摘要： A vehicle is provided with a vehicle body, N (N is an integer equal to or larger than 2) wheels including one or more front wheels and one or more rear wheels, a force generator, and a force controller. The N wheels include one or more turn wheels turnable in the width direction of the vehicle. The force generator is configured to generate a force which changes a yaw angular acceleration. The force controller is configured to control the force generator. A gravity center of the vehicle body is located away from a rotation center of the vehicle toward front side or rear side when the vehicle turns. The force controller controls the force generator to control a roll torque in the width direction acting on the vehicle body.

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 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： The present steerable wheel assembly incorporates a lean-to-steer mechanism into an inner race of a roller bearing, while a wheel is mounted to an outer race of the roller bearing. A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not proportionally responsive to tilting over the expected range of tilting.

A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not consistently responsive to tilting over the expected range of tilting. The present non-linear lean-to-steer mechanisms can also be incorporated into alternative lean-to-steer devices, and alternative mechanisms can employ tracking structures to coordinate tilting motion of a first moving element with steering motion of a second moving element to provide a non-linear lean-to-steer response.
