  • Publication number: 20140117971
    Abstract: A shift sensor includes a movable member, four movable contacts, seven fixed contacts, and two power supply terminals. Each of the movable contacts is fixed to the movable member and pivoted to a position corresponding to a shift position. Each of the fixed contacts outputs a shift signal when it is brought into conduction with a power supply terminal by coming into contact with any of the movable contacts. The fixed contacts are arranged such that the number of shift signals that differ between shift positions is three or more, between the shift positions of P, R, N, D, and B, except for between the D and B positions.

  • Publication number: 20140116033
    Abstract: A wall flow type particulate filter is arranged inside the exhaust passage of an internal combustion engine where combustion is performed under an excess of oxygen. The particulate filter carries a solid acid. The solid acid has a Hammett acidity function smaller than ?0.83 and larger than ?12 in the standard state. To remove the ash from the particulate filter, ash atomization processing for rendering the state of the particulate filter a state where the exhaust gas which flows into the particulate filter is lowered in concentration of oxygen and the particulate filter is raised in temperature is temporarily performed.

    Abstract: In an internal combustion engine, inside an engine exhaust passage, a hydrocarbon feed valve (15) an exhaust purification catalyst (13), and a particulate filter (14) are arranged. If the hydrocarbon feed valve (15) feeds hydrocarbons by a period of within 5 seconds, a reducing intermediate is produced inside the exhaust purification catalyst (13). This reducing intermediate is used for NOx purification processing. When the stored SOx should be released from the exhaust purification catalyst (13), the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) is made rich, the reducing intermediate built up on the exhaust purification catalyst (13) is made to be desorbed in the form of ammonia, and the desorbed ammonia is used to make the exhaust purification catalyst (13) release the stored SOx.

    Abstract: A hook that constitutes a locking device is pushed and rotated in accordance with movement of a striker that moves into a recessed portion of a base plate, and the striker S is sandwiched between the hook and the recessed portion. As the hook rotates, a pole rotates under bias force to a position at which the pole is engaged with the hook, so as to restrict rotation of the hook for returning to the initial position. The hook, when placed in the initial position, is held in a condition in which a corner portion of the hook is pressed under bias force against a stopper face of the pole, such that the hook is inhibited from rotating. The stopper face is curved in the shape of an arc drawn about a first support shaft that supports the pole.

A controlling device controls the hydraulic pressure increasing or decreasing period changing device to change the increasing or decreasing period of the hydraulic pressure corresponding to each of the wheels in contact with a road surface having a high road surface friction coefficient, from that where a left-right braking force difference is not generated, to where the left-right braking force difference is generated by the hydraulic pressure controlling device.

  • Patent number: 8712652
    Abstract: Providing a control device of a hybrid vehicle capable of reducing a rattling noise without changing an engine rotation speed. If the second electric motor torque TM2 is within the rattling noise occurrence region G, the engine rotation fluctuation suppression control (at least one of the EGR amount suppression control, the self-EGR amount suppression control, the lean-burn control, and the ignition delay control) is provided to suppress the engine rotation fluctuations as compared to during normal running while the second electric motor torque TM2 is out of the rattling noise occurrence region G and, therefore, the engine rotation fluctuations can be suppressed to reduce the a rattling noise without changing an engine rotation speed NE. Thus, the rattling noise can be reduced without giving an uncomfortable feeling to a user due to a change in the engine rotation speed NE.

  • Patent number: 8707680
    Abstract: In an internal combustion engine, inside of an engine exhaust passage, air-fuel ratio sensors each of which has a solid electrolyte, electrodes which respectively cover the two side surfaces of the solid electrolyte, and a diffusion resistance layer which covers one of electrodes are arranged. In operation, the greater the amounts of deposition of sulfur ingredients at the air-fuel ratio sensors, the smaller the amounts of change of the air-fuel ratios detected by the air-fuel ratio sensor and the longer the time period of change of the air-fuel ratios. The amounts of sulfur poisoning of the air-fuel ratio sensors are detected from the changes of the air-fuel ratios detected by the air-fuel ratio sensors.

  • Patent number: 8712619
    Abstract: A vehicle is equipped with a battery configured so as to be rechargeable, a motor generator configured so as to generate the driving force of the vehicle by use of electric power stored in the battery, a switch configured so as to switch between generation of a command for extending the use period of the battery and stop of generation of the command, and an ECU for controlling the state of charge of the battery. The ECU sets the control range of SOC of the battery. When the switch stops generation of the command, the ECU sets the control range to a first range. Meanwhile, when a command is generated by the switch, the ECU sets the control range to a second range narrower than the first range.

  • Patent number: 8708113
    Abstract: A brake system includes a pad having a frictional surface, and a disc having a frictional surface sliding on the frictional surface. The frictional surface includes hard particles supported elastically and a plurality of protrusions arranged along a direction in which the frictional surface slides on the frictional surface, and when the frictional surface slides on the frictional surface, hard particles abut respective protrusions continuously while being displaced in the direction perpendicular to the frictional surface. Thus, wear resistance can be improved Since only the vicinities of the peaks of the hard particles and the vicinities of the peaks of the protrusions abut, the hard particles do not follow irregularities of the frictional surface, and thereby the hard particles and the protrusions repeat point contact. Thus, since the distance between the hard particles and the protrusions is stabilized and the adhesion frictional force is stabilized, a stable frictional force can be obtained.
