Abstract: An electronic control unit (ECU) and a position detection unit are disposed in separate chambers formed in a case. Two switch portions are separately disposed on opposite sides of a movable member of the position detection unit, thus reducing the size of the unit. The signal-related circuit that needs to be connected to the ECU for signal transmission and the drive circuit, for starting the starter motor and turning on the reverse lamps, that does not need the connection to the ECU for signal transmission, are separately disposed on the opposite sides of the movable member, that is, on the case side and a first cover side. The drive circuit is completely separated from the signal-related circuit and the ECU, thus preventing the drive circuit from electrically interfering with the signal-related circuit or the ECU.

Abstract: A slotted rotor is fixed to a manual shaft operatable by using a shift lever. The slotted rotor is turnable in a restricted angle about the manual shaft. The rotor has a slot in arc segment a, slots in arc segment b, slots in arc segment c, slots in arc segment d, and slots in arc segment e that are arranged concentrically about the manual shaft, in that order starting from the manual shaft. As the rotor turns, the slots in arc segments d, e cause incremental pulses to be generated. Based on the number of pulses, a control unit detects deviation from the planned neutral position and establishes a correct neutral position. The position detecting apparatus and method make it easy for a worker to perform the neutral position alignment of a neutral start switch and to maintain the alignment after the switch has been mounted.

Abstract: A continuously variable transmission system includes a belt type continuously variable transmission unit which, in turn, is composed of a primary pulley and a secondary pulley wherein the torque transmitting direction is switched by torque circulation in changeover between forward and reverse travel. When a low mode is selected in a D range, a somewhat higher hydraulic pressure from a regulator valve is supplied, through a manual valve, to a secondary hydraulic servo, which moves one sheave of the secondary pulley, and a somewhat lower hydraulic pressure from a ratio control valve is supplied to a primary hydraulic servo which moves one sheave of the primary pulley. When the D range is switched to R range by the manual valve, the supplies of the above hydraulic pressures are reversed. With this arrangement, the relative axial forces on the pulleys are changed in switching between forward and reverse travel.

Abstract: A continuously variable transmission system includes a belt type continuously variable transmission unit (CVT) wherein the direction of torque transmission is switched by torque circulation between a low mode and a high mode accompanied by a change in the axial forces on the pulleys of the CVT. In the Low mode of the D range, a comparatively high hydraulic pressure from a regulator valve is supplied to a Low clutch hydraulic servo via a low-high shifting valve and to a secondary hydraulic servo. In addition, a comparatively low hydraulic pressure from a ratio control valve is supplied to a primary hydraulic servo. These oil pressure feeds are reversed by the switching of the low-high shifting valve.

When an axial force difference is produced between the primary pulley and the secondary pulley, the belt type continuously variable transmission changes its speed corresponding to a torque transmission direction and normal and reverse rotation directions.
