摘要： 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.

摘要： A vehicle of the present disclosure may include at least one pair of opposing wheels coupled to a tiltable central chassis by a four-bar linkage or the like, such that the wheels are configured to tilt in unison with the central chassis. A steering actuator and/or a tilting actuator may be discretely controllable by an electronic controller of the vehicle. The controller may include processing logic configured to maintain alignment between a median plane of the chassis and a net force vector caused by gravity and any induced centrifugal forces. Various control algorithms may be utilized to steer the vehicle along a desired path, either autonomously or semi-autonomously.

摘要： 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.

摘要： A vehicle with a base frame to which at least two sprung suspensions, in particular sprung wheel suspensions, for driven, non-driven, steerable or non-steerable contact elements, for example wheels, are attached which can be steered by means of a steering knuckle and are located on both sides of the longitudinal direction of travel, in each case transversely to the direction of travel, a tilt frame, tiltable in a tilt axis with respect to the base frame. A steering tube is rotatably attached to the tilt frame in the steering axis and automatically tilts with the tilt frame, at least one track rod connected to the track rod actuating element, and a linear or rotary track rod actuating element rotatable over a guide element. The track rod actuating element is displaced by tilting the tilt frame about the tilt axis and independently thereof by rotating the steering tube about the steering axis in such a way that the steerable contact element is given a steering movement by the track rod actuating element by means of the at least one track rod and no substantial change in the camber of the contact elements takes place during cornering, wherein the vehicle comprises at least one spring damper system which is suitable and provided for reducing a pendulum tilt of a tilt frame about the vertical zero position.

摘要： A vehicle includes a control switch that is configured to generate an operation signal, and a controller that is electrically connected to the control switch to receive the operation signal therefrom, and that is configured to, in response to receipt of the operation signal, transmit a control signal to a tilting mechanism for making the tilting mechanism operate in one of a locked state and an unlocked state. After the vehicle is powered on, the controller is further configured to, when the controller has continuously received the operation signal for a predetermined reception time, determine that the control switch is abnormal, stop transmitting the control signal and control a warning unit to output a warning signal.

摘要： This invention relates to a rolling motor vehicle with three or four wheels, comprising a frame 6 that extends from a forecarriage 8, which supports at least two front wheels 10′,10″, to a rear 12 which supports one or more rear wheels 14. The frame 6 defines an accommodating area 15 for a driver P. The forecarriage 8 in turn comprises: —a forecarriage frame 16; —at least one pair of front wheels 10′,10″ kinematically connected to each other and to the forecarriage frame 16 by means of a rolling kinematic mechanism 20 which enables the front wheels to roll in a synchronous and specular manner, each wheel 10′,10″ being connected to said rolling kinematic mechanism 20 by means of a respective axle journal 60, said axle journal 60 being mechanically connected to a rotation pin 68 of the wheel in order to support it rotatably around an axis of rotation R′-R′, R″-R″; —a roll control system 100 of the motor vehicle; —suspension means 90 which guarantee each axle journal 60 at least one spring suspension movement with respect to said rolling kinematic mechanism 20. The roll control system comprises a rod 110, which connects the two front wheels directly to each other at the respective axle journals 60 at its two ends by means of hinging means 72,73,74 which enable said rod 110 to passively follow the movements of the axle journals 60, the roll movements of the two front wheels and of the respective axle journals causing changes in the lying position of said rod 110 with respect to a vertical projection plane, which is transverse to a centre line plane M-M of the motor vehicle. The rod 110 is usable directly or indirectly by the driver P as a command element of the roll control system 100 to control the rolling movements of the two front wheels without having to put his feet on the ground, adjusting the lying position of the rod 110 itself with his own body. Said command element 110, 120 is disposed so as to be accessible and maneuverable by the driver P from the accommodating area 15.

摘要： The roll induces four wheel steering vehicle employs a frame system to protect the driver and serves as an attachment point for, independent suspension links pivotally connect to the wheel assemblies enabling four wheel independent suspensions. A mechanically manipulated centrally mounted steering and suspension pivot, provides both steering control and suspension attachment for the shock and spring. The device is controlled by the driver using typical steering wheel and pedal movement. Steering movement by the driver produces proportionally appropriate camber, steering angle, and roll simultaneously. The invention provides a feeling of integration with the vehicle as the driver rolls into turns with the vehicle, while minimizing fatigue caused by the continuous resistance to centrifugal cornering forces.

摘要： The vehicle includes: a chassis which includes a front cross-member and a rear cross-member; a nacelle receiving a person or a load, pivotally mounted relative to the central part of the cross-members about a substantially longitudinal hinge axis, the center of gravity of the nacelle being situated below said hinge axis; a front train and a rear train, each including two movement supports on the ground, each movement support being connected to the end part of the corresponding cross-member by a connecting system; the cross-members, situated in the upper part of the nacelle, being separate pieces linked together only by the nacelle, via the hinge axis, so as to be able to pivot about the hinge axis independently of one another.
