A leaning vehicle has a frame pivotally connected to the lower end of a shock tower, the pivotal connection defining a frame leaning axis wherein the frame is adapted to lean to a right side and to a left side relative to the shock tower about the frame leaning axis. The leaning vehicle includes an actuator operatively connected to the frame and to the shock tower which is adapted to impart a leaning motion to the frame relative to the shock tower about the frame leaning axis.

A method of operating a leaning vehicle is described. The method includes: determining a steering torque exerted on a steering assembly; determining a speed of travel of the vehicle; determining a leaning angle of a frame of the vehicle with respect to a reference angle; and exerting a leaning torque on the frame relative to a pivotable frame member about a pivot axis in a first direction using an actuator in response to a steering torque exerted on the steering assembly in a second direction opposite the first direction when a speed of travel of the vehicle is above a threshold speed, thereby causing the vehicle to turn in the first direction.

A watercraft trailer has a releasable connector for releasably connecting a watercraft to the trailer. The releasable connector has a lever pivotally connected to a connector support and a hook connected to the lever. Pivoting of the lever towards a front of the trailer moves the releasable connector to a locked position and pivots the hook towards the front of the trailer. A locking mechanism prevents the releasable connector from moving to an unlocked position by applying forces to any one of the lever and the hook that would otherwise pivot the lever and the hook towards a rear of the trailer. Unlocking the locking mechanism moves the releasable connector to the unlocked position and pivots the hook towards the rear of the trailer. A method of securing a watercraft to a watercraft trailer and a method of releasing a watercraft from a watercraft trailer are also disclosed.

The present invention provides a three-wheel vehicle (10) having an electronic vehicle stability system and a method for stabilizing a three-wheel vehicle. The three-wheel vehicle (10) features a left (22) and right front wheel (24) laterally spaced apart and a single centered rear wheel (18) each having a tire contact patch which together define a triangular pattern of contact tire patches defining left and right rollover axis. The electronic vehicle stability system is adapted to calculate a dynamic status of the vehicle (10) based on inputs received from sensors and to output signals to the braking system to generate a specific moment about one of the left and right rollover axis when the calculated dynamic status of the vehicle exceeds a predetermine threshold indicative of a precursory condition of rollover. The present invention also provides a three-wheel vehicle having a yaw sensor positioned within a radius of 25 cm about the vertical axis (Z) to improve the accuracy of the yaw measurements provided to the electronic vehicle stability system.
摘要:
A three-wheeled vehicle having a pair of front wheels and a single rear wheel is provided with an electronic stability system (ESS) to control certain operating parameters of the vehicle based on sensed inputs from the three wheels. Preferably, the three-wheeled vehicle has a straddle type seat, an internal combustion engine, and road tires suitable for conventional road use.

An all-terrain vehicle with improved stability is provided. The all-terrain vehicle includes a frame that is substantially centered on a longitudinal centerline of the vehicle, an engine, a plurality of wheels that are attached to a front axle and a rear axle, a handle bar that is operatively connected to at least two of the wheels, and a straddle seat. A fuel tank is fluidly connected to the engine, and is disposed forward of the rear axle, substantially above a rear suspension pivot point, and below the seat, and is substantially centered on the longitudinal centerline, thereby improving the stability of the all-terrain vehicle.
摘要:
A method for enhancing stability of a three wheel vehicle having a pair of front wheels and a single rear wheel, each of the wheels having a tire with a tire grip threshold. The method including deploying an electronic stability system (ESS) on the vehicle, providing the ESS with input from various vehicle sensors related to the longitudinal and lateral acceleration of the vehicle, causing the ESS to determine whether (i) a precursory condition indicative of a wheel lift exists and (ii) the tire grip threshold of any of the tires has been exceeded; and when a precursory condition indicative of a wheel lift exists and the tire grip threshold of none of the tires has been exceeded, causing the ESS to reduce the longitudinal acceleration of the vehicle by a first amount less than that which would cause the tire grip threshold of any of the tires to be exceeded.
