    Abstract: In a vehicle automatic transmission having structure in which an output-side rotating element is provided between a speed increasing-side rotating element that is connected to an engine via input clutch and increased rotation speed during downshift into a predetermined speed, and a speed reducing-side rotating element that is reduced in rotation speed by a second engagement apparatus being engaged during the downshift, in an alignment graph, the first engagement apparatus is engaged when, or after, the second engagement apparatus is engaged at the time of the downshift into the predetermined speed. As a result, the rotation speed of the speed reducing-side rotating element is reduced first by the engagement of the second engagement apparatus, which causes driving force to act on the output-side rotating element in a direction that reduces the rotating speed thereof. As a result, forward driving force is prevented from being generated by the output-side rotating element.

    Abstract: A PCV valve that ventilates a crankcase is provided. A three-way catalyst and a NOx storage/reduction catalyst are provided in an exhaust passage. An electronic control unit performs a stoichiometric control and a lean control. When a crankcase ventilation request is issued, a relationship between a ventilation amount of ventilation achieved by the PCV valve and a fuel consumption resulting from the ventilation is calculated. Furthermore, an operational condition under which the ventilation amount meets a required ventilation amount and the fuel consumption is minimized is calculated. The operational condition is calculated so that a constant engine torque is maintained and the air-fuel ratio falls within a range that ensures purification.

    Abstract: A device includes a first unit that calculates a prediction error range of a predicted arrival time in a first route to a destination, a second unit that calculates a prediction error range of a predicted arrival time in a second route different from the first route at a point where the first route and the second route are branched, and an output unit that outputs at least one of the prediction error range of the first route or the prediction error range of the second route. At least one of the first unit or the second unit calculates the prediction error range based on information having correlation with the prediction error range at the point, and the output unit performs determination about the aspect of output of the prediction error ranges of the first route and the second route based on whether or not the prediction error range changes.

  • Patent number: 9573522
    Abstract: Arrangements related to the operation of an autonomous vehicle are described. The autonomous vehicle includes a vehicle seat. It can be determined whether a future planned driving maneuver of the autonomous vehicle includes a change in a current motion of the autonomous vehicle. Responsive to determining that the future planned driving maneuver includes a change in the current motion of the autonomous vehicle, the vehicle seat can be caused to provide a haptic indication of the future planned driving maneuver prior to implementing the future planned driving maneuver. In this way, a vehicle seat occupant can be alerted to the future planned driving maneuver. The haptic indication can include a movement of the vehicle seat. In one or more arrangements, the movement of the vehicle seat can correspond to a sensation that a vehicle seat occupant will experience during at least a portion of the future planned driving maneuver.

  • Patent number: 9573600
    Abstract: A driver-specific vehicle control method is provided that can adjust one or more vehicle control systems in response to a difference in current driver driving characteristics with respect to safe driver driving characteristics on the same roadway type and vehicle operating conditions. The method maintains a driver score for each driver of a vehicle, in the form of a set of the driver's driving characteristics scores for each different roadway type. The method, via a control apparatus, determines a current position of the vehicle on a roadway and the roadway features to select the appropriate driver score for comparison. When the driver's score exceeds a threshold difference from a safe driver score on the same roadway type, the method can adjust a control system parameter.
