Publication number: 20160297439Abstract: An apparatus as an aspect of the invention acquires a vehicle motion index value, a driving state index value of a driver, a driving characteristic value that is estimated based on the vehicle motion index value and the driving state index value, and a vehicle motion target value and a driving state target value that are determined regardless of the driver's driving. Using these values, the apparatus determines a target value of a steering assist torque and a target value of a difference in braking/driving force between right and left wheels that converge at least one of a difference between the vehicle motion target value and the vehicle motion index value and a difference between the driving state target value and the driving state index value. The apparatus controls the steering assist torque and the difference in braking/driving force between the right and left wheels to their respective target values.Type: ApplicationFiled: April 5, 2016Publication date: October 13, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shintaro INOUE, Hideo INOUE, Yutaka HIRANO, Pongsathorn RAKSINCHAROENSAK

Publication number: 20160297478Abstract: In a driving support system of a vehicle, there is provided a structure that, even during operating a control based on a machine input, a driver's sense of incongruity can be reduced as much as possible and/or the steering of the driver be can reflected. The vehicle is equipped with a steering assist mechanism and a braking-driving force distribution mechanism of right and left wheels. In operations of the inventive device, a steering assist torque, applied by the steering assist mechanism, is controlled to a target value determined with reference to a target steering torque to achieve the target route, determined without depending on steering of a driver, and a driver's steering torque; and a braking-driving force difference between the right and left wheels is controlled to a target value based on a steering angle of the driver.Type: ApplicationFiled: March 21, 2016Publication date: October 13, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shintaro INOUE, Hideo INOUE, Yutaka HIRANO, Pongsathorn RAKSINCHAROENSAK

Publication number: 20160236679Abstract: There is provided a structure in a driving support system of a vehicle equipped with a steering assist mechanism and a torque vectoring mechanism of right and left wheels, the system capable of reducing an occurrence of a driver's sense of incongruity as much as possible also during the operation of a control based on a machine input and reflecting a driver's steering in the control. The inventive device comprises a steering assist torque controller which controls a steering assist torque given by the steering assist mechanism, a right and left braking-driving force difference controller which controls the braking-driving force difference between the right and left wheels given by the torque vectoring mechanism and a control target value determiner which determines the target values of the steering assist torque and braking-driving force difference for driving support control, based on the steering torque by the driver.Type: ApplicationFiled: February 17, 2016Publication date: August 18, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shintaro INOUE, Hideo INOUE, Yutaka HIRANO, Pongsathorn RAKSINCHAROENSAK

Publication number: 20150336587Abstract: A driving assist device 1 includes: an information acquisition unit 20 that detects a driving operation of a driver for the vehicle; a driving skill evaluation unit 24 that evaluates a driving skill of the driver on the basis of a history of the driving operation of the driver; and a driving assist control unit 28 that performs the driving assist control for the vehicle on the basis of the traveling state of the vehicle and the target traveling state. When the information acquisition unit 20 detects the driving operation of the driver during the driving assist control, the driving assist control unit 28 limits the amount of driving assist control for the vehicle according to the driving skill of the driver evaluated and reflects the driving operation amount of the driver in traveling control for the vehicle.Type: ApplicationFiled: May 18, 2015Publication date: November 26, 2015Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, THE UNIVERSITY OF TOKYO, National University Corporation Tokyo University of Agriculture and TechnologyInventors: Hideo INOUE, Shintaro INOUE, Masahiro MIO, Shingo SAKAIDA, Tsukasa SHIMIZU, Masayuki OKUWA, Minoru KAMATA, Takuma ITO, Pongsathorn RAKSINCHAROENSAK, Masao NAGAI

Patent number: 8090492Abstract: The apparatus comprises a measured signal detector 11, a vehicle parameter obtainer 12, a sideslip angle temporary estimator 13, a sideslip angle differential corresponding value computer 14 and a sideslip angle real estimator 15. A sideslip angle temporary estimate value is computed from one or plural vehicle parameters including at least the mass. A sideslip angle differential corresponding value is computed from a measured signal and the vehicle parameters including no mass. A sideslip angle is derived from the sideslip angle temporary estimate value and the sideslip angle differential corresponding value. A sideslip can be detected without a steering angle detection mechanism.Type: GrantFiled: February 7, 2007Date of Patent: January 3, 2012Assignee: National University Corporation Tokyo University of Agriculture and TechnologyInventors: Masao Nagai, Yohei Michitsuji, Pongsathorn Raksincharoensak

Patent number: 7668635Abstract: A front wheel steering control device improves the handling and stability of a vehicle with respect to the steering wheel angles. The front wheel steering control device includes an input device for obtaining the steering wheel angle and the vehicle velocity, a first computing device for computing a yaw-rate for the vehicle which maintains the vehicle gravity center point sideslip angle at zero based on the steering wheel angle and the vehicle velocity that are obtained by the input device, a second computing device for computing a target front wheel actual steering angle for realizing the yaw-rate calculated by the first computing device, a control device for performing a steering control of the vehicle based on the target front wheel actual steering angle calculated by the second computing device. The ideal determination of the vehicle steering gear ratio and the derivative steering gain are relatively easy.Type: GrantFiled: May 18, 2005Date of Patent: February 23, 2010Assignee: National University Corporation Tokyo University of Agriculture and TechnologyInventors: Pongsathorn Raksincharoensak, Masao Nagai
