Abstract: A stepwise brake control is automatically performed when TTC obtained according to a relative distance and a relative speed between a vehicle and an object is lower than a predetermined value. For example, a brake force or a brake reduction speed is gradually increased over a plurality of stages in time series. Moreover, the affect of speed change control to the automatic brake control is removed. Alternatively, automatic brake control is supported by the speed change control. Alternatively, the friction coefficient state is estimated, and the brake force or the brake speed reduction is adjusted according to the estimated result. Alternatively, an auto-cruse function is invalidated at least the final stage. Alternatively, when the brake force or the brake speed reduction generated by a brake operation by a driver is greater than the brake force or the brake speed reduction generated by the brake control means, the brake operation by the driver is handled with a higher priority than the stepwise brake control.

A force that deactivates a braking feature may be made adjustable, e.g., to accommodate riders of different weights or to provide different braking feature responses.

Abstract: A snow ski traction device includes a traction blade pivotally mounted on blade-to-ski attachment device so as to secure the blade to the side of a snow ski. The blade pivots through a pivot arc of substantially 90 degrees and is stopped from pivoting outside of that arc. At one end of the arc, the length of the blade is substantially parallel to the length of the ski; while at the other end of the arc, it is perpendicular to the length of the ski. When perpendicular to the ski, the blade engages with and presses backwards against snow or ice beneath the ski, thus propelling the wearer of the ski in a forward direction and preventing backward slippage of the ski. When parallel to the ski, the blade permits a full, forward sliding movement of the ski. The ordinary motion of the ski causes the blade to pivot as required between these parallel and perpendicular positions. This device, and its method of use, are particularly applicable for cross-country skiing, though can be used by downhill skiers as well.

In the region of the brake base (5), the screws (8) for securing the baseplate (1) to the ski bear exclusively on the baseplate, and the base (5) has openings (12) making it possible to access the screws (8) using a screwdriver. The ski binding may be sold fully preequipped, and it can be mounted very quickly on a ski without it being necessary to remove the brake beforehand. When sharpening the edges, the brake can be removed without compromising the securing of the binding to the ski.

Abstract: A skeg device and system and the like, for mounting on snowboards or skis to improve performance, maneuverability, tracking and balance. Skegs are designed to easily mount on snowboards, and has blades for controlling the snowboard path in a variety of snow conditions from powder, to hard snow, to ice. Each skeg is comprised of a mounting plate for easily installing the skegs on a snowboard and a blade rotably mounted on a shaft that is spring loaded. The spring loaded rotatable shaft allows the blades to deflect when engaging a hard surface to constantly self-adjust to snow conditions. Depth adjustment is provided by a thumbscrew that adjusts the rotational position of the shaft and thus, the depth that the blade extends below the surface of the snowboard. By rotating the thumbscrew, a rider can dial in the tracking of the blade on each skeg individually.

Abstract: A snowmobile ski-type runner braking system provides a braking "claw" at the trailing end of each snowmobile ski-type runner that can be activated by the operator from his console to pivot downward into digging engagement with the snow to help brake the snowmobile. The claws are activated in unison so that balanced braking force is applied to each trailing ski end on both sides of the snowmobile. Even with the claws extended into their digging mode, the operator can still steer by turning the skis. Each claw can be actuated by an electric motor and power screw mechanism mounted on the runner. Alternately, each claw can be actuated by a hydraulic piston/cylinder mechanism mounted on the runner.
