In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.
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.
B60L 15/20 - Methods, circuits or devices for controlling the propulsion of electrically-propelled vehicles, e.g. their traction-motor speed, to achieve a desired performanceAdaptation of control equipment on electrically-propelled vehicles for remote actuation from a stationary place, from alternative parts of the vehicle or from alternative vehicles of the same vehicle train for control of the vehicle or its driving motor to achieve a desired performance, e.g. speed, torque, programmed variation of speed
