Patent number: 11618297Abstract: A method of operating an adjustable roll stabilizer for a motor vehicle. The stabilizer has an actuator which can be rotated through a system angle about a rotational axis to apply a system torque and rotate two stabilizer sections relative to one another about the axis. The stabilizer sections are coupled at a radial distance from the axis to a respective wheel suspension, and depending on the system angle and under the external influence of movements of the wheel suspensions, twist relative to one another through a stabilizer angle. In the context of a perturbation magnitude regulation, the actuator is controlled based on the stabilizer angle determined from height levels of the wheels, by virtue of a stored relationship for the roll stabilizer and/or motor vehicle. The plausibility of the stored relationship between the wheel height levels and the stabilizer angle is checked by a model calculation.Type: GrantFiled: August 26, 2020Date of Patent: April 4, 2023Assignee: ZF Friedrichshafen AGInventors: Philip Niemeyer, Stefan Lekon

Patent number: 11097588Abstract: An air suspension system which includes the ability to adjust the working air volume, pressure, and spring rate of one or more air springs to reduce or eliminate various types of vehicle oscillations. Switchable or variable volume air spring assemblies have the ability to change air spring volumes, which results in changes in air spring rates, and therefore changes in normal loads applied to each wheel. Changes in wheel normal loads change wheel traction (slip) and vehicle dynamics (pitch, roll, yaw displacement, rate and acceleration). The spring rate of one or more of the air spring assemblies is adjusted automatically when a vehicle oscillation is detected. This vehicle oscillation is calculated from the raw vehicle signals, or another vehicle module may detect the oscillation and send a command to the air suspension module to change the spring rates. This changes the natural frequency of the vehicle, dampening the oscillation.Type: GrantFiled: November 26, 2018Date of Patent: August 24, 2021Assignee: Continental Automotive Systems, Inc.Inventors: Matthew Conrad Tuhro, Daniel Gregory Goodrich, Patrick Alan Crane

Patent number: 10220840Abstract: Disclosed herein are a vehicle configured to prevent a collision and a control method thereof. The vehicle includes a chassis; a steering unit configured to change a direction of the chassis; a brake unit configured to adjust a braking force of the chassis; a detector configured to detect movement information of the chassis; and a controller configured to confirm a variation rate of movement of the chassis based on the detected movement information and configured to automatically control an operation of the steering unit and the brake unit when the confirmed variation rate is out of a reference range. When a collision occurs, the vehicle may automatically perform at least one of steering control, side braking control, or a damping control, and thus a secondary collision may be prevented, the incidence of additional injury may be reduced, the speed of the vehicle may be stably reduced or stopped, and the vehicle may be moved to a safe lane so that a stabilization time of the vehicle may be reduced.Type: GrantFiled: April 19, 2016Date of Patent: March 5, 2019Assignee: Hyundai Motor CompanyInventors: Youn Seok Choi, Jee Yoon Suh

Patent number: 10220838Abstract: Disclosed is a vehicle control device which is applied to a vehicle equipped with an engine (10) and an engine torque adjustment mechanism for adjusting an engine torque. The control device comprises a PCM (50) configured, upon satisfaction of a condition that the vehicle is traveling and a steering angle-related value relevant to a steering angle of a steering device is increasing, to control the engine torque adjustment mechanism to reduce the engine torque, so as to execute a vehicle attitude control for generating vehicle deceleration. The PCM (50) is configured, upon satisfaction of a vehicle attitude control-terminating condition for terminating the vehicle attitude control, to control the engine torque adjustment mechanism to restore the engine torque to an original level of torque before the execution of the vehicle attitude control.Type: GrantFiled: December 22, 2016Date of Patent: March 5, 2019Assignee: MAZDA MOTOR CORPORATIONInventors: Keiichi Hiwatashi, Daisuke Umetsu, Osamu Sunahara, Koichi Kimoto, Yasunori Takahara, Daisaku Ogawa, Chikako Ohisa

Patent number: 9809079Abstract: In a suspension controlling apparatus for a vehicle including a suspension whose damping force is variably settable and a control unit capable of controlling the damping force of the suspension, for appropriately obtaining a pitch behavior. When a vibration state of a vehicle in a vertical direction exceeds a given vibration state, a control unit controls damping force of suspensions on the basis of a target damping force in order to execute a skyhook control. However, when acceleration in a forward and rearward direction of the vehicle is outside a given range, a decision condition for the given vibration state is changed to a condition on the side on which the skyhook controlling damping force control of the suspensions is less likely to be started.Type: GrantFiled: March 15, 2016Date of Patent: November 7, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Yoshiaki Nedachi, Jun Ishikawa, Hiroki Yoshino

Patent number: 9783229Abstract: A control system calculates inputs to a control target that has m inputs and n outputs (m=n, each of m and n is a natural number that is more than one), while designating a plurality of combinations of the inputs and the outputs. A feedback controller calculates, with respect to each designated combination, a control input to a non-interference controller based on a difference between a target value and a current value of the control quantity to make the current value follow the target value. The non-interference controller executes, with respect to each designated combination, a non-interference control to reduce influence due to mutual interference between n control quantities. This reduces the number of combinations of the inputs and the outputs, the combinations whose mutual interference needs considering; thereby, the non-interference control may be easily achieved.Type: GrantFiled: August 27, 2015Date of Patent: October 10, 2017Assignees: DENSO CORPORATION, NATIONAL UNIVERSITY CORPORATION NAGOYA INSTITUTE OF TECHNOLOGYInventors: Yasuhiko Mukai, Yoshifumi Morita, Hiroyuki Ukai, Makoto Iwasaki, Takeshi Wada
