  • Patent number: 8579745
    Abstract: A control device for a belt type continuously variable transmission of a vehicle such as a motorcycle includes a first storage section for storing in advance reference correlation between a position of a movable flange and a detection value of a flange position detection sensor. A first processing section moves the movable flange to a position where its movement is restricted by a restriction section. A detection value of the flange position detection sensor is stored in a second storage section. A second processing section derives correlation between the position of the movable flange and the detection value of the flange position detection sensor based on the detection value of the flange position detection sensor stored in the second storage section and the reference correlation between the position of the movable flange and the detection value of the flange position detection sensor stored in the first storage section. A detection value of the flange position detection sensor is thereby calibrated.

  • Patent number: 8357063
    Abstract: A belt type continuously variable transmission for a vehicle such as a motorcycle includes a primary sheave and a secondary sheave each having a pair of flanges axially movable relative to each other. A belt is wound around the sheaves. An actuator controlled by a control device moves the flanges. The control device includes a determination section for determining whether the actual gear ratio of the belt type continuously variable transmission has become a predetermined gear ratio for TOP or LOW, and a first correction section for correcting an operation amount of the actuator based on the determination made by the determination section. Control accuracy in a region where the gear ratio is TOP or LOW is thereby improved.

  • Patent number: 8321103
    Abstract: In a transmission control system for a vehicle, in a torque return period at the time of up-shifting of a transmission, an engine torque and a clutch torque are increased in parallel. A target engine torque value and a target clutch torque value are set such that the clutch torque changes at a value higher than the engine torque. The target clutch torque value is set such that a difference between an amount of energy generated in a clutch and an amount of energy generated in an engine substantially coincides with an amount of energy required to reduce the rotation speed of the engine to a target rotation speed.

  • Patent number: 6708068
    Abstract: A machine, functioning as a unit, is composed of a main module and at least one replacable module having an ID. The main module includes (i) an ID recognition unit programmed to receive ID information from each replacable module, and (ii) an action decision unit including a decision algorithm programmed to select an action based on preselected signals. The decision algorithm is adjusted based on the ID information. The at least one replacable module includes (iii) an ID information unit storing ID information identifying the at least one replaceable module, and (iv) an action actuation unit including an action algorithm programmed to actuate the at least one replaceable module based on signals from the action decision unit; wherein the main module and the at least one replaceable module are communicated via an interface. The decision algorithm provided in the main module is adjusted based on the ID information, so that proper control can always be accomplished adaptively to the used replacable module.
