Dismount controls for one-wheeled vehicle
First Claim
Patent Images
1. A self-balancing electric vehicle comprising:
- one or more wheels having a common axis of rotation;
a board having a first end and a second end, wherein the board is tiltable about the axis of the one or more wheels;
an electric hub motor configured to drive the one or more wheels;
a motor controller configured to receive orientation information indicating an orientation of the board and to cause the hub motor to propel the board based on the orientation information, wherein the motor controller includes processing logic configured to;
receive direction information indicating a direction in which the hub motor is being commanded to propel the board;
in response to the direction information indicating a first direction, hinder a responsiveness of the motor controller to the orientation information by automatically adjusting a first parameter of the motor controller; and
in response to the first parameter reaching a first threshold, turning the hub motor off.

Abstract
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.

14. A control system for an electric vehicle, the control system comprising:
-
a hub motor configured to be coupled to a wheel of a vehicle; a motor controller configured to receive orientation information indicating an orientation of a tiltable portion of the vehicle and to cause the hub motor to propel the vehicle based on the orientation information, wherein the motor controller includes processing logic configured to; receive direction information indicating a direction in which the hub motor is being commanded to propel the vehicle; in response to the direction information indicating a first direction, hinder a responsiveness of the motor controller to the orientation information by automatically adjusting a first parameter of the motor controller; and in response to the first parameter reaching a first threshold, turning the hub motor off. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
