Abstract
An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a rider position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is not required. Rider weight activates the motors.
