Patent number: 10676074Abstract: 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.Type: GrantFiled: May 15, 2019Date of Patent: June 9, 2020Assignees: AUTOLIV NISSIN BRAKE SYSTEMS JAPAN CO., LTD., HONDA MOTOR CO., LTD.Inventors: Kazuaki Miyata, Takeshi Kojima, Tomoyuki Futamura

Patent number: 9158739Abstract: In a pendular motion determination unit of a motion stabilizer for a tractor, a parameter computation unit computes a determination parameter PA indicative of a quantity of change in an actual yaw rate Y, a threshold value setting unit computes a threshold value PAth for the parameter PA, and a determination unit determines that a pendular motion caused by swaying motion of a trailer is imparted, if the parameter PA is greater than the threshold value PAth. Based upon at least one of a value related to the actual yaw rate Y and a value related to the standard yaw rate Ys, an evaluation value computation unit computes a steering-back maneuver evaluation value TS (indicative of a possibility of making periodical steering-back maneuvers), based upon which at least one of the threshold value PAth and the parameter PA is changed.Type: GrantFiled: March 27, 2013Date of Patent: October 13, 2015Assignees: NISSIN KOGYO CO., LTD., HONDA MOTOR CO., LTD.Inventors: Kazuaki Miyata, Takeshi Kojima, Tomoyuki Futamura
