Provided are a vehicle control apparatus and a vehicle control method, a vehicle control apparatus including: a sensor configured to sense at least one of a vehicle speed value and a lateral acceleration value of a vehicle; an active camber device including a knuckle for supporting a wheel of the vehicle, an upper arm having one end rotatably connected to the knuckle to form a stroke node, and a actuator for rotationally shifting the stroke node of the upper arm with respect to a connection point with the knuckle in a vertical direction; and a controller configured to vary a position of the stoke node of the upper arm through the actuator on the basis of one of the sensed vehicle speed value and the sensed lateral acceleration value.

An active geometry control suspension may include a first link having one side connected to a wheel carrier engaged to a wheel and the other side extending along a width direction of a vehicle; a second link having one side connected to the wheel carrier and the other side extending in the width direction of the vehicle; a first lever having one side connected to the other side of the first link; a second lever having one side connected to the other side of the second link; a connection lever connecting the other side of the first lever and the other side of the second lever; and an actuator connected to the connection lever.

A damper assembly includes an outer cylinder, an inner cylinder, a plunger, a passage, and a piston. The inner cylinder is positioned at least partially within the outer cylinder and has a cap attached to one end thereof. The plunger is positioned radially inward from the inner cylinder and coupled to a rod. The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The passage extends through the rod and is fluidly coupled with the first chamber. The piston is coupled to the inner cylinder and extends radially outward toward the outer cylinder. The piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber. The plunger is configured to move relative to the inner cylinder, and the piston is configured to move relative to the outer cylinder.

Provided is a vehicular suspension device that achieves both of improvement in driving stability and improvement in vehicle movement performance. The vehicular suspension device includes a suspension capable of adjusting a roll center height by control of an actuator, and a roll center controller. The controller includes a traveling state corresponding height determination unit configured to determine the roll center height of the suspension in accordance with a predetermined rule on the basis of vehicle speed information and road surface information, and an actuator controller configured to control the actuator so that the roll center height reaches the roll center height determined by the unit.

A wheel suspension system is disclosed. The wheel suspension system may include a suspension assembly that may include a sub-frame adapted to be connected to a reference frame of a vehicle, a wheel interface adapted to rotatably support a wheel of the vehicle and to define a wheel rotation axis and a wheel rotation plane, and one or more linking units. Components of the linking unit(s) may be pivotally connected to each other, to sub-frame and to the wheel interface using pivoting connection that may cause components of the linking unit(s) to rotate about axes that are substantially perpendicular to the wheel rotation axis. The components of the linking unit(s) may be dimensioned, and positions of the pivoting connections may be set to cause a substantially linear motion of the wheel interface along a reference wheel interface motion axis that is perpendicular to the wheel rotation axis.

A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

A bushing includes a body that is cylindrical; a bore through the body; a channel extending along an inner face of the bore; and a groove on a substantially planar surface of the bushing and including a first end intersecting with an end of the channel and a second end extending radially from the bore.

A suspension structure of a utility vehicle includes a frame, a wheel, and a trailing arm including an arm extending anteroposteriorly and supported by the frame, a knuckle rotatably supporting the wheel, and a rotary shaft configured to angularly displace the knuckle in a vehicle width direction with respect to the arm.

A suspension device (rear suspension (10)) for vehicles is provided which includes a damper (40), a shaft (50) pivotably supporting an end of the damper (40), and a bush (60) including a cylindrical elastic member fitted onto the outer circumference of the shaft (50). The axis (C2) of the bush (60) is disposed along a line of intersection between an imaginary first plane (S1) and an imaginary second plane (S2), or along a line parallel to the line of intersection. The first plane (S1) is orthogonal to the axis (C1) of the damper (40) when a stroke position of a wheel (24) is a first position relative to the vehicle body (80) in the vertical direction of a vehicle body (80). The second plane (S2) is orthogonal to the axis (C1) of the damper (40) when the stroke position of the wheel (24) is a second position.

A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.
