    Abstract: A method for fore-aft stabilization of a vehicle for motion in a specified direction over an underlying surface. The vehicle has at least one forward wheel and at least one aft wheel, and the forward wheel is characterized by a force normal to the instantaneous direction of motion of the vehicle. A motor actuator drives each aft wheel, and a controller governs the motor actuator or motor actuators in such a manner as to dynamically stabilize the vehicle, according to a uniform control law, when the forward wheel is in contact with the underlying surface or not. A torque is applied to the aft wheel on the basis of vehicle pitch or the force on the forward wheel normal to the direction of motion. Additionally, a periodic rotational modulation may be applied to the aft wheel, and a stabilizing torque provided based on a detected response, either of vehicle pitch or of normal force on the front wheel. Left and right motor actuators may independently control left and right aft wheels to continue turns as governed by user steering, whether or not forward wheels are in contact with the ground.

    Abstract translation: 一种用于车辆前后稳定的方法，用于在下面的表面上沿指定方向运动。 车辆具有至少一个前轮和至少一个后轮，并且前轮的特征在于垂直于车辆的瞬时运动方向的力。 电动机执行器驱动每个后轮，并且当前轮与下面的表面接触时，控制器以这样的方式控制电动机致动器或电动机致动器，以便根据统一的控制规律动态地稳定车辆。 基于车辆间距或者正向于运动方向的前轮上的力，对后轮施加扭矩。 此外，可以对后轮施加周期性的旋转调制，以及基于检测到的响应提供的稳定转矩，车辆间距或前轮上的法向力。 左右电机执行器可以独立地控制左右后轮继续转动，由用户转向控制，无论前轮是否与地面接触。

    Abstract: A controller and methods for controlling the speed of a vehicle having an electric motorized drive is provided. In one embodiment, a method involves determining a steady state average torque and a torque during acceleration or deceleration of the vehicle traveling over an underlying surface. Speed of the vehicle is controlled based on the steady state average torque, the torque during acceleration or deceleration the measured regeneration current generated by a motorized drive arrangement of the vehicle that applies torque to at least one ground-contacting element of the vehicle for traveling over the underlying surface, weight of the vehicle and payload, the torque applied to the ground-contacting element, acceleration of the vehicle and the speed of the vehicle.
