A unit for rapid deployment and retraction of chain traction systems for vehicles includes a pneumatic cylinder having a cylindrical chamber enclosing a piston that is pneumatically-movable bidirectionally. A control rod coupled at one end to the piston passes through an end of the chamber and is coupled to a rack linearly movable within a sealed, grease-containing case. The rack is formed from a series of equally-spaced roller pins secured between parallel walls of a rack frame. The roller pins of the rack engage a sprocket affixed to a rotatable shaft to which is rigidly coupled an actuator arm of the rapidly-deployable vehicle ice and snow chain traction system. As the rack is moved back and forth, the actuator arm swings through an arc that—depending on the displacement of the control rod and the length of the rack, can be greater than 180 degrees.

A steering control method and system for a vehicle may determine whether the snow chain has been mounted by comparing the number of times of vibrations of a certain peak or more detected by respective wheel speed sensors with respect to a current vehicle speed with a predetermined value, and selectively controls the operations of an AFS and a RWS according to the position of the wheel on which the snow chain has been mounted, when it is determined that the snow chain has been mounted.

The present application discloses a vehicle rescue device, a rescue plate and a support plate, and relates to the field of cross-country equipment. The vehicle rescue device includes a first rescue plate and a second rescue plate, at least one end of the first rescue plate is provided with a first connecting portion, at least one end of the second rescue plate is provided with a second connecting portion, and the first connecting portion is detachably connected with the second connecting portion.

Presented are hybrid metal and fiber-reinforced polymer (FRP) composite wheels for vehicle wheel assemblies, methods for making/using such wheels, and motor vehicles equipped with such wheels. A wheel for a motor vehicle wheel assembly includes a wheel face with multiple spokes that are circumferentially spaced about and project radially outward from a central hub. The central hub rotatably attaches to the vehicle's body, e.g., via a corner module. The wheel face is fabricated, e.g., as a one-piece structure, from an FRP material. A wheel barrel, which circumscribes the wheel face, includes an annular rim that mounts thereon an inflatable tire. The wheel barrel is fabricated, e.g., as a one-piece structure, from a metallic material. Multiple overmold through holes and/or inset tabs are circumferentially spaced about the annular rim. The FRP material extends through and/or surrounds the overmold through holes/inset tabs and thereby mounts the wheel face to the wheel barrel.

A wheel traction device is adapted for providing traction for a wheel of a vehicle to escape from a mud ground during rotation of the wheel, and includes: a guiding unit having a guiding portion adapted to abut against the wheel; a bearing unit that is detachably connected to the guiding unit, and that has a bearing portion adapted to be positioned on the mud ground such that, during rotation of the wheel, the bearing unit and the guiding unit are prevented from being driven by the rotation of the wheel to move relative to the mud ground, thereby allowing the wheel to roll over the bearing portion under guidance of the guiding portion; and a fastening unit that detachably fastens the bearing and guiding units together.

A vehicle braking force control apparatus of the disclosure executes a slip rate reduction control to reduce a slip rate of any of wheels of a vehicle becoming equal to or greater than a predetermined slip rate threshold by automatically changing braking force applied to one or more of the wheels. The apparatus uses a first slip rate threshold as the predetermined slip rate threshold during a normal acceleration-and-deceleration control and a normal steering control. The apparatus uses a second slip rate threshold during a driving assist control. The second slip rate is set to a value smaller than the first slip rate threshold and near and smaller than the slip rate, at which a friction coefficient between the wheel and a surface of a road on which the vehicle moves is maximum.

An apparatus for applying a force to a vehicle (2) on a track (4), the apparatus comprising one or more magnets (6), the one or more magnets being rotatably mountable with respect to at least part of the vehicle. The track comprises one or more electrically conductive portions and the magnets are configured such that their rotation relative to the track induces one or more electrical currents in the track, such that a force is applied to the vehicle.
