  • STEERING HOLDING DETERMINATION DEVICE, STEERING CONTROL DEVICE, AND STEERING DEVICE
    Publication number: 20220281520
    Abstract: A steering holding determination device configured to determine whether a driver holds a steering member, the steering holding determination device including: a predicted value calculation unit configured to calculate a predicted value of at least one of one or more state quantities related to steering of the steering member and one or more state quantities related to turning of a wheel; and a steering holding determination unit configured to determine whether the driver holds the steering member with reference to the predicted value calculated by the predicted value calculation unit and a variance of the predicted value.
    Type: Application

  • STEERING HOLDING DETERMINATION DEVICE, STEERING CONTROL DEVICE, AND STEERING DEVICE
    Publication number: 20220274643
    Abstract: A steering holding determination device configured to determine whether a driver holds a steering member, the steering holding determination device including: a predicted value calculation unit configured to sequentially calculate a predicted value of a state quantity with reference to a steering torque and an actual measured value of the state quantity, the state quantity being related to a turning angle of a wheel; and a steering holding determination unit configured to determine whether the driver holds the steering member with reference to the predicted value calculated by the predicted value calculation unit and an actual measured value corresponding to the predicted value.
