Methods and apparatus to control a torque threshold for hands on/off detection are disclosed. An example steering system includes a steering wheel, a steering shaft operatively coupled to the steering wheel, a rack operatively coupled to the steering shaft, a translational movement of the rack to pivot wheels of a vehicle, a torque sensor operatively coupled to the steering shaft, the torque sensor to measure a torque associated with the steering shaft, an autonomous steering control system to adjust a torque threshold in response to a velocity of the rack satisfying a velocity threshold, and detect a hands off condition in response to the torque satisfying the torque threshold.
