of a trailer. A trailer electrical connector assembly can include a vehicle portion and a trailer portion. The vehicle portion can include a hitch ring that is secured to a hitch ball and guides within which contacts are positioned. The trailer portion can include a sleeve that is positioned around a coupling mechanism of the trailer and a sleeve ring that forms receivers within which contacts are positioned. When the hitch ball is inserted into the trailer's coupling mechanism, the receivers can be automatically coupled with the guides to thereby form an electrical connection between the vehicle and the trailer.

A vehicle includes a vehicle frame. The vehicle frame includes a frame rail elongated along a vehicle-longitudinal axis that defines a hole. The vehicle includes a trailer hitch mount supported by the frame rail. The vehicle includes a face plate supported by the trailer hitch mount that defines an opening extending through the face plate that is aligned with the hole of the frame rail. The trailer hitch mount extends through the opening and is completely surrounded by the face plate. The trailer hitch mount extends into the hole of the frame rail along the vehicle-longitudinal axis.

Methods and apparatus are disclosed for a three-point attachment trailer hitch. An example hitch includes a crossbar including a first end and a second end, the first end or the second end including at least one tab protruding from an edge of the first end or the second end, and a first endplate positioned on the first end or the second end of the crossbar using the at least one tab, the endplate including a first threaded hole and a second threaded hole, a diameter of the second threaded hole larger than a diameter of the first threaded hole.

In an embodiment a towing pipe connection structure includes a vehicle body rear member including an aluminum material, a towing pipe at least partially including an aluminum material and a connection bracket including a bumper back beam plate in contact with a back panel of a vehicle body and including an insertion hole into which the towing pipe is inserted, an engage plate having an engage hole to which the towing pipe is connected and a connection plate connecting the bumper back beam plate and the engage plate, wherein the connection bracket is connected to a rear member of the vehicle body, and wherein the connection bracket includes an aluminum material.

Methods and apparatus are disclosed for a load-sensing hitch utilizing a system of strain gauges. An example apparatus includes a receiver tube, a side member, a crossbar coupled to the receiver tube and the side member, the cross including a support including a first end, a second end and a mid-portion located between the first end and the second end, the mid-portion having a cross-sectional area smaller than the cross-sectional area of the first end or the cross-sectional area of the second end and a strain gauge disposed within the mid-portion.

A hitch receiver with four walls forming a tube that includes an integrated clamping device for immobilizing inserted accessories. A flexible tube wall acts as a pressure plate to press against the accessory as force is applied. The clamping device further utilizes a backstop attached to a rigid portion of the tube and accommodating a mechanism for generating force. Force can be generated mechanically via a threaded rod operatively connected to a threaded opening in a block located in the space between the backstop and the pressure plate. Clamping force is applied to the pressure plate by the tip of the threaded rod as it is turned in such a way as to force the threaded block against the backstop. Force is applied until the pressure plate deforms, contacts the adjacent wall of the inserted accessory, and presses the accessory against the opposite tube wall.

In the case of a trailer coupling for motor vehicles, including a cross member, which is connectable to a motor vehicle body, and a bearing unit, which carries a ball neck that at a first end is connected to the bearing unit and at a second end carries a coupling ball, and a holding base, which carries the bearing unit and is connected to the cross member, it is proposed according to the invention that the holding base should have a flange unit, for receiving the bearing unit, and two holding elements that project from the flange unit and in so doing run at a spacing from one another and act on the cross member.
