US 2024/0309692 A1 · SYSTEM AND METHOD OF COMPENSATING FOR DOOR OPERATING FORCE ON INCLINED ROAD

Abstract

A method of compensating for the door operating force on the inclined road surface includes a signal input operation of inputting a sensor signals required for determining the compensating of the operating force of the door to the controller, a stop determination operation of determining, by the controller, whether the vehicle is stopping, a gravitational force determination operation of determining, by the controller, the gravitational forces acting in the transverse direction of the door with the input sensor signals, a compensating torque determination operation of determining, by the controller, the compensating torques to be output from the actuator to offset the gravitational forces, and an operating force compensation operation of compensating for, by the controller, the operating force when the door is opened or closed with the compensating forces.

Dependent claims

A system of compensating for an operating force of a door on an inclined road surface, the system comprising:

the door opened or closed by rotating about a rotation shaft of a body of a vehicle;
an actuator coupled to the door and configured to operate the door with compensating torques for offsetting gravitational forces acting on the door by a weight of the door and gravity;
and
a controller electrically connected to the actuator and configured to determine the gravitational forces acting on the door, determine the compensating torques to offset the gravitational forces, and compensate for the operating force of the door in response that the door is opened in a state in which the vehicle has stopped on the inclined road surface.
