Abstract:
A hand cart capable of satisfying walking stabilization and facilitation of carrying articles according to a movement mode includes a control section operable, based on a rotational angle of a wheel section, to calculate a movement distance and a traveling direction, and, according to the traveling direction and the inclination angle, to execute an assist control of causing a wheel driving section to generate a driving torque for assist force or braking torque for braking force, wherein the control section is operable, based on a movement distance and the inclination angle, to calculate an angular change rate of the inclination angle, and, when a contact with a grip member is detected, and the angular change rate is equal to or less than a given threshold, to execute the assist control.
