Stowable Steering Wheel Obstruction Detection

The patent implements feedback control by using sensors to detect the steering column position and comparing it against target positions. The controller receives feedback signals from the sensor, determines position discrepancies, and adjusts the motor actuator accordingly to achieve precise positioning. This closed-loop feedback mechanism resolves the contradiction by enabling precise control of the retractable steering wheel, ensuring safety while maintaining cabin space benefits.

The patent replaces traditional mechanical position sensing with electronic sensors and digital control systems. Instead of relying solely on mechanical linkages and physical stops, the system uses sensors to detect position, processes information through a controller, and actuates the steering column using motor-driven mechanisms. This substitution enables more precise control and adds obstruction detection capabilities, resolving the reliability issue while maintaining the space-saving retractable design.

The patent implements preliminary action by detecting obstructions before the steering column completes its movement cycle. The sensor continuously monitors the path of the steering column during retraction and extension, and the controller identifies potential obstructions in advance. When an obstruction is detected, the system stops the movement before collision occurs, preventing harmful effects while maintaining the moveable design that provides cabin space.

The sensor provides continuous feedback about the steering column's position and any obstructions in its path during movement. The controller processes this feedback in real-time and adjusts the motor actuator accordingly, stopping movement when obstructions are detected. This feedback mechanism enables the system to maintain safety during the space-saving retraction operation by continuously monitoring and responding to potential hazards.
