  • Patent number: 8996254
    Abstract: A vehicle motion control apparatus which is configured to control a motion of a vehicle comprising a plurality of apparatuses, each of which is configured to selectively control a slip angle or a yaw rate, is provided with: a behavior controlling device which is configured to perform behavior control in which a plurality of apparatuses are controlled such that a slip angle and a yaw rate are a set target slip angle and a target yaw rate, respectively; a turning state quantity specifying device which is configured to specify a turning state quantity of the vehicle; and a selecting device which is configured to select at least one of the slip angle and the yaw rate to be prioritized, on the basis of the specified turning state quantity in a case where the behavior control needs to be performed by one of the plurality of apparatuses.

  • Publication number: 20110077823
    Abstract: A steering control device for a vehicle independently performs a steering control of front wheels and rear wheels. A phase control unit performs a control of a steering control unit so as to control a phase difference between a yaw rate and a lateral acceleration at a predetermined position in a vehicle interior. Additionally, a setting unit sets the predetermined position based on a riding position condition of passengers in the vehicle interior. Therefore, it is possible to appropriately control the phase difference between the yaw rate and the lateral acceleration at the predetermined position in the vehicle interior. So, it becomes possible to appropriately ensure a comfort (ride quality) of the passenger at the predetermined position.

  • Patent number: 7809483
    Abstract: A vehicle steering control device capable of executing automatic steering and manual steering includes: an automatic control amount-setting device that sets a target automatic control amount based on information about vehicle behavior and ambient environment; a steering control amount-setting device that sets a target steering amount based on a manual steering amount input by a driver and the set target automatic control amount; and a steering device that steers based on the set target steering amount. When the target automatic control amount contributes more in the setting of the target steering amount than the manual steering amount does, the steering control amount-setting device sets the target steering amount so as to better the responsiveness in the lateral shift of the vehicle relatively to the responsiveness in the turning of the vehicle, in comparison with when the target automatic amount does not contribute more than the manual steering amount.
