  • Steering system
    Patent number: 9024628
    Abstract: A steering system includes a steering shaft an electric motor that assists a steering component; a torque detection device that generates a first detection signal according to a steering torque; and a compensation sensor that generates a second detection signal according to a magnetic flux around the steering shaft and its surrounding structure. In the steering system, an output signal, in which an influence of the magnetic field around the steering shaft and its surrounding structure is reduced, is generated based on a signal correction computing equation based on information on correlation between the first detection signal and the second detection signal. Then, in the steering system, the electric motor is driven based on the output signal.
