Abstract: A starting-clutch control apparatus is configured to control connection between a driving side and a driven side of a vehicle using a starting clutch disposed therebetween. A driving-shaft rotation speed detector is configured to detect a rotation speed of a driving shaft of the starting clutch. A driven-shaft rotation speed detector is configured to detect a rotation speed of a driven shaft of the starting clutch. A cumulative work amount calculator is configured to calculate a cumulative work amount of the starting clutch based on pressure applied to the starting clutch, the rotation speed of the driving shaft, and the rotation speed of the driven shaft. A torque output restricting device is configured to restrict an output torque of a driving source of the vehicle when the starting clutch is in a transient engagement state and the cumulative work amount exceeds a first specific value.

Abstract: Line pressure is adjusted by one valve for supplying the pressure to control the engagement of a clutch in normal and abnormal operating conditions. In the normal operating condition, the valve control pressure which is controlled by a starting clutch control valve 41 is used for the control of a clutch pressure control valve 42, so the line pressure from a line 61b is adjusted to control the engagement of the starting clutch 5. If there is a breakdown, two electrically controlled valves 41 and 45 are turned off, and the line pressure is applied through another line 64. As a result, the spool of a shift restriction valve 43 is shifted to the left, so the hydraulic oil is supplied to a pitot flange 51. In this condition, the pressure (correspondent pressure) which corresponds to the rotational speed of the engine is supplied as a signal pressure from a pitot pipe 53 through lines 66 and 67 to the shift restriction valve 43. This hydraulic controller adjusts the line pressure in the line 61b by using this correspondent pressure for controlling the engagement of the starting clutch 5.

Abstract: In a control apparatus for an automotive continuously variable transmission having a forward-reverse selector mechanism in which a gear ratio for reverse is set closer to a speed reducing side than a gear ratio for forward and a belt type continuously variable transmission mechanism, a PH pressure that is outputted from a first regulator valve and a PL pressure that is outputted from a second regulator valve are changeably supplied to one and the other of a hydraulic cylinder of a drive pulley and a hydraulic cylinder of a driven pulley via a shift control valve. A hydraulic pressure supplied to a reversing hydraulic pressure connecting element from a reversing manual valve is inputted into an oil chamber of a first regulator valve so that the PH pressure is increased with the hydraulic pressure so inputted.
