Abstract: An all terrain vehicle, also known as an ATV, has a seat designed to comfortably accommodate a rider over a wide variety of rugged terrain. The seat is profiled so that the rider may easily shift body weight and lean with the vehicle while traversing steep and uneven terrain. The seat has a dip and taper positioned beneath a riders' knee and lower thigh to provide the profile. The ATV is also provided with front fenders and mud flaps to protect the rider from debris. The fenders rotate with the wheel to provide the rider with maximum wheel visibility and access. The fenders can also be releasable, thereby rotating around the axis of rotation of the front wheels to break free from obstacles and provide easy access to the wheels beneath the fender. The ATV provides exceptional rider comfort and control.

Abstract: A vehicle (1) provided with a frame having two frame sections (3,4) which are able to tilt with respect to one another. An opposite steer power transmitter (50) is connected to a steerable front wheel (13). The opposite steer power transmitter (50) is controlled as a function of the tilting moment on the frame sections (3,4). By this means, application of opposite steer is achieved, as a result of which the tilting section of the vehicle “drops into the bend” more rapidly and as a result of which increased maneuvrability is obtained. The opposite steer power transmitter (50) can be used on vehicles having an active tilting system with, for example, hydraulic tilting cylinders (9,9′), which are controlled by a sensor depending on the radius of the bend (24). The tilting moment generated by the tilting cylinders (9,9′) can optionally serve as a control signal for the opposite steer power transmitter (50).

Abstract: A controlling apparatus for representing the motion of a normal wheeled omni-directional vehicle (ODV) in a relative coordinate system, and for effectively controlling the ODV and a controlling method thereof. Drive wheels are connected to four corners of the body of the ODV through offset links that can be independently steered. With the offset links, even if the body stops, it can be reoriented without a need to perform a forced direction change operation. The traveling speed of the body, the turning radius of the body, and the angle between the horizontal axis of the body and the traveling direction thereof are defined as relative variables of a relative coordinate system. With these relative variables, the motion of the ODV is designated. The designated motion of the body is converted into the time change or the displacement (drive speed) and the steering angle of each wheel by inverse kinematics. The corresponding control signals are sent to a driving unit of the wheels.

Abstract: A side car for a motorcycle, wherein the side car box overlies the side car wheel directly thereabove. The lateral coupler between the side car and the motorcycle biases the side car wheel to incline interiorly of a curve, together with the motorcycle wheels, upon the moving vehicle taking a curve on a road. The side-car frame and box axially roll with the wheel, whereby the side-car center of gravity remains continuously within the plane of its wheel. As the motorcycle wheels progressively axially roll, their angular value relative to the vertical plane will increase relative to a second angular value corresponding to the roll of the side-car wheel relative to the vertical plane.
