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.

The present invention is a hybrid crossover between an automobile and a motorcycle that is able to take tight corners almost like a motorcycle but is driven and handled like an automobile by optionally leaning into turns with one wheel in the front and two wheels in the rear of the vehicle and passenger compartment having an accelerator and brake pedals and steered with a steering wheel and gears that can be selected via a toggle switch gear selector located in the vicinity of the steering or by a floor and/or dash mounted unit.

A tilting vehicle having a steering system actively steering a front axle and a rear axle having two wheels that can be deflected individually in a vertical manner with respect to a vehicle body and that are independent of the steering system. The wheels of the rear axle can be steered by passive steering device configured to generate a steering force because of a vertical deflection of the wheels as the vehicle body tilts to one side. The steering force causing wheels to steer towards the opposite side.

An electric three wheeled vehicle includes a vehicle chassis supporting a vehicle operator seat or saddle. The vehicle chassis defines a storage region beneath the vehicle operator seat or saddle. One or more energy storage devices for powering one or more electric motors of the vehicle are located within the storage region and are supported by the chassis. The storage region and/or the energy storage device(s) each form an elongate three-dimensional volume having a long axis that is parallel to a longitudinal axis of the vehicle.

A saddle riding type vehicle includes left and right front wheels that unlock a linkage more surely when the vehicle starts. The vehicle includes a linkage that connects the left and right front wheels to a vehicle body frame, a lock that locks or unlocks the linkage, a lock controller that controls the lock, a wheel speed sensor that detects a vehicle speed, and a vehicle speed change rate obtainer that obtains a vehicle speed change rate. The lock controller unlocks the linkage via the lock if the linkage is locked by the lock and at least one of the vehicle speed and the vehicle speed change rate satisfies an unlocking condition.

A vehicle steering system has a pitman arm being pivotable about a pitman arm pivot axis in response to pivoting of a steering column, a link pivotally connected to the pitman arm, an idler arm pivotally connected to the link and being pivotable about an idler arm pivot axis, the link extending between the pitman arm and the idler arm, a first tie rod pivotally connected to the pitman arm and extending from the pitman arm in a first direction, and a second tie rod pivotally connected to the idler arm and extending from the idler arm in a second direction, the second direction being opposite the first direction. A vehicle having the vehicle steering system is also described.

A vehicle includes a frame, a plurality of ground-engaging members, a steering assembly for steering the vehicle, an internal combustion engine, and a continuously variable transmission (CVT). An engine air intake system provides air to the engine and includes a first air inlet facing generally forwardly and a first rearwardly-extending conduit portion extending rearwardly from the first air inlet. The first rearwardly-extending conduit portion fluidly communicates with an engine air inlet. A CVT air intake system provides air to the CVT and includes a second air inlet facing generally forwardly and a second rearwardly-extending conduit portion extending rearwardly from the second air inlet. The second rearwardly-extending conduit portion fluidly communicates with a cooling air inlet of the CVT. The engine is disposed at least in part laterally between the first and second rearwardly-extending conduit portions.

A rear axle system keeps rear wheels turning on the same axis when they are fixedly attached to the axles. One embodiment of the present invention fixedly attaches an axle to each rear wheel. Each of the axles extend through a self aligning, pillow block bearing to almost the center of the vehicle. The bearings are mounted to the outer portion of the frame on each side and there is a tube that encases the two axles. The inner diameter of the tube is large enough to allow the two axles to turn with respect to each other but small enough to keep the two axles turning on the same axis. When the vehicle is traveling in a straight line, the tube is turning with the axles. When the vehicle is turning, there is little difference in speed and no requirement for bearings between the axles and the rigid tube.

A vehicle has a driver module and a propulsion module selectively connected to the driver module. The modules are separable from each other as independent units. The driver module has a driver module frame, at least one front wheel operatively connected to the driver module frame, at least one front suspension assembly operatively connecting the at least one front wheel to the driver module frame, and a seat connected to the frame. The propulsion module has a propulsion module frame, at least one rear wheel operatively connected to the propulsion module frame, at least one rear suspension assembly operatively connecting the at least one rear wheel to the propulsion module frame, a motor operatively connected to the at least one rear wheel, and an energy storage device operatively connected to the motor.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.
