  • Patent number: 10427667
    Abstract: The invention concerns a method for automatically controlling a motor vehicle (10) for switching from a “normal” mode to a “freewheel” mode, the vehicle (10) comprising an engine (12) capable of providing engine torque to drive wheels (14) via an automatically controlled clutch device (18) that comprises a drive shaft (15) and a driven shaft (16). A transition step (E1) is interposed chronologically between the “normal” mode and the “freewheel mode” during which the engine (12) is automatically controlled in such a way that the driven shaft (16) and the drive shaft (15) turn at the same speed without transmitting torque to the drive wheels (14).

  • Patent number: 10415656
    Abstract: Provided is a work-machine erroneous forward/backward travelling operation notifying device capable of improving safety by notifying, when a travel direction inputted to an operation input unit does not conform to the condition of a transmission clutch, an operator of the non-conformance. Whether the conditions of clutches 121 to 124 conform to a travel direction inputted to a selection lever 141 is determined on the basis of a pressure Pf sensed by a first pressure sensor 133a or a pressure Pr sensed by a second pressure sensor 134a and the travelling direction inputted to the selection lever 141. When it is determined that the conditions of the clutches 121 to 124 do not conform to the travel direction inputted to the selection lever 141, a vehicle 10 is notified that an erroneous operation will occur.

  • Patent number: 10408343
    Abstract: A continuously variable transmission pump limited stop controls system includes a continuously variable transmission (CVT) including primary and secondary variator pulleys. The primary and the secondary variator pulley each have a mating half with a conical face, defining a variable-width gap between each pulley and its mating half. A flexible member is positioned within the gap and is movable on the conical faces defining a CVT ratio. A secondary pulley valve controls flow of a fluid to the secondary variator pulley. A secondary pulley pressure boost system identifies if a rapid stop event is occurring and issues a command to fully open the secondary pulley valve during the rapid stop event. As the CVT ratio reaches a predetermined threshold of a desired relaunch ratio during the rapid stop event, an engine speed request is issued to an engine connected to the CVT to increase engine speed.

  • Patent number: 10371256
    Abstract: In a vehicle on which a torque converter having a lock-up clutch is mounted between an engine and a transmission, a meet point learning controller is provided to perform learning control for obtaining a learning value based on information on a meet point at which the lock-up clutch starts torque transmission. The meet point learning controller estimates a LU transmission torque based on a difference between an engine torque signal value and a torque converter transmission torque when the lock-up clutch moves from a non-engaged state to an engaged state during traveling of the vehicle, and uses, as the meet point information, a meet point detection pressure at a time when the LU transmission torque estimated value is determined to have entered an upward trend.
