  • Publication number: 20230311873
    Abstract: Methods, systems, and apparatuses are provided for a vehicle tethered by a hitch to a trailer. The method includes generating sensor data from one or more sensors that are responsive to forces applied to the hitch by a vehicle mechanically coupled to the hitch; receiving sensor data to compute a direction for the guidance of the trailer; monitoring a set of parameters reflecting forces in a lateral and traverse direction derived from data generated by the sensors wherein the set of parameters include at least one parameter of a magnitude of force, and at least one parameter of the direction of force acting upon the hitch; and calculating at least a rate-of-change of the magnitude of force and direction over time to determine a trajectory for the trailer that enables the trailer to follow the lead vehicle without a tractive effort of the lead vehicle.

  • Patent number: 11001152
    Abstract: Presented are adaptive propulsion assist systems and control logic for manually-powered vehicles, methods for making/using such systems, and intelligent electric scooters with distributed sensing and control-loop feedback for adaptive e-assist operations. A method for regulating a propulsion assist system of a manually-powered vehicle includes a vehicle controller detecting a user contacting the vehicle's handlebar, responsively receiving sensor signals indicative of a user-applied force to the handlebar, and then determining a net user-applied force based on the handlebar force and user-generated forces applied to the scooter deck. The vehicle controller also receives sensor signals indicative of the vehicle's current acceleration, and determines therefrom a pitch angle of the surface on which the vehicle moves.
