  • Publication number: 20120316733
    Abstract: A vehicle turning control device of the present invention includes: a correcting section that decides a correction amount for correcting a first standard yaw rate in a direction of increase, and calculates a second standard yaw rate from the first standard yaw rate in accordance with this correction amount; a braking force control amount operating section that calculates a yaw rate deviation between the second standard yaw rate and the actual detected yaw rate, and decides a braking force control amount in a direction which cancels out the yaw rate deviation; and a braking control device that controls the braking force based on the braking force control amount. The correcting section is provided with a plurality of correction regulating sections that, when they determine that a vehicle is in a predetermined running state, decrease the correction amount.

  • Publication number: 20120212043
    Abstract: A brake fluid pressure control apparatus for a vehicle includes a parameter calculation unit configured to calculate a rollover detection parameter; and a steering maneuver determination unit configured to determine whether an abrupt steering maneuver is made. The parameter calculation unit is configured to calculate a first composition roll angle as the rollover detection parameter, by combining at a predetermined weight assignment ratio a first roll angle equivalent to an actual roll angle with a second roll angle obtained using a parameter which changes with a phase earlier than the first roll angle, and to calculate the first composition roll angle by changing the weight assignment ratio such that a weight of the second roll angle is higher when the steering maneuver determination unit determines that an abrupt steering maneuver is made than when the steering maneuver determination unit determines that the abrupt steering maneuver is not made.

  • Patent number: 8180543
    Abstract: A movement stabilizing control ECU 25 includes a differential unit 25a, a cycle calculation unit 25b, a time constant/gain setting portion 25c, a first-order lag processing unit 25d, a pendulum movement detection unit 25e, a control amount calculation portion 25f and a control amount output unit 25g. The time constant/gain setting portion 25c sets a time constant ? and a gain K used at the time of subjecting a yaw acceleration ?? which is a time-differential value of a yaw rate ? to the first-order lag processing at the first-order lag processing unit 25d, with reference to a function or data of a look-up table, for example, depending on the cycle or the frequency of the yaw acceleration ?? due to the pendulum movement.
