  • Patent number: 10899381
    Abstract: A steering device is provided to perform a safe transition from an automatic driving mode to a manual driving mode when necessary. When it is determined necessary to transition from the automatic driving mode to the manual driving mode during the automatic driving mode, a transition period before an end time point of the automatic driving mode is set, a driving operation reliability indicative of whether or not it is possible to perform the transition is determined, and the transition when it is determined that it is possible to perform the transition to the manual driving mode during the automatic driving mode. Consequently, the transition can be controlled so that transition is not performed instantly, such as, for example, in a case where a driver is not driving during the automatic driving mode and is not accustomed to manual driving.

  • Patent number: 9487230
    Abstract: For compensation for loss of a steering assist force due to friction of a steering mechanism, when calculating a friction correction value for the compensation, in an electronic control unit 6, a static friction and a kinetic friction are distinguished, and the calculation is made by combining the static friction correction value Sf and the kinetic friction correction value Kf according to each friction. It is therefore possible to make a proper friction loss compensation according to type of the friction.
