    Abstract: The present disclosure provides an exhaust gas purification catalyst with increased exhaust gas purification performance. The exhaust gas purification catalyst has a porous support, catalyst metal particles supported in the pores of the porous support, and zirconium dioxide particles supported in the pores of the porous support. The zirconium dioxide particles are supported in a uniformly dispersed manner in the pores, as monoclinic crystals or a mixture of monoclinic crystals and tetragonal crystals, the phrase “supported in a uniformly dispersed manner” meaning that when the exhaust gas purification catalyst is measured with an electron beam microanalyzer, the proportion of the abundance ratio of zirconium in a surface region up to a depth of 1.5 ?m from the exhaust gas purification catalyst surface with respect to the abundance ratio of zirconium in the region inward from that surface region of the exhaust gas purification catalyst, is 95 to 105 mol %.

  • Publication number: 20230365187
    Abstract: A vehicle control device includes: dual-system control circuits that control power supply to dual-system winding sets of a motor; and dual-system rotation detection circuits. The control circuits calculate an absolute rotation angle of the motor, and, when a power source is turned off, store an absolute rotation angle of the motor at that time. The control circuits start when the power source is turned on and the absolute value of a difference between an absolute rotation angle that was stored when the power source was turned off last time and an absolute rotation angle that is calculated when the power source is turned on this time is equal to or smaller than a given threshold value, regardless of whether an abnormality has occurred in one of the dual-system rotation detection circuits or an abnormality of the dual-system rotation detection circuits is not determinable.
