A system used to control the orientation of a vehicle's suspension. The system includes a control system receiving input data from a plurality of sensors concerning the relative motion, speed, and orientation of the vehicle. The control system is configured to process the input data and actively control the orientation of the suspension system by selecting a suitable driver speed and tilt angle according to external conditions.

A suspension device for a non-steered driving wheel in which an in-wheel motor for driving the driving wheel is incorporated in a wheel carrier and which includes suspension arm pivotally supported on a vehicle body at one end and connected at the other end to the wheel carrier via at least two elastic bushing devices. A principal elastic axis which is determined by the at least two elastic bushing devices and extends vertically passes through a grounding area of the driving wheel.

A suspension device for a non-steered driving wheel including a wheel carrier having an in-wheel motor incorporated therein for driving the driving wheel, and a suspension arm pivotally supported on a vehicle body and connected to the wheel carrier by a connecting structure. The connecting structure includes a plate member fixed to the wheel carrier by fastening and a pair of elastic bushing devices attached to the plate member. The suspension arm has an open cross sectional portions for receiving portions of the plate member and the elastic bushing devices, and the elastic bushing devices are fixed to the open cross sectional portions at both ends.

The present invention field relates to a braking device of the tilting system of vehicles that have at least three wheels and can lean sideways by virtue of the presence a so-called wheel tilting system. The device is characterized in that it comprises an electronic control unit adapted to receive and process a plurality of signals coming from devices capable of detecting parameters related to the instantaneous dynamic behavior of the vehicle and to selectively actuate said braking means.

The present invention discloses a three-wheeled motor vehicle having a lockable tilting mechanism. The tilting mechanism is configured to tilt the vehicle at any angle without the need for a driver to put their feet on the ground outside the vehicle. The tilting mechanism is further configured to lock the tilting of the vehicle at any desired angle by the driver. The present invention enables the driver to alter the lean from within the vehicle if the lean is locked in an undesirable position. The tilting mechanism is further configured to enable the driver to lock or unlock the lean of the vehicle in a manner that allows the driver to intuitively switch between steering and counter-steering.

An automatic tilting vehicle including a pair of wheels rotatably supported by wheel carriers and laterally spaced apart and a vehicle tilting device that tilts the vehicle to the inside of a turn when turning. The vehicle tilting device includes a swing member, an actuator that swings the swing member about a swing axis, and a pair of connecting rods pivotally attached to the swing member and the wheel carriers on both lateral sides of the vehicle. Each connecting rod has a preset weakest portion that is buckled to be deformed in a preset direction in a preset area when a buckling load equal to or larger than a preset value is applied.

A vehicle is configured to travel, when a vehicle velocity is within a velocity range from not less than a first velocity of at least zero to not more than a second velocity larger than the first velocity, in a mode in which a vehicle body is leaned by a lean mechanism according to an input into an operation input unit, and a wheel angle of a turn wheel changes following a lean of the vehicle body. A natural frequency of roll oscillation of the vehicle body is either within a range of smaller than a reference frequency or within a range of larger than the reference frequency, the reference frequency being a frequency at which oscillation of the wheel angle of the turn wheel has phase delay of 90 degrees relative to the roll oscillation of the vehicle body in its width direction.

A structure of rocking controller of a saddle riding type vehicle includes a rocking lock mechanism configured to lock lateral rocking of the vehicle body; wherein the rocking lock mechanism includes an arc shaped lock plate which crosses with an axial direction of a rocking shaft of the vehicle body and a lock caliper configured to lock a relative rocking between the lock plate and the lock caliper by clamping the lock plate, and a motor for the actuator is arranged in front of the rocking lock mechanism and the rotating drive shaft of the motor is arranged so as to penetrate an inner circumferential region of the arc shaped lock plate.

A passenger vehicle provided with a steering handle (15) and configured such that an attitude angle of the driver seat surface (14a) relative to a horizontal reference plane is changeable, so that a first attitude changing operation switch (25) and a second attitude changing operation switch (26) for changing the attitude angle are disposed in such positions as to be operable with a thumb of the driver of the vehicle from a steering handle grip (18) of the steering handle (15).

A vehicle includes: a vehicle body; three or more wheels; an operation input unit to be operated to input a turning direction; and a lean mechanism for leaning the vehicle body in its width direction. Within at least partial range of vehicle velocity, the vehicle is configured to travel in a mode in which the vehicle body is leaned by the lean mechanism according to an input into the operation input unit, and a steering angle of a steered wheel changes following a lean of the vehicle body. And, the vehicle includes a changing device for changing a turn resistance force acting between the vehicle body and the steered wheel.
