An apparatus for determining a wheel alignment change of a vehicle may include: a straight driving situation detection unit configured to detect whether a vehicle is going straight, based on information on positions of objects on a road and a yaw rate and steering angle; a wheel alignment change detection unit configured to detect a wheel alignment change based on lane information acquired from a camera sensor of the vehicle, when the vehicle information detected by the straight driving situation detection unit indicates that the vehicle is going straight; a driver alarming unit configured to output an alarm to a driver when the detected wheel alignment change is larger than a preset threshold value; and a wheel alignment change compensation unit configured to compensate for steering for SCC or LKAS control, when the detected wheel alignment change is smaller than the threshold value.

A wheel clamp (2) for fastening to a wheel (1), in particular to a wheel (1) of a motor vehicle, comprises at least two arms (22, 23, 24) which extend outward from a center (28) of the wheel clamp (2) in a radial direction, and a central rotary element (40) which is rotatably arranged in the center (28) of the wheel clamp (2). Each arm (22, 23, 24) has at least one movable element (32, 33, 34) which is movable in the radial direction in order to permit varying the length of the arm (22, 23, 24) in the radial direction. The wheel clamp (2) comprises furthermore at least two coupling elements (52, 53, 54) which each extend between one of the movable elements (32, 33, 34) and the central rotary element (40) such that the movable elements (32, 33, 34) are movable in the radial direction by rotation of the rotary element (40).

A set of light-weight adaptor assemblies suitable for use with optical targets, angle sensors, or other instrumentation. A first configuration of adapter assembly within the set is easily secured against the outboard surfaces a large-diameter vehicle wheel assembly having a highly convex raised central hub region, without concern for precise axial alignment or centering, while a second configuration of adapter assembly within the set is easily secured against the outboard surfaces of a large-diameter vehicle wheel assembly having a highly concave recessed central hub region, without concern for precise axial alignment or centering.

A wheel holder (1) for clamping attachment to a wheel (9), in particular to a wheel (9) of a motor vehicle, and for attaching a target (5) for vehicle wheel alignment measurement, comprises a base body (10) having a central portion and at least two, in particular three, arms (22, 23, 24) extending radially outwards from the central portion of the base body (10). Each of the arms (22, 23, 24) has a movable element (32a, 33a, 34a) which is movable relative to the base body (10) in the radial direction in order to vary the length of the arm (22, 23, 24) in the radial direction; a pressure element (52, 53, 54), in particular a compression spring, which is arranged and adapted to push the movable element (32a, 33a, 34a) outward in radial direction; and a traction element (62, 63, 63) mechanically coupled to the moveble element (32a, 33a, 34a) and arranged and adapted to pull the movable element (32a, 33a, 34a) inward in radial direction. The wheel holder (1) further comprises a coupling element (60) that mechanically couples the traction elements (62, 63, 63) of the at least two arms (22, 23, 24) to each other.

A bracket for wheel alignment control instruments for vehicle wheels includes a central body having a center, an outer face and an opposing parallel inner face facing a wheel; three gripping arms, the ends of which are distal to the center, have grip members and are simultaneously slidingly mounted onto the central body to slide in radial directions, driven by a first drive system and guided by first guide devices between wheel gripping or releasing positions; spacers holding the bracket, parallel to one side of the wheel, which are simultaneously movable in radial directions relative to the center through adjustable abutment positions, the spacers being slidingly mounted onto the central body to slide independent of the arms, driven by a second drive system independent of the first drive system and guided by the first guide devices.

A vehicle monitoring system includes a controller and one or more wheel-integrated monitoring devices that are each disposed between a wheel of a vehicle and a tire that is mounted to that wheel. The wheel-integrated monitoring device has multiple sensors, a transceiver, and a power unit. The sensors generate different measurements during each rotation of the wheel. The transceiver wirelessly transmits the different measurements to the controller. The power unit provides power to the sensors and the transceiver. The controller analyzes the measurements and generates alerts on a dashboard or console in response to the measurements revealing wheel alignment, tire tread, and/or other driving characteristics that differ from manufacturer specifications by more than a threshold amount or that present safety hazards to the driver.
