Three-wheeled tilting vehicle

A tiltable vehicle is configured to transform between an autonomous mode and a rideable mode by pivoting the handlebars and steering column of the vehicle about a pitch axis. In the autonomous mode, the steering column is folded back toward the chassis and a tiltable chassis of the vehicle is prevented from tilting. In the rideable mode, the steering column is unfolded and the chassis is free to tilt. In some examples, a tiltable vehicle includes features beneficial for vehicle-sharing, such as parking devices or a basket. These features may be included on any suitable vehicle and are not limited to use on transforming vehicles.

Tilting Wheeled Vehicle
20230040278 · 2023-02-09 ·

A tilting, preferably three-wheeled, vehicle is disclosed that has a tilting mechanism and a universal steering linkage that allows the vehicle to have leaning and steering characteristics substantially similar to those offered by an in-line two-wheeled vehicle, but that does not require complex linkages and/or control systems to operate effectively. A tilting linkage is operably secured to a frame to allow a pair of spaced apart wheels to remain substantially aligned with the plane of the vehicle throughout its range of movement while still providing an increasing camber between the wheels as tiling of the vehicle increases. A tilting lock system may be provide to limit tilting of the vehicle upon predetermined criteria.

MOTOR VEHICLE CONTROL
20230088275 · 2023-03-23 · ·

A vehicle (1) having: a chassis portion (2) and a tilting suspension arrangement (10) such that the chassis portion can tilt relative to ground; a tilt control arrangement (50) including at least a tilt controller and a tilt motor (48) to selectively apply a torque between the chassis portion (2) and at least one member (12) of the tilting suspension arrangement (10). The tilt controller has an active, tilt-controlled first mode (200) which adjusts a tilt angle (a) of the chassis towards an unstable equilibrium position using the tilt motor (48). The tilt controller has a primarily passive, free-tilt second mode (220) in which the tilt angle of the chassis is not adjusted for at least fifty percent of time. The tilt controller selectively permits a transition between the first mode and the second mode in dependence on at least one operating parameter of the vehicle.

A vehicle small in width and capable of ensuring both driving stability and drivability includes: a vehicle body with two or more wheels including steered wheels (right front wheel, left front wheel) for steering; an inclination angle detection part that detects the inclination angle of the vehicle body about a roll axis thereof; and a torque applying part (turning mechanism) that applies a steering torque to the steered wheels in accordance with an inclination angular velocity or an inclination angular acceleration of the vehicle body calculated from the inclination angle.

THREE-WHEEL MOTOR VEHICLE AND CONTROL SYSTEM
20230060705 · 2023-03-02 ·

A three-wheeled vehicle having a front wheel assembly attached to a chassis. The chassis includes a rotational control shaft having a rotational axis that is generally directed in a longitudinal direction of the vehicle. The rotational control shaft is integrated with or secured to the chassis in a non-rotational manner and passes through the front wheel assembly in a rotationally-free manner, such that the rotational control shaft can rotate about its rotational axis. The front wheel assembly includes one or more lean control motors, which are operably configured to rotate the rotational control shaft about its rotational axis thereby causing the chassis to lean from side to side to improve the handling ability of the vehicle. Some embodiments include a lean control system configured to automatically control the degree of rotation of the chassis.

Autonomous tilting delivery vehicle

An autonomous tilting three-wheeled vehicle comprises a pair of front wheels coupled to a tiltable chassis by a mechanical linkage, such that the pair of wheels and the chassis are configured to tilt in unison with respect to a roll axis of the chassis. An electronic controller of the autonomous vehicle controls a tilt actuator to selectively tilt the chassis. Optionally, a steering actuator is coupled to the front wheels and controlled by the electronic controller to selectively steer the wheels. A sensor configured to measure orientation-dependent information may be coupled to the chassis by a gimbal configured to compensate for vehicle tilt. In some examples, the autonomous vehicle comprises an autonomous delivery robot.

TILTABLE CHASSIS FOR A THREE-WHEELED VEHICLE
20220324285 · 2022-10-13 ·

A three-wheeled vehicle may include one rear wheel and two front wheels coupled to a tiltable chassis, such that tilting of the chassis causes a corresponding tilting of the three wheels. The tiltable chassis includes a tiltable body coupled to a non-tilting frame by a pair of rotatable joints, such that the tiltable body is configured to rotate relative to the frame. A fore-and-aft connecting beam of the tiltable body extends beneath the frame to accommodate a battery compartment or other storage on top of the frame. A front tower extends upward from a front end of the connecting beam, above the frame, to couple to a tilt linkage and seat post of the vehicle. A rear tower extends upward from a rear end of the connecting beam to retain the rear wheel.
