    摘要: 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.

    摘要: A highway grade crossing gate mechanism having a smart cam system capable of measuring a parameter of the gate mechanism in real time is provided. The gate mechanism includes a DC motor, a cam system, and a controller. The DC motor is coupled to a main shaft for driving a gate arm between a vertical position and a vertical position. The cam system includes manually adjustable cams coupled to the main shaft that move contacts to open or close at some preset angular rotation in order to set operational features of a crossing gate. An internal sensing device is disposed internal to the cam system measuring a parameter of the gate mechanism in real time. A controller controls the motor and receives and stores the parameter. The parameter may be transmitted to an external network giving accurate feedback of the state of the gate mechanism in real time.

    摘要: In a force sensor, a cylindrical movable body can be moved with respect to a cylindrical main body. A strain body is fixed to the main body and the movable body, and can be deformed in accordance with the movement of the movable body. Strain sensors are provided on the strain body. At least three circular openings are provided in the circumferential surface of the movable body at equal intervals. Stoppers are respectively arranged inside the openings, and each of which includes a first side surface having a first outer diameter smaller than an inner diameter of the opening, and a second side surface having a second outer diameter smaller than the first outer diameter. Fixing members fix the stoppers to the main body.
