A control system for a tiltable vehicle may include a motor controller configured to respond to backward or reverse operation of the vehicle by hindering a responsiveness of the control system (e.g., proportionally) and/or eventually disengaging a drive motor of the vehicle. Accordingly, a user may intuitively and safely dismount the vehicle by selectively commanding reverse operation. In some examples, the backward direction may be user-defined.

A method, system and apparatus for carrying a user including a board for supporting the user, a ground-contacting member coupled with the board, a motorized drive assembly coupled with the ground-contacting member and one or more sensors coupled with the drive assembly. In operation, the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors. As a result, the system is able to maintain a desired velocity when ascending, descending or traversing uneven ground without the need for excessive and sometimes impossible tilting of the board.

A robotic motorcycle may include a chassis, driven wheel assemblies, and a control loop stabilizer. The driven wheel assemblies may each include a wheel and a bevel gear. The wheel may be mounted to an axle for rotation about a drive axis and steering about a substantially vertical steering axis. A steer shaft may connect the axle to a steer assembly that controls rotation of the steer shaft about the steering axis to steer the wheel. A drive shaft may be coupled to a drive assembly that controls rotation of the drive shaft about the steering axis. The bevel gear may couple the other end of the drive shaft to the axle so that rotation of the drive shaft about the steering axis controls rotation of the wheel about the drive axis. The control loop stabilizer may determine parameters for the drive and steer assemblies to balance the motorcycle.

Vehicles are disclosed that are configured to carry loads in a stabilized manner, such that the load is maintained in a substantially constant position or orientation relative to a predetermined reference point or frame even as the vehicle moves. A stabilization controller in such a vehicle receives information about movement of the vehicle relative to the reference point or plane from one or more sensors on the vehicle, and uses the information to control one or more movable objects by which the load is secured to the vehicle so as to maintain a relatively constant relationship between the load and the reference point or plane.

A vehicle control system includes a powertrain electronic control unit and an electronic stability control unit that is connected to the powertrain electronic control unit via a vehicle communication bus. The vehicle powertrain includes a wheel, a wheel speed sensor that is configured to detect a speed of the wheel, an electric motor that is configured to drive the wheel, and an electric motor speed sensor that is configured to detect the speed of the electric motor. If the wheel speed sensor is operating normally, the electronic stability control unit controls the vehicle based on an output of the wheel speed sensor. However, if the wheel speed sensor is not operating normally, the electronic stability control unit controls the vehicle based on an output of the electric motor speed sensor.

A vehicle control system includes a powertrain electronic control unit and an electronic stability control unit that is connected to the powertrain electronic control unit via a vehicle communication bus. The vehicle powertrain includes a wheel, a wheel speed sensor that is configured to detect a speed of the wheel, an electric motor that is configured to drive the wheel, and an electric motor speed sensor that is configured to detect the speed of the electric motor. If the vehicle is not traveling at low speeds (for example, less than 2 kilometers per hour), the electronic stability control unit controls the vehicle based on an output of the wheel speed sensor. However, if the vehicle is traveling at low speeds, the electronic stability control unit controls the vehicle based on an output of the electric motor speed sensor.

The present disclosure relates to a novel portable electric vehicle, which comprises two front-rear folding mechanisms, a left-right folding mechanism, and an operating mechanism, wherein the two front-rear folding mechanisms for supporting a driver are arranged respectively on the left side and the right side of the bottom of the electric vehicle, the rear ends of the front-rear folding mechanisms are both provided with driving wheel mechanisms, and the front ends of the front-rear folding mechanisms are both provided with rotating wheel mechanisms; two ends of the left-right folding mechanism for driving the two front-rear folding mechanisms to get close to each other are connected respectively to the two front-rear folding mechanisms; and the operating mechanism for controlling the running of the electric vehicle is mounted on the left-right folding mechanism. The present disclosure also relates to a method for controlling the drive of the novel portal electric vehicle, which utilizes an Arduino circuit board to control the running of the electric vehicle. The novel portable electric vehicle has the advantages of good driving experience, small size, light weight, convenience in folding and easiness in operation, and belongs to the technical field of electric vehicles.

A self-propelled, one-wheeled vehicle may include a suspension system configured to provide arcuate, generally vertical motion of a board relative to an axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems may include a shock absorber and a swingarm that couple the wheel assembly to the board.

An auxiliary transport vehicle according to the disclosure comprises a drive unit and an attachment that is placed thereon, wherein the drive unit comprises just two wheels with a common axis of rotation and each with an electric drive, an electronic control device and an electrical energy storage device, and wherein the control device is embodied for actuating the drives in such a way that the auxiliary transport vehicle is kept in an upright position, and for autonomously driving the auxiliary transport vehicle to a specifiable destination and for following an external control device. The disclosure also concerns an auxiliary transport system and a method for operating an auxiliary transport vehicle.

A portable two-wheeled self-balancing personal transport vehicle comprises a single support platform having first and second foot placement sections, one or more inertial sensors operable to provide pitch data for the platform. The first foot placement section and the second foot placement section are associated with a first wheel and a second wheel respectively controlled by a first and a second drive motor. At least one load sensor provides first load data for the first foot placement section and at least one load sensor provides second load data for the second foot placement section. Control circuitry is connected to the first and second drive motors, and operable to transmit to the first and second drive motors balancing signals for self-balancing the support platform housing in response to the pitch data, as well as one or more steering torque signals in response to the first and second load data.
