  • Device and method for detecting manual guidance of a steering wheel
    Patent number: 10773750
    Abstract: A device (1) and a method for detecting manual guidance of a steering wheel by a driver, have a torque sensor (3) for measuring a steering wheel torque (Ts) of the steering wheel; an angular speed sensor (4) for measuring an angular speed (?c) of a steering wheel column connected to the steering wheel; and a calculation unit (5) for calculating a driver torque (Td) exerted by the driver on the steering wheel as a function of the measured steering wheel torque (Ts) and the measured angular speed (?c) of the steering wheel column, and for filtering the calculated driver torque (Td) to determine a steering angle component (?cT) which is compared with a threshold (?tol) to recognize manual guidance of the steering wheel by the driver.
