An electric vehicle includes a lateral self-stabilization system and may further include a fore-aft self-stabilization system. The lateral self-stabilization system may include a controller configured to cause an actuator to laterally tilt a frame of the vehicle based on sensed information relating to an orientation of the vehicle, or portion thereof, about a roll axis. The frame of the vehicle may include any suitable structure configured to be laterally tilted by the actuator relative to an axle of the vehicle. The fore-aft stabilization system may include a motor controller configured to drive a motor of the vehicle based on sensed information relating to a pitch angle of the vehicle. In some examples, the vehicle is a robotic vehicle.

When an electric vehicle is traveling downhill, experiencing regenerative braking, or otherwise forcing the vehicle motor to turn faster than the commanded motor torque, the vehicle motor produces electrical energy that can be used to recharge a vehicle battery. However, if the vehicle battery is already nearly or fully charged, the excess electrical energy produced may damage the battery. Control systems described herein may reduce and/or dispose of the excess energy by manipulating the motor flux (i.e., direct) current and quadrature current independently.

The present invention provides a motorized skate having a balance control system adapted to maintain fore-and-aft balance of a platform of the skate about a wheel arrangement. The wheel arrangement defines a pivot point for the platform. A motor arrangement is adapted to drive the wheel arrangement so as to allow for the balance control system to maintain fore-and-aft balancing of the platform about the wheel arrangement.

A pair of foot lift attachments for attachment to single-wheel motorized electric skateboards, and combinations thereof. The foot lift attachments include a right foot lift attachment and a left foot lift attachment, each having a first concave curved outer facing side wall configured to be engaged on a curved support surface of either of a fender covering the single wheel, or a curved support surface of a mounting bracket secured at each side of the opening for the single wheel, and each having a convex curved top end wall with a concave curved underside configured to laterally receive and overlap the medial side and a top portion of the skateboard rider's foot and footwear worn on the foot to enable the rider to lift the skateboard off the ground with their feet and perform freestyle skateboarding maneuvers and aerial moves and jumps.

A self-balancing vehicle includes two vehicle bodies, respectively including a carrier assembly, a moving mechanism, a control assembly, and a power supply device coupled to the control assembly. The carrier assembly includes a frame and a foot platform coupled to the frame to form a cavity. The frame recess towards the foot platform defining a groove. The moving mechanism includes a wheel disposed on the groove side of the frame and a driving member. Part of the wheel is accommodated in the groove. The driving member drive the wheel to rotate relative to the frame. The control assembly includes a posture sensor detecting a tilt angle of the frame with respect to the vertical direction and a controller controlling a rotation speed of the driving member. At least one of the power supply device and the controller is accommodated in the cavity.
