Publication number: 20200102006Abstract: A method estimates a track rod force which is exerted, in a power steering system with which a vehicle is equipped, on a track rod belonging to a steering mechanism which connects an actuator to a steered wheel which is orientable in the yaw direction and which bears a tyre of which the tread is in contact with the ground, the value of the estimated track rod force being corrected as a function of the longitudinal speed of the vehicle by a force component that models the release of the elastic torsion of the tyre so as to reduce, the estimated track rod force according to the longitudinal speed of the vehicle, when the vehicle transitions from a park situation in which the longitudinal speed of the vehicle is zero to a drive situation in which the longitudinal speed of the vehicle is non-zero.Type: ApplicationFiled: May 15, 2018Publication date: April 2, 2020Applicant: JTEKT EUROPEInventors: Sébastien BOURDREZ, Pierre DUPRAZ, Serge GAUDIN, Pascal MOULAIRE, Kazusa YAMAMOTO

Publication number: 20200102007Abstract: An electric power steering apparatus having independent turning mechanisms for respective four wheels of a vehicle, has a problem in that, when a turning motor fails, a turning mechanism for a corresponding wheel stops functioning, resulting in reduction in the maneuverability and the stability of the vehicle. Turning motors of turning mechanisms independently disposed for respective four wheels of a vehicle, each have a redundant configuration. Specifically, each turning motor is configured as three-phase duplexing motors having two three-phase windings and two inverters for separately driving the three-phase windings.Type: ApplicationFiled: February 28, 2018Publication date: April 2, 2020Applicant: Mitsubishi Electric CorporationInventor: Satoru AKUTSU
