Claim 18:
19. A method to control an artificial orthotic or prosthetic knee joint, the method comprising:
providing at least one sensor, a below-knee component positioned on the orthotic or prosthetic knee joint, and a resistance device, the below-knee component including a sole member, the at least one sensor including an inertial sensor and an acceleration sensor;
determining sensor data via the at least one sensor during use of the orthotic or prosthetic knee joint;
changing a flexion resistance applied by the resistance device using the sensor data;
determining a linear acceleration at a level of the sole member with the sensor data;
reducing the flexion resistance if the linear acceleration is zero in a horizontal direction;
determining an absolute angle of the below-knee component in order to detect a terminal stance phase; and
reducing the flexion resistance if a predefined limit value for the absolute angle of the below-knee component is exceeded such that the below-knee component has a forward inclination.
