  • Publication number: 20200215419
    Abstract: An electric skateboard with a hands free control mechanism includes weight sensors embedded in the front and rear truck base plates to measure both the total weight of the rider as well as their weight distribution on the deck. An advanced skate control circuit uses these weight signals from the base plate to control the motor power, and includes the ability to detect when the rider is kicking the board. During these kicking events, the skate control algorithm changes to a mode which minimises any rapid changes to the skateboard velocity so that the rider will remain stable with just one foot on the deck.
